  • For outputs up to 200 kW, approval of the air preservation authorities is not necessary.
  • For heat volumes up to 700 GJ/year, an opinion from the State Energy Inspection is not necessary.
Preconditions:
  • It is necessary to issue or update the Energy Performance Certificate for the building.
