I have been facing central heating low pressure on unvented hot water RM Cylinders but can't see any leak on the PRV, expansion vessels and plasterboard celling.
I have got unvented pressurized RM Cylinders hot water system with 27KW Worchester gas boiler with expansion vessels .
When central heating is on, with in 24 hours, the pressure on the RM Cylinders hot water system side ( no pressure gauge on the Worchester gas boiler ) is going to 0 bar once the system is cold/ideal.
When i notice 0 bar on the pressure gauge which is happening once the system is ideal/cold, i top up the pressure, it goes to 1 bat with in a second and then few mins to 1.5 bar.
I got gas engineer to look at PRV, expansion vessels, everything is fine.
so main problem is pressure goes to zero with in 24 hours of central heating on and system is ideal/cold.
secondly when i top up, the pressure goes to 1 bar in 2 seconds and then it takes about 3 min to 1.5 bar.
Do underfloor central heating pipes buried under cement concrete leak generally?
Does this indicate underfloor central heating pipe leaking?
The leak detection company is not offering no find no fee for central heating low pressure pipe leak.
i would appreciate any advise as to whether to proceed with leak detection.
would they be able to find underfloor central heating pipe leak?
