Williams floor furnaces use no above-the-floor room space as it unobtrusively and efficiently circulates warm air, and does it without the aid of a blower. These models are fitted with an automatic floor-register grill temperature control and non-electric pilot to ensure continuous heat - even during power outages.

Floor furnaces operate very quietly.These models offer affordable solutions for limited-space floor plans, remodels, remote cabin locations and new construction.

In order to operate on LP gas, a separate conversion kit must be purchased. (Please see the Accessories tab above.) Please read this Important Safety Notice.
