Questions & Answers

I am installing a floor hydronic heating system in a studio of 500 sq. ft. It will be heavily insulated in 16 inch joist width. I plan to run the water through 1/2 inch pex at about 115 deg. F. Would the Bosch US12 suffice?Thanks so much, Paul

Will this unit furnish enough hot water for an energy star rated dishwasher?

by Timothy M. on 02-27-2013

From the research I did it seems this unit would work fine with that dishwasher. I will provide the Bosch phone number for you for more technical support. Tel: 1-800-798-8161

We ordered Bosch US12 to be dedicated to our new Jacuzzi tub 66" x 42". Our initial intension was to feed with our hot water so when we ran out the heater would kick in. We just received it and the installation instructions says NOT to feed it with HOT water. Will this heater be okay to feed only our tub? Our home hot water heater doesn't have enough capacity to fill our tub

This is correct, do not connect the Bosch Powerstream to a Hot line, as it is not designed for this. However, you can always connect the Powerstream to a cold line. Once you run out of hot water from your tank heater, you can initiate the secodary heater from the other line without needing to worry about feeding hot water into the Powerstream unit.
