Wood burning stoves are an extremely efficient way of producing heat, they can typically run at around 80% efficiency but that is no reason not to make them even more efficient by using a stove fan.
This ingenious little device sits on top of the stove, it works best if it is sited towards the back and more or less out of sight. The heat from the stove drives the fan which then circulates warm air into the room rather than letting it build up above the stove.
Ecofans are particularly recommended for wood burners fitted into inglenooks or other recesses where they help to push the heat out into the room. An Ecofan costs nothing to run and will pay for itself very quickly in extra comfort and reduced fuel bills.
