Am baffled by my boiler pressure and wonder whether some kind soul could advice.
I have a Worcester Bosch Greenstar Condensing boiler. 6years old. last serviced 3 years ago.
There was no water coming out of any of the hot taps last week and an engineer replaced the expansion vessel, temperature relieve valve and replaced the monoblock reducing and safety valve(?).
Since then the pressure reading has gone a bit bonkers, it reads zero even after 30 mins of heating. When I switch off the heating and hot water it goes back up to just under 1 for a bit and then it drops again. (the engineer left it at 1)
I have searched the whole house for leaks and can't find anything.
The boiler has always needed a bit of topping up, say every 4/5 months but I really don't know what to do now.
From my amateur research online it could be an expansion issue in the boiler or a valve issue, or a leak (but the pressure readings are quite erratic, I'm not sure this is it).
Any advice very gratefully received?
