Wood is loaded manually through the upper large fuelling door, and ash is removed through a lower access door. Efficiency is around 83%, and heat is available 15 minutes after lighting. When the heater reaches 40°C, a large fan circulates heated air.
A 93 kW model can heat 1500 m3 and costs £4238 plus about £350 for a flue connection. Not only is the fuel free, but money is saved by avoiding the cost of disposing of it as waste.
