System Oil boiler has been loosing water through the pressure release valve so when system is cold the guage is showing pressure is too low and needs topped up.
(This shows to be the isolation valves for top up loop are fully shut off)
Expansion vessel was replaced with new one and still having same issue 😭
Pressure gauge showing pressure going up to 3 bar so looks like pressure release valve ok.
There is no automatic bypass but there are 2 towel radiators without thermostat valves.
Any ideas as to what could be happening here please? 🥺
