The short answer

For most bedrooms and living rooms the best all-around pick in 2026 is the DREO 1500W PTC Ceramic Space Heater, a quiet, thermostat-controlled unit that heats up fast and runs at just 34 dB so it will not disturb sleep or a video call. Need to warm an entire large room instead of a single desk? The PELONIS 30-inch Ceramic Tower Space Heater oscillates across roughly 280 square feet, and the Dr Infrared Heater DR-968 pairs quartz infrared with a PTC element for whole-room coverage on wheels. Want a safer option to leave running overnight or near kids and pets, without an exposed glowing element? The PELONIS Electric Oil Filled Radiator holds heat in its fins even after it cycles off. Heating a garage, workshop or detached shop instead of a living space? The Comfort Zone and VEVOR 240-volt hardwired units are built for that job specifically, not for a bedroom outlet. On a tight budget, the Amazon Basics and GiveBest ceramic heaters cover a single small room for a fraction of the cost of the premium picks. Below we compare all 10 on heating method, coverage area, and which room or use case each one suits best.

Best overallDREO 1500W PTC Ceramic Space Heater with Thermostat and Remote

★★★★★Tier score 9.4/10
1500W Hyperamics PTC ceramic core34 dB brushless DC motor41-95F thermostat, 1F incrementsTilt-detection tip-over sensorRemote, timer and child lock

Why we picked it: The DREO 1500W PTC Ceramic Space Heater is the strongest all-around pick in this guide because it balances genuinely fast heat with genuinely quiet operation, two things that are usually a trade-off in this category. Its Hyperamics PTC system combined with a funnel-shaped outlet is built to throw warm air noticeably farther than a typical small ceramic heater, while a brushless DC motor and a winglet fan design keep noise down to about 34 dB, quiet enough to run overnight in a bedroom or during a work call without becoming a distraction. The electronic thermostat holds a set target from 41 to 95 degrees Fahrenheit in single-degree increments rather than the vague low or high dial found on cheaper units, so a room stays at a consistent temperature instead of overshooting and cycling constantly. Safety features include a tilt-detection sensor that shuts the unit off if it is knocked over, V0 flame-retardant housing, and overheat protection, all backed by ETL certification. A remote, 12-hour timer, memory function and child lock round out a feature set built for daily bedroom or home-office use rather than occasional emergency heating.

Pros
  • Quiet 34 dB operation suits bedrooms and desks without becoming a distraction
  • Precise 1F thermostat increments hold a steady room temperature
  • Tilt-detection tip-over sensor plus ETL-certified overheat protection
  • Remote, timer, memory function and child lock included
Cons
  • 1500W ceramic heaters like this one are best suited to a single room, not a whole floor
  • Higher price than basic no-frills ceramic heaters without a thermostat display
Who should buy it

Anyone heating a single bedroom, home office or living room who wants quiet, precise, app-free thermostat control.

Who should avoid it

Buyers who need to heat a large open floor plan or an entire basement in one pass.

Key specs: 1500W PTC ceramic - 34 dB lowest noise level - thermostat range 41-95F in 1F increments - tilt-detection tip-over sensor - remote, timer, child lock

Best large roomsPELONIS 30-inch Ceramic Tower Space Heater for Large Room

★★★★★Tier score 9.2/10
30-inch tower with 75-degree oscillationCovers up to 280 sq ftHeats to 70F in about 3 seconds4 modes: High, Low, ECO, FanUnder 55 dB operation

Why we picked it: The PELONIS 30-inch Ceramic Tower Space Heater is built specifically for rooms too large for a compact desktop unit to handle evenly. Its 30-inch tower shape combined with 75 degrees of oscillation is rated to cover up to 280 square feet, which comfortably reaches a large bedroom, an open living room or a finished basement corner rather than just the few feet directly in front of the heater. PELONIS says the ceramic element and roughly 26 percent more hot-air vents than a standard tower let it bring a room up to 70 degrees Fahrenheit in about three seconds of run time, and four selectable modes, High, Low, ECO and Fan-only, let you dial in exactly how much heat versus energy use you want at any given moment. Operating noise stays under 55 dB even on the higher settings, which is louder than the DREO's bedroom-tuned 34 dB but still reasonable for a shared living space. A remote, 12-hour timer, digital display and both tip-over and overheat protection round out the safety and convenience features.

Pros
  • 75-degree oscillation and 30-inch tower height spread heat across up to 280 sq ft
  • Heats a room to 70F in about 3 seconds per PELONIS testing
  • 4 selectable modes including a dedicated ECO efficiency setting
  • Remote control and 12-hour timer for hands-off operation
Cons
  • Larger footprint takes up more floor space than a compact desktop ceramic heater
  • Under 55 dB is audible enough that light sleepers may prefer the quieter DREO
Who should buy it

Anyone heating a large bedroom, open living room or finished basement space who needs real coverage, not just spot heat.

Who should avoid it

Buyers who only need to warm the area directly around a desk or armchair and do not need 280 sq ft of coverage.

Key specs: 30-inch ceramic tower - up to 280 sq ft coverage - 75-degree oscillation - 4 modes (High, Low, ECO, Fan) - under 55 dB - remote and 12-hour timer

whole-room infraredS-Tier

Best whole-room infraredDr Infrared Heater DR-968 Portable Space Heater

★★★★★Tier score 9.1/10
Dual infrared quartz tube + PTC heatingRated around 5200 BTU output39 dB high-pressure blowerCaster wheels for repositioningLifetime washable filter

Why we picked it: The Dr Infrared Heater DR-968 takes a different approach from the ceramic towers in this guide by combining an infrared quartz tube with a PTC heating element inside a furniture-style wood cabinet, which its maker says produces around 60 percent more heat output than a PTC-only design of the same wattage, rated at roughly 5200 BTU. Infrared heat warms objects and people directly rather than only the air passing through the unit, so a room can feel warm faster even before the ambient air temperature has fully risen. A high-pressure, low-noise blower keeps operating sound to about 39 dB while still pushing that heat throughout a larger room, and caster wheels make it easy to roll the roughly 19 lb cabinet from room to room rather than carrying it. An electronic thermostat spans 50 to 85 degrees Fahrenheit, a 12-hour automatic shut-off timer adds a safety layer for unattended use, and a lifetime filter means there is no replacement filter to buy over the life of the unit.

Pros
  • Dual infrared quartz plus PTC design delivers meaningfully more heat output at the same wattage
  • Cabinet style with casters looks like furniture and rolls easily between rooms
  • 39 dB blower is quiet for a unit rated at this heat output
  • Lifetime washable filter avoids ongoing filter replacement costs
Cons
  • Cabinet design is bulkier and heavier than a slim ceramic tower or compact desktop unit
  • Wood-look housing will not match every decor the way a plain black or white heater does
Who should buy it

Buyers who want genuine whole-room infrared heat output in a furniture-style cabinet that can be rolled between rooms.

Who should avoid it

Buyers who want the smallest possible footprint or need to tuck a heater into a tight desk or shelf space.

Key specs: 1500W dual infrared quartz + PTC heating - approx. 5200 BTU output - 39 dB blower noise - caster wheels - lifetime washable filter - 12-hour timer

bedroom oscillatingA-Tier

Best bedroom oscillatingLasko 1500W Ceramic Tower Space Heater with Widespread Oscillation

★★★★★Tier score 8.9/10
1500W ceramic heating elementWidespread oscillationRemote control includedAdjustable thermostatBuilt-in timer

Why we picked it: The Lasko 1500W Ceramic Tower Space Heater is a long-running, widely trusted tower design that pairs a 1500W ceramic element with widespread oscillation to spread heat across a bedroom or living room rather than aiming it in one fixed direction. The included remote lets you adjust temperature and fan speed from a couch or bed without getting up, and the adjustable thermostat cycles the heater on and off to hold a set comfort level instead of running at full power continuously. A built-in timer allows the unit to shut off automatically after a set period, which is a useful safety and energy-saving habit for overnight use. As one of the more established names in home heating, it is a dependable middle-ground choice between the premium DREO and the large-room PELONIS tower, without stepping up to either extreme of price or coverage.

Pros
  • Widespread oscillation distributes heat across the room instead of one fixed direction
  • Remote control adjusts settings without needing to get up
  • Adjustable thermostat and timer support both comfort and energy savings
  • Established, widely available brand with broad parts and support history
Cons
  • Tower height and footprint are larger than a compact desktop ceramic heater
  • Does not include the extra-quiet sub-35 dB tuning of the DREO for light sleepers
Who should buy it

Buyers who want a dependable, well-known oscillating tower heater for a bedroom or living room at a mid-range price.

Who should avoid it

Buyers who specifically need the quietest possible bedroom operation or the largest possible room coverage.

Key specs: 1500W ceramic heating element - widespread oscillation - remote control - adjustable thermostat - built-in timer

overnight and nursery safeA-Tier

Best overnight and nursery safePELONIS Electric Oil Filled Radiator Heater

★★★★★Tier score 8.8/10
1500W oil-filled radiator design3 heat modes: 600W, 900W, 1500WNo exposed glowing heating element4 heavy-duty castersTip-over protection

Why we picked it: The PELONIS Electric Oil Filled Radiator takes a fundamentally different approach from every ceramic or infrared heater in this guide by sealing its heating element inside oil-filled metal fins rather than exposing a glowing coil or ceramic plate to open air. That design means the surface stays cooler to the touch than a ceramic heater's grille, and because the oil retains heat, the radiator keeps releasing warmth for a while even after the thermostat cycles it off, which reduces how often the element actually needs to run. Three selectable modes at 600W, 900W and 1500W, usable individually or in combination, let you dial in exactly how much heating power a room needs rather than only choosing between low and high. Four heavy-duty casters and a front carrying handle make it easy to move between rooms, and tip-over protection cuts power automatically if the unit is knocked over. This design is a common recommendation for nurseries, kids' rooms and any space where the heater will run unattended for long stretches, since there is no exposed element to touch.

Pros
  • No exposed glowing element makes it a safer overnight option for kids and pets
  • Oil retains heat and keeps warming a room even after the thermostat cycles off
  • Three combinable wattage settings, 600W, 900W and 1500W, for precise heat output
  • Casters and a carrying handle make repositioning between rooms easy
Cons
  • Heats up more slowly than a ceramic or infrared unit since the oil has to warm through first
  • Heavier and bulkier than a compact ceramic tower or desktop heater
Who should buy it

Parents, pet owners and anyone who wants a heater that can run unattended overnight without an exposed hot surface.

Who should avoid it

Buyers who want the fastest possible warm-up time and do not mind an exposed heating element.

Key specs: 1500W oil-filled radiator - 600W/900W/1500W selectable modes - no exposed heating element - 4 casters plus carry handle - tip-over protection

personal desk heaterA-Tier

Best personal desk heaterBLACK+DECKER Infrared Radiant Quartz Tower Heater

★★★★★Tier score 8.6/10
Infrared radiant quartz element1500W high / 750W low settingsAdjustable thermostatOnly 5 lbs, easy to carryCompact slim tower shape

Why we picked it: The BLACK+DECKER Infrared Radiant Quartz Tower Heater is built for personal, close-range warmth rather than heating an entire room, which makes it a natural fit for a cold home office, a garage workbench, or a specific chilly corner of a larger space. At just 5 lbs it is genuinely easy to pick up and carry from room to room throughout the day, unlike the heavier cabinet-style and radiator units in this guide. Two heat settings, 750W low and 1500W high, are controlled through an adjustable thermostat, giving a simple but effective way to match output to how cold the space actually is. Because infrared quartz heats people and objects directly rather than warming the surrounding air first, it delivers a noticeably quick sense of warmth at close range even in a space that is not fully heated overall.

Pros
  • Infrared quartz delivers quick, direct warmth at close range
  • Only 5 lbs, the lightest and most portable pick in this guide
  • Two simple heat settings, 750W and 1500W, with an adjustable thermostat
  • Slim tower footprint fits under a desk or beside a chair
Cons
  • Designed for personal, close-range warmth rather than heating a whole room
  • Fewer smart features, no remote or digital display, compared with pricier towers
Who should buy it

Anyone who wants quick, direct personal warmth at a desk, workbench or specific cold spot without heating an entire room.

Who should avoid it

Buyers who need to warm an entire bedroom or living room rather than a single personal space.

Key specs: 1500W/750W infrared quartz heating - adjustable thermostat - 5 lbs - slim tower design

Best budget compactAmazon Basics Ceramic Space Heater

★★★★★Tier score 8.4/10
1500W/900W/Fan-only settingsCompact 7.52 x 6.34 x 9.45 inOverheat and tip-over protectionNon-oscillating direct heat3 lb lightweight body

Why we picked it: The Amazon Basics Ceramic Space Heater is a straightforward, no-frills budget pick for anyone who just needs a compact unit to take the chill off a small room or a spot under a desk. Three settings, High at 1500W, Low at 900W, and Fan-only for air circulation without heat, cover the basic range most small-room users need without any extra digital features to learn. At about 7.5 by 6.3 by 9.5 inches and just 3 lbs, it is one of the smallest and most portable heaters in this guide, easy to tuck under a desk or move between rooms. Ceramic heating brings the unit up to temperature in minutes, and Amazon Basics includes both overheat and tip-over protection as standard safety features even at this price point. It is non-oscillating, so it throws heat in one direction rather than spreading it across a room, which is fine for close-range personal use but is a real limitation for anyone trying to heat a larger space evenly.

Pros
  • Genuinely low price for a heater with real overheat and tip-over protection
  • Compact 3 lb body is easy to move between rooms or tuck under a desk
  • Simple 3-setting design, High, Low, Fan-only, with no learning curve
  • Fast ceramic heat-up time for close-range personal use
Cons
  • Non-oscillating design only heats in one direction rather than spreading across a room
  • No thermostat display or remote, just basic dial-style settings
Who should buy it

Budget-conscious buyers who want a simple, safe, compact heater for a small room or under a desk.

Who should avoid it

Buyers who want oscillation, a digital thermostat, or coverage large enough for a big bedroom or living room.

Key specs: 1500W/900W/Fan-only ceramic heating - 7.52 x 6.34 x 9.45 in - 3 lbs - overheat and tip-over protection - non-oscillating

★★★★★Tier score 8.2/10
1500W/750W dual heating modesDoubles as a cool-air fanAutomatic thermostat cyclingV0 flame retardant housingRated for up to 200 sq ft

Why we picked it: The GiveBest Portable Electric Space Heater is a two-in-one budget pick that works as both a heater in winter and a plain cooling fan the rest of the year, which stretches its usefulness well beyond the cold months for buyers who want one small appliance instead of two. Dual heating modes at 1500W and 750W are managed by an automatic thermostat that cycles the unit on and off to hold a preset temperature rather than running continuously, and GiveBest rates it to heat up to 200 square feet, enough for most single bedrooms, home offices or bathrooms. Safety features include V0 flame-retardant housing, automatic overheat shut-off, and tip-over protection that cuts power if the unit is knocked over and restores it automatically once uprighted. GiveBest also states the operating volume stays quieter than typical conversation level, making it a reasonable choice for a bedroom used while sleeping or working.

Pros
  • Doubles as a cooling fan in warmer months, extending its use beyond winter
  • Automatic thermostat cycling maintains a set temperature without manual adjustment
  • Rated for up to 200 sq ft, enough for most single bedrooms or offices
  • Tip-over protection restores power automatically once the unit is uprighted
Cons
  • 200 sq ft rating is not enough for large or open-plan rooms
  • Plastic ABS housing feels less premium than metal-bodied ceramic towers
Who should buy it

Budget-conscious buyers who want a heater that also works as a fan for year-round use in a single room.

Who should avoid it

Buyers who need to heat a room larger than about 200 sq ft in one pass.

Key specs: 1500W/750W dual mode - doubles as cooling fan - rated up to 200 sq ft - automatic thermostat - tip-over protection with auto-restore

Best garage and workshopComfort Zone Hard-Wired Ceiling Mount Garage Space Heater, 7500W

★★★★★Tier score 8.5/10
7500W, 240V hardwired ceiling unitCovers up to 1250 sq ftDigital thermostat with remote12-hour timerOverheat protection

Why we picked it: The Comfort Zone Hard-Wired Ceiling Mount Garage Space Heater is built for an entirely different job than the plug-in room heaters in this guide: it is a 240-volt, hardwired unit designed to be professionally installed in a garage, workshop or warehouse ceiling rather than plugged into a household outlet. Mounting it overhead keeps the heater out of the way of parked vehicles, workbenches and foot traffic while still delivering serious heat output, rated to cover up to 1250 square feet, which is enough for a multi-car garage or a good-sized workshop. A digital thermostat with a full-function remote lets you set and adjust the temperature without climbing a ladder to reach the unit itself, and a 12-hour timer adds scheduling flexibility for a space that is not occupied around the clock. Because it requires a 240-volt hardwired electrical connection, installation is a job for a licensed electrician rather than a simple plug-and-play setup, which is the trade-off for the much higher heat output than any 120-volt plug-in heater can deliver.

Pros
  • 7500W of output covers up to 1250 sq ft, far beyond what a plug-in room heater can manage
  • Ceiling mounting keeps the unit safely out of the way in a working garage or shop
  • Digital thermostat and remote allow adjustment without reaching the unit
  • 12-hour timer suits spaces that are not used around the clock
Cons
  • Requires a 240-volt hardwired electrical connection installed by a licensed electrician
  • Not a plug-in option, so it is not a fit for renters or anyone wanting a simple setup
Who should buy it

Garage, workshop or warehouse owners who need serious heat output installed permanently overhead.

Who should avoid it

Anyone who wants a simple plug-in heater for a bedroom, office or living room rather than a hardwired 240V installation.

Key specs: 7500W, 240V hardwired - covers up to 1250 sq ft - digital thermostat with remote - 12-hour timer - ceiling mount installation

Best smaller shop and workshopVEVOR Electric Garage Heater, 5000W Wall and Ceiling Mount

★★★★★Tier score 8.3/10
5000W, 240V hardwired unitWall or ceiling mount optionsDigital display with remote2 adjustable power levels9-hour timer, ETL listed

Why we picked it: The VEVOR Electric Garage Heater is a smaller-capacity alternative to the Comfort Zone unit above, sized for a single-car garage, a home workshop, or a shed rather than a full multi-bay space. At 5000W and 240 volts, VEVOR rates it to cover roughly 50 square meters, about 538 square feet, and two adjustable power levels let you match output to how cold the space actually gets rather than running at full capacity every time. It can be mounted on either a wall or a ceiling depending on the layout of the room, which gives more installation flexibility than a ceiling-only design. A digital display with remote control and intelligent temperature regulation keeps the room within about 2 degrees Fahrenheit of the target setting, and a 9-hour timer plus ETL listing round out the feature set. As with the Comfort Zone unit, it requires a hardwired 240-volt connection rather than a standard household outlet, so installation needs a licensed electrician.

Pros
  • Wall or ceiling mounting gives more installation flexibility than a ceiling-only unit
  • Precise temperature regulation holds within about 2F of the target setting
  • Two adjustable power levels match output to the size of the space
  • ETL listed with a 9-hour timer for scheduled operation
Cons
  • Requires a hardwired 240-volt connection and professional installation, same as the Comfort Zone unit
  • Lower maximum coverage than the 7500W Comfort Zone unit for very large garages
Who should buy it

Owners of a single-car garage, workshop or shed who want a permanently mounted 240V heater sized to a smaller space.

Who should avoid it

Owners of a large multi-car garage or warehouse who need the higher coverage of the 7500W Comfort Zone unit.

Key specs: 5000W, 240V hardwired - wall or ceiling mount - approx. 538 sq ft coverage - digital display with remote - 9-hour timer, ETL listed

Common questionsFrequently asked questions

Is it safe to leave a space heater running overnight?

Only with a heater that has both tip-over and overheat protection, and ideally one without an exposed glowing element for anyone who might bump into it in the dark, which is why an oil-filled radiator like the PELONIS pick in this guide is a common recommendation for overnight nursery or bedroom use. Always plug the heater directly into a wall outlet rather than an extension cord or power strip, keep it at least 3 feet from bedding, curtains and furniture, and never leave a heater running in a room with no smoke detector.

How many square feet can a typical 1500W space heater actually cover?

Most 1500W plug-in ceramic or infrared heaters are rated for somewhere between 150 and 300 square feet depending on the specific design, with compact units like the Amazon Basics and GiveBest picks suited to a single small room and oscillating towers like the PELONIS 30-inch model reaching closer to 280 square feet. For anything larger, such as an open-concept living area or a garage, a single 120-volt plug-in heater is not enough and a 240-volt hardwired unit like the Comfort Zone or VEVOR garage heaters is the more realistic option.

What is the difference between a ceramic and an infrared space heater?

A ceramic heater, like the DREO, PELONIS tower, Lasko, Amazon Basics and GiveBest picks in this guide, heats a ceramic plate and uses a fan to blow that warm air into the room, which is why it stops producing heat instantly once the fan is off. An infrared heater, like the Dr Infrared Heater DR-968 and the BLACK+DECKER quartz tower, uses radiant heat to warm people and objects directly rather than only the surrounding air, so it can feel warm at close range even before the room itself has fully heated up.

Do garage heaters need to be professionally installed?

Heaters rated above roughly 5000W, like the Comfort Zone 7500W and VEVOR 5000W picks in this guide, run on a 240-volt circuit and must be hardwired into your electrical panel by a licensed electrician rather than plugged into a standard outlet. Every other heater in this guide is a standard 120-volt plug-in unit that requires no installation and can be moved between rooms freely.

How much does it cost to run a 1500W space heater?

Running cost depends on your local electricity rate and how much of the time the thermostat is actively heating rather than idle, since most heaters cycle on and off once a room reaches its target temperature rather than running at full power continuously. A heater with a precise digital thermostat, like the DREO or PELONIS tower in this guide, generally runs more efficiently than a basic low-high dial heater because it stops heating as soon as the target temperature is reached instead of overshooting. Check your utility bill for the exact per-kilowatt-hour rate in your area rather than relying on a single national average, since rates vary significantly by region and season.

Buying guideHow to choose

Ceramic vs infrared vs oil-filled radiator heating

Ceramic heaters, like the DREO, PELONIS tower, Lasko, Amazon Basics and GiveBest picks in this guide, heat a ceramic plate and use a fan to push warm air into the room, which heats up fast but stops producing warmth the moment the fan is off. Infrared heaters, like the Dr Infrared Heater DR-968 and the BLACK+DECKER quartz tower, warm people and objects directly with radiant heat rather than only the air, so you feel warmth quickly even before the room air has fully risen in temperature. Oil-filled radiators, like the PELONIS radiator heater, warm oil sealed inside metal fins that keeps releasing heat even after the thermostat cycles the element off, which makes them a common choice for overnight use in nurseries or kids rooms since there is no exposed glowing element to touch.

Matching wattage and coverage to your room size

Most 1500W plug-in heaters, which is the standard maximum output for a 120-volt household outlet, are rated for somewhere between 150 and 300 square feet depending on the design, with the compact Amazon Basics and GiveBest picks suited to a single small room and the PELONIS 30-inch tower stretching closer to 280 square feet with oscillation. If you need to heat an entire garage, workshop or multi-car bay, a 120-volt plug-in heater simply cannot deliver enough output, which is why the Comfort Zone and VEVOR 240-volt hardwired units exist as a separate category rated for 500 to over 1200 square feet.

Plug-in room heaters vs hardwired 240V garage heaters

Every heater in this guide except the Comfort Zone and VEVOR units plugs directly into a standard household outlet and can be moved from room to room with no installation required. The Comfort Zone and VEVOR garage heaters run on a 240-volt circuit and must be hardwired into your electrical system by a licensed electrician, which is a bigger upfront project but delivers far more heat output than any plug-in unit and is designed to be mounted permanently overhead or on a wall out of the way of vehicles and equipment.

Safety features that matter most

Tip-over protection, which cuts power automatically if a heater is knocked over, and overheat protection, which shuts the unit down if internal temperatures climb too high, are the two safety features every heater in this guide includes at minimum, and neither should be skipped when shopping outside this list. For nurseries, kids rooms or any space where a heater will run unattended overnight, an oil-filled radiator like the PELONIS pick is worth extra consideration since it has no exposed glowing element for curious hands to touch. Always plug a space heater directly into a wall outlet rather than an extension cord or power strip, since the sustained current draw can overheat lower-rated cords.

At a glanceFeatures compared

FeatureWhy it matters
Heating method: ceramic, infrared or oil-filledCeramic heats fast with a fan, infrared warms people and objects directly, and oil-filled radiators keep radiating heat after the element cycles off.
Coverage area ratingMatch the manufacturer square-footage rating to your actual room size rather than assuming every 1500W heater covers the same area.
Tip-over and overheat protectionBoth should be standard on any heater you buy; they cut power automatically if the unit is knocked over or runs too hot.
Oscillation and thermostat precisionOscillating towers spread heat across a room instead of one direction, and a precise digital thermostat holds temperature steadier than a basic low-high dial.
Plug-in 120V vs hardwired 240VStandard heaters plug into any household outlet, while garage and workshop units above about 5000W require a hardwired 240V circuit installed by an electrician.
