Hi Tony thanks for the reply. I've downloaded the manual and have been ploughing through it to try to work out what's going on! Is it the main circuit flow switch that you told me to check? If so then I saw the plumber test it already and nothing happened when he pressed the switch - the...

Hi thanks for the reply tony. Plumber came today but couldn't fix the issue. He confirmed that the main flow switch was working (think that's the same as the pump proving pressure unit you mentioned). He said that the hot water wouldn't have worked if the switch wasn't working. He also...

sorry - here's what I'm doing: 1) Boiler set to provide heating and hot water (think it's winter mode) 2) Heating doesn't come on (even if radiators are cold) 3) Open tap and get hot water from it but this also gets the central heating working! 4) Heating seems to work fine for some time...

Hi Tony sorry for not being clear enough but I did mean just that as turning on the hot tap seems to kick the boiler into action. The central heating then seems to work - all the radiators come on and the temperature gauge keeps cycling - starting at about 50 degrees (when you hear a click...

thanks for the reply. Yes it would look like that(!) but to be fair on him there have been a number of issues with the boiler! The boiler and central heating system had a load of rubbish in it, so doing the flush and de-scale were probably worthwhile and he showed me the diaphragms that he...

Hi I've got a biasi 24s boiler which has an intermittent problem with the central heating (the hot water works fine). So far have had the diaphragms changed, main heat exchanger de-scaled and whole system power flushed. Plumber is now not sure what the problem can be and the heating seems...
