I plan to have my old back boiler replaced with a modern combi boiler. My
plumber has said that there are new regulations coming out (April next
year?) that say that all new boilers fitted must be of the condensing type.
He says that although these are supposed to be more efficient he prefers the
existing type that he currently uses and has advised me to get one while I
still can. I think the model was a Worcester Bosch 28i. I'm concerned that
if these current ones are soon to be banned that maybe there's a good
reason. What are the pros and cons? Is there any difference in the price of
the boiler or installation?

Thanks
