Dear members, I am working on a project and I need a circuit and working principles for the thermal controller that helps the shower heating system

Is this a school project?

If it isn't, then you can't get any cheaper/easier than these. By "shower heating system" I assume you meant a water heater?

I think he's talking about a control loop to keep the output temperature at a constant setpoint. Read up on PID (proportional/integral/derivative) control loops here. Look at the first sentence under "Control Loop Basics". Strange coincidence.
