FIELD: engines and pumps.
SUBSTANCE: water boiler with built-in heat pump relates to hot water boilers production, using latent heat in flue gases, and contains main heat exchanger, combined with furnace, additional heat exchanger with parts of at least one heat pump evaporators, which condensers are able to transfer heat for heating of rooms, wherein main and additional heat exchangers are connected in one housing. Thus enabling compactness of boiler - heat pump system, ease and simplicity of installation, providing coordinated operating modes of boiler and heat pump with provision of highly efficient of boiler and heat pump combined operation.
EFFECT: at variation of boiler thermal performance device efficiency can greatly exceed condensation boiler efficiency.
