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.
FACT: Heating oil systems have a longer life. The average life expectancy of an oil heat appliance is 30 or more years if they are properly maintained. The average life expectancy of a natural gas furnace is only 11-14 years. And, the efficiency ratings of new heating oil systems range from 83% to 95%.nd, converting a heating oil system to natural gas is expensive, with tank removal, chimney, plumbing and duct work potentially costing over $9,000! 2.
