The Cozy is a thermostatic radiator enclosure that regulates the temperature of individual radiators in a steam or hot water (hydronic) heating system. The Cozy is a retrofit solution that can be installed on existing radiators without any modifications.
The Cozy enclosure has insulating material and fits over the existing radiator. The Cozy is equipped with a room temperature sensor, radiator temperature sensors, and a quiet fan. The room temperature sensor in the Cozy measures the temperature of the room and when the room temperature drops below the desired level, the fan turns on to allow heat to fill the room. As the temperature in the room reaches the desired level, the fan turns off.
To maximize energy efficiency in a building the Cozy must be deployed on at least 60% of the radiators. The Cozy is an energy-efficient solution that allows for precise temperature control, reduces over and under-heating, and can save up to 40% of emissions and heating costs.
