Facts You Probably Didn't Know About Your Water Heater

August 15, 2022

Water heaters have one purpose - to heat water to a certain temperature and then maintain that temperature until the power is shut off. Their convenience makes them perfect for everyday use. However, there are a few facts you probably didn't know about your water heater:


How Do They work?

A water heater consists of an anode and a cathode, which are connected to each other by an external current. The anode heats the cathode and causes electrons to flow through the circuit, creating a current that powers the heater. To ensure the water doesn't boil over, a temperature sensor in the heater measures how hot it is. The sensor shuts off the current and prevents accidents if it gets too hot. If your heater doesn’t work, you should ask water heater repair professionals to check this connection first.

Gas And Electric Water Heaters Work Differently

The primary difference is that an electric heater uses a thermostat to control the flow of hot water through the system. This means you don't have to worry about turning on and off your electric heater, as you do with a gas heater. Gas heaters operate best at temperatures between 50 and 100 degrees F, while electric models can be used anywhere from 60 to 240 degrees F.

Lifespan Of A Water Heater

The average lifespan of a water heater is about 10 to 15 years; however, the exact number depends on the type of heater and how often you use it.

Water Heaters Can Explode

Water heaters are designed to keep water hot and ready for use but can still burst into flames. The most common cause of a water heater explosion is a gas leak. Faulty plumbing or an insufficiently sized gas line can create a buildup of pressure in the tank, which can cause the tank to explode. Since these explosions are so dangerous, it's recommended that you call a licensed plumber immediately if you suspect you have a gas leak.

First Water Heaters

The first water heater was used in Pennsylvania. The concept was brought from Norway to the United States by Edwin Rudd. The invention was revolutionary because it allowed people to heat water electronically instead of relying on fireplaces or stoves.



Tankless water heaters are typically more expensive than traditional water heaters but can also be more reliable. Many homeowners choose to install tankless water heaters because they can save money on their monthly utility bills by not having to run high gas or electric bills.

Weather Conditions

If you live in a mild to hot climate and are looking for a source of heat, a heat pump water heater or solar water heater could be a good option for you.

Both heat pump water heaters and solar water heaters generate their heat. They are usually installed outside the home so they can generate additional energy during the day and store that energy in batteries.


Even though they seem like they're always working, a lot is going on in your water heater that you may be completely unaware of. It's almost like they have minds of their own. You should also perform regular maintenance on your water heater to ensure it's in the best shape possible. The more you know how it works, the better equipped you'll be to take care of it when it needs attention. We hope you enjoyed reading these facts about water heaters.


I believe in making the impossible possible because there’s no fun in giving up. Travel, design, fashion and current trends in the field of industrial construction are topics that I enjoy writing about.
