How the gas water heater works

gas water heater

Will gas water heater work without electricity? 

When you turn on the hot water faucet, you expect hot water to come out within a few seconds, maybe a minute later. Then one time you turn on the hot water faucet and there is no hot water, no matter how long you wait. So, you go check your gas water heater and notice the tank isn’t warm to the touch. What does this mean?

First, if you don’t know, see if your gas water heater has a power cord and if it does, is it plugged in?  If it is unplugged, plug it in. If it is plugged in, check the breaker box and if the circuit to the water heater is off, flip it back on. Wait a few minutes and see if the water gets hot. 

Maybe, it depends on the type of pilot light.  A gas water heater definitely does not need electricity to heat the water, but if there is a power cord from the gas water heater to a wall outlet, then your gas water heater depends on electric power to ignite the pilot light. 

A gas water heater that is designed with a continuous gas pilot light should keep functioning even with an electrical power outage. With that a continuous gas pilot light, a gas water heater and power outage is the better combination. Many homeowners prefer a home with both electricity and gas appliances just reasons like power outages. When the electricity is off, then you still have gas to cook with, heat your home, and with the continuous gas pilot light, you’ll still have hot water.

 A gas water heater with an electric pilot light will even keep working if it doesn’t rely on electricity. However, if your gas water heater does rely on the electricity, it will usually keep hot water in the tank for a few days during a power outage. 

What causes a water heater to not stay lit?

The most common issue for gas water heaters that won’t stay lit is the thermocouple. The thermocouple is a device that measures the temperature of the water and regulates the gas flow inside the gas water heater. A gas furnace has a thermocouple too. 

There are 2 wires coming from a thermocouple on your gas water heater, one to the thermostat and one to the pilot light. When the wire to the pilot light gets bend, damaged, or dirty, it can’t send the electric signal to open the gas valve so that the needed combustion can take place. 

Can a gas water heater leak?

Yes, a gas water heater can leak either gas or water. If it is a gas leak, turn the gas supply off immediately. Every gas water heater is installed with a dedicated gas valve at the gas line. Turn this to the off position and call a plumber immediately. 

If it is the water leaking from your gas water heater, turn the water off to the water heater tank using the dedicated shutoff water valve at the cold water inlet pipe. There are two options your gas water heater may have: 

  • Gate-style valve: This type of water valve is a wheel. You need to turn the valve clockwise as far as it will turn. 
  • If the shut-off water valve is a ball-style, turn the handle 180 degrees.
  • If either water valve is broken, turn the water off at the main water shut off valve. This will shut the water off to your entire house. 

Why is gas water heater leaking?

There can be a variety of reasons a gas water heater begins leaking water.  You can inspect the following to determine the leak yourself or call a plumber for service.  

  • The inlet and outlet: This is where the water pipes connect to the gas water heater. Make sure the cold water intake and the hot water output connections are tight and not leaking. You can tighten them using a pipe wrench.
  • The T&P valve: This is the pressure relief valve, and it is designed to release water in case of a pressure build up, it is a safety feature to keep your gas water heater from blowing water out from other areas of the water heater. 
  • The thermostat settings:  Make sure the thermostat settings aren’t turned up too high. This can cause the pressure at the hose bib and cause your gas water heater to leak water. Most gas water heaters are set at 140 degrees by the manufacturer. 
  • The water pressure: Check the water pressure at the hose bib. An inbound water pressure that is more than 80 PSI, you need to have a PRV (pressure reducing valve) installed.  
  • The drain valve: The drain valve is at the bottom of the water tank and should be closed at all times. Depending on where your gas water is located, it could accidently be opened and start leaking. 
  • The water heater bottom: If there is water leaking from the valve, it will run down the tank sides, making it seem the tank is leaking. If you have determined that is not where the leak is coming from using the steps above, then check the tank itself along the seams and at the bottom. If you gas water heater is leaking at any of those areas, your water neater needs to be replaced.

If you aren’t able to determine where the water leak is coming from, call a plumber for assistance. 

If I need to replace my gas water heater, which gas fired water heater should I get? 

Buying a new gas water heater is an investment in your home, and while they aren’t super expensive, you don’t want to have to replace it again too soon either. So, choosing one that will give you a few years is important. The following are three of the top recommendations by many experts:

  • BEST OVERALL GAS WATER HEATER: Rinnai High Efficiency 6.5-GPM Tankless Water Heater
  • RUNNER-UP GAS WATER HEATER: A.O. Smith Signature 40-Gallon Water Heater
  • BEST FOR THE MONEY GAS WATER HEATER: Sure Comfort 40-Gallon Natural Gas Tank Water Heater

What size gas water heater do i need?

The best way and most recommended way to determine what size of gas water heater you need is by how many people live in your home. A 40-gallon gas water heater is typically plenty for a household of 4 people. The following is the basic recommendations: 

  • One to two people—23 gallons to 36 gallons capacity
  • Two to four people—36 gallons to 46 gallons capacity
  • Three to five people—46 gallons to 56 gallons capacity
  • Five or more people—no smaller than 56 gallons capacity adding 10 gallons for a 6th and 10 gallons for every additional person

With the purchase of a gas water heater, where is the best place to install it?

When installing a new gas water heater, you’ll need to check with the local governing offices if there are building codes and regulations in regard to where a gas water heater should be installed. Every city, every county is different in every state. By having your gas water heater installed by a professional plumbing contractor, they know these codes and regulations or who to call to get the information. 

Why should you choose to go with a gas water heater? What are the advantages between a gas water heater vs electric? The price points are different when it comes to the different water heater types, which is usually the deciding factor for most homeowners.

With a gas water heater, it will use natural gas instead of electricity. When there is a power outage, as we discussed earlier, you could still have hot water. 

While gas is a dangerous power source, known for explosions and fires, gas water heaters today have ingenious mechanisms that make it highly unlikely to happen.

For the power, gas is cheaper than electricity. However the purchase point of the gas water heater is more than an electric. You do get your money back fairly quick though with the gas water heater. Need gas water heater installation in Chattanooga, TN? Call 423-718-7342 today!

What is the most common problem with water heaters?

If you’re like most people, when your water heater quits working, you replace it. You don’t think about water heater repair being a possibility, probably because they are a mystery.  We aren’t sure what’s going on inside that tank that produces the hot water for our morning shower, but we do know without it, that shower is cold! 

Today, we’re going to answer some common hot water heater repair questions, or should it be replaced, and hopefully give you a little more knowledge about this big tank. 

The water heater in your home is working hard to provide your family hot water when you need and want it. Just like you, the water heater gets tired and because it doesn’t get any paid time off, it will begin to weaken and start having problems. For of the most common problems for water heater are as follows, along with tips on doing your own water heater repair. Before you start any troubleshooting and repairs, turn the circuit breaker off first: 

  1. Water temperature – The water temperature is a common issue households have with their water heater. There are three things that can be the problem: 
    • Cold Water – Check the circuit breaker and make sure it is in the on position or replace any fuses. Make sure the water heater power switch is in the on position. Then as a last resort, make there the water heater is getting power. 
    • Insufficient Warm Water – If the water is only getting warm, the water heater you have may not be large enough for your household. First check the cold and hot water connections to make sure they are turned on and not switched by turning the water supply off. Then turn the hot water faucet on, and if water is flowing out but cold or warm, then your connections are reversed. If that isn’t proving to be the problem, then call your plumber for water heater repair service. 
    • Too Hot Water – If the water is getting too hot, you can lower the thermostat a few degrees. The recommend temperature is 120° F for a balanced and efficient heat level. 
  2. Leaks – Try to do your own water heater repair by checking for loose connections and tighten them. Check the heating element bolts and tighten if loose. If the leak appears to be coming from the heating element, you’ll need a professional plumber water heater repair service. If the tank is leaking, it is time to replace your water heater.  A water heater leaking can be caused by a few different issues like these:  
    • a faulty T&P valve (temperature and pressure valve)
    • inappropriate water pressure
    • water heater overheating
    • valve stuck
    • a plumbing connection leaking
    • bolts loose to heating element 
    • gasket gone bad 
    • the tank is leaking
  1. Water is Discolored – Dirty, rusty looking water coming from your water heater usually indicates either the anode rod needs replacing, or the lining has rusted. If a water heater repair of replacing the anode rod doesn’t stop the dirty, rusty water, then it is time to replace the water heater. 
  2. Noises and Sounds – A water heater should be fairly quiet, but when sediment has built-up in the tank, it will cause odd noises and sounds. A fairly easy water heater repair that may fix this is to flush the tank. The owner’s manual will provide instructions on how to do this. If you don’t have the manual, you can find instructions online. If the odd noises and sounds continue after flushing the water heater, you’ll need replace the water heater. 

What would cause a hot water heater to stop working?

Hot water is a luxury that we assume will always be there when we need it, but one day, there is no hot water for your morning shower. It was working fine last night, what could have happened overnight?

  • No Power: Whether you have an electric or gas water heater, if the power source is connected or working, you’re not going to have hot water. If all the other electric or gas appliance and features of your home are working, then you need to check the circuit breaker or the gas connection to the water heater. If these check out okay, you need to schedule a water heater repair service call. 
  • Cold Water: If all you’re getting is cold water, it could be the built-in thermostat, your water heater may have two thermostats. Did you know that a thermostat can fail though, and when it does, all you’ll get is cold water. A professional plumber can complete a water heater repair for this type of issue quickly and save you from buying another unit. 
  • Sludge Clog: If you’ve never drained and flushed your water heater, it probably has built up sediment and sludge in the tank. This can keep a water heater from heating the water, or worse, cause the tank to leak and flood your home. Call a professional plumber for water heater repair to drain and flush your water heater, or you can do this yourself following the instructions in the owner’s manual. 
  • Water Heater Age: Water heaters last on average, a maximum of 12 years and by the time they are 10 years old, they start performing poorly. If you have had several water heater repair calls in the past year and the unit is 8 to 10 years old, it is time to buy a new water heater.

What are the signs your hot water heater is going out?

Here are some key indicators that a water heater repair isn’t going to keep you hot water any more and it is time to buy a new one: 

  • The Age: Unfortunately, your water heater, like all the other household appliances, won’t last forever. You can usually get 10 years from a good quality unit that you’ve taken the maintenance steps like draining and flushing duties. Having a water softener installed will give your water heater a longer life too and require less water heater repairs. The first 2 numbers in the serial number will tell you the year your water heater was manufactured. 
  • Leaks:  A leaking water heater is never a good thing, and it isn’t always visible. Often, a water heater has a small leak behind it dripping into the drip pan. Check your water heater connections all around it and on top, if you see any leaks, all a professional plumber for water heater repair, or you may need to replace it, the plumber can give you the best advice. 
  • Cloudy or Rusty Water: When the water is coming out of the faucets is cloudy or rusty, or has a metallic smell, it could be the pipes between the water heater and faucets, or it could be inside the water heater tank. A possible water heater repair would be replacing the anode rod but depending on the quality of the water and the age of the water heater, then you need to get a new water heater. 
  • Short on Hot Water: If you run out of hot water fast or it takes forever to get hot, your water heater is about to quit. If you have taken the recommended maintenance steps of draining and flushing your water heater and you’re still having these issues, you definitely need a new water heater. 
  • Water Temperature Varies: Three things can get your morning off to a bad start. One is no coffee, two is no water heater, and the third is the hot water gets cold, then hot, then cold again. When a water heater isn’t keeping hot water flowing steadily in your morning shower, it is time purchase a new water heater. 
  • Strange Sounds: If your water heater has popping and rumbling sounds coming out of it, that is a sound of needing a new water heater. This sound is emitting because there mineral and sediment buildup formations inside the tank hardening. With that extra thickness inside the tank, the water heater is not heating water efficiently and it is highly likely the tank could crack any time now and flood your house. 
  • Expensive or Multiple Repairs: A regular tune-up for your water heater shouldn’t be costly. As it gets older and parts begin to wear out, however, maintenance work will likely get more expensive. Smart homeowners know to compare the rising cost of fixing the unit with a replacement. When repairs become too expensive, replacing the water heater will be the clear solution.

How many years does a water heater last?

A good quality water heater with recommended maintenance by the homeowner, i.e. annual draining, and flushing, keeping connections tight, will give you a lifespan of 10 years or more, some have even lasted 20 years. Without the recommended maintenance, you can expect a lifespan of 8 years or less. Call 423-718-7342 today for your water heater repair needs in Chattanooga, TN.

What is high recovery water heater?

high recovery water heater system

How is water heater recovery rate calculated?

When you use up all the hot water, your water heater has a recovery period before it will have hot water again. Every brand and model has a different recovery period, of course the better the brand and model, the faster the recovery. However, each brand has its own model of high recovery water heater, with the average around 55 gallons within an hour. 

What that means to you  is that with a high recovery water heater, your 50 gallon capacity water heater will be able to furnish you hot water in an hour.  What is the difference between a high recovery water heater vs regular water heater? The water heaters with less recovery will have up to 40 gallons of water heated within that same hour. 

The recovery rate is the volume of hot water a water heater can produce during a specific time frame. There are several factors that can affect that volume of hot water be produced: 

  • Heating element wattage
  • Size of burner
  • Temperature setting
  • Time frame allowed

The Recovery Rate is commonly specified out by the number of  gallons that are produced based on a 100º ascent in temperature within an hour. Today, 90 degrees is used for the baseline in most places versus the 140 degrees in the past. 

To determine how long it will take a water to recover the amount of water drained to get at the same temperature, this generic number is an example of how to calculate that information: BTU times recovery efficiency = pounds of water heated one degree. Take that number and divide it by 8.33 then divide that by the required temperature increase desired. 

How long does it take for a water heater to fully recover?

Water heaters may be the hardest working appliance in every home. It is faithful in creating hot water for every bath, load of dishes or laundry, and cooking. The average home with 1.5 bathrooms have a forty-gallon water heater. 

The hot water recovery time varies between electric water heaters and gas water heaters. An electric forty-gallon water heater will recover the spent hot water in two hours on the average.  A forty-gallon gas water heater recovers its spent hot water within one hour. 

What is recovery efficiency in a water heater?

For example, a gas water heater is said to have a recover rate of 75%, meaning that 75% of the gas burner heat is actually used to heat the water and 25% of the heat is wasted up the vent.  An electric water heater however, with a heating element that is immersed has 99% recovery rate, meaning only one percent of the energy is wasted. 

It is important to note that while an electric water heater uses less energy to heat the water than a gas water heater, however, because the gas unit takes less recovery time, less gas is used compared to the amount of electricity used. A 50 gallon high recovery water heater offers hot water fifty percent faster than a standard 50 gallon water heater. This attracts the attention of homeowners a jacuzzi or teenagers. 

How do I know if my water heater is working?

The following are indications that your  water heater is not working: 

  1. You run out hot water: If all you’re able to get from your water heater is one shower or one load in the dishwasher, then you need to replace your water heater. If you have a busy household, aka, kids, then consider upgrading to a high recovery water heater. 
  2. Water temperature varies: If you have really hot water one time and the next time you have to wait for it to get lukewarm, it is time to replace that unit with a new water heater. 
  3. Leaking water heater: when you hear water dripping in the drip pan or you find water in the floor around the water heater, it is past time to replace the unit. 
  4. 4. Water flow reduced: If you have  sudden drop in water flow or water pressure, it could be your water heater needs to be flushed to remove any buildup of sediment. However, if your water heater is close to 10 years old or older, replace it now!  
  5. Noises and sounds: A water heater should not be noisy to the point you hear it above everything else in your house. Any banging, boiling, cracking, or gurgling sounds indicates your water heater is full of sediment and sludge. Flushing it out may help, but chances, it simply needs to be replaced. 
  6. Discolored and smelly water: When you notice a strange odor like rotten eggs coming from your water faucets, or the water heater smells like burning, or the water is discolored in a muddy or rusty color, that water heater is done. That is what you’re bathing in and cooking with and it is full of bacteria you don’t want to ingest.
  7. The age of your water heater: The average water heater will give you up to 10 to 12 years of use, after that 10th year, start shopping for a new water heater.

Which type of water heater typically has the highest recovery rate?

The best high recovery water heater is an electric unit. Electric water heaters for residential use typically have a one-hundred percent recovery efficiency because of the immersion-style elements.

Keeping your water hot

How often do you practice water heater maintenance? If you’re like most homeowners, probably never. We have a new water heater installed and life goes on every day with bathing, cleaning, and cooking.  Until the water starts giving us problems again, maybe 10 years later. In our piece today, we’re going to answer some basic questions about How to maintain a water heater and help you get more than 10 years from your water heater. 

To get a longer lifespan from your water heater, you should have a Water heater maintenance checklist and follow it just as you do for changing the HVAC air filter and other household duties. How do you maintain a water heater? Here are six easy and inexpensive things water heater maintenance steps that will extend the lifespan of the water heater and increase its operating efficiency. Following these steps, you can avoid expensive Water heater maintenance and repairs. 

1. The TPR Valve

  • Turn off the power and the cold-water supply.
  • With a bucket placed under the pipe connection to the TPR (temperature-pressure-release) valve, usually located on the top or side of the water tank. 
  • Lift the tab to release some water from the tank then let go. If water doesn’t stop flowing, partially drain the tank and with pipe wrench, unscrew the old valve and install a new TPR valve.

2. The Anode Rod

  • Attach a hose to the drain cock on the tank to release some water.
  • Using a 1 and 1/16-inch socket with hex head, unscrew the rod and if there is half inch thick calcium build-up, replace it with a new one, wrapping the threads with plumber tape and return to tank, securely tightening it. 

3. Drain Tank, Rinse Out Sediment

  • Drain any remaining water into the bucket and open the cold-water valve to stir up the sediment in the tank’s bottom. Drain and repeat the process until clean water is coming from the hose
  • Shut the drain cock and refill the tank, the turn the power on.

4. Tweak the Temperature

  • Unscrew the cover on the temperature dial and with a flathead screwdriver, remove the cover and adjust the temperature dial to 120 degrees. For every ten degrees you lower the temperature, you’ll save as much as five percent in energy costs.
  • If you’re not home for 3 or more days, you can turn the water heater off or turn the thermostat down to the lowest setting.

5. Pipe Insulation

  • Slide 3/8-inch-thick foam insulation that will matches the pipe diameter over both the cold and hot water pipes.

6. Heater Insulation

  • Cut an insulating blanket so that it fits around pipes, temperature control, and TPR valve that are outside the tank.
  • Wrap the tank and then use foil tape to seal the cuts. Do not cover the top!  

Do water heaters need maintenance?

A water heater is like any other basic household appliance – it needs to be maintained and kept up to get a longer lifespan.  When a water heater maintenance is properly cared for, you can get up to 12 to 15 years lifespan. Recognizing the following signs and addressing them as soon as possible, you could extend its lifespan, or have is professionally repaired or replaced before it leaves you without hot water. 

Inconsistent or no heat

Obviously, if there is not any hot water at all, there is a problem with the water heater. If the heat is fluctuating, that is an indication the heating element is covered in mineral deposits, blocking, and interfering the heating process.

Low pressure 

Mineral build-ups can block the water pipes that are connected to the water heater.

Strange sounds

A water heater should naturally make some sounds, but when those sounds get so loud they are disturbing the household, it may be time to replace the unit. Loud banging, cracking, or popping sounds need to be addressed.

Water pooling at base

If the water heater has water puddled around the base or is leaking, it could be under high pressure that needs to be released or it could be cracked and needs to be replaced. 

What is the lifespan of a water heater?

Water heaters did good to last ten years not that long ago, but today, water heaters are designed better and last longer than those older models. With water heater maintenance routine, a water heater can last as long twelve, even fifteen years.  The condition of the water running through the water heater can affect the lifespan as well.  This is why water heater maintenance is so important to stay on top of with a regular routine.

Electrical water heater system

How do you know your water heater is going?

Here are four signs you have a bad water heater and should schedule your plumber soon to replace the unit: 

  • Water heater age: Knowing how old your water heater is will tell you that is nearing the end of life. The serial number on the tank will usually provide that information.
  • Rusty water: When rusty water is coming out of the hot water faucet, this indicates the tank has rusted inside and will only be a short time before it busts through and starts leaking. 
  • Noises and rumbling: The older a water heater gets, the more sediment build ups inside and on the bottom. That sediment hardens and the water isn’t able to flow through and heat as efficient as it should.
  • Water on floor: If you notice water around the base and on the floor, the tank may have a crack and is leaking on the floor as it contracts and expands.

We recommend a routine of regular water heater maintenance, but how often should a water heater be serviced? For most homeowners, it is recommended a water should be flushed every six months. If you live in an area with hard water, you may consider installing a water softener and flushing your water heater every three months. Need water heater maintenance in Chattanooga, TN?

Can Tankless Water Heater Heat Whole House?

A Tankless Water Heater in a Shower.

Can tankless water heater heat whole house?

If you are thinking about installing a tankless water heater, you are probably wondering if it will be sufficient to heat all the hot water in your home. Largely, this will depend on the size of your home and the size of the system you choose. You will need a larger tankless unit to heat the whole home than you would to heat a particular appliance or section of your home. Several manufacturers produce such units. When you are looking for professional tankless water heater installation in Chattanooga, TN, search no further than Chattanooga Water Heater Co.. We offer a full range of water heater services. Learn more by calling 423-718-7342.

Which is better tank or tankless water heater?

If you’re planning to replace your water heater, you might want to consider a tankless system over a standard tank water heater. People choose tankless systems because of the appeal of getting hot water on demand. Because you draw hot water as needed, instead of heating water in a storage tank, you’re also saving energy, so tankless systems are generally more energy-efficient than tank systems. One drawback tankless systems have is the ability to heat a whole household using one system.

Tankless systems are also valued because they are so much smaller than a tank system. But this small size means you often have to install more than one system to meet a large household’s hot water demand. A smaller tankless unit can get overwhelmed when demand is high and it can take it longer to heat water. Some manufacturers, however, produce large units that will meet the demand of a larger household. Another disadvantage of tankless systems is the higher cost of installation, although this cost is often offset by long-term energy savings. Tax rebates are also sometimes available.

Is a tankless water heater worth it?

Energy savings and endless hot water draw people to tankless water heaters. But are these the only reasons you’d want to have one installed in your home? What is the downside of a tankless water heater?


  • Delivers on the promise of hot water on demand.
  • Lasts almost 20 years, or about twice as long as a tank water heater.
  • As much as 22% more efficient than tank systems and reduces the cost of “standby loss” because it only runs when needed.
  • Even the largest units take up much less space than a tank system.
  • Tax credits available in most cases.
  • Longer warranties are usually offered.


  • Hot water temperatures can be inconsistent.
  • Initial installation costs are high.
  • Can get overwhelmed by demand trying to supply several outlets at once.
  • Additional equipment like water softeners often needed.
  • Gas lines sometimes have to be rerouted.
  • Annual maintenance required so warranties remain valid.

Can you run out of hot water with a tankless water heater?

Technically, a tankless water heater can never run out of hot water. Hot water that can be depleted isn’t being stored in a tank. Instead, water is heated as it’s needed. Why does my tankless water heater go cold? While your tankless system can’t technically run out of hot water, you might occasionally find yourself initially taking a cold shower.

When demand is high the system can get overwhelmed. This can happen if two or more outlets are being used at the same time and the system is too small to handle it. It’s also possible cold water could be lingering in the pipes and you might get an unexpected chill before the hot water comes out.

Can tankless water heater be installed in attic?

For the most part, you can install a tankless water heater anywhere there is room in your home, including in the attic. If your tankless system is gas, you will also need to make sure there is proper ventilation to release toxic gases like carbon monoxide. Moreover, with gas appliances of any kind, you have to have enough combustion air available for the appliance to work. This means there must be enough air around for combustion to occur consistently.

Can tankless water heater be installed outside?

Both gas and electric tankless water heaters can be installed outside. In fact, some gas tankless systems are made specifically for outdoor installation and you will have to choose between interior and exterior models when putting a new tankless system in. Electric tankless systems will need to have some kind of shelter installed over them to protect them from the elements.

What are the signs of a failing water heater?

Lack of hot water is usually the most common sign your water heater is on the brink of failure, but you’ll want to stay alert to these other problems:

  • Popping or rumbling noises usually indicate mineral and sediment build-up are affecting the system. If the sediment is flushed and the noises persist, there could be a crack or leak.
  • Cloudy water means you have heavy sediment buildup, while rusty water means either your water heater or plumbing pipes are rusted and need to be replaced.
  • A faulty pressure relief valve will either be leaking or restrict hot water flow when it’s tested. It will need to be replaced. Leaving it unchecked could lead to dangerously high pressure building up and possible bursting or even explosion.
  • A leaking tank will require you to replace your water heater.

By having a regular water heater inspection, you can often safeguard your water heater, yourself, and your property from serious and expensive problems.

What happens if you don’t flush your water heater?

When you don’t have your water heater flushed—a task often performed with a water heater inspection—sediment will build up in the tank, which can cause a variety of problems. Sediment build-up can cause the tank to corrode, which eventually leads it to crack and leak. This build-up can also cause your pressure relief valve to clog, and that can lead to your water heater bursting or exploding. 

Do home inspectors check water heaters?

A good home inspector will inspect water heaters very thoroughly, looking for leaks or other signs of corrosion or sediment buildup that could lead to serious damage and expenses. If your water heater failed inspection you’ll want to make sure it’s repaired before you sell your home. If you don’t repair it, you might have to renegotiate the price on your home so the buyers can make necessary repairs.

Water heater inspection after installation

When you have a new water heater installed in your home, it will have to be inspected immediately afterward. The inspection will ensure that the water heater was installed properly. It may also detect minor issues with the new unit that can be corrected. You want to make sure the unit was installed correctly as incorrect installation can lead to dangerous situations that can harm you and your property. If you are installing the water heater yourself, you should check your city permits office for any required permits.

Reliable Water Heating Units

Natural gas is one of the cleanest forms of energy we have today. It is popular, and preferred, by restaurants for cooking and when it comes to hot water, a gas water heater heats the water up faster than an electric unit.

To learn more about a gas water heater for your Chattanooga, TN, dial 423-718-7342 to connect with the experts at Chattanooga Water Heater Co..

Can water heaters last 20 years?

The typical warranty for a gas powered hot water heater is usually five or six years. A higher quality, more expensive brand will have a ten-year warranty. Gas water heater made of fiberglass will typically come with a lifetime warranty and a stainless steel gas water heater will last even longer than a conventional unit.

gas water heater

How long should a gas water heater last?

A manufacturer’s basic warranty for service life of a gas water heater is eight to twelve years. Where the water heater is used can affect the lifespan based on the water quality. Professional installation can affect the lifespan, and the homeowner’s diligence of maintenance can all affect the life span. With all things in an ideal situation, you could get up to thirteen years or longer.

How do you know when your water heater needs replacing?

Here in Chattanooga, Tennessee, like anywhere else, the water heater is an essential appliance for the household. We’re taking bathes or showers, we’re washing dishes or cooking, or we’re doing laundry. Not a day goes by that you won’t use you gas water heater. If you aren’t sure how old your gas water heater is, or you do know and wonder if it is time to replace it, here are some signs that will tell you it is time to get a new water heater:

The Age

If you aren’t sure how your gas water heater is, look for the manufacturer’s serial number tag. The first two numbers of the serial number are the year they manufactured your gas water heater. If you can’t find that tag, use the manufacturer’s website and they may have a source to determine the age.  A gas water heater that is ten years old needs to be replaced unless you have a history of the unit. 

Water is Rusty

If the hot water coming out of your faucets is rusty, your gas water heater is probably rusted inside the tank. Drain your water heater into several five-gallon buckets and if any rust comes out, you need a new gas water heater. Metallic tasting water or muddy looking water is a sign that a new gas water heater is needed.

Insufficient Hot Water Supply

If one load of wash keeps you from getting a hot shower, your gas water heater has probably reached its end of life. Overtime, sediment from the water will build up inside the water heater tanks and eventually, it can’t keep a supply of hot water. This is one reason manufacturers recommend draining your gas water heater ever two to three years to keep that sediment level minimized. 

Clanking and Rumbling

A gas water heater should be relatively quiet, but as they age and that sediment builds up in the tank, it is heated and reheated, eventually hardening. A lot of energy is wasted and you’re not getting full use of your water heater.  When you hear clanking, rumbling, or other noises, you’re probably running out of hot water faster too, it is time to replace the unit with a more energy efficient unit.

Leaking Gas Water Heater       

Metal contracts and expands with cooling and heating. If there is the smallest fracture in the gas water heater tank, you’ll probably notice sooner than later that your gas water heater is leaking. What if you don’t see any fractures or water leaking from the tank, but there is water in the floor around the water heater? Check all the connections and fittings to make sure none of it has come loose. Check the drain pan and if there is water there, your gas water heater is leaking from the bottom. 

How do I know if my gas water heater is bad?

Reviewing the signs of a gas water heater reaching its end of life are the same signs that a water heater is bad. If you’re not getting any hot water from it, it is already beyond those signs, and if you don’t know the exact age and can’t find the serial number tag, it is probably an old model that should have been replaced long ago.

How do you troubleshoot a gas hot water heater?

No hot water? First thing you want to check is the pilot light. Towards the bottom of the tank you’ll find an inspection window. Check there for either a small flame or an LED light, depending on how old your gas water heater is. If no flame or light, then the pilot light has gone out and needs to be relit. Your water heater should have instructions on the side of it how to relight it. 

If the pilot light on the gas water heater will not light, then check the electric spark needed isn’t getting to the pilot. This could be because the gas line has air in itand needs to be purged.  Or the gas supply valve is turned off. It should be in a parallel position with the gas pipe.

Sometimes, the thermocouple could be defective, which is easy to replace yourself if you have any mechanical ability. If not, call a professional plumber to replace it for you. The gas pressure may be too low, which will need to be checked by a professional plumber or your gas company.

What is a High Recovery Water Heater?

A Technician Services a Water Heater.

What is a high recovery water heater?

When choosing a water heater for your home and household, you’ll need to consider several aspects including size and what kind of fuel—usually gas or electric—the water heater will run on. In addition to size and fuel type—natural gas is the most common—you’ll want a unit that is energy efficient and recovers hot water quickly. A high recovery water heater might be an option for you, especially if you have a large family that uses a lot of hot water. These are units, usually larger, with extremely fast recovery times. You can find labels on the unit that show its energy efficiency and recovery time or first-hour rating (FHR)—how quickly it heats water. When selecting your water heater, FHR is a key measure, and you’ll want a unit that can manage your household’s usage. The higher the FHR, the higher the recovery.

While most households with a one-and-a-half bath can operate fairly efficiently with a 40-gallon tank for larger households, a bigger tank—50 gallons or more—is required. These bigger tanks often have higher recovery times. One of the best ways to determine what kind of water heater you might need is to talk with a plumbing professional, especially one that specializes in water heaters like Chattanooga Water Heater Co.. You can also get help with high recovery water heater installation in Chattanooga, TN. Learn more about how we can help by calling 423-718-7342

What is a good recovery rate for a hot water heater?

If your household uses a lot of hot water, a high recovery water heater may be right for you. These units are usually larger—50 gallons or more—but the size of the tank isn’t what matters the most, it’s the recovery rate. This number measures how quickly in an hour it takes your water heater to heat water to 90 ¼ degrees. The number appears as gallons per hour (gph). A normal 50-gallon unit heats water at around 40 gph, and the higher the gph, the faster you’ll get hot water, and the more you’ll be able to use at any one time. Some heavy-duty models get 50-60 gph, and certain brands can produce almost 160 gph. What’s best for your household should be determined by how much hot water you use. You might have a large household that uses very little hot water or a small family with young children that uses a lot of water for baths, laundry and cleaning. The small family, in this case, might need a unit with a high recovery rate. 

High recovery water heater vs regular

When choosing between a high recovery water heater and a regular unit, you’ll weigh the advantages and disadvantages of both.

  • Regular water heaters are less expensive and cheaper and easier to install 
  • Regular water heaters are less efficient than high recovery.
  • For gas heaters, the room where it is installed must be fire-rated and venting must be adequate
  • High recovery water heaters are more efficient and cost less to operate.
  • Hot water is created much more quickly with high recovery.
  • No fire-rated room is required.
  • Installation costs can be higher for high recovery units, depending on venting.

How long does it take for a 50 gallon water heater to run out of hot water?

In general, a standard water heater will deliver about two-thirds of its capacity at a time. If you use about 2 gallons of hot water per shower, a 50-gallon tank will run out of hot water after about 17 minutes. It will take about 20 minutes for the tank to refill and another 20 minutes or so to heat back up.

How long does it take for a 40 gal water heater to recover?

The time for a 40-gallon water heater to recover will depend on whether it is gas or electric. A gas water heater will take about an hour to recover, while an electric water heater will take about two hours. If you have a high recovery water heater, which normally has a larger tank, it will heat the water in much less time, on average about 20 minutes.

Electric water heater with a high recovery rate

Recovery rates for electric water heaters will vary. A key to a high recovery rate for an electric high recovery water heater is the wattage of the unit’s heating element. A small 750 watt heating element will only heat 3.4 gph to 90 degrees, while a 6,000-watt unit can heat water to 90 degrees at 27.3 gph. 

High recovery gas water heater

Typically, if you are getting a high recovery water heater, you’ll be getting a gas water heater. The recovery rate is figured on BTU (British thermal units). A 30,000 BTU unit will raise the water temperature to 90 degrees at 30.3 gph, while a 100,000 BTU unit will raise the temperature to 90 degrees at 101 gph.

A Plumber Connects a High Recovery Water Heater.

How often should a water heater be serviced?

Today, it would be hard to imagine living without a water heater in our lives. We’ve become accustomed to this appliance in our home, our businesses, everywhere. We use hot water for bathing, cleaning, and cooking. There are industries that use hot water to create steam.

It isn’t a law when it comes to the frequency of water heater maintenance how often. Experts recommend it to have a regular water heater maintenance schedule for inspection and service of your water heater. The purpose of this is for you to get the longest lifespan possible.

Every two months, experts recommend checking the plumbing joints for corrosion as a part of your water heater maintenance schedule. If your water heater is gas-powered, make sure there are no flammable products around it.

Experts also recommend draining your water heater every 5 years to remove the sediment that builds up inside water heaters. You should replace the anode rod every 2 to 3 years, and they recommend that you should have this done by a professional as it entails many internal workings.        

How do I shut the water off to my water heater?

Gas and water leaks are two things that scare people about working on a water heater. If you know how to turn off both the gas and the water, it isn’t so scary, so even if you hear an alarm going off from the water heater, don’t panic. Turn off the gas and water, then call the plumber. Now, let’s earn how to turn that gas and water off so you can proceed with your regular water heater maintenance schedule that will keep your new water heater going for a long time. 

  • Disconnect the Water Heater from the Power Source – if it is an electrical heater, turn off the power at the circuit breaker. If you have a gas water heater, turn the thermostat to the lowest point. 
  • Turning the Water Off – Only after you are 100% sure the electricity is off, find the handle on the water heater and if it is a circular handle, turn it to the right. This will open the cold-water flow, turning off the hot water to the kitchen and bathroom. If you aren’t sure where the water turns off at the water heater, turn off the main water supply to your house. 

How do you drain a water heater for maintenance?

Once you have the electricity and water off going to the water heater, the tank is drained through a connection at the bottom of the tank with a water hose. After inserting the hose there and running it outside or into a tub and allow the water and sediment to drain out. This is one of the biggest things you can to with your regular water heater maintenance schedule that will extend the life of your water heater.

Can I flush my own water heater?

Definitely! Making it part of your water heater maintenance schedule, flushing your water heater will help extend its lifetime. The first thing you need to know is where the cold-water spigot is on the water heater tank. Hook up the water hose as described above and turn the cold water on, allowing it to run until the water coming out of the hose is clear.

How do you know when to replace a hot water heater?

Everyone in your household uses the water heater every day. When you consider the number of times, each person uses hot water, you can better understand the demands a water heater has to meet and why eventually, a replacement water heater is needed. It doesn’t have to be a surprise outage though.

A water heater will not last forever, we’ve discussed this. An average lifespan of a water heater is eight to ten years, some have lasted as long as 20 years. If your water heater is close to its 8th anniversary, you should start paying attention to these indications: 

  • Rust on the tank, in the water, or both
  • Rusty inlet/valve
  • Rusty pipes
  • Gurgling and popping noises
  • Leaks around the bottom
  • Won’t heat water

By performing a regular schedule for water heater maintenance, these are the things that you will prevent from happening too soon and keep your water heater around a little longer.

Create a water heater maintenance checklist and follow this with your regular water heater maintenance routine: 

  • The Pressure Relief Valve: the pressure relief valve is needed to make sure it is working order, it is the safety mechanism that prevents it from exploding if there is a buildup of pressure inside the tank.   
  • The Anode Rod: The anode rod attracts corrosive minerals, so the rod corrodes instead of the tank. By replacing it every 5 to 6 years, the tank won’t corrode as quickly. 
  • Tank Flushing: Once a year flushing the tank will remove mineral sediment build-up that rusts the tank. 

While this may all seem overwhelming, once you have a routine water heater maintenance in place, it will become second nature, like changing the HVAC filter. For your water heater maintenance in Chattanooga, TN, call 423-718-7342 today.
