Boilers are amongst the worst offenders when it comes to energy wasters in
your home. Boilers alone account for up to a third of all domestic CO2
emissions. If you don?t think your boiler should get away with it any
longer, then read on. As the current lifespan of a boiler is 10-15 years,
making the wrong decision about what boiler to have really could mean a life
sentence of wasting money and time and damaging the environment.

A heating system that uses a high efficiency condensing boiler and with the
correct heating controls can save as much as 40% on your fuel bills. It
really is time to shop your old boiler.

At an alleged saving of £120 a year, it would
take 16 years to recoup my investment.

Your boiler will not last that long.

And nor will the new one, from the very data you quote from! What's
the point in recommending someone fit a boiler expected to last 10-15
years when the payback period in their situation is 16 years?

Replace you boiler when it *needs* replacing. Otherwise you're just
contributing to pollution in the manufacture, transport and fitting of
an unneccessary replacement.
