A shower 18 is provided with heated water with part of its heat derived from waste heat. The waste heat results from the water after it is used in the shower. A heat exchanger is mounted below the shower and cold water is suppled through a pipe 36 to a combined heater and pump unit 14. The hot waste water exits a shower tray 34 at drain 40 and circulates around the cold water pipe to transfer heat to it before it is discharged. The pipe 36 may be coiled, serpentine, or bent to be accommodated within the shower tray. The heat exchanger may alternatively be located below a bath or hand basin or in washing machines, dishwashers, or multi occupation buildings to perform the same waste heat recycling function. |
