The uncertainty regarding future subsidies for eco-friendly heating systems in Germany has apparently boosted demand significantly: According to Table.Briefings information, the KfW approved an average of 9,100 applications per week between the end of November and the beginning of December. This is an increase of 55 percent compared to the figures from the previous three weeks. Part of this increase can be attributed to applications for previously installed heating systems that could be submitted until November 30.
