Replacement Unit - Some Issues - Bought From CPO
This unit arrived timely but didn't come as I would have expect for a brand new component. It was in a different box (that didn't seem to be the original) with the temperature dial and the instruction booklet just thrown in. After installation it was evident that the temperature couldn't be changed due to a faulty rheostat. Also, one of the wiring harnesses wasn't even connected that was keeping the primary heater from even energizing. It was put in on a Saturday so no detailed technical assistance was available. We had to initially use it with minimally heated water at 95 degrees.

The following Monday I called Bosch's assistance line and they said that I would have to be in front of the unit with a voltmeter. That Friday I called back with voltmeter in hand and received very helpful troubleshooting advice that identified the issue. They told me how to bypass the heat sensor and run the unit on the highest temperature. They immediately sent me a new circuit board (which I knew was the culprit) that was easily installed.....problem solved.

Hopefully this was an isolated issue and I would recommend this unit.

is the out put of this heater enough for a 3 bedroom apartment
Dean on Jul 5, 2016
BEST ANSWER: The 7736503050 has a GPM of 2.0 at a 60 degree water temp rise. That means it will be able to supply water to a single shower if the water is being heated 60 degrees to meet your desired temp.Depending on location and ground water temp, this unit might suffice for your needs.
Good morning,
I'm trying to locate an electric tankless water heater to accommodate a cabin I'm building. It is a 640 Sq ft cabin with 2 bathrooms and dishwasher/kitchen sink. I'm completely new to tankless water heaters
.... trying to figure out if this 17kw unit will work for this cabin. Any help would be greatly appreciated.

Thanks in advance,
Michael on Jul 26, 2016
