Can someone please advise me on the following problem?
I have a Worcester CD30 SYSTEM boiler which is connected to the plumbing in an S configuration. Heating is pumped and hot water is pumped via 2 diverter valves. There is a radiator in the upstairs en suite which is part of the hot water circuit ie the radiator does not heat when central heating is on but does work when domestic hot water is on.
I have removed this radiator to fix new tiles behind it and to fit a ladder type radiator therefore I need to take off these closed valves and replace them and modify the pipework. Do I need to empty the whole system to do this or can I get away with emptying part of it?
You help would be much appreciated,
Thank you very much...
