Modular water e.g. pure water, heat accumulator for storing heat energy in heating system for central heating- and/or hot water supply, has complementary guide including ring shaped guide rail and counter guide

摘要

The accumulator (01) has a heat source for supplying heat energy. Heat energy from the accumulator is extracted from heat flow of a heat exchanger (11). The heat flow of the heat exchanger flows through fluid. The heat exchanger is inserted into a container (02). A complementary guide (21) includes a ring shaped guide rail and a counter guide. The guide rail is attached to the container, and the counter guide is attached to the heat exchanger. A wall (12) contributes reinforcement of the container and fixedly connected with the container.
