Intelligent and demand-driven district heating

Europe has the ambition to utilise district heating as the backbone of the energy transition because it holds the opportunity to store energy from unstable renewable energy sources, which can then be used to cover a rising heating demand and provide a vital contribution to the European ambition of reducing carbon emissions by 40% by 2030.

Europe has the ambition to utilise district heating as the backbone of the energy transition because it holds the opportunity to store energy from unstable renewable energy sources, which can then be used to cover a rising heating demand and provide a vital contribution to the European ambition of reducing carbon emissions by 40% by 2030. To realise these ambitions and utilise more renewable energy sources, Grundfos iGRID is creating low temperature zones in existing heat grids and effectively reducing heat losses and carbon emissions, based on the real-time demand. Grundfos iGRID is now being rolled out in the first European countries.

A success story: Heat loss reduction of >25% in the Greater Copenhagen area

A Grundfos iGRID setup in the Copenhagen suburb Gentofte shows a reduction in heat loss of almost 19% in year 1 and an expectation of more than 26% in year 2. This leads to a return on investment of the full project in less than 3 years.

In an area with approx. 300 large villas this leads to an annual heat loss reduction of more than 680 MWh that corresponds to a CO2 reduction of 165 tonnes, if it is based on the average 2017 EU CO2 index (GaBi).
