Desenvolvimento de simulador online para análise financeira entre sistemas de aquecimento de água – Solar, chuveiro elétrico e aquecedor a gás. Orientadora: Micheline Damião Dias Moreira. 2022. 57 f. Trabalho de Conclusão de Curso (Graduação em Engenharia Civil) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2022.https://repositorio.ufrn.br/handle/123456789/50263Technological innovations, increasingly linked to residential comfort, cause the diversification of heating systems, which promotes energy efficiency in favor of sustainability and accessibility to the various models in larger proportions. In this context, the present work aims to create an online simulator that interacts with the user through an accessible language, questioning the possible variables that may interfere in the sizing of hot water systems, performing a financial comparison between the solar heating models with boiler, electric shower, and individual passage gas heater. Therefore, the user will be able to implement one of these systems rationally, considering that the platform will return an individual result according to the needs of the residence. Finally, it was concluded that, among the studied heating systems, the solar heater with boiler would be interesting for homes with many points of use and residents. At the same time, the electric shower would be cheaper among all the models. However, it significantly compromises the cost with electricity in the long term and does not provide as adequate comfort as the other options. The gas heater, in turn, did not have a satisfactory financial performance when analyzed for large families because of the high cost of implementation and operation over the years, being a good ally to the comfort aimed at small homes, guaranteeing the possibility of heating for the various points of use.Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Simulador de aquecimentoBoilerSolarChuveiro ElétricoGásHeating simulatorBoilerSolarElectric showerGasbachelorThesis
