Why You Should Switch From a Tank-Type To a Tankless Electric Water Heater

The benefits associated with a tankless water heater outweigh the cons.

Most of us have been in a situation where you are taking a hot shower and your water instantly turns cold.

The reason tankless water heaters are called instantaneous heaters is that they provide you with a continuous flow of hot water.

You never have to worry about the hot water you had in your tank electric heater running out.

If you have several people living in your household and sometimes the demand for hot water is high.

Installing several tankless electric heaters is the best solution to ensure that no one has to waste their time waiting for their water to shower to become hot.

Tankless electric water heaters are easy to install and can be fixed in very tiny spaces under your sink by just mounting to a wall.

Most of them only require two screws and this is something you can do by yourself.

The only time they use energy is when you have hot water running from your outlet.

They conserve energy that is used in tank-type heaters to maintain the temperature of the stored water while it is waiting to be used.

Technology has helped improve tankless water heaters so that they have their safety measures such as automatic power-off when not in use, anti-splash protection, and leakage protection that help avoid energy loss and tragedies.

Imagine coming back from work in the evening only to find your house flooded with water.

When you have a tank in your house and it malfunctions, this is a risk you face.

Tankless water heaters are slightly expensive than tank-type heaters but they are worth the value.

If well installed and maintained, tankless water heaters have a very long life span.

Final Thoughts

One 110V plug in tankless water heater is not enough for a household with several showers and several sinks which are sometimes used at the same time.

They are not powerful enough to heat a lot of water for all these uses at once.

But, installing several of them may be for each sink and shower is good enough and you will never run out of hot water provided you don’t run out of electricity.

They are fast, efficient, water and energy-saving, and non-pollutant.

Most of these types of heaters have various safety measures in place so you do not expect to have any incidents wherever you choose to install them.

The only challenge you might face with these heaters is during installation.

You may have to invite a plumber or electrician to your place but when everything is set up, you will never run out of hot water for a very long time.
