When I went to switch the heating on, I noticed on the boiler that the dial on the pressure reading wasn't in the 'green zone', it was below it. is this normal?
Not sure where the green zone starts, but, assuming your boiler is hot water, and not steam, the water regulators are typically set to maintain 12psi....and should be raised accordingly when the boiler is in the basement of a multi story building. You may want to make sure the water supply valve is on, and from there the feed valve / regulator should take it from there. If water is on, and you're confident that the gauge reads accurately, it'd be best to call a pro to look at it. An improperly serviced boiler can create some real hazards. Good luck
