The invention involves a tap water structure for storing and heating tap water. The tap water structure contains storage devices, such as a tap water storage tank, for storing a certain amount of tap water. The storage devices are equipped with a tap water input for adding tap water to the storage devices, as well as a tap water output for removing water from the storage devices. The tap water structure is equipped with heating elements that will warm the tap water stored in the storage devices. The storage devices also include a heat exchanger supply and a heat exchanger return, as well as an additional heat exchanger return; these can all be connected to an external heat exchanger unit. The tap water device includes regulators to return the tap water to the storage devices either via the heat exchanger return and/or via the additional heat exchanger return.
