The reservoir space further comprises one or more heat exchangers. Thereby heat is transferred from the flue gases from the flue gas duct 10 directly to the tank fluid and further through a heat exchanger to its heat transfer circuit, or the tank water is recycled directly to, for example, a radiator or underfloor heating element. The so-called waste heat taken from the flue gases can thus be transferred, for example, to floor heating and / or radiator heating or domestic hot water heating. The flue gas duct is preferably connected to a charging fireplace and preferably also to a wood-burning stove. Preferably, the fireplace comprises a heat exchanger mounted inside the masonry, whereby the water of the tank can be circulated through the heat exchanger of the fireplace in the tank. An electric resistor can also be used to heat the water in the tank in connection with the flue gas duct to a certain degree, for example by adjusting the thermostat. *: 20 pistons when the fireplace or woodburning stove is not in use. This ensures that the water in the tank always stays at a certain temperature. Preferably, the apparatus also comprises a hot water heating circuit. Thus, a separate boiler is not required, but the multifunctional barrel is made available for use as a so-called "storage tank", thus saving on the space required.
