True thermostatically-controlled tankless water heater with full flow-based power modulation. Available in power range up to 10 KW (208/240 volt configuration). Excellent choice for point-of-use applications where flow rates or water pressure may vary due to multiple water demands or well pump pressure changes or where very low activation flow rates are required. Features digital temperature selector.
Stiebel Eltron Tempra Series Stiebel Eltron Tempra Series Tankless Water Heaters
Used mainly for whole house applications, these thermostatically-controlled tankless water heaters feature full flow-based power modulation and can be used for more demanding point-of-use applications where higher flow rates are required.

Features digital temperature selector.


Point of Use Tankless Water Heater Selection Guide

Water Heating Regions / Zones

The most important considerations when selecting a point-of-use tankless water heater are:

  • Water Flow Rate
  • Incoming Water temperature
  • Activation Flow Rate
The chart below will give you some guidelines as to the flow rates of common water demands. It is important to note that the flow rates of these applications will vary due to water pressure and other factors. Accordingly, you are encouraged to test you actual flow rate of your application for a more precise model determination.


Application
Flow Rate in
GPM at 60 PSI
Bathroom Vanity Sink Faucet 0.5 to 1.5 GPM
Kitchen Sink Faucet 1.0 to 2.2 GPM
Typical Shower 1.5 to 2.0 GPM (Max. 2.5 GPM)
Typical Bath Tub Faucet 2.0 to 3.0 GPM
Clothes Washer 1.5 to 3.0 GPM

Once you have determined the flow rate your require, use the map and chart below to determine which models are able to meet your flow rate needs based on your incoming water temperature. It is important to verify that the activation flow rate for the model selected is less than the flow rate of your application or the heater will not activate.
