Each gallon of LP-Gas produces 91,502 BTU's of heat. One 27 gallon tank
produces two million BTU's. Total consumption depends on the rate of usage
by each appliance and the operating time. The stove and heating systems
typically use the most gas. With sub-freezing temperatures and high winds,
consumption by the furnace can be very high. Check the tank level often in
cold weather.
Determine Fuel Consumption:
To determine approximately how many hours an LP-Gas appliance will
operate on one gallon of LP use the following formula:
• LP-Gas appliances are rated in Input BTU (British Thermal Units).
The rating is usually stamped or printed on a tag affixed to the
appliance. For example: the Input rating of the appliance is
10,000 BTU's.
• One gallon of LP-Gas produces 91,502 BTU's.
• Divide the amount of BTU's of one gallon of LP-Gas (91,502) by
the rating on the appliance in this example 10,000. Net continuous
operation time for one gallon of LP-Gas for this appliance would
be approximately 9.2 hours.
The above formula can be useful when trying to determine the
approximate length of time a tank of LP-Gas will last. Generally,
LP-Gas appliances do not operate continuously. An example
would be the typical cycling of the furnace or water heater.
Determining how long a tank of LP-Gas will last:
• Combine the BTU input totals of all appliances and the
approximate length of time these appliances operate per day.
• Multiply the number of liquid gallons in the LP tank by
91,502.
• Divide the total of BTU's of the LP tank by the total number
of BTU's the appliances consume equals the approximate
number of hours of operation before refueling.
WARNING: LP-Gas is highly volatile and extremely explosive.
Never use matches or open flame to test for leaks. Use only
approved LP-Gas leak testing solution to test for leaks. Unapproved
solutions can damage copper tubing and brass fittings. Never
attempt to adjust LP-Gas regulators without the use of proper
equipment. Improper LP-Gas regulator adjustment will affect the
performance of LP-Gas operated appliances. Incorrect flame or
explosion can occur. Only qualified personnel should perform any
maintenance or repair to the LP-Gas system.
