Indirect Heating and Primary connections for charging DHW systems or cylinder

Villa stations and district heating stations covering all Indirect heating & primary connections for charging DHW systems or cylinder applications

An indirect substation with primary connections for charging DHW systems or cylinder applications 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.

Charging DHW systems or cylinder needs to be connected to the station for domestic hot water purposes.

Features and benefits

Integrated components ensure safe operation, increases durability and minimize whole life costs

Benefit from optimized heat transfer and system control performance

Compact design - Minimum space required for installation

Thermostatic or electronic control of heating and cylinder temperature 

Operates independently of differential pressure and flow temperature

Low energy loss

Wide capacity range – up to 115kW
