Summary:

The paper presents an analysis of energy absorption and the costs of the energy for heating single family houses situated in the city of Jasło. The conducted research demonstrated a considerable diversification of material and construction solutions of the walls and the applied heating systems. Values of the heat transfer coefficient for exterior walls exceed the currently applied standards in most buildings. Heating systems are mostly hard coal fired. Warm water preparation supported by solar thermal collectors was used only in several houses. Analysis of the research results revealed a lack of correlation between the energy costs and heat transfer coefficient for the external walls.
