Electric Tankless Water Heaters

To determine if an Electric Water heater is for you:

Temperature Rise: Subtract the incoming water temperature from your desired output temperature. 

Flow Rate: List the number of hot water devices you expect to use at any one time. Then, add up their flow rates (gallons per minute). This is the desired flow rate you'll want for the demand water heater. 

Therefore, to size a demand water heater, you need to determine the flow rate and the temperature rise you'll need for its application 

If it will not produce the desired flow rate and temperature rise to get to a comfortable hot water handwashing temp. of 105°F, then choose another model with more kW and amps, and ensure that you can supply it with the required electrical capacity.

 

Determining which tankless Electric Water Heater can be a difficult choose. Visit our blog to select a model that will suit your needs.
