The Technical-Economic Analysis of Hot Water Supply Systems for Residential Buildings

Abstract

The article presents the measurements of hot water and supplied thermal energy consumption in residential buildings, where alterations in bottom distribution were made. Diagrams of hot water and supplied thermal energy consumption for 1 m³ hot water preparation were constructed, using the aggregated data. The research results show that hot water consumption differs from values offered in Regulations of Building Standard LBN 221-98, but the supplied thermal energy consumption for 1 m³ hot water preparation has considerably decreased.
