Berlin, Germany

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 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 2,000 l solar storage tank: split storage into a smaller tank
  • Overheat in case of no heat demand: safety connection to outdoor fan coil unit from BoostHEAt circuit
