WhisperWarmDC FV-0511VH1 50-80-110 CFM, Ceiling Mount Fan/Heater

Indoor comfortability is becoming more important in today’s environment. WhisperWarm DC provides easy code compliance for the professional, while the homeowner/occupant enjoys a warmer, more comfortable and HEALTHIER environment, with enhanced heating technology that quickly heats up any bathroom.  WhisperWarm DC does a great job if you live in an older home and there's no heat at all in the bathrooms; or if you run an assisted living facility and want to provide extra comfort to your residents; or you're a residential remodeler looking to squeeze extra value into a bathroom, W Warm DC is the solution!  

Installed Performance guarantees up to .375” w.g. static pressure and certified quiet operation at 0.25" w.g. static pressure

Although ASHRAE, ENERGY STAR®, LEED for Homes, and HVI have set the industry standard for performance measurement at 0.1” and 0.25" w.g., WhisperWarm DC fan/heaters not only provide the powerful CFM output at 0.375" w.g. that is more representative of most installations.  Sones have also been certified at 0.25" w.g.*



ECM Motor- Best Performing, Most Energy Efficient Motor Available

WhisperWarm DC fan/heaters features the same revolutionary ECM motor that comes with our WhisperGreen line of products. With built-in SmartFlow™ technology, WhisperWarm DC fan/heaters are designed to perform as rated, providing precision ventilation. When the fan senses static pressure, its speed is automatically increased to ensure optimal CFM output. This feature provides peace of mind, as the installer doesn’t have to worry about compromising the fan’s performance, even with a complicated duct run. 


Warm DC ECM Motor

High-Tech PTC Heating Element

1600W Positive Temperature Coefficient (PTC) heater provides greater safety and reliability.  They are self-limiting, which means that as they approach their design operating temperature, electrical consumption is automatically decreased, which prevents them from overheating. 


Warm DC Heater

Low-profile Grille with Built-In Diffuser

The unique, adjustable grille with built-in diffuser and directional louvers produces higher output velocity for dispersing and directing warm air faster and wider.

Warm DC Grille

Pick-A-Flow® Airflow Technology – You Choose The CFM

Built-in Pick-A-Flow® Airflow Selector provides the unique ability to select your required airflow (50-80-110 CFM) with the simple flip of a switch. Being able to choose the proper CFM level gives you the flexibility and assurance that one fan will satisfy a range of ventilation design requirements and perform as promised, even with a complicated duct run.

Fast, Flexible and Easy Installation

The Flex-Z Fast™ Installation Bracket with single-hinge articulating joints to easily position bracket in between the joist and/or through ceiling hole installs the fan exactly where you want it, in old or new construction. WhisperWarm DC incorporates an integrated dual 4 in. or 6 in. duct adapter to give you flexibility in duct layout and design. For short runs, you can go with a smaller duct size, but long runs are OK too - just move up to the 6 in. duct. Also fits in 2 x 8 construction.  anasonic fans are UL listed for tub/shower enclosure (just install them on a GFCI-protected circuit). With these great features, your installation options open up.
