Evening people,
I have a Vaillant Vuw 242E/282E. The hot water only works when the heating is switched on.
I have rung up a boiler engineer (the same person whom fixed this problem 2 years ago) He tells me it's a Valve that has gone.
The price he gave me was 120pounds for a reconditioned part OR
190pounds for a new part both with ONLY 1 years guarantee.I am quite a competent guy and am prepared to fix my boiler myself. Can someone tell me what is actually wrong with the boiler and what needs changing.
reading up on threads some people suggest diverter valve or diaphram and a quick search for part prices tells me my boiler engineer is ripping me off!
please help!
