OHelen, thanks to you and everyone else that has responded to my questions, I hope that armed with your comments,i will be able to sort this for the winter, and maybe get some brownie points from 'she that must be obeyed'  thanks again....

Kevin, thanks, but excuse me for being thick, how does this work ? and where can i get one ? where does the hot air come from if not from the chimney which would be full of woodsmoke ?  any help would be much appreciated as last winter all the upstairs was freezing cold.

sounds a good idea to pipe the heat through the house ,but, is it safe to put fumes from a chimney into bedrooms ??  doesn't some wood produce hazardous fumes, or even worse carbon monoxide ? also, does anyone know about register plates to shut off the chimney, and should you have a flue that goes right up to the roof ??
