Energy Efficiency With An Electric Tankless Water Heater

Compared to our old fashioned water heaters, an electric tankless water heater only heats water when you want some.  These new water heaters are popularly known as instantaneous or On Demand Water Heaters.  They’ve been in demand in the market due to their energy saving potency and easy design.  Unlike with a conventional water heater where the hot water is retained within a tank, with the new tankless heater, hot water may only be produced when needed. 

One of the best qualities of this product is being an energy saver.  When the faucet for hot water is closed, this water heater doesn’t consume electricity unless you use the faucet.  As to the traditional water heater, where the water that’s retained in the tank must be heated and re-heated for use, unlike the tankless water heater, which only uses electricity when hot water is needed. 

In selecting any kind of electric tankless water heater, you can select between a central unit, where all points of water supply can be supplied with hot water, or a point of use water heater, for instance, if you intend to only use hot water in the toilet or kitchen.  A central unit is bigger than a point of use unit, so it is best to get a suitable place to store the unit.  For a point of use water heater, it is sometimes tiny in size and can be fixed to walls to economize space. 

The principle of the way the hot water is produced is sort of the same as the idea of gas units.  When you try and open your faucet, cold water will run into the tankless water heater and then the cold water triggers the heat exchanger in the water heater to turn on. 

Aside from being energy efficient, these water heaters can even last up to twenty years which shows how worth while buying this product is.
