Depends on the BTUs of the heater.
There are about 1030 BTUs in a cubic foot of natural gas. If one wishes to know the gas consumption (in feet3 per hour) for a given BTU per hour usage rate, one would divide the amount of BTUs by 1030. That would yield the number of cubic feet of gas that is used per hour. Q: I'm heating a space using 10,300 BTUs per hour and I'm using my natural gas heater to do it. How many cubic feet of gas am I using per hour? A: 10,300 BTUs (the heat generated per hour) divided by 1030 (the number of BTUs per cubic foot of gas) equals 10 cubic feet. You're using 10 cubic feet per hour. You apply 10,300 BTUs to heat the space per hour, and you use 10 cubic feet of gas per hour to do that. (And yes, I picked easy numbers.)
Liters of oxygen gas per hour x 0.0353 = cubic feet per hour
Number of BTUs not relevant to this. A 1350 watt heater is 1.35 kilowatts. When operating one hour, will consume 1.35 KWhours. 1.35 x .07= your answer per hour.
The easiest way to compare gas and electicity costs is to determine what your local electric company charges per kilowat hour and how much your local gas company charges per gallon. Average how long a gallon would last you per hour and compare that cost to the kilowat per hour charge.
