I have a Burnham Revolution boiler which has an internal variable speed pump. It seems that once a year this pump stops working. The previous years just shutting down the system for a few hours (about 3) would "fix" it.
I was wondering how to troubleshoot that pump, since it also could be the mixing sensor or the control board.
The symptom: the water temperature coming out of the boiler is at most 130F. Yet the internal temperature sensor indicates 170F. It seems as if the heat exchange between the internal circuit and the outgoing is not working well, which I think is because of the build in variable speed pump.
Would these be easy to replace? And where would I get one?
Any suggestions would be appreciated!!!
