Estimation of the economic addressable market of micro-CHP and heat pumps based on the status of the residential building sector in Germany

The analysis shows that the new construction of single family houses has the highest addressable market for heat pumps. The improvement of existing heating systems by heat pumps is only cost efficient, if an existing oil-based heating system is replaced. The use of micro-CHP units has the highest potential in multifamily houses. This applies for existing buildings as well as for the case of new construction. Nevertheless, the results just can indicate a tendency, how the market will develop in future.
