Long-time and effective control of water temperature is critical for both commercial and domestic use. This project designs a new dual-application water temperature control system for drinking and bathing water use by integrating thermoelectric cooling and immersion heating technology. The system employs a Peltier coil water flow block in cooling and an immersion water heater in heating. A fan-based heat dissipation scheme enhances thermal efficiency to ensure optimal system performance. An ESP-based microcontroller offers automated water level control and real-time monitoring through tank refilling control and monitoring of water levels. A temperature sensor DS18B20, with its precise thermal measurements within the storage tank, offers precise feedback control. The switching process of heating and cooling is maintained through a relay-based switching mechanism, ensuring that maximum energy efficiency is retained with optimal temperature levels. This system provides an innovative, energy-efficient, and affordable means of regulating the temperature of water in domestic and business premises. Monitoring enabled through IoT further increases user-friendliness by allowing real-time monitoring of temperatures and automated regulation of the system. The suggested method increases convenience for users and promotes eco-friendly use of resources by offering a flexible and scalable solution to existing issues of water heating and cooling.
