I have a Morso Squirrel woodburning stove which is small but extremely powerful - it gives out a tremendous amount of heat. It's ok to use in a smokeless zone area so long as you use smokeless fuel. I believe you can now buy woodburning stoves which are adapted to burn wood in smokeless fuel zones but am not absolutely certain about this. I've had my stove for about 15 years and am just replacing a few bits which have worn out.
