A condensing boiler with its lower flue gas temperature is much more

possibility I might be dropping smelly fumes into his garden (and over
his washing line). For, perhaps GBP20 pa when I won't break even on
the boiler costs for 10yrs. NO.

Hi,

Why not make a stainless flue gas heat exchanger for a conventional
oil boiler, and use the low grade heat for UFH/HRV/DHW
preheat/kickspace heater?

I'd expect oil to increase in price over inflation in the next 10
years, this will speed up the payback on any up front investment.
