Interesting thread. I've been toying with the idea of a pellet stove but they are really expensive. I've got a woodburner and a multifuel stove at the moment. I like John J's idea of installing a small fan - might try that.
This year we've been buring the wood from two old railway wagons we had in the garden and have had demolished - wood for an entire winter plus 5 tons of scrap iron at £175 a ton, nice little earner.
Seasoned hardwood is getting harder to find round us, and more expensive. My supplier says that it's because the nearby Drax power station (the largest coal fired one in Europe) now gets subsidies for burning wood and does so at the rate of 25 tons an hour - a tiny fraction of the coal it burns. If I had the money, I'd buy my own piece of woodland and run a coppice scheme - ah, one day, maybe.
