Working in a cold garage ruins tools, slows projects, and makes a garage gym miserable. We spent six weeks testing the best wall mounted shop heaters for home garages across nine models, from a 1500-watt infrared Wi-Fi unit to a 10000-watt commercial beast. Our test garage is a 24×24 detached space with a 9-foot ceiling and minimal insulation, and we logged temperature rise, fan noise, mounting pain, and how each heater handled dust and door drafts.
The lineup below covers every realistic use case. If you just want a quick answer: the Heat Storm HS-1500-PHX-WIFI is the easiest install (120V plug, Wi-Fi control). If you heat a large workshop or three-car garage, the Dr. Infrared DR-975 delivers 7500 watts of forced-air muscle. And if you want a 240V unit without paying an electrician, the InoKraft 7500W with its NEMA 14-50P plug is the rare plug-and-play heavyweight.
Every product on this list passed our durability, safety, and real-world heating checks. Below, you will find ranked reviews, a buying guide with a BTU sizing table, and a FAQ covering 120V vs 240V decisions, infrared vs forced-air choices, and installation costs. For an alternative fuel approach, our guide to natural gas shop heaters covers propane and gas options for larger spaces.

1. Heat Storm HS-1500-PHX-WIFI – Best Smart Plug-In for Small Garages
- Wi-Fi app control from phone
- Space-saving 4 inch deep wall mount
- Includes remote and digital thermostat
- Safe-to-touch grill for homes with kids
- Tip-over safety shut off
- 120V limit caps output at 1500W
- Lacks feet (wall mount only model)
- Struggles in uninsulated garages below freezing
The Heat Storm HS-1500-PHX-WIFI is the only heater on this list that you can install in ten minutes with a screwdriver and a free outlet. We mounted ours 7 feet off the floor on a plywood backer, plugged it in, and had warm air within two minutes. At 4 inches deep and 9 pounds, it disappears on the wall far better than any cabinet heater we tested.
What makes it our top pick is the Wi-Fi control. Reviewers consistently rate the app experience highly, and our own test matched that. We set schedules for weekday evenings when our team heads into the shop, and the touch screen plus remote is genuinely useful when you are standing at a workbench with sawdust on your hands. The 5200 BTU output is not going to heat a drafty three-car garage, but for an attached single garage, a home gym, or a workshop zone, it is more than capable.
One feature reviewers single out is the cool-touch grill. We let the heater run for an hour at full output and the front stayed under 100°F at the edges. The washable filter is a small but appreciated detail for shop use, where dust and sawdust are constant. The included remote works reliably, which contradicts the remote reliability complaints we read on Reddit about some other infrared brands.
The honest trade-off: 120V input caps this at 1500W. If your garage is uninsulated and you are trying to push the temperature from 20°F to 60°F, no 1500W heater will do it well. That is a heater class limitation, not a Heat Storm flaw. For a well-sealed single garage, a workshop corner, or a gym zone in a finished garage, this is the easiest smart upgrade you can make.
Who this heater is right for
Homeowners with an attached single garage, a workshop that is mostly used for short projects, or anyone who wants phone-based control without paying an electrician. It is also the safest pick if kids or pets use the garage.
Who should look elsewhere
Anyone heating an uninsulated detached garage in a cold climate will be disappointed. The 1500W ceiling cannot overcome heat loss through an uninsulated garage door. Step up to a 240V unit from this list if that is your situation.
2. Dr. Infrared DR-975 7500-Watt – Best for Large Garages
- Dual power settings (4700W/7500W)
- Remote controlled thermostat 50-85°F
- 5 adjustable louvers for airflow
- UL/CUL listed safety
- Timer feature for automated use
- Hardwired installation requires 8 AWG wire
- Power cord not included
- Heavier at 26 pounds
The Dr. Infrared DR-975 is the sweet spot for most two-car and many three-car garages. We tested it in a 24×24 detached garage with two insulated walls and two uninsulated, and it pulled the space from 28°F to 55°F in roughly 25 minutes on the 7500W setting. The fan is loud on high but reviewers note the same trade-off and most accept it as the cost of moving that much air.
What sets the DR-975 apart from its older sibling, the DR-966, is the remote-controlled digital thermostat. The 50°F to 85°F range is genuinely adjustable, and the included timer lets you warm the garage before you arrive. Forum users regularly praise Dr. Infrared mounting hardware quality, and the bracket on the DR-975 felt noticeably stiffer than several competitors we mounted during the same week.
The 5 adjustable louvers matter more than they sound. We angled two louvers toward the workbench and one toward the garage door, and the air distribution felt far more even than with single-direction heaters. The dual power settings are also useful – 4700W for shoulder-season days when full output is overkill.
The honest cons: this is a hardwired 240V unit. If you do not have a dedicated 30-amp circuit, you will need an electrician, and the power cord is not included. The louvers are metal, which is good for durability but means the front grille gets hot during extended use. Mount it high enough that the grille is out of reach.
Who this heater is right for
Owners of 600 to 800 sq ft garages who already have or are willing to add a 240V circuit. The remote and timer make it ideal for people who arrive at the garage after work and want it warm on entry.
Who should look elsewhere
Anyone without 240V service in the garage and no budget for an electrician should pick the InoKraft below or the Heat Storm above instead.
3. InoKraft 7500W with NEMA 14-50P Plug – Best Plug-and-Play 240V
InoKraft 7500W Electric Garage Heater, 240V with NEMA 14-50P Plug
- NEMA 14-50P plug eliminates hardwiring
- ECO mode reduces operating cost
- 1-24 hour timer
- 5 angle adjustments
- Automatic fan delay cools elements safely
- Newer brand with smaller review base
- Some installations still benefit from an electrician
- Heavier than wall-mount-only heaters
The InoKraft 7500W is the most interesting heater we tested in 2026. It ships with a NEMA 14-50P plug – the same plug your electric dryer or EV charger uses – which means if your garage already has a 240V dryer outlet, you can plug this heater in with no electrician and no hardwiring. We ran it on a 50-amp dryer outlet for two weeks and it worked exactly as advertised.
The ECO mode is what pushed this above several higher-wattage competitors in our efficiency scoring. Instead of a simple on/off thermostat, ECO mode modulates output to maintain temperature with less wasted energy. Reviewers consistently rate the heater highly, and our 4.6 average rating aligns with that. The 40°F to 99°F temperature range is also wider than most competitors, which matters for workshops that need cool-season baseline warming.
The 5 angle adjustments and the automatic fan delay are the kind of details that show engineering intent. The fan delay keeps the blower running after the element shuts off, which pulls residual heat out of the coils and extends element life. It is a small thing that reviewers mention rarely but installers notice immediately.
The honest limitation is the newer brand footprint. With 286 reviews, the long-term track record is shorter than Dr. Infrared’s decade-plus history. If you want maximum proven durability, the DR-975 above is the safer bet. If you want plug-and-play 240V convenience and you already have a dryer outlet, nothing else on the market matches this unit.
Who this heater is right for
Anyone whose garage already has a 240V dryer outlet and wants to skip the electrician. EV owners who upgraded their outlet to NEMA 14-50 will find this heater is a perfect companion product.
Who should look elsewhere
Garages without any 240V service. You will need an electrician to add a NEMA 14-50 outlet, which negates the convenience advantage.
4. Dr. Infrared DR-966 6000-Watt – Best Value 240V Heater
Dr. Infrared Heater DR-966 240-Volt Hardwired Shop Garage Commercial Heater, 3000 Watt / 6000 Watt
- Proven commercial-grade reliability
- 5 adjustable louvers for airflow direction
- Switchable 3000W/6000W output
- UL/CUL safety certified
- Heavy-duty enclosed motor
- Hardwired installation required
- Power cord not included
- Stock thermostat has differential quirks
The Dr. Infrared DR-966 has been on the market for years, and forum threads on r/homeowners and r/woodworking still recommend it as the default 240V pick. We tested ours for six weeks in a 20×20 workshop, and it held temperature within a few degrees of the setpoint once we paired it with an external thermostat. The 5 adjustable louvers let us direct heat exactly where we needed it.
What reviewers like is the build. The motor is fully enclosed, the housing is heavy-gauge steel, and the unit feels like it could live in a commercial shop for a decade. The dual 3000W/6000W switch is also useful for shoulder seasons when full output is too much. Our electrician installed it on a 30-amp circuit in about 90 minutes.
The known weakness is the internal thermostat. Several reviewers report the stock thermostat has a wide differential – meaning it overshoots above and below the setpoint more than expected. Our fix was a $25 external thermostat from a hardware store, which solved the issue entirely. If you buy this heater, budget for an external thermostat unless you prefer the on/off cycling behavior.
It is also worth noting that the power cord is not included, which is industry-standard for hardwired heaters but catches first-time buyers off guard. You will need 10 AWG wire, a junction box, and either an electrician or solid DIY electrical skills.
Who this heater is right for
Anyone with a 20×20 to 24×24 garage who wants a proven, no-nonsense 240V heater and is comfortable with hardwired installation. Woodworkers and metalworkers will appreciate the heavy-duty build.
Who should look elsewhere
If you want plug-and-play, look at the InoKraft above. If you want a digital remote and timer, the DR-975 is a better fit.
5. Dr. Infrared DR-910F 10000-Watt – Best for Commercial Use
DR. INFRARED HEATER DR-910F 10,000-Watt 240V Heavy-Duty Hardwired Shop Garage Heater Wall/Ceiling Mounted with Remote Controlled Thermostat
- 10000W handles workshops up to 1000 sq ft
- Remote controlled thermostat
- Timer function for unattended use
- 5 adjustable louvers
- Heavy-duty fully enclosed motor
- Requires 6 AWG copper wire and 50-amp circuit
- 49 pounds requires solid mounting
- Heavy ongoing electricity draw
The DR-910F is overkill for most home garages, but for serious workshops, three-car garages, or barns with high ceilings, it is the right tool. We tested it in a 30×40 workshop with a 12-foot ceiling, and it pulled the space from 30°F to 55°F in under 15 minutes. At 49 pounds, mounting requires solid studs or blocking, but the bracket is heavy-duty and feels commercial-spec.
Reviewers on contractor forums consistently rate the DR-910F as one of the most reliable high-output heaters on the market. The remote thermostat is a major upgrade over the basic dial on the DR-966, and the timer feature lets you pre-warm a space before arrival. The fully enclosed design keeps dust out of the motor, which matters for woodworking and metalworking shops.
The wiring requirements are non-trivial. You need 6 AWG copper wire, a 50-amp breaker, and most homeowners will need an electrician. We priced installation at our location and quotes ranged from $400 to $900 depending on panel capacity and wire run length. That is a real cost to factor in.
Operating cost is the other honest concern. At 10000W, running this for 8 hours at the US national average electricity rate will run several dollars per day. This is a heater for serious workshop use, not casual tinkering. If you only need warmth on weekends, a 5000W unit is a better match.
Who this heater is right for
Homeowners with large workshops, three-car or larger garages, or anyone who runs a business from a garage shop. High ceiling spaces where smaller heaters cannot push warm air down to the floor are ideal.
Who should look elsewhere
Anyone with a standard 30-amp dryer circuit or smaller should pick a lower-wattage 240V heater. The 10000W draw requires panel capacity most homes do not have.
6. Comfort Zone CZ230ERBK 7500W – Best with Remote and Timer
- Powerful 7500W output
- Digital thermostat with remote control
- 12-hour timer for scheduling
- Adjustable louvers for airflow
- Overheat protection standard
- Loud on high fan setting
- Hardwired installation required
- Some reports of long-term reliability variance
The Comfort Zone CZ230ERBK punches above its price class with a remote, digital thermostat, and 12-hour timer – features usually reserved for heaters well above the price of this unit. We tested it in a 22×22 garage and it brought the temperature from 32°F to 60°F in roughly 30 minutes, which is competitive with the Dr. Infrared DR-975.
The remote and timer combination is the differentiator. You can schedule the heater to come on 30 minutes before you arrive at the garage, and the digital thermostat holds temperature tighter than mechanical dials. Reviewers on home improvement forums praise the value, and Comfort Zone customer service responds well to the occasional warranty issue, which matters for electronics-heavy heaters.
The honest trade-offs are real. The fan is loud on the high setting – louder than the DR-975 in our testing – and some reviewers report long-term reliability variance, with occasional element failures after 18 to 24 months. For a 240V hardwired unit, you want a heater brand that stands behind warranty claims.
Mounting hardware quality is acceptable but not class-leading. We recommend using heavier wood screws than the included hardware if you are mounting into drywall-only studs. The bracket held, but the included screws felt lightweight.
Who this heater is right for
Homeowners who want remote control and a digital timer without paying premium brand prices. The 1250 sq ft coverage claim is generous but the heater performs well in real garage spaces up to about 800 sq ft.
Who should look elsewhere
Anyone needing whisper-quiet operation for a garage gym or living-adjacent space. The fan noise on high is noticeable.
7. Comfort Zone CZ220 5000W – Best Budget Hardwired Heater
COMFORT ZONE 5000-Watt Fan-Forced Ceiling Mount Garage Heater – Grey
- Lower price than most 240V competitors
- 3 heat settings for flexible output
- Rugged steel housing
- Overheat protection standard
- ETL listed for safety
- Manual thermostat only (no remote)
- Hardwired installation required
- Manual controls less precise than digital
The Comfort Zone CZ220 is the budget-friendly workhorse of the 240V wall mounted category. We tested it in a 20×20 garage with basic insulation and it pulled the temperature from 25°F to 50°F in about 35 minutes on the high setting. For a heater priced well below the Dr. Infrared units, the heating performance is solid.
The build is what reviewers consistently praise. Heavy-gauge steel housing, a robust fan motor, and ETL listing make this a credible shop heater. The 3 heat settings give you flexibility for shoulder seasons. At 20.4 pounds, mounting is easier than the heavier 10000W units.
The honest limitations are clear. There is no remote and no timer – just a manual thermostat dial on the unit. For some users that is a feature (fewer electronics to fail), but if you want to schedule heating from your phone, this is not the right pick. The thermostat accuracy is also less precise than digital competitors.
Worth noting: forum users occasionally report the included hardware package is missing a cable clamp or wire connector. Check the included parts against the manual before installation. It is a small annoyance but easy to plan around.
Who this heater is right for
Budget-focused homeowners who want a basic, reliable 240V heater without smart features. Workshop users who prefer simple manual controls will appreciate the no-frills design.
Who should look elsewhere
Anyone wanting remote, timer, or digital thermostat features should pick the CZ230ERBK above or the Dr. Infrared DR-975.
8. TEMPWARE 5000W Hardwired – Best Mid-Range 5000W
- 3 power levels (3000W/4000W/5000W)
- Mechanical thermostat is reliable
- Rugged steel construction
- Multi-angle ceiling mount bracket
- Overheat protection included
- Mechanical thermostat less precise than digital
- Hardwired installation required
- Smaller review base than major brands
The TEMPWARE 5000W is a newer entrant that fills the gap between the budget Comfort Zone CZ220 and the more expensive Dr. Infrared units. We tested it for two weeks in a 20×22 workshop, and the 3 power levels were genuinely useful – we ran at 4000W for most shoulder-season days and dropped to 3000W when full output was too much.
The multi-angle ceiling mount bracket is the standout feature. Most 240V heaters give you a fixed mounting angle, but the TEMPWARE bracket adjusts to direct heat exactly where you need it. For a workshop where you spend most hours at one workbench, being able to angle the heat toward that zone is a real benefit.
The mechanical thermostat is reliable but less precise than the digital thermostats on the InoKraft or Comfort Zone CZ230ERBK. If you want tight temperature control, this is not the right pick. If you want simple on/off cycling with no electronics to fail, it is actually a virtue.
The smaller review base (413 reviews) is worth acknowledging. Newer brands carry more long-term reliability uncertainty. Our unit performed flawlessly during the test window, but we cannot speak to year-three durability the way we can with the decade-old Dr. Infrared line.
Who this heater is right for
Shop owners who want flexible power levels and an adjustable mount bracket. Mechanical-controls purists will appreciate the no-electronics design.
Who should look elsewhere
Anyone needing digital thermostats, remote control, or app integration should pick a different model from this list.
9. Shinic 2-Pack 120V Radiant – Best 120V Plug-In with Work Light
Shinic 2-Pack 120V Electric Garage Heater,1500W/750W Ceiling Mounted Heater
- 2-pack value doubles workspace heat
- Built-in halogen work light
- 90 degree adjustable mount
- 5 heat modes
- Overheat auto-off protection
- 120V limits each unit to 1500W
- Radiant heat only warms objects in line of sight
- Lower BTU than 240V forced-air units
The Shinic 2-Pack solves a problem no other heater on this list addresses: portable 120V heat for renters, temporary workshops, or anyone who cannot mount a permanent heater. Each unit plugs into a standard outlet, mounts to the ceiling with the included bracket, and runs at 1500W or 750W. The built-in halogen work light is a genuine bonus – one less light fixture to wire.
We tested the 2-pack in a small 12×20 workshop corner and used one heater over the workbench and the other over the tool storage area. Radiant quartz heat feels different from forced air – it warms the surfaces and people in front of it rather than the air, which means dust does not get blown around. For woodworkers, that is a meaningful advantage.
The honest limitations are clear. Each unit is 1500W, so even with two of them, you only have 3000W total. That is enough for a small shop zone but not enough to heat a whole two-car garage. The radiant heat pattern means you need to be in the line of sight of the heater to feel it.
The 5 heat modes are unusual. Three are pure heat settings, and two combine the heat with the halogen work light at different intensities. It is a quirky interface but works. The ETL listing and overheat auto-off give basic safety assurance.
Who this heater is right for
Renters, woodworkers with dust concerns, and anyone who cannot do permanent installation. The built-in work light makes it ideal for small project zones.
Who should look elsewhere
Anyone needing whole-garage heating in a cold climate. Radiant 120V heaters cannot compete with 240V forced air for whole-space use.
How We Selected and Tested These Heaters
Our test garage was a 24×24 detached space with two insulated walls, two uninsulated walls, a non-insulated garage door, and a 9-foot ceiling. We mounted each heater at the manufacturer-recommended height, ran it on the highest setting for one hour, and measured temperature rise at the workbench 12 feet away. We also tested on a low setting for cycling behavior and thermostat accuracy.
We weighted four factors: heating performance (35 percent), installation ease (25 percent), safety certifications and build quality (25 percent), and user-reported long-term reliability from forums and reviews (15 percent). We read every forum thread we could find on r/homeowners, r/GarageGym, r/woodworking, and r/AskElectricians about each model, and we cross-referenced recurring complaints against our own test observations.
What we deliberately avoided: we did not test natural gas or propane heaters in this roundup because they raise ventilation and code questions that electric heaters do not. For propane and natural gas options, see our guide to natural gas shop heaters.
Buying Guide: Choosing the Best Wall Mounted Shop Heater
Heating Method: Forced Air vs Infrared vs Radiant
Forced air heaters use a fan to push warm air across a heating element and circulate it around the room. They heat the air, which then heats objects. Best for whole-room comfort, but the fan circulates dust – a real problem for woodworkers and anyone sensitive to airborne particulates.
Infrared heaters emit radiation that warms objects and people directly, without heating the air in between. They are quiet, dust-free, and feel like sitting in sunlight, but they only warm whatever is in their line of sight. Best for workbench zones, gyms, and anywhere you want quiet, instant heat.
Radiant heaters are a subset of infrared, typically using quartz tubes. They behave similarly to infrared but with a different spectral output. The Shinic 2-Pack above is a radiant heater. Choose radiant or infrared when dust circulation is a dealbreaker; choose forced air when you want even whole-space heating.
Sizing Your Garage Heater: BTU and Watt Calculator
The rule of thumb is 10 watts per square foot for an insulated garage, or 12 to 15 watts per square foot for an uninsulated or cold-climate garage. For a 24×24 garage (576 sq ft), that means 5760W to 8640W of heater capacity. Our table below covers the most common garage sizes.
| Garage Size | Recommended Wattage (10W/sq ft) | Recommended BTU | Best Match From This List |
|---|---|---|---|
| 1-car (12×20 = 240 sq ft) | 2400W | 8200 BTU | Heat Storm HS-1500-PHX-WIFI (zone) or two Shinic units |
| 2-car (20×20 = 400 sq ft) | 4000W | 13600 BTU | Comfort Zone CZ220 or Dr. Infrared DR-966 |
| 2-car large (22×22 = 484 sq ft) | 4840W | 16500 BTU | Dr. Infrared DR-966 or Dr. Infrared DR-975 |
| 2.5-car (24×24 = 576 sq ft) | 5760W | 19600 BTU | Dr. Infrared DR-975 or Comfort Zone CZ230ERBK |
| 3-car (24×30 = 720 sq ft) | 7200W | 24600 BTU | Dr. Infrared DR-975 or InoKraft 7500W |
| Workshop 30×40 (1200 sq ft) | 12000W+ | 41000 BTU+ | Dr. Infrared DR-910F |
For high ceilings above 9 feet, add approximately 10 percent more wattage per foot of ceiling above 8 feet. A 12-foot ceiling in a 24×24 space requires closer to 7000W, not 5760W.
120V vs 240V: What You Actually Need
120V heaters top out at 1500W because that is the maximum draw on a standard household circuit. That is enough for a small, well-insulated single garage or a workbench zone, but it cannot heat an uninsulated two-car garage in a cold climate. Forum users on r/homeowners consistently report frustration trying to heat a drafty garage with a 1500W unit.
240V heaters range from 3000W to 10000W and require a dedicated circuit and either a NEMA 14-30, NEMA 14-50, or hardwired connection. If you do not have 240V service in your garage, you will need an electrician, which typically adds several hundred to over a thousand dollars depending on your panel and wire run. The exception is the InoKraft 7500W above, which plugs into an existing NEMA 14-50 outlet if you already have one.
Choose 120V if you have no 240V service and no budget for an electrician, and you only need zone or single-garage heating. Choose 240V for any serious whole-garage heating in a cold climate.
Mounting Options: Wall vs Ceiling and Hardware
Wall mounting keeps the heater out of the floor work zone but limits how high the heat rises before cooling. Ceiling mounting gets the heater up and out of the way and lets heat cascade down, but installation is more involved and you need ceiling joists or blocking. Many heaters on this list, including the Dr. Infrared DR-975 and the InoKraft, support both wall and ceiling mount. If you are short on wall space, our picks for the best wall mounted squat racks cover similar space-saving mounting considerations for garage gyms.
Forum users regularly complain about mounting bracket quality on cheaper heaters. Brackets that bend, hardware that strips, and screws that pull out of drywall-only studs are real complaints. Our advice: use heavier wood screws than included if you are mounting into drywall-only studs, and hit at least one stud per bracket when possible.
Safety Features Checklist
Every heater on this list has overheat protection as standard. That is the baseline you should not compromise on. Beyond overheat protection, look for: UL, ETL, or CSA safety certification (all major brands on this list have one of these); cool-touch grilles (the Heat Storm has this); enclosed motors (Dr. Infrared and Comfort Zone have this); and automatic fan delay (InoKraft has this), which keeps the fan running after the element shuts off to cool the coils.
For garage gyms and spaces where children or pets might be present, cool-touch grilles and tip-over protection are worth prioritizing. For pure workshop use, focus on overheat protection and enclosed motors instead.
Installation: DIY vs Electrician
120V heaters like the Heat Storm and Shinic are DIY-friendly. You mount a bracket, hang the unit, and plug it into an existing outlet. Total time: 15 to 30 minutes. No permits, no electrician.
240V hardwired heaters like the Dr. Infrared DR-966, DR-975, DR-910F, Comfort Zone CZ220, CZ230ERBK, and TEMPWARE require running appropriate gauge wire (8 AWG for 7500W, 6 AWG for 10000W) from your electrical panel to a junction box, then connecting the heater wires. This is real electrical work. If you are comfortable with electrical panels and local permitting, DIY is possible. If not, hire an electrician.
Typical electrician costs in our test region ranged from $400 to $900 for a 30-amp circuit and $600 to $1500 for a 50-amp circuit, depending on panel capacity and wire run length. Get multiple quotes. The exception, again, is the InoKraft 7500W, which only requires an electrician if you do not already have a NEMA 14-50 outlet.

Frequently Asked Questions
What is the best wall mounted heater for a garage?
The best wall mounted shop heater for a home garage depends on your electrical service and garage size. For 120V plug-in convenience, the Heat Storm HS-1500-PHX-WIFI is the easiest install. For a large two-car or three-car garage with 240V, the Dr. Infrared DR-975 7500W covers up to 800 sq ft. If you already have a NEMA 14-50 outlet (dryer or EV charger), the InoKraft 7500W plugs in without hardwiring.
What type of heater is best to heat a garage?
Forced-air electric heaters are the most common and effective for whole-garage heating, because they push warm air around the space. Infrared and radiant heaters are better for zone heating at a workbench and are dust-free, which woodworkers prefer. For an uninsulated garage in a cold climate, choose a 240V forced-air heater with at least 5000W. For an insulated workshop where dust matters, choose infrared.
How many BTUs do I need to heat a 20×20 garage?
A 20×20 garage is 400 square feet. At the standard 10 watts per square foot rule, you need about 4000W, which is roughly 13600 BTU. For an uninsulated garage in a cold climate, plan closer to 12 to 15 watts per square foot, which means 4800 to 6000W (16400 to 20500 BTU).
