1 Kismile: Radiator Heater – Best Budget Garage Heater

Let’s get things started with the Radiator Heater by Kismile. This is an oil-filled radiator-type heater. The unit can pull up to 1500 watts and uses this electricity to heat up the oil that circulates in its steel fins. These fins then radiate heat like, well, a radiator.

This is a really inexpensive machine, costing a little over fifty bucks. With three power settings of 600, 900, and 1500 watts, you shouldn’t expect it to heat up a whole two car garage from freezing to a comfortable room temperature. Far from it. Instead, this affordable unit will just help to raise the room temperature of a small space to make it more comfortable for working, cleaning, or just tinkering around.

Is this garage heater right for you?

This is a simple electrical appliance that runs off a standard 120 volt plug. It has sturdy caster wheels and a six foot cable, which makes it quite easy to move around the garage and fit into whatever space you need. There’s no actual temperature setting on this heater. Not with degrees, anyway.

It simply has a relative heat knob you can adjust and wattage switches. The switches are a bit confusing. Labeled I and II, they give level 1 and 2, and if you flip them both on, you get 1+2=3!

You’ll get used to it…

And while the radiator fins get really hot and untouchable, it has some good built-in safety features. These include an automatic shut-off if the heater tips over 30 degrees, as well as an overheating protection shut off.

It’s cheap and warm, but you do need to sit next to it. It won’t do much heat a whole garage, but if you need it when you’re at your workbench, this unit will do the trick.

Size: LWH 9.4″ x 13.1″ x 24.6″

Kismile: Radiator Heater

Our rating:3.9 out of 5 stars (3.9 / 5)


  • Inexpensive.
  • Heat level is adjustable and provides good heating if you’re close to it.


  • Low power can’t heat a full garage.
  • Fins can get really hot.

2 Optimus: H-9010 Electric Garage Heater – Best Wall Mounted Garage Heater

Coming up in price just a bit is the H-9010 Electric Garage Heater by Optimus. This is a very different heater in that it’s designed to be mounted from a bracket either on the wall or the ceiling. This is a quartz radiant heater with two elements that put off quite a bit of heat.

Let’s look at some specs…

This little unit can be set to run off 750 or 1500 watts and converts this into a fair amount of heat. In fact, we’d say you need to be a bit careful about what you put within about 3 feet of this heater because it gets HOT. Still, it has an internal overload protector to shut off the machine and keep it from melting down.

The machine is pretty easy to use. You can swivel the heater around when needed by grabbing the sides. They don’t get too hot to touch. And a single pull cord is all it takes to turn it off and on or change the wattage.

Lighten up your day…

On top of a small running light, it also comes with a halogen lamp to give you some extra light. If you’re imagining putting this over your workbench so you can heat up your mitts and see what you’re doing, so are we.

On the downside, this is only a 1500 watt maximum machine. Once again, you can’t expect it to heat up a whole two-car garage, but over a work area, it would be nice. Of course, you need an outlet nearby, as the heater only comes with a relatively short 3-foot cord.

And, of course, an overhead heater isn’t the most efficient. You’ll lose a fair bit of the heat generated as it rises up to the ceiling.

Size: LWH (W x H x D): 23” x 6” x 15”

Optimus: H-9010 Electric Garage Heater

Our rating:4.4 out of 5 stars (4.4 / 5)


  • Affordable.
  • Generates intense heat close by.


  • Can’t really heat a big garage.
  • Comes with a disappointingly short cord.

3 Aireplus: 1500W Electric Heater – Best Radiator Garage Heater

With another small increase in price, getting close to 100 bucks, we’re back to an upright oil-filled radiator-type heater. Aireplus brings us their 1500W Electric Heater, and you’re going to think what we’re thinking.

Isn’t this the same as the Kismile?

Sure, at first glance, it looks pretty much the same. It’s black, but other than that, it’s a tall radiator-type heater on four wheels. It also runs on up to 1500 watts. And like the Kismile, it uses steel fins to radiate heat throughout the room.

But that’s where the similarities start to run out…

While the Kismile has some clunky switches and an analog knob to control the temperature, the Aireplus heater has gone digital. It’s got a large screen, easy-to-read digital display to show you the temperature it’s running at. And this temperature can be adjusted with the buttons on the heater or with the included remote control.

It still has the three electric levels of 600, 900, and 1500 watts, but things are much more refined here. You can adjust the temperature from 40-95 degrees. There’s also an ECO mode to help you save on electricity by allowing the built-in thermostat to keep the temperature consistent. And you’ve got an up to 24 hour on/off timer, so you can just set it and forget it.

For safety…

The Aireplus has a child lock function, an overheating shut off, and a tip-over protection shut off. This heater keeps the temperature consistent in a smaller space, but may struggle in a larger garage. It has the benefit of running really quietly. And we found the digital screen really easy to read and adjust.

Size: LWH 6.45” x 15.3” x 26”

Aireplus: 1500W Electric Heater

Our rating:4.5 out of 5 stars (4.5 / 5)


  • Inexpensive.
  • Convenient controls and temperature settings.


  • Not powerful enough to fully heat a big garage.
  • Radiator fins can get extremely hot.

4 Comfort Zone: CZ220 Fan-Forced Ceiling Mount Heater – Best Ceiling Mount Garage Heater

ComfortZone is a company just begging for puns, but we won’t take you into or out of that situation.

We’re not that sort of folks…

The company is also begging for us to take a look at their heaters CZ220 Fan-Forced Ceiling Mount Heater. This is a really different sort of machine all over again. For a bit over a hundred bucks, we’re suddenly looking at a heater that can run on 3000, 4000, or even 5000 watts of pure blazing heating power.

This is a commercial-style machine designed to really heat up whole spaces, not just heat a person sitting nearby.

If you’ve got a garage nearing 500 square feet, this is about the size of heater you’ll probably need. Running up to 5000 watts, though, requires some special wiring. This unit needs to be hardwired into a 240-volt power supply and a minimum 30 Amp breaker. Unless you’re an electrician, plan to hire a professional to do this for you.

The heater itself is really affordable, but the power supply may not be…

The CZ220 is meant to be mounted on the wall or ceiling and comes with a heat-resistant bracket for this purpose. It has louvers on the front that you can use to aim the heat in the right direction. The whole thing is in a heavy gauge steel casing that looks pretty darned durable.

The machine is solid and dependable but a bit noisy. Also, these aren’t the best controls we’ve seen. There’s a 3-position wattage switch and a knob to turn up and down to control the relative heat. But there’s no display and no actual temperature settings.

It’s also quite hard to use these controls if you’ve gone and mounted the heater on your ceiling or high up the wall. Have a broom handle ready!

Size: LWH 17.88” x 14” x 14.5”

Comfort Zone: CZ220 Fan-Forced Ceiling Mount Heater

Our rating:4.5 out of 5 stars (4.5 / 5)


  • Inexpensive and very powerful.
  • Can heat up to 500 square feet.


  • Makes a bit of noise.
  • Not easy to control.

5 Key Tek: Electric Infrared Heater – Best Infrared Garage Heater

Next in our Best Garage Heaters reviews, we have a model from Key Tek – their Electric Infrared Heater. And while this is more billed as a patio heater, it can certainly also be used in the garage. Design-wise, this heater is like the Optimus if it was squished flatter and stretched longer. We really like the long, sleek design of this heater, which comes in both silver or black colors.

The casing is aluminum, which is durable and rust-proof. It has an IP55 rating, which you’d love to see on your wireless earbuds. This means it has level 5 ingress protection against both dust and water, so it can basically be rained on, and it will do fine. Not your biggest concern in the garage, though.

What else did we love?

What’s great is that the long, thin design allows it to be fixed to a beam of crosspiece quite easily. You haven’t got any temperature controls here, though. Instead, you can just set the wattage to 500, 1000. Or 1500 watts.

Of course, you don’t have to climb on the furniture to do this. The Key Tek comes with a remote control to set the power setting that has a range of about 6 yards. There’s also an indicator light to let you know if it’s on or not.

Or else the heating elements might let you know! Though this isn’t the most expensive heater by any means, it’s also not the most powerful either. And the extra cost above the competition comes from its outdoor ratings. It is quiet and looks cool, though!

Size: LWH 26.77” x 5.91 x 7.09”

Key Tek: Electric Infrared Heater

Our rating:4.4 out of 5 stars (4.4 / 5)


  • Sleek, attractive, and… waterproof?
  • Easy to control with its remote.


  • No temperature controls.
  • Not powerful enough to fully heat a garage.

6 Infrared Heater: DR-988A Infrared Garage Heater – Best Rated Garage Heater

We have a total of three heaters on our list from one manufacturer – Dr. Infrared Heater. The first is a simple, industrial-looking box heater designed to be placed on the floor or possibly on a (heat resistant!) counter. This is a more efficient design compared to an overhead heater since heat rises anyway. At the same time, though, it could take up valuable floor space in your garage.

This is an infrared radiant-type heater with a fan to force air around your space. And that space can be anywhere up to 500 square feet. After all, this heater runs on a choice of 4800 or 5600 watts.

That’s some heating power!

The unit has a built-in electronic thermostat that can help to keep your garage anywhere between 45 and 90 degrees. It also has overheating protection built-in so that you can be assured of its safety. Another safety feature is the small-hole finger-proof intake and discharge grills on the front and back of the heater.

They’ll even protect against little fingers getting into the fan; however, the front grill gets so hot that it could burn fingers instead.

Now the news that might be hard to swallow…

Because this heater takes so much power, it needs a special 240-volt outlet, a 6-30R Plug. This has to be wired into a double pole breaker, and the company recommends 30 Amps. So while the heater is very affordable, like the ComfortZone we saw earlier, it may cost you a lot more in electrical set-up.

Once again, this heater lacks specific temperature settings and a display. Instead, it has an analog knob to help you turn the heat up and down. And because it’s a forced-air heater, it’s pretty noisy. But at least it has the power to heat up a standard-sized two car garage.

Size: LWH 12” x 12” x 16”

Infrared Heater: DR-988A Infrared Garage Heater

Our rating:4.3 out of 5 stars (4.3 / 5)


  • Good price for a powerful heater.
  • Efficient floor heater style.


  • Requires special outlet.
  • Makes a fair bit of noise.

7 NewAir: NGH500GA00 Garage Heater – Best Portable Garage Heater

Throw in around 20 more bucks, and you can pick up the NewAir Garage Heater. This is also a powerful unit, though it only runs up to 4800 watts compared to Dr. Infrared Heater’s 5600 watts.

Once again, the power of this unit requires that its 6-30R plug is plugged into a dedicated 240-volt outlet. You’ll need that 30 Amp breaker as well. This heater is designed to be placed on the floor for efficiency or hung suspended from a bracket to keep it out of the way. And yes, that bracket is included.

So what else is different?

Aside from the choice of mounting systems, the NewAir has some extra features when compared with the Dr. Infrared Heater machine. First off, it has a digital display and controls on the front, allowing you to set your desired temperature with the push of a button.

But on top of that, it comes with a remote control. This is essential if you’ve installed it up high because otherwise, it would be hard to access the controls.

You can also adjust the fan speed. Low speed is useful if you’re working in the garage and want to have the heater on you without being too powerful. High speed can help to heat your garage quickly and evenly.

Not a quiet option…

Now, this heater is definitely enough to heat a double garage, but it may struggle with a triple car garage. It’s also moderately loud and may drown out the noise of music or videos if you’re using it while working on some self-study projects.

Size: LWH 10.3” x 10.8” x 13.7”

NewAir: NGH500GA00 Garage Heater

Our rating:4.1 out of 5 stars (4.1 / 5)


  • Powerful heater.
  • Good price for a digital display and easy controls.


  • Runs moderately loud.
  • Requires extra cost of wiring a 240 volt outlet and 30 Amp breaker.

8 Infrared Heater: DR966 240-volt Hardwired Garage Heater – Best Commercial Garage Heater

We’re back with another Dr. Infrared Heater machine. Let’s see how the DR966 compares with the DR-988A we saw earlier. Once again, we’re looking at a coil-style heating unit with forced air to push the heat around the room.

Heating efficiency…

The heating coils in this heater are thin and efficient, pumping out hot air quickly with the help of the 8-inch fan inside. Again, it has a finger-proof grill on both the front and the back.

Also, on the front of this unit, we see five independently adjustable louvers to help you guide the heat you need to specific parts of your space. These are particularly useful when the unit is installed as an overhead heater on the swinging handle it comes with. But it can also be placed on a garage floor with the louvers directing air up to where you’re working.

What makes it different?

Well, like its cousin, you’ll need a 240 volt supply, and in this case, a 35 Amp breaker because of the more powerful fan. But this heater has no power cord and is intended to be hardwired to the breaker.

The whole unit can run off a choice of 3000 or 6000 watts, so it’s a bit more powerful than the DR-988A. This combination helps it heat a garage up to 500 square feet faster and more consistently.

However, it also runs quieter, which is a plus. Where it could use improvement is in the controls. These are basically the same as the DR-988A, but here the DR966 really is intended as an overhead heater. If you have it mounted high up the wall or on the ceiling, it will be hard to access the analog temperature control knob.

Size: LWH 14.5” x 13” x 14.5”

Infrared Heater: DR966 240-volt Hardwired Garage Heater

Our rating:4.5 out of 5 stars (4.5 / 5)


  • Powerful but relatively quiet heater.
  • Has no problem heating a large space up to 500 square feet.


  • Requires an extra investment in hardwiring to 240 volts.
  • Controls are not easy to access if mounted overhead.

9 Infrared Heater: DR975 Electric Garage Heater – Best Premium Garage Heater

Let’s turn up the heat with our third and final Dr. Infrared Heater unit. At first glance, the DR975 looks a whole lot like the 6000 watt DR966 model. But looks can be deceiving. The DR975 runs on 7500 watts of electricity, meaning it has the extra heating power to warm a space of up to 750 square feet. This could heat a three car garage or even a medium-sized commercial garage.

Again, this unit can be placed on the floor, but it’s really designed for overhead mounting and comes with a bracket and swing handle for that purpose. This time, though, Dr. Infrared Heater has given the heater a remote control and a digital display. That makes it so much easier to control and adjust the temperature.

Manual re-set…

This could be a small issue for some users. While the DR966, being hardwired, will just come back on after a power outage, the DR975 won’t. It requires a manual re-start with the remote control should it ever lose power. So if you live in an area where outages can happen often, and you need to rely on this heater to keeps things warm at all times, be warned!

This heater also has to be hardwired and doesn’t come with a power cord. You’ll need to supply 240 volts and this time a 40 Amp breaker because of the extra power it can draw. You’re also getting a higher-quality, fully-encased motor here, so that helps to justify the extra cost over its less-powerful relatives.

Not the most accurate…

One complaint we had, though, is that the temperature settings are not very accurate. They could be off by as much as 10-15 degrees, so be aware and turn up the heat accordingly.

Size: LWH 15” x 19” x 13”

Infrared Heater: DR975 Electric Garage Heater

Our rating:4.3 out of 5 stars (4.3 / 5)


  • Very powerful machine for a good price.
  • Runs quietly and has a fully enclosed motor.


  • Requires hardwiring to 240 volts.
  • Temperature settings aren’t very accurate.

10 Dyna-Glo: EG7500DH Dual Heat Electric Garage Heater

We round up our review of the best garage heaters with the Dyna-Glo EG7500DH Dual Heat Electric Garage Heater. Like the Dr. Infrared Heater DR975, this is a machine intended to be overhead mounted and hardwired to your power supply. It can draw 5000 or 7500 Watts on two different settings. This provides the power to heat a space of up to 750 square feet.

Quieter than some…

This heater has a fully enclosed motor and runs very smoothly. It’s a little bit quieter than the Dr. Infrared Heater 7500 model. It also comes with an LED touch screen and display, as well as a remote control for setting the temperature. But like the Dr. Infrared Heater, its temperature settings aren’t terribly accurate.

The louvers on this machine can also be independently angled for vertical control of where the heat goes. However, the whole unit can be set up at any angle to get heat where you need it. This is great for the garage workshop or even a commercial mechanic’s space.

So what are the downsides?

Well, like the other heaters we’ve seen at 5000 Watts or over, this heater can’t run off your home’s normal 120 volt plugs. It doesn’t come with a power cord and needs to hardwired to a power supply. You’ll need to invest in 240 volts and a 40 Amp breaker, and maybe the professional help to install it.

After that, though, the unit should run dependably for years with really little or no maintenance.

Size: LWH 14” x 10.63” x 12.63”

Dyna-Glo: EG7500DH Dual Heat Electric Garage Heater

Our rating:4.1 out of 5 stars (4.1 / 5)


  • Heats a big space up to 750 square feet.
  • Runs smoothly and relatively quietly.


  • Most expensive heater.
  • Requires extra cost of hardwiring installation.

Best Garage Heaters Buying Guide

Best Garage Heaters Buying Guide

You’re cold and shivering while trying to work in your garage. You know you need a heater, but which one do you choose with so many types and sizes available?

Never fear; our garage heater buying guide is here!

Heating Coverage and Power

The first thing you need to decide is what sort of heating you need. Are you trying to heat your whole garage to a comfortable temperature, or are you looking for a heater that will just keep you warm while you work in the garage?

Small garages

If you have a small, single-car garage, you may be able to get away with a 1500 Watt heater. Even then, though, it will struggle to keep the space heated to a consistent temperature unless you have excellent insulation. This size of heater will keep you warm, though. Just point it at yourself while you’re working, and you’ll stay toasty.

Large garages

If you have a large garage for two, three, or more cars, you’ll need a lot more power. A 5000 Watt heater is generally sufficient to heat up and maintain a comfortable temperature in a standard two car garage. But if your garage is bigger than that, look to the 7500 Watt big boys. These heaters should be able to keep the temperature consistent even when it’s freezing outside.

Mounting and Installation

Big heaters, though, require extra installation work. While a 1500 Watt heater can simply be mounted and plugged into your home’s 120 volt outlets, a 5000 or 7500 Watt heater is a different animal. These big heaters use lots of electricity and require extra safety measures.

They either come with 240 volt rated plugs that you’ll need special outlets for, or need to be hardwired. You’ll need a dedicated 30-40 Amp breaker for safety as well.

This extra installation can mean a whole lot of extra cost if you’re not a trained electrician. The heaters might be cheap, but you’ll need to add in the extra wiring costs.


Floor-based heaters are more efficient and will save you money on heating in the long term. Because heat rises, overhead heaters will waste a fair bit of energy heating the space above your head. If your garage is under the house, though, this heat won’t go to waste.


If you’re going to put your heater on the floor, a simple control panel is going to be just fine. For overhead heaters, though, simple switches are going to be hard to access. A pull-cord switch is good, but a remote control and easy-to-read digital display is better!

So, what are the Best Garage Heaters?

While we got the chance to look at some of the best heaters for garages out there, one stood out for us. While smaller units can keep you warm, we had to choose a heater that would keep the whole garage warm, and that meant more power.

That’s why we went for the…

NewAir Garage Heater

This was the ticket for us; you’re getting 4800 watts of power here, with a choice of floor or overhead mounting. The powerful heater has a digital display and a convenient remote, and does a great job of heating a two car garage.

Whichever heater you choose, you’ll be glad you invested in heating your garage to make it a convenient and comfortable workspace.

Happy tinkering!
