Charging stations are used to load a hot water tank - either from an upstream buffer tank or directly from the heat generator. If the temperature drops below the set temperature, the charging cycle is started. If the temperature at the heat source is insufficient, a request is made to the heat generator via a potential-free contact. The charging Systems
of unitec Energietechnik GmbH offer the perfect solution especially for systems with high short-term peaks.

The built-in speed-controlled high-efficiency pumps ensure a low return temperature to the heat generator or buffer
tank. Depending on requirements, two stations can be switched in cascades. Thanks to the innovative structure of the stations, the plate heat exchanger cools down within seconds. This leads to a massive reduction of the calcification problem.

This system allows a large amount of hot water at the desired time, which can be used by the consumer. This simple switchover means that the heat generator can be made significantly smaller and does not have to be
able to fully cover the peak times - this saves money and protects the environment!
