Average tasks like showering, bathing and shaving can put home-harming humidity into the air in your New Castle home. There’s good news still—a straightforward bathroom ventilation fan can keep you from warped wood, mold growth, broken drywall and other trouble connected with a humid bathroom.
Even if you have ventilation fans in your bathrooms, do you know if they’re the proper size? Are they as quiet and energy efficient as they could be? Central Heating & Plumbing is here to answer your questions.
Today’s bathroom ventilation fans are small and modern and they operate more quietly and economically than ever before. You’ll find a great range of choices, from classic fans that will get the job done to fans with integrated heat lamps, motion sensors and heat-exchanger ventilation that helps prevent warmed air from escaping through your ventilation. While you have a lot of bells and whistles to pick from, the most critical aspect of your fan is whether or not it’s large enough to do its job.
Rated by the cubic feet per minute (CFM) of air they push, a bathroom ventilation fan should be able to exchange the air in a bathroom at least eight times an hour. With a standard 8-foot ceiling, your ventilation fan should have a CFM rating about the number of square feet in your bathroom. Thus, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be sufficient.
If you have a higher ceiling, the equation gets a little more complicated. You’ll want to multiply the width of the room by its height and length, divide it by 60 and multiply by 8. Or, to keep it easy, you can use HGTV’s advice for bathrooms larger than 100 square feet – establish your CFM requirements by increasing 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
