Top 6 Garage Space Heaters in 2017

Mr. Heater MH18B Portable Propane Heater

best garage space heaterThis unit does not need electricity in order to work. If your garage doesn’t have an electricity supply, why go through all the process of getting one, when you can just buy a propane heater for a garage.

This space heater works on propane, so you will need to connect it to a 20 lbs propane tank. You will have to buy a connecting kit separately because the box does not contain one.

The propane powered space heater should produce enough heat for a space of up to 250 square feet, and it’s safe to use indoors. This unit can heat up a larger space if your garage is insulated.

Safety features like the tip-off, shut-off, and the low oxygen shut-off, make this model safe enough to use in an enclosed space.

Pros

  • High Portability – Instead of waiting for the unit to run for a long time to warm up the whole garage, you can just move the heater close to you and feel its effects right away.
  • Safe – This space heater uses an open flame, so it represents a fire hazard, no matter where you place it. However, the multiple safety features make the unit safe and lower the risk of starting a fire.

Cons

  • Open Flame – This unit uses an open flame to produce heat, making it a fire hazard. You have to be careful not to place the unit next to flammable objects at all times.
  • Dangerous Power Source – Propane is a highly flammable gas, and using it to power an open flame heater will always represent a big fire hazard.

Fahrenheat FUH54 Garage Heater

garage space heater reviewsThis 240-volt electric heater has the capacity to warm up a well-insulated space of up to 1,500 square feet when it’s working at its highest capacity. If your garage isn’t insulated at all, this heater will warm up a surface of up to 700 square feet, depending on the heat leaks and the temperatures outside.

The industrial space heater is easy to install. All you need to do is plug it into a wall socket and mount it somewhere. Make sure your electrical circuit has a 30 amp breaker because this unit is too powerful for a 20 amp one. You can use the ceiling mounting bracket to mount it either vertically or horizontally, so the airflow will be distributed over a large surface.

If you want the warm air to be pushed directly towards you whenever you move around the garage, you can adjust the louvers to direct the airflow to you with ease.

Pros

  • Durable – This heater’s casing has a water-resistant coating which will protect it from rust and corrosion. The space heater also has a shut-off feature which will prevent overheating protecting the heating elements.
  • Thermostat – This unit has a thermostat, so it will keep the temperature at the same level you set it to.

Cons

  • No Remote – This unit does not come with a remote control. This is a downside because the heater might be difficult to access if you mount it to the ceiling.
  • Thermostat Doesn’t Show Temperature – You can set the thermostat at different values, but you won’t know the temperature of the room until it gets constant and you can measure it. This can lead to a long process of trial and error until you find the value you want.

Dyna-Glo RMC-FA60DGD Propane Forced Air Heater

top garage space heatersThis gas garage heater can heat up spaces of up to 1,350 feet when it’s working on its highest setting. The unit has a CSA certification for being safe to use both outdoor and indoor.

The heater has a durable steel construction base which will help with keeping debris and dust out. The leg connecting the base to the heater is adjustable, so you can raise or lower the heating angle, increasing the comfort as you want it.

This unit uses a continuous electronic ignition system which will keep the flame burning as long as the gas is running. If the flame is extinguished for some reason or the unit overheats, a safety sensor will instantly shut off the heater.

You will need to buy a propane cylinder separately because none is included in the box.

Pros

  • Great Heating Capacity – This small garage heater will warm up a larger space than you would think when looking at it. You will feel the warmth it produces as soon as you start it.
  • Portable – The advantage of having a portable garage heater is that you can move it around and place it close to you, so you will feed the warm air it produces instantly, without waiting for the whole space to warm up.

Cons

  • Thin Metal – This unit’s tube is made out of a thin sheet of metal, so you need to be careful not to damage it when you’re manipulating it.
  • Short Power Cord – The power cord is short, so you might have some difficulties when you decide on a position to place the heater.

Fahrenheat Ceiling-Mount Industrial Electric Heater

best rated garage space heatersThis industrial electric model is a high efficiency garage heater, but only consider this unit if your garage is large, or small but not properly insulated. The 7,500 Watt heating capacity can produce enough heat for an insulated space of up to 1,300 square feet.

One thing you need to take into consideration before deciding on this model is the fact that you need a 40 amp circuit breaker if you want to run it at its highest capacity. The unit will need 31.3 amps when it’s operating at 7,500 Watts.

The epoxy paint finish is water-resistant so the space heater is protected if you mount it to the ceiling where the air can be damp. The unit is protected against rust and corrosion, so you’ll have it running for years.

Pros

  • Thermostat – The built-in thermostat will turn the unit off and on to keep the garage at the same temperature.
  • No Footprint – This space heater was designed to be mounted to your ceiling, so it won’t take up any space. This is great if your garage is crowded.

Cons

  • No Remote – This model is designed to be mounted on the ceiling, but it doesn’t have a remote control. This means that every time you want to turn the unit on or off or set the thermostat, you have to do it manually. This can be difficult and inconvenient for people with high ceilings.
  • Bad Instructions – Following the indications in the instruction manual can be difficult because the instructions are badly written and sometimes incorrect.

Dr. Infrared Heater DR-988 Garage Shop Heater

best heater for garage or workshopThis space heater is capable of producing 5,600 Watts of heat, enough to warm up a surface of up to 1,000 square feet. The heater uses two heating settings and an adjustable thermostat to control the heat output, so you can always control the amount of heat it produces.

This heater’s large fan helps distribute the hot air evenly over a large surface. The fan will move large amounts of air with ease, so you’ll have a constant temperature around the space in a short period of time.

The heater works somewhat differently than other space heaters you can use to heat up a large area. Instead of warming up the air directly in front of it until it gets hot, rises and lets cold air take it place, this heater will warm up a large quantity of air at the same time. It might take longer to feel the warmth, but it is a more efficient way to heat a large space, so your garage will reach a constant temperature faster.

Pros

  • Quiet – This is not a necessity for a good workshop heater, but it’s definitely a big plus.
  • Good Heat Distribution – This heater is able to distribute the warm air over a large surface. The big fan pushes the hot air further into a room than other space heaters.

Cons

  • Very Obvious – This unit’s red color is very noticeable. Everybody’s eyes will be attracted to it. This might not be the best feature if you’re looking for a good shop heater.
  • Rattling Sounds – Some people complain that this model makes rattling sounds when it works. The fan operates silently, but the whole unit might shake and make those sounds. If this is the case, place the unit on an even surface.

Dimplex DGWH4031 Garage/Workshop Heater

most efficient garage space heaterThis unit is capable of producing 4000 Watts of heat, enough heating for a surface of up to 800 square feet if it’s properly insulated.

The heater’s casing is made out of stainless steel and it’s designed to be mounted on the ceiling, or into a wall. The stainless steel casing will protect the heater from corrosion or rust, and the mounting arm will help you with positioning the heater according to the manufacturer’s specifications, 4 feet above the floor.

You can set the automatic temperature control at values between 45 to 77 degrees F, making sure your garage will always be comfortable when you enter it.

The heater’s fan has a delay function which keeps it from running and blowing cold air until the heating element is warm.

Pros

  • Easy Installation – Installing this unit is easy and straightforward, so everybody should be able to do it quickly, without having previous experience. The heater needs a 220-volt outlet and a 20 amp breaker, which are common in most houses.
  • Good Temperature Control -This unity’s automatic temperature control will keep the temperature constant once it’s set.

Cons

  • Noisy – This is usually not a problem for garage heaters, but this unit is loud. You will have to place it at least 10 or 15 feet away from where you usually stand for the noise level to be comfortable.
  • Temperature Dial On The Back – This heater’s temperature dial is placed on the back, so you’ll have to be careful to place it somewhere you can reach it.

Garage Heating Options

There are many different ways to increase the temperature in your garage or workshop. Here are some of the most popular ways to do that

  • Fan Forced Heaters

    This is the most popular way to warm up a large space, like a garage or a workshop, and includes some of the best rated garage space heaters. These units transform electricity into heat, draw cold air in and use a metal fan of variable size to push the warmed air farther into the room. They usually produce a lot of heat and can raise the temperatures in a garage quickly.

    The major disadvantage of using this kind of heater is that it will produce a large amount of heat, but it’s not very efficient at heating up a non-insulated or poorly insulated area. Once the air is heated and rises above the cold air, it can easily exit the room through a leak.

  • Alternative Fuels Heaters

    These heaters don’t use electricity for power, they use a different power source. The most popular alternative fuels are propane, kerosene, natural gas, or diesel. Their main advantage of using them is that you don’t have to connect the garage or workshop to the electricity circuit, and you can use them independently. Most of them deliver a great amount of heat, but they can use a lot of fuel do to that.

    Burning fuels produce a lot of heat, but it also produces by-products. The most common by-product produces after burning fuels is carbon monoxide. This gas is poisonous if it accumulates in an insulated space, so make sure your garage has proper ventilation if you intend to buy a heater using alternative fuels.

    Another drawback of using this kind of heating system is that it operates with an open flame. This makes alternative fuel heaters a major fire hazard, and you have to be careful not to let the unit run unsupervised. You also have to make sure the heater is not positioned in close proximity of flammable materials, but that’s true for all space heaters.

    A major advantage of having an alternative fuel heater in your garage is that you can use it when there are electricity blackouts or in the case of an emergency.

  • Infrared Heaters

    An infrared unit can be the best heater for garage or workshop, especially if the area is large. Instead of heating up the air molecules in front of them, infrared heaters warm up the objects in front of them directly. This means that once the unit starts working, you’ll instantly feel warmer because it will heat you up directly. After the objects in front of them accumulate enough heat, they will radiate this heat to the air surrounding them, so the whole space will eventually have an even temperature.

    A drawback of using infrared heaters is that you have to stay relatively close to them in order to feel the warmth they produce. If you’re not standing within their working range, you won’t be able to feel the direct effect of infrared radiation and it will take a long time until the whole area reaches an even temperature.

Best Garage Space Heater Buying Guide

There are a lot of factors you need to take into consideration before you decide which is the best way to heat a garage. Is your garage insulated, is it well ventilated, is it connected to electricity, do you use it often or not?

All these factors should influence your decision making, but the most important one is the presence of insulation. Here’s a quick guide to what the right choice is in various situations.

  1. For a Well Insulated Garage

    This is the best case scenario. If your garage is well insulated, all you need to do is measure it and buy one of the top garage heaters of your liking. The most important thing you need to do is find the right size of the unit. Garage heater sizing is important because a unit which is too small will not provide enough heat for the whole space while buying a unit too large for that space can make it uncomfortably hot in a short period of time.

    If your garage is well insulated, you might want to avoid buying a heater using an alternative fuel source because they need a ventilation system. Creating a ventilation system will lower your insulation’s efficiency.

  2. Partially Insulated Garage

    If your garage shares a wall with your house, or if there’s an attic on top of it, it’s considered as being partially insulated because the heat losses are lower. Of course, some garages might not have common walls or attics over them, but they might have one or two walls insulated, which is the same thing.

    If this is the case, you can choose between all the heaters available on the market. You can opt for an alternative fueled model, as creating a ventilation system will come easy. In fact, a draft might occur naturally in such spaces, and no additional ventilation will be needed.

    You need to determine the size of your garage and then consider the heat leaks it might have. If you have three exterior walls (including the ceiling) which aren’t insulated, you need to find a space heater which has a heating capacity large enough for a surface double as large as yours.

    A natural gas garage heater or a propane heater might represent a great solution for this type of space because you won’t need to create an additional ventilation system, and both heating systems usually generate enough heat to cover all the losses created by the poor insulation.

  3. Garage Is Not Insulated

    If your garage does not have insulation, you need to determine its size and look for a heater able to handle a surface at least three times larger than your garage. This is how you can be sure that the heater will have a heating capacity large enough to handle all the heat leaks in the space.

    You shouldn’t go for an electrical heater because they will consume a lot of electricity but a large amount of the heat will be lost through the leaks.

    Heaters using alternative fuels are a viable option for this kind of spaces. They usually produce a large amount of heat, enough to make up for the losses, and their by-products will exit through the same leaks.

    An infrared unit might be the most efficient garage heater in this case. You will feel the heater’s warmth and be comfortable without having to warm up all the air in a room. The downside of using this kind of heating system is that you have to stay within its range if you want to feel comfortable, so you need to place it close to where you spend most of your time.

Garage Heater Installation

Installing a garage heater can be different, depending on what type of heater you choose. Here is how to install the most popular types of heaters.

Electric Heaters – Installing an electric garage heater can be easy or slightly complicated, depending on the model. If the model you choose can run on a 220-volt circuit and a 20 amp circuit breaker, it should be an easy installation, as these features are common in most houses.

Unfortunately, the best electric space heater for garage run on 240-Volt circuits and need 30, or 40 amp breakers, so installing them will be more difficult. First of all, 40 amp breakers are not so common on the market, so you might want to buy a 50 amp breaker instead. Second, if you don’t have a 40 or 50 amp breaker installed in the garage, you should probably call for a professional’s help because you will need to change the breaker to install the electric heater. After changing the circuit breaker, follow the installing instructions in the owner’s manual.

Infrared Heaters – Installing infrared heaters is easy. All you need to do is mount them on the wall and plug the into a wall outlet. Some infrared heater models are portable, so you won’t even need to mount them on a wall.

Alternative Fuel Heaters – Installing an alternative fuel heater is not difficult, but because it uses a dangerous power source you should be extra careful. Here is a quick guide on how to do it

  1. Find The Right Place – Think carefully about the location of your heater because it’s better to place the gas tank outside the garage. Mark the location of the tank and make sure that the heater inside won’t be blocked.
  2. Drill – You will need to drill a hole for the hose connecting the gas tank and the heater. You will also need to drill holes for the mounting brackets that come with the heater. Whenever you need to drill, make sure you measure and mark properly before you start.
  3. Mount The Heater – If you determined where the heater will go and drilled the holes for the mounting system, you can mount the heater. Keep in mind that some models have the gas connection on their back, so you might need to push the hose connecting the heater to the tank through the hole first.
  4. Connect The Heater To The Tank – Now that the heater is mounted, connect it to the gas tank using the hose. You might need some adapters, but they are usually delivered with the heater.
  5. Testing – Now that everything’s connected, test the heater. You need to turn on the gas tank and then the heater. If the flame forms, all is well and you can start testing the heater’s different settings.

Garage Space Heaters Safety Tips

Every time you buy a space heater, you need to be sure it will be safe enough to run. Keeping your property and your family safe should be one of your priorities, so here are some tips you can follow to make sure your heater runs safely at all times.

  1. Careful Placement – You need to be careful where you place the space heater. If you use the garage as a workshop, a gym, or just as a plain garage, you have to place the heater away from the high traffic areas. Every space heater has a power cord, and that alone can represent a tripping hazard, nevermind the danger of tipping the heater. On the other hand, placing the space heater in the farthest corner of the room might make it less efficient at heating the whole space. You need to think about where to place the heater in such a way it won’t stand in your way and interact with your usual activities, but to be close enough so you can feel its warmth without waiting hours for it to warm the place up.
  2. Don’t Leave It Running – Turn the heater off every time you leave the garage. No matter how many safety features your space heater has, it still represents a fire hazard. Make sure that every time you leave you turn the unit off and unplug it, even if you’ll only be gone for a short time.
  3. Keep The Heater Clear – Make sure there are at least 3 feet of clear space surrounding the space heater, no matter where you place it. Even if you’re going to use the heater for a short while, place it somewhere away from other objects, especially flammable ones.
  4. Keep The Children And Pets Away From The Heater – Most space heaters become hot to the touch when they’re working. Even if your space heater doesn’t get hot to the touch, a small child or a pet could reach in and touch the heating elements, suffering serious burns, so keep them away from the heater.
  5. Don’t Repair Or Modify The Unit Yourself – If you want to repair or alter the unit, take it to a certified professional. Making unauthorized modifications to the unit can lead to serious accidents, even when the alterations seem small and simple.

Conclusion

Either if you use your garage for protecting your car from the weather outside, as a home gym, as a workshop, or even as a place you can enjoy and relax, you need to make it comfortable for the cold season, as well. Garage heaters provide the necessary heat for you to keep using the space even when the temperatures outside are below freezing.
