For over a hundred years we have been working with an eye to the territory and the society we are in. The commitment to sustainable development, both in the environmental and social sphere, is an integral part of our corporate philosophy.
CO₂ emissions reduction of 40% thanks to technology
During the total refurbishment of the hotel's heating plant in winter of 2017-18, 3 large stratified heat storage tanks with a volume of 2'000 l each were installed. Instead of the two modular boilers, fresh water stations based on the principle of continuous flow have been implemented; these draw the heat from the heat storage tanks and thereby break the power peaks of the new gas condensing boilers.
The aim of the stratified heat storage tanks is to preheat the water from the waste-heat produced by the hotel’s refrigeration systems (air-conditioning, cold-rooms and freezer-rooms) and, if necessary, to support the heating.
Hygienic warm water in drinking water quality
Thanks to the newly installed fresh water stations based on the principle of continuous flow, the drinking water is heated only when it is required. Hot water storage is therefore not necessary and consequently any risk of Legionella is excluded.
