Compared to our old fashioned water heaters, an electric tankless water heater only heats water when you need some. These new water heaters are commonly known as instantaneous or On Demand Water Heaters. They’ve been in demand in the market place due to their energy saving potency and easy design. Unlike with a conventional water heater where the hot water is kept within a tank, with the new tankless heater, hot water may simply be produced when required.
One of the finest 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 standard water heater, where the water that’s kept in the tank should be heated and re-heated to be used, unlike 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 intend to only use hot water in the toilet or kitchen. A central unit is bigger than a point of use unit, so it’s best to discover a suitable place to store the unit. For a point of use water heater, it is typically little in size and can be fixed to walls to economize space.
The principle of the way in which the hot water is produced is kind of the same as the concept 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.
Aside from being energy efficient, these water heaters can even last as long as twenty years which shows how worth while purchasing this product is.
