Overview for Williams 4505622A

The Williams floor furnace takes up no above-the-floor space and effectively circulates warm air without the aid of a blower. The floor furnaces are fitted with an automatic floor register grille temperature control and a nonelectric pilot to make sure you have continuous heat even during power outages. Williams floor furnaces circulate heat through natural convection and are the perfect choice for homes with limited space.
