Zusammenfassung:
The article evaluates various types of heat source used for heating and ventilation in a typical singlefamily house. Additionally, the paper presents the ecological analysis of the proposed solutions according to The National Centre for Emissions Management (KOBiZE) standards. The analysis was carried out for commonly used heating systems such as a gas boiler with closed combustion chamber, an air-source heat pump (ASHP), a ground source heat pump (GSHP), a coal fired boiler and a wood fired boiler. Moreover, the paper describes the energy performance and energy balance of a typical single-family house. Ultimately, the ecological choice of heating system was presented.
