Heat Pumps for Heating and Cooling Application 2 More advanced designs of air-source heat pumps can provide domestic hot water and space heating at the same time. The domestic hot water (DHW) is normally heated through some kind of heat exchanger allowing heat to be transferred from the heating water into the DHW. One way of doing this is to use a “tank in tank” – see the schematic below. Here the DHW tank is surrounded by the space heating water and therefore absorbs heat from the space heating water through the walls of the inner tank. The buffer tank is also provided to keep proper water volume inside the water system and to maintain water temperature at a constant level. It is sized at least 10% of minimum heating water volume flow rate required through the heat pump. A buffer tank is absolutely essential for air to water heat pumps to: • To allow the defrost cycle to happen • To allow supplementary heating • To improve the economy and efficiency of the system The return water is replaced with the fresh makeup city water. 21PDF Image | Heat Pumps for Heating and Cooling
