Heating system for industrial applications

The paper presents a theoretical approach about a heating system for industrial applications which could be transffered to a domestic application regard of how to automatically heating the water, from a input value until an heigh output value. Heated water could be used in different industrial technological processes, also at domestic houses or office buildings to prepare hot water. In this paper it's descriebed an automatic heating system — tankless, which has the advantage to use a small dimensions and could be mount in narrow spaces. The main purpose is to maintain a higher temperature of the heated water depending on the industrial or domestic application. Coupling or decoupling at different intermediate heating steps using power resistors is achieved with static contactors which are built with thyristor in antiparallel or triacs mounted on their grids depend on output temperature. Temperatures could be measured in steady-state or transient regime. One of the goal is to obtain a higher increasing of temperature in shortly time.
