Energy Efficiency With An Electric Tankless Water Heater

Compared to our traditional water heaters, an electric tankless water heater only heats water when you need some.  These new water heaters are popularly known as instantaneous or On Demand Water Heaters.  They have been in demand in the market place due to their energy saving efficiency and straightforward design.  Unlike with a normal water heater where the hot water is retained inside a tank, with the new tankless heater, hot water will only be produced when needed. 

One of the finest qualities of this product is being an energy saver.  When the tap for hot water is closed, this water heater doesn’t consume electricity unless you use the tap.  As to the standard water heater, where the water that is retained in the tank should be heated and re-heated to be used, not like the tankless water heater, which only uses electricity when hot water is required. 

In choosing 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 plan to only use hot water in the bathroom or kitchen.  A central unit is bigger than a point of use unit, so it is best to find a suitable place to store the unit.  For a point of use water heater, it is often small in size and can be fixed to walls to economize space. 

The principle of the way the hot water is produced is kind of the same as the concept 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 20 years which shows how worth while buying this product is.
