Due to the current interest rate reduction of the Reconstruction Loan Corporation (KfW) for solar credits to rates starting at 1.4 percent as well as rising heating costs, the costs for heating modernisation in connection with the installation of a solar heating system are currently being amortized even faster.

With simultaneous heating restructuring and installation of a solar system, heating costs can be reduced as a general rule by 30-50%, according to the Solar Economy Business Union e.V. (UVS) (German). This would save 1,000 liters of oil per year.

UVS and RLC provide free information about solar heating restructuring and means of promotion through the online guidebook www.solarfoerderung.de (German). (12.01.2005)
