Best Garage Heaters for Cozy Workplaces (Reviews) in 2021

There’s nothing cosier than inviting the lads over for a well-earned pint in the garage after a hard day at work—unless you don’t have a heater in the middle of winter, that is.

Sure, you could probably make do with a small space heater in a pinch, but show your mates you care with a garage heater that does the job properly.

What are the best garage heaters?

If you’re the kind of person who enjoys DIY projects but can be scarcely bothered getting out of the comfort of bed because of the cool temperature, a garage heater will stave off the frostbite and let you get to work in comfort.

Based on our extensive research we found these to be the best garage heaters:

1. Garden Mile® 2Kw PTC Turbo Industrial Space Fan Heater

Price: £ | Dimensions: 16 cm x 20.5 cm x 32.2 cm | Heat Modes: Fully adjustable thermostatic control and dual heat mode | Watts: 2,000W | Material: Strong durable ABS plastic and metal | Finish: Black

Garden mile 2Kw PTC Turbo Industrial Space Fan Heater

Heaters capable of outputting this much energy are often seen (correctly) as being inefficient bank drainers. This model from Garden Mile, though, bucks the trend. While it probably won’t win any prizes for looks due to its rectangular-prism design, the PTC Turbo more than makes up for this with its industrial-grade performance.

Positive Temperature Coefficient is a special technology that opts away from resistance wire and instead uses ceramic stones or chips. In other words, PTC heaters will only create enough heat output to fill the desired space, keeping you comfortable and your bills reasonable. While running a powerful space heater on for many hours on end can waste a lot of energy and money, it’s a breath of fresh air that Garden Mile is designed with this in mind.

One thing to note, however, is that our testing indicated that the product is best used for a small workshop, not a cavernous garage. But considering this a 2,000-Watt unit on the low end of the price range, this is to be expected. All in all, this is fantastic value for money.

2. Large Parasene Electric Heater

Price: £ | Dimensions: 19.5 cm x 18 cm x 29 cm | Heat Modes: 2 | Watts: 1,000W or 2,000W | Material: Metal | Finish: Green

Large Parasene Electric Garage Heater

“Durability” is the operative word when it comes to this fantastic heater. It provides instant heat and features a convenient handle for easy portability. We’re not saying you should try, but the metal frame looks like it could stop a low-calibre bullet.

A fan is included for efficient heat distribution, and the unit itself is exceptionally easy to clean. Moreover, the unit itself is odourless and doesn’t cause humidity. Operation couldn’t be simpler, either: Half power or full power—it’s just that simple.

Keep in mind, though, that you will literally use double the power at its full setting, so we recommend using the half setting where comfortable to reduce both your energy bill and your carbon footprint. While this heater is designed for a greenhouse (thanks to its robust fan), it also makes for an excellent garage heater. The fan is efficient, lasts for ages, and doesn’t hog energy.

3. Kiam 2.5 kW Electric Infrared Heater

Price: ££ | Dimensions: 87 cm x 19 cm x 9 cm | Heat Modes: 3 | Watts: 850 – 2,500W (depending on setting) | Material: Quartz tube heating element | Finish: Black and silver

Kiam 2.5KW Electric Infrared Garage Heater

If a freestanding heater is what you’re after, it’s hard to look past this excellent unit from British-owned company Kiam.

Kiam has been around for more than a decade, and their expertise at designing mid- to high-range heaters is well regarded. While they are a bit higher price-wise compared to models of this power and type, quality is right at the top with an impressive 2,500 hours of lamp life and the capability of heating up an area of 25 m².

Suitable for both home and commercial use, this heater has 45-degree up-down functionality to ensure you can orient this heater however you like. As part of the package, you get a remote control and 24-hour timer. Best of all, you can use this outdoors with no worries; this is because it has a splash-resistant rating of IP34.

After testing, we found that even its lowest heat setting really crisps things up. Yes, it has overheat protection, but we seriously recommend starting with the lowest setting before working your way up as a precaution.

4. Hausen Electric Tubular Heater

Price: £ | Dimensions: Length (depending on model): 30.5 cm / 61.5 cm / 92 cm / 102.5 cm; Width: 3.2 cm; Depth: 1.27 cm | Heat Modes: 1 | Watts: 60W – 240W | Material: Plastic and metal | Finish: White

Hausen Electric Tubular Heater For Greenhouse Shed Garage

If you’re looking for a more passive heating solution, Hausen has you well covered. Offering four choices in length, there’s something here for everybody. This low-cost heater prevents condensation, damp, and freezing. It does this all with an IP55 waterproof rating, which is particular important if you want to use this is a greenhouse.

The Hausen‘s use in garages is also quite popular, as its low-power setting will ensure you can keep your garage toasty without your bank balance becoming toast. Stylistically, the tube is reminiscent of a fluorescent light—right down to the white colour.

With more than 40 ratings averaging 4.5 stars, this product has proven its usefulness in a variety of different scenarios. Additionally, all size variants come with a 1.5-metre cable and thermal protectors to keep you safe. Overall, Hausen has really put together an irresistible deal with this heater, offering a great-value product at an aggressive price point; moreover, they’ve managed to do it without compromising on quality and safety, which makes it little wonder that the product has sold so successfully.

5. Garden Mile® 3kW Industrial Space Fan Heater

Price: £ | Dimensions: 19 cm x 18 cm x 29 cm | Heat Modes: 3 | Watts: 3,000W | Material: Strong durable ABS plastic and metal | Finish: Black

Garden mile® 3Kw Industrial Space Fan Heater

We simply love the look of the Garden Mile® 3kW Industrial Space Fan Heater — it has a sturdy handle for portability and is finished with a beautiful design that is borderline minimalism. This isn’t the first time that Garden Mile has featured on this list—and for good reason.

This particular unit can heat a mid-sized room rapidly and easily, meaning your garage will never have to be the cool part of the house again if you don’t want it to be. This product has been around since 2012, which for our money is a sign of reliability and a case of “if it ain’t broke, don’t fix it.”

6. Economy+ Electric Radiator

Price: £££ | Dimensions: 486 mm – 1296 mm | Heat Modes: Programmable | Watts: 560W – 1,960W | Material: Silica-filled with ultra-durable exterior | Finish: White

Economy+ Electric Radiator - Electric Heater

Made in Britain, this luxury electric heater will save you money in the long run due to its efficient and effective heating ability. There’s a good chance that this heater is the most energy-efficient heater on this entire list, so we’d so to keep this in mind if you’re able to make the long-term investment.

One thing that really appeals to us is the fact that it is handmade. Yes, that’s right–artisanal heaters in 2020! Best of all, it comes with a two-year warranty.

The largest variant, the 1296-millimetre-wide one, weighs approximately 21 kg, although the fact that it is a wall-mounted heater should render this moot unless you plan on affixing it to a paper-thin wall. Installation is really easy, too. All you need, according to the manufacturer, is a spirit level, pencil, drill bit, and a drill, although I’m sure you can always pay a professional installer if the idea of drilling into your wall yourself turns you whiter than the heater itself.

Garage heater buying guide

Here below, we guide you through the critical thought process you need to ensure the most effective buying decision for your purposes.

Determining value, efficiency, and quality

Input determines output. A lot of details should be carefully considered when looking for an appliance that warms or cools the house.

The size of the heater, your source of power, and the intensity applied in heating the air are the major efficiency determinants. However, energy efficiency cannot be determined from these factors alone. Consider the following factors as well:

  1. Size of the heater

It is common sense that bigger heaters will require more energy consumption. It is therefore wise to settle for smaller heaters where smaller heaters will suffice. Garage heaters are usually going to require more power to run than electric space heaters designed for the home or office, so you should bear this in mind when budgeting for your next heater.

A bigger heater simply means additional features to power. Also, bigger heaters tend to be more basic in terms of their construction. Smaller heaters tend to be more advanced in technology in order to maintain efficiency. That being said, it should be mentioned that larger heaters overall will almost always be more efficient overall, as their large size can distribute heat more evenly and with less power overall.

  1. Portability

Different heaters have varying degrees of portability. While some heaters can be mounted on walls, others cannot. It is possible to move some heating appliances from one location to another, while it is impossible or inconvenient to move others. For garage heaters, make sure a wall-mounted heater will not interfere with cars or other items you may store inside the garage.

  1. Capacity

While efficiency in humans is measured with time, it is the ratio of output to input in machines. When thinking about an energy-efficient heater, consider the relationship between input and output.

A heater that uses a lot of energy to give a high output may be more efficient than one that uses less energy to produce less. At any rate, ensure you choose a heater that is not wasteful. For garage heaters especially, it’s a good idea to try to keep your heater on the lowest setting that makes you comfortable. Overheating is wasteful, expensive, and potentially dangerous.

  1. Safety features

A heater, just like any other electrical appliance, is likely to become defective after a period of time. As such, safety features are there to protect you if a fault should occur.

The more safety features a heater has, the better. Auto shut-off in case of extreme temperatures is one of the important features to look out for, while it is crucial that portable heaters that are susceptible to falling over have a tip-over switch.

Having the power to control your device’s output also minimises the chances of accidents occurring. Remote controls and other advanced features are also important things to consider.

  1. Adjustability

How much control do you have over your heater? How wide are your options? The settings should give you a wide array of options to ensure safe and efficient operation at all times. A programmable heater, as mentioned above, will allow you to control the temperature to the precise degree, assuring an unsurpassed level of comfort.

Rapid weather changes might give you problems, and garages are particularly susceptible to dropping in temperature due to poor insulation. Therefore, you want a heater that allows you to adjust dynamically according to the changes taking place.

  1. Energy-saving features

It is not just about the heater’s efficiency; how much freedom does it give you to save more energy? It is essential to look out for energy-saving features like a thermostat, remote control, timer, ability to program, and many others.

It is imperative that you can turn your devices off when you do not need them or when you’re outside your house. When living in a house with a lot of rooms, how decentralised is the heater? Does it allow you to switch off the heaters in the other rooms?

More essential factors to keep in mind

It’s not all numbers, you have to think holistically how this heater will come into your life through purchase, as well as how it will physically fit into your home.

Space and size

You cannot buy just any type of heater. The appliance must have the capacity to match the work at hand. Go for more powerful heaters when you have a bigger room to heat. A big space may require you to buy a heater that allows mounting. Some heaters lack mounting features.

According to our research, your seller will provide you with details of how far your heater will warm the room. Some buyers ignore these details and end up with unfulfilled expectations. We do not want the same to happen to you.

We believe matching your living area with the right heater will achieve excellent results.


Well, it is advisable to go shopping with the exact item you want to buy in mind. The only problem is the dynamic nature of the marketplace. It is almost impossible to find the exact product as you want it. That is why you need to keep an open mind and consider buying online.

Now, open-mindedness doesn’t mean simply buying the first thing that catches your eye. The best thing to do is to know your options. Assessing your options carefully will allow you to settle for the right alternatives.

Once you know what suits your space and budget, finding out the alternatives are available in the market will save you energy and time.

Evaluate your options and only make a purchase once you’re certain that is the better option. This article has highlighted the best energy-efficient space heaters options on the market right now.

How to efficiently use a garage heater

Best Garage Heater

Despite the marketing, there’s a bit of a knack required beyond “set it and forget it” to get the most out of your heater.

Read the details of your manual

The first step to a successful appliance application is mastery of the instructions. Once you have the details with you, it is now time to start exploring.

You should have a good idea of what to do in hazardous situations. Not only that, in case of an accident, what should you do? Who should you call for assistance in case you are in need of assistance? In the event of a fire, do you have adequate gear on hand to put out the fire?

Most buyers overlook these aspects. Remember, different products have different advanced features, which only the manual can fully explain.

Every manufacturer is legally obliged to contain safety and correct operation information in these manuals, which is why we advise you not to skip any details.

Select heating method

Various heaters come with different heating methods. This selection alone has the power to decide the level of energy efficiency your heater achieves.

For instance, imagine heating all your rooms when you typically only spend time in a single room. Wouldn’t that be a waste of energy?

Deciding to heat occupied rooms alone—and only when necessary—will save you thousands of pounds annually on your electricity bill.

Make full sense of the heating controls

Heating controls are made to improve your user experience. If well utilised, it will save you energy, time, and money. It will also protect you from potential safety hazards. Below are some of the controls you must utilize.

  • Remote control

Imagine leaving your seat every time to adjust your heater. It is annoying and inconvenient, especially when you are busy doing your things. This is where a remote control comes in handy. Like a TV set, it allows you to switch the heater into a setting of your preference.

  • Timer

This is another important feature you could take advantage of. With a timer, you can arrange for your heater to go off or turn on at specific times. This will save you a considerable amount of energy in the long run.

  • Thermostatic valves

A thermostat allows you to automatically maintain a desirable level of heat. This is a particularly effective feature, especially in cases where only a few of your rooms are used.

Tips for positioning your garage heater

Heater positioning is critical, especially in a garage. It also must be practical. For example, you should not keep a heater meant to be kept outside in your house. Another example of good positioning is using a garage heater inside a small single room. You may burn yourself or start a fire.

New purchases come with a manual–the best thing to do is to follow the step-by-step instructions. Garage heaters are often designed with industrial use in mind, so they are often built to be sturdier and with capacity for higher temperatures. This is a double-edged sword, as careless use of high-capacity heaters are more likely to start a fire.

Garage Heaters: The Bottom Line

Like space heaters, garage heaters are highly dependent on the needs and budget of the user. Regardless of which heater you choose, it is best to ensure you select an energy-efficient heater that perfectly fits for your needs. Adjustability, portability, capacity, safety features, and effectiveness should also factor into your final decision.

You also have a responsibility to control your device’s efficiency level after purchase. We encourage you to make use of your heater’s controls to manage power consumption. Durability is especially important for garage heaters, which is why many of the products on our list were chosen specifically for their toughness.
