Best Heaters for Cold Rooms with Wood Floors

Updated 28 min read
Quick answer
For most cold rooms with wood floors, the Dr Infrared Heater DR-968 gives the best mix of floor-safe infrared warmth, quiet fan assistance and whole-room coverage. It heats people and surfaces directly while circulating air, so your feet and floor warm up instead of just the air at head height.

Wood floors over a garage, crawlspace or slab can leave a room feeling cold long after the thermostat says it is warm. Standard fan heaters often blast hot air at your face while the floor and your feet stay icy.

The right heater type, size and placement can warm the room and the floor surface without risking scorch marks, dried-out boards or sky-high bills. The picks below are chosen with wood-floor safety, room coverage and noise in mind.

Best Heaters for Cold Rooms With Wood Floors

Wood floors make a cold room feel harsher because they pull heat from your feet and ankles. For a heater for a cold room like that, the best solution for cold wooden floors is a unit that warms the floor surface and your body, not just the air up at head height; people type “heater lantai codl room” after padding across icy boards in the morning.

Wood transfers heat faster than carpet, and there is no padded layer of air-trapping fibers, so bare boards always feel like cold floors. Rooms over an unheated basement or a concrete slab stay colder still, because the structure under the boards acts as a heat sink. Warm air from any heater rises and stratifies, so it can be 70°F at eye level and closer to 60°F down at the floor, which is why your feet can ache while your face feels fine.

Wattage alone will not fix a cold wood floor
Most plug-in space heaters in the U.S. top out around 1,500 W. Comfort differences on wood floors come mainly from heater type, airflow pattern, thermostat control and placement, not from buying an even bigger wattage on the same outlet.
Heater TypeFloor Comfort on WoodNoise LevelBest Use Cases
Infrared cabinet (e.g. Dr Infrared Heater DR-968, 1500W infrared cabinet heater)Warms people and floor surfaces directly; good for rooms where air never feels evenly warmModerate fan noiseLarge wood-floor living rooms, open-plan spaces, very cold spots
Tower PTC ceramic heater (e.g. Mountman 37″ Space Heaters for Indoor Use)Fast warm air that mixes the room; helps reduce cold layer at floor if pointed along the floorNoticeable fan noiseLiving rooms, home offices, hallways where you want quick heat
Compact ceramic heater (e.g. R.W.FLAME Small Space Heaters, 1500W Ceramic)Strong local warmth for feet and one area of floor, but limited reachNoticeable to loud fan noise at higher settingsHome offices under a desk, small bedrooms, laundry corners
Oil-filled radiatorSlow, even warmth that gently raises whole-room and floor temperatureVery quiet (no fan); faint clicking as it cyclesBedrooms, nurseries, any room needing all-night heat on wood floors
How common heater types feel and sound on cold wood floors.

Infrared cabinet heaters such as the Dr Infrared Heater DR-968 and the Electric Space Heater for Indoor Use 1500W Infrared Heater focus their energy on people and nearby surfaces, so wood planks, rugs and furniture all warm up. Their enclosed elements and cabinet-style cases are well suited to wood floors, and the built-in fan is usually quieter than a typical ceramic blower while still circulating air so the cold layer near the floor gets mixed. This style is a strong choice for a cold wood-floor living room or den that you use for hours at a time.

Tower PTC ceramic heaters, like the Mountman 37″ Space Heaters for Indoor Use, push a tall column of warm air that can quickly take the chill off a wood-floor space. Many tower heaters include oscillation, which helps spread heat along the floor; check that feature if you plan to use one in a long room or hallway. The tradeoff is fan noise: you will hear airflow in a quiet house, so they suit busy living areas, hallways and laundry rooms more than light sleepers.

Compact ceramic heaters such as the R.W.FLAME Small Space Heaters for Indoor Use and the R.W.FLAME Small Space Heater for office,1500W Ceramic Heate… concentrate heat in a short throw. On wood floors they excel as personal heaters: slide one near your desk to warm your feet and the boards under your chair, or use one in a very small bedroom where you want fast spot heat before bed. Because the fan and outlet are close to you, ceramic cubes can sound quite loud on high, so keep them on lower settings for work calls or study.

Oil-filled radiators have sealed heating elements inside a metal body filled with oil, so every surface that touches your wood floor is solid metal at a stable temperature. They take longer to warm up but then radiate and convect gentle heat that slowly lifts the temperature of the air and the floor across the room. With no fan, they are the quietest option for sleep, making an oil-filled radiator a top pick for wood-floor bedrooms; our best oil filled radiator guide walks through specific models.

  • Large wood-floor living rooms: An infrared cabinet like the Dr Infrared Heater DR-968 gives strong, even warmth without roasting the nearest chair legs.
  • Small bedrooms with wood floors: An oil-filled radiator or an infrared cabinet on a low thermostat setting keeps floors from feeling icy all night.
  • Home offices on wood floors: A compact R.W.FLAME ceramic heater aimed at your legs and floor fixes cold feet without overheating the whole room.
  • Hallways and laundry rooms on wood: A slim tower PTC ceramic heater is easier to tuck out of the way while still pushing warm air along the floor.
Skip exposed-coil heaters on wood floors
Older radiant heaters with glowing bars or visible coils can run extremely hot at the point of contact, so if they tip onto a wood floor or sit too close to dust, rugs or baseboards they raise a real fire and scorch risk. For wood floors, choose heaters with enclosed elements, a stable base, a working tip-over switch, overheat protection and a UL, ETL or CSA safety listing, and plug them directly into a wall outlet.

Fan noise is not negligible. PTC ceramic heaters, both tower and compact, always use a fan, and the rush of air is obvious in a quiet room, especially on high. Infrared cabinet heaters like the DR-968 use a gentler fan that most people tolerate in living areas but may still notice at night. Oil-filled radiators are effectively silent except for the occasional tick, which is why they are usually the best heater choice for light sleepers on wood floors.

Do not expect a bigger-wattage label alone to cure freezing boards over a crawlspace or slab. If a 1,500 W heater already struggles, a second heater will make the air hotter at head height while the floor still bleeds heat and your power bill climbs. Sealing drafts, improving insulation and dealing with rising cold under the floor often matter more than upgrading the heater, and guides like our best heaters for cold floors rising drafts are built around that problem.

Sizing Heat Output and Running Cost for Wood Floors

A heater for a cold room with wood floors needs enough wattage for the space, but more power alone does not fix a drafty, poorly insulated room. Think first about room size and how leaky it is, then match the heater to that job.

How Many Watts You Really Need

Room typeTypical sizeHeater output that makes sense
Small bedroom or office80–150 sq ftUp to 1,500 W plug-in heater
Medium bedroom / small living room150–250 sq ftOne 1,500 W heater, good insulation needed
Large living room or open plan250+ sq ftTwo 1,500 W heaters or upgrade main heating
Hallway or landing< 100 sq ftLow or medium setting on a 1,500 W heater
Match heater output to how much space you actually heat, not the whole house.

Most U.S. plug-in space heaters top out around 1,500 W. One 1,500 W unit is usually enough for a small or medium room with wood floors if you close doors and cut drafts. Large living rooms often need two heaters or a stronger central system, especially best heaters for a cold living room with big windows and high ceilings.

A cold room coil heater rated at 1,500 W does not make more useful heat than a 1,500 W PTC ceramic or infrared heater. They all turn 1,500 W of electricity into the same amount of heat; the coil style just runs hotter at the element and is less friendly to wood floors and nearby rugs.

Watts vs BTU
If a heater lists BTU instead of watts, divide BTU by about 3.41 to get watts. A 5,100 BTU heater is roughly 1,500 W, which is the practical limit for a standard 120 V wall outlet.

Why Thermostats and ECO Modes Save More Than Lower Wattage

What matters on your bill is how many hours the heater actually draws full power over the day. A 1,500 W unit with a good thermostat or ECO mode, like the Mountman 37″ heater or the R.W.FLAME small heater, often runs at full blast for a short time, then cycles off or down to maintain temperature.

Running a 1,500 W heater on high until the room is warm, then letting the thermostat cycle it, usually uses less energy than locking a 1,000 W heater on constantly because it never quite catches up. A smart thermostat also helps avoid overheating the room and drying out your wood floor, so it is a better upgrade than simply choosing a lower-wattage model best electric heaters with thermostats.

What It Costs to Run a Heater vs a Heated Blanket

The basic cost formula is simple: watts ÷ 1,000 × hours × electricity rate. If your utility charges about $0.17 per kWh, a 1,500 W heater for eight hours costs 1.5 × 8 × 0.17. A 100 W heated blanket over the same time is 0.1 × 8 × 0.17.

ApplianceWattsPer hourPer day (8 h)Per month (30 days)
1,500 W space heater1,500 W26¢$2.04$61.20
Heated blanket100 W1.7¢14¢$4.08
Calculated at 17¢ per kWh. Monthly cost if you run each option 8 hours per day at $0.17/kWh.

Use a room heater to bring the wood floor and air to a comfortable range, then rely on a heated blanket, heated mattress pad, or heated throw to keep your body warm in place. That mix cuts run time on the big heater, which is where most of the cost sits.

Heaters and Power Cuts in Cold Rooms

All plug-in electric room heaters stop working in an outage, no matter if they are ceramic, infrared or oil-filled. Room heaters for power cuts have to burn fuel, like propane or kerosene, or connect to a generator with enough capacity.

Fuel heaters indoors
Only use a fuel-burning heater that is clearly rated for indoor use, follow its ventilation instructions and keep a working carbon monoxide alarm in the room. Never bring an outdoor or construction heater inside; carbon monoxide buildup and fire risk are real dangers on wood floors and in tight rooms.

If outages are common in a house with cold wood floors, plan for insulation, draft sealing and a safe backup heat source rather than counting on an electric space heater best heaters for cold ground floor rooms.

Cut Heat Loss First, Then Size the Heater

A space heater has to replace whatever heat your room leaks, so fixing leaks can let a single 1,500 W unit do work that used to take two. Closing doors, adding a door sweep, and sealing gaps around baseboards or floor vents reduces how hard any heater has to run how to seal cracks in wood floors.

Use painter’s tape or a towel to test around window frames and under doors; if you feel a draft on your ankles, your heater is wasting watts. Pairing a right-sized electric heater with basic draft-proofing and the right style of heater for cold floors and rising drafts best heaters for cold floors and drafty rooms gives warmer wood floors and a lower power bill than simply buying a bigger unit.

Safe Heater Placement on Wood Floors

Heater placement on wood floors decides both safety and how warm your feet feel. For a hallway heater to warm the floor, put a tall oscillating tower at one end of the hall, out of the walking path, so it can sweep warm air along the boards. In a laundry room, use a cool touch model in the driest corner away from machines and sinks. Flat panel or so called flat heaters should sit on their legs or wall brackets, never face down on the floor or under a rug. A correctly sized wall panel heater can warm a small, tight room, but for quicker floor warmth an infrared or cabinet style heater at floor level works better, and when you switch an infrared heater off the air cools fairly quickly while the warmed floor and furniture give back heat for a short time.

Hallways with wood floors respond best to a heater that pushes warm air along the length of the space, not straight into a blank wall. A tall PTC ceramic heater in a tower format with oscillation, such as the Mountman 37 inch Space Heaters for Indoor Use, works well when you place it at one end, aimed down the hall and at least 3 feet from doors and trim. Keep the base fully on the boards, not half on a rug or threshold, so it cannot rock when people walk past. Oscillation does not harm wood floors; it simply stirs the air so hot spots and cold corners even out.

Hallway and laundry placement
In a hallway, tuck the heater to the side at the end of the run so you leave a full walking lane and do not blow straight at an open doorway. In a laundry room on wood floors, keep the heater at least 3 feet from washers, dryers and hanging clothes, aim it along the floor toward where you stand to fold or iron, and plug it directly into a wall outlet instead of an extension cord or power strip.
  1. Pick a flat, stable spot
    Set the heater on level wood, not on a step or loose object, so it cannot wobble or defeat the tip over switch.
  2. Maintain safe clearances
    Keep at least 3 feet between the heater and curtains, bedding, couches, wood furniture or laundry piles; do not hide it behind screens or furniture that trap heat against the floor.
  3. Aim heat along the floor zone you use
    Point a cabinet infrared heater toward your sofa or desk, and let a tower oscillate along the room so warm air washes over the boards where your feet actually are.
  4. Route the cord safely
    Run the cord straight to a wall outlet without crossing walkways or running under rugs, and do not coil extra cord under the base or behind the heater.
Do not hide heaters under rugs or furniture
Placing any heater under a throw rug, inside a cabinet or directly under a low sofa traps heat where it cannot escape. That can bake the finish on a wood floor, overheat the heater and increase fire risk, even on models with overheat protection and tip over switches.

A wall mounted panel heater can warm a room if you match its wattage and coverage to a small, well sealed space such as a bedroom or office. Because panels rely on gentle convection, they mostly warm the air and nearby walls rather than putting a strong beam of heat onto the floor, so wood boards will not feel as toasty as they do with a cabinet infrared heater or oil filled radiator parked at floor level. Always follow the manual for how much clearance the panel needs above the floor, below the ceiling and from side walls so heat can rise without scorching nearby surfaces.

Infrared heaters feel different because they warm solid surfaces first, then the air catches up. While the heater is running, the wood floor, furniture and your skin soak up radiant energy and feel comfortably warm even if the room thermometer reads lower. Once you turn the unit off, the air cools back toward the room temperature fairly quickly, but those warmed surfaces release their stored heat for a little while, so the chill does not return at once. If you like that focused feel, our infrared heater comparison explains where this technology shines and where a convection style heater works better.

Whatever heater type you choose, the safest placement on wood floors is the same. Keep the unit on a flat, stable surface, at least 3 feet from curtains, bedding and upholstered furniture, and where children and pets are less likely to bump it. Cabinet style infrared heaters such as the Dr Infrared Heater DR-968 Portable Space Heater and compact ceramic models like the R.W.FLAME Small Space Heaters for Indoor Use sit low and stable on the floor, but they still need open space around their intake and outlet grilles so air can move. An oil filled radiator works best near an interior wall with its long side parallel to the boards, giving a gentle wash of warmth along the floor without fan noise, as long as you leave airflow space and use a heater that carries a UL, ETL or CSA safety listing.

Comfort and Humidity With Heaters on Wood Floors

Humidity control matters as much as heat in a wood-floor room, for both your nose and your floorboards. Any plug-in electric heater can give you a dry nose or throat even if you do not have a cold, because warming the air lowers its relative humidity. The heater does not remove water from the room; it just raises the temperature, so the same moisture is spread through a larger volume of warm air. Your sinuses feel drier, and over weeks a very dry room can shrink boards, open gaps and stress the finish on wood floors.

That also means there are no true “heaters that retain room humidity” “; they all lower relative humidity as they warm the air. Some styles simply feel less drying. Oil-filled radiators and infrared cabinet heaters such as the Dr Infrared Heater DR-968 lean more on radiant heat and gentle convection, with slower-moving air, so people often notice fewer dry eyes and noses than with a small high-speed PTC ceramic fan heater blowing directly on them.

Heater typeHow the air usually feels
PTC ceramic fan heaterOften feels driest up close, because it heats air quickly and blows a strong stream directly across your skin.
Oil-filled radiatorGentle, even warmth with very little air movement; many people find it least irritating to noses and eyes.
Infrared cabinet heaterWarms nearby surfaces and people first, with a slower fan that usually feels less drying than a tiny desk heater.
Why some heater styles feel “drier” than others even at the same room humidity.
Comfort zone for you and your floors
Most hardwood flooring guidelines aim for indoor humidity somewhere in the middle range, not bone-dry and not damp. That same mid-band is where noses, throats and skin tend to feel best. A simple digital hygrometer on a shelf lets you see when heater use is pushing the room into very dry territory that is hard on both people and wood.

To reduce dryness, keep your heater at a moderate thermostat setting instead of running it flat out. ECO mode helps by cycling the heater off once the room reaches temperature instead of constantly baking the air. Adding a small cool-mist humidifier, or even setting a wide, stable bowl of water on a dresser away from the heater, can nudge humidity back up. Staying hydrated and avoiding very hot, very long heater runs will usually help more than cranking the room to 78°F.

Pair heat with a bit of moisture
In a closed wood-floor room, a 1,500 W heater plus a small humidifier on low often feels better than a bigger blast of dry heat alone. Aim for steady, moderate warmth with gentle moisture instead of sharp temperature swings.

Bathrooms flip the problem: steam keeps humidity high, but hard floors still feel cold without direct heat. Only use a heater that the manual specifically rates for bathrooms or damp locations, and plug it into a GFCI-protected outlet. Keep it well outside any splash zone and at least 3 feet from tubs, showers and sinks, and never touch controls with wet hands. The portable infrared and ceramic models on this page are meant for dry rooms, so reserve them for bedrooms, living rooms and offices, not steamy bathrooms or laundry rooms.

For comfort and humidity, a built-in thermostat, ECO mode and a timer matter more than chasing extra watts. A heater that shuts off at your setpoint instead of running nonstop keeps temperature, and therefore relative humidity drop, in a narrower band that is kinder to your sinuses and to wood. Timers let you preheat a room for an hour, then let the warmed floor and furniture coast without over-drying the air. If you are choosing a new unit, look for models with a thermostat, timer and solid safety features such as the options under overheat protection.

You can also feel warmer without pushing the heater so hard. Thick socks, a dense rug with a pad on top of the wood, a draft stopper at the door and insulating window film all cut heat loss and make the floor feel less icy at the same room temperature. These tricks let you keep the thermostat lower, so relative humidity stays higher and your nose and floors both feel better. If you are also fighting chill over other hard surfaces, the same comfort and humidity ideas apply; see best heaters for cold tile floors hallways or best heaters for a cold conservatory floor for heater choices sized to those spaces.

Why Wood Floors Stay Cold and What To Fix First

Cold wood floors usually mean heat is leaking out below or around the room, so how to fix cold floors starts with stopping those leaks before you pay for more heater watts. If you keep asking “why are my floors always cold”, look first at what is under the room, how drafty the baseboards and doors feel, and how much bare glass is near the floor. Those same steps help with heating cold floors without carpet and can even warm a room without a heater on mild days by keeping existing heat where you are.

The biggest culprits are uninsulated spaces under the floor (crawlspaces, basements, unheated garages, or a slab on grade), gaps at baseboards and around doors that leak outdoor air, and large windows or sliding doors that chill the air and dump it down across the floorboards. Wood itself is not the main problem; it takes on the temperature of the air and structure around it, so a leaky perimeter or cold void underneath will always make the surface feel icy at your feet.

Main CauseCommon CluesFirst Fixes
Uninsulated space belowRoom over crawlspace, basement or garage feels coldest at floor level; basement or garage ceiling shows bare wood with no insulationPlan under-floor insulation with a contractor; seal gaps at the rim joist; use thin rugs and mats as a temporary buffer for your feet.
Drafts at baseboards, outlets and doorsYou feel air movement at ankle height, see light under doors, or curtains move on windy daysCaulk along baseboards; add foam gaskets behind outlets and switches; weatherstrip doors and add door sweeps.
Large windows or sliding doorsFloor is coldest near glass; you notice a “cold waterfall” of air off the windowClose heavy curtains at night; add window insulation film; use draft snakes at the bottom of doors.
Match what you feel at the floor to the main source of heat loss.
  1. Map what sits under the room
    Stand in the cold room and picture the space below: basement, crawlspace, slab, or unheated garage. Floors over open or unheated spaces lose heat fastest and benefit most from insulation added to the underside of the subfloor.
  2. Seal baseboards and trim
    On a windy day, run your hand along baseboards, window trim, and pipe or cable penetrations; if you feel cold air, seal it with a small bead of flexible, paintable caulk. Focus on gaps where the baseboard meets the wall or floor so you do not glue floorboards together.
  3. Weatherstrip doors and windows
    Use adhesive-backed weatherstripping on door and window stops so the sash or door closes against a soft seal instead of a gap. Add screw-on or adhesive door sweeps to close the space between the door and the floor without dragging on your wood.
  4. Treat cracks between boards carefully
    If you can feel drafts through cracks between floorboards, check your flooring manufacturer guidance or talk to a flooring pro before filling them. Often they will recommend flexible wood-floor filler or rope filler that moves with the boards instead of rigid caulk or grout that can crack the floor.
  5. Block glass downdrafts
    Hang heavier curtains or cellular shades over large windows and sliders, and close them at night so cold air cannot spill down across the floor. On older or leaky windows, add clear window insulation film for the winter season.
  6. Add thin rugs, runners or mats where you stand
    Lay thin, dense area rugs, runners or foam mats by beds, couches, kitchen sinks and bathroom vanities so your feet stand on something warmer than bare wood without installing wall-to-wall carpet. Keep portable heaters on bare wood with at least 3 feet of clearance to any rug or mat on all sides.
  7. Aim heat at your legs and the floor
    Use an infrared heater or fan-forced heater positioned on a stable, hard surface so its outlet points toward your legs and the floor in seating or standing zones. That radiant warmth on your body and the surface is the key to heating cold floors without carpet.
  8. Plan insulation upgrades if floors stay icy
    If the floor is still cold after sealing drafts and adding rugs, especially above a crawlspace, unheated garage or bare basement ceiling, budget for professional under-floor insulation and air sealing. Done correctly, this usually improves whole-house comfort as well as floor temperature.

Heating cold floors without carpet is about creating warmer zones for your feet and using radiant heat where you actually sit and stand. Thin rugs and foam mats stop the wood from pulling heat out of your body, while an infrared heater aimed at seating or desk areas warms the surface and your legs instead of just the air near the ceiling.

To warm a room without a heater, focus on trapping the heat you already get from the sun and your main heating system. Close doors to unused rooms so warm air is not diluted, pull heavy curtains or close blinds at night, and add clear window insulation film on the coldest panes. Wearing warmer indoor clothing, socks and slippers does not fix the building, but it lets you set any thermostat or space heater a bit lower while staying comfortable, and these steps reduce how hard a heater has to run rather than replacing heat entirely.

When a cold floor needs more than DIY
Persistent cold floors over a crawlspace, unheated garage or slab, especially in a climate with real winters, usually mean the insulation or air sealing under the floor is missing or inadequate. An insulation or weatherization contractor can inspect the joist bays, rim joists and vapor barriers, then add the right type and thickness of insulation without trapping moisture. If you see sagging, mold, standing water or suspect structural damage, bring in a licensed contractor or structural engineer before adding insulation.
Draft sealing often beats more wattage
Most plug-in space heaters already draw about 1,500 W, which is close to the limit of a standard 15 A, 120 V circuit. Tightening up drafts and improving insulation often delivers more comfort per dollar than upgrading from one 1,500 W heater to another because the same heater can run on a lower setting or cycle off more often in a tighter room.

In very cold climates or leaky older homes, you may still need to pair these building fixes with a well-chosen space heater that is safe on wood floors and aimed where you feel the cold. If parts of your home with vinyl or tile floors are also icy, our best heater for cold rooms with vinyl floors and best heaters for cold tile floors in your home guides walk through space-heater options tuned to those hard surfaces, and our related guides on heaters for cold floors and drafty rooms cover more specialized solutions for rising drafts.

Frequently Asked Questions

Are oil-filled radiators better than ceramic heaters for rooms with wood floors?
Oil-filled radiators suit wood-floor rooms you heat for hours at a time because they give steady, low-intensity warmth and sit on wide feet or casters that spread their weight. A ceramic PTC heater is better for quick warmups, but its small base and hotter exhaust can focus more heat on one spot if you park it too close. For overnight comfort on wood floors, use an oil-filled unit as the main heater and keep ceramic towers for short stints or spot heat.
Does a room stay warm after you turn off an infrared heater?
An infrared heater stops adding heat as soon as you switch it off, but the surfaces it warmed—your wood floor, furniture and walls—will re-radiate some of that heat for a while. The room may feel comfortable for a short time if it is reasonably insulated, then cool gradually like it would with any other space heater. Infrared does not create permanent warmth; it just directs more of the heater’s output into people and surfaces while it is running.
Can a wall panel heater actually heat a whole room with wood floors?
Yes, but only if the wall panel’s wattage is high enough for the room size and the room is fairly well sealed. Many plug-in wall panels are lower powered than a typical 1,500 W portable heater, so in a big or drafty room they work best as background heat alongside another heater. In a small, closed room with wood floors, a panel heater mounted on an interior wall can keep the chill off the floor without taking up floor space.
What type of heater is least likely to dry out my nose and throat?
Any heater that raises the room temperature will lower relative humidity, but models that run cooler elements and move less air feel less drying. Oil-filled radiators and gentle infrared panels usually feel kinder to your nose than high-speed ceramic fan heaters blowing straight at you. Pair whichever heater you use with a small humidifier and avoid overheating the room to keep your nose and throat more comfortable.
Is it safe to use a space heater in a bathroom with wood floors?
Using a space heater in a bathroom is only safe if the heater is specifically rated for bathroom or damp-location use and plugged into a GFCI-protected outlet. Set it on a flat, dry section of the wood floor at least 3 feet from the tub, shower and sink, and never where water can splash on it. Many portable heaters are labeled “not for use in bathrooms,” so check the manual and choose a bathroom-rated model or a hardwired heater instead. Avoid any fuel-burning or outdoor-rated heater in a bathroom, regardless of the floor type.
What kind of heater can I use during a power cut in a cold room with wood floors?
During a power cut you need a non-electric heat source that is explicitly rated for indoor use, such as a vented gas heater or an indoor-rated catalytic propane heater. Follow the manual for clearances to your wood floor and nearby furniture, and run a working carbon monoxide alarm in the same room. Never bring an outdoor patio, garage or construction heater inside, and if you do not have a safe indoor fuel heater, rely on insulation—rugs, layers and closed doors—until power is restored.
