        Q:How many of these units are needed for 9 bedroom house?/ 5 bathrooms
        by|Oct 10, 2022
        1 Answer
        Answer This Question

        A:  Greetings, The number of units needed depends on where you are located. If the house is located up north or in the middle region where there is a colder groundwater temperature, two units will be needed. If the house is located in the south, one unit would work. Additionally, the unit in the link above is for Commercial use only and is not designed to be installed in Residential homes. The comparable Residential model water heater is RU199iP. Thank you!
