I've re-pressured my heating boiler, but it's gone right up to 2.5 bar, too high! So how can I get it back down to 1.5 or thereabouts? Many thanks.
Sounds like you have a steam boiler, I suggest you post the make and model of the boiler and control so you can get an accurate answer.These controls run on a differential,and cycle the burner on a call for heat from your thermostat.How many floors you have is also a factor.
