The increase in energy consumption in the world, with the decreasing resources of conventional energy, is increasingly leading to campaigns aimed at limiting the acquisition of energy from non-renewable sources to intensify the use of alternative energy sources. The paper presents the possibilities of obtaining heat energy using a heat pump for heating purposes, ventilation and hot water preparation. Hot heat sources for the heat pump are discussed and their energy possibilities in relation to the geographical conditions of the territory of Poland. Variants of heat pump cooperation with renewable sources in the form of air, soil and water were adopted for analysis. Two cases of co-operation of the ground collector with the heat pump are also considered, in the form of vertical and horizontal wells of the heat exchanger type. Based on the known methodology of seasonal heat demand, the final and primary energy consumption was determined for each analyzed case together with auxiliary energy. Based on the calculations carried out, the final emission of carbon dioxide was determined for individual cases and they were compared with the emission that would be generated when producing heat using a gas boiler and heating network.
