Having said that, I have a feeling that this exemption thing has the
potential for abuse - i.e. if the customer doesnt want a condensing
boiler or the non-condensing one remains cheaper etc. the form gets
filled in. The wording is sufficiently loose in that the
householder only has to say that a possible location is not suitable
and the fitter signs off the paper. Nobody's going to pick it up
AFAICS.

Until few condensing boilers are sold and the Ministry starts to see why.


About 2006-7 by the time data is gathered.

It will be interesting to see what the vendors do. Presumably
condensing products will drop a bit in price as volumes increase.
Whether older non-condensers will increase in price as volume drops or
not because the return on development is already retrieved it's hard
to say.

The implication would seem to be that for replacements of wall mount
boilers that assuming they are on an outside wall that a condensing
replacement would have to happen, since a) no move of room and b)
likely to be on outside wall if present unit is oldish without fan
flue.

Replacements of floor standing units in existing location could also
not be exempt because if the points for a house plus long flue plus
condensate drain are added it comes to 890 for detached/semi/end
terrace or 940 for mid terrace. I guess that floor standing units
in a flat are not that common.

So it seems to only leave back burners after the above cases.

Clearly the points system has been contrived with various combinations
in mind to only exempt the corner cases - the numbers would be more
rounded if not.
