Choosing a back vented Combi Boiler with reasonable efficiency
 

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.

Ferroli F30 with a rear flue ( an extra that will enable the flue to come
from the rear of the boiler instead of the top ) with a flow rate of 12.5
litres per minute

The Glow Worm Condenser 30CXI is well thought out and uses stainless steel
heat exchanger. The ones I've installed have been no trouble. I can't see
there will be any problems in going up to the 35

And have a look at www.uselessenergy.org.uk for good prices on the Glow-Worm
condensers (I've just fitted one that I purchased through this scheme, and
have been very happy with it so far).

Thanks for the feedback - Unfortunately not a rear flued boiler - which
means a new hole in the wall. Nice cheap prices though, relatively. It's
a bit harder to justify not getting a condenser when they cost less =)
Just a little concerned about the longer-term costs of reliability, parts &
servicing over a standard combi..

Cheers
