Our main purpose is to teach you about heat guns. Understanding heat guns will make you more confident when it's time to make a purchase.

Read this educational guide if you want to know the specific mechanics of what makes up a heat gun, heat gun safety, and other information that we'll explain throughout on this guide.

What Is A Heat Gun?

A heat gun is a device that delivers a stream of hot hair. On average, they emit heat at around 200°F - 1000°F. Higher end models release heat at around 1400°F. It's important to know the temperature settings of your gun before buying it.

Heat guns create a source of heat that's powered by either gas or electricity. It uses a fan to move the heat from the gun onto the desired object. Because of this, heat guns are fast and efficient as transferring heat and are used for almost any DIY project.

Heat Gun Settings Review

One of the main advantages of heat guns is that they are flameless. Other heat generated devices produce flame; which can be dangerous if left unattended. Also, the flames might damage the surface you're working on and could cause a fire.

For 95% of your DIY projects, a heat gun with a temperature of 750° Fahrenheit is perfect for you. In fact, a multitude of heat guns allow you to adjust the temperature to your liking.

When it comes to price, heat guns can range from $40-$2000. We suggest getting heat guns that are priced between $50-$100 if you're just starting. For those who need an industrial gun for more complex projects, expect to pay a few hundred dollars.

What Is It Used For

Heat guns are versatile machines because they can handle a various set of projects. In this section, we'll talk about the multiple tasks a heat gun is compatible with.

Stripping Paint

For most paint removal projects, heat guns allow you to remove the paint quickly. Once the paint blisters from the heat, it's easy to scrape it off by hand. You'll want a heat gun with a temperature setting of at least 500°F or higher for this to properly remove heat.

Heat guns are great at removing old layers of paint. Heat guns allow you to clean your wall without the use of chemicals fully, or paying for professional assistance.

Stripping Paint

We suggest conducting a lead test before using a heat gun in your home. Homes that were built before 1978 have a high concentration of lead. This can make the paint removal process dangerous as the lead chemicals will infect the entire house.

Lead is complicated to remove unless you are thoroughly trained in it. If you do see any lead in your home, chances are you should ask for professional assistance. Doing this ensures that you'll remove the paint safely without getting in contact with any harmful lead chemicals.

Shrinking Materials

Heat guns are the preferred choice when it comes to shrink wrapping. Shrinking materials are made out of plastic beads. First, place the shrink material over the desired object. Once it fully covers the object, you'll want to apply heat onto the material.

As the heat is applied, the shrink wrap will shrink tightly over the object. You'll want to make sure that you have a heat gun whose temperature settings are powerful enough for this procedure. A heat gun with a temperature range between 400°F - 1000°F are ideal for projects that involve shrinking materials.

Dry Out Damp Wood

Wood can become damp for various reasons. This can become dangerous as constant exposure to moisture can lower the wood's quality. Heat guns are great at keeping your wood dry and working properly.

Drying out Wood Review

For damp wood, we suggest getting a variable temperature heat gun. When wood becomes damp, it starts to crack and become exposed to mold. Using a heat gun to dry out your damp wood is a gentle way to revive the wood and protect from any further damage.

Bend And Weld Plastic

There are some situations in which you'll need to weld plastic. Since plastic is a flexible piece of material, you'll need a heat gun to weld it properly. Some high-quality plastics such as polypropylene (PP) and polyethylene (HDPE) can't be glued and need a powerful heat gun to be welded.


Desoldering is defined as the removal of components on a circuit board. Heat guns are useful for this process as it allows you to safely heat up the required part and remove it from the board.

Desoldering with a Heatgun

Remember, desoldering without the proper training can be dangerous. Call for professional if you are finding problems with desoldering. They can ensure that your circuit board or any other material and leave a more professional result than you could do on your own.

Heat Gun Types

There are quite a few heat gun types:

Electronic Heat Air Guns

This type of air gun uses electricity as a primary source. Most electric heat guns come corded, but some cordless options are available.

If you plan on sink wrapping or softening substances, then you'll need a smaller heat gun. For projects that require a large area of paint removal, you'll need a larger heat gun with more horsepower.

Electronic Heat Air Gun Review

There are two things that electronic heat guns use during their operation: a heating element and a fan. Once you turn on the heat gun, the fan begins to rotate. This rotation takes out the hot air passing through the heating system. This results in a jet of hot air directed onto the object.

Gas Heat Gun

Gas heat guns are powered by either propane or butane gases. Gas heat guns are usually seen in construction and welding field. Most industries tend to use gas heat guns instead of electronic heat guns.

This is because gas heat guns speed up project operations and deliver more power. Also, gas heat guns are easier for shrink wrapping in comparison to electronic heat guns.

Gas heat guns are cost efficient. When using an electronic heat gun, you're using a lot of kilowatts in each operation. This can lead to higher electric bills due to the energy used. Gas guns are a cheaper alternative and can save you a lot of money in the long run.

Gas-Powered Heat

However, you'll want to be safe when using a gas heat gun. They are prone to fires if used neglectfully. To prevent this, keep your work space clean from any naked wires. Your gas gun can get caught in between the wires and potentially cause a fire.

Gas powered guns are not just limited to the industry. You can use them at home for recreational use. We suggest practicing proper safety techniques with a gas heat gun before you use it for your DIY projects.

Infrared Guns

Instead of hot air, infrared guns use infrared heat. On average, infrared guns come at low temperatures ranging from 400°F to 600°F. This gun is perfect for beginners who need a heat gun to complete their small projects.

InfraRed Heat Air Gun

Safety is another advantage of infrared heat guns. This is because the heat is low enough to manipulate the desired materials while also protecting the user from unwanted toxins such as lead.

Consider an infrared gun if you want a safer way to remove paint. They are less expensive than industrial guns and still can help you achieve the desired result. Thus, you should look into an infrared gun if you want a safer alternative than traditional heating guns.

Industrial Guns

Based off the name alone, industrial guns are used by professional industries because of their power. Industrial guns are meant to do heavy duty jobs. They are used in packaging, engineering, and building fields.

Industrial Heat Guns Review

The average industrial gun can emit up to 1800°F of heat. Since these are the most powerful types of heat guns, they are the most expensive. We suggest checking out the scope of your project before purchasing an industrial gun.

Heat Gun AiR Hose

Your heat gun has a regulator which is used to reduce high LP tank pressure into a heat gun friendly pressure. Each heat gun is designed to achieve to maximum operation efficiency at the specific pressure.

While some heat guns allow you to adjust the pressure, you don't want to have it at a setting that's too high or low. This can cause for the machine to malfunction or destroy the combustion chamber.

If your regulator is defective, then you need to take it to an authorized repair center. Never attempt to repair an LP gas regulator. You'll end up destroying the machine and potentially cause a fire.

Understanding LP Tanks

LP tanks are pressure containers that are made to follow the rules and regulations of the American Gas Association (AGA) and the American Society of Mechanical Engineers (ASME). Both organizations ensure that each LP tank is inspected before the heat gun is sold.

There are two types of LP tanks:

  • Vapor Withdrawal: Used for heating guns, cooking grills, and heating appliances.
  • Liquid Withdrawal: Made for internal combustion engines and fuel tanks.

LP tanks have an assortment of sizes. The most common tanks come in 20, 40, 80, and 100 pounds.

Make sure to keep your LP tank in good condition. Not doing so will cause rust to build up in the tank. Don't use an LP tank that's damaged or has a faulty shut-off valve. Maintaining your tank ensures that your heat gun will work effectively and last for a long time.
