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

    • 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.
