To calculate how many Btu's required to heat a space, multiply the length x the width x the height. A space heater with an output of 45,000 btu/hr would heat a space of 11250ft cubed (lxwxh) If your area is for example 31,250ft cubed allow .25 btu for every foot 31250 divide by 0.25 = 125,000 btu required. This is provided as a rough guide only, you have to take into account the heater efficiency, the insulation of the building, and the amount of heat you want to rise by.
