Vent-free heaters draw their air for combustion from the room in which they are installed. Pittsburgh Gas Grill and Heater Company provides them in either a clean burning blue-flame or an infrared radiant-plaque system. These vent-free heaters by Empire Heating Systems are 99.9% efficient with nearly all their radiant heat flowing directly into the room.
These vent-free gas heaters will continue to heat without electricity in case there is a power outage. They can be installed on a wall or onto your floor.
For safety, all of Empire’s vent-free heating systems include an Oxygen Depletion Sensor to automatically turn the heater off in the event that room oxygen levels drop to an unsafe level. Like all vent-free systems, Empire’s vent-free heaters are designed to provide supplemental not primary heat for your home.
