Hi
Our boiler has been fine for a couple of years & now all of a sudden the water pressure drops to nothing every day. The pressure remains up when the heating is on but as soon as the heating goes off the pressure drops to nothing. We have no leaks on the boiler & no leaks upstairs as the ceilings would be wet but cannot yet investigate for leaks downstairs as the pipes are under a sealed wooden floor!!!!! We want to eliminate all other possibilities before we lift the wooden floor as a last resort. Anyone got any advice?? please
Are you referring to the pressure in your boiler? If so the pressure should rise when the C.H is on and drop back when it is off.
If your boiler is empty of water or your C.H has developed an air lock in the piping, the pressure will be nil, your boiler will not work, you will have no C.H or hot water and your boiler will alert you of this by sounding a continuous alarm.
Why not have your boiler checked out by a competent heating engineer who should be able to advise you of any problems and rectify them for you before you go to the expense of ripping up your floor?
