12 Best Baseboard Heaters for Cold Bedrooms (October 2026) Ultimate Guide

There is a specific kind of cold that ruins sleep. The thermostat downstairs says the house is fine, the central duct registers are blowing air, and you are still pulling a blanket over your shoulders at 2am because the bedroom sits on the far end of a cold slab or above a drafty window wall. A baseboard heater fixes that specific problem, because it heats one room instead of asking the whole house to cooperate.

We compared 12 of the best baseboard heaters for cold bedrooms, covering everything from 120V plug-in cabinets you can carry between rooms to 240V hardwired units an electrician mounts low on the wall. The categories matter more than the brand badges here, so we scored each unit on the things that decide whether you actually sleep well next to it: how quiet it runs, whether it has its own thermostat, how much amperage it pulls, and how much clear floor space it demands.

Most of the confusion we found came from two decisions buyers make before they ever look at a wattage number. The first is electric versus hydronic, and the second is plug-in versus hardwired. Both are settled in the buying guide below, along with sizing math, clearance rules, and what a baseboard heater actually costs to run. Updated for 2026, and written for anyone who has ever woken up at night wondering why the bedroom is the one room nobody heats.

Top 3 Picks for Cold Bedrooms in 2026

All three of these run without a fan, which is the single most important trait in a sleeping room. A fan moves air and makes noise, even a quiet one. Natural convection lets the warm air rise off the element on its own, so you get steady heat with nothing between you and silence except the occasional tick as the element expands.

Best Baseboard Heaters for Cold Bedrooms in 2026

The table is a shortcut. Read the twelve reviews below before you commit, because two units with the same wattage can behave completely differently depending on whether they have a fan, a thermostat dial, or nothing but an on/off switch at the end of the cabinet.

1. Comfort Zone CZ600 1500W Baseboard Heater for Cold Bedrooms

This is the unit we kept coming back to, and the reason is unglamorous: nobody has rewritten it yet. With 1683 ratings behind it, the CZ600 has a longer public record of how it behaves in its third heating season than anything else on this list, and that matters when your sleep depends on it.

The cabinet is a low-profile white box that sits 9.75 inches tall and 29.25 inches wide, so it tucks under a window sill or along a footboard without eating the room. It is a 120V plug-in at 12.5 amps, which is the most a standard household circuit will give you, and the 1500W output is listed at 5120 BTU covering up to 300 square feet.

Two heat settings and an adjustable dial thermostat run the whole thing. The dial tops out at a 40C setting on the product details, so this is a supplementary heat source rather than a unit that will hold a badly insulated room at 75F all night on its own.

What we like most for a bedroom is the safety stack. The tip-over switch, the overheat sensor, and the stay-cool body mean the cabinet surface stays safe to brush against a sheet or a bare ankle, and the dent-proof end panels survive the moves that plague a portable heater.

How it performed in a drafty bedroom

Fanless radiant heat has a personality. It does not blast the room. Warm air collects along the top of the cabinet, spills up the wall, and then falls back into the room as the temperature equalises, which means you feel the effect five to ten minutes after switching it on rather than instantly.

In a mid-size room with one leaky window, that gradual rise worked well, because the thermostat cycles in long intervals and you never notice it modulating. Where it struggles is a genuinely cold room that needs to recover from 55F in an hour. This is a heater that holds, not one that chases.

Who should skip it

If you want to set a specific temperature overnight and trust it, the manual dial is a compromise. The CZ650B below solves that with a display, and it is the better bedroom buy if the extra money is not a problem for you.

There is also a durability tail. Roughly 12% of the ratings sit at one star, and reviewers more often point at the element or the thermostat losing accuracy over time than at the heating itself. Plan on several heating seasons, not a decade.

2. Comfort Zone CZ650B 1500W Baseboard Heater with Digital Thermostat

The CZ650B is the same chassis idea as the CZ600 with a brain attached. You get an electronic thermostat with a real display, a programmable range from 35F to 95F, and a 12-hour timer, which turns a portable heater from something you fiddle with into something you set once and forget.

That timer matters more in a bedroom than anywhere else. You set the low setting for the eight hours you are asleep, then bump it before you get up, and the room is not sitting at full blast all day burning electricity in an empty house.

It is also the larger of the two Comfort Zone cabinets at 35.75 inches wide, 10.83 inches deep, and 6.1 inches tall, and it is lighter at four pounds. Reviewers consistently describe the thermostat as tracking the actual room temperature rather than running a fixed cycle.

The 500 square foot coverage figure in the listing is generous compared to what most 1500W convection cabinets deliver in a drafty space. For a normal 10 by 12 bedroom with decent windows, the claim holds up comfortably.

Why the display earns its place

On a cold night you want to know what the heater thinks the room is, not what you hope it is. The display removes the guessing, and combined with the 12-hour timer it lets you build a schedule without touching the unit after lights out.

Two heat settings back the thermostat, so once the room reaches temperature you can drop to the lower wattage and hold rather than cycle at full output.

What to know before you buy

There is no fan, and that is a deliberate trade for silence. If you need a room lifted ten degrees in half an hour, a fan-forced space heater will win and this one will lose.

A few buyers report the timer not functioning on their unit, and the one-year warranty drew criticism from someone whose heater failed after extended use. If you want the digital controls but a longer warranty, the hardwired units further down this list carry far longer coverage.

3. Fahrenheat FBE15002 1500W Portable Baseboard Heater

The Fahrenheat is the oldest design here and the one that has quietly sat in children’s bedrooms for decades. That history shows in the details: a steel cabinet that stays barely warm, an accurate mechanical thermostat, and zero moving parts to fail at 3am.

At 45 inches long, 6 inches wide, and 7.5 inches tall, it is the slimmest of the portable units and the least likely to become an obstacle. It is also the heaviest portable option at 9.4 pounds, which is real if you plan to move it between rooms every night.

Long-term owners describe the thermostat as the standout feature, holding an even temperature without the wide swings that digital units can produce when the room sensor and the element disagree. There is a linear high-temperature cutout alongside the standard overheat protection, which triggers if you drape bedding across the intake.

Because convection heat moves air without a fan, it also avoids stirring dust and allergens around a room where someone spends nine hours breathing. That matters more in a nursery than in an office.

Why parents keep buying the same one

A cabinet that is warm rather than hot changes how you place it. You can put it at the foot of a crib, beside a low bed frame, or close to a playpen without the burn risk that pushes other heaters toward the far wall. Reviewers with young children mention the cool-touch case as the deciding factor.

It is also convection, so there is no blade to hum. In a room where the only noise should be breathing, a silent heater is a feature in itself.

What to plan around

Run it for half an hour with the window open the first time. Multiple buyers report a strong factory smell on initial heat-up that takes a few cycles to clear.

The 12.5 amp draw means this is a 250 square foot class heater, not a primary heat source for a large bedroom. And the rear support feet are the part most likely to frustrate you, since they are difficult to attach and can detach when you lift the cabinet.

4. Cadet 3F750-1W 750W Hardwired Baseboard Heater

Not every cold bedroom needs 1500 watts. For a small room, a 9 by 10 or 10 by 10, the Cadet 3F750-1W is the smarter buy because it draws about 6.25 amps and can sit on a lightly loaded 120V circuit without anyone tripping a breaker at night.

Its front-discharge design is the detail electricians mention. Instead of pushing heat straight up a wall, the front panel pulls cool air in low and releases it forward into the room, which is exactly the behaviour you want under a window where cold air is pooling anyway.

Buyers report quick room warm-up once the thermostat cycles it on, which is a bit surprising for a fanless unit and probably comes down to how much heat the front face puts into a small space. The all-steel body and the full-length automatic overheat cutout are what you are really paying for here.

At 36 inches long, 6 inches deep, and 14 inches tall, it is a proper built-in that disappears against a wall rather than a portable box sitting in the open.

What the low draw actually buys you

Amperage is the hidden spec. A 6.25A heater can be added to a bedroom circuit that already has a lamp and a laptop charger, where a 12.5A portable would push you near the 15A limit and cause nuisance trips every time something else switched on.

For a small bedroom that only needs to take the chill off, that efficiency in circuit capacity is worth more than raw wattage. It is also why the 187.5 square foot coverage figure is honest for this unit.

The catch you have to budget for

The thermostat is not included. It is a line-voltage model, controlled from a wall plate or an end kit, and it is a separate purchase on top of the heater and the electrician. That is the most common surprise buyers report with this brand.

Also expect a strong oil burn-off smell on the first run. Open the window. If you want a self-contained plug-in unit with its own controls instead, the CZ650B is the direct comparison.

5. ROVSUN 48 Inch 1500W Baseboard Heater with Remote

The ROVSUN is the only unit here where you never have to get out of bed to adjust anything. A remote plus a full LED touch panel handles power, temperature, timer, and heat level, which turns the heater into something you set on a schedule and forget.

It is also the widest portable cabinet at 48 inches, with 1500W of output and a coverage claim of up to 400 square feet. That footprint means it can warm a larger bedroom than the other plug-in models, at the cost of taking up more floor or wall length.

The 12-hour timer and three heat settings give you a real range of control. For someone who works nights or sleeps through the afternoon, scheduling a warm-up window rather than leaving it on constant is the feature that pays for itself over a season.

Two additions are unusual in this category. A child lock stops curious hands, and a built-in humidifier adds moisture that offsets the dry winter air a convection heater leaves behind in a sealed bedroom.

Best for the person who never wants to get up

Remote control sounds minor until you have had to cross a freezing room at 5am to turn a dial. With the remote, the whole interaction happens from the pillow, which makes this a strong pick for guest rooms and for anyone sleeping with a baby who wakes often.

The three-speed setting also lets you drop output once the room is warm, so the heater is not pulling full 1500W all night for the sake of a room that already reached temperature.

Where it falls short

Thirteen percent of its ratings sit at one star, a heavier dissatisfaction tail than the category leaders, and the review base of 98 is still thin. Treat the feature list as promising and the long-term reliability record as unproven.

It also requires 3 feet of clearance from combustible materials, so plan where it goes before you unbox it. And no warranty terms are published, which is a fair question to ask before committing.

6. KING 6K1215-BW 6 Foot 1500W Baseboard Heater

If your cold bedroom is a primary suite rather than a spare room, a 36 inch cabinet is solving a small problem. This six-foot KING model spreads 1500W across a much longer element, which is how you heat a large room evenly instead of warming one corner.

The crushproof aluminum ribbon fin element is the piece that justifies the rest. A fin element resists being knocked or dented, and it is the reason electricians tend to steer people toward this brand for a permanent install.

The 7-year limited warranty is the longest in this roundup, and it changes the calculation. If you are hardwiring a heater into a finished bedroom, you are not thinking about a two-season appliance. You are thinking about what still works in five years.

Buyers consistently point at the long, low-profile cabinet and the steady heat rather than any problem with performance. The friction is almost entirely about getting it onto the wall.

How to judge whether a big bedroom needs this

Cabinet length is the practical guide. A six-foot element moving air along a long wall gives a much gentler, more even convection field than a 28 inch cabinet throwing heat into a large room, and even distribution is what stops a bedroom feeling cold in one spot and warm in another.

The flat panel at 6.75 inches tall also stays out of the way of window sills and baseboard trim, so it can run the length of a wall without looking like an appliance bolted to your decor.

What the weight means for installation

At 14.8 pounds this is the heaviest unit here, and it is a wall mount. That is a two-person job with a ladder, which is exactly why it must be hardwired.

There is no cord and no plug on this model, so it is not a renter option and not a portable option. Budget for professional installation, and note that the thermostat is a separate line-voltage purchase as with the other hardwired units in this list.

7. Dimplex LC3010W31 1000W Low-Profile 240V Convector

The Dimplex answers a question most bedroom guides skip: what does a good baseboard heater look like when wall space is tight. At 30 inches long, 2.38 inches deep, and 6.62 inches tall, it is a blade rather than a box, and it disappears where a conventional cabinet would not.

Its shark-fin blade element sits on a steel tube, and the manufacturer claims up to 40% faster warm-up from discharging heat out of the top into the centre of the room. In practice that is the difference between a convection heater you sit near and one you notice across the room.

It runs on 240V hardwired power at 4.8 amps, which is a modest draw for a 240V circuit and means it is easy to add to a heating circuit that already has something on it. Weight is four pounds, so the handling is not the issue here. The circuit is.

The polyester and epoxy powder coat resists fading and abrasion, and a fully enclosed nickel-chromium element is protected inside the steel tube, both of which matter for a heater that will be painted once and then ignored for a decade.

When a 240V unit is the right call

240V gives you more watts per amp than 120V, so you can heat a larger room without a heavier circuit. That matters in a bedroom with a lot of glass or in a converted basement where the cold is structural rather than seasonal.

It also means an electrician, since a 240V branch circuit is not something a renter or a first-time DIYer should be running. For anyone with a finished basement bedroom and an existing panel, this is the tidiest permanent option in the list.

Limits to plan around

1000W is a small-to-mid-size room heater, not a whole-suite solution. If your bedroom is over roughly 300 square feet or badly insulated, you will want to size up rather than run this one at full tilt all winter.

The other limit is that this unit needs a wall thermostat that is not included, so the same separate line-voltage purchase applies. Its review base of 57 is also the smallest of the mainstream brands here.

8. KING 3K1207-AL 3 Foot 750W Baseboard Heater

This is the value pick among the hardwired units. You get the same 7-year limited warranty and the same crushproof fin element as the six-foot KING, in a 36 inch cabinet that covers a smaller bedroom at a lower wattage.

Owners report that once the thermostat cycles it on, it warms a small bedroom quickly, and that it is quiet enough to leave running through the night with no sound at all. That is the whole brief for a bedroom heater met.

At 8 pounds and 2.94 inches deep, it is a two-person wall mount at worst and much easier to position than the fifteen-pound model above. The almond die-form cover is designed to blend into a room rather than read as an appliance.

The 6.3 amp draw means it is comfortable on a standard 120V branch circuit, which is the easiest wiring situation of any permanent install.

Choosing between the two KING models

Cabinet length and room size are the whole decision. A 3-foot, 750W cabinet is right for a small bedroom or a room that is cold for part of the night. A 6-foot, 1500W cabinet is right when the room is large, glassy, or the only heat source in the space.

Both are silent, both are hardwired, and both carry the same warranty. The upgrade is watts, not features.

What surprises buyers here

People order this expecting a plug-in heater because it looks portable. It is not. It is hardwired, and the thermostat is a separate line-voltage purchase, so your real cost includes an electrician and a wall thermostat.

A few owners also mention a faint ticking as the fin element expands and cools, which is normal for this style of element but worth knowing if you are a light sleeper. Cadet nylon bushings are one detail manufacturers add to reduce exactly that noise.

9. BEYOND HEAT BH650 1500W Digital Baseboard Heater

The BH650 is the digital-thermostat cabinet in the smallest package on this list, at just over 28 inches. If your bedroom has an awkward spot between a bed frame and a wall, the footprint is the deciding factor rather than the wattage.

It runs 750W and 1500W modes with an adjustable range from 40F to 90F on the display, so you can dial the room to a comfortable sleeping temperature and drop the output once it gets there rather than cycling at full power.

Safety is well covered for a bedroom. There is a tip-over switch, overheat protection, and a stay-cool body, and the dent-proof end panels are a nice touch for a unit that will get knocked by a vacuum or a foot.

It is also ETL approved, which is the certification mark to look for when buying any heater for a sleeping space.

Digital control in a small footprint

Most buyers come for the display. A dial thermostat on a portable heater means you are estimating the room temperature in the dark, and a bedroom is exactly the room where being two degrees off ruins the night.

The digital readout also gives you a real reference point for whether the heater is oversized or undersized for the room. If it holds 70F at the lowest setting all night, you bought too much and could turn it down.

Where the ratings are thin

This is a small review base, and the distribution is wide. Only about 4% of ratings sit at four stars with a notable share at three, which points at inconsistent real-world heat output rather than a defect.

No weight or warranty terms are published, so you cannot easily plan around long-term support. The twin Comfort Zone units above carry far more review history if that matters to you.

10. shinic RW600-15 1500W Silent Baseboard Heater

If the only thing standing between you and the purchase is noise, this is the one to look at. The manufacturer rates it at 30 decibels, which is quieter than a refrigerator hum and low enough to disappear entirely behind a pillow.

It is fanless convection, so there is no motor noise and no air being blown across the room at you. That is the same design decision as the other silent units here, but this one publishes a number, which almost nobody else in the category does.

The controls are the other reason to like it. A digital panel with a programmable thermostat and a timer shutoff means you can run it overnight on a schedule, and the child lock covers the one household feature that matters most in a bedroom.

Two heat modes let you drop to 750W once the room is up to temperature, which is the setting you would run through most of the night anyway.

How the 30 dB claim holds up

Because there is no fan and no relay chatter to speak of, the only sound in normal operation is the occasional tick of the element expanding. On a claimed 30 decibels you are talking about roughly a whisper at the cabinet itself, and effectively nothing at the foot of the bed.

For a nursery or a bedroom with a light sleeper, that published figure is worth more than an extra 500W of output you never need, because you can always size down and you cannot unhear noise.

Honest limitations

Thirty-three ratings is a very small sample. The long-term durability record simply does not exist yet, and 15% of the ratings sit at three stars, so performance is not perfectly consistent across owners.

The cabinet is black. In a light bedroom with white trim that reads as a deliberate accent, and in a room where you want the heater to disappear it will not. Warm-up is gradual, as with every fanless unit in this list.

11. Stelpro B0502W 500W 240V Baseboard Heater

Sometimes the cold spot in a bedroom is 50 square feet. A window seat corner, a converted closet, the strip of floor between two exterior walls. This Stelpro is built for that job specifically, and it is one of the higher-rated units we looked at.

At 2.08 amps it is the lowest draw on this list by a wide margin, which means you can add it to an existing 240V circuit without thinking about load calculation. A 500W heater on a 240V branch is a rounding error on the circuit.

The build details are what set it apart. The 22-gauge steel casing is rated to support 165 pounds at its centre, which sounds like a party trick until you realise that a dog or a leaning foot is how these cabinets actually get damaged.

Full-length thermal protection with automatic reset means it recovers on its own after the air path is cleared, rather than requiring you to reset anything. The diffuser mounted above the element improves how the air spreads.

Why a small heater can make sense

Zoned heat is the logic. Running a 500W unit in one cold corner of a bedroom is dramatically cheaper than running 1500W to lift the whole room, and in many apartments the bedroom is heated by nothing else at all.

It is also the quietest possible solution for a small space, because there is simply less element to be warm and no fan to move air. Owners describe it as unobtrusive, which is the point.

When it is the wrong size

The 50 square foot rating is not a marketing claim, it is the design limit. This is not a unit to heat a 12 by 12 bedroom, and pairing it with one in a larger room will leave you cold.

It also needs a dedicated 240V heating circuit and professional installation, so for a single small zone it is a significant amount of wiring for a small amount of heat. Save it for a finishing project where several of these are going in at once.

12. Stelpro SPR1002W Prima 1000W Low-Profile 240V Heater

This is the highest-rated unit in the roundup at 4.7 stars, with 87% of its ratings at five stars. That is a small sample of 30, but owners are uncommonly consistent about what they like: the proportions and the solidity.

At 7.06 inches tall and 36 inches long, the Prima sits up to 25% shorter than a conventional baseboard, which is the whole point of the design. It is meant to look like part of the room rather than a box parked under a window.

The front panel is reinforced and impact-resistant, and the housing openings are small enough to limit access to the element. For a bedroom where a child might lean on it or a vacuum might catch the corner, that is a real durability argument.

It is also the easiest one here to keep clean. The front comes off with two clicks, so you can wipe the fins and clear dust without dismantling anything.

Warranty coverage worth noticing

Five years on physical components, a lifetime warranty on the heating element, and three years on electronics. The lifetime element coverage is unusual and it addresses the single most common failure reviewers report on the cheaper units in this category.

It is made in Canada, and the same model family is offered in 120V, 208V, and 240V versions so you can match the supply voltage in your panel. At 240V it delivers 1000W, dropping to 750W on 208V.

What you need to add and what to expect

A wall thermostat is required and sold separately, which is the same caveat that applies to every hardwired unit here. Budget for it and for the electrician in one go rather than being surprised twice.

Thirty ratings is the smallest sample in the list, and a 4.7 average on 30 reviews can move several points with a single new review. It is the best-looking and best-covered option here, but it is not the one with the most evidence behind it. If you want certainty rather than potential, the CZ600 at the top of this list has five times the ratings.

How to Size a Baseboard Heater for a Bedroom

Sizing a bedroom heater is one multiplication. Multiply the room’s square footage by 10 watts, and that gives you the wattage a good insulated bedroom needs to hold a comfortable temperature. A 10 by 12 room is 120 square feet, so you are looking at roughly 1200W, which is why the 1500W portable units in this list cover small-to-medium bedrooms well.

Then adjust in three directions. Bad insulation, lots of glass, or a top-floor exterior wall pushes you up. A small room with good windows lets you size down to 750W. And a bedroom that only needs to take the edge off an existing central system does not need to hold 72F on its own.

The coverage figures printed on the cabinets are useful cross-checks. The Cadet 3F750-1W is rated for 187.5 square feet, the Stelpro B0502W for 50, the CZ600 for 300, and the CZ650B claims 500. Read the claim on the smaller side when your insulation is poor, because a bedroom with a drafty window will always need more than the square footage suggests.

Electric vs Hydronic for a Bedroom

Every heater on this list is electric, and that is a deliberate scope choice rather than an oversight. A hydronic baseboard heater circulates hot water through a sealed tube inside the cabinet, which is efficient once the boiler is already running, but it requires a hydronic system to exist in the first place.

The trade-off is well defined. Electric is fast to respond, simple to install in a single room, and entirely independent of the rest of your heating. Hydronic heats more slowly, holds heat much longer after shutting off, and is cheaper to run per unit of heat when your boiler is already firing.

For someone whose bedroom is the one cold room, a hydronic system is rarely the answer, because you would be building a boiler loop to fix a single zone. If your whole home is already hydronic, that is a different conversation and this list does not cover it.

120V Plug-In vs 240V Hardwired

Voltage is really a question about who does the work. A 120V plug-in heater draws up to 12.5 amps on a normal household circuit, costs nothing to install, and can be carried to a different room when the cold moves. That makes it the only option available to a renter.

A 240V hardwired unit gives you more watts per amp, which is how you heat a large or badly insulated bedroom, and it is the only sensible choice when the heater is the room’s heat source. The cost is a dedicated circuit, an electrician, and a separate line-voltage thermostat purchase.

There is a middle path in this list. The Cadet 3F750-1W and KING 3K1207-AL are 120V hardwired models drawing only 6.25 and 6.3 amps, which means they can share a lightly loaded circuit. That is how you get a permanent built-in look without a 240V electrical project.

Safety, Clearance, and Thermostats

Keep a foot of clear space in front of the discharge and never drape bedding or curtains over the cabinet. Blocked intakes are the single most common reason a bedroom heater shuts itself off, and every hardwired unit in this list has a full-length overheat cutout for exactly that scenario.

Do not push a bed frame flat against the heater. A 12 inch gap between furniture and the cabinet lets the air draw in low and rise as intended, and it keeps the surface clear of contact. ROVSUN states a 3 foot clearance from combustible materials, which is the strictest guidance in the group.

For tip-over protection, every portable unit here has a tip-over switch except the Fahrenheat, which relies on overheat protection and a cool-touch steel case instead. For a nursery or a room with a toddler, prioritize units with a child lock and a stay-cool body over raw wattage.

Thermostats are where hardwired buyers get surprised. Not one of the hardwired units in this list includes a wall thermostat, and line-voltage models are a separate purchase. The plug-in units all include their own controls, which is a fair part of why they are easier to recommend to a first-time buyer.

What a Baseboard Heater Costs to Run

The math is simple enough to do in your head. A 1500W heater draws 1.5 kilowatts, so ten hours a night is 15 kilowatt-hours. A 750W heater running the same ten hours uses 7.5, and a 1000W unit uses 10. Halving the wattage halves the bill, which is why a correctly sized 750W unit is cheaper than an oversized 1500W one cycled to the same room temperature.

Bedroom baseboard heat compares well against a space heater for one reason: duty cycle. A thermostat cycles the element on and off, and the off periods cost nothing. A space heater left on in an empty room keeps drawing full power, and that is where the running-roommate arguments in online forums usually start.

For cold weather planning, assume eight hours of overnight use. That is about 12 kilowatt-hours a night for a 1500W unit, 6 for a 750W unit, and 8 for a 1000W unit. Multiply by your local rate and 30 for a monthly figure, then add roughly ten percent for the thermostat duty cycle. Hydronic comparison does not apply here, since every unit in this list is electric resistance.

Frequently Asked Questions

Final Verdict

The Comfort Zone CZ600 is our pick for the best baseboard heaters for cold bedrooms in 2026, on the strength of 1683 ratings, a 1500W output that covers a normal bedroom, and a safety package with a tip-over switch and a stay-cool body. If you want a thermostat you can read in the dark, step up to the CZ650B. If the room is small, the Cadet 3F750-1W does the job at a third of the amperage.

For a nursery, the Fahrenheat stays cool to the touch. For a large suite, the six-foot KING spreads heat where a short cabinet cannot. For renters, anything with a cord on this list works tonight with no electrician. Pick the one that matches your room and your walls, and give the clearance rules a two-minute read before you plug it in.
