1 gallon of propane is about 90,000 BTU/hour. A 20 lb tank holds a little more than 4 gallons. My patio propane fireplace is 60,000 BTU. At full blast, a 20 lb tank will last about 6-7 hours, which is really close to the calculation. 32 people found this useful.

Pool heat pumps can last 10 years without a single problem, and many pool heat pumps remain in service for 20 years with only minor service.
