ABSTRACT
The paper discusses hot water system and controlling of the restoration of residential buildings, discusses the possible causes and consequences of the improper operation and also discusses possible ways of resolving these problems. Currently, we meet with a comprehensive rehabilitation of the housing stock, as part of the thermal insulation of residential buildings, thermostatic regulation of heating systems and comprehensive exchange of piping system in the house. Until these modifications are introduced considerable sums of money from which residents of flats often expect miraculous savings and reduce the cost of housing. Are demonstrable savings for building insulation, thermostatic balancing central heating and replacement of piping system uptime guarantees and often improve the supply of hot water, cold water, safety of operation of gas distribution and improving hygiene after replacing sewer lines. The paper discusses the basic rules when replacing piping hot water, the most common causes of defects and the operation depending on the hot water system and balancing of hot water. Current water heating systems waste up to 20% of their energy due to poor insulation in pipes or water tanks, but improving this insulation is too costly to be practical for energy savings [1].
