Empire Heating Systems Vent-Free Room Heaters
Vent-Free systems draw room air to support combustion in a clean-burning blue-flame or radiant-plaque system. Rated at 99.9 percent
efficient, vent-free heaters release nearly all of the available heat energy into the room.
To ensure safe operation, all vent-free systems include an Oxygen Depletion Sensor (ODS) to automatically turn off the heater if room oxygen level drops to an unsafe level.
Vent-free systems are designed to provide supplemental heat and may not be used as a primary heat source.
