Best Garage Heaters

Comfort Zone Electric Heater

The Comfort Zone Garage Heater is a solid choice for those wanting to keep their garage warm during winter projects. 

With its 10,000-watt heat output and compact design, it can handle most two-car garages or workshops without taking up valuable floor space. 

There are also different wattages available for this model, meaning you can get a smaller wattage model if your garage is smaller, and vice versa.

This hardwired electric garage heater mounts on the wall or ceiling, making it an ideal option for a cluttered workspace. Its adjustable louvers let you direct the heat where you need it, and the built-in thermostat ensures you don’t overheat while tinkering under the garage door.

If you’re tired of dragging around propane tanks, this electric model eliminates carbon monoxide worries.

During testing, this forced-air garage heater warmed a 20×24 garage from 48 to 60 degrees in under half an hour. The fan is quiet, allowing you to work in peace. Cleaning is straightforward thanks to a removable shroud, perfect for garages that collect sawdust or dirt.

It’s not without its flaws. The 220-volt requirement means many users will need to hire an electrician to install it. Additionally, the thermostat isn’t precise, so don’t expect it to match your home thermostat’s accuracy.

For those seeking the best garage heater for a medium-sized space, this heater offers excellent performance for the price.

But if you’re heating a larger space or need pinpoint temperature control, consider upgrading to a 10,00-watt model with a digital thermostat or exploring infrared garage heaters for zoned heating.

Whether you’re working on winter projects or just keeping the chill at bay, this heater will get the job done.

Mr. Heater F260550 Big Maxx MHU50NG Natural Gas Heater

If you’re searching for the best garage heater to keep your space warm all winter, the Mr. Heater Big Maxx is a top pick.

Designed for larger areas, this natural gas heater offers robust heat output for garages and workshops. With multiple BTU options, it can warm everything from a two-car garage to a sprawling workshop.

I tested the 80,000 BTU model, which quickly raised the temperature in my 500-square-foot garage from 40°F to a cozy 70°F in under three hours. It’s perfect for working on winter projects without freezing fingers.

This forced-air space heater mounts easily in a corner of the garage, keeping your floor space clear. Using natural gas as its fuel source, it runs more affordably than most electric garage heaters.

Installing the unit is straightforward. A professional HVAC tech handled the gas line and vent kit for me, but DIYers with experience could tackle this. Just make sure you maintain proper clearance to avoid issues with carbon monoxide.

Noise-wise, it’s quieter than expected. The forced-air heater hums along without making a racket, even when running full blast. If you’re someone who likes to leave the garage door open occasionally, the Big Maxx’s rapid heat recovery ensures you don’t feel a chill for long.

One downside: it’s not the most efficient option for a poorly insulated garage.

For anyone with a garage or workshop, this heater offers excellent value. It’s not flashy, but it gets the job done, keeping your tools—and your toes—warm all winter.

Senville LETO Series Mini Split Air Conditioner With Heat Pump

When it comes to efficient ways to heat and cool a garage or workshop, the Senville LETO Series Mini Split stands out.

Whether you’re battling summer heat or winter chills, this unit delivers consistent performance without the hassle of traditional garage heaters.

Let’s talk heat. The Senville blows a toasty 122°F air in heating mode, making it a serious contender for warming your garage during winter.

It’s a 1.5-ton system with a 19 SEER2 rating, meaning it’s efficient enough to handle larger spaces without draining your wallet. Compared to propane heaters or kerosene options, the Senville offers a cleaner alternative without the risk of carbon monoxide.

Installation isn’t for the faint-hearted, though. While physically mounting the unit is straightforward, you’ll need proper tools for the refrigerant lines.

What’s impressive is how quiet it is. At 30 dB, you’ll barely notice it running, even with the garage door open. Pair it with Alexa for smart home integration, and you can control the unit without stepping away from your workbench.

For anyone who’s tested garage heaters, the Senville feels like a leap forward. You’re not just heating your garage—you’re upgrading it.

If your garage is insulated, it can replace forced-air heaters or bulky propane tanks with something sleeker and smarter.

Sengoku Indoor & Outdoor Kerosene Heater

If you’re serious about heating your garage or workshop, the Sengoku Indoor & Outdoor Kerosene Heater is an option worth considering.

This kerosene heater delivers 23,500 BTUs, enough to heat a two-car garage with ease. I tested it in my garage during a brutal December night, and it turned a bone-chilling space into a toasty refuge within minutes.

The radiant heat feels like sitting near an infrared heater—direct, effective, and consistent. It’s portable, too, which makes it great if your workspace changes.

Unlike a hardwired electric garage heater or natural gas heaters that require installation, this heater is ready to go straight out of the box. The 1.9-gallon tank lasts for up to 12 hours, which is plenty for a full day of working on a project.

There is a slight kerosene smell when you start or shut the heater off, so proper ventilation is a must. Crack the garage door or open a vent to keep the air fresh.

The safety features, including the tip-over switch and overheat protection, offer peace of mind while you work.

Compared to propane heaters or forced-air options, the Sengoku doesn’t blow hot air; it radiates warmth evenly. You don’t need a propane tank or a gas line, and it’s cost-effective for larger spaces.

If you’re debating between this and an electric garage heater, remember—kerosene offers a high heat output without the 1500W ceiling of most plug-in units.

Mr. Heater MHVFBF30NGT Blue Flame Natural Gas Heater

The Mr. Heater MHVFBF30NGT 30,000 BTU is the kind of heater you’ll appreciate when your garage feels like an icebox.

Whether you’re fixing the car, tinkering with tools, or just hanging out, this natural gas space heater does the job.

It pumps out up to 30,000 BTU, easily heating spaces up to 1,000 sq ft. That’s enough to warm your garage or workshop without needing a propane tank.

Its thermostat makes adjusting the temperature effortless, keeping your garage at just the right level—no more fumbling with settings while your hands are freezing.

A feature you don’t see often is the low oxygen safety shut-off system. It gives you peace of mind, especially when heating your garage during winter.

That said, proper ventilation is still a must. Even with its safety measures, keeping a carbon monoxide detector nearby is smart.

What sets this heater apart is the blue flame convection technology. It spreads warm air evenly, unlike those infrared heaters that only heat objects directly in front of them. 

For anyone with a two-car garage or larger space to heat, this is a cost-effective option for heating without the hassle of electric heaters or kerosene fumes.

You’ll stay warm all winter without breaking the bank. Keep the garage door cracked for airflow, and this heater will get the job done.

Shinic Electric Ceiling Mounted Infrared Heaters 

If you’re hunting for one of the best garage heaters to keep your space warm this winter, the Shinic 2 Packs Electric Garage Heaters are worth considering.

These electric garage heaters combine simplicity and effectiveness, offering a solid heat output of up to 5120 BTUs.

Whether you’re working on a project in your workshop or relaxing in a two-car garage, these heaters ensure you stay comfortable even during the harshest winter days.

The radiant heat technology warms objects and people directly, which is especially useful if you’re within 10 feet of the heater.

Unlike propane heaters or kerosene heaters, there’s no need for a propane tank or ventilation, making it a cleaner and safer option. It’s also ETL-listed, so you can trust its safety standards.

One feature that stands out is the built-in halogen work light, which should be useful when working late.

Installation is straightforward, though some users noted that the mounting brackets feel a bit flimsy. On the bright side, their 90-degree tilting bracket lets you direct heat exactly where you need it, whether you’re warming up a workspace or heating your entire garage.

For larger spaces, you might need two units to distribute warmth effectively. If your garage door is frequently open or your garage isn’t insulated, these heaters still perform well but may take longer to reach your desired temperature.

While natural gas heaters or forced-air heaters have their place, these Shinic heaters offer a convenient, cost-effective solution for smaller to medium spaces, especially if you’re looking for something to install quickly and use right away.

Mr. Heater F299730 Blue Flame Propane Heater

If you’re looking for the best garage heater, the Mr. Heater F299730 Blue Flame Propane Heater deserves attention.

This thing cranks out a solid 30,000 BTUs, which is enough to heat up to 1,000 square feet—plenty for a two-car garage or a spacious workshop.

Whether you’re tackling winter projects or just trying to keep your car garage comfortable, this heater delivers reliable warmth.

What makes it stand out is its fuel efficiency. Using natural gas or propane, it provides radiant heat that feels like the sun on your skin, without skyrocketing your utility bills.

The thermostat control? It’s precise. You set it, and it keeps the temperature steady, so you’re not constantly fiddling with it.

This heater is versatile, too. Wall-mounted or freestanding, it adapts to your space. I’d recommend pairing it with a fan kit to circulate warm air more effectively, especially in larger areas. 

Now, here’s the juicy detail. Some users noticed a faint natural gas odor during ignition. While not a dealbreaker, it’s something to consider, especially if you’re sensitive to smells.

Also, the top-mounted controls can be tricky to reach when wall-mounted, so keep that in mind when deciding placement.

For anyone trying to heat an attached garage, this is a cost-effective option for larger spaces. Just make sure you’ve got good ventilation and a carbon monoxide detector. It’s a solid choice to keep your garage warm all winter long without breaking the bank.

Types Of Garage Heaters

Electric Garage Heaters

Electric garage heaters are a popular choice for their ease of use and safety. They require minimal setup—often just plugging into a standard outlet—and are virtually maintenance-free.

These heaters are ideal for small to medium-sized garages and offer precise temperature control, making them convenient for maintaining consistent warmth.

They also pose no risk of harmful fumes, making them a safer option for enclosed spaces. However, their main drawback is cost. Electricity is generally more expensive than other fuel sources, which can lead to higher operational costs, especially if the heater runs frequently. 

Propane Garage Heaters

Propane heaters are known for their high heating power, capable of quickly warming large garages. They are portable, with freestanding models that can be easily moved to target specific areas.

 Propane is often a more affordable energy source compared to electricity, making these heaters a cost-efficient choice. However, they come with certain safety considerations.

Because propane combustion produces carbon monoxide, adequate ventilation is crucial to prevent hazardous buildup.

Additionally, propane heaters require regular refilling of tanks, which can be inconvenient for users who prioritize low-maintenance solutions.

Natural Gas Garage Heaters

Natural gas heaters are an efficient and cost-effective option for garages connected to a natural gas line. They provide powerful and consistent heat, making them suitable for large spaces or extremely cold environments.

Once installed, they offer a low-cost and hassle-free heating solution. However, the initial installation can be expensive and may require professional help.

These heaters are fixed in place, limiting portability, and they also require proper ventilation to safely handle combustion byproducts.

Infrared Garage Heaters

Infrared heaters work by emitting radiant heat, which warms objects and people directly rather than heating the air. This makes them highly energy-efficient and effective in uninsulated garages, as the heat isn’t easily lost to drafts.

Infrared heaters are quiet, low-maintenance, and provide consistent warmth. However, they are typically more expensive upfront and have limited range, meaning multiple units might be needed for larger spaces.

IR heaters also lack the ability to quickly warm up a room, as the heating process is more gradual.

Kerosene Garage Heaters

Kerosene heaters are another portable option, ideal for garages without access to electricity or gas lines. They deliver high heat output and work well in extremely cold conditions. Kerosene is relatively inexpensive and easy to store for long-term use.

However, like propane heaters, they require ventilation to prevent carbon monoxide buildup. The strong odor of burning kerosene can also be unpleasant, and regular maintenance is necessary to ensure safe operation.

How To Choose The Best Overall Garage Heater For My Garage?

We think a high-quality heater should cater to your garage’s size, energy efficiency needs, and safety requirements. Here are seven essential features that define the best overall garage heater:

Adequate Heating Capacity (BTU Output)

The best garage heater should deliver sufficient heating power for your specific space. Heating capacity is measured in British Thermal Units (BTUs), with higher BTUs providing more heat.

For smaller garages, a heater with 5,000–10,000 BTUs may suffice, whereas larger garages may require 30,000 BTUs or more.

Garage Size(sq.ft)	Power in Watts	Power in BTUs
100	1,000	3,410
150 (1 car)	1,500	5,115
300 (1 car)	3,000	10,230
400 (1.5-2 cars)	4,000	13,640
500 (2-2.5 cars)	5,000	17,050
600 (2.5-3 cars)	6,000	20,460
800 (3-4 cars)	8,000	27,280
1000 (4+ cars)	10,000	34,100
1500	15,000	51,150
2000	20,000	68,200

A heater with adjustable settings is ideal, as it allows you to customize the output to your needs and conserve energy when full power isn’t necessary.

Energy Efficiency

Energy efficiency is crucial for minimizing operational costs and environmental impact. Look for heaters with features like programmable thermostats, energy-saving modes, or timers that allow precise control of heating periods.

Infrared heaters and models with high Energy Star ratings are particularly efficient, as they focus heat where it’s needed rather than warming the entire space.

Safety Features

Safety is non-negotiable when selecting a garage heater. Top models include essential safety features like overheat protection, tip-over shutoff mechanisms, and built-in carbon monoxide detectors for fuel-based heaters.

Proper safety certifications (e.g., UL or CSA) are also important indicators of a reliable product.

Durability and Build Quality

Garages often experience temperature fluctuations, dust, and rough handling, so the best garage heater must be robustly built. Models with sturdy metal housing, corrosion-resistant materials, and sealed motor compartments are better suited for such environments.

Durability ensures the heater remains operational for years without frequent repairs or replacements.

Versatility in Installation

A versatile heater can adapt to different garage layouts and user preferences. Options for wall-mounted, ceiling-mounted, or portable designs make it easier to optimize space and heat distribution.

Portable heaters are ideal for flexibility, while mounted units are better for permanent setups in larger garages.

Quiet Operation

A noisy heater can disrupt work, hobbies, or relaxation in your garage. The best heaters operate quietly, ensuring minimal distractions.

 Infrared and oil-filled radiators are excellent for maintaining low noise levels, while some electric heaters use advanced fan technology to reduce sound.

Ease of Use and Maintenance

Convenient operation and minimal upkeep enhance the overall user experience. Look for heaters with user-friendly controls, such as digital displays, remote controls, or smart home integration.

Easy maintenance features, like removable filters or accessible components, also ensure the heater runs efficiently without requiring professional servicing frequently.

How To Use A Garage Heater Safely?

Whether you’re working in the garage or using it for storage, a safe and well-maintained heater ensures warmth without compromising safety. Here are important tips to follow:

Choose the Right Heater for Your Garage

The first step in safe usage is selecting a heater appropriate for your garage size and fuel availability. Electric heaters are generally safer for enclosed spaces, while propane or natural gas heaters require proper ventilation to avoid carbon monoxide buildup.

If your garage is small, avoid overpowered heaters that may overheat the area.

Install the Heater Correctly

Follow the manufacturer’s instructions for installation. Fixed heaters, such as natural gas or electric wall-mounted units, often require professional installation to ensure proper placement and secure mounting.

Portable heaters should be positioned on a flat, stable surface away from flammable materials like:

• paper,
• gasoline, or
• wooden structures. 

Avoid placing heaters near doorways or areas prone to drafts, as this can disrupt heat distribution.

Ensure Proper Ventilation

For fuel-based heaters, such as propane, kerosene, or natural gas models, proper ventilation is critical. These heaters produce carbon monoxide, which is odorless and dangerous if allowed to accumulate.

Open a window or door slightly or use a ventilation system to allow fresh air to circulate. Carbon monoxide detectors should be installed and tested regularly to alert you of unsafe gas levels.

Keep the Area Around the Heater Clear

Maintain a safe distance between the heater and combustible items such as cardboard, fabric, or flammable liquids. Most manufacturers recommend keeping a clearance of at least 3 feet on all sides of the heater.

Avoid using the heater in spaces cluttered with potentially flammable items, as this increases the risk of fire.

Use Safe Power Sources

For electric heaters, plug them directly into a wall outlet instead of using extension cords, which can overheat and cause fires.

Ensure the outlet can handle the heater’s wattage, and avoid overloading circuits by running multiple high-wattage devices simultaneously.

Monitor the Heater During Use

Never leave a garage heater unattended, especially fuel-based or high-powered models.

While modern heaters come with safety features like overheat protection and automatic shutoff, being present allows you to respond quickly to any issues.

If you need to step away, turn the heater off first.

Perform Regular Maintenance

Routine maintenance helps prevent malfunctions that could lead to unsafe conditions. Clean filters, inspect fuel lines for leaks, and ensure fans or motors are functioning properly.

Follow the manufacturer’s maintenance schedule, and replace worn parts as needed. For fuel-based heaters, only use the recommended fuel type to avoid damaging the unit.
