    Q:I have a Bosh 27kw 220/240; CAT #45557721; serial # 719C800100. This unit has been working fine for the main house of 3,668 sq. feet. I am adding a "suite" in the basement of roughly 770 sq. ft. Will this unit carry this extra area?

    Q:I am installing a new build home with a massive custom shower. 2 regular heads, 1 rain head, 3 handhelds and 12 body sprays. obviously not all will run at the same time. I am adding a pump to increase the pressure do I daisy chain 2 or is 1 enough.

    Answer This Question

    A:  Jason, Model WH27 requires a Cold input, so daisy chaining is not the right installation option. You can still use multiple units but the Hot water piping to the shower heads will be independent for each heater. As for the capacity, please see the "Additional Resources" section on the product page and go to "Installations Assembly". Then go to page 4 and see the chart "Water Heating Capacity". Here you will need to know your maximum GPM for each unit and your incoming water temperature to calculate the capacity for each unit.

        Product is compact, clean and easy to install. The digital thermometer is nice to have to get just the right temp. So far it seems to work fantastic.

        The new water heater did not work, and I incurred several hundred dollars in plumbing costs trying to troubleshoot why it wasn't working.
