1 x 500 Liter HC buffer
650 m2 floor space
9060,56 kWh Total (20% WW + 80% HKR)
Total boreholes: 28 boreholes; total length of tubes 3.920 m
Max. flow - energy source side 25.800 L/h
Max. flow - heating side 15.500 L/h
The heating system is divided into three cascades á max. of 90 kW and therefore particularly sensitive to interference; inasmuch as the performance automatically adapts to the heating demands. These modulate between 35 and 270 kW, not only does the system’s efficiency increase but also makes it long-lasting. The low temperature heating system can heat up to 40 °C and cool down to 10 °C. This ensures an optimum room climate throughout the year.
- Annual heating costs with DHW: 9,270 kWh of electricity consumption
- Calori meter, total heating and DHW: 39,220 kWh = JAZ 4,23
A 850 L buffer tank and a decentralized fresh water system with a 2,000 L buffer storage is used for water heating.
Annual costs for heating and domestic hot water: € 3.480,- (29.000 kWh electricity for heat pump)
- Prevents approx. 300,100 kg of CO2 emmissions from heating oil
- Prevents approx. 97,000 mg of fine dust emissions per year from heating oil
Water used from Wilder Kaiser mountain range
Much energy is found in groundwater. Hourly, approximately 57,000 liters of water surface (1.3 million liters / day), which carry geothermal energy and stored solar energy. The energy is withdrawn from the water by a Heliotherm heat pump system where the water cools down and is released again into the circuit. The mountain water’s clean environmental energy is fed directly into the new wellness area, the brine pool and the sports pool.
Up to 500 kWh are generated every hour, can be generated void of local emissions.
In general, this technology concept was matched to meet the hotel upgrade design.
All installed components have been designed as a low-temperature heating system in order to cover as much of the energy requirement as possible through this environmentally-friendly heat pump technology.
Heating before: wood furnace
Heating room: 2 mixing circuits, 1,000 l buffer storage for PV-WP heat storage, 300 l hot water storage, solar module for shift to water storage buffer.
