The paper presents operation examination results of a heating system equipped with a heat pump, manufactured by the Sekut company, equipped with a scroll type compressor. The performed statistical analysis has shown a significant influence of external temperature and heat transfer coefficient to the COP value. Within the analysed period, the COP maintained a level of 2.6 at an average monthly temperature of -6°C, with a transfer coefficient of 15%.

"The analysis of the energy demand for heating and cooling of the house built on the basis of the modernised Canadian wood-frame construction". This study shows calculation of demand for power needed for heating and cooling of a house built in compliance with modernised Canadian wood-frame construction technology and by modern solutions of construction details connections. Conducted calculations prove that the passive house built of wood-based materials enables to achieve the highest efficiency of thermal power demand for heating the building.
