Boiler looses pressure slowly only when heating

2018-12-22 · OK, it's indeed the PRV: When the boiler fires up and starts burning gas, a few table-spoons of water spurts out of the pipe, but there is no long term dripping as the water is driven around the central heating system. Secondly, the pressure rises by half a bar to 1.5 bars; so it would seem the pressure vessel also needs to be pressured.

Sealed System Pressure Problems – Combi Boiler

First you must lose the pressure on the central heating water side by draining from a drain cock until the system pressure gauge (boiler gauge) shows zero. Don't use the 3 bar pressure relief valve to dump the pressure because, once operated, the seating may become contaminated and it may leak water through the safety pipe afterwards.

What is the safe pressure for a hot-water-heating

Most residential hot water heating systems run at 5-psi more than the pressure required to raise the water from the fill valve to the highest point in the system. In my Cape Cod house, with the boiler on the floor of my garage, the pressure gauge reads between 12- and 15-psi (the dial is too small to read more accurately than that).
