Not really worth it in the UK really as your wood prices are sky high. I get some people may have a small stove in their lounge, but that's more for effect then actual heating as you still have to run rads elsewhere.I'd love a log burner but it's about 3 grand to have one fitted. That's 2 years worth of gas and electric.
We have 4 log burners and a wood fired range cooker. I have 6 acres of woodland at the back of the property so I cut my own wood. Cost me 100 euro a year to heat the house over the winter (tractor diesel, fuel and oil for the chainsaws).
