What is a Low Pressure Propane Burner

What is a Low Pressure Propane Burner? (What’s the Difference with High Pressure)

You may not know this, but your propane burner comes in two types: a high-pressure propane burner and a low-pressure propane burner. 

Many probably may not realize this until you are told, and if you have noticed the change between your burners, relax something is not wrong. It’s just a different type.

With this in mind, you begin to ask what is a low pressure propane burner? What is a high pressure propane burner? Is there even a difference between these two? 

But of course, there is a difference; we will elaborate on that topic and when and when not to use a high and low pressure propane burner.

What Is a Low Pressure Propane Burner?

A low pressure propane burner controls gas intake to about 6 ounces per square inch, while high pressure propane burners control gas intake to about 60 pounds per square inch. Knowing this is important, so you don’t use a burner made for outdoor use.

Outdoor burners like camp stoves do not control the gas intake, and the emission of carbon monoxide like a low pressure burner does. The emission of carbon monoxide in an enclosed space can be hazardous to your health.

With this understanding, you know that high pressure burners are suitable for outdoor use only. When using low pressure burners, you have limited control when it comes to regulating the pressure. 

When To Use a Low-Pressure Burner

Low-pressure burners are perfect to be used in an enclosed space since you can control the amount of carbon monoxide emitted from this burner. Low-pressure burners should be kept near the gas tank for residential use.

Low-pressure burners are also useful in areas with no natural gas pipelines network or natural gas lines. 

Though a low-pressure propane gas regulator needs to be attached to your tank, we’ll discuss that later. Natural gas that flows through pipelines delivers slowly compared to propane butter.

Low-pressure gasses are mostly used in hotels, restaurants, and island resorts located in hilly areas as it offers a soft jet that doesn’t make food burn quickly. Another upside is that low-pressure burners can be used to fuel smokehouses, grills, and girdles.

If you are wondering what a smokehouse is, a smokehouse shields your burner from the wind. This way, you will need less fuel since your cooking is not being interrupted by the wind.

What Is High Pressure Propane Burner

As we have previously discussed high pressure, propane burners regulate gas intake to 60 pounds per square inch. 

A high pressure burner emits carbon monoxide and should not be used indoors or in an enclosed space, as it can pose a drastic hazard to your health. A high pressure propane burner allows you to control or regulate the amount of pressure.

When To Use a High-Pressure Propane Burner

A high pressure propane burner is best for cooking in a windy and very cold environment. It provides more propane for the burner to work with.

The high pressure regulator provides the burner with enough propane, thereby making the flames hotter and stronger. 

A high pressure propane burner is best used outdoor for this reason. It can be used in campsites or for backyard grill time.

Though using a high pressure propane burner means using a lot of propane in a short period. Suffice it to say, the only time a high pressure propane burner can be used is for an outdoor cooking activity.

Why Do I Have Low Propane Pressure?

Over the years, propane tanks have been built with regulators. If your tank regulator notices a leak in your system, it reduces the flow out of the tank. This usually happens when your burner is turned on when you open the propane tank.

To fix this problem, do not leave your burner on while your propane tank is open. Make sure that your propane tank is closed and your burners are turned off. 

You can now proceed to open your tank and then light your burner when you want; light the other burners to ensure that the flow of propane is equal and on a normal scale.

In some cases, your burners may have been clogged with first and will reduce the pressure on your burner, but this doesn’t affect all your burners at once and is only applicable to one burner.

Is A Propane Stove High or Low Pressure?

A propane stove can be both high and low pressure. Years back, most propane stoves were built for outdoor use like grilling, but propane stoves have been introduced that can be used indoors. 

An indoor propane stove is connected to a propane tank that sits outside. An outdoor propane burner can also use a tank that sits close to it.

 Propane enters the stove with more pressure than natural gas because a piece called the orifice is adjusted or removed.

What Is the Difference Between A High-Pressure Propane Burner And A Low-Pressure Propane Burner?

The major difference between a high-pressure propane burner and a low-pressure propane burner is that low-pressure burners control gas intake to 6 ounces per square inch. In contrast, high-pressure burners, on the other hand, control gas intake between 1 and 60 pounds per square inch.

High-pressure propane burners are best suited for outdoor use since they emit a considerable amount of carbon monoxide, dangerous to human health. On the other hand, low-pressure propane burners do not release carbon monoxide and can be used indoors and in an enclosed space.

High pressures are mostly used in campsites and outdoor grilling activity, while low-pressure burners are mostly used indoors for cooking activity. 

High-pressure burners are suitable for outdoor activities because more propane reaches the burner, giving out hot and strong flames. 

If you are in a windy area, cold area, or an area with high humidity, high-pressure burners are good for you because even the wind doesn’t stop them from cooking your food.

While low-pressure burners are best for indoor uses and are used by restaurants, resorts, and even smokehouses. 

The low-pressure burner offers little control over the pressure, unlike the high-pressure propane burners that fully control the gas pressure.

Less fuel is wasted when using the low-pressure burner. This is because it is used indoors or in a smokehouse protected from the wind and cold temperatures, so it conserves fuel. However, the high-pressure propane burner consumes a lot of gas within a short period as it must deal with the wind and cold temperatures.

The low-pressure burner is a safer option than the high-pressure propane burner.

What Is the Psi of a Low Pressure Propane Burner?

What is PSI? It means pressure per square inch. Propane gas requires pressure to ensure that it is kept in a liquid state. 

According to gas laws, the pressure in a propane gas changes with a temperature change. For instance, if a normal 20-pound propane tank sits outside on a 70-degree day, it will have a psi of about 145, but if it sits outside on a 100-degree day, it will have a psi of about 172.

 The psi of a low-pressure propane burner is below 100, a normal psi ranges from 100 to 200, while an extremely high psi exceeds 200.

To properly check the pressure on your gas, you can consider using a pressure gauge. A pressure gauge is fixed between the regulator and the shut-off valve of your propane tank. 

Release the tank and allow the gas to pass through the gauge; the gas should pass through the lowest psi reading of 10. Close the shut-off valve and allow the gas to stand in the gauge for about 3 minutes.

If there is no increase does not decrease, then you have a stable flow. But if there is an increase, it indicates that your tank has a faulty valve, and a decrease tells you that there is a leak. It would be best to keep your propane tank in an environment with a suitable temperature to maintain constant pressure.


We have discussed a low-pressure propane burner and a high-pressure propane burner. We have listed out what makes them different and the best environment for them to work. 

With this knowledge, you should know that a high-pressure propane burner should always be used outside, as the carbon monoxide it emits is toxic.

We have also talked about why your burner may have a lower pressure than usual; the solution to this problem is straightforward. 

We have given the appropriate pressure for a low-pressure and a high-pressure propane burner and determine the pressure using a pressure gauge. These are all basic guides for using a low- or high-pressure burner.
