Energy Efficiency With An Electric Tankless Water Heater

November 13, 2009 · Filed Under Plumbing 

Compared to our traditional water heaters, an electric tankless water heater only heats water when you need some.  These new water heaters are generally known as immediate 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 traditional water heater where the hot water is retained inside a tank, with the new tankless heater, hot water may only be produced when required. 

One of the best 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 faucet.  As to the normal water heater, where the water that is kept in the tank must 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 sort of electrical 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 example, if you intend to only use hot water in the loo or kitchen.  A central unit is larger than a point of use unit, so it’s best to discover a appropriate place to store the unit.  For a point of use water heater, it is often 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 to 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. 

Apart from being energy efficient, these water heaters can even last up to 20 years which shows how worth while purchasing this product is.
