its the right control heating temperature goes to a red light if we turn it straight up to the auto ,we have to have it turned down so the rads come on about hand hot temperature
hi dont know if any one can help.Having probs with boiler works fine when the temperature is turned down low but as soon as we turn it up to the auto position it switches of .We switch it of at the wall turn temperature down again turn on and it runs fine any ideas?
pressure seems fine if not a little high it sounds like air in the boiler and it trying to get the air out it has an automatic air release valve no leaks anywhere could it be an internal leak in the boiler.
have got a vokera compact combi boiler water pressure keeps rising up to 3 bars .We drain water to lower it but a few hours later its the same.There is no air in the radiators.Although we have drained water from the system(lots of) how come the system isnt empty by now can anybody help
