Williams Ventless Gas Heaters

Our wall-mounted ventless gas heaters do not require any ductwork or chimneys. You can equip our ventless propane heaters with an oxygen depletion sensor for extra safety. These non-electric, ventless propane heaters offer an easy push-button ignition and either manual or automatic controls. The natural gas, propane, or fuel exchange systems equipped in these wall-mounted ventless gas heaters provide up to 99.9% efficiency and come in infrared or blue-flame models.
