Hi,

I'm looking to have a boiler replaced that's rather aged. To minimize
cost/disruption I'd like to source a roughly like-for-like rear vented (co-
axial) boiler, so it roughly slots into the current boilers location. Flow
rate should be high as poss on demand, not stored.

Glow-worm make a combi (35CI) that fits the bill but the efficiency is a
bit crap compared to others. Radiant make a nice boiler (RSF30) but not
back vented which means lowering pipes and a new hole etc. Documentation
on manufacturers websites is poor.

Not interested in condensers as longterm reliability is a bit crap.

Any make/model suggestions?

Many Thanks

Jimbob


p.s. first person to mention corgi/certified gets a slap, I know ta.
p.p.s have been to http://www.boilers.org.uk/ but it doesnt tell me venting
options.
