My existing floor standing boiler has now died on me and I have now the
opportunity to buy and install a more efficient boiler. The problem is
that the house (1901 circa) has the original single pipe system (mild
steel pipe work) that is gravity fed and runs throughout the whole
house servicing 20 rads.This in itself seems to be a problem if, as per
building regs I go down the line of purchasing a condensing boiler, as
I believe there are a number of issues.
British Gas have a policy where buy they won't touch the system as far
as the installation of a condensing boiler is concerned and GASFORCE
quoted £10k to install a 65 kw commercial boiler (the new boiler would
be sited about 6ft from the old boiler) which to me seems a rip off.
My preference would be to for a condensing boiler if it can be
installed and provide the efficiency over a non - condensing boiler,
although I have yet to speak to a plumber who
can give consistent advice. Would it be better to go for a high
efficient gas boiler assuming I get an exception cert.
