In the heating season, it allows the DHW heating tank and the space heating tank to be maintained each at a separate temperature (\u003cem\u003elower temperature for the space heating tank\u003c\/em\u003e). This reduces the power consumption of the heat pump since its power draw decreases when its hot water supply temperature decreases. In the summer season, the above installation with 2 tanks allows the heat pump to produce chilled water for space cooling (Tank T-02) and DHW hot water (Tank T-01). The priority between the two tanks can be selected in the menu of the HP controller.\u003c\/p\u003e\n\u003cp\u003eIn projects where Operating Space Heating temperature is close the DHW heating one and\/or no cooling in the project, one buffer tank can be used:\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0010\/8458\/8093\/files\/Capture1_58ae9711-469f-40cb-ab9a-389b626fdb3b.png?v=1718204917\"\u003e\u003c\/p\u003e\n\u003cp\u003eIn the above configuration, a buffer tank with indirect coil is needed.
