For this project, a house built in 1963 was rebuilt by replacing it in 2019 with a new building in a modern design.
The family home with a living area of 209 sqm is heated with a Heliotherm high-efficiency air to water heat pump from the Comfort Compact series.
Using the new heat pump saves heating costs and ensures environmentally friendly operation.
- The house now has a heating energy demand (without hot water) of 5705 kWh.
- To cover the annual heating energy demand, the heat pump requires an average of 1300 kWh of electricity.
- The annual heating costs can be calculated with the current electricity price (UK) of £ 0.06 / kWh. The costs (without hot water) are £ 78.
In cooperation with our Competence Partner installing company 5D Dalmacija, and the high-end modern hotel in Privlaka is equipped with a Heliotherm Air Solid Split large heat pump. The heat pump system brings high performance heating and cooling to the five apartments with a total of 850 m2 of living space and a swimming pool.
Hotel Mariasteinerhof is a 4-Star Hotel accomodation that makes a holiday dream come true!
The newly built luxury chalets are a "technological foresight" and peaceful living comfort where you can enjoy your holiday in the midst of the idyllic Kitzbühel Alps and enjoy your stay in harmony with nature. The chalets are equipped with state-of-the-art Heliotherm heat pump technology, creating an accentuated environmentally friendly and energy-efficient heating system.
The Heliotherm Basic Comfort Air Heat Pump - Split Design Modulating, heats a commercial building and a double multi-family property with full occupancy. The owners have achieved the goal of an environmentally conscious and climate-friendly heating system in their properties attained with a Heliotherm heat pump system. In addition to the renovation of the heating system, the properties renewed the thermal insulation and installed new windows.
Residential building with 2 apartments
Thermally renovated 2010 (full thermal insulation, roof insulation, windows replaced, built-in roller shutters)
Generated heat: 18,909kWh (14,617kW heating + 4,292kW hot water) in the first year of operation
Before the renovation project
- Annual heating costs: € 1,896.00
After renovation was completed
- Annual heating costs without domestic hot water: € 636,-
- Annual heating costs with domestic hot water: € 823,-
- Monitoring: RCG2 - SCOP 3.37
The Heliotherm fresh water system with storage and buffer storage takes care of that Daily hot water preparation for 4 people (2 adults and 2 children).

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 without DHW: 6,150 kWh of electricity consumption
- 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.
The family Gassenbauer of two, heat their home with the Basic Comfort Series a fully modulating air heat pump - split design. The outdoor evaporator is the innovative Silent Source air evaporator. The monitoring device that compliments the state-of the art heating system is the Gateway Remote Control GRC.
27 flat units with 1.800 m2, underfloor heating in wet-system.
A 2.000 L buffer storage was used for the DHW.
Annual costs for heating and domestic hot water: € 3.480,- (29.000 kWh electricity for heat pump)
- Replaces heating oil of approximately 115,000 liters / year
- 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.
The Comfort Compact air heat pump is equipped with a PV module. In addition, the Independence Package 2 (6 photovoltaic modules) was installed by Heliotherm.
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.
