How do Forced Air Propane Heaters Work?

how does a forced air propane heater for garage work?Primarily, forced air propane works by burning propane and ejecting the hot air to warm spaces. However, many technical processes take place. To understand how forced air propane functions, it is necessary to examine its most important parts.

The heaters comprise a heating element, an igniter, and the main burner. There are other additional features such as heat controls, the propane tank, and a horse. All these elements of the heater function in a coordinated manner for the production and supply of heat.

The process of production of heated air begins with the ignition system. This is a simple combination of a highly volatile material with a spring and a hammer-like object. Common heaters contain a modern ignition system referred to as piezoelectric ignition.

This is more efficient than the old ignition system. When you start your heater, the ignition system converts mechanical energy into electrical energy. A small spark is used to ignite the heating element.

The heating element, which is made of porcelain, plays one key function: to direct the flame towards the propane and ensure the efficient burning of the fuel. The propane is then burned rapidly to produce massive amounts of gases.

The gases produced from the combustion of propane would be useless if they are not directed outside. It is at this point that the importance of the fan becomes apparent. All forced air propane heaters have inbuilt fans to push the hot air outside. Thus, this type of fan produces much heat that can be used to heat large areas within very short times, hence considered the most energy-efficient propane heaters.

You can adjust the burning rate of the propane using either a control knob or digital controls. Most forced air propane heaters for garages that are currently available feature a physical knob.

Advantages of Forced Air Propane Heaters

Proper Heat Distribution

If you are working in a large and closed space like a garage, then you may need a heater that distributes the produced heat effectively. Heaters that lack fans may produce enough heat but fail to distribute it across space evenly.

The good news is that a forced air propane heater is one of the most energy-efficient garage heaters since it has a fan that runs steadily and properly distributes the produced heat across the entire space.


It is very easy to carry your forced air propane heater from one place to another because this type of heater has been designed for portability.

Although only a few brands of common heaters have wheels to aid in transportation, all brands do have handles. The handles can be used to conveniently move the heater from one place to another without straining.

Moreover, the weight of forced air propane heaters makes it easy for one to carry them to and from work. The average weight of most brands of heaters is 25 pounds which is not a big convenience if you have to carry your heater to the garage and back.

Instant Heating

Sometimes when working in a large garage or any other job site, you may require an instant source of heat. Although there are many alternative sources, none matches a forced air propane heater in terms of delivering heat within the shortest time possible.

The operating mechanism of these types of heaters makes it possible for them to generate massive levels of heated air within seconds. Thus, using a forced air propane heater delivers instant heat enough to warm your garage.

Things to Consider when Choosing a Propane Heater for Garage

things to consider before choosing a forced air heater


When choosing a propane heater, consider the kind of controls that are included. Some heaters have manual control knobs that you can use to adjust the rate at which the propane gets burned. By changing the BTU level, you can effectively control the amount of heat that the device produces.

Other heaters including ventless propane heaters for garage have digital controls and additional features such as thermostats and timers. You can use all these control functionalities to adapt the operations of the heater to your preferences and the requirements of your working environment.


The performance of propane heaters is measured in terms of British Thermal Unit (BTU). One BTU is equivalent to about 0.3 watts. It takes about 40BTUs to effectively warm a 1 square feet space.

Therefore, to determine the space that a heater can effectively heat, divide the BTU value of the heater by 40. For example, a heater with a BTU value of 60,000 can be used to provide sufficient warmth in a 1,500 square feet garage.

Ease of maintenance

Maintaining your forced air propane heater requires a degree of technical skills. Following the maintenance procedures that are provided by the manufacturers may difficult for some people. Moreover, some technical problems such as leaks and others may cause bigger problems than anticipated.

Luckily, some brands come with designs that simplify the maintenance process. the use of a split barrel design makes it easy for one to access the motor and other internal components and service them quickly. Therefore, when choosing a heater, consider whether its design favors easy maintenance processes.
