Hi guys
Over the past couple of weeks I have had to top up the pressure in my hot water/central heating system every 3-4 days. I have access to most of the pipe work in the house and can find no evidence of a leak anywhere. I have bled the radiators. I would guess that I have to let the water into the expansion vessel for about 30 seconds each time. The boiler was installed in the cellar around 1980 and origanally was fed from a header tank in the loft. Around 15 years ago I replaced the header tank with an expansion vessel which is sited beside the boiler. There is no evidence of any water coming from the expansion vessel vent.
My guess is that there is a leak in the heating coil in the hot water cylinder, if this is the case how can I prove it?
I am thinking that if I turn off the cold head to the hot cylinder and turn on the hot taps I should have a slow flow and loose pressure from the expansion vessel. What do you guys think.
Thanks in advance.
