Energy performance of domestic hot water systems
In this study there is performed assessment of the consumption of the heat energy in the apartment buildings for heating and hot water system, including: 1) assessment of the DHW volume and necessary energy amount; 2) assessment of the heat losses in the hot water distribution system during heating and non-heating seasons; 3) assessment of the auxiliary energy of the DHW system. The results of this paper give possible evaluation of economic feasibility and energy impact for improvements of domestic hot water systems. The method corresponding to CEN standards suitable for Latvian conditions is proposed.
