I have a glow worm compact 100e combination boiler.
Everything runs fine until i put the central heating on, or rather turn it off!!
As the system cools down the pressure drops to zero. Sometimes boiler lockout light comes on. I re-pressurize it to 1.5 bar. Everything ok no loss of pressure, water warms up ok. I turn the thermostat up to switch central heating on pressure rises to approx 2.5 heating warms up. When i turn central heating off by turning thermostat down pressure drops. Every time i put central heating on i have to re-pressurize the system. If i do not put central heating on pressure remains the same. Any ideas?
