Abstract: Electric heating has become in recent years the first choice for both industrial and household applications, since reduction of carbon dioxide emissions represents a major concern, and has caused replacement of solutions based on burning of gas or oil. Considering the importance of low energy consumption and increased functional safety, significant efforts have been made for design optimization. Microstructural analysis has determined that most of failures reported during exploitation and maintenance of electric heaters for production of hot water are caused by overheating of metallic components, although existing components are usually fabricated from heat resistant steels or super-alloys such as INCOLOY 800. Therefore constructive optimization has been based of an analysis of temperature distribution in heated water and on surface of heating element, using the finite elements, for both classical solutions, which are mostly based on empirical experience, and some !
new technical solutions that have been proposed to improve the existing design experience. The newly optimized solutions are based on new forms of heating elements, as well as different positions for water inlet or outlet. Simulations of temperature distributions indicate that optimized shapes of heating element are likely to improve both heating efficiency and reduce occurrence of failures.
