Goal of the hotel (accommodation in the spa):
Reduce carbon footprint and generate electricity and heat for the hotel and on-site spa.


Pellet biomass cogeneration plants “E3” and “WE-50P” were installed. The heat from both biomass cogeneration plants (180 kW in total) is used in cascade for water heating, air conditioning, floor heating and street heating in the complex.

Services and benefits

  • The electricity generated is used within the hotel.
  • Part of the electricity is fed into the local community.
  • The generated heat is used within the building.
  • By using the heat from the CHP units, the operating time of the boilers has been significantly reduced.
