Williams Gas Heater 17735 Series gas wall heaters gain their efficiency and versatility by being Gas Fired Forced Draft Heaters. These heaters operate by forcing outside air through the intake pipe and heating it inside the unit. “Whispersmooth” fans then quietly radiate the heat throughout the room. Combustion takes place in an airtight, sealed chamber which is completely isolated from the room, providing total safety. And because the combustion is gas fired, these heaters provide a greater economy than electric heaters. Combustion exhaust is then safely discharged to the outside through the same vent as the intake. The Unique Humidification System allows you to add water so you can keep moisture in winter's dry air.
