I have looked at most threads on problems similar to mine but not sure if it's the same problem
Ok so I got to put heating on and it isn't working so I go look at the boiler, red light is on I check the pressure gauge and it's in the red, so I top up the system using he filling loop till it gets to 1.5 bar reset the boiler and it begins to work, later on I go out side and the over flow is dripping brown fluid,
I go look at the boiler and the pressure is around 2.5 bar so I open radiator valve to release down to 1.5 bar, hot water is fine and heating fine,
Next morning heating should have come on via the timer and the rads are cold so I go look at the boiler again, pressure in red and red light on, so I repeat above to get it going all the same things happen water dripping and increase in pressure when hot,
Been doing this now for a few weeks and it's driving me nuts, when I leave the heating on 24h 7 days it's all fine once I relieve the pressure down to under 2 bar, water stops dripping out overflow and everything works as it should,
I checked the expansion vessel and it's full of air no water, and reading 14psi
I'm going to order a psv any tips on changing this would be good,
Heat exchanger may be faulty but not sure as to why the pressure rises then once I stabilise the pressure after it's initially gone up it all works fine if something was leaking into the system then why once I stabilise it does it stay steady at that pressure and not continue to rise?
