The output of stoves is measured in kilowatts per hour (kW).

• Measure your room, length, width, and height i.e. A room 7m x 4m x 2.5m = 70 cubic metres of air.
• Now consider how well the room is insulated? (Double Glazing, Cavity Wall insulation, High ceilings etc).
• For poorly insulated rooms divide the cubic metre by 10,
• For normal insulated rooms divide the cubic metre by 15
• For well insulated rooms the cubic metre by 23
• Our room example of 70 cubic metres divided by 15 (normal insulated) 70 divided by 15 = 4.67kW,
• We would recommend a 5kW stove (85% of the stoves we sell are nominal 5kW stoves)
