A heat pump uses natural energy from renewable sources such as air, ground or water. The pump, acquiring thermal energy from the environment (75%) and using electricity (25%), supplies it to the heated object. A heat pump-based system consists of a ground heat source (heat is taken from it), a heat pump unit and an upper heat source (heat is transferred to it). The refrigerant transfers heat from the lower heat source to the upper heat source. The paper discusses types of heat pumps in terms of the use of the lower heat source. A technical and economic analysis was carried out on the basis of two types of heat pump: air-to-water and ground-to-water A comparative analysis of the results obtained results will allow a real assessment of the system’s functioning.
