Optimal Disturbance Control for Energy Feedback of Gas Water Heaters

In order to improve the recovery and utilization of hot water energy in gas water heater pipes, a self-powered solution is proposed in this study. The proposed solution focuses on improving energy collection efficiency by increasing the heat transfer coefficient of the water flow and tracking the maximum output power of the temperature plate. The design of heat transfer structure, power characteristics of temperature plate and circuit conversion are analyzed. In order to verify the feasibility of the proposed solution, a test device was constructed for physical testing and verification. The experimental results demonstrate the successful implementation of the self-powered gas water heater. The special structure and perturbation method used enable the experimental device to achieve the maximum power output, and the experimental device can continuously provide 300mW output power. This research contributes to the development of energy -efficient and self-powered gas water heater solutions, offering potential benefits for energy saving and sustainable use in the residential sector.
