I am considering replacing my boiler as it's about 12 years old and Potterton Puma's are not that great.

I have been given a Worcester Bosch 28si which has hardly been used.
I understand you can't fit a non-condenser combi due to regulation change a couple of years ago.
Is it expensive to convert this boiler to a condenser or is that impossible ?

Thanks

Ok thanks.
Wasn't planning on doing it myself - of course I will use a corgi reg fitter.

it is not possible to convert to condensing boiler,nor should you fit one if you are not corgi reg.

hmm, you can't convert it to be a condensing boiler impossible,
but the regulations are about fitting NEW boilers and your not fitting a new boiler its second hand,
so does the condensing boiler building regulations apply I dont think so. As long as its fitted by a registered gas fitter to the original manufacturers instructions who cares ?
