Tankless Electric Water Heaters

Tankless electric water heaters are gaining more and more popularity on the market lately. The system is said to be reliable due to its ability to supply unlimited amounts of hot water.
But is that true? How about the other benefits and drawbacks of the system? Is this the right choice for you to install in your home?

The answer to that question depends on your family’s needs and the condition of your house. Here are some factors that you need to consider:

Water Supply

A tankless system is superior to a storage system because the hot water supply is generated as requested. That means you can have a very long, hot shower without worrying about running out of hot water in the middle.

However, the water temperature will most likely be inconsistent. Once every few minutes, you may notice the temperature fluctuate between cold and scorching hot, especially if multiple outlets are running at the same time.

If you need steady, lukewarm water, an electric tankless system might not be satisfying for you. In addition, your hot water supply will be completely unavailable during a power outage.


Electric tankless water heaters are 99% energy-efficient, which is higher than any other water heating system. Thus, it is the best option you have for switching to a greener lifestyle.

Moreover, you will be able to lower your monthly energy bill because you will pay only based on how much hot water you use. Another economical benefit from this system is the unit’s long life expectancy, which is up to 20 years.

The only thing you need to worry about is the upfront cost. Some people may not be able to pay the initial price because the units are around three times more expensive than a conventional water heater.


A tankless system is convenient because you don’t need to sacrifice a lot of space in your house like you would with a tanked system.

This is a huge relief for people with small houses. However, the system requires a specific wiring and circuit breaker. If your home’s electrical system is not ready, you might need to hire a technician first to set it up.


One of the problems with tank-style water heaters is that the hot water may cause the inner layer of the tank to corrode. Some amount of rust may get carried along by the flowing water and come out of your faucet.

This will irritate your skin if exposed to it, and it could cause other health issues if you drink it. A tankless system, on the other hand, poss no risk of corrosion.

Choosing a water heating system requires mature consideration of the pros and cons so you know what to expect and watch out for. To give you a clearer insight, you might also need to check out other types of water heater systems as well.

If you end up choosing an electric tankless water heater, make sure to only allow a certified technician to install it in your home.
