First high-temperature heat pump in Berlin-Mitte starts supply revolution!

in the heart of Berlin, the new high-temperature heat pump at Potsdamer Platz is taking an important step towards sustainable energy generation. The Siemens Energy facility was officially put into operation on Thursday and will supply around 30,000 households with warm water and 3,000 households in winter with heating heat in the future. Christian Feuherd, Managing Director of Berlin Energy and Warmth (Bew), emphasized that the new technology not only serves to supply district heating, but also has a significant environmental impact by saving 6,500 tons of CO2 annually. The facility was funded by the federal government with 3.6 million euros and is an important project in Berlin's energy supply, which has been supplied with refrigeration since 1997 and numerous cultural institutions ( rbb24 ).

The functionality of the heat pump is very interesting: it uses the waste heat from the cold center to heat it up to 120 degrees Celsius and to feed it into the existing district heating network. According to Berliner Kurier are promoted as an environmentally friendly alternative to traditional heating systems, however, careful planning is crucial to avoid high costs. It should be noted that heat pumps only work effectively if the buildings are well insulated and the systems are dimensioned appropriately. A poorly planned installation can not only reduce energy efficiency, but also cause high operating and energy costs.

important aspects of installation

When planning a heat pump, the heating load calculation is essential. The flow temperature of the heating system should also be taken into account here. Values ​​between 35 and 40 degrees are ideal, while excessive flow temperatures in unanimized buildings can lead to inefficient companies. Two thirds of the energy that a heat pump needs removes the environment, which is why the correct choice of heat pump technology is decisive. Construction measures such as the insulation and the exchange of radiators can also be important to further maximize the efficiency and reduce long-term costs ().
