Heat at the speed of light! No matter what climate you live in, no one likes to step out of a warm shower or tub into a chilly bathroom! But turning up the heat just to warm up the bathroom is not energy efficient. Aero Pure's 2- and 4-bulb Very Quiet Fans with heat and light deliver immediate warmth when you step out of the shower and quietly clear the bathroom of excess moisture. The extra wide heat lamps keep your bathroom warmer with fewer cold spots. All Aero Pure Very Quiet Heater Fans are installation-friendly and come standard with mounting brackets, vibration-dampening rustproof steel housing, a back draft damper, easy maintenance grilles, a multi-function switch, a full four-year warranty, and include 2 or 4 anti-blast infrared 16 Series heat lamps and a 60W incandescent bulb. The fan, light, and heater may be wired separately. 716 Series requires a dedicated 10-amp circuit.Take the chill out of your bathroom!
