I have a Valliant VCW Sine Boiler and am having problems with the hot water. I have read all the posts relating to fault finding but no luck. Basically, I do not get any hot water when the heating is on. Any ideas? I have replaced the diaphram in the water section and looked at the flow swtich. These seem to be working, but not hot water!!!!
