Had been having problem with low pressure. Lots of parts had been changed. PRV, plate heat exchanger, Main heat exchanger, gauge sensor. And engineer after Engineer had lots of visits still fail to solve the problem now they are saying it is leak in the pipes under the floor
I had been told by a student plumber to check if PRV is hot in operation while heating is on. And it is hot but the pipe further down is not.apparently that is a sign of fault to the PRV or expanssion vessel.is that right? Thanks for help
