To calculate the cost per hour for a 400W heater, you need to know the electricity rate per kilowatt-hour (kWh) charged by your utility company. For example, if the rate is $0.12 per kWh, a 400W heater would use 0.4 kWh per hour (since 400W = 0.4 kW). Multiplying 0.4 kWh by $0.12 gives you a cost of $0.048 per hour to run the 400W heater.
To convert from kilowatts (kW) to British Thermal Units (BTU) per hour, multiply by 3412. Therefore, a 5kW heater would produce 5 * 3412 = 17060 BTU per hour.
A 18,000 BTU heater uses approximately 0.157 therms per hour. This can vary slightly depending on the efficiency of the heater and the specific model.
15,000/305=49.1 hours.
A water heater pilot light typically uses about 3-5 cubic feet of gas per day.
propane has 21,548 BTU per pound so about 2 1/2 pounds per hour remember that propane is stored in a liquid and you need a big enough tank to allow the propane to change from a liquid to gas.
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.)
A pilot light in a typical gas appliance consumes about 600 to 900 BTUs (British Thermal Units) per hour.
To calculate the cost of running a 2 kilowatt convector heater per hour, you need to know the electricity rate charged by your utility company. Let's assume the rate is $0.12 per kilowatt-hour. In this case, running a 2 kilowatt convector heater for an hour would cost $0.24 ($0.12 x 2).
Liters of oxygen gas per hour x 0.0353 = cubic feet per hour
