Hotel Saratz

For The Sake Of The Environment And NatureClean Energy

The interior of planet earth holds enough energy to ensure the supply on its surface – and that in a clean and environmentally friendly fashion. Reason enough for Hotel Saratz to build its own geothermal energy production facility.

Brief explanation of the facility:

  • A borehole with a depth of 1500 m, the first in Switzerland, was sunk in the hotel garden for the production of renewable energy.
  • Water circulating at this depth is warmed to 43°C quite naturally by the heat of the earth.
  • This warm water is introduced into the circulation system by means of a heat pump. During this process, the available heat is extracted and then the water, now cooled to 8°C, is getting pumped back into the circulation system.
  • Hotel Saratz uses the energy gained to heat the hotel’s indoor pool and wellness zone as well as part of the hotel complex. Oil-fired heating is also available to cover times of peak load.
  • The result: by this means, Hotel Saratz saves about 125,000 litres of heating oil per year, equivalent to a CO2 emission of 370 tonnes per year. Around 90% of the heating requirement can be met by using geothermal energy.

Hotel Saratz is thus making a contribution to maintaining the quality of air and life in the Engadine for future generations. The valley has an affinity with, and a long tradition, in the energy sector: it is the “dry chamber” (322 annual days of sun) as well as one of the water-wealthiest valleys in the Alps.
