Yes, usually. 100 watts equates to about 341.21 BTU per hour.
A 2.5 ton A/c is the same as 30,000 BTU's 1 ton = 12,000 BTU's
1 ton = rate of heat absorption to melt 1 ton of ice in 24 hours =12,000 BTU per hour = 3,516 watts.
Heating units are not measured in tons as AC units are. Heating capacity is referred to in 1000`s of btu output per hour of operation. The ratio of input vs output = the efficiency rating, for example if your home furnace is rated at 100,000 btu per hour input and 80,000 btu per hour output . it is 80% efficient (when it was new). For AC 12.000 btu = 1 ton.
60 000 thousand btus
Propane = 91,600 btu per gallon
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.
If there are 93,000 btu's per gallon of propane, and you are burning 25,000 per hour. That would be 3.72 hours per gallon or approx .27 gallons per hour. 6.45 gallons per day.
BTU per hour is a measure of power. Cubic meters is a measure of volume. Perhaps you mean cubic meters of propane, alcohol or some other fuel.
Propane has a heat content of 19,900 btu/lb net. This means that a 36000 btu/hr heater needs to burn 1.809 lbs of propane per hour to produce this amount of heat. A 40 lb bottle will last about 22 hours if the heater runs continuously.
which is heavier Propane and Butane are _______ than air:
One pound of propane will produce 21,622 BTU's. 20 pounds of propane will produce 432,440 BTU's. A heater that produces 80,000 BTU's per hour will produce heat for almost 5 1/2 hours.
A 10,000 BTU heater will use about 1/2 pound of propane per hour. Conversions to different types of energy being used (ie steam, KwH, etc.) will vary the answer, as will variations such as leaks, 02, temperature setting, efficiency, etc.
7.5 kW equates to 25,591 BTU/hour.
1 cal/day*0.003968321 Btu/cal *1day/24hr = 0.003968321/24 = 0.000165347 Btu/hr
1 kW is equal to about 3,412.14 BTU/hour.
There is approx 100,000 BTU per gallon of propane. A 100 lb propane tank holds approx 23 useable gallons. So that is 2,300,000 BTU. If the heater ran constantly burning 25,000 per hour that would be 92 hours straight.
