A delivery set (HIU) is a component of the energy system in your home, containing at least a heat exchanger. The HIU facilitates the transfer of energy between the central system and the system within the home.
HIUs come in various types and sizes. Typically, the HIU is installed in the meter cupboard or technical room of a residence. From the HIU, pipes extend to, for example, underfloor heating or a hot water tap.
