District heating is the use of heat from a central heat generator via a heating network to many connected buildings. It is an ecologically sensible and cost-effective alternative to individual heating systems and is easiest to use for buildings close to the heat generator. Waste heat, for example from data centers or other production facilities with high waste heat output, is now used to feed the heating network.

A major advantage is the higher efficiency compared to individual heating systems in the buildings. In addition, district heating offers the possibility of integrating renewable energies simply and effectively into the heat supply. In the beverage industry, district heating is an important way of saving energy and reducing theCO2 footprint. It is often used in breweries to heat water, clean tanks and dry raw materials. In addition to the use of solar heat, biomass or geothermal energy, waste heat from other processes can also be used, thus making a meaningful contribution to climate protection.

Frequency inverters can increase the efficiency of pumps used in the network within district heating systems. They make it possible to adapt the output of the heating systems to actual requirements and thus save energy.
