Heat accumulator, preferably for a hot water central heating system

摘要

Heat accumulator, preferably for a hot water central heating system. In the container (1) of the heat accumulator, there is arranged, in addition to an electric heating device (5), a combustion chamber for solid and/or liquid and/or gaseous fuels. If sufficient electrical energy is not available, heat can be generated in the combustion chamber by combustion of fuel. The accumulator container can also contain a heat exchanger (7) for supplying heat, e.g. solar heat. A heat exchanger (8) for heating service water can also be present. The arrangement of a combustion chamber (6) directly in the accumulator container has the advantage, in relation to a system with a separately installed heating boiler, that the installation of a system for mixed operation is considerably simplified.
