TECHNICAL COMPARISON OF INFRARED LONG WAVE HEATERS

In the work, a technical comparison of three samples of long-wave infrared, ceiling heaters of Ukrainian production by the firms Bilux, Teplov, Teplotema, with a rated power of 600 W. It was found that the Bilux heater has the lowest heat losses due to the body, and the temperature conditions of the device indicate reliable operation during prolonged use at maximum power. Teplov and Bilux can be compared as follows: Teplov has lower losses through the housing from above and higher from the side, so in balance they are the same in terms of heat loss. The Teplotema heater is the least reliable and has the highest heat loss through the housing. According to the thermal track, the Bilux heater is the most efficient, and Teplov is the least efficient. According to the efficiency calculation, Bilux heaters are 68% more efficient than Teplov heaters, and 19% more efficient than Teplotema heaters.
