Berlin (Germany)
Demo responsible: BoostHEAT
Type of building: Small residential. House with 2 apartments (220 m2) in the town center of Berlin. Solar energy potential: 10 m2. Existing individual gas boiler per flat for supplying Domestic Hot Water (DHW), space heating through radiators. Yearly heat demand: 60MWh,th
Demonstration action:
- TP1, Parallel integration: Solar thermal (TVP) for space heating + DHW; HP boiler (BoostHEAT) to cover non solar periods.
HP boiler Adsorption chiller Reversible HP Solar thermal PV Thermal Energy Storage RES installed 20 kW — — 7.5 kW — 2,000 l 21.4 kW
- Solar panels installation on flat roof and connections to the cellar room
- BoostHEAT and thermal energy storage (RATIOTHERM) installation in the cellar
- Integrated control system for the smart operation of H&C
- Redesign centralized space heating and DHW distribution system for the 2 flats
- DHW and space heating meters per flat for operation costs breakdown
Replicability potential:
- Small residential (single houses) with natural gas connection. New and renovated buildings.
- All climates
Technical risks:
- Access to the cellar for integration of the 2,000 l solar storage tank: division of the storage tank into a smaller tank
- Overheating in the absence of heat demand: safety connection to the outdoor fan coil unit in the outdoor area from the BoostHEAt circuit
