9 Safety Forced Air Propane Heaters Ideal for Heating Up Your Workshop or Garage

Safety Forced Air Propane HeatersLooking to add some quick heat to your workshop or garage? Well, then a forced air propane heater may do the job just right for you! And if that just so happens to be the thing you are looking for, we listed the 9 best forced air propane heaters for you to consider!

Where Is A Forced Air Propane Heater Used?

Forced air propane heaters are typically used in workshop or industrial applications. They aren’t used for home heating since there are way better alternatives to them. Regular propane, gas, or electric heaters are going to be better for home heating since they will likely be more space-efficient, less expensive, and more feature-rich.

Here’s where you could use a forced air heater:

  • In an animal barn
  • Outdoors (to melt ice on your driveway, for example). Not all forced air heaters will be certified for outdoor use though.
Do not use forced air propane heater in poorly ventilated areas.

How Does It Work?

Forced Air vs Radiant Heating

At their basics, forced air propane heaters work just like any other heater. Namely:

  • The burner is ignited by a standing pilot, electric spark, or another type of igniter.
  • Heat is produced through the combustion of fuel (propane in this case).
  • The heating of the room takes place via convection (movement of heat from one place to another).

The key difference of forced air heaters from other heater types is that they have a fan to help move the heat around. This is why these heaters are called forced air – they are forcing the air to move around via the airflow delivered by the fan. The fan doesn’t increase the heat output of the heater, but it does assist with convection and heat spread throughout the area.

How To Choose The Right Forced Air Propane Heater?

You have 9 great models to pick from, but how do you choose the very best forced air propane heater for your needs? Well, below, let’s have a look at the things that matter in forced air propane heaters.

Cordless vs corded

First, consider whether you want a corded or cordless unit. Forced air heaters require power for the fans and the ignition system (if it’s electronic). To get power, corded heaters are plugged into 120V outlets and cordless ones rely on a battery.

The benefits of cordless forced air heaters are simple – they can be easily moved around the job site without having to worry about the power cord length. Besides, they can be operated in areas where there is no electricity.

On the other hand, you will have to worry about the battery that powers electronic components. Namely, you will have to recharge it every once in a while. Not that the electronic components will drain the battery in minutes, but you’ll have to pause your work every few hours.

Some cordless forced air heaters will require you to buy batteries separately. For example, the DeWalt DXH70CFAV is a cordless heater but it doesn’t come with batteries, you need to buy them separately.

Heat output

Then, you have to consider the heat output of the forced air heater. It should not be over-the-top for the area you will be heating – you’ll spend more money on a more powerful heater, and if you don’t use its potential, then you’ve wasted money.

It’s quite difficult to pick the right heat output for given room size. There are plenty of factors involved in how effective a heater will be, including the area’s insulation, the desired temperature increase, and the outdoor temperature.

You may find simple BTU-to-area size charts online, but these don’t really work well for workshop or industrial applications. If you need a more precise way of determining the right amount of BTUs, then you should first consult the manufacturer’s recommendations. Most sellers indicate the max area that a heater can warm up.

You may use online BTU calculators like this one as well. This particular calculator should be pretty accurate since it takes into account the room dimensions, outdoor temperature, and insulation.

Or, you may use manufacturer guides. For example, Mr. Heater provides this BTU chart based on room volume:

BTU Per Hour
Cubic feetThe desired temperature increase in Fahrenheit
20304050
5,00014,00020,00027,99934,000
7,00019,00028,00038,00047,000
10,00027,00040,00054,00067,000
15,00040,00060,00080,000100,000
20,00054,00080,000107,000133,000
30,00080,000120,000160,000200,000
50,000133,000200,000266,000333,333

Keep in mind that most charts will give BTU guides based on the room area, while this chart is given for the room volume. This chart will likely be more precise for your needs, but you may have to do some trial and error to choose a properly-sized heater.

Heat settings

The heat adjustment is also very important in forced air heaters.

It’s one thing to have a heater that can produce 120,000 BTUs, but it’s a whole another thing when you can control the amount of heat coming out of the heater. In certain situations, you would want to have some flexibility in heat adjustment.

This is important because you don’t want to work in a hot room. Besides, you’ll be using less energy by adjusting the heater down to get only as much heat as you need.

Pay careful attention to how the heat output is adjusted in a forced air heater. You may have 2 settings, or you may be able to choose any setting from a given range.

But while adjustability is great, in certain situations, even one heat setting would do a good job. For example, you may get a simpler heater for outdoor use, though it would still be less energy-efficient than an adjustable heater.

Integrated fan/blower

The fan or blower is the key element in a forced air heater. While it’s not easy to choose a heater based on the fan alone, it may be an important thing for you to consider.

The key spec of a fan or blower is its airflow measured in CFM. Unfortunately, it’s difficult to say how CFM is going to affect a heater’s effectiveness in heat dispersion. But the general rule is that the higher the CFM, the more air the heater will be able to move around.

Thermostat

If you want to up the fuel-efficiency of your heating, then you should look for a forced air heater with thermostat.

Unfortunately, none of the overviewed models come with one. Usually, only the largest and most powerful forced air heaters come with thermostats.

The job of a thermostat is to adjust the heat output of the heater as the temperature changes. Alternatively, the thermostat may turn the heater off once the selected temperature is reached. This allows minimizing the use of fuel and electricity when heating is no longer necessary.

A thermostat is a great feature, but as mentioned above, most of the smaller forced air heaters don’t have them. You may try to hook a thermostat to your heater if you’re tech-savvy though.

Tilt protection

Some forced air heaters will have tilt protection. Basically, the unit will shut down if tilted.

This feature makes more sense in small units that are easy to tip over. Heavy and large heaters don’t really need it since you probably won’t accidentally kick them down. But depending on the terrain, you may want to get a heater with tilt shutoff just in case.

High-temp protection

You probably won’t find a forced air heater that doesn’t have overheating protection (also called high-temp protection). This is an essential feature that any forced air heater should have.

With that said, pay attention to it and make sure that the desired heater does have overheating protection.

Flame-out protection

Some forced air heaters also have flame-out protection. This feature shuts the heater down if the flame goes out for some reason. Most forced air heaters out there probably have this feature, but if you do want it, you should make sure just in case that the desired heater indeed has it.

Size and weight

Be also careful with size and weight. Forced air heaters tend to be compact and light enough for transport, but there is a big difference between a 20- and 40-pound heater. If you won’t be able to carry a heavy unit, go for something lighter.

And when it comes to size, be sure that the job site will have enough space for the heater.

Included hose

Finally, consider the hose included with the forced air heater.

Usually, forced air heaters come with hoses equipped with a regulator. What you should pay attention to here is the length of the hose. Besides, keep in mind that the quality of the included hose may be subpar, so you may need to switch to a better one. Some manufacturers advise against using third-party hoses though.

Safety And Maintenance of Forced Air Propane Heaters

Forced air propane heater safety

There are a few safety precautions you should follow while operating a forced air heater. The manual of your heater should contain safety instructions – if so, then be sure to follow them. But we’ll provide some general safety tips below that you should follow:

  • Use the heater in accordance with local codes and laws.
  • Inspect the heater before each use for signs of damage or dirt. Have the heater inspected by a certified specialist at least once per year.
  • Do not convert the heater to work with other fuel types.
  • Ensure adequate ventilation in the room where the heater is installed. Your heater’s manual should provide you with accurate directions on how much airflow should be provided. If you feel headaches, dizziness, nausea, burning eyes & nose, or dry mouth/sore throat, immediately shut the heater down and ventilate the area.
  • Place the propane tanks at least 7 feet away from the heater. The minimum required distance may differ from area to area.
  • Do not direct the heater’s exhaust towards the propane tanks.
  • Do not use an indoor heater if it has not been certified for outdoor use. Indoor-only heaters will get damaged from water or humidity.
  • Place the heater away from combustible materials (generally 3-6 feet away) and the power outlet (6 feet away). Consult the heater’s manual for more accurate guidelines for your heater model.
  • Operate the heater on a level and stable surface.
  • Do not handle or service the heater while it is running or hot after shutdown.
  • Only connect the heater to a properly grounded extension cord or receptacle.
  • Disconnect the propane tank from the heater before storage, especially if storing the heater indoors.

Forced air propane heater maintenance

Maintenance of forced air heaters will mostly come down to cleanup. When it comes to repairs, you shouldn’t attempt to fix your forced air heater on your own. This should only be done by a trained service person.

No matter which heater model you have, the cleaning process mostly comes down to this:

  1. Shut the heater down and disconnect it from the propane tank.
  2. Let the heater cool down for about half an hour to an hour.
  3. Remove dirt and dust out of the heater with a vacuum.
  4. Wipe the outside surfaces of the heater with a cloth (slightly dampened if necessary).

In most cases, you won’t need to disassemble anything to give your heater a good clean. And unless you know what you are doing, you should not do any disassembly to clean the heater. If you clean the heater at least once per month, you shouldn’t need to do a deep cleanup.

FAQs

What’s the difference between forced air propane heaters and forced air central heating?

While the names of these two heating systems are very similar, they are very different and sometimes confusing to people.

Forced air central heating is a heating system popular in North American homes. In such a system, the heat is produced by a heater (powered by fuel or electricity) and then distributed throughout the home via ducts and vents. A forced air central heating system is not portable.

A forced air propane heater is a portable heater that assists heat distribution with an integrated fan. Portable forced air heaters are vastly different from forced air home systems – they aren’t usually used at home (though they may be), not to mention that they have a different design.

Can you plug a duct to the heater to help with the heat spread?

Probably not since the forced air heaters get pretty hot. Unless allowed by the manufacturer, don’t attempt to do any third-party modifications to your heater.

Can you use a forced air propane heater with no electricity?

You can, but the fan won’t run without electricity. The heater will produce heat, but it won’t have the fan to assist with its distribution. In some heaters, the igniter is also going to rely on electricity.

Where does the carbon monoxide come out of in these heaters?

It comes mixed with the hot air. You should thus ensure proper ventilation in the heated area.

Can you buy a forced air propane heater for garage use?

Yes. You can buy a forced air heater pretty much for any indoor area, but you’ll need to ensure adequate ventilation for it.
