This paper provides a tabular analysis of an “outdoor air-water” heat pump in heating and domestic hot water system inside a multi-occupancy dwelling house. The study set out to compare a conventional system using the city’s district heat supply with one using an “outdoor air-water” heat pump. One part of the analysis is the energy performance of the renewable energy source. The study is also addressed the benefits of saving on conventional heat source and the period of financial return on the heat pump investment.
