The Best Electric Garage & Workshop Heaters (120V/240V) of 2026
Seven electric heaters for garages and shops, from hardwired 240V unit heaters to silent 120V radiant spot heat, ranked on noise, safety, output, installation and value.
We may earn a commission when you buy through links on this page. Our editorial rankings are maintained separately from retailer relationships.
A garage is a hard room to heat. It is big, often poorly insulated, and full of dust, solvents and fuel. Electric heaters avoid combustion fumes, which is the main reason woodworkers and home mechanics choose them, but the right one depends mostly on your wiring.
If you can get a 240V circuit, you can heat a whole one- to three-car space with a ceiling or wall unit. If you are limited to a standard 120V outlet, 1,500W is the ceiling, and you are better off warming yourself or your bench than the whole room.
This guide ranks seven options across both camps. Each pick lists who it suits and who should skip it, including the installation work that comes with the higher-output units.

Dr. Infrared Heater DR-966
The best-documented hardwired 240V shop heater, with sturdy hardware and a dust-ready motor.
Full product review →
7.0
/10
Lowest verified price
$175.99
at Amazon
A 3,000/6,000W hardwired 240V wall or ceiling unit heater with a thermostat, adjustable louvers and a sealed motor. Built for one- to two-car garages and woodshops.
Why we like it
Its record is the strongest of any 240V unit we looked at. Bob Vila named it best commercial-grade and called it one of the nicest hardwired shop heaters it had tried, citing higher-quality hardware and locking angle knobs. Popular Science named it best 240V and Woodsmith listed it as runner-up. Dr. Heater USA lists it as UL and cUL listed.
The totally enclosed ball-bearing motor suits a dusty shop, and the two power settings (3,000W and 6,000W) let you hold a space steady rather than run flat out. Tilting louvers let you aim the heat.
What to know
Skip it if you cannot run or already lack a 240V circuit, or if you want a remote or a precise numbered thermostat.
Pros
- UL and cUL listing from the manufacturer
- Three independent recommendations
- Enclosed motor suited to shop dust
- 3,000W and 6,000W settings
- Tilting louvers to aim heat
Cons
- Thermostat has no numbered settings and testers found it finicky
- No remote
- Hardwired, so most buyers need an electrician
- Fan-forced, so it is not quiet

Best for Large Garages (Remote & Timer)
Comfort Zone CZ230ER
The most output for the money, with a digital thermostat, timer and remote.
Full product review →

/10
Lowest verified price
$144.97
at Amazon
A 7,500W hardwired 240V ceiling-mount heater with a digital thermostat, 12-hour timer, remote and fan-only mode. Aimed at large or drafty garages.
Why we like it
At 7,500W (about 25,600 BTU), it has the highest output in this guide and the lowest cost per watt. Bob Vila's best-overall pick links this model and says it proved to put out plenty of heat. It has overheat shutoff, and the Amazon listing confirms a digital thermostat, timer and remote, which is rare for a hardwired shop heater.
For a two- to three-car or drafty garage, the extra capacity is the point.
What to know
Skip it if your circuit can't handle about 31A, or if you want a heater with a manufacturer-confirmed safety listing. Its ETL listing comes from retailers, not Comfort Zone, and some retailers list the model as discontinued, so availability may tighten.
Pros
- Highest output here, about 7,500W
- Digital thermostat, 12-hour timer and remote
- Lowest cost per watt
- Overheat shutoff
- Sold and shipped by Amazon at a mid-range price
Cons
- Draws about 31A and needs a 40A circuit
- Wire and clamp not included
- No memory after a power loss
- Some retailers list it as discontinued

Best Budget Spot Heater
Comfort Zone CZQTV5M
Silent overhead heat for a workbench or garage gym at a budget price.
Full product review →
6.7
/10
Lowest verified price
$59.25
at Amazon
A 120V ceiling-mount dual-quartz radiant heater with two settings, a tilting head and a built-in light. It heats a spot, not a whole garage.
Why we like it
Bob Vila picked it as best for garage gyms and said it produces silent heat with no fan blowing at you. Popular Science named it best ceiling mount. The dual quartz tubes run at 760 or 1,500W, the head tilts 90 degrees, and a metal grille and overheat protection come standard.
It plugs into a standard outlet and costs far less than anything else here, so it is an easy way to warm a bench or lifting area.
What to know
Skip it if you want to heat a whole garage or need a thermostat. A UL or ETL listing is not confirmed, and Bob Vila reports weak bracket screws, so mount it on the ceiling, not a wall.
Pros
- Silent, no blower or dust stirring
- Budget price
- Tilting head and built-in light
- Plugs into a standard 120V outlet
Cons
- No thermostat, two heat settings only
- Heats a small area
- Safety listing not confirmed
- Weak bracket screws

Best 120V Smart Wall Heater
Heat Storm HS-1500-PHX-WIFI
The most widely recommended 120V garage heater, with app and voice control.
Full product review →
6.3
/10
Lowest verified price
$134.99
at Amazon
A slim 1,500W wall-mounted infrared heater with Wi-Fi, Alexa and Google control and a 40-99°F thermostat. Best for small or insulated garages.
Why we like it
Bob Vila rated it best overall in its electric garage heater guide, and Popular Science, Woodsmith, Reviewed and This Old House also recommend it. The thermostat holds a set temperature, the grill is touch-safe, and you can schedule it from an app, which helps if you want the garage warm before you walk out.
It needs only a standard outlet, so it suits garages and garage gyms with no 240V option.
What to know
Skip it for a large or uninsulated garage, where 1,500W won't keep up. A UL or ETL listing is not confirmed, Woodsmith lists no tip-over feature while Bob Vila reports one, and an owner reports some fan noise.
Pros
- Broadest set of recommendations among 120V picks
- Digital thermostat with Wi-Fi and voice control
- Touch-safe grill
- Plugs into a standard outlet
- Overheat protection
Cons
- Only about a 3 ft cord
- Pricey for 1,500W
- Not silent per one owner report
- Safety listing not confirmed

Best Indoor/Outdoor Radiant Heater
Briza Infrared Carbon Patio/Garage Heater 1500W
Silent radiant heat you aim at yourself, for open-door or uninsulated garages.
Full product review →
6.7
/10
Lowest verified price
$198.88
at Amazon
A 1,500W fanless carbon-lamp infrared heater rated IP55, with a remote, timer and tripod or wall/ceiling mounting.
Why we like it
Car and Driver chose it after thermal-camera testing, Bob Vila named it best indoor/outdoor, and Popular Science named it best freestanding. Radiant heat warms people and objects directly, so it still works when the door is open and the air is cold. With no blower, it doesn't stir up shop dust.
It comes with a remote, a 1-9 hour timer, and tip-over shutoff.
What to know
Skip it if you want a thermostat or whole-room heat. Its effective range is about 6 ft, and a UL or ETL listing is not confirmed.
Pros
- Silent, fanless operation
- IP55 weather rating
- Remote and 1-9 hour timer
- Tip-over shutoff
- Tripod or wall/ceiling mounting
Cons
- No thermostat
- Effective range about 6 ft
- Pricey
- Safety listing not confirmed

Best Plug-In 240V Portable

240V power without hardwiring, if you already have a 6-30R outlet.

/10
Lowest verified price
$151.42
at Amazon
A portable 5,600W fan-forced 240V heater with a 6 ft cord and NEMA 6-30P plug, a 37-113°F thermostat and finger-proof grills. Marketed as infrared, it is a fan heater.
Why we like it
Bob Vila named it best infrared in its best-garage-heater guide. At 5,600W it heats far more than any 120V unit, and retailers list it as UL and cUL listed. The plug-in design means no hardwiring if your shop has a welder or compressor outlet.
It has an analog dial thermostat and an On/Auto fan.
What to know
Skip it if you lack a 30A 240V 6-30R outlet or want to avoid floor-level heat near solvent vapors. The manual says floor use only, so follow it on mounting, and no tip-over switch is confirmed.
Pros
- 5,600W output
- Plugs into a 6-30R outlet
- Thermostat 37-113°F
- Listed UL and cUL by retailers
- Finger-proof grills
Cons
- Needs a 30A 240V outlet, and testers had trouble finding one
- Floor use only per the manual
- No tip-over switch confirmed
- Fan noise

Best Recessed In-Wall Heater for Finished Garages
Broan-NuTone 198
A flush, permanent wall heater for finished attached garages.
Full product review →
6.3
/10
Lowest verified price
$389.00
at Amazon
A recessed 4,000W 240V fan-forced in-wall heater with an infinitely variable thermostat, fan delay and manual-reset overload protection.
Why we like it
Bob Vila picked it as best wall-mounted heater. Broan-NuTone lists it as UL Listed, and it has an 18-gauge steel grille with a removable faceplate for cleaning. It sits in the wall, so it takes no floor or bench space.
The fan delay clears residual heat, and the thermostat has no fixed steps.
What to know
Skip it for an unfinished garage, a large space, or a tight budget. It is rated for 265-400 sq ft, costs a lot, and is hardwired.
Pros
- Recessed, takes no floor space
- UL Listed with manual-reset overload protection
- Steel grille, easy to clean
- Variable thermostat with fan delay
Cons
- Expensive
- Rated for 265-400 sq ft
- Needs hardwiring, possibly an electrician
- Works best mounted high on the wall

Our process
How we review space heaters
PickMetric compared products using independent tests and reviews (Bob Vila, Popular Science, Woodsmith, Car and Driver, Reviewed, This Old House), manufacturer spec sheets, retailer listings and owner feedback. Prices and stock were checked against Amazon on October 31, 2026.
Six criteria were weighted: noise (25%), safety (25%), heating performance (20%), ease of installation and controls (12%), value including likely electrician cost (12%), and health and materials (6%). Noise and safety carry the most weight because a shop heater runs beside you for hours and sits near dust and solvents.
How We Picked
We started with 15 candidates and compared independent tests and reviews from Bob Vila, Popular Science, Woodsmith, Car and Driver, Reviewed, This Old House and TechGearLab, plus manufacturer specs, retailer listings, recall searches and owner feedback.
Every pick was then challenged in a structured review before publication, and the review changed the lineup. The Comfort Zone CZ230ER was first ranked best overall, but its safety listing came only from retailers and it rested on one tester. We moved the Dr. Infrared DR-966, which has a manufacturer-confirmed UL/cUL listing and three recommendations, into first place and lowered the CZ230ER's safety score.
The review also corrected the Heat Storm Phoenix's noise rating, which had been based on a fan claim the evidence did not support, and renamed the CZQTV5M a budget spot heater so no one mistakes it for a whole-garage option. Products that were out of stock or lacked support were left out.
What to Look For
Match the heater to your wiring
A standard 120V circuit supports about 1,500W, which is enough for a bench, a gym corner or a small insulated garage. For a typical one- to three-car garage you need 240V, which supports 3,000 to 7,500W. Hardwired units usually require an electrician, and plug-in 240V units need a matching outlet such as a 6-30R.
Size the output to the space
Garages lose heat quickly. Uninsulated or drafty spaces need more watts than manufacturer coverage claims suggest, and those claims vary. Treat 1,500W as spot or small-room heat.
Radiant or fan-forced
Fan-forced heaters warm the air and hold a thermostat setting, but they are noisy. Radiant quartz and carbon heaters are silent and warm you directly, but they have a short range and often no thermostat. Some units sold as infrared, such as the DR-966 and DR-988, are fan-forced.
Safety features
Look for a UL, cUL or ETL listing, overheat protection, and tip-over shutoff on anything that sits on the floor. Mounting units off the floor keeps them away from solvent vapors and fuel. Do not use a heater near open containers of flammable liquids.
Controls
A thermostat saves energy and holds a steady temperature. Remotes, timers and apps are useful if you want the space warm before you arrive.
Health, Materials & Safety
Electric heaters produce no combustion emissions, which is the main advantage over propane and kerosene units in an enclosed garage. A CPSC search found no recalls for the picks in this guide.
Dust matters in a woodshop. The DR-966 has a totally enclosed, thermally protected motor, and the silent radiant picks (CZQTV5M and Briza) have no blower to stir dust up. The Broan-NuTone 198 has a steel grille that comes off for cleaning.
Safety listings differ. The DR-966 is UL and cUL listed per the manufacturer, and the Broan-NuTone 198 is UL Listed. The DR-988 is listed per retailers, and the CZ230ER is described as ETL by retailers. A listing is not confirmed for the Phoenix, the Briza or the CZQTV5M, so buyers who want a listed heater should lean toward the 240V picks.
Other Electric Garage & Workshop Heaters (120V/240V) We Considered
Comfort Zone CZ220: a budget whole-garage 240V option, but Amazon shows it out of stock until November 10, 2026. It is worth checking once it returns.
Heat Storm HS-6000-GC: a quiet 240V unit, but it appears to be unavailable new from major retailers, and no safety listing was confirmed.
Fahrenheat FUH54: out of stock on Amazon, with other sellers asking very high prices.
NewAir G56: no independent test and conflicting coverage claims. The tested Dr. Infrared units fill this role.
King KB2407-1-B2-ECO: roughly ten times the price of the CZ230ER for the same output, with no independent test.
Lasko 755320: Bob Vila and TechGearLab report it has no tip-over switch, which is a poor fit for a garage floor.
Isiler 1500W ceramic: out of stock on Amazon, and testers say it only warms a bench.
Bio Green Palma Pal: a freeze-protection greenhouse heater with first-use off-gassing and no tip-over switch, at a high price for 1,500W.
FAQ
Do I need a 240V heater for my garage?
For a whole one- to three-car garage, usually yes. A 120V heater tops out around 1,500W, which suits a small insulated space or a single work area.
Can I install a hardwired heater myself?
Wiring rules vary, and these units draw high current. The DR-966 and CZ230ER are hardwired, and the CZ230ER draws about 31A, so most buyers should hire a licensed electrician.
Are infrared heaters better for garages?
Radiant heaters are silent and warm you directly, which helps in a drafty or open-door garage. They do not warm the whole room. Note that the DR-966 and DR-988 are marketed as infrared but use fans.
Is it safe to run an electric heater near woodworking dust or solvents?
Electric heaters avoid open flames, but dust and vapors are still a concern. Mount heaters off the floor where possible, keep solvents away, and clear dust from grills and louvers.
How much does it cost to run a garage heater?
Cost depends on wattage, run time and your local electricity rate. A 6,000W heater at full output uses six kilowatt-hours per hour, so a thermostat and good insulation make a real difference.
Can I leave a garage heater on all day?
Only if the manufacturer says so. Use a thermostat or timer, and do not leave a heater running unattended in a space with flammable materials.
Bottom line
For most owners with a 240V circuit available, the Dr. Infrared DR-966 is the safest all-round choice: documented listing, sturdy build and plenty of heat. Choose the Comfort Zone CZ230ER if you need more output and a remote. On a 120V circuit, the Heat Storm Phoenix suits small insulated spaces, while the Comfort Zone CZQTV5M and the Briza give quiet, targeted warmth. Whatever you buy, check your circuit and the unit's amperage first, and hire an electrician for hardwired installs.
