By combining an efficient impeller-style fan with a NiChrome heating element, the Wheater delivers instant heat in even the draftiest locations. For use with a wall thermostat or in-built thermostat. A powder-coated, surface-mounted wall-can may be purchased separately. When the W series is installed on a WSC surface can it add UL ratings for wet location applications?
