Definitions

• the invention relates in general to the field of heat control system, in particular heat control systems comprising a heat pump, in particular a hybrid heat pump.
• the present invention relates to appendage technology and structure for a heat control system.
• the present invention relates to a connecting assembly for fluidly coupling a heat pump with at least one of a heat release system and a heating boiler, to a method of reducing heat leakage, to a method of increasing installation efficiency, to a heat control system, and to a method of pumping heated fluid through a heat control system.
• Heat control systems generally comprise at least a type of heat supply and a heat release system. Heat may be provided by heating a fluid, such as water, and to transfer the heated fluid through the heat release system. Heating the fluid, and providing heated fluid to the heat release system, can be done by a heat pump. Such heat pump is able to transfer heat from a cool space to a warm space by transferring thermal energy using a refrigeration cycle, cooling the cool space and warming the warm space.
• a heat pump can exist comprising an outdoor unit and an indoor unit. The heat pump's outdoor unit extracts heat from the outside air and transfers it to the indoor unit via pipes with a refrigerant. The indoor unit emits heat to the water of the heating system.
• a special type of heat pump is the hybrid heat pump.
• a heating boiler is involved in the heat control system. Heat supplied to the heating boiler is used for heating tap water. The amount of heat produced by the heat pump does not always match the heat demand. Doing nothing with that excess heat is not efficient and therefore a storage tank or buffer tank can be installed between the heat pump and the central heating system, to store excess hot water for use when needed again.
• the amount of appendages has become a major challenge when it comes to the available space where the different elements of the heat control system have to be connected to each other, such as with connecting pipelines from the heat pump to either or both the heat release system and the heating boiler, to and from the buffer tank, a bypass valve may additionally be involved, and more or other elements.
• the buffer tank with the different types of appendages as described around it requires a lot of space and complexity in the room, in a place where in practice space is relatively limited. It further requires a lot of time as well as skills from the installer to get such complex structures installed. Installation processes therefore in general lead to the so-called commonly known 'spaghetti-structure' installations.
• this concerns pipelines and coupling elements and may further comprise insulation material and a bypass valve. These elements must be individually placed in the usually limited space and must be mounted along and around each other, which is time and skills consuming.

• Such systems may in particular be heating systems such as heating radiator systems.
• heating boiler refers to known boiler system such as heat only boilers or regular boilers or combi boilers, made up of multiple components, such as the gas boiler unit and with or without a water tank which is able to store heated water for a period of time.
