Original Abstract

The aim of this paper is to show the necessity of regulations for installations inside buildings by use of the simulation methods. Achievements of simulations operating conditions offer insight into the flow of water and heat transfer in a standing container to assess temperature and water stagnation. Due to stagnation of very slow water flow and also low overheating of thermal disinfection the point of highest risk is clearly bottom of the tank - so called sludge blow off. Here maintain suitable conditions for growth of Legionella bacteria, and if temperatures drop in the tank, may colonize the entire system.
