An environmentally friendly heating system has been installed on the roof of the health center in Dielsdorf. This should result in savings of 29 tons of CO2 per year. The system was installed by the Liechtenstein firm Hoval.

The Dielsdorf Health Center has turned to a sustainable technical heating solution. The Liechtenstein-based company Hoval recently installed a heating system the size of a small single-family house on the roof of the center, further details of which can be found in a press release. A solar energy system covers the rest of the roof area.

“The large area was well suited for the use of solar energy. The entire system was lifted onto the roof using a crane”, explains Edgar Stutz, Head of Technical Service at the Dielsdorf Health Center, in the press release. According to Heinz Hitz, Technical Sales Consultant at Hoval, only around 30 systems of this size are put into operation in Switzerland each year.

A gas condensing boiler and the solar panels form the core of the energy supply, with two energy storage systems located in the basement as well. When the energy storage systems have both reached the required temperature, the excess energy from the solar system is automatically fed into an older part of the building. In addition, the system is supplemented by an oil condensing boiler, although this is used exclusively in event of a breakdown.

In comparison with conventional heating systems, the Dielsdorf Health Center will be in a position to save 120,000 kilowatt hours of energy with its new system, according to Björn Zittra, Head of Sales Support at Hoval. “That corresponds to around 12,000 cubic meters of natural gas – or around 29 tons of CO2 per year”, he explains.
