A heat pump for heating or cooling dwelling houses or like confined spaces includes a refrigerant circuit which comprises a compressor (1), a first heat-exchanger (7) thermally connected to a heat source, a second heat-exchanger (4) thermally connected to a fan system, a third heat-exchanger (2) thermally connected to a tap hot-water system (11, VV), an expansion valve (5) and a two-position refrigerant flow reversal valve (3). The valve (3) is operative to reverse the flow sequence between the various units in the refrigerant circuit, depending on whether the heat pump is to produce heat or cold. Irrespective of whether the heat pump is intended to deliver heat or cold, it can be caused, at the same time, to produce hot tap water or to maintain the temperature of the water without needing to interrupt prevailing heating or cooling of the rooms or spaces concerned. This is made possible by heating the tap water directly in the third heat-exchanger (2) and by causing the tap water to pass through control apparatus in the form of a circulation pump (8) and a valve (9), or a shunt (10) which bypasses the valve, during its passage from the third heat-exchanger (2) to the tap water network (VV).
