FIELD: engines and pumps.
SUBSTANCE: external combustion engine generates electric power in heating by burner. Secondary boiler produces hot water and is arranged on Stirling engine and provided with heat exchanger of apparent heat and that of latent heat. Stirling engine head wherefrom waste gas escaped after engine heating is communicated via channel with heat exchanger of latent heat. Waste gas flowing from top of heat exchanger of latent heat to its top participates in heat exchange. Said channel is made integral with inner surface of the casing accommodating heat exchanger of latent heat.
EFFECT: higher thermal efficiency.
