Indirect Heating and Charging DHW​

Vxe SLS villa substations, designed for Indirect Heating and Charging domestic hot water applications

A substation for indirect heating and domestic hot water preparation on charging principle is used when district heating network conditions, such as pressure and temperature, do not allow direct connection. When a substation is connected indirectly, a heat exchanger provides energy-efficient heat transfer. It also ensures that the primary network supply side and the secondary building installation side remain safely separated. 

In this way, the building application works regardless of pressure or temperature variations in the district heating network (hydronic balancing) and is safe from pipe breaks or leaks.

A high-efficiency heat exchanger is used for charging the hot water tank.
