Hello,

Are condensing boilers mandatory? If so, why are non-condensing models
still in the brochures? As you may know from my recent posts, my
boiler died and I am confused. Some plumbers have visited and quoted
for fitting condensing boilers and some have quoted for fitting
non-condensing. I thought all new boilers had to be efficient. What
are the exact regs. and what is the definition of "efficient"?

Running a condensate drain should be trivial but I think I may need a
new flue liner (see other post) of I go condensing, which adds much to
the cost. I think the other plumbers were trying to save my money (or
their time!) by fitting a non-condensing boiler to the existing flue.

Thanks,
Stephen.
