Hi,
I have a problem with the above boiler losing pressure.
There are definitely no leaks on the rads or pipe work, although some pipes are buried under concrete (not the best I know).
When the boiler is on its fine, all rads red hot and water hot when used.
The problems I've found are that the PRV is constantly leaking with a drip but also a flow of water when the boiler turns off after heating the rads.
The other night I left the boiler and didn't put the heating on, the boiler was at 1.6bar and left overnight it fell to 0.6bar without any use. However if the heating is on before going to bed the boiler falls below 0.5bar which stops it from working.
I'm hoping its just a replacement PRV job...
Any thoughts?
Cheers
