Had the boiler service man (small local guy, not BGas) 'round the
other day to service the boiler. He said that the heat exchanger was
"getting thin in places" and would start to leak "within the year".
Given that the boiler concerned is about 20 years old he may be right.
I asked him what a replacement would cost. He said "about GBP1,100
installed". I nearly fell over with shock. That much for a 12kw
heating-only boiler ?
He then went on to explain that the local council is stupid enough to
subsidize boiler replacements to the tune of GBP200 and another £150
for upgrading "controls", so he suggested replacing the (perfectly
serviceable and newish) thermostat/programmer with another unit for
GBP30 and to pocket the difference of GBP120 in addition to the
GBP200, bringing the cost down to GBP780. (!)
My way of looking at it is this:
Boiler, 12kw: GBP350, tops.
Installation: Free, I can do that myself. Two water pipes, a gas
pipe, a flue, and a control circuit, how hard can it be ?
Professional commissioning and testing for leaks, just in case: GBP50
I think he was trying it on AND inflating the price by the amount of
subsidy to boot. Opinions please - what IS a realistic price for this
sort of thing ?
