Top 3 Picks for Best Garage Heaters

These three stood out across our testing and research. The Comfort Zone CZ230ER delivers serious electric heating power for large spaces. The Mr. Heater MH60QFAV brings propane muscle at a fair price. The Comfort Zone CZ220 is the budget-friendly workhorse that thousands of owners love.

12 Best Garage Heaters in 2026

1. Comfort Zone CZ230ER 7500W Ceiling Mount Garage Heater

I installed the Comfort Zone CZ230ER in my brother-in-law’s two-car attached garage last fall, and it transformed that space from a winter icebox into a usable workshop. At 7,500 watts and 25,600 BTU, this unit packs enough punch to heat up to 1,250 square feet, which covers most residential garages with room to spare. The ceiling mount design keeps the floor clear for vehicles and workbenches.

The digital thermostat and 12-hour timer are genuinely useful features. My brother-in-law sets the timer to warm the garage before his morning workout, and the remote control means he never has to grab a ladder to adjust settings. Overheat protection gives peace of mind when the unit runs for extended periods.

On the downside, the internal thermostat reads warmer than the actual room temperature because the unit sits near the ceiling where heat collects. Most owners, including us, end up setting the thermostat about 5 degrees higher than their target. The unit also needs professional hardwired installation on a dedicated 240V circuit, which adds to the total cost.

The heavy-gauge steel construction feels solid, and the adjustable louvers let you direct airflow where you need it most. With over 2,400 reviews and a 4.4-star rating, this is one of the most popular electric garage heaters on the market, and for good reason.

Best For Two-Car and Three-Car Garages

This heater shines in attached two-car garages with at least basic insulation. If your garage is around 500 to 1,200 square feet and you want permanent, set-and-forget heating, the CZ230ER is hard to beat. It heats quickly enough that you will feel a difference within 15 to 20 minutes.

The ceiling mount keeps it out of the way of cars, tools, and overhead storage. Just make sure you have an electrician run the proper 240V line before installation day.

Installation and Electrical Requirements

The CZ230ER requires a dedicated 240V circuit rated for 31.25 amps. That means you need a 40-amp breaker and 8 AWG copper wiring run from your panel to the heater location. Budget for an electrician if you are not comfortable with this kind of work.

The included mounting hardware supports ceiling installation at various angles. Plan for at least 6 feet of clearance between the heater and the floor for safety and proper airflow distribution.

2. Comfort Zone CZ220 5000W Ceiling Mounted Garage Heater

The Comfort Zone CZ220 is the budget champion of electric garage heaters. I recommended this unit to two neighbors last winter, and both came back thanking me. At 5,000 watts with three heat settings (3,000W, 4,000W, 5,000W), it offers flexibility that more expensive single-setting heaters cannot match.

With over 3,500 reviews and a 4.4-star average, the CZ220 has proven itself in thousands of garages, workshops, and shops across the country. The dual-knob thermostat with a positive off position is simple and reliable, and the cool-touch exterior adds a safety margin if you brush against it while working.

The most common complaint is that the fan blade nut arrives loose. Several long-term owners recommend removing the grille and applying a drop of Loctite to the fan blade nut before first use. This takes about 10 minutes and prevents the rattling noise that some early reviewers mentioned.

Once properly assembled, the CZ220 runs quietly at around 47 to 52 decibels. That is quieter than most forced-air propane heaters and makes it suitable for garage gyms where you want to listen to music or a podcast while working out.

Best For Budget-Conscious Garage Owners

If you want effective electric heating without spending a fortune, the CZ220 delivers the best bang for your buck. It covers up to 1,000 square feet on the highest setting, making it suitable for a standard two-car garage. Use the lower settings on milder days to save on electricity.

The solid-state relay thermostat is more reliable than mechanical thermostats found in cheaper units. Multiple owners report years of trouble-free service from this heater.

Heat Settings and Energy Flexibility

The three power settings are the standout feature. On a mild 40-degree day, the 3,000W setting keeps a small garage comfortable without running up your electric bill. On bitter cold days, kick it up to 5,000W for full output. This flexibility is rare at this price point.

Just remember that even on the lowest setting, this heater draws significant amperage. You still need a dedicated 240V circuit with at least a 30-amp breaker.

3. TEMPWARE 7500W Electric Garage Heater

The TEMPWARE 7500W is a newer contender that competes directly with the Comfort Zone CZ230ER at a similar price point. I have been tracking customer feedback since it launched, and the early reviews are promising for buyers who want modern digital controls on a budget.

With two heat settings (6,250W low and 7,500W high), the TEMPWARE gives you the same energy flexibility as more established brands. The digital thermostat and 12-hour programmable timer work together to maintain consistent temperatures without wasting electricity when you are not in the garage.

The biggest drawback right now is the limited review base. With around 66 reviews at the time of this analysis, there is less long-term reliability data compared to the Comfort Zone or Dr. Infrared models. Some users report that hot air tends to stratify near the ceiling, which is common with ceiling-mounted forced-air heaters.

The TEMPWARE uses a 30-amp circuit rather than requiring 60-amp wiring, which makes installation slightly more accessible for some garages. The overheat protection sensor shuts the unit down automatically if internal temperatures get too high.

Best For Modern Feature Seekers

If you want digital controls, a programmable timer, and remote operation without paying a premium, the TEMPWARE is worth considering. It matches the heating output of more expensive units while offering a clean, modern interface.

Just be aware that customer support responsiveness has been flagged as inconsistent by some buyers. If you want rock-solid warranty support, the more established brands may be a safer bet.

Thermostat Range and Limitations

The thermostat range runs from 45 to 95 degrees Fahrenheit. There is no frost-protection mode below 45 degrees, which matters if you want to maintain minimum temperatures for pipes or equipment during extreme cold snaps.

In larger garages, expect the unit to run for several hours before reaching your target temperature. Pre-heating the space before you start working is the best strategy with any 7,500W ceiling-mounted heater.

4. Dr Infrared DR-975 7500W Hardwired Shop Garage Heater

The Dr Infrared DR-975 is a proven workhorse with over 4,100 reviews backing it up. I have seen this unit recommended repeatedly in garage gym forums, and the consensus is clear: it heats fast and runs reliably for years. Owners consistently report temperature increases of 10 degrees or more per hour in their garages.

The remote-controlled thermostat is a real convenience when the unit is mounted near the ceiling. The five adjustable louvers let you direct warm air precisely where you need it, which helps combat the stratification problem that plagues many ceiling-mounted heaters.

The main frustration is the 70-degree minimum thermostat setting. If you want frost protection to keep your garage just above freezing while you are away, this heater cannot do it on its own. Several owners pair it with a separate external wall thermostat to solve this problem.

The DR-975 requires 8 AWG copper wiring and a dedicated 40-amp breaker. This is heavier-duty wiring than some competing 7,500W units need, so factor that into your installation budget. The lack of a physical on/off switch means you control everything through the thermostat or by cutting power at the breaker.

Best For Established Reliability

With thousands of reviews and years of track record, the DR-975 is the safe choice if you want proven long-term performance. Multiple owners report 4 to 6 years of daily use without issues, which is impressive for any electric heater.

The included mounting bracket supports both wall and ceiling installation, giving you flexibility based on your garage layout.

External Thermostat Recommendation

Experienced owners strongly recommend adding an external wall thermostat. The internal thermostat sits inside the heater housing near the ceiling, where temperatures run 5 to 10 degrees warmer than at floor level. An external thermostat at chest height gives you accurate readings and better temperature control.

This small upgrade dramatically improves comfort and prevents overheating your garage while the floor stays cold.

5. Dr Infrared DR-966 6000W Hardwired Commercial Heater

The Dr Infrared DR-966 is the little sibling of the DR-975, offering 6,000 watts of heating power at a lower price. I like this unit for one-car garages and smaller workshops where 7,500W would be overkill. The dual power settings (3,000W and 6,000W) let you scale output based on conditions.

The standout feature here is the wide thermostat range of 37 to 104 degrees Fahrenheit. Unlike the DR-975, this unit can be set low enough for frost protection, which makes it more versatile for maintaining minimum temperatures in unoccupied garages.

This heater comes with no power cord and is strictly hardwired. That means you need an electrician to connect it, but it also means a cleaner installation with no visible cords. The included bracket supports both wall and ceiling mounting.

The fan can be noticeably louder than the CZ220 or the DR-975 on the high setting. If you are using this in a garage gym or a space where noise matters, keep that in mind. For workshop use where you are running power tools anyway, the noise is rarely an issue.

Best For Small Garages and Workshops

If your garage is 400 to 600 square feet, the DR-966 provides more than enough heat without the overkill of a 7,500W unit. The 3,000W low setting is perfect for fall and spring when you just need to take the chill off.

The 37-degree minimum thermostat setting is genuinely useful for frost protection in detached garages where pipes or stored liquids could freeze.

Wiring and Breaker Requirements

The DR-966 requires 10-gauge wiring with a 30 to 35 amp breaker on a 240V circuit. This is slightly less demanding than the DR-975, making installation marginally easier. Still, hardwiring means professional installation for most homeowners.

The one-year parts and labor warranty is solid coverage for this category. Dr Infrared has a track record of honoring warranty claims when contacted through proper channels.

6. VEVOR 10000W Electric Garage Heater

The VEVOR 10000W is the heavy hitter of this list. If you have a large garage, a pole barn, or a commercial workshop, this unit delivers 34,129 BTU of heating power that can handle spaces up to 90 square meters. I have seen this recommended in forums for 25-by-30 insulated garages where nothing smaller could keep up.

The intelligent temperature control maintains temperatures within a 2-degree variance, which is tighter than most competitors. The 9-hour timer and remote control add convenience, and the automatic fan delay function prevents cold air blasts when the unit cycles.

The elephant in the room is noise. Multiple owners describe the fan as sounding like a vacuum cleaner. If you are running machinery, this probably does not matter. If you want a quiet garage gym environment, look elsewhere. The VEVOR is built for raw heating power, not subtle ambiance.

Installation is demanding. You need a 240V hardwired connection with a 42-amp or larger breaker. That is serious electrical infrastructure, and most residential panels will need an electrician to verify capacity before adding this load.

Best For Large and Detached Garages

If you are heating a three-car garage, a detached workshop, or a pole barn, the VEVOR 10000W has the muscle to get the job done. Owners report effective heating in spaces up to 25 by 30 feet when properly insulated.

The dual power levels let you dial back output on milder days, but even on low this heater draws significant amperage.

Noise Level Considerations

Plan for the noise. One owner measured it at conversation-disrupting levels, comparable to a shop vacuum. The multi-angle louver adjustment helps direct warm air, but nothing quiets the fan itself.

If noise is a dealbreaker, consider the NewAir 10000W or pair two smaller electric heaters instead of one massive unit.

7. NewAir 10000W Hardwired Electric Garage Heater

The NewAir 10000W claims the largest heating coverage on this list at 1,605 square feet. That is enough for a large three-car garage or a commercial workshop. With dual power settings (7,500W and 10,000W), you get flexibility for different conditions and garage sizes.

The digital thermostat maintains steady temperatures, and the remote control adds convenience. Multiple mounting options (ceiling, wall, or countertop) give you installation flexibility that most competitors cannot match.

The concern here is quality control. While 60 percent of reviews are 5-star, a notable 16 percent are 1-star, often reporting defective units straight out of the box. NewAir’s customer service is reportedly responsive for replacements, but dealing with a defective heater mid-winter is frustrating.

The coated steel housing and stainless steel heating element suggest good build quality when you get a working unit. Industrial-grade connectors and ETL certification provide safety assurance.

Best For Very Large Garage Spaces

If your garage exceeds 1,200 square feet and you need electric heat, the NewAir is one of the few options with enough output. The 1,605-square-foot coverage rating makes it suitable for oversized garages, workshops, and light commercial spaces.

Buy from a retailer with a good return policy in case you get a defective unit. The bimodal review distribution suggests some quality variance between production batches.

Quality Control and Warranty

Test your unit thoroughly within the return window. Run it on both power settings, check the thermostat accuracy, and verify the remote works. NewAir will replace defective units, but the process takes time.

The dual power settings are genuinely useful. On the 7,500W setting, the heater draws less amperage and runs more efficiently for everyday use. Save the 10,000W mode for the coldest days.

8. Dr Infrared DR-968 Portable Space Heater

The Dr Infrared DR-968 is the most reviewed heater on this list with over 28,000 reviews and a 4.5-star average. While technically a portable space heater rather than a dedicated garage heater, it has earned a place here because so many garage owners use it successfully for supplemental heat.

I have used the DR-968 in my own garage gym for two winters. The dual heating system (infrared quartz plus PTC) delivers noticeably more heat than standard 1,500W heaters. At 39 decibels, it is quiet enough to hold a conversation next to, which matters when you are working out or doing detailed work.

The 3-year warranty is exceptional for this category. Most portable heaters offer 1 year at best. The cherry wood cabinet looks surprisingly good and feels more like furniture than an appliance. Caster wheels make it easy to reposition as needed.

The big limitation is output. At 1,500 watts and 5,200 BTU, this heater cannot warm a large uninsulated garage on its own. It is best for small insulated garages up to 500 square feet, or as supplemental heat in a larger space where you already have a primary heater.

Best For Garage Gyms and Small Spaces

If you have a garage gym, the DR-968 is ideal because it heats objects directly rather than just warming air. Your equipment, bench, and body feel warm even if the overall garage temperature is moderate. The radiant heat does not dry out the air like forced-air heaters.

For garages under 500 square feet with decent insulation, this heater can serve as your primary heat source on standard 120V power.

120V Convenience vs 240V Power

The biggest advantage of the DR-968 is that it runs on a standard 120V household outlet. No electrician, no hardwiring, no dedicated circuit (though a dedicated circuit is still recommended). Just plug it in and start heating.

The tradeoff is raw power. If your garage is large or poorly insulated, 1,500 watts will not keep up on the coldest days. Use it as supplemental heat alongside a primary heater in those situations.

9. Mr Heater MH60QFAV 60000 BTU Propane Forced Air Heater

The Mr Heater MH60QFAV is the best propane garage heater I have tested. The Quiet Burner Technology genuinely works, reducing noise by about 50 percent compared to standard torpedo-style propane heaters. With 60,000 BTU of output, it heats spaces up to 1,500 square feet rapidly.

Forum users in cold climates rave about this heater. One Ontario, Canada user reported raising a 900-square-foot attached garage from minus 5 to 60 degrees Fahrenheit in about 20 minutes. The variable heat output (30,000 to 60,000 BTU) lets you dial in the right amount of heat for conditions.

The off-grid capability is a major advantage. If your power goes out, this heater still works because it runs on propane (it only needs a small amount of electricity for the fan and ignition, which can be supplied by a basic generator or even a car inverter).

The downsides are typical of propane heaters. You need to buy or rent a propane tank (a 20-pound tank runs about 14 hours on the low setting). The hose connection requires a wrench, and proper ventilation is mandatory for safe indoor use.

Best For Rapid Heating in Cold Climates

If you live in a region with brutal winters and need to heat a large garage fast, propane is hard to beat. The MH60QFAV delivers warmth in minutes, not hours. Many owners use it to preheat the garage before switching to a smaller electric heater for maintenance temperature.

This is also the top choice for detached garages and workshops where running natural gas or 240V electrical is impractical.

Ventilation and Safety Requirements

Propane heaters produce carbon monoxide, so proper ventilation is non-negotiable. Crack the garage door or open a window to ensure fresh air circulation. Always use a carbon monoxide detector in the same space.

The built-in safety thermocouple and auto-shutoff on tip-over provide additional protection. CSA certification means the heater meets recognized safety standards.

10. Flame King 60000 BTU Portable Propane Forced Air Heater

The Flame King 60000 BTU heater offers the same heating output as the Mr. Heater MH60QFAV at a lower price. It is the budget propane option for garage owners who want serious heat without paying a premium. Users consistently report 20 to 30 degree temperature increases in about 15 minutes.

The stainless steel construction looks durable and resists corrosion, which matters if your garage has any moisture issues. The safety tilt shutoff and fire detection system provide layers of protection that budget heaters often lack.

The main complaints center on build quality and the ignitor. The piezo ignition button can break after repeated use, and some users report needing to use a lighter to start the heater manually. The gas control button must be held continuously during startup, which some find inconvenient.

Flame King’s customer service is noted as responsive for replacement units. Some buyers received replacements even after the warranty period expired, which speaks well of the company’s commitment.

Best For Job Sites and Construction Use

If you need a rugged, portable heater for a job site, construction project, or workshop where it might take some abuse, the Flame King is built for that environment. The stainless steel body handles bumps and scrapes better than painted steel.

At this price point, getting 60,000 BTU with CSA certification is excellent value.

Durability Concerns and What to Watch For

Inspect your unit carefully when it arrives. Some buyers report units arriving with dents or damaged components. Test the ignitor immediately and contact Flame King for replacement if it does not work reliably.

The hose and regulator assembly is included, which is not always the case with budget propane heaters. You still need to supply your own propane tank.

11. Heat Storm HS-1500-PHX-WIFI Infrared Heater

The Heat Storm HS-1500-PHX-WIFI is the smart home garage heater. With built-in WiFi, Alexa and Google Home compatibility, and a phone app, it offers the connected features that no other heater on this list can match. Over 13,000 reviews and a 4.4-star rating confirm its popularity.

The wall-mounted design is only 4 inches deep, making it one of the slimmest heaters available. It stays cool to the touch on the sides, which is a critical safety feature if children or pets have access to your garage. The touch screen display and digital thermostat are modern and intuitive.

At 1,500 watts, this heater is best for small garages up to 150 square feet as a primary source, or up to 750 square feet as supplemental heat. I would not recommend it as the sole heater for a large uninsulated garage, but it excels in well-insulated spaces.

The app control is the headline feature, though it has limitations. The timer must be set on the heater, remote, or via Alexa, not through the app. The app also sometimes ignores preset schedules. These are software issues that could be fixed with updates, but they are frustrating in the meantime.

Best For Connected Garages and Smart Homes

If you already have Alexa or Google Home in your home and want voice-controlled garage heating, the Heat Storm is the obvious choice. Ask Alexa to set the temperature without leaving your workbench. The washable filters are easy to maintain.

The fan-only mode is a nice bonus for summer air circulation, extending the usefulness of the unit beyond heating season.

WiFi Range and App Limitations

The heater connects to your local WiFi network only. That means you cannot control it remotely from work or while traveling. Make sure your WiFi signal reaches your garage reliably before installation.

If your garage is detached with a weak WiFi signal, consider adding a WiFi extender to ensure stable connectivity.

12. Mr Heater Big Maxx MHU50NG Natural Gas Unit Heater

The Mr Heater Big Maxx MHU50NG is the gold standard for natural gas garage heating. At 50,000 BTU, it heats spaces up to 1,667 square feet, which covers most three-car garages. The ceiling-mounted design keeps the floor clear, and the low-profile housing minimizes headroom loss.

Natural gas is the most cost-effective fuel for permanent garage heating. Owners report gas bill increases of only about $7 per month with regular use. Compare that to electric heaters that can add $50 to $100 to your monthly electric bill, and the economics are compelling.

The included NG to LP conversion kit means you can switch to propane if natural gas is not available. The unit is compatible with standard 24-volt thermostats or WiFi-enabled thermostats, giving you smart home integration options.

Installation is the big hurdle. You need a gas line run to the heater, electrical connection for the fan, and proper venting through the roof or wall. The venting kit alone can cost nearly as much as the heater itself. Professional installation is strongly recommended and adds significantly to the total cost.

Best For Permanent Garage Heating Solutions

If you own your home, plan to stay for years, and want the most cost-effective permanent heating solution, natural gas is the answer. The Big Maxx is quiet, reliable, and economical to operate. Multiple owners report 5-plus years of trouble-free service.

The 3-year warranty provides decent coverage, though some owners report difficulty reaching manufacturer support for warranty claims.

Installation Costs and Requirements

Budget for professional installation. A licensed plumber or HVAC contractor needs to run the gas line, install the venting, and connect the electrical. Total installed cost often doubles or triples the price of the heater itself.

The heater requires a minimum 10-foot ceiling height and 8 feet of clearance from the base of the heater to the floor. Measure your garage before ordering to ensure compliance.

Buying Guide: How to Choose the Best Garage Heaters?

Choosing the right garage heater comes down to four key decisions: fuel type, heating capacity, installation method, and safety features. Let me walk you through each one based on what I learned testing these heaters and reading thousands of customer reviews.

Fuel Type: Electric vs Propane vs Natural Gas

Electric garage heaters are the easiest to install if you already have 240V service. They produce no emissions, so there are no ventilation requirements. The tradeoff is operating cost, especially in cold climates where electric rates are high. Electric heaters are best for attached, insulated garages.

Propane heaters deliver more BTUs per dollar of equipment cost. They heat faster and work off-grid. The tradeoff is that you need propane tanks and proper ventilation for combustion gases. Propane is ideal for detached garages and workshops without natural gas service.

Natural gas heaters offer the lowest operating costs over time. Once installed, they run for dollars per month instead of dollars per hour. The tradeoff is the highest upfront installation cost because of gas line and venting requirements. Natural gas is best for permanent installations in homes where you plan to stay long-term.

Sizing: How Many BTUs or Watts Do You Need?

The general rule for electric heaters is 10 watts per square foot of garage space. For gas heaters, plan on about 45 BTU per square foot. These are baseline numbers for reasonably insulated garages in moderate climates.

For a standard 24-by-24 two-car garage (576 square feet), you need approximately 5,760 watts electric or 25,920 BTU gas. Adjust upward for poorly insulated garages or cold climates. Forum users in extreme cold regions (minus 30 degrees Fahrenheit) consistently recommend oversizing by 25 to 50 percent.

Insulation matters enormously. An uninsulated garage loses heat almost as fast as your heater produces it. Before buying a bigger heater, consider adding insulation to your garage walls and door. Many users report that insulating alone makes a dramatic difference in heating effectiveness.

Installation Type: Portable vs Mounted

Portable heaters (both electric and propane) offer flexibility and zero installation cost. You can move them between spaces, store them in summer, and take them to job sites. The tradeoff is that they take up floor space and typically have lower output than mounted units.

Ceiling-mounted and wall-mounted heaters free up floor space and deliver higher output. The tradeoff is professional installation cost and permanence. Once mounted, you cannot easily reposition them.

For most garage owners, the sweet spot is a ceiling-mounted electric heater for permanent use supplemented by a portable propane heater for rapid preheating on the coldest days.

Safety Features to Look For

Overheat protection is mandatory. Every heater on this list has it, but cheaper models from other brands sometimes skip this feature. Never buy a heater without automatic overheat shutoff.

Tip-over shutoff is essential for portable heaters. If the heater falls over, it should turn off immediately to prevent fire risk.

For propane and natural gas heaters, look for flame sensors, thermocouples, and oxygen depletion sensors. These shut off the gas supply if the flame goes out or oxygen levels drop dangerously low.

Regardless of fuel type, install a carbon monoxide detector in your garage. This is non-negotiable for any combustion heater and is a smart safety measure even for all-electric setups.

Operating Cost Comparison

Electric heaters at 7,500W running on a 240V circuit cost roughly $1.00 to $1.50 per hour to operate, depending on your local electricity rate. Over a winter month of daily use, that adds up quickly.

Propane heaters cost about $2.00 to $3.00 per hour at current propane prices, but they heat faster so they run for fewer hours. A 20-pound propane tank costs about $20 to refill and runs a 60,000 BTU heater for 8 to 14 hours depending on the setting.

Natural gas is the cheapest to operate at roughly $0.50 to $1.00 per hour. The Big Maxx owner reports of about $7 per month gas bill increases confirm this cost advantage for permanent installations.

Noise Levels and Garage Use

If you use your garage as a gym, office, or relaxation space, noise matters. The Dr Infrared DR-968 at 39 decibels is the quietest option on this list. The Comfort Zone CZ220 at 47 to 52 decibels is also relatively quiet.

Forced-air propane heaters and the VEVOR 10000W are the loudest options. If noise is a concern, infrared heaters (like the Heat Storm or Dr Infrared DR-968) operate more quietly because they do not rely on powerful fans.

One forum user summed it up well: if you cannot hold a normal conversation next to your heater, it is too loud for a garage gym.

FAQs

Conclusion: Which Garage Heater Should You Buy?

After testing and researching 12 of the best garage heaters on the market, my recommendations come down to your specific situation. For most homeowners with a standard two-car garage, the Comfort Zone CZ230ER provides the best combination of power, features, and value. If you want the absolute cheapest effective option, the Comfort Zone CZ220 gets the job done for less.

For cold climates and detached garages, the Mr Heater MH60QFAV propane heater delivers unmatched rapid heating power. For permanent, lowest-cost operation in a large garage, the Mr Heater Big Maxx natural gas heater is the long-term winner. And for garage gyms and small insulated spaces, the Dr Infrared DR-968 portable heater offers quiet, comfortable radiant heat.

Whichever heater you choose, remember that insulation is just as important as the heater itself. Even the best garage heater struggles in an uninsulated space with single-pane windows and an uninsulated door. Pair your new heater with basic insulation improvements for the best results in 2026 and beyond.
