I recently bled the towel radiator in upstairs bathroom.
Since doing this I have had system pressure loss problems. There does not appear to be any leaks, apart from the pressure relief as the system over pressures.
System fired up OK on first occurence after having bled radiator then repressurised via fill loop.(1.2bar)
System now over pressures (3bar +) after starting at 1.2 bar. Subsequently as system cools overnight pressure drops below 1.0 bar and fails to start in the morning.I presume this pressure loss is due to loss of water from the system via pressure relief valve.
I have to repressurise system to get the heating to run, but next morning the same problem occurs. Could the Expansion Vessel need repressurising?
Any answers as to the reason/s for this problem.
