Replacing the gas boiler with new device

Zamjena plinskog standardnog bojlera novim ureĊajem opisana je teorijskom analizom zakona i pravilnika koji propisuju pravilan naĉin proraĉuna potrebne toplinske energije za grijanje obiteljske kuće, te su opisane plinske tehnologije i principi njihova rada. Provedeni su proraĉuni i usporedbe u raĉunalnom programu Thorium A+, trenutnog i budućeg stanja s ciljem na uvid u potrošnju toplinske energije kao i buduće uštede. Za primjer novog stanja uzet je u obzir plinski kondenzacijski bojler kao i ugradnja termoregulacijskih ventila na ogrjevna tijela. Dokazane su uštede u potrošnji primarne energije te isplativost investicije ugradnjom novih tehnologijaThe replacement of the standard water heater with a new one has been described by theoretical analysis of laws and regulations in which is described a correct way for calculations of thermal energy, needed for family house heating, and also gas technology and their working principles. Calculations and comparisons for the current and the future conditions have been conducted by Thorium A+ software, to get the insight of thermal energy consumption and savings in the future. As a new condition, a new gas condensing boiler was considered with installation of thermoregulatory valves on the radiators. Savings in primary energy consumption and costeffectiveness of the investment with the incorporation of new technologies have been prove
