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.

A 50,000 BTU heater typically consumes around 0.5-0.6 gallons of propane per hour. This can vary depending on factors such as the efficiency of the heater and the temperature setting.
