If your bathroom mirror fogs over the second the shower starts and the floor tiles feel like ice at 6 a.m., the fix is one ceiling unit that does two jobs at once: pull the damp air out and push warm air down. The catch most shoppers miss is that exhaust power and heat power are separate numbers, and a fan can be strong at one while weak at the other. Below are eleven combos that actually pair both — sorted so the best-balanced units sit at the top and the tightest-budget picks come last.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Airflow is measured in CFM (cubic feet per minute — how much air the fan moves out), and heat comes in watts, so the right pairing depends on your room’s square footage. This breakdown of the bathroom vent fan and heater market separates the quiet, hard-working ceiling combos from the ones that only look the part.
Our Picks at a Glance
How To Choose The Best Bathroom Vent Fan And Heater
A combo unit lives or dies on three numbers: airflow in CFM, loudness in sones, and heater power in watts. Get those three matched to your room and the rest is installation detail.
Match CFM To Your Square Footage
For a standard full bath, 110 CFM is the common target and clears steam fast. Small powder rooms and half baths do fine at 70 to 80 CFM. A few models here let you pick the airflow at the flip of a switch, so the same unit works whether you upgrade rooms later or want less noise during a quick wash-up.
Sones Decide Whether You Actually Use It
Sones are how loudness is rated — a lower number is a quieter fan. A 1.5-sone unit is roughly a soft hum you stop noticing. A 4.0-sone unit is noticeably audible, which some people want for privacy. The trade is real: a quiet fan is easier to forget, so pair it with a timer.
Heater Type And Coverage
PTC ceramic heaters (a self-regulating ceramic element that warms air as it passes through) deliver warmth within minutes and are the modern standard in this category. Infrared and radiant-bulb heaters throw heat differently and depend on the bulb you install. Either way, check the manufacturer’s stated heating coverage in square feet against your room.
The Details That Decide Your Install
Confirm three things before ordering: your ceiling cutout size, your duct diameter (4-inch and 6-inch are the common options here), and whether the heater needs its own dedicated circuit. Most heater combos in this list call for a dedicated 20-amp circuit, and a unit wired to a shared line is a common cause of early failure. Also decide controls — a wall switch, a timer, or a handheld remote — because that choice affects how much wiring you touch.

In‑Depth Reviews
1. Panasonic FV-0511VHL1 WhisperWarm Bath Fan +Light + Heater
Our pick — over 4.5★ from 250+ verified ratings; the strongest balance of quality and price.
The whisper-quiet ceiling combo that pushes the most air and the most heat at once.
What earns this Panasonic the top spot is a pairing you won’t find everywhere: 110 CFM of airflow next to a 1600W PTC heater, with a dimmable 3000K LED panel and a night light that sips less than 1W. Against the 70 CFM Broan infrared unit, this moves 57% more air, so a steamy full bath clears in fewer minutes. Buyers report the strongest single impression is how little they hear it, and the build quality backs that up.
The Pick-A-Flow switch lets you dial the fan between 50, 80, or 110 CFM to match the room, and the Flex-Z Fast bracket means a single-hinge hanger sits it in place without you crawling into the attic. It fits 4-inch or 6-inch ducting, so it plays nice with the duct you already have. You still need a dedicated 20-amp circuit — that’s the one line to plan around before install day.
One buyer summed the whole experience up in the review pages: “You should run your fan for 20 minutes after a shower and this is so quiet that you may not notice it running, Best I have found.” That sums the trade-off too: because it’s this quiet, you genuinely need a timer, or it just runs. The only consistent debate in the notes is on price.
Where This One Earns Its Spot
- 1600W PTC heater plus 110 CFM — the fullest combination of warmth and airflow here
- 50/80/110 CFM Pick-A-Flow switch adapts to room size without a swap
- Dimmable 3000K LED with a sub-1W night light built into the cover
The Details To Plan Around
- Needs a dedicated 20-amp circuit — budget for an electrician if you don’t have one
- So quiet you must set a timer or it runs unnoticed
- The LED sits in the cover, so its replacement path is worth understanding up front
Built for: anyone wanting one ceiling unit to both dry the room and warm it, with the dial-in airflow headroom to handle a bigger bath.
Look past it if: you don’t have a spare breaker slot for a dedicated 20-amp run, or you want a light-free fixture.
2. Broan Ceiling Bathroom Exhaust Fan/Infrared Heater, 70 CFM, 250-Watt
The small-room hero: 70 CFM of exhaust and a bulb heater in one flush ceiling unit.
If your bathroom is a compact powder room or half bath, this is where the value sits. It moves 70 CFM at 4 sones, which is the lower end on both counts but a sensible match for a smaller space — you get real ventilation and real heat without overspending on airflow you’ll never use. The 250-watt radiant heat comes from a single 250W BR40-size infrared bulb (one of the few models in this whole lineup where brightness and heat are separate purchases).
Installation reports skew friendly. The adjustable mounting brackets drop into the existing opening, and the white grille can be painted to hide in the ceiling. The consistent notes say the quietness surprises people. Where it can be finicky is the wiring: the stranded copper leads are fiddly to join to 12-gauge or 14-gauge household wire, so pre-tinned leads or a bit of care with wire nuts make the job smoother.
The honest catch here is heat reach. At 250 watts this is a spotter, not a room-filler — it warms the small space it’s rated for (about 65 square feet) but won’t blanket a full bath. Even so, this is a reliable replacement for an aging Broan or NuTone unit, and the fit and finish hold up. Keep it in its lane — small-room warmth — and it delivers exactly what you asked.
Small-room specialist: 70 CFM at 4 sones is a privacy-positive fan for a half bath, and the 250W infrared bulb warms the person in front of it more than the whole room.
An easy pick for: a powder room or guest bath needing both a fan and a little warmth, especially as a straight replacement for an old Broan-style unit.
Think twice if: you have a full-size bathroom and want heat that fills the whole room — step up to a 1300W or 1500W heater for that job.
3. Delta Breez Radiance Bathroom Exhaust Fan with Light, Heater & Thermostat
A thermostat-protected 3-in-1 that quietly turns a cold bathroom warm every morning.
This Delta Breez pairs an 80 CFM fan with a 1300-watt heating element and a brushless DC motor rated to run up to 70,000 hours at 7 CFM per watt — a power-efficient combo that runs cool and lasts. The 1.5-sone rating keeps it quiet, and a thermal cutoff fuse plus thermostat mean the heater shuts off before it can overheat. There’s no light-free confusion here: the integrated light is part of the single-ceiling-unit package.
Where owners land strongly is on how quickly the heat arrives and how well it clears a damp room. A common note is that after installation, the bathroom mirror stops fogging during showers, and the space stays warm even while wet. The recurring practical point is that the heater wants its own dedicated circuit — one owner traced a short-lived heater back to wiring it into the wrong line, and correctly wiring it made it work reliably. So the circuit is the make-or-break.
The honest limits are brightness and quiet volume. Some find the light adequate rather than brilliant, and a few say airflow is fine but not overwhelming. The installation itself can lean involved if you’re replacing a plain vent fan with this light-and-heat unit — some report needing new wiring and switch work, which adds labor. Given the 1300W heater, treat it as a fixture you plan once and forget for years.
Thermostat confidence: the built-in thermal cutoff and thermostat make this a heater you can run without babysitting — a thoughtful safety touch for a cold-morning routine.
Plan the circuit: wire it to its own dedicated line as the manufacturer directs; that single detail is what separates a heater that runs for years from one that trips out early.
Right choice for: a small-to-mid bathroom wanting quiet, energy-efficient fan-plus-heat with a thermostat doing the thinking.
skip it if: you want a blindingly bright light or a fan that pushes maximum CFM — this one prioritizes quiet and efficiency over sheer output.
4. Air King AK55L Combination Ceramic Heater with Exhaust Fan and Light
A three-in-one built for swapping out an aging unit without redrawing the whole ceiling.
Air King’s AK55L sets itself apart with a self-regulating ceramic heater that puts out 1350 watts, plus a moonstone glass lens that won’t discolor under the heat of a bulb or from age — the kind of detail you appreciate in a fixture that lives above your head for a decade. The fan moves 70 CFM at 5.0 sones, which is a solid performer if your space is around 70 to 85 square feet. Three blowers share the housing: a heater blower, a ventilation blower, and the light, each built to run independently.
The practical draw is its retrofit shape. The grilled size and housing are built to drop into a standard opening, and reports say it’s a clean replacement for a similarly sized older unit. A 4-inch metal duct collar with a backdraft damper is included, along with hanger bars and mounting hardware, so most of the fitting is in the box. If you’re replacing the exact old model, expect a close-but-not-identical match — one builder noted it was nearly the same as the 5-year-old unit he was swapping out.
The honest friction is sound. With a 5.0-sone rating, this is noticeably louder than the whisper-quiet Panasonic above, and multiple reviews mention a hum that carries. Heat output draws a split read too — some love the ceramic warmth, others want more. Wiring is best left to someone comfortable with a 20-amp circuit; a couple of owners hired an electrician rather than tackle it themselves.
Why It Fits A Retrofit Job
- 1350W self-regulating ceramic heat with a lifetime-clean moonstone lens
- Includes 4-inch duct collar, backdraft damper, hanger bars and hardware
- Handles a 70 to 85 sq ft room on 70 CFM
Where It Asks A Compromise
- 5.0 sones — noticeably louder than the quietest combos here
- Mixed notes on how much heat actually reaches the room
- A 20-amp circuit and comfort with wiring are part of the deal
Worth it for: a like-for-like replacement of an older 3-in-1 where matching the opening matters more than whisper sound.
Choose quieter instead if: your bathroom is close to a bedroom and 5.0 sones of fan hum would keep anyone awake.
5. VIVOHOME 4-in-1 Bathroom Exhaust Fan with Light and Heater, 1800W PTC
The airflow heavy-lifter: three speeds up to 160 CFM, paired with the biggest heater here.
If your bathroom is on the large side or you simply hate waiting for steam to clear, this is where the numbers get serious. VIVOHOME’s unit delivers three-speed airflow at 80, 110, and 160 CFM — the highest ceiling in this lineup — on a 40W brushless DC motor that runs at just 0.5 to 1.5 sones. That’s the widest airflow range you can get in a single ceiling fan, and the 1800W PTC ceramic heater is the most powerful heater in the group. Five heat settings and a smart dry mode (25 minutes of heat, then 5 minutes of exhaust) round out the automation.
The lighting swings both ways: a 13.5W LED panel covers three color temperatures — 2700K, 4000K, and 5700K — and remembers your last setting. A wireless remote runs the whole show, and a humidity sensor can kick the fan on when it senses shower steam. Ducting is a 4-inch connection, and the housing fits a standard 10.8 by 10.8-inch ceiling opening.
The trade to know: the remote gets mixed feedback, with several owners reporting controller issues — some even swapped the remote out for a wall switch. Installation notes warn that 1/2-inch drywall may need extra backing, so check your ceiling material before you start. And with 160 CFM on tap, this is a fan sized for a bigger room; put it in a tiny powder room and it’s more than you need.
Power for the price: 160 CFM and 1800W in one unit is the strongest raw combination on this list, and the humidity sensor makes it genuinely set-and-go.
The catch to weigh: the remote is the weak link — several owners ended up preferring a manual wall switch because the controller misbehaved.
Made for: a big bathroom or one with a high ceiling that needs real airflow and serious warmth in a hurry.
Overkill if: you have a small half bath — the 160 CFM top speed is far more than a compact room needs.
6. GROWNEER 4 in 1 Bathroom Exhaust Fan with Heater and Light, 110 CFM
A remote-controlled 4-in-1 that brings 1700 watts of heat without stretching a budget.
For the money, this GROWNEER covers a lot of ground: a 1700-watt heater with built-in overheat protection, a 110 CFM fan running at 1.5 sones on a 35W motor, and a wireless touch-sensitive remote that flips the light through three color temperatures — 2700K, 3500K, and 5000K. The ceiling opening is a standard 10.83 by 10.83 by 6 inches, and it takes a 4-inch vent duct.
What owners like most is the heating performance and how straightforward it is to swap in. Several note it warms the bathroom quickly and the install was simpler than expected — one mentions reusing the wiring from the plain vent fan it replaced, which keeps the job light. The automatic overheat shutoff is a popular detail: the element cuts itself when it gets too hot, so you don’t have to watch it. It’s also worth knowing that the remote replaces the switches, so this unit runs entirely off the handheld controller rather than a wall switch.
Two fixed caveats are worth planning for. First, the remote is the only way to operate the fan and light — no wiring it to a wall switch — so if the remote fails you’d be replacing the whole unit, and one owner flagged exactly that concern. Second, the exhaust hose flange is a touch short, which can make a retrofit install fussy. And a few owners found the fan louder than they’d like, so a quiet unit matters more to you than budget, look upward.
The trade you’re making: you’re trading a wall switch for a remote. That’s fine until the remote dies, at which point the whole fixture becomes the repair.
Strong Points
- 1700W heater with automatic overheat shutdown at a budget-friendly tier
- Three LED color temperatures via remote — 2700K, 3500K, 5000K
- Standard 10.83-inch cutout and 4-inch duct make swaps easier
Points To Note
- Remote-only operation, so no wall-switch backup
- Exhaust hose flange runs short, complicating retrofits
- Some owners wish the fan were quieter
Best for: budget-conscious buyers upgrading from a plain vent fan who don’t mind controlling everything from a remote.
Reconsider if: you insist on a physical wall switch for the light and heat — this one is remote-only.
7. Broan-NuTone Non-Lit PowerHeat Bathroom Exhaust Fan and Heater, 110 CFM
The pure heater: 110 CFM and 1500 watts with no light to complicate the wiring.
Some bathrooms already have their lighting sorted, and this is the pick for them — a fan-and-heater combo with no integrated light at all. It delivers 110 CFM across up to 105 square feet at 2.0 sones, and the 1500-watt heater warms the room on its own. The fan and heater run independently or together, so you can vent steam after a shower without paying for heat, or run both on a cold morning. It’s engineered for continuous operation, which matters in a damp bathroom.
The housing is compact and fits 2 by 6-inch ceiling construction, with a rugged galvanized steel body and a white grille that disappears into the ceiling. The finish and fit are the kind of thing owners notice when they’re up on a ladder — one noted the whole installation was easy and the unit wasn’t too loud. Because there’s no light bulb in the equation, the entire fixture is one simple on/off-heat-venter, which is its own kind of reliability.
Its size is its one liability. At 105 square feet of coverage, it’s built for a full but not oversized bath, and going bigger than that leaves it short of breath. The sound level is a matter of taste — the fan is higher-CFM than the small Broan above, so it’s a touch more audible. Check your ceiling joist spacing and pick a duct route before ordering; this is a permanent install, not a plug-in.
What Makes It Handy
- 110 CFM clears up to 105 sq ft at 2.0 sones
- 1500W heat, no bulb or LED to wire or replace
- Fan and heater operate independently or together
A Couple of Limits
- No light — you need separate bathroom lighting
- Better suited to a standard full bath than a very large one
- Slightly more audible than the 1.5-sone quiet combos
A natural fit for: a full bathroom that already has good lighting and just needs clean ventilation plus warmth.
Look elsewhere if: you want the light built into the same ceiling unit — you’ll want a lit combo instead.
8. breez Bathroom Exhaust Fan RAD80LED – LED Light & Heater – 80 CFM
A quiet, odd-size-friendly combo built to rescue an aging bathroom fan opening.
This breez Radiance unit is shaped for a specific problem: replacing a fan whose opening doesn’t match the common sizes. Its compact 8-by-14 footprint slides into older openings, and a dimmable 13W LED gives it a light that owners say brightens the whole bathroom. The fan runs at 80 CFM and 1.5 sones on a brushless DC motor rated up to 70,000 hours, with a 7.0 CFM-per-watt efficiency figure — one of the more efficient units here.
Two clever touches stand out in the reviews. First, the fan, light, and heater can be wired to separate switches, so you can run the vent on its own switch and the heater on a 60-minute timer. Second, the grille is a simple flush-mount cover secured by spring clips, so maintenance is a matter of releasing the clips and wiping the housing — no tools required for cleaning. Appearance-wise, the modern grille is a step up from the yellowed plastic it typically replaces.
The one honest hold-back is airflow. At 80 CFM with a mixed reviewer read, some find it clears steam fine while others want a stronger pull — especially in a larger bathroom. Heat output is on the modest side, so treat this as a small-to-mid-bath heater rather than a whole-room furnace. Give it a 2 to 7-square-foot bathroom or so and it’s a satisfying, quiet upgrade; oversize its job and you’ll wish for more power.
Fit and finish focus: the standout trait is how painless upkeep is — the spring-clip grille and dustable housing make the routine maintenance nobody thinks about genuinely quick.
Where it falls short: the 80 CFM airflow leaves some owners wanting more air movement, so factor in room size before choosing it.
Ideal for: a small or mid-size bathroom with an older, odd-sized fan opening, especially when low noise and easy cleaning top your list.
Not the right call if: your bathroom is large and steamy — 80 CFM may not move enough air for you.
9. Broan-NuTone BHFLED110 PowerHeat Bathroom Exhaust Fan, Heater, and LED Light Combination
Bright, color-adjustable light, a 1500W heater, and 110 CFM all working from one switch.
This is the version to look at if you want the brightest light plus real heat in a single ceiling fixture. It runs 110 CFM at 2.0 sones, packs a 1500-watt heater, and layers in a dimmable LED with CCT color control — you can pick warm white at 2700K, bright white at 3500K, or daylight at 5000K to match your bathroom’s mood. The fan, light, and heater run independently or together, so you can vent the room without heating it, or heat it without lighting it.
Owners who use this as a daily driver tend to single out the instant, reliable heat — one calls it “by far my favorite vent fan,” noting the heat is perfect and it clears the bathroom well. The squirrel-cage fan design is a step up from cheaper units and helps keep the noise in check. The housing is compact and fits 2 by 6-inch ceiling construction, at 16 by 10-1/4 by 5-7/8 inches, and it requires a dedicated 20-amp circuit, so plan the wiring before install day.
The recurring compromise here is installation and noise, both of which read mixed. Several owners found the install moderately challenging and noted no switches are included, so a wall switch setup is extra wiring if you want one. On sound, some are surprised by how quiet it is while others find it a bit loud for the air it moves — for a room sized 100-ish square feet it’s a fair performer, but a high-ceiling bathroom will want more heat output.
The lighting win: three color temperatures on a dimmable LED means you get a night light, a bright morning white, and everything between — rare in a single-ceiling combo.
The install to plan: it needs a dedicated 20-amp circuit and doesn’t come with switches, so budget the electrician’s time if you’re not comfortable with wiring.
A strong match for: a bathroom around 100 square feet where you want fast heat and a customizable, dimmable light in one unit.
Skip if: your bathroom has tall ceilings or you want the absolute quietest fan possible — both are trade-offs this unit lives with.
10. Broan 100HL Bathroom Fan, 100 CFM for 4″ Ducts w/100W Max Incandescent Light & Heater
The do-it-yourselfer’s combo: a 100 CFM fan, 1500W heater, and a standard incandescent light.
For anyone swapping out an old combo without calling in help, this Broan is built to make that easy. It runs 100 CFM on a 4-inch duct, includes a 24-inch adjustable hanger bar system and a 4-inch duct connector straight in the box, and fits 2 by 6-inch ceiling construction for bathrooms up to 90 square feet. The 1500-watt heater, 100 CFM fan, and a 100W-max incandescent light (bulb not included) each work independently or together.
The reason it keeps showing up in DIY stories is the installation: the hanger bars bend to fit varied framing, and the plug-in modules simplify wiring. One long-term owner has run theirs for seven years of daily use, and another used it as a direct swap for a 25-year-old Broan unit. The heater warms a 100-square-foot room quickly and the fan clears steam, though a faint lingering mirror haze is a common note in smaller spaces. Multi-function wall switches are sold separately, so you can pick your own control setup.
The one thing to take seriously is heater longevity. A portion of owners mention the heating element giving out within a couple of months, or the heater dying after 2.5 years of light use — and the common thread is a long-run burnout issue, which is why several owners put the heater on a timer rather than a manual switch. Wire it to its own 20-amp circuit, use a timer to limit heater run time, and it holds up far better than an unmanaged setup would suggest.
Why DIYers Like It
- 24-inch adjustable hanger bars and included 4-inch duct connector
- Simple plug-in modules and removable motors make install quick
- 1500W heater warms a 90 sq ft bathroom fast
Worth Knowing Before You Buy
- Heater element has a reputation for burning out when run for long stretches
- Wall switches are sold separately — factor that into your plan
- Some find the fan leaves a little mirror steam in small rooms
A good call for: confident DIYers replacing an old combo who want a full-featured unit that installs from the box.
Use a timer if: you pick this one — running the 1500W heater on short timer cycles is the single best way to protect the element.
11. Panasonic FV-0511VH1 WhisperWarm Bath Fan + Heater, 50-80-110 CFM
The quiet whole-room warmer for bathers who don’t need a built-in light.
This is the light-free sibling of the top pick, and it exists for one simple reason: some bathrooms have plenty of lighting and just want quiet heat andclean air. It runs the same 1600W PTC heater and the same Pick-A-Flow engine that lets you choose 50, 80, or 110 CFM with a switch, wrapped in an Energy Star-certified DC/ECM motor housing. The Flex-Z Fast bracket installs without attic access, and it takes either 4-inch or 6-inch ducting.
What owners consistently praise is the quiet followed by the instant warmth — the two things that make a cold-morning shower tolerable. The build quality reads as the other headline trait, with the housing and grille feeling solid and the motor sized to run for years. A slight delay before startup is the one recurring quirk worth knowing: the fan takes a few seconds to spin up after you flip the switch, which some owners initially mistake for a fault until they understand why it’s there.
The honest trade here versus the top pick is light. If you want the integrated LED and night light, the 0511VHL1 has it and this one doesn’t — otherwise the airflow and heat specs are the same. It also wants that dedicated 20-amp circuit, so the electrical plan is identical. For a bathroom that already lights well, this quietly does the venting and heating without adding a light you’d never use.
Where It Wins
- 1600W PTC heater warms chilly bathrooms fast
- Pick-A-Flow 50/80/110 CFM switch adapts to room size
- Energy Star-certified DC/ECM motor with Flex-Z Fast bracket install
Worth Noting
- No integrated light — you need separate bathroom lighting
- Short startup delay after you flip the wall switch
- Requires a dedicated 20-amp circuit
The one to reach for: a well-lit bathroom that mainly needs quiet, powerful heat and ventilation without adding another bulb to the mix.
Better off with the lit version if: you also want a built-in LED panel and night light — that’s the only thing this unit gives up.
Understanding the Specs
CFM and Room Size
CFM stands for cubic feet per minute — the volume of air the fan pushes out. A 70 CFM fan is plenty for a small powder room, while 110 CFM and up suits a standard or large bath. Some models let you switch between settings, so the same unit can scale to the room. The key is matching airflow to square footage, not buying the biggest number you can find.
Sones and Quietness
Sones measure how loud the fan sounds to the human ear. A 1.5-sone rating is a faint hum, 2.0 is still gentle, and 5.0 is clearly audible. Quieter fans are easier to live with but easier to forget, which is why a timer is such a common upgrade. If your bathroom is near a bedroom, prioritizing a low-sone unit pays off every night.
Heater Power and Type
Heater output is measured in watts, and the higher the number, the faster the warmth arrives. PTC ceramic heaters are the modern standard: a self-regulating element that warms air as it passes through and shuts off safely at higher temperatures. Infrared and radiant-bulb heaters warm the person in front of them more than the whole room, which suits small spaces. Either way, check the manufacturer’s stated square-footage coverage.
Ducting, Cutouts, and Wiring
The duct size a fan accepts is usually 4-inch or 6-inch, and it must match your existing run. The ceiling cutout size is the other measurement to confirm before you buy. And pay attention to the electrical requirement: most heater combos in this list call for a dedicated 20-amp circuit, and wiring a heater to a shared line is a common cause of early failure. Confirm all three — duct, cutout, circuit — before you order.

Final Thoughts: The Verdict
If you want one dependable pick, the bathroom vent fan and heater winner is the Panasonic FV-0511VHL1 WhisperWarm because it pairs the highest airflow in this lineup with the most headroom in both heat and light settings — the fan moves 57% more air than the 70 CFM Broan infrared unit at a fraction of the noise. It’s the one pick that checks every box: strong heat, dial-in CFM, a dimmable LED, and a night light.
If built-in lighting isn’t a priority and you want the same quiet motor and 1600W PTC heater without the LED, grab the Panasonic FV-0511VH1 WhisperWarm instead. And for a large bathroom where airflow and heater wattage are the whole game, the VIVOHOME 4-in-1 brings 160 CFM and 1800W into a single ceiling unit — just be ready to live with the remote.
