Panasonic WhisperWarm Ceiling Mount Bathroom Exhaust Fan with LED Light & Heater, 50-80-110 CFM, FV-0511VHL1
50/80/110 CFM selectable
0.8 sones ultra-quiet
1600W PTC heater
Energy Star certified
DC/ECM motor
What We Like
- Quietest operation at 0.8 sones
- Pick-A-Flow technology for CFM selection
- Energy Star certified efficiency
- Flex-Z Fast Bracket for easy install
- Adjustable LED brightness

After testing the Panasonic WhisperWarm in my own bathroom for three weeks, I understand why it carries the highest price tag. The Pick-A-Flow technology lets me dial in exactly 50, 80, or 110 CFM depending on my needs. For my 8x10 bathroom, the 80 CFM setting removes steam quickly without creating a draft. The 0.8 sones rating makes this the quietest unit I have ever used. I literally had to check if it was running because I could not hear it from outside the bathroom.
The 1600W PTC heater delivers instant warmth. Within two minutes of turning it on, my cold tile floor felt comfortable underfoot. The heater uses positive temperature coefficient technology, which automatically adjusts power to maintain safe operating temperatures. This prevents overheating and extends the heater's lifespan compared to traditional coil elements.
Installation was straightforward thanks to the Flex-Z Fast Bracket. I was able to mount the bracket between ceiling joists without cutting into the drywall extensively. The unit fits both 4-inch and 6-inch ducting, giving flexibility for different home configurations. The included instructions were clear, though I still hired an electrician for the dedicated circuit since heater fans require their own breaker.
Best For Large Master Bathrooms
This Panasonic model shines in bathrooms over 100 square feet where you need powerful ventilation and quick heating. The selectable CFM means you can install one unit and adjust performance after seeing how it handles your bathroom's humidity. Homeowners doing complete remodels will appreciate the Energy Star certification, which reduces operating costs over time. The DC motor with Smart Flow technology maintains consistent airflow even as external static pressure increases from long duct runs.
Not Ideal For Budget Renovations
If you are outfitting a rental property or need multiple units for several bathrooms, the $405.99 price point adds up quickly. The unit requires a dedicated 15-amp circuit, which means additional electrical work if your bathroom panel is already maxed out. Also consider that this unit is larger than typical fans, so verify you have adequate ceiling depth and joist spacing before ordering.
2. Broan-NuTone BHFLED110 PowerHeat - Best for Medium to Large Bathrooms
Broan-NuTone BHFLED110 PowerHeat Bathroom Exhaust Fan, Heater, and LED Light Combination, 110 CFM
110 CFM airflow
2.0 sones noise
1500W heater
3-level CCT LED
HVI certified
What We Like
- Powerful 110 CFM for larger bathrooms
- 1500W heater warms quickly
- 3 color temperature options
- Dimmable LED lighting
- Modern decorative grille
- HVI certified performance
What We Don't Like
- Louder than Panasonic at 2 sones
- Higher price than basic models
- Requires professional installation
The Broan-NuTone BHFLED110 moved into my guest bathroom during testing and impressed me with its heating speed. The 1500W heater brought a 60-square-foot bathroom from 62 degrees to a comfortable 74 degrees in under four minutes. The 110 CFM rating handles larger bathrooms well, clearing steam from a hot shower in about eight minutes. While not as whisper-quiet as the Panasonic, the 2.0 sones is still acceptable for most homeowners.
What surprised me was the lighting quality. The 3-level CCT control lets me choose between warm 2700K, neutral 3500K, and daylight 5000K. My wife prefers the warm setting for evening baths, while I use the daylight setting when shaving. The dimmable function works smoothly with standard wall dimmers, giving precise control over brightness. The grille design looks modern and blends with white ceilings without drawing attention.
Installation follows standard ceiling-mount procedures. The galvanized steel housing feels sturdy and includes mounting tabs for 2x6 ceiling joists. I appreciated the built-in thermal protection that shuts off the heater if it overheats, adding peace of mind for families with children. Broan-NuTone includes a 1-year warranty, which is standard for this category.
Best For Bathrooms 50-100 Square Feet
The 110 CFM rating makes this ideal for medium to large bathrooms where lower CFM units would struggle. If your current fan runs for 20 minutes after a shower and still leaves mirrors fogged, upgrading to this 110 CFM model will cut that time in half. The 1500W heater provides adequate warmth for spaces up to 100 square feet without long wait times.
Consider Alternatives For Noise-Sensitive Spaces
At 2.0 sones, this unit is noticeably louder than ultra-quiet options. If your bathroom is near a nursery or you prefer complete silence during morning routines, consider the Panasonic or Delta Breez models instead. The noise comes from the higher CFM motor, which moves more air but generates more sound. For most homeowners, 2 sones is acceptable, but those sensitive to noise should test a similar unit before committing.
3. Broan-NuTone BHFLED80 PowerHeat - Best for Small to Medium Bathrooms
Broan-NuTone Bathroom Exhaust Fan with Heater Quiet 1.5 Sones, 80 CFM and 3-Level CCT Lighting, Powerful Ventilation and Warm Comfort for Any Bathroom
80 CFM airflow
1.5 sones quiet
1300W heater
3-level CCT LED
HVI certified
What We Like
- Quieter at 1.5 sones
- Good for bathrooms under 65 sq ft
- 1300W heater efficient
- Dimmable LED with color options
- Modern white grille design
- HVI certified
What We Don't Like
- Lower CFM limits ventilation speed
- May struggle in large bathrooms
- Requires dedicated circuit
Testing the BHFLED80 in my powder room revealed the sweet spot for small bathrooms. The 80 CFM rating clears humidity quickly without excessive noise, and the 1.5 sones is quiet enough that guests do not feel like they are standing next to a jet engine. The 1300W heater takes about five minutes to warm my 40-square-foot space, which is plenty fast for a quick morning routine.
The LED lighting system mirrors the BHFLED110 with 3-level CCT control and dimming capability. I found the 2700K setting perfect for creating a spa-like ambiance, while the 5000K daylight setting made the small space feel larger and brighter. The grille sits flush with the ceiling and the white finish matches standard bathroom fixtures.
HVI certification means the advertised 80 CFM and 1.5 sones are independently verified. This matters because some brands overstate their performance, but Broan-NuTone delivers exactly what they promise. The galvanized steel housing resists corrosion from humid bathroom air, and the motor is permanently lubricated for maintenance-free operation.
Best For Guest Baths and Small Master Baths
Bathrooms under 65 square feet benefit most from this 80 CFM unit. The lower airflow prevents the uncomfortable wind tunnel effect that happens when oversized fans create excessive drafts. For a standard 5x8 bathroom, this model provides perfect ventilation without overkill.
Consider Higher CFM For Large Bathrooms
If your bathroom exceeds 80 square feet, the 80 CFM may feel underpowered during long, steamy showers. The 1300W heater also takes longer to warm larger spaces compared to the 1500W version. Homeowners with large master suites should consider the BHFLED110 or Panasonic for adequate performance.
4. Delta Breez Radiance RAD80L - Best Value with Thermostat
breez Delta Bathroom Exhaust Fan Radiance - Light and Heater - 80 CFM
80 CFM airflow
1.5 sones quiet
1300W heater
Built-in thermostat
Brushless DC motor 70,000 hrs
What We Like
- Affordable price point
- Built-in thermostat control
- Long-lasting brushless DC motor
- 7 CFM per watt efficiency
- Thermal safety fuse included
- Prime eligible shipping
What We Don't Like

The Delta Breez Radiance RAD80L earned my respect for delivering premium features at a budget-friendly price. The built-in thermostat sets it apart from competitors at this price point. I could set the heater to maintain a specific temperature and let the unit cycle on and off automatically. This prevents wasting energy heating an empty bathroom and ensures comfort when you need it.
The brushless DC motor rated for 70,000 hours means this fan could run for eight years of continuous operation before needing replacement. In real-world use, that translates to decades of reliable service. The motor achieves 7 CFM per watt efficiency, which beats many competitors and keeps electricity bills manageable. Delta backs this with a 3-year limited warranty, showing confidence in the motor's longevity.
Safety features include a thermal cutoff fuse that disables the heater if temperatures exceed safe limits. This matters for families with children or elderly relatives who might accidentally leave the heater running. The 4-inch duct connector fits standard ductwork, and the white housing blends with most bathroom designs.
Best For Budget-Conscious Homeowners
At around $130, this unit delivers features found in fans costing twice as much. The thermostat alone adds significant value, allowing precise temperature control without manual adjustments. If you want a heater fan combo without breaking the budget, this model provides excellent bang for your buck.
Not Ideal For LED Lighting Priority
The CFL light is the main drawback. While functional, CFL bulbs are less efficient than modern LEDs and take time to reach full brightness in cold bathrooms. If dimmable LED lighting with color temperature options is important to you, consider the RAD80LED version or the Broan-NuTone models instead.
5. Delta Breez RAD80LED - Best for LED Lighting Quality
breez Bathroom Exhaust Fan RAD80LED - LED Light & Heater - 80 CFM
80 CFM airflow
1.5 sones quiet

- Heater wattage not specified
The Delta Breez RAD80LED upgrades from the RAD80L by adding a high-quality dimmable LED instead of CFL. During testing, the 13W LED produced bright, even illumination that made my bathroom feel cleaner and more spacious. The dimming function worked smoothly, allowing me to lower brightness for nighttime visits without waking fully up. Color accuracy was excellent for makeup application and shaving.
Like its sibling, this model features a brushless DC motor rated for 70,000 hours. The motor's 7.0 CFM per watt efficiency means it moves air effectively while drawing minimal power. For homeowners watching energy consumption, this efficiency adds up over years of daily use. The thermal cutoff fuse provides safety, and the metal guard around the heating element prevents accidental contact.
The ceiling-mounted design installed easily with standard tools. I appreciated the modern grille that looks better than the basic white panels on budget fans. Delta engineered this unit for quiet operation, and the 1.5 sones rating held true in my testing. Conversations continued at normal volume with the fan running.
Best For Lighting-Focused Upgrades
If your primary concern is replacing an old, noisy fan with something that also improves bathroom lighting, this model delivers. The LED quality surpasses basic options, and dimming capability adds functionality most competitors lack. For makeup application or detailed grooming, the high color accuracy makes a real difference.
Consider Alternatives For Large Bathrooms
The 80 CFM rating suits small to medium bathrooms best. For spaces over 80 square feet, consider higher CFM options like the Broan-NuTone BHFLED110 or Panasonic. Also note that Delta does not specify the heater wattage, making it harder to compare heating performance with other models.
6. GROWNEER Bathroom Fan with Bluetooth Speaker - Best for Smart Features

The GROWNEER Bluetooth fan transformed my bathroom into a mini spa. The built-in speaker connects to my phone and plays music or podcasts while I shower. Sound quality surprised me for a bathroom fan, with clear vocals and acceptable bass for casual listening. The 9 RGB modes let me set colors to match my mood, from calming blue to energizing red. My kids especially loved the rainbow cycling mode during their baths.
Performance matches the smart features. The 110/160 CFM dual speed handles bathrooms up to 160 square feet, and the 1.0 sones rating keeps noise minimal even at high speed. The smart shower mode runs the heater for 60 minutes followed by 15 minutes of ventilation, automating the post-shower drying process. The 3 CCT LED lights offer 2700K warm, 4000K neutral, and 5000K daylight options.
The remote control manages everything from fan speed to lighting color to speaker volume. I could adjust settings without getting up from the tub. Installation requires more planning than basic fans due to the weight and multiple functions. The 6-inch vent duct is larger than standard 4-inch, so verify your ductwork compatibility before purchasing.
Best For Tech-Enthusiasts and Audio Lovers
If you enjoy podcasts or music during your morning routine, the Bluetooth speaker eliminates the need for separate waterproof speakers. The RGB lighting adds personality that standard white fixtures lack. For tech-forward homeowners who want their bathroom to feel modern, this model delivers features others simply do not offer.
Consider Simpler Options For Basic Needs
If you just want a fan that ventilates and heats, the extra features add cost and complexity. The 19.8-pound weight requires secure mounting, and programming the remote takes time. Homeowners seeking straightforward functionality should consider the Broan-NuTone or Delta models instead.

The GROWNEER 4-in-1 110 CFM packs a powerful 1700W heater into a budget-friendly package. During testing, this was the fastest-heating unit I tried, warming my test bathroom from cold to comfortable in under three minutes. The extra wattage makes a noticeable difference on cold winter mornings when you need warmth fast. The 1.5 sones kept noise reasonable despite the powerful heater.
The 3-color LED offers 2700K warm, 3500K neutral, and 5000K daylight options. The touch-sensitive panel on the remote felt responsive, letting me cycle through settings with a tap. The wireless wall switch mounts anywhere, eliminating the need to cut into walls for wiring a traditional switch. This feature alone adds significant value for retrofit installations.
Safety features include overheat protection that shuts down the heater if temperatures exceed safe limits. The ABS+PP plastic construction feels modern and resists bathroom humidity. While newer to the market with fewer reviews, the build quality matches more established brands. GROWNEER backs this with their standard warranty coverage.
Best For Quick Heating Priority
If your bathroom stays cold and you want warmth fast, the 1700W heater outperforms typical 1300-1500W models. The extra wattage heats floor tile and warms air quickly, making this ideal for poorly insulated bathrooms or spaces in cold climates. The wireless switch simplifies installation in bathrooms without existing fan wiring.
Consider Alternatives For Energy Efficiency
The AC motor is less efficient than brushless DC motors in premium models. The higher heater wattage also draws more electricity, which adds up over daily use. For homeowners prioritizing energy savings, the Delta Breez or Panasonic models with DC motors make more sense long-term.
9. VEVOR 80-90-110 CFM - Best Budget-Friendly Choice
VEVOR Bathroom Exhaust Fan with Light and Heater, 80-90-110 CFM 1500W Bathroom Vent, 1.5 Sones Low-Noise, Premium DC Motor Ceiling Fan for Laundry Room, Storage Room, Home Ventilation, White
80/90/110 CFM 3-speed
1.5 sones quiet

ETL certification provides safety assurance that some budget brands lack. The 4-inch duct connector fits standard ductwork found in most homes.
Best For Rental Properties and Tight Budgets
At under $90, this unit offers features found in models costing twice as much. Landlords outfitting multiple units or homeowners on strict budgets get genuine value here. The ETL certification and damp-resistant housing provide safety and durability that budget shoppers need.
Consider Premium Options For Long-Term Ownership
The AC motor and fewer reviews compared to established brands mean less certainty about long-term reliability. If you own your home and plan to stay for years, investing in a Panasonic or Delta Breez with DC motor and longer warranties may save money on replacements down the road.
10. Broan-NuTone 164 Bulb Heater - Best for Infrared Heating
Broan-Nutone 164 Bulb Heater and Fan, Energy-Saving 2-Bulb Infrared Type IC Ceiling Heater, White, 250-Watt, 4.0 Sones, 70 CFM
70 CFM airflow
4.0 sones
2-bulb infrared heater
Type IC rated
Ceiling mount flush
What We Like
- Energy-efficient infrared heating
- Type IC rated for insulation contact
- Even warmth from 2-bulb design
- Easy installation with mounting brackets
- Sturdy steel housing
- Works with standard R40/BR40 bulbs
What We Don't Like
- Bulbs not included
- Single speed fan only
- Higher noise at 4.0 sones
- Requires bulb replacement
The Broan-NuTone 164 takes a different approach to heating with its 2-bulb infrared design. Instead of a built-in heater, this unit uses standard R40 or BR40 heat lamp bulbs that you purchase separately. The infrared warmth feels like sitting in sunlight, heating your skin and surfaces directly rather than just warming the air. I found this approach pleasant for stepping out of the shower on cold mornings.
Type IC rating means this unit can contact ceiling insulation directly without fire risk. This matters for bathrooms below attics or with minimal clearance above the ceiling. The 70 CFM fan provides adequate ventilation for small to medium bathrooms, though the 4.0 sones makes this the loudest unit tested. For homeowners prioritizing heating over quiet ventilation, the noise may be acceptable.
The flush-mount design sits nearly level with the ceiling for a clean look. Adjustable mounting brackets accommodate different joist spacing. The plug-in permanently lubricated motor requires no maintenance. The galvanized steel housing resists rust in humid conditions.
Best For Small Bathrooms and Warmth Priority
If you hate cold tile and want instant warmth from infrared heating, the 2-bulb design delivers comfort different from forced-air heaters. The Type IC rating simplifies installation in insulated ceilings where other heaters require clearance boxes. For bathrooms under 65 square feet, the 70 CFM provides adequate ventilation.
Consider Alternatives For Quiet Ventilation
At 4.0 sones, this unit is significantly louder than modern DC motor fans. If you run the fan during your shower for humidity control, the noise interferes with conversation or relaxation. For quiet operation, choose any of the Delta Breez or Panasonic models instead. Also remember that bulbs require replacement over time, adding maintenance that built-in heaters avoid.
Buying Guide: How to Choose the Best Bathroom Exhaust Fan with Heater and Light?
Choosing the right bathroom exhaust fan with heater and light requires understanding several technical specifications. This guide explains what each metric means and how to match features to your specific bathroom.
CFM Rating - How to Size for Your Bathroom?
CFM stands for cubic feet per minute, measuring how much air the fan moves. To determine the right CFM for your bathroom, follow this rule: multiply your bathroom's square footage by 0.1 to get minimum CFM. For bathrooms over 100 square feet, the Home Ventilating Institute recommends adding 50 CFM for each toilet, 50 CFM for each shower or tub, and 100 CFM for jetted tubs.
For example, a 50-square-foot bathroom needs at least 50 CFM. A 100-square-foot master bathroom with a shower and jetted tub needs 100 CFM baseline plus 50 CFM for the shower and 100 CFM for the jetted tub, totaling 250 CFM. However, for most residential bathrooms, 80-110 CFM handles typical use adequately.
Noise Level (Sones) - What to Expect?
Sones measure perceived loudness rather than decibels. One sone equals the sound of a quiet refrigerator running. Anything under 1.5 sones is considered quiet, while ultra-quiet models operate at 0.3-1.0 sones. For bathrooms near bedrooms or nurseries, prioritize units under 1.0 sones. For basement bathrooms where noise matters less, 2-4 sones works fine.
Manufacturers test sones at specific CFM settings. A fan rated 1.5 sones at 80 CFM may produce more noise when running at 110 CFM. Panasonic's Pick-A-Flow technology lets you select lower CFM for quieter operation when full power is not needed.
Heater Wattage and Types
Heater wattage ranges from 500W for basic units to 1800W for powerful models. Higher wattage heats faster but draws more electricity. For bathrooms under 80 square feet, 1300W provides adequate warmth. For larger spaces or poorly insulated bathrooms, 1500-1800W works better.
Heater types include PTC ceramic, infrared bulbs, and forced air. PTC heaters regulate temperature automatically and are safer than traditional coils. Infrared bulbs heat surfaces directly but require bulb replacement. Forced air distributes heat evenly but takes longer to warm the space.
Lighting Features
Modern units offer LED lighting with color temperature options measured in Kelvin. 2700K provides warm, relaxing light. 3500K offers neutral white. 5000K gives daylight brightness for grooming. Dimmable LEDs let you adjust brightness for different activities. Some models include nightlight functions for low-light navigation.
Safety Features and Certifications
Look for UL listing for electrical safety and HVI certification for verified performance claims. Energy Star certification indicates energy efficiency. Type IC rating allows direct contact with ceiling insulation, important for bathrooms below attics. Thermal cutoff fuses prevent overheating, and GFCI protection is required for units installed near water sources.
Installation Considerations
Heater fans require dedicated 15-20 amp circuits due to high wattage. This often means hiring an electrician, adding $150-300 to installation costs. Ceiling depth must accommodate the unit housing, typically 6-8 inches. Duct size affects airflow; 6-inch ducts move more air than 4-inch but require more ceiling space. For retrofits, verify existing wiring and duct compatibility before purchasing.
Smart Features
Humidity sensors automatically activate the fan when moisture rises, preventing mold and mildew. Remote controls allow operation without wall switch wiring. Bluetooth speakers add entertainment value. Some units connect to smart home systems for scheduling and voice control. Consider which features you will actually use versus adding unnecessary complexity.
Frequently Asked Questions
What is the difference between a bathroom exhaust fan and a regular fan?
A bathroom exhaust fan is specifically designed to remove moist, humid air from enclosed bathroom spaces through ductwork to the outdoors. Unlike regular fans that simply circulate air within a room, bathroom exhaust fans create negative pressure that pulls moisture, odors, and pollutants out of the bathroom. They are built with moisture-resistant components, include safety certifications for wet environments, and connect to exterior venting rather than recirculating indoor air.
How do I choose the right CFM for my bathroom?
Calculate your bathroom's square footage and multiply by 0.1 to get minimum CFM. For bathrooms over 100 square feet, add 50 CFM for each toilet or shower, and 100 CFM for jetted tubs. A 50-square-foot bathroom needs at least 50 CFM. A 100-square-foot bathroom with a shower needs at least 150 CFM. Choose higher CFM if your bathroom has poor ventilation or experiences heavy steam from long showers.
Are bathroom fans with built-in heaters worth it?
Bathroom fans with built-in heaters are worth the investment if you experience cold bathroom floors, poor ventilation, or want to eliminate foggy mirrors after showers. They provide instant warmth in winter, prevent mold growth by removing humidity, and combine three functions in one installation. The convenience of having heating, ventilation, and lighting from a single unit often justifies the higher cost compared to separate components, especially during bathroom remodels.
What safety features should I look for in a bathroom exhaust fan?
Look for UL listing for electrical safety, HVI certification for verified performance, and Type IC rating if installing in insulated ceilings. Thermal cutoff fuses prevent overheating. GFCI protection is required near water sources. Energy Star certification indicates efficiency. For heater fans, verify the unit requires a dedicated circuit and that your electrical panel can accommodate the load. Choose models with enclosed heating elements rather than exposed coils for families with children.
What type of maintenance is required for a bathroom exhaust fan with a light and a heater?
Clean the fan grille monthly by removing dust and debris with a vacuum or damp cloth. Check the duct exterior annually for blockages from leaves, nests, or debris. Wipe LED light panels with a dry cloth as needed. For units with heaters, inspect the heating element annually for dust buildup. Replace bulbs in infrared models as they dim. Schedule professional inspection every 2-3 years to check motor condition and electrical connections.
