How Much Propane Does A Patio Heater Use?

Today I’ll be discussing the quick topic of how much propane is used in an outdoor heater. And as a bonus, I will give you some great tips.

Most outdoor propane heaters are capable of holding up to 20 pounds. They come with a 20-pound tank and fill up to 80% capacity, so you can only fill them up to 16 pounds.

It totally depends on the usage of the heater and the area you want to heat on the consumption of propane by a patio heater. Usually, propane patio heaters consume approximately 50 pounds of propane for one month if the heating area is around 600 to 650 sq. feet.

Propane gas is an excellent source of heat energy. There are many kinds of propane gas heaters and each type generates different amounts of heat energy. You can choose a type depending on the space requirements.

How Long Does A Propane Tank Last On A Patio Heater? 

A propane tank is good for about 12 hours of usage on a medium flame setting. On the other side, one pound of propane will last for about 3 to 4 hours with medium flame and 0.5 hours with the high flame setting. Propane patio heaters use approximately 11 lbs (approx) of propane per hour

A patio heater uses approximately 1.5 propane tanks per hour on high flame, or about 5 hours with one tank. A 20 pound LP gas cylinder will last around 8-10 hours on average, depending on the setting of your patio heater. This is based upon a 14,500 BTU patio heater and an outside temp of 65 to 70 degrees.

How Much Does LP Gas Cost?

The cost of propane varies throughout the U.S., but on average, homeowners spend about $3.00 per gallon for propane. Even though this is more than 2 times the price of home heating oil and over 3 times as much as natural gas, propane is still an affordable option for your outdoor space. Propane is measured by the gallon, so you can find out exactly how much propane you’ll need on your patio with this simple equation:

Number of hours to heat the patio x number of BTUs required per hour = gallons needed

For example, let’s say it will take 10 hours to heat your patio area on a night when the temperature is expected to fall below 50 degrees. A patio heater with a 40,000 BTU output would be the right size for the job, and 10 hours at 40,000 BTUs means you’ll need about 1 gallon of propane.
