I have zero pressure in the boiler. Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

I took a radiator off the wall to decorate; now it is not filling up and there is no hot water and the pressure on the boiler is zero and is not lit. It is a combi boiler. I put the radiator back on exactly in reverse. Help.

The answer is in the question - the boiler pressure is on 0,

Re-pressurise the system and the boiler will work. The pressure gauge should be between 1.0 and 1.5 bar.

Re-pressurising is fairly easy, but there are different ways of doing it depending on the boiler, read boiler manual.
