Hi hope someone can help
we have just bought a house that has a ferroli optima 901 combi boiler which works perfectly.
However, one of the thermostatic radiator valves is broken and needs replacing and I need to drain the system, replace valve and refil / re pressurise system.
I have all of boiler instructions but this is our first combi and I dont want to break it (ie no heating in winter) (the broken valve is set to hot)
please can anyone help
thanks in advance
David
