The Cozy is a smart insulating enclosure that is installed over existing radiators. When the system senses that a room needs heat, a quiet fan turns on to circulate warm air throughout the room. When the room is satisfied, the fans turn off, blocking overheating. Now you don’t have to open your windows anymore to stay comfortable!
Each Cozy measures room and radiator temperature (and steam traps in 2 pipe systems) and integrates a building's boiler controls. Note that the Cozy Control System does not fix existing boiler and radiator problems - proper system maintenance is required.
