"The article presents the results of creating a low-cost heat recovery system on the example of ""light"" of the gas infrared emitter by changing a single-layer thin-walled reflector to reflector upgraded on the principle of ""water jacket"" and the results of testing the effectiveness of modernized design on a specially designed stand. As a result, it was concluded that the streamlined design of the reflector gas infrared emitter will minimize the loss of heat towards the ceiling of the building and to avoid condensation on the inner surface of the roofs, a violation of the thermal regime, and as a consequence of premature failure of the roof and walling. In addition, through the use of exhaust heat for heating the coolant (water) flowing through a modernized reflector increases the efficiency of the system of gas infrared heating by 10%."
