A bathroom that feels like a cold cave on winter mornings is a problem solved by a single ceiling unit. The right bath fan with heater combines ventilation to strip humidity with forced warmth that makes stepping out of the shower tolerable. But the market splits between infrared bulbs, ceramic PTC elements, and standard coil heaters — each with different noise profiles, installation demands, and real-world heating speed.
I’m Rikta — the founder and writer behind FitlyFast. I’ve spent years analyzing home improvement hardware specifications, comparing CFM ratings, sone levels, and heater wattage to separate effective units from frustrating ones.
This guide breaks down the key differences between the seven best-selling models so you can choose the right bath fan with heater for your space without wasting time on a unit that underperforms.
How To Choose The Best Bath Fan With Heater
Selecting the right unit means balancing three competing priorities: how fast the heater warms the room, how quietly the fan moves air, and whether the light integration fits your bathroom layout. The wrong choice leaves you with a noisy fan, weak heat, or a duct that doesn’t match your ceiling construction.
Heater Type and Wattage
The heating method defines the experience. Infrared bulb heaters (250 watts) produce localized radiant warmth — they heat the person below the bulb, not the room air. This works for small spaces or spot heating near a vanity. Forced-air ceramic PTC heaters (1300–1700 watts) push warm air into the room and raise the ambient temperature faster, making them the better choice for full-room comfort. Standard coil elements dry the air more and can create hot spots.
CFM Meets Square Footage
The Home Ventilating Institute recommends 1 CFM per square foot of bathroom area. A 70 CFM fan handles a room up to 70 square feet. A 110 CFM unit covers up to 110 square feet. Undersizing leaves steam on the mirror and moisture in the drywall. Oversizing with a very high CFM can pull conditioned air out of the house too quickly, wasting energy.
Noise Level in Sones
A sone measurement tells you how loud the fan sounds to the human ear. One sone is roughly the sound of a quiet refrigerator. Fans rated at 1.5 sones or lower are barely noticeable during conversation. Units at 4 sones or higher produce a distinct hum that some users find intrusive, especially if the fan runs during sleep hours.
Installation and Ceiling Fit
Not all units fit the same ceiling cavity. Some require 2×6 joist spacing, others fit 2×4. Many premium models need attic access for wiring and duct connection. Replacement of an older unit is easiest when the new housing matches the same cutout dimensions — the Broan-NuTone 162 and the Broan 100HL are common drop-in replacements for older models because their housings align with standard hole sizes.
Light Integration and Control Options
Modern combos now include tunable LED lights with color temperatures from warm 2700K to daylight 5000K. Some models offer dimmable lighting, which eliminates the need for a separate dimmer switch. Remote control models simplify operation but require battery changes and reliable RF signal through the ceiling drywall.

In‑Depth Reviews
1. VIVOHOME Bathroom Exhaust Fan with 1600W PTC Heater, Humidity Sensor & LED Light
The VIVOHOME unit packs the most versatile set of features in this lineup. Its brushless DC motor delivers three adjustable fan speeds (80, 110, 160 CFM) while keeping noise between a whisper-quiet 0.1 and a modest 1.5 sones. The 1600W PTC ceramic heater has five temperature settings and an auto-adjust mode that targets 38°C for consistent warmth without manual fiddling.
What sets this model apart is its smart dry mode — 25 minutes of heating followed by 5 minutes of exhaust-only running to prevent overheating and clear residual steam. The humidity sensor automates ventilation when moisture spikes, which is useful for families who forget to flip the switch. The 12W LED panel offers three color temperatures (2700K, 4000K, 5700K) with a memory function that recalls your last setting.
Installation requires a 10.8 x 10.8-inch ceiling opening with a 4-inch duct. The unit uses a wireless remote control, which means no wall switch wiring for the heater — but the remote itself is small and requires two AAA batteries. Some users reported needing custom framing to properly support the housing in 1/2-inch drywall.
Why it’s great
- Variable CFM and sone levels adapt to different room sizes and noise tolerances
- Humidity sensor with auto-dr y mode reduces manual operation
- Tunable LED with memory function eliminates the need for a separate light switch
Good to know
- Remote control is very small and easy to misplace
- No adjustable timer — the only timed cycle is the fixed dry mode sequence
- Installation can be complex; manual uses metric measurements
2. Broan-NuTone BHFLED110 PowerHeat Bathroom Exhaust Fan, Heater, and LED Light Combination
The BHFLED110 is Broan’s most refined combo unit, combining a 1500W forced-air heater with a dimmable LED light that lets you cycle through 2700K, 3500K, and 5000K color temperatures. The 110 CFM airflow at 2.0 sones is quiet enough for conversation while still clearing steam from a bathroom up to 110 square feet. The forced-air heat element is noticeably faster than infrared bulbs at raising room temperature.
The integrated LED light is bright enough to serve as the primary bathroom light, which simplifies wiring by removing the need for a separate fixture. The dimmable function adds flexibility for nighttime use. The heater draws approximately 12 amps, so a dedicated 20-amp circuit with 12 AWG wire is recommended — several user reports confirm that sharing a circuit with other loads can cause nuisance tripping.
Installation is not for beginners. The housing measures 16 x 10.25 x 5.875 inches and requires attic access for wiring and duct connection. Replacing an older unit of a different brand may involve cutting new ceiling holes and running new Romex. Owners who paid a professional for installation considered it money well spent.
Why it’s great
- Dimmable LED with adjustable color temperature eliminates a separate light fixture
- Forced-air heater warms the full room, not just a spot below the bulb
- Quiet operation at 2.0 sones with effective moisture removal
Good to know
- Installation requires attic access and is difficult as a DIY replacement
- Requires a dedicated 20-amp circuit for safe heater operation
- Forced-air fan produces a slight vibration sound when the heater runs
3. GROWNEER 4 in 1 Bathroom Exhaust Fan with Heater and Light
The GROWNEER 4 in 1 delivers the highest heater wattage in this group at 1700W, making it the fastest option for warming a cold bathroom. At 110 CFM and 1.5 sones, the fan strikes a good balance between airflow and noise — it moves enough air for a medium bathroom without drowning out conversation. The 35W DC motor is energy-efficient and contributes to the quiet operation.
The 3-color LED light cycles through 2700K, 3500K, and 5000K, controlled through a wireless touch-sensitive remote. The remote does not require line-of-sight, which is helpful when mounted outside the bathroom. The built-in overheat protection automatically cuts the heater if internal temperatures climb too high — a safety feature that’s especially important for units installed in tight ceiling cavities.
The ceiling opening requirement is 10.83 x 10.83 x 6 inches with a 4-inch duct. The housing is made of ABS+PP plastic, which resists bathroom moisture and yellowing better than some metal units with painted finishes. Some users noted that the noise level, while rated at 1.5 sones, is slightly higher in actual use than the quietest competitors.
Why it’s great
- Highest heater wattage (1700W) for fastest warm-up time
- Quiet DC motor with solid 110 CFM airflow
- Moisture-resistant ABS housing avoids yellowing
Good to know
- Remote requires separate batteries and is easy to lose
- Some users report actual noise is slightly above the rated 1.5 sones
- Mounting bracket not included; must be purchased separately
4. Delta Breez Radiance Bathroom Exhaust Fan with Light, Heater & Thermostat
Delta Breez has built a reputation for quiet, reliable ventilation, and the Radiance model continues that trend. At 1.5 sones, this is one of the quietest units in the comparison, making it ideal for bathrooms adjacent to bedrooms or nurseries. The 1300W heating element is paired with a thermostat and thermal cutoff fuse to maintain safe operating temperatures automatically.
The brushless DC motor is rated for 70,000 hours of continuous use — roughly 8 years of nonstop running. At 7 CFM per watt, it’s also one of the most energy-efficient models here. The integrated light provides even illumination through a sleek modern grille, but note that it is not tunable — you get one color temperature. The 80 CFM airflow is adequate for bathrooms up to 80 square feet, but may struggle with larger master baths.
One design quirk: the heat blows at a 45-degree angle from the side of the unit due to fixed grill fins. For small bathrooms where the toilet or vanity is directly under the unit, the angled heat may miss the user. Electrician installation runs about two hours for a replacement, but the quiet operation earns consistent praise from owners.
Why it’s great
- Extremely quiet at 1.5 sones — barely noticeable during operation
- Long-life brushed DC motor rated for 70,000 hours
- Thermostat-controlled heating with thermal cutoff for safety
Good to know
- 80 CFM limits use to bathrooms under 80 square feet
- Heat blows at a fixed 45-degree angle; may not reach the person directly below
- Heater element failure reported after 5 years in some installations
5. Broan 100HL Bathroom Fan, 100 CFM with 100W Max Incandescent Light & Heater
The Broan 100HL is a workhorse that has been on the market for years. It delivers 100 CFM of ventilation paired with a 1500W heater and a standard 100W incandescent light socket. The light uses an A19 bulb (not included), which means you can choose your own brightness level and color temperature — a flexibility that built-in LEDs do not offer.
The housing is designed to fit 2×6 ceiling construction and uses a 4-inch duct connector with adjustable hanger bars. The unit is HVI-certified and works in bathrooms up to 90 square feet. The 20-amp circuit requirement is critical — users who used a standard 15-amp circuit experienced heater element burnout within weeks. With proper wiring and a timer switch rated for the 1500W load, owners report trouble-free operation for seven years or more.
Noise level is not officially rated in sones, but user feedback places it around 3 to 4 sones — louder than the Delta Breez or VIVOHOME, but acceptable for most bathrooms. The light can be wired to operate independently, which is useful for separating the fan, heater, and light onto different switches.
Why it’s great
- Proven longevity — multiple user reports of 7+ years of daily use
- Standard light socket allows bulb customization
- Reliable 1500W heater with good coverage for small to medium bathrooms
Good to know
- Heater element can fail prematurely if not on a dedicated 20-amp circuit
- Louder than modern DC motor competitors (estimated 3-4 sones)
- Incandescent bulb not included; uses more energy than integrated LED units
6. Air King AK55L Combination Ceramic Heater with Exhaust Fan and Light
The Air King AK55L uses a self-regulating ceramic heating element that delivers 1350 watts of warmth. The ceramic element runs cooler than coil-type heaters, reducing the risk of overheating. The unit covers bathrooms up to 85 square feet with its 70 CFM fan, though the 5.0 sone noise level is the loudest in this roundup — think of a countertop microwave running nearby.
The build quality stands out. The heater blower wheel is a one-piece metal assembly that is electronically balanced, and the ventilation blower wheel is a one-piece polymeric design. This dual-wheel construction contributes to the unit’s durability. The moonstone glass lens is designed to withstand the heat from a 100W incandescent bulb without discoloring, and the lens flips down for easy bulb replacement.
Installation is more straightforward than many competitors because the housing is larger and easier to access. The 4-inch metal duct collar includes a backdraft damper. However, at 13 pounds, this is the heaviest unit in the group, and the grill dimensions (17.125 x 9.875 inches) require a larger ceiling opening than standard combo units.
Why it’s great
- Self-regulating ceramic heater runs cooler and safer than coil elements
- Durable metal blower wheel construction for long service life
- Flip-down lens makes bulb changes simple without removing the grill
Good to know
- Very loud at 5.0 sones — not suitable for noise-sensitive spaces
- Heavier and larger than most units; requires a bigger ceiling cutout
- Only 70 CFM limits effectiveness to small bathrooms
7. Broan-NuTone 162 Type IC Infrared Single-Bulb Ceiling Heater with Fan
The Broan-NuTone 162 is the most budget-friendly entry-level unit in this comparison. It uses a 250W R40 or BR40 infrared bulb (not included) for heat, which means the warmth is radiant rather than forced-air. This design heats the person or surface below the bulb rather than the room air, so it works best when you stand directly under it — ideal for a small vanity area or shower alcove.
At 70 CFM and 3.5 sones, the fan is louder than DC-powered competitors but adequate for a bathroom up to 70 square feet. The Type IC (Insulation Contact) rating means the housing can be safely covered with insulation, which is rare in this category and useful for energy efficiency in cold climates. The steel housing includes adjustable mounting brackets with keyhole slots for easier installation.
Installation is simple enough for a competent DIYer, especially as a drop-in replacement for older Broan models with the same footprint. Users report install times under one hour with attic access. The 4-inch round duct connector has tapered sleeves for a snug fit. Note that the heater function requires a separate light switch to operate independently from the fan.
Why it’s great
- Type IC rated — can be covered with insulation for better energy efficiency
- Compact steel housing fits standard ceiling cutouts; easy drop-in replacement
- Infrared heat provides instant warmth directly below the unit
Good to know
- Radiant heat only warms direct area, not the full room
- Heater bulb must be purchased separately (R40 or BR40)
- Noisier than premium competitors at 3.5 sones
