Heat pumps are known as zero-emission heating and cooling devices at the point of energy production. In order to exploit their advantages, they are combined with low-temperature heating systems. Using the example of a residential building in five climatic zones in Poland and one in Ukraine, systems analyses were carried out, in which heat into rooms is supplied in two different ways: low-temperature radiators and thermally active ceilings. The energy demand for heating, cooling and domestic hot water preparation was calculated. The seasonal coefficient of performance of the ground source heat pump was estimated to compare the systems. The results of the analysis confirmed that the thermo-active ceiling (with a flow temperature of 35°C) ensures a lower final energy demand when it works throughout the year in the heating and natural cooling mode compared to the low-temperature radiators (with a flow temperature of 45°C) which facilitate only the heating mode in the heating season. Performance analysis demonstrated differences in final electric energy demand from 8% in the I climatic zone to 9% in the V climatic zone in Poland and 10% in Ukraine.
