Questions & Answers

  • Q:

    "I live alone in a 2 bath house, dont use the dishwasher, will this be enough for my kitchen sink and shower?"

    • A:

      Hi pewterlady123, this tankless water heater has a flow rate of 4 GPM and the typical shower uses 2 GPM and the typical kitchen sink uses 1.5 GPM. The heater may work for you, but we would recommend talking to a professional plumber to ensure compatibility. I hope this helps, thanks for shopping with us.

  • Q:

    "What is the wate temp rise from 70 degree water at a 2GPM flow rate?"

    • A:

      Hello btfishalot, we have provided the following link to help you determine the flow rate to 70 degrees. There are some tables that have you review your location for the groundwater temperatures. I hope this helps you! Thank you for shopping with us.
