摘要

The German space heating sector is responsible for about 19% of Germanys CO_2 emissions and so the second largest emission source (behind electricity production). Moreover, the sector is still regarded as an area with high potential for reducing GHG at low – or even negative – costs. Politics is now trying to realize this potential by a law, which forces house owners to use 10-20% renewable energy such as solarthermal energy, wood or heat pumps for space heating. One federal state has already passed this law in November 2007 and the Federal Government is expected to pass such a law for the whole country in the current year. Moreover, high oil and gas prices also affect the heat market and favour the entry of alternative solutions. This paper tries to analyse the impacts of the new legislation and of rising prices for fossil fuels on the market for space heating until 2020. A focus is hereby set on heat pumps. The sales of those boomed in the last years reaching a market share of about 8% of the newly installed heatings in 2007 and are expected to grow further. Thus, it is very interesting to have a look on the future of heat pumps in Germany.
