I had an Ideal Isar HE30 boiler fit nearly one year ago. About six weeks ago the system started to lose its pressure and would go to zero pressure over a 48 hour period. I topped up the system to 1.5 bar and bled all the rads. I checked all the rads and pipework in the loft for leaks with nothing to be seen.
The company who installed the boiler were called out twice. They have checked the boiler and visually checked the system pipework and rads for leaks. They are adamant the loss of pressure is in the system somewhere and not the fault of the boiler.
I have added a bottle of rad seal to the system to no avail.
The house is a 3 bed detached. The boiler is situated in the utility downstairs. There are no damp patches on any of the ceilings upstairs or downstairs and no damp patches on any of the walls. The dowbstairs is all concrete floors.
I think it is fair to assume that losing 1.5 bar of water pressure every 48 hours would give up some form of damp patch as it would be approx 5lts of water each time the pressure dropped to zero. This means over the last 6 weeks over 100lts of water has been lost from the system.
The pressure drops off whether the ch system is turned on or not. You can re-pressurise up to 1.5 bar, never have the heating on and 48 hours later the pressure will be zero.
I only have 3 weeks of the boiler warranty left and would appreciate any advice that would help me identify the fault.
Thanks
