ABSTRACT OF THE DISCLOSURE A heat pump for use in heating or cooling residential, commer- cial or industrial buildings, industrial and agricultural processes and heating of water to moderate temperatures such as may be required in swimming pools or as a water pre-heater for any other use. The system includes a fuel consuming refrigerant boiler for producing a refrigerant in vaporized form at relatively high pressure, the output of the boiler being connected to a superheater and then to the primary jet of an ejector-type compressor. An evaporator unit exposed to ambient temperatures has its output line con- nected to an inlet of the ejector such that as the high pressure gaseous refrigerant flows through the nozzle of the ejector, a low pressure is created and the refrigerant from the evaporator is also caused to flow through the ejector compressor to a condenser where the refrigerant is allowed to give up its heat. The condenser is coupled in circuit with a receiver which holds liquid refrigerant and delivers same to the boiler and evaporator, all under control of fluid level or pressure sensitive switches governing the operation of a liquid refrigerant pumping means.
