The Heat Storm Phoenix Floor to Wall Infrared Space Heater is an extremely portable 1500 watt unit, and the heating method here is infrared. This heater has pretty limited power, but it’s enough to heat up a small room or office, as well as a compact garage when the temperature outside isn’t likely to dip too low.

What that means in terms of a rating is just 5,200 BTU of heat output – so, be very careful to only select the Heat Storm Phoenix Floor to Wall Infrared Space Heater for an appropriate space and suitable conditions.

The Heat Storm Phoenix Floor to Wall Infrared Space Heater lets you choose from two power modes. The first utilizes the complete 1,500 watt power rating of the unit, while the alternative setting only uses 750 watts – which makes this a great option where a steady, low background heat is required.

What stands out?

  • Compact
  • LED display
  • App-compatible

What cons did we manage to find?

The Mr. Heater MHVFB30NGT employs a blue flame to provide heat, and the manufacturer boasts that the blue flame version of heater does a better job in narrower or more cramped areas because it warms the air, unlike a radiant heater – which tends to warm objects.

The Mr. Heater MHVFB30NGT can throw out a very respectable 30,000 BTUs of heating power, and safety is covered because there is an automatic low oxygen shut-off system fitted. It’s important to note that the Mr. Heater MHVFB30NGT isn’t safe to use at altitudes higher than 4,500 feet, due to combustion issues.

Type: Propane Wall-Mount, additionally sold base legs allow floor mounting

Heating BTUs: 18.000

Coverage area: up to 700 sq ft

Dimensions: 20.9 x 10.1 x 24 inches

Weight: 20 lbs.

Warranty: 1-year limited

More features: Built-in oxygen depletion sensor

The next heater on our chart of the ten best garage heaters out there is the Dyna-Glo IRSS18LPT-2P. This is a liquid propane-fueled heater and works by the principle of infrared heat transfer.

The Dyna-Glo IRSS18LPT-2P boasts a heat rating of up to 18,000 BTUs and promises to warm up areas of up to 700 square feet. There are three heat settings on the Dyna-Glo IRSS18LPT-2P – you guessed it, low, medium, and high.

However, the choice is more extensive in reality because this heater has a very nice control knob, which will let you set the unit at pretty much any level you find comfortable.

The Dyna-Glo IRSS18LPT-2P is another good option for users out there who experience regular power outages because it requires no power supply to operate.

That means you’ll have a source of heat in the garage, no matter how the weather or the electricity grid behaves.

A downside to the Dyna-Glo IRSS18LPT-2P is that there is no fan fitted to the unit, although you do have the option of buying a separately sold fan unit. Going down that route will allow you to heat a bigger area than when you are using the heater without fan assistance. It’s also slightly disappointing that you have to buy a floor leg kit as an extra too.

What are its best features?

  • Good BTU rating
  • Infrared heating

What could be improved?

  • Poor customer service
  • Quality control lacking
  • Feet cost extra
  • Fan costs extra

8 .Cadet Com-Pak CSC151TW

Cadet Com-Pak CSC151TW


Type: Electric

Heating BTUs: 5.120

Coverage area: up to 175 sq. ft.

Dimensions: 9 x 4 x 12 inches

Weight: 7 lbs.

Warranty: 2-year limited

More features: Thermostat; horizontal or vertical mounting options

One of the smallest heaters on our list is the next heater up for discussion, and that heater is the Cadet Com-Pak CSC151TW.

You don’t get a massive BTU rating with the Cadet Com-Pak CSC151TW – it’s limited to just 5,120. However, what you absolutely do get is a relatively cheap, compact and user-friendly garage heater that has a lot of punch for a smaller unit.

In the right garage, the Cadet Com-Pak CSC151TW will definitely do a decent job of rapidly and efficiently heating up your space – without requiring too much in the way of effort or brain activity.

The manufacturer claims that the Cadet Com-Pak CSC151TW will heat an area of up to 200 square feet, and the built-in fan will only serve to facilitate that more rapidly.

The most notable attribute of the Cadet Com-Pak CSC151TW is its mounting method. This heater flush mounts into a cavity wall, and while that limits the spaces it can be installed in (you won’t be able to use this on a brick wall) when you do fit the Cadet Com-Pak CSC151TW,

you will be using up very little garage space indeed. The supplied kit includes everything you will need for installation, including a wall can and a thermostat for hard-wired installation.

What do we love it for?

  • Flush-mounting
  • Good BTUs for size

What were we disappointed with?

  • Reliability issues

9. DeWalt DXH75KT

DeWalt DXH75KT


Type: Kerosene

Coverage area: up to 1.750 sq. ft.

Dimensions: 32.2 x 17 x 14.2 inches

Weight: 72 lbs. when full

Warranty: 1-year limited

More features: Thermostat; ergonomic handle

The next heater on our list is the DeWalt DXH75KT, which is a portable heater that’s designed for use where you need a significant source of direct heat. Be aware that this unit is mobile, but it isn’t mounted on wheels and weighs 72 pounds when the fuel tank is full, so in this case, portable is a relative term.

Coming from DeWalt, this unit has been designed for worksites and for use when carrying out construction in poorer weather, but that doesn’t mean you can’t use it at home in the garage.

However, it’s critical to remember that this kerosene heater employs an open flame and it’s essential you are extremely careful to remember where it is at all times. You’ll also need to be extremely cautious about providing adequate ventilation to ensure safe use.

What you do get with the DeWalt DXH75KT is a huge 75,000 BTUs of heating power. That sort of output and rate of heating enables areas of 1,750 square feet to be adequately warmed up – pretty impressive!

Overall, the DeWalt DXH75KT is going to be a monster in the garage heating stakes, but it won’t be for everyone.

For most domestic users, this thing will be overkill, and the safety concerns in a frequently used home environment probably outweigh the benefits anyway. Great in the right setting, inappropriate in most garages.

What stands out?

  • Great for renovation work and worksites
  • Massive heat output

What cons did we manage to find?

  • Not for everyone – keep kids away

The ‘Glide-System Pivot’ lever allows users to control where they direct the air flow from the unit. The controls on the Lasko 760000 garage heater are pretty good, and there is a timer incorporated too.

The Lasko 760000 is built to save space, and it’s a slimline unit that will be great to use in a more confined space. It’s also far less likely to get knocked into than many garage heaters, which tend to be bigger and bulkier.

Some users will be attracted to the Lasko 760000 because it comes with a multi-function remote control, which makes it very convenient to use when you need to adjust the heat level frequently. For easy of motion, there’s a handy built-in carrying handle.

All in all, the Lasko 760000 is a heater for a specific type of space. It won’t heat massive areas, and it’s not designed for industrial use. In the right garage, the Lasko 760000 will do a decent job, and it doesn’t cost a packet.

What makes it stand out?

  • Compact
  • Directable air flow

Which disadvantages must you keep in mind?

Things to Consider

Buying any type of appliance can be challenging, and there is always a vast range and choice on the market when it comes to the task of finding the right model for your own needs.

It can be difficult to know which way to turn and impossible to decide just where to start. Luckily, we’ve put together this handy buying guide, which is designed to get you up and running when it comes to choosing your own new garage heater.

We’re going to take a look at what some of the features and specifications you are going to come across when you conduct your search, and we will examine what each of those different terms and attributes means, in plain language.

Choosing the best garage heater

As with anything, choosing the best garage heater for your specific needs will just be a case of working out what you want it to do – before you buy it. Your level of success will only ever be as good as the thought you put into the process of choosing your heater.

It’s helpful to understand a little bit about how garage heaters – and heaters in general – operate. When you’re selecting any type of appliance, knowing how and exactly where you will be using it is the key to making a great decision and ending up with a heater that will give you years of service.

If your garage space is large, that will influence your buying decisions – and likewise, if you’re heating a smaller area. Availability or the lack of an electrical supply will be a factor for some, while portability or size and weight might come into the process for many.


Radiant or Infrared garage heaters, such as Heat Storm Phoenix Floor to Wall Infrared Space Heater, work well because they’re simple and provide a very direct, local source of heat – which can work well in a smaller garage.

You’ll find that in a larger space, however, radiant heaters will struggle to push heat out sufficiently to reach corners which are less local to the heat source.

A solution to this problem can be to use more than one radiant heater, and many people find this more controllable and efficient than relying on just one heat source in a bigger space.

Fan-assisted heaters are great for areas that you don’t tend to spend a lot of time in. This is because the integral fan enables the heater to warm up a space very quickly. Fan-assisted heaters work by passing cold air over a heating element and then circulating that air back out after it’s been warmed up.

Kerosene or natural gas heaters, like DeWalt DXH75KT or Mr. Heater MHVFB30NGT, are the most portable option of all of the garage heater types.

Because Kerosene and natural gas heaters don’t require an electrical supply in order to work, you can use them in remote areas, so they’re a great idea if you’re off the grid – or even if you live in an area where you experience many power outages.

Great care should be taken, however, when using kerosene or natural gas heaters in enclosed spaces, and you’ll need enough ventilation to make sure that the fuel can be combusted thoroughly for safe operation. You’ll also need to be aware that with kerosene and gas-powered heaters, it’s dangerous to use or work with combustible materials.

Heating BTUs

BTU Stands for British Thermal Unit. BTU is essentially a measurement unit of energy, and it refers to how quickly a heating appliance is capable of raising temperature. The unit was derived based on increasing the temperature of a pound of water by one degree Fahrenheit.

What that all means in terms of garage heaters is that the higher the BTU rating you see on the specifications of an appliance, the more rapidly it will be capable of raising the temperature in the space where you intend to use it. This comes down to what you need from your garage heater.

If rapid heat increase isn’t a priority for you, then BTU rating will be less important than if you need a heater that can increase the warmth in an area very quickly. So, for example the average BTU count features Mr. Heater MH25LP and it is capable to heat up to 550 sq ft.

Coverage area

Coverage area refers to the size of the space you require your new garage heater to heat. If you are looking to provide adequate heat in a bigger garage or even a workshop, then you will need to limit your search to heaters that can handle the job and boast a more extensive coverage range.

Smaller heaters will not be able to handle the task of heating your area properly if they are not designed and rated to do so, and it’s absolutely essential that you take this into account before you commit to making a purchase.

Dimensions and weight

Dimensions and weight matter. Every user will have a different end goal in mind when they look to purchase a new garage heater, and each new heater will be expected to perform its purpose in a different environment.

When it comes to looking for your own new garage heater, you will need to think carefully about how you want to use it, and where you will need it to be located.

The heaters on our list come in various shapes, sizes, and weights. For example, our top three heaters range between three pounds – for the wall-mounted Mr. Heater MH25LP – and more than twenty-two pounds in the case of the Sengoku HeatMate HMN-110.

Consider the size of the area you want to heat, and make a decision on a garage heater based also on the space you have available to site it.


With any appliance, having a good warranty is very important. Not only does a decent warranty signal that a manufacturer has some confidence in their device to perform a job, it also suggests that the construction quality of the appliance is sound and that the materials used to make it are up to the job of keeping it functioning for an appropriate period.

Even with a reasonable warranty period, however, it’s essential to check the fine print and take into account who will be responsible for costs associated with returning the appliance for repair in the event it breaks down. Especially with bulkier items such as appliances, shipping costs can mount up, so take care to read the warranty terms in full.

Extra features

Buying a heating appliance that you’re likely to be working near, or even operating vehicles or lawnmowers around means keeping safety in mind, and for that reason, many garage heaters incorporate a range of safety features that are worth considering.

You’ll find that some portable garage heaters have a tip-over switch installed, and this protects against accidents by cutting the power to the heating element if the heater gets knocked over unintentionally.

Thermostats in heaters, like in Comfort Zone CZ220, ensure that operation is safe, even when that operation is prolonged – as is the case with many garage heaters. Thermal overload sensors will also cut the power to the heater if it’s in danger of overheating.

In terms of extra features that are not safety-related, you can look out for adjustable louvers if it’s a thing that you often need to direct your heat source toward a particular object or area – for instance, if you are carrying out work that requires drying time.

Carrying handles are almost essential on portable heaters, so if you want to move your garage heater around a lot, look at the carrying features the manufacturer is providing.

If that’s the case, you might also want to check out how cool the body of a heater will be after operation, and some heaters have a cool-touch feature, which makes them very user-friendly.

Staying with portable heaters, if the model you’re considering is large and heavy, make sure you look at the wheels. Wheels make life easy, and it’s why they’ve been around for a while.

Price range

Garage heaters come in many shapes and sizes, and a quick look at our review section will tell you that the price tends to vary less with these devices than with many other appliance types.

While you can go out and get yourself a garage heater for under a hundred bucks if you’re tight on cash – as with the Heat Storm Phoenix Floor to Wall Infrared Space Heater – most of our garage heaters are priced within the $100 to $200 price bracket –

such as the Mr. Heater 30,000 BTU Vent Free Blue Flame Natural Gas Heater MHVFB30NGT. Two exceptions to this would be the big DeWalt heater and the Mr. Heater MH25LP 22,000-BTU Propane Radiant Heater, which just about tops the 280 dollar mark.


Do the kerosene garage heaters give off carbon monoxide?

The key to safe operation with any kerosene-burning device is to make sure that there is adequate ventilation. In terms of your garage heater, what that means is supplying the heater with enough air so that it can adequately combust the kerosene fuel properly.

The process of burning kerosene will produce carbon monoxide, so it’s critical you have uninterrupted ventilation in order to make sure the heater functions well, and that carbon monoxide doesn’t build up in the space where the burning takes place.

How do you clean the unit?

As with any item of equipment, it’s vitally important that you read all of the guidelines and advice which the manufacturer specifies for a device before using or installing it.

Different products will require different considerations in terms of safety and prolonging the use of the equipment, and garage heaters are certainly no different in that sense.

Incorrect or inappropriate cleaning methods and substances can result in injury or in premature failure of a product, so it is always the best policy to take heed of any information that the manufacturer sends with your garage heater – before you undertake any maintenance or cleaning work.

Do wall-mounted heaters pose a fire risk to wallpaper?

It’s essential that you observe all the manufacturer’s instructions when you install your wall-mounted garage heater, and that includes any restrictions on materials and clearances.

Our Verdict

So there we have it, we’ve looked at the ten models and the best garage heater that topped our chart was the Dimplex DGWH4031G. We were impressed by this unit’s all-around ability to produce a hefty 13.640 BTUs of heating power and cover a massive area of up to 400 square feet. We think it’ll be a great addition to any garage.

The Dimplex DGWH4031G was followed closely by the Sengoku HeatMate HMN-110 in second place on our list. The Sengoku puts out a whopping 10.000 BTUs of heat and will give you a vast coverage area of up to 380 square feet, which is no mean feat.

In third place, and taking out our top pick for the best wall-mounted garage heater was the excellent Mr. Heater MH25LP, which produces a stunning 22.000 BTUs of heating power. Mr. Heater’s lofty position enables a coverage area of up to 550 square feet, which is remarkable given this unit weighs in at just three pounds.
