Tankless Water Heater by Stiebel Eltron ~ ~ Go Tankless Water Heaters

What is a tankless water heater?

Conventional water heaters heat water slowly and constantly throughout the day and store the heated water in a large tank so there is hot water available when you need it. Unfortunately, even with the best insulated tanks, much of the energy it uses to heat the water is slowly lost throughout the day.

How does an electric tankless water heater work?

When a hot water faucet is turned on, a flow sensor in the heater detects that the water is moving and turns on a bank of heating elements or modules. The water passes over the heating modules, usually in series, and exits the heater at the desired temperature. Since tankless water heaters do the entire job of a conventional tank-type water heater in just seconds, they require very high powered heating elements.

What else should you know about selecting an on demand water heater?

Selecting the right instantaneous water heater for your needs is a function of the technology as discussed above, the maximum flow rate of water you will demand, and your incoming water temperature. Applications which require higher flow rates and/or that are in areas of colder incoming water temperature (northerly regions), will require a more powerful model.
