I have got Valliant boiler and has started playing up since yesterday. I called the heating engineer and he told me that the heat exchanger has gone. I cant get hot water in the shower, unless I run it very slow. The price quoted was £180.00, is it right? What about the labour cost ? PLease help if this price is right. The number on the boiler is GW 634/0 I dont know if this makes sense. Hoping to hear from you soon.
Thank you
