The results of the research of energy economic efficiency of variable operation modes of energy supply systems (ESS) with peak sources of heat (PSH) and cogeneration heat pump installations (CHPI), using the heat of the industrial and natural sources are presented in the given research, they enable to provide the substantiated determination of energy efficient and economically efficient operation modes of ESS with CHPI and PSH with the combined seasonal usage of low-temperature heat of industrial and natural sources. We suggest the results of the research on the example of ESS with CHPI and PSH for thermal scheme of the health resort boiler house. In our study the application of energy efficient and economically expedient variant of energy supply system with CHPI, based on steam-compressor heat pumps and gas-piston engines-generators (GPE) was suggested in order to improve the operating indices of the thermal scheme of the health resort boiler house. In the study the combined seasonal usage of the boiler house waste flue gases heat in CHPI was foreseen with the usage of utilization equipment as well as the natural heat of the surface waters. It is determined that under the conditions of variable operation modes of ESS with CHPI and combined seasonal usage of the heat of the industrial and natural sources in CHPI, the most efficient by energy, economic and technical indices is the variant of ESS with CHPI application in the thermal scheme of the health resort boiler house with the utilization of 50% of the thermal power of the boiler house waste f gases in utilization equipment and CHPI. If this variant of ESS with CHPI and PSH is used, then energy efficient and economically substantiated operation modes of ESS with combined seasonal usage of low-temperature heat of the industrial and natural sources will be provided. The approach, suggested in the given paper, concerning  the study of energy economic efficiency of variable operation modes of ESS with PSH and CHPI, using low-temperature heat of the industrial and natural sources, enabled to provide the substantiated definition of energy efficient and economically efficient operation modes of ESS with CHPI and PSH with the combined seasonal usage of low-temperature heat of the industrial and natural sources.
