Is An Electric Water Heater Silent?

Yes. It’s almost silent, with a very low hum, so you are likely to hear it even if you are asleep. There is no noise at the start of the heating process, which makes it perfect for those who love to sleep in. There is a timer that will automatically turn it off if someone forgets and leaves their water heater on all day.

The biggest complication with this water heater is that it looks incredibly cheap. It gives a poor impression, and I have seen people even laugh at it when they see it.

However, if you are sure that you will not have to use it often, there is no reason you should not buy the lowest cost option.

The best thing about this type of water heater is that its performance is very good, and it stays cool throughout the heating process. As a result, it does not break down easily.

The main problem I have with this water heater is the manual. It is a very complex model that just no one can use.

If you are not mechanically inclined, I advise you to stay away from this product. Otherwise, you risk ruining it and getting a big headache that will cost you hundreds of dollars to repair.

This product is very affordable, but do not expect it to work 100%. Something will likely go wrong if you assemble it yourself and do not know what you are doing.

Otherwise, this is one of the best water heaters on the market. For this reason, I cannot say anything bad about it.

Do You Need To Bleed A Hot Water Tank?

A hot water tank is a cylinder (or sometimes cone-shaped) container used to store hot water so that you can heat it whenever needed.

When you turn on your hot water faucet at the kitchen sink, it’s easy to forget that the water you’re using is probably from the tank in a basement or garage.

Most tanks comprise steel and concrete, with insulation and foam to keep heat inside for as long as possible.

Yes. You need to bleed a hot water tank, whether or not the water is hot.

If you don’t bleed the tank, it will dry out, and your tank can become filled with minerals that could clog your pipes.

You also need to bleed a hot water tank if there’s been a change in the water pressure to the house, such as during a storm or power outage (check with your water company).

You should also set up an annual maintenance plan for your hot water system so it doesn’t dry out.

It’s a very simple procedure that takes only a minute or two to complete.

Before you begin, go to the lowest faucet in your house and open it up. Open the drain, too.

Also, make sure there’s enough water in the tank to cover the ball and allow it to float up and down freely. If it needs more water, run the hot water until there’s enough.

The proper way to bleed a tank is to:

  • Open the drain valve, which you will find at the bottom of the water heater or tank.
  • Open the highest faucet and let the water flow until you see a continuous stream of water gushing out of the end of the faucet.
  • Open a second faucet and run it until you see continuous streamflow from that faucet, as well.
  • If you aren’t sure about this step, tape a piece of paper to the side of the tank and move it around until you see the stream coming from it or both faucets.

When you see water coming from both faucets, close both drain valves and open them again when finished.

Repeat this procedure several times to bleed all the air out of the system.

Are Electric Water Heaters FVIR?

Yes. Using an electric water heater, you can save up to 40% on energy bills-for starters. It’s time to take the plunge and try this hot new trend in heating systems.

You may find many other benefits in using an electric water heater. You won’t smell foul smells like when you leave a gas heater on because they’re odorless and environmentally friendly.

The heaters help prolong the life expectancy of your home appliances too. Also, you will save money, but you’ll also reduce your carbon footprint.

Thus, before spending more money on a new electric water heater, make sure your current one is FVIR.

You can determine whether your electric water heater is FVIR by adding the letters to the end of the model number.

For example, a tankless water heater model Rheem WDH-36N-PK, 36,000 BTU, or a tankless electric water heater model Rheem WFH-40N-PK, which is 40,000 BTUs, then you have an FVIR electric water heater.

For an electric water heater that doesn’t have a model number, you can still determine if it’s FVIR by calculating the BTUs for each gallon of water that the heater can heat.

Just divide the total BTUs of the whole tank (usually found at the top of your gas statistics labeled as your “tank”) by 16. This will give you your approximate gallons per hour.

Multiply that two times and add 20% to get your approximate gallons per hour. So, for example, if your water heater holds 100 gallons and it is FVIR, it can heat around 200 gallons of water per hour.

What Do All FVIR Tanks Have In Common?

FVIR tanks boast many common things that include:

  1. Thermal cutoff switch
  2. Pressure relief valves
  3. Non-opening fill caps
  4. Non-opening vent caps
  5. Body materials such as steel, aluminum, or stainless steel alloys
  6. Piston storage, or piston storage area
  7. Release mechanisms such as a fuse plug
  8. A large fill line and vent line with the release mechanism
  9. An estimated volume, internal and external measurement marks, and working pressure(s)
  10. A warning label on the fill cap to not overfill the tank
  11. A pressure gauge for filling only, marked in bar and Psi if applicable (Kgf/cm²)
  12. Depending on the tank, they may or may not have a single large fill and vent point
  13. Depending on the required capacity of the tank, tanks may or may not have a large opening in the cover to fill them
  14. Depending on what material they comprise, tanks may or may not be lightweight.
  15. FVIR tanks have different sizes and capacities than water storage tanks and propane barbecue cylinders used for backup power generators, and other alternative fuel uses for emergencies.
  16. They are waterproof and resistant to chemicals and water.

Do You Need Water Heater Expansion Tanks?

Yes. There are two reasons for this in most cases.

The expansion tank prevents the hot water from building up pressure inside the water heater and spraying out from around openings that may exist in its base.

The second reason is to reduce a possible risk of carbon monoxide poisoning, which may result if there isn’t a fully vented outlet through which air can enter when it isn’t needed.

Water heater design requirements vary, so first, confirm with your home’s manufacturer or local building code experts what they recommend depending on local standards.

Some jurisdictions only require insulation of water heaters, so check your local building codes for details.

If there is the involvement of a commercial installation, such as a hotel or other public facility, you may need permits from the appropriate agencies.

From the design standpoint, many municipalities require a minimum size of the water heater tanks, usually four gallons per faucet, to meet the “safe maximum” requirement of 100 gallons of heating capacity in all homes.

The exact allowable maximum depends on the local codes and location’s water pressure, but the national average is 75 gallons per faucet.

This low capacity limit prevents scalding in homes with several faucets and showers or bathtubs running simultaneously.

Also, some code jurisdictions will require larger tanks of 10 gallons per faucet for homes with spa-like showers having multiple shower-heads.

Do You Need To Drain All Water Heaters?

Yes. Water heaters need draining for regular maintenance and to prevent damage.This includes in-line water heaters, tankless water heaters, and electric pumps that sit on top of your main plumbing system.

If you cannot drain the tank, the best option is to contact a plumber.

They will drain it for you, inspect your system, and advise how often you should drain it, which parts of your home need more attention, and what fixes you need to make.

A warm water heater runs hotter than a cold water one, so drain the heater to prevent scale from gathering in your pipes and causing leaks.

A plumber will also be able to tell you whether this is necessary for your particular model. You can use a “heat exchanger” hose if you drain your water heater yourself.

This hose connects to your hot and cold water supply lines and will cause a siphon action as the water passes through it.

If your tank has an automatic drain, consider leaving it in place because the heat exchanger will cause the release of some hot water back into the tank before the siphon can be complete.

This is a good idea to do annually, but you should do it more often if you’ve had any water damage or your system loses hot water too quickly.

Once the tank is empty, drain the valve at the bottom of your water heater to prevent further rusting.

If your tank has no drain valve, use a long string and wrap up the ends so they won’t cause damage when they come loose.

Can You Hear An Electric Water Heater Run?

Yes. An electric water heater will have a heating element and fan that runs when you set the thermostat to a power level higher than the temperature of the water.

Ensure there are no leaks, don’t have a gas system, and set your thermostat correctly before calling for service.

The noise from an electric water heater may be inaudible outside the room but can be quite loud inside.

It usually stops running once it has heated up enough or when it’s time to cool down again. If your water heater is often running, you should have it checked for leaks or for safety issues.

You might notice a buzzing sound from your water heater when the heating element is on and the fan is running.

A humming noise means that a heating element isn’t operating properly, which can mean it will need replacement.

Green Living Tips: Water Heater Noises

If you hear a slight clicking or tapping coming from your water heater, turn off the power immediately and do not use any hot water until you resolve the problem.

Don’t forget to turn off the power when you leave your house for a few hours or even a day. It will help out with your utility costs.

You may not need to replace the appliances that make this noise but do recognize that they have troubles from time to time, and thus, it’s wise to fix them at the earliest opportunity.

Can An Expansion Tank Explode?

Yes. An expansion tank can explode if the relief valve develops problems, if the fluid gets too hot, or if it’s overfilled or undersized.Shut off the water supply if you see these symptoms and contact a plumber immediately.

You can find expansion tanks outside bathroom fixtures and dishwashers to control pressure.

They’re really easy to identify: they’re usually cylindrical, have a pipe coming out of the top with a lever for manual release, and bear the mark “expansion tank” on the side.

Many plumbers will tell you that expansion tanks are a bad idea and that you can get by without one. They’re saying they’re unsure how to size them properly or aren’t comfortable with the installation.

In most cases, the correct expansion tank will fix your problem without any hassle.

An expansion tank aims to prevent pipes from bursting when water temperature changes suddenly or pressure builds up in the system.

For instance, if you’re using a 25 Gallon tank, the pressure can build up to over 300 Psi without bursting your pipes.

Instead of calling a plumber when you suddenly have high water pressure, which is only normal yearly at certain times, you can adjust the spring in the expansion tank.

It can be catastrophic if a spring breaks inside an expansion tank. The pressure will increase inside the tank until it finally bursts and causes expensive damage.

The first step in sizing an expansion tank is determining when the plumbing runs and the water pressure at normal operating temperature. Then you will know what it takes to pressurize your system.

If the plumbing runs high at all times, you need to do a full flush before starting a new job to undo any potential damage that may have occurred during the previous year of normal use.

Also, ensure no holes in your pipes (which you should check and repair as needed).

Since pressure is the only limiting factor in an expansion tank, make sure that the tank is not too small or too large.

The problem with too large tanks is that any trapped air will still cause pressure to build up further even if you flush your system.

As a result, the water pressure will continue to increase month after month until it finally bursts your pipes and causes damage.

Are Electric Water Heaters Quieter Than Gas?

Yes. Electric water heaters are quieter than gas because they have no combustion. However, an electric water heater with a gas expansion tank will make noise because the gas expands to the burner coils to heat the water.

Electric water heaters are typically quieter than gas hot water heating systems.

Electric water heaters have no combustion and thus produce zero emissions. The only noise produced by an electric water heater is from the pump if it has one.

Many heaters have a pump that circulates water through the unit to help remove impurities and heat the water more quickly. Pumps are usually quiet, but some are louder than others.

Gas hot water heating systems perform all their functions through gas combustion, producing combustion gases and a hot water heating system noise.

The biggest concern with noise from gas heating systems is from the expansion tank. Like a pressure cooker, the expansion tank holds water that expands when heated.

As the water expands inside the tank, it can produce a loud noise. Some expansion tanks are louder than others, but there is not much that you can do to make them quieter.

Most water heaters are fairly quiet regardless of type. However, if you have a gas-based water heater with an expansion tank, it can make noise.

Conclusion

Electric water heaters are quieter since there is no combustion. However, if you have a gas-based water heater with an expansion tank, it will make noise.

You may solve the problem yourself without calling a professional by ensuring you size the tank properly. Also, ensure you flush whenever you run water through your pipes.

I don't like to call myself a blogger; they are very analytical, do email marketing, and know all SEO stuff. I faced many questions from customers about different products, and there was hardly any help on the internet. After learning all the things about these products as a manager the hard way, I decided to start a blog and help other people.
