Airstream_Bill Posted July 19, 2014 Share Posted July 19, 2014 At 120 volts I would imagine that they would all be about the same. You need 240 volt. if possible. If you know how many AMPS it draws, Say 10 amps at 120 volt it is using 1,200 watts 10X120=1,200 watts. If you know how many watts it uses divide 120 volts into the Wattage say 1,200 and the answer would be 10 amps. You will know its electrical usage for its given BTU output. You can do the same thing if you are looking at a 240 volt air conditioner. The 240 volt will be more efficient for the BTU Output in electrical usage.
