Gas Condensing Boiler and Heat Pump Heating Systems Comparison

Zadatak ovog završnog rada predstavlja usporedbu različitih generatora topline u radu s više vrsta ogrjevnih tijela. Primarni cilj bio je pronaći idealno termotehničko rješenje za stan u Zagrebu koje najviše zadovoljava segmente potrošnje primarne energije, emisije ugljikovog dioksida te predstavlja relativno povoljan ukupni trošak energenta i investiciju. Detaljnom analizom predmetne zgrade i stana izračunati su toplinski gubici i potreba za potrošnom toplom vodom. Prema njima odabrani su elementi sustava grijanja. Služeći se softverom KI Expert te dobivenim informacijama oko troška investicije za svaki sustav zasebno došlo se do rezultata koji predstavlja radijatore s plinskim kondenzacijskim kotlom idealan izbor s ekonomskog stajališta. Iako dizalica topline predstavlja bolju opciju zbog manjih mjesečnih troškova i emisije ugljikovog dioksida, nažalost, početna investicija je još uvijek prevelika.This bachelor thesis deals with comparison of different heat generators working with several types of heating bodies. The primary goal was to find an ideal termotechnical solution for an apartment in Zagreb that satisfies the segments of primary energy consumption, low carbon dioxide emission and represents a relatively favorable total cost of energy and investment. With detailed analysis of the building and apartment, heat losses and the need for hot water had been calculated. According to them, elements of heating systems were selected. Using the KI Expert software and the information about the investment costs for each system, the result that represents radiators and gas condensing boiler an ideal choice from the economic standpoint was presented. Although the heat pump is a better option due to lower monthly costs and carbon dioxide emissions, unfortunately, the initial investment still remains too big
