my boiler is loosing water pressure & stops the heating?
Once a week I have to use the tap on the boiler to build up the pressure til the gauge goes from 0 - 1 bar.
if I go higher than 1 bar. say to 2bar then the overflow pipe
on the boiler sprays out water when the heating comes on.
There does not appear to be a leak in any of the raidators
What would cause this problem?
Boiler is. Ferroli. Model.Modena 80E
