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.
Kind of depends on what you want to heat doesn't it...

Approximately 1/3 gallon on high setting.
4.37 gallons per hour at peak.
2 gals +/-
7500 kgs per hour

A 20 pound propane tank holds 4.1 gallons of LP which equates to about 0.016 cubic meters. If your heater burns 3 m3 per hour the tank will last about 19 seconds. If you meant .0003 then it will last 51.73 hours.
2.2 gallons per hour at full load using Winco-Honda 12kw standby generator model PSS12H.
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.
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.
$17.31 per hour.
