Best kerosene heaters for garage reviews

Forced air kerosene garage heaters

Kerosene garage heaters that rely on the forced air heating method come in various sizes, but they work in the same way. These devices use a cylinder-type body that blows air in, heats it by combusted kerosene, and then forces the heated air out into space. Thus, they warm the air rather than the objects and are more suitable for enclosed spaces like a garage.

Forced air kerosine heaters have a large heating spread and heat the air quickly. Besides, they are easy to install and use. You can regulate the direction of the heat or set the desired heating level. However, they are pretty loud, and it might take you some effort to find kerosine as it is not widely available at gas stations unlike propane.

Also, mind that forced air kerosene heaters require service every 3 or 5 years, depending on usage. Also, they emit gases and fumes, so it is recommended to ventilate the room and avoid placing the unit near flammable objects.

Mr. Heater MH75KTR – best overall

Radiant kerosene garage heaters serve the same mission – to keep you warm in the garage or any other construction, but they work in a different way. Unlike the forced air heater that soaks up the air around the unit and heats it, these heaters use the reflection of infrared heat waves to warm the objects. Radiant heaters direct the infrared heat outward, meaning that they heat the objects directly in front of them.

Because these devices provide steady warmth without blowing air, they eliminate duct losses. They are also a great choice for allergic people as they don’t distribute allergens. You will also enjoy that the radiant heaters are quieter than forced air ones. Thus, you won’t be disturbed by an annoying sound as you work on your project in the garage.

Kerosene garage heaters buying guide

How many BTU do I need for my garage?

To make certain the heater is capable of warming up the desired garage area, you’ve got to know the unit’s heating capacity. This characteristic is measured in British Thermal Units, BTU, and defines how much thermal energy the heater can release per hour.

To give you a better idea of what BTU is optimal for your needs, you’ve got to consider that an average heater should deliver about 25,000 BTU per 1,000 sq. ft. The industrial heaters emit more than 75,000 BTU and cover 2,000 sq. ft. and more.

Mind that if you have a one-car garage, getting a device with a large BTU rating is not a good idea. Higher BTU means more carbon monoxide, which might be dangerous in small unventilated spaces.

Safety features

Even though kerosene heater manufacturers emphasize sticking to safety measures, they have simplified this by equipping the units with some safety features. These features vary from one item to another, but, all in all, they are meant to ensure you use the heater safely.

Most devices come with the overheat protection feature. The heater shuts off automatically if it detects too much heat.

Another useful feature of the kerosene garage heaters is a flame-out sensor that detects flame-out conditions and turns off fuel valves.

If you have kids or pets, you’ll appreciate the anti-tip over switches that prevent accidents as the heater gets knocked down.

But no matter how many safety features your device has, it’s your responsibility to use it wisely.

Additional features

As you are choosing a great radiant kerosene heater, mind the fuel tank capacity. It will determine the operation time. Usually, the heaters provide around 9-13 hours of work on a full tank.

The fuel rate is another characteristic that should be in your sight. If the fuel consumption is too high, you’ll be making frequent visits to a kerosene fuel dealer. And because kerosene is not cheap, you might not be thrilled about those meetings.

Most kerosene heater models for a garage have an in-built thermostat that enables you to regulate the level of heat. Besides, some devices can work from batteries without an outlet, which might be handy if you want to get a portable heater.


Are kerosene heaters safe in a garage?

The answer to this question depends on many factors, including what kind of garage it is, where the kerosene heater is positioned, whether children/visitors are around, and how often you use it. However, if you follow the rules of operation, they are safe.

Do you need ventilation when using a kerosene heater?

Common sense would tell you that you need to have ventilation, so it is important to check the manufacturer’s instructions and understand the maximum capacity of your heater in terms of cubic feet per hour (CFH) and the required size for proper ventilation.

How do I stop my kerosene heater from smelling?

Kerosene heaters should be allowed to run for 10 minutes or so after they are turned off for all the fumes to clear. If you need to leave your kerosene heater overnight in the garage, make sure it is well ventilated.

Why is my kerosene black smoking?

A kerosene heater that smokes is likely caused by the wrong grade of kerosene being used or not cleaning the wick. In addition, the small amount of water in liquid fuel can cause a film on top of the wick, which will block it so it cannot burn properly. As this black smoke puffs out when you turn on your heater, it warns that the wick should be replaced.

How often should you change the wick on a kerosene heater?

The general rule is to change the wick every season, depending on your usage. In addition, if it smells or smokes when you turn it on after refilling it, it must be replaced.

How do you take care of a kerosene heater?

If you use it regularly and follow the manufacturer’s instructions, you should not have any problems. However, always ensure that you replace wicks when they turn black or smell if they are excessively used. It is important to check all the connections regularly to make sure there at no leaks, especially with small children/visitors around your garage.

Can you leave a kerosene heater in the garage all night?

This depends on many factors. If you are using the heater for short periods only, then it should be fine to leave it in the garage overnight if your garage is well ventilated during this time.

How long does a kerosene heater burn?

Typically a kerosene heater will burn for 2.5 to 4 hours on a full fuel tank, depending on the size/capacity.
