Are you tired of freezing while enjoying the great outdoors on your patio? A patio heater can do the trick, but most of us have no idea how much propane these devices use. The amount of propane used by a patio heater varies depending on a number of factors, including the BTU rating of the heater, the temperature outside, and the size of your patio. However, you don’t have to keep guessing – we have some answers for you.
First off, it’s important to understand that BTU, or British Thermal Unit, is the unit of measurement used to determine just how much heat a patio heater is capable of producing. On average, most patio heaters have a BTU rating between 40,000 to 50,000. However, some larger models can go up to 70,000 BTUs. This means the amount of propane a patio heater uses is directly proportional to its BTU rating. So, if you’re using a heater with a higher BTU rating, you can expect to use more propane.
Now, let’s talk about how much propane patio heaters use in terms of a standard 20-pound propane tank. Most patio heaters consume between 1.5 and 2.5 pounds of propane per hour of use. This means that, on average, a 20-pound propane tank can last anywhere from 8-14 hours, depending on the rated heat output of your patio heater. That’s quite a bit of heat to keep you warm and toasty during those cold winter nights.
Patio Heater BTUs and Propane Usage
If you own a patio heater or are considering purchasing one, it’s important to understand how much propane it uses. The amount of propane a patio heater uses is determined by its BTUs (British Thermal Units). BTUs measure the amount of heat a patio heater produces per hour. How many BTUs you need for your patio heater will depend on how large of an area you want to heat and the temperature outside.
- For a small area, such as a two-person table, a patio heater with 5,000 to 8,000 BTUs is sufficient.
- A medium-sized area, such as a four-person table, requires a patio heater with 9,000 to 12,000 BTUs.
- A large area, such as a seating area, requires a patio heater with 13,000 to 20,000 BTUs.
It’s important to note that larger BTUs don’t necessarily mean a more efficient heater. If your patio heater has a higher BTU rating than necessary, it will use more propane and cost you more money. Therefore, it’s important to choose a patio heater with the appropriate BTU rating for your needs.
To determine how much propane your patio heater will use per hour, you can use this simple equation: BTUs ÷ 91,547 = gallons/hour. For example, a patio heater with 40,000 BTUs will use approximately 0.44 gallons of propane per hour (40,000 ÷ 91,547 = 0.44).
| Patio Heater BTUs | Propane Usage (Gallons per Hour) |
|---|---|
| 5,000 | 0.05 |
| 8,000 | 0.09 |
| 12,000 | 0.13 |
| 15,000 | 0.16 |
| 20,000 | 0.22 |
| 40,000 | 0.44 |
Keep in mind that propane usage will vary depending on factors such as the outdoor temperature, wind conditions, and the quality of the propane being used. It’s always a good idea to have extra propane on hand so you don’t run out in the middle of entertaining guests.
By understanding how patio heater BTUs and propane usage relate to each other, you can select the right patio heater for your outdoor living space and ensure you have enough propane to keep it running smoothly.
Factors Affecting Propane Consumption in Patio Heaters
A patio heater can efficiently warm up its surroundings if it has a steady supply of propane. Depending on how often you use the heater and the weather conditions in your area, you may need to refill your propane tank more frequently than you think. Understanding the factors that affect propane consumption in patio heaters can help you optimize the heater’s performance while minimizing the cost of fuel.
- BTU Output: The higher the BTU (British Thermal Units) output of your patio heater, the more propane it consumes. A typical patio heater has a BTU output of 40,000-50,000 BTUs per hour. This means that if you run your heater for an hour at full capacity, it will consume one gallon of propane. However, if you lower the BTU output, you can conserve propane and extend the run time of your heater.
- Wind: Wind is one of the primary factors that affect propane consumption in a patio heater. When there is a gust of wind, the heat generated by the heater can dissipate quickly, causing the heater to consume more propane in an attempt to maintain the desired temperature. This is why it’s essential to place the patio heater in a sheltered area where wind is not a severe problem.
- Outdoor Temperature: The outdoor temperature also affects propane consumption in a patio heater. The colder it is outside, the more propane the heater needs to consume to generate heat. In extremely low temperatures, your patio heater may consume propane at a faster rate than usual, so it’s essential to monitor the tank and refill it promptly as needed.
In addition to these factors, the age and condition of your patio heater, the size of its propane tank, and the frequency of use can also impact propane consumption. To ensure that your patio heater uses propane efficiently, it’s crucial to inspect it regularly for any faults or damages, keep it clean and well-maintained, and only use it when you need to.
| Patio Heater BTU Output | Propane Consumption (per hour) |
|---|---|
| 40,000 BTU | 1 gallon |
| 50,000 BTU | 1.25 gallons |
| 60,000 BTU | 1.5 gallons |
Knowing the factors that affect propane consumption in a patio heater can help you optimize your fuel usage and keep your outdoor space warm and comfortable for longer periods. By monitoring your patio heater’s performance and refilling the propane tank promptly, you can ensure a steady supply of heat while keeping your fuel costs under control.
Understanding Propane Tank Size and Patio Heater Use
When it comes to using a patio heater with propane, it’s important to understand the size of your propane tank and how it relates to the amount of fuel your patio heater will consume. Most patio heaters are hooked up to standard 20-pound propane tanks, but there are also models that can accommodate larger tanks. Here’s what you need to know:
Propane Tank Sizes
- The most common propane tank size used for patio heaters is the 20-pound tank. These tanks are easy to find and easy to transport, making them a popular choice for residential use.
- If you plan on using your patio heater frequently or for extended periods of time, you may want to consider a larger propane tank. 30-pound and 40-pound tanks are available and can provide more extended use. Keep in mind that larger tanks are heavier and can be more difficult to transport.
- If you have a commercial-grade patio heater, you may need to use a larger propane tank, such as a 100-pound tank. These tanks are not readily available at retail stores and will need to be obtained through a propane supplier.
Patio Heater Use
The amount of propane your patio heater will consume depends on several factors, including the BTU (British Thermal Unit) rating of your heater, the outdoor temperature, and the wind conditions. Higher BTU-rated heaters will use more propane, while colder temperatures and windy conditions will also increase propane consumption.
To calculate how much propane your patio heater will use, you’ll need to know the BTU rating of your heater and the number of hours you plan to use it. Here’s an example:
| BTU Rating | Hours Used | Propane Used |
|---|---|---|
| 40,000 | 4 | 5.33 pounds |
| 40,000 | 8 | 10.67 pounds |
| 40,000 | 12 | 16 pounds |
As you can see, a patio heater with a 40,000 BTU rating will use about 1.33 pounds of propane per hour. Keep in mind that this is just an estimate and actual usage may vary depending on the factors mentioned above.
Calculating the Cost of Propane for Your Patio Heater
Having a propane patio heater can be a great way to extend the use of your outdoor space, but it’s important to factor in the cost of propane when considering its use. Here’s what you need to know about calculating the cost of propane for your patio heater.

How Much Propane Does a Patio Heater Use?
One of the most frequently asked questions about propane patio heaters is how much propane do they use. The amount of propane a patio heater uses depends on the heater’s BTU rating and the length of time it’s in use.
BTU (British Thermal Unit) is a measurement of the amount of heat energy required to raise one pound of water by one degree Fahrenheit. The higher the BTU rating of a patio heater, the more fuel it needs to burn, and the more propane it consumes. On average, a patio heater with a BTU rating of 40,000 can consume one gallon of propane every two to three hours.
| BTU Rating | Propane Consumption (per hour) |
|---|---|
| 30,000 | 0.75 pounds |
| 40,000 | 1 pound |
| 50,000 | 1.25 pounds |
It’s worth noting that other factors can affect the amount of propane a patio heater consumes, such as wind conditions and temperature. For example, using a heater on a windy day can cause it to consume more propane due to the increased heat loss caused by the wind. However, by and large, the BTU rating is the primary determinant of how much propane a patio heater uses.
