Hi. I have a Hydro Therm HK-84 Kickspace heater that I bought for my kitchen. When I got it home, I realized that it had a 1/2" inlet and outlet on it. My house has a 3/4" system installed. Do I need to run it inline with my system and only get the flowrate of a 1/2" pipe or can I put a diverter valve on it to allow the same flow rate as before? Thanks
