Civic heating systems

Potable water compact stations
Primary compact stations
Gas compact stations

These stations are integrated for central potable water heating, which may also be completed in the necessary kilowatts.
The primary stations are switched intermediately between the primary grid and the building-side secondary grid and also matched individually to the necessary kilowatts.
The gas compact stations are used by industry for supplying plants.
