It could take an estimated 1/2 gallon to 1 gallon idling for a hour.
1 gallon = 4 quarts 1 week = 168 hours → 7 gallon/week = 7 gallon × 4 quarts/gallon ÷ (1 week × 168 hours/week) = 7 × 4 / 168 quarts/hour = 1/6 quarts/hour
(1 US gallon/hour) x (1 hour/3,600 seconds) x (3.78541 liters/US gallon) = 0.0010515liter/second(rounded)
On average, a 45,000 BTU furnace will consume about 0.046 gallons of propane per hour when running. Therefore, 1 gallon of propane should last for around 21.7 hours of continuous operation for a 45,000 BTU furnace.
Propane has an energy content of approximately 91,500 British Thermal Units (BTUs) per gallon. When converted to BTUs per hour, the amount depends on the rate of consumption; for example, a typical propane heater might consume about 1 gallon per hour, producing around 91,500 BTUs per hour. The exact BTU output can vary based on the efficiency of the appliance and its specific design.
