I just paid my plumber ( sorry, certified gas wrangling technical engineer ) what he paid for it.
I don't move in the correct circles at the correct times....well not often
Got some custom made architectural masonry made for home at a stupid price from a client. Also made me a name stone for my mates house. Only discounts I get are usually on clothing
Worcester or Vaillant are my beast of choice ( says he, with his ariston - 4 yrs on, and nary a problem)..
Best to ensure your new one is compliant with the control techniques used by the old boiler ( used to have a ravenheat....when replaced with the Ariston, I had to fart about with the switching controls........it wanted separate firing signals for the DHW and CH ( mind, it isn`t a combi - its a system boiler)
Thanks guys , looks like I'm sticking with Worcester then . I've had 25 years trouble free from this Worcester Combi , fitted by myself except the gas supply . I won't be fitting this one though.
