IEA HPT Annex 47 Heat Pumps in District Heating and Cooling Systems

One objective will be to suggest how heat pumps can be implemented in both new and old district heating systems in the best way. The different types of integration will be described. The differences and possibilities in integration in both central and local systems will be described. The possibilities of increasing a larger share of renewable energy or using excess heat in the different systems by using Heat Pumps will be a focus area. Minimizing the system losses by using Heat Pumps will also be an objective.
Existing projects where heat pumps are integrated in district heating systems will be described and evaluated for each participating country. The market potential and economic opportunities will be evaluated and described for each participating country.
