ABSTRACT

The aim of the article is based on an analysis of heat losses arisen before the renovation of hot water distribution pipeline of a selected residential building and after the subsequent renovation is to design possibilities for more efficient insulation. Three alternatives of insulation thickness in terms of heat loss along with the condition of the existing isolation after the renovation of the distribution pipelines and with the condition before the renovation are compared in the article.  By choosing a suitable insulation, energy efficiently operation will take place in the hot water supply which has a direct impact on operation economy, and finally it leads to reduction of environment pollution through fossil fuels saving.

Keywords: hot water, hot water distribution pipeline, heat loss, thermal insulation
