Heat pump heating systems and low potential heat sources
This paper focuses on the application of renewable energy resources in the form of heat pumps and their use in heating systems. As the energy prices are constantly rising, the energy management is currently a very important issue. One of the main reasons is that obtaining the primary energy sources like coal and oil is much more difficult than in the past. The use of renewable energy sources has become a worldwide trend and is one of the ways to get cheaper and more accessible primary energy that has a minimum impact on the environment compared to conventional sources of energy (e.g.
