Hi,
Recently over the past few weeks our boiler keeps going from hot water to cold water. However sometimes it takes a few minutes to go cold then hot.
Sometimes it works for 30minutes. And sometimes it goes cold instantly and doesnt go warm again for a while.
During this process sometimes the boiler makes clicking/banging noises.
We have had a few plumbers around, they dont seem to know whats wrong?
Does anyone know what needs replacing?
Central heating seems to work fine.
Also the pressure was very low 0ish. Then I turned some vavle to increase it to 1.5bar.
