Streszczenie
The paper compares heat pumps driven by electric motors (EHP) with heat pumps driven by gas engines
(GEHP). GEHPs are still a novelty on the Polish HVACR market - therefore, the subject of the study is to indicate whether
in Polish climatic conditions their use is profitable. A thorough analysis of the energy consumption of selected devices was
carried out due to the consumption of utilities needed for their propulsion and the related costs. This has been done by
calculating seasonal efficiency coefficients and using an innovative method of comparative modifiers allowing for
unification of the performance of EHP and GEHP pumps. The results obtained include average energy efficiency
coefficients, operating costs and payback times. Discussion of the calculation results proved that under certain assumptions
GEHP pumps may be competitive with EHP heat pumps due to the possibility of managing waste heat at high temperatures.
