First you need to find out how many amps the heater draws.
Then use this formula:
Volts (220) X Amps = Watts
Then take:
Watts x 3.41214 = Btu/hr
how many square feet does a 14,000 btu heater heat
btu = 7500 watts * 3.14 btu / watt = 23,550 btus / hr
my aircondition is 13000 btu on 220 volt ac is how many watts
Burning Stove - 110,000 BTU How many square feet?

If you're in Celsius, 13459.5 Btu's. If you're in Fahrenheit, 12632.5 Btu's.
A 200,000 BTU wood burning stove will heat 1,000 square feet.
