Anns,
Thanks for your reply, I have had a plummer look at it already and the job is possible, we don't currently have a back boiler, just an open fire with most of the heat going up the chimney !!
Plummer is still to come back with quote. Does your stove heat any rads ? or water. Our plummer is reccommending that we just use it to heat water, not rads as well ?!
