What Size Tankless Water Heater Do I Need?

  • Transcript

    LESLIE: David in Missouri needs some help with a tankless water heater. What can we do for you?

    DAVID: Yes. I was wanting to find out where I could buy a tankless and what size I would need.

    TOM: Well, the answer depends on the number of bathrooms in the house, David. And all of the manufacturers of tankless offer sizing guides. For example, if you go to Rheem.com – R-h-e-e-m.com – they have a section of their website – they call it “Easy As 1-2-3 Tankless Selection for Homeowners.”

    LESLIE: Mm-hmm. It’s under their Best Fit Guide.

    TOM: How many bathrooms do you have?

    DAVID: It’d be two.

    TOM: Two? Alright. So that’s the smallest one. They call that the RTG-64 Series. And that should supply plenty of hot water for your house. And the nice thing about tankless is it essentially supplies an unlimited amount of hot water, so you’ll never run out.

    DAVID: If it makes any difference between well water or city water.

    TOM: No, it shouldn’t make any difference whatsoever whether you’re heating well water or city water. The tankless water heater will work just as well with both.

    DAVID: OK. Thank you.
