This is silly. There is no way that condensing boiler are double the
price.


Its an Ideal Mexico Super CF4140 - 140,000 BTU - 41kw £872


Poor choice. The SEDBUK seasonal efficiency figure for this one is
78.6%. In other words, it only *just* scrapes into the minimum legal
requirements for efficiency according to the building regulations.
Fairly shortly, the minimum will be increased so this type of product
will be off the market and is probably why the price per kW is
relatively low. The manufacturers, knowing that the lifetime is
limited, are getting what they can for the remainder of its (short)
market lifetime. As far as I can see, it isn't on their web site any
more, so that should provide a clue.

Also, note that you are not comparing apples with apples. These
Ideal products are basic, non-system boilers and do not have a pump.
This particular model is also conventional flue. For a new
installation, this does not really make sense because of the need to
provide appropriate room ventilation (= cold air from outside) and the
likelhood to have to buy a flue system to go with it, pushing up the
price.


v
Keston C55 (55Kw) £ 1,548.89
or the C40 (40Kw) at £ 1,360.90


Both of these products come in at at around 90% seasonal efficiency,
include a pump and can work with cheap plastic waste pipe as a flue.

All of this is before the difference in energy saving is taken into
account.



(Prices I've got from pumbworld which don't correspond to the prices quoted
in the installation which are up by about 10-20% which makes the gap bigger)
