Investigation of heating ability of tubular-type radiation water heater using average monthly data for summer period

The advantages of the radiation life-support systems include the use of a renewable energy source, noiselessness, and the absence of harmful emissions into the atmosphere during the conversion of solar radiation into other forms of energy. One of the promising types of such life-support systems are tubular-type radiation solar heaters, which have the best price/ quality ratio. In the northern regions and in Siberia, the use of radiation heating systems in the cold season can significantly save on heating buildings, and in the offseason to completely abandon the use of organic fuels and electricity. The use of modern technologies and heat-insulating materials in the construction of buildings allows the use of solar radiation heating systems, both for heating and water heating for hot water supply of cottage-type buildings without additional energy sources.
