Comparison of investment and operating costs between different types of heat pumps (for the new low energy house and an old poorly insulated house

V diplomski nalogi so predstavljene prednosti in slabosti posameznega tipa toplotnih črpalk (zrak/voda, voda/voda in zemlja/voda) ter njihove prednosti in slabosti pred konvencionalnimi viri ogrevanja (zemeljski plin, kurilno olje, biomasa). Prikazan je izračun toplotnih izgub za novejšo nizkoenergijsko hišo in starejšo slabo izolirano hišo. Narejena je primerjava investicijskih in obratovalnih stroškov posameznega tipa toplotnih črpalk za oba objekta in ekonomska analiza odplačilne dobe investicije za 15 let. Investicijske in obratovalne stroške ter odplačilno dobo investicije posameznega tipa toplotnih črpalk smo primerjali s stroški za sisteme na konvencionalne vire ogrevanja (zemeljski plin, kurilno olje, biomasa).This diploma work presents the advantages and disadvantages of different types of heating pumps (air/water, water/water, earth/water) and their advantages and disadvantages compared with conventional heating systems (natural gas, heating oil, biomass). Diploma work also includes calculation of heat loss for the newer low energy house and older poorly insulated house, comparison of investment and operating costs of each type of heat pumps and economic analysis of investment for 15 years, for both objects. Investment, operating and repayment costs of each type of heat pumps were also compared with costs for conventional heating systems (natural gas, heating oil, biomass)
