How Long Does Propane Tank Last in Patio Heater?

Natural gas patio heaters are less expensive than propane patio heaters since there are no upfront fuel costs. Natural gas patio heaters are less costly than propane patio heaters since there are no upfront fuel costs. Propane tanks frequently power patio heaters, but how long do they last? It is a question that many people have considered. Fortunately, the answer to this question is provided below!

Propane prices fluctuate depending on market conditions, sometimes by 15%. The gas can be purchased from a source or a local station that sells it by the pound.

An outdoor propane-fueled heater uses an average of 42,300 BTUs. A 20-pound propane tank has 432,000 BTUs. When the BTUs in the tank is divided by the BTUs in the heater (except electric patio heaters), you get 10.21 hours of heat.

We hope that this information will assist you in making an informed decision on the use of your gas tank.

Three Ways

There are three different ways to read this issue, and we'll address each one separately. Some people want to know how long propane will last, but most homeowners want to know how long their 20-pound tank or 500-gallon tank will survive.

Here's how we can put these questions together:

"How long does propane have a shelf life?" If you have an old tank (whether it's a little 20-pound tank or a sizeable 1000-gallon tank), you'll be interested. That tank has been complete for years, and you're questioning, "Does propane go bad?" Here's a quick answer: Propane has no expiration date. It can be kept in a tank for 100 years and still be edible. Propane has no expiration date, so you can use it regardless of how old it is.

How Long Does Propane Tank Last in Patio Heater

How long do small tanks, ranging from 1 pound to 100 pounds, last on patio heater?

It is determined by the size of your grill, patio heater, and other similar items.

We'll figure out how long a tiny gas tank will survive for various types of propane-powered equipment later on. We'll need to consider the BTU content of propane and the BTU generation of a grill, patio heater, and so on.

How long do large tanks for a house, ranging from 100 to 1,000 gallons, last?

(Depends on the size of the house). It is mainly determined by the heating your home requires in the winter. We'll look at how many BTUs different house sizes (ranging from 500 to 3,000 square feet) need on average and how quickly delivering all that heat will deplete your domestic tank.

Propane never goes stale. It is a byproduct of the natural gas and petroleum refining processes. That indicates it's been in the ground for a million years or more. It doesn't matter if you have a propane-filled tank for a year or 1,000 years; it will still work and contain the same amount of BTUs.

Furthermore, you may be confident that the metal tank's propane tank will survive more than 12 years. It's essentially a corrosion-resistant metal box that will stay for more than a decade (anti-corrosion coating). Now that we've gotten that out of the way let's look at how long propane gas lasts for smaller appliances (grills, propane heaters, portable stoves, even propane generators).

We'll look at how long propane lasts in a large tank. In this case, we'll look at household tanks ranging from 100 to 1,000 gallons for heating. You may estimate how many times you'll need to refill your propane tank each winter based on the size of your home and the size of your tank.

Most common patio heaters emit roughly 40,000 BTUs per hour, which means a 20-pound tank will last about 10 hours on high.

Most full-size patio heaters use a 20-pound tank, which fits into the patio. Keep in mind that a full 20-pound tank weighs about 37 pounds when total and 17 pounds when empty when selecting where to install your propane barbecue or outdoor space heater. The height and diameter of most standard-size propane tanks are 1′ 6′′ and 1′, respectively, with a hose nozzle attached on one side.

The ability of a patio propane heater to accept a full tank of propane varies from model to model, as it does with much other propane equipment.

Before taking their patio heater home and attempting to install it, the buyer must ensure that they purchase a correctly sized propane cylinder.

If someone tries to utilize a 30 pound, there may be issues with performance or safety and probable damage from overfilling or improper installation practices. If the heaters are too small, they may not perform well owing to under powering, and they may even cause injury.

How long does a patio heater's gas tank last?

A 20-pound tank will provide you with approximately 4.7 gallons of fuel and last about 10 hours. You may use that to power up your patio heater for 9 to 15 hours.

How long does a 15-pound tank last?

On a 40,000 BTU patio heater, a 15-pound gas tank lasts typically 8-10 hours.

This time is determined by the outdoor heater and its settings and the number of individuals there at any particular time. The most significant thing to evoke is that you should always have an extra propane tank for your heater on hand if you run out when cooking or entertaining guests!

One of the most popular questions we get from clients is whether or not they may use a 15-pound tank instead of a 20-pound tank on patio heaters. Yes. It depends on the model and brand of the heater, but for the most part, if your regulator can manage both sizes, it should be alright. However, your run time will be reduced if you use a 15-pound tank instead of the suggested 20-pound tank.

At 30 000 BTU, how long will a 20-pound tank last?

The energy content of a pound of propane is 21,591 btu. So, on an actual 20lb bottle, a 21,500 BTU heater would run for about 20 hours. When using a 30,000 BTU heater, multiply 21, 50020 (pounds) =430,000 and divide by the 30,000 BTU heater size. If you run it at 100% all the time, you'll get 14.34 hours.

How long does a 13kg gas bottle last in a patio heater?

When utilized at its maximum setting, a typical 13kW gas patio heater will burn gas at 1230g/h. A 13kg gas cylinder will last for around 10 hours of use – or much longer if the heater is set to a lower temperature.

As previously stated, 20-pound propane tanks are ideal for small chores such as cooking single meals. If you're grilling on a medium-sized barbecue, one propane tank will typically last between 18 and 20 hours. On the other hand, larger barbecues can consume 20 pounds of propane in as little as 10 hours.

What is the average lifespan of a 20-gallon tank?

A 20lb propane tank on a medium grill will give 18-20 hours of cooking time if you follow this rule. In as little as 10 hours, a more giant barbecue can burn through 20 pounds of propane.

A patio heater is an excellent addition to any outside space since it provides additional heat, allowing you to enjoy the wonderful outdoors all year. Don't allow the cold to entice you inside before you're ready; invest in a heating system and make the most of your outdoor area even when the weather turns frigid.

How long does a 9kg gas bottle last for an outdoor heater?

A regular 9kg liquid propane cylinder with a maximum heating output of 30MJ/h will typically last for eight to nine hours on a high setting for a freestanding outdoor gas heater.

How long would a 40-pound gas tank keep you going?

A 40-pound tank can last 21.5 hours before running out of gas.

How long does a 16.4-ounce propane cylinder last?

When used with a 7,500 BTU stove on full flame, a typical 16.4 oz or 1 lb propane cylinder will last two hours.

Small patio heaters generate 10,000 BTUs of heat, whereas large portable patio heaters generate 50,000 BTUs. The 50,000 BTU patio heater will deplete the gas tank far faster than the 10,000 BTU heater (5-times faster, in this case). On a 20-pound propane tank, patio heaters can last anywhere from 7.57 hours to 37.86 hours, depending on the BTU capacity.


There are numerous tank sizes, and the length of time a propane tank will last on a patio heater is determined by the tank size. Small tanks endure for fewer hours compared to large tanks and require more frequent refilling. A regular 20lb tank should last at least 10 hours. The design of the patio heater, the BTUs, and the ambient temperature all determine how long the tank lasts.
