oowee Posted November 21, 2016 Report Share Posted November 21, 2016 Whatever size stove you go for get a stove that allows for a direct air supply feed for it. You will massively increase the useable heat. When a log burner runs the gas coming out the flue is enormous. Much of that gas will be drawn as air from the room and that will be replaced by cold air from out side. The bigger and hotter the fire the more cold air will be drawn in. A direct air supply will negate this. Its a no brainer. More heat less wood. Quote Link to comment Share on other sites More sharing options...

AVB Posted November 21, 2016 Report Share Posted November 21, 2016 We are having some building work done and were thinking of adding a log burner to the kitchen/family room. Thought that there was a simple route for the flue but was told that no more than 20% of the flue length can not be vertical and that as the flue would be at the front of the house we would need planning permission. Might not be possible now. Quote Link to comment Share on other sites More sharing options...

Simple, to get round H&S you may need to put a guard round it and a sign saying "Caution Hot Surface" Quote Link to comment Share on other sites More sharing options...
arm3000gt Posted November 21, 2016 Report Share Posted November 21, 2016 (edited) I have a 5kw stove in a similar size room to the OP. The flue runs through the house and is boxed in, in the bedroom above in a cupboard. Downstairs is single wall flue and from then on is twin wall flue exiting through the roof. The cupboard has vents at the top to allow the warm air to circulate into the upstairs, it also warms the cupboard. Usually on relatively mild days if on for 6 hours or more it warms the house sufficiently so the heating only comes on for a brief period. On cold days, sub zero outside we keep the downstairs door closed and it happily heats the whole downstairs to 24 + degrees.
