ENERGY AND HOME COMFORT.

In this paper we aim to make a comparison between three types of heat pumps: air-to-water, water-to-water, ground-to-water. We show that, from a construction point of view, the difference between the three types of heat pumps is the source from which the additional heat is extracted. We point out that the heat pump is the installation that transfers heat from a colder medium to a warmer medium. Most often, pumps extract heat from water, air or ground/geothermal sources and transfer it into the home via underfloor heating, radiators, etc. Any decision to install heat pump equipment must be carefully considered, taking into account all four elements (energy consumption, installation costs, existence of the chosen heat source and its accessibility) that influence the technical and economic efficiency and the proper functioning of the equipment.
