The system for providing domestic hot water from a heat pump 1 includes a hot water storage tank 15. The tank has a hot water input 16 and a hot water output 17 near the top and a cold water input 19 and a cold water output 18 near the bottom. The domestic hot water supply 27 is separated from water supplied from the heat pump. The system includes a second heat exchanger 21 connected between the top and bottom of the tank which exchanges heat between water heated by the heat pump and the domestic hot water supply. The water flow of heated water from the heat pump through the second heat exchanger is matched to the flow of domestic hot water. The tank maybe stratified with a pair of funnels (Figure 4). |
