How Long A Propane Tank Will Last On A Patio Heater

Now we have the necessary factors to determine just how long we can expect a propane tank to last on a patio heater. Using the calculated burn rate multiplied by 4.24 will then result in the expected number of services hours for your propane tank. Using that standard 20lb tank, the formula looks like this:


2.3 x 4.24= 9.752 hours

This is the number of hours a standard propane tank will last on a patio heater, hence that 10-hour average. It is also simple, using this formula, to get the life expectancy from any size or type of heater or propane tank. Owners should also take note, however, that there are other factors at play in determining how long a propane tank will last on a patio heater.

Here are those devil-in-the-details considerations that might play a small role or a not-so-small role in how long a propane tank will last on a patio heater.

How Do Patio Heaters Work

A patio heater produces heat by burning fuel, such as natural gas or propane, or by an element that heats up from electricity. The heat is then intensified by the design of the heater and warms the space under and around it. Unlike a space heater that uses a fan to blow hot air, a patio heater acts more like the sun and produces radiant heat. This method works best for outdoor spaces as it keeps the heat in one spot. Anyone standing under or near the heater will feel the warmth. The idea is to take the chill off, not heat up an open space. A full-size freestanding patio heater has a heat radius of anywhere from 5 to 20 feet depending on the model.



How To Stay Safe When Using Propane Heaters

With any heating source, it’s important to be aware of safe operation. Propane heaters are generally identified for indoor or outdoor use, and heaters specifically rated for outdoor use – such as forced air and tank-mounted radiant heaters – present an increased risk of carbon monoxide poisoning if improperly used indoors.

Carbon Monoxide is a colorless, odorless gas that is produced from incomplete combustion. CO affects the body’s ability to move oxygen to the lungs, and CO poisoning often results in flu-like symptoms. Best practice is to use the right heater for the right space, ensure there’s adequate ventilation, and know the symptoms of CO poisoning. Most propane heaters come equipped with oxygen sensors that automatically shut down the heater before oxygen falls to dangerous levels. Some local authorities restrict the use of unvented heaters in living quarters so it is advisable to check with a reputable supplier or local authority having jurisdiction prior to purchasing or installing an unvented heater.

How To Make Your Patio Heater Last For Years

Find A Local Dealer

Like many avid patio users, you might have a portable patio heater. During winter, these come in handy to ward off the cold as you and your guests settle in on the patio for some late evening drinks! To take good care of your patio heater, take these tips into account to make it last for years to come:

For stainless steel patio heaters use a stainless steel cleaner to remove water/rain marks and any other marks. More stubborn marks on brushed stainle ss steel finish can be removed by lightly using a scourer or brush making sure it’s applied in the same direction as the brushed stainless steel effect – on highly polished stainless steel patio heaters never use a scourer. Avoid placing the patio heater directly under a tree and never place on a slope. Good quality stainless steel models will come to no harm left outside, care is needed is when storms or gale force winds are forecast. To protect against storm damage remove the reflector and cover or move to a sheltered spot.

Powder coated models will benefit from light cleaning using a soapy detergent and washing with clean water. Remember to oil the wheel joints annually and check for any wear and loose bolts.

How Long Does A 45 Kg Gas Bottle Last

Top 10 Best Outdoor Patio Heaters in 2020

A 4.5 kg gas bottle does last about 3 to 4 days cooking a meal a day on a 4 burner BBQ grill, assuming a one hour cook time per meal. A 9kg gas bottle will last about 15 hours, when cooking with a small 2 burner compact BBQ used on high. It will last even longer on lower settings or if only one burner is turned on.

Patio gas will last 6 hours with a 35 MJ patio gas heater. This is based on using the HIGH setting and will last longer if turned down.

A small table top heater will last about 18 hours on a 4.5 kg gas bottle. A 4.5 kg BBQ gas bottle will last a little over 3 hours with a large 4 burner BBQ. A 1-burner compact BBQ will last 22 hours on a 4.5 kg gas bottle. These durations all assume the burners are set on maximum.

Do gas patio heaters work?

Patio heaters either burn a fuel such as propane or natural gas, or they heat using electricity. Instead of blowing hot air that will dissipate into the space between you and the heater, like space heaters do, radiant heat travels through the air to keep you toasty and warm.

What Is A Gas Patio Heater

A gas patio heater, it’s exactly what it sounds like, a heater for your patio that uses gas as its fuel. It is an excellent way to allow you to enjoy the cool breeze of winter, all while having a warm environment around you. Although they are mainly designed for outdoor use, some owners also like to use them in covered porches and similar surroundings for that ever-needed flexibility.

Nowadays, you can find patio heaters in the form of floor-standing, hanging, wall-mounted, and even patio heaters you can keep on a tabletop. These heaters eliminate all the limitations you may have for having fun outdoors.

Can A Patio Heater Be Converted To Natural Gas

In a nutshell, sure. You do, however, lose the ease of portability. Assume you have a natural gas pipe running through your yard. In that scenario, you can use a natural gas heater by replacing the regulator and, depending on the manufacturer, the orifice if it is not incorporated into the regulator.

For the average homeowner’s safety, we recommend purchasing a natural gas patio heater to begin with.

Amazon has a fantastic natural-gas-fueled outdoor heater for residential or business use. Learn more about this natural gas outdoor heater by clicking below.

Is A Freestanding Patio Heater Better Than Wall

The type of patio heater that’s best for you depends on your outdoor space and what you plan to use it for. Freestanding and wall/ceiling mount outdoor heaters bring different benefits to the backyard that must be taken into consideration.

With a freestanding patio heater, you can enjoy the freedom of nearly unlimited mobility around your outdoor space, as well as the luxury of storing it during warmer months. These models are typically fueled by propane or natural gas. Wall/ceiling mount units, on the other hand, run on either propane, natural gas, or electricity. As permanent installations, mounted patio heaters can’t be moved around but are especially handy when placed near regular sitting and dining areas. Their biggest benefit, though, is convenience of fuel — electric models are hardwired into your electric grid, while gas units are supplied fuel via utility lines. You’ll never need to worry about refueling them, unless you’re using a bulk propane tank that needs to be occasionally refilled.

Are Gas Patio Heaters Safe

Well-made gas patio heaters are safe because they are made with specific structures and safety features to keep them safe for domestic and commercial purposes.

However, prevention is always better than cure, and they are only dangerous once you start irresponsibly using them. Try to go through the instruction manual to properly carry out the maintenance, storage, and use of the patio heaters.

The most common concern for many homeowners who opt for a gas patio heater is the risk of tipping over and potentially starting a fire. Nowadays, thanks to the advancements, these gas patio heaters are equipped with special safety features that automatically shuts-off the gas when the heater gets triggered by tipping the unit.

However, regardless of how secure the heaters’ manufacturers claim it to be, always make sure you are doing your part of the work and going the extra mile to ensure safety. This includes firmly anchoring the heater in place, especially if you live in high windy areas.

Other than that, here are few features that can give you peace of mind that your gas patio heaters are completely safe to use at home.

How Close Can A Patio Heater Be To The Ceiling

A patio heater should never be any closer to the ceiling than several feet. You’re rarely exposed to an open flame at any point, but that doesn’t mean that there isn’t any heat.

Your patio roof should always be at the height of at least ten feet from the ground. You could try to slightly turn the heater to the side – to the patio’s open side to improve the way heat is dispersed, and it will be warmer.

These heaters are also safe to use near wood, lattice, umbrellas, and other combustible materials, but you need to maintain a distance of six feet in between. A great thing about these heaters is that they’re portable, so you’ll have no issue moving them to accommodate these conditions. The portability of propane heaters makes them a more favorable choice in comparison to natural gas heaters.

It would be best if you never used propane heaters indoors. These heaters were not designed for indoor use, and you could both cause severe damage to your living area and poison anyone in the room.

These heaters give off carbon monoxide, a highly toxic gas for humans, animals, and even plants. However, it isn’t an issue if you’re using your heater on your patio. There’s plenty of fresh air and natural ventilation around, making it easy for the fumes to leave the area. These fumes are given off in small concentrations, so they definitely won’t be harmful, and you can’t smell them either, so it won’t be unpleasant to sit there.

How Much Does Lpg Cost

A heater that produces 40,000 BTUs will consume about $2 per hour. A propane cylinder that has a volume of a 5-gallon or 20-lb. tank is $15 to $20.  This tank is good for 10 hours if the heater is used continuously. This makes the cost average about $2 per hour.

If the heater is used 3 times every week, the tank is good for two to three weeks. The cost and gas consumption will depend on the model and amount of heat that is generated during every use. The consumption of gas will be faster if the heater is always put on high mode and if the heater is used continuously for long hours.

Amazonbasics Best Cheap Propane Outdoor Patio Heater

5 Best Electric Patio Heaters UK (2021 Review)

The AmazonBasics brand is all about affordability, so it’s no surprise that the cheapest propane outdoor patio heater is an Amazon product. The AmazonBasics propane-powered heater is considered a commercial-grade product, only without the commercial price tag. Similar to the #1 product, it’s a powerful 46,000 BTU and requires the standard 20-pound LP cylinder.

The heating range extends 18 feet in all directions, so even large patio spaces can benefit from this unit. It’s a standalone heater, so there’s no mounting involved, and the wheel assembly makes it easy to move around the patio based on heating needs and group gathering size.

The best feature of the AmazonBasics heater is probably the sturdy construction. It’s built for secure placement and enhanced stability with durable steel construction. Outdoor elements are no match against the steel components and sturdy base. The powder-coated bronze finish ties everything together and gives this heater a contemporary look.

How Much Propane Do Patio Heaters Use

Propane heaters employ 20-pound propane tanks. This size is standardized, so you’ll rarely come across other tanks. These heaters will usually use the propane at a rate of 2 dollars an hour, and your propane tank will last about ten hours. Some sources claim that it could last anything from nine to fifteen hours, though, depending on your heat preferences. If you set your heater settings to low, then you’ll be using your fuel more slowly, and it’s going to last a lot longer.

If you think about it, you’ll be spending just $2.00 per hour to keep warm whenever you’re spending time on your patio, making propane-powered heaters one of the most cost-effective methods for heating your patio.

Now, we’ll compare propane tank efficiency with different heaters. It’s important to understand that different heaters use propane differently. These heaters are measured in BTUs – British Thermal Units. BTUs are a form of measurement that measures energy. One BTU is the amount of energy required to increase a pound of water temperature by 1°F. This ratio is used when talking about heating and air conditioning.

Heaters with more BTUs have greater heat output.

So Just How Long Does A Propane Tank Last On A Patio Heater

The average outdoor heater is about 41,000 BTUs. The common 20lb propane tank holds on average 432,000 BTUs. 41,000 goes into 432,000 10.53 times, which means you will get approximately 10.5 hours of heat time on a 20lb propane tank.

There are various propane tank sizes and how long the propane tank lasts depends on the size of the tank, and how many BTUs your heater is.  Also, you lose a little bit of propane when lighting and at the end of the tanks life when there may not be enough pressure left to flow and stay lit.

So, based on that what are some other advantages to having a propane patio, deck or garden heater that are heated with propane?

What If You Use A Lower Heat Setting On The Heater So How Long Does It Last

This appears basic, however manufacturers do not often promote the decreased heat setting BTUs. However, in order to better understand it, we shall convert the heat output into a percentage. If the maximum setting is 100 percent, a lower level would be…say…50 percent. As a result, your BTUs are cut in half, allowing your tank to last twice as long.

We will remark that an adjustment knob that is less than 50% will lose its ability to radiate heat and combat the cold or chilly elements of the outdoors.

Q: Do Outdoor Patio Heaters Really Work

Yes, patio heaters are very high quality and can work extremely well depending on the model purchased and the shape and size of your patio space. Make sure to determine the square footage of your space, so that you know the amount of BTUs that should be included in your patio heater to properly heat your space.

Can You Put A Patio Heater Under A Gazebo

Yes, you can put your patio heater under a gazebo. But try to keep it away from the walls and the ceiling.

You probably think that you want to enjoy your gazebo even during the colder months of the year, and putting a patio heater could do the trick. You’re right. These heaters are usually a safer choice than fire pits or open fireplaces – mostly because the flame is controlled and you don’t have to stoke it. If you’re using a heater that has an open flame, then you shouldn’t use it in a gazebo – these uncontrolled flames can damage your gazebo, and if the space is too tight, they could harm you as well.

You will notice that many bars, cafes, restaurants, and hotels use these heaters in an outdoor dining or bar environment. Since most of those heaters are electric or infrared, this is entirely safe. Some places use propane heaters, and those that do usually set them on the lowest setting to get the most use from the propane.

It’s also important to keep the wind in mind when purchasing a propane heater you want to use in your gazebo. Heaters with unprotected flames are not suitable for this, and you should avoid them. Similar to indoor spaces, gazebos are sort of restricted, so if you have walls that you can take on and off, don’t put them on if you’re using a propane heater. Carbon monoxide will start to collect since it won’t have anywhere to go, and you’re also putting yourself at risk of lighting something on fire.

Storing Propane Tanks Safely

As mentioned earlier, a single propane tank will only be able to deliver the possibility of powering up the patio heater for an average duration of 10 hours.

If you want to get more, you should get an additional propane tank and store them. However, there are some important safety considerations that you should be mindful of at the time of storing all the propane tanks. 

There should be a gap of at least 20 feet in between two propane tanks. Then you will be able to make sure that no two propane tanks come into contact under the intense heat given out by the heater.

Along with that, you can refrain from experiencing an explosion or a fire. 

The propane molecules that can be found within the propane tank would slow down along with a reduction in temperature. You can expect the pressure of the propane tank to drop when it is cold outside.

This can create a negative impact on the performance that is delivered to you out of the propane tank.

That’s where you should invest money in purchasing a pressure regulator.

The pressure regulator can help you with retaining ideal pressure inside your propane tank at all times. Hence, you can use the propane tank with maximum efficiency at any given time.

How Long Does A Propane Tank Last On An Outdoor Heater

What Size Propane Heater Do You Need

Most patio heaters will measure heat in BTUs and will list the heating area of feet around the heater.

When buying propane heaters, you need to consider the size of the tank as well.  Smaller tanks are going to need to be replaced more often, and if you’re buying a heater with greater BTUs, it will probably have a bigger tank.

Tanks sizes on patio heaters typically range from 20 to 40 pounds.

Don’t assume the bigger tank and greater BTUs are going to be the answer. If you have a tiny patio to heat, buying something designed to heat a huge space will work against you. Figure out what means the most to you and then find a balance between space and power when choosing your heater.

You can do that by taking the total number of BTUs and dividing it by 40 if you live in a more temperate climate or 30 in colder climates. This calculation will help you determine how well the heater will cover your square footage.

Since I live in a cold climate, I would, for example, do this.

40,000 BTUs / 30 = 1,333 square feet.

That’s a very big patio.

What Size Patio Heater Should You Get

Before you buy a patio heater, determine how much space you need to heat and where the heater will be located. Patio heaters come in all sizes. If you have a small porch or balcony, you may be limited by what will fit in the available space. If physical space isn’t an issue, you will want to be more concerned with the BTU output of the unit. BTU stands for British Thermal Unit and is a measurement of heat. Because you’re not heating all the air in an enclosed space, BTU output is a little different for patio heaters. There’s no BTU calculator for patio heaters. The following is a good guide for selecting a patio heater based on BTUs:


Freestanding patio heaters typically produce 40,000 BTUs per hour. This will heat a 20-foot diameter space which is good for a medium size crowd. A tabletop heater will produce around 30,000 BTUs depending on its size, and 30,000 BTUs will heat a radius of 5 to 8 feet. Wall-mount heaters can generate 10,000 to 30,000 BTUs depending on their size. The larger the BTU rating, the larger the heat radius.



If heating with propane, a large BTU output will mean having to change the tank more often. A 20-pound tank can support 40,000 BTUs for approximately 12 hours.




Outland Living Series 401 Best Propane Gas Fire Pit Table

I’m from the south, and around here we call these fire pit tables s’mores tables. Because they are obviously the perfect size and height to make s’mores! It’s so relaxing to sit around this table and watch the little flames dance. It really offers all the benefits of a traditional campfire without any of the work.

I love that the propane tank is completely sealed, and the wicker is made of super weather resistant material. For this fire pit table, I highly recommend also purchasing the accessory package. The accessory package comes with a glass windscreen that not only adds a beautiful design but will make sure that the flames don’t blow into your drinks or snacks.

It also includes a weather cover and an additional lid that can be used to cover the fire rocks when not in use so that you have an average coffee style table. These fire pit tables run on a 20 lb. propane tank, operate at 35000 BTU and come with easy, push-button ignition. In addition, the 8 mm black tempered glass tabletop and 15.5 lb arctic ice decorative glass rock set keep this heater looking amazing while offering safety for those near it.

This is one of my favorite winter products and is a real favorite in my home. It’s more than a heater and is a year-round backyard setting so families, guest or neighbors can get together.
