Hi, I have a Worcester 28i junior boiler that has started to lose pressure, only when using the central heating. When using hot water I have no issue, however, when running the heating the pressure drops. Im looking for some ideas on what could be causing this. I have no sign of pipe leaks, although they could be hidden. Is it possible it could be the boiler, even though I see no water leaks?
Expansion issue so needs a gas safe engy to fix as the prv will need to be changed
Hi. I was hoping it would be something along those lines rather than a leak. With it only being when I used the heating I was convinced it was a pipe leak and currently see not water anywhere. Was worried it was hidden somewhere. Would I expect to see water coming from the over flow in this case or not? Thank you...
Maybe but only when the system is fully hot
Also, the pressure increases to 3 during the heating cycle. It did then come down again.
Which probably would the prv letting some out or it cooling down
Ok great...really hoping it wasn't a leak.
