How many radiators can a 10kW stove produce?
Therefore if a stove has a maximum heat output of 10kw as an example - it is capable of producing up to 10 standard sized radiators of heat to the room. Despite this, stoves are not generally intended to be burned at 100% maximum. Infact, 70% of the maximum achievable should be saturation point.

If you have a big room, the temptation is to purchase a large, magisterial stove - likewise with cosier living spaces, a more compact stove might appear the best choice. However, this isn't the best approach. If too small you'll have to constantly be topping up the fuel load on those chillier days, which risks overheating and can eventually damage the stove. Similarly, bigger stoves need to follow their manufacturing guidelines: starving them of their expected fuel load or firebox temperature will distort the overall efficiency.
