Electric tankless water heaters are one of two types of tankless water heaters, the other being gas tankless water heaters. A tankless water heater is a compact appliance that provides hot water when needed without storing the water. Profitability, easy installation, energy efficiency, less maintenance, longer equipment life and unlimited hot water supply are the main advantages. Gas, propane, and electricity are the main sources of heat for tankless water heaters.
Tankless electric water heater usually has more than one heating element and these elements provide high heat output. Tankless electric water heaters require less energy. Plus, they don’t store water and instantly heat it up as it flows through the unit.
Electric tankless water heaters are available in two different models: flow controlled and thermostatic. Flow control electric tankless water heaters are designed in such a way that they can only be fed with cold water. But on the other hand, electric tankless water heaters with thermostat function can be fed with hot and cold water, and keep the water temperature within a safe limit.
A range of electric tankless water heaters along with the most sophisticated technology and advanced features are available in the market today. Some of them are Ariston hot water heaters, the PowerStar AE125 electric tankless whole house water heater that provides up to 3.5 gallons per minute and the PowerStar AE12, an electric tankless water heater with sink and thermostatic control. All these electric tankless water heaters are used in both commercial and residential settings. In a residential setting, they are ideal for kitchen sinks and laundry areas.
The disadvantages of electric tankless water heaters are that they require a lot of electrical energy. Furthermore, they are unable to produce high flow rates, resulting in a lack of adequate water supply for multiple simultaneous purposes.
