The home in Haarlem, Holland was equipped with an 18 kW modulating Comfort Compact air heat pump, and an 800 L Heliotherm fresh hot water system, which supplies continuous hot water for 5 people.
Semi-detached residence with 2 x 125 m2 living space, heated with an air source Heliotherm Comfort Compact Series heat pump per residential unit.
The Heliotherm fresh hot water system ensures continuous hygienic hot water supply with minimal operating costs.
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).
System details:
2 x HP25L-M-WEB
2 x 850 Liter Fresh hot water system - buffer
1 x 500 Liter HC buffer
650 m2 floor space
9060,56 kWh Total (20% WW + 80% HKR)
The DHW is heated with a 2.000 L High-Level system.
Total heating output 270 kW modulating > 3 x 90 kW cascade system- Total cooling capacity 210 kW modulating > 3 x 70 kW cascade system
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 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.
This is a 5 person residence, the ACOP is 6.3. This home saves 4.300 kg of CO2 per year and has an heat output is 18.091 kWh.
before renovation:
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.
A well was drilled with a depth of 14 m. A fresh hot water system with 510 L was applied for the hot water system.
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.
