The article analyzes the annual operating costs for several hot water preparation systems and their impact on the environment; also estimating the emission of pollutants, mainly carbon dioxide CO2, which enters the atmosphere as a result of the use of heating installations. The article also investigated the impact of installing a DWHR heat exchanger on a sewage system, draining graywater from the shower on the annual operating costs incurred by users of hot water supply installations. For each heat source an alternative variant was adopted, in which the installation was additionally equipped with a heat exchanger. The amount of annual savings resulting from the installation of a vertical DWHR heat exchanger was determined, depending on the heat source for the hot water preparation system and the duration of the shower bath per one inhabitant. For the same dependencies, the level of reduction of carbon dioxide emissions into the atmosphere was also determined, as a positive effect of using the installation with a heat exchanger.
