Continuously and over the years we invest in sustainable energy and try to optimize our ecological footprint. In the past, we heated with oil and geothermal probes. An air-source heat pump has been added to the energy concept, which uses the outside air as a heat source. Two types of heat pumps are combined: A winter pump and a summer pump. Which regulate and adjust themselves according to the natural temperature changes of the seasons. Furthermore, with our own photovoltaic system on the roofs and balconies, electricity is produced and fed into the grid. We achieve 300,000 kWh annually. Through these measures we have reduced the heating oil consumption by 65 percent, which means we save 70'000 liters of heating oil per year. We support our guests who arrive with electric vehicles. You can conveniently charge your cars in our own parking garage at our electric charging stations.
