Vaillant VCW-sine 18 T3 W GC Code 47 044 01
I have had this now for about 20 years but recently when I draw Hot Water the system is heating the radiators at the same time. The Hot Water is not very hot. I read somewhere divertor valve, can anyone tell me the part number and how easy it is to change please. I also need to get a new piezo igniter as this stopped working a few years ago, fortunately the pilot never goes out. Can someone recommend a good site for parts ?
Thanks In Advance Milocoon
