New ways of combining Heat Pumps and District Heating
In the Swedish research project Heat Pumps in District Heating Systems new combinations of heat pumps and district heating systems have been investigated. The project group has looked into three different way to combine heat pumps and district heating. Firstly, focusing on the combination of heat pumps and district heating in the manufacturing industry, secondly, hybrid heat pumps with the possibility to alternate between a heat pump and district heating depending on the energy prices, and thirdly, the combination of low temperature district heating and heat pumps for production of domestic hot water.
