Electric infrared ceiling panels TEPLIY KVADRAT are low-temperature radiants for efficient heating of residential & office premises up to 4 m high. The system is based on principle of thermal infrared radiation. The advantage of transferring heat by radiation is the immediate effect of heating surfaces of objects that absorb heat from the panels, without preheating the air around them. Thus, all objects in the premises are heated, including floor, walls, furniture, equipment, etc. The heated objects emit heat secondary and give it to the air by means of convection. So, the system provides fast room heating, has low lag effect in comparison with any convective systems. Low temperature of heat distribution creates uniform temperature in the room. TEPLIY KVADRAT panels are designed for comfortable and energy-efficient heating of any kinds of rooms, except rooms with high humidity. The panels can operate directly from the socket or standard thermostat-controller.
