Hi, I'm thinking of having a wood burner stove fitted but can anyone help me understand the heat out put. For instance 5kw. I understand that its 5 kW of energy etc but is anyone able to help me with a more real life explanation, such as how big a room it will heat etc?

Cheers

Maybe a better question to ask is what you want the wood burner for ? heat the WHOLE house ? Then it needs a back boiler and extra gubbins, just one or two rooms? As soon as you go over 5kw You need to have a separate air vent fitted in the room ( IIRC ).

Also , you sure you want a Woodburner and not a Multifuel burner which can burn wood AND smokeless fuel?

Also, not all stoves are created equal.. There are many that might state their output as 5kw, 8kw etc, but some are a lot lower in their efficiency compared to others. Do your research, and you won't go wrong.

+1 for multi fuel - makes life a lot easier. Worth doing your research as mentioned above - stoves do vary + the small print is worth checking. I particualrly wanted to get a UK made one when I was installing mine. Several claim to be uk made, very few are.

Its also worth considering one of the fans for the top of the stove -. I was initially very sceptical but it has made a massive difference in my cottage http://www.galleonfires.co.uk/eco-f...black-blade/?gclid=CJ24q7DI370CFRDItAodbzMAnA. Lots of other sellers out there - this is just an example for illustration

There are calculators for the power of radiators needed to heat any size of space - that's transferable to stoves.

However, don't get an 8kW stove and try to run it at 2kW. It won't work well. If you need, say, 4kW to heat a room, get a stove not a lot bigger than that.

This rule doesn't apply to the likes of Agas, since they work more like a heat store than a simple radiant heater.
