Abstract

Aim: To suggest a design for a self-heating water bottle that can heat water when needed without the use of external power.
Method: The system first considered a Peltier-based heating strategy, which was later enhanced with a nichrome wire-based system for increased efficiency. A microcontroller-based temperature monitoring system and automatic cut-off mechanism were suggested, along with a small battery setup utilizing a 3D-printed triangular holder.
Results: Although Peltier modules showcased successful heating and cooling capabilities (in 60 min,1 L of water was cooled from 40◦C to 16◦C and another litre was heated from 25◦C to 45◦C) (Mazhar, Ubaid, Shah, Masood, & Alvi, 2023), a variety of studies have shown that nichrome is efficient because it is flexible, making it easy to fabricate the required component design, and because of its lower power consumption in comparison to the Peltier module. (Lim, Han, Thang, Lee, & Shin, 2024). This study was developed as a foundation for future design ideologies to pitch their innovation, experiment, and bring to the market a product capable of the aforesaid features.
