<p>A heating system such as a central heating system utilises as its heat source a heat pump which upgrade the heat of the return water flow from the radiators (1). A proportion of the return flow passes through a tank (5) containing the evaporator (14) of the heat pump and then enters a main tank (7) containing the compressor (19) and condenser (10) of the heat pump. Alternatively, the evaporator (13) may be located in the bottom of the main tank (7), surrounding the compressor housing (9).</p> |
