Sistemas alternativos de aquecimento solar para água do banho no Estado do Rio Grande do Sul

Abstract

Buildings are responsible for almost half of the electricity consumption in Brazil, wherein the residential sector is responsible for the most energy consumption, amounting to 23.3% of total consumption. Due to the importance of reducing energy consumption today, this research will address the theme for solar heating waterbath, emphasizing alternative systems that do not require large financial investment, and that aim to reduce consumption of electricity and seek the financial economy. Since the higher power consumption of a residence is related to the electric shower and that the use of electricity should be reduced, it justifies the importance of using a system to heat the water different of electricity and reach the same goal: to heat water for bathing. The methodology used is a bibliographic research on systems for heating water, focusing on alternative systems, and then, making a comparison between conventional systems and alternative systems verifying their feasibility. Through this work, it was possible to conclude that it is feasible to use alternative systems, regarding the materials used, the initial cost and maintenance. These systems are good alternative heating solutions to streamline electricity, and are able to meet the needs of users (heating water for bathing) and without requiring big financial investments.
