ABSTRACT
Water heating in Pakistan and its neighboring countries predominantly relies on inefficient, natural gas-wasting water heaters whose mechanical design has remained largely unmodified since their inception in the 1960s. The inefficiency of these water heaters has added much to the woes of depleting gas reserves of the region, leading to a widening demand-supply gap. Pakistan is facing its worst ever natural gas crisis due to a COVID-19 hit economy that cannot carry the burden of expensive imports, especially during the Russo-Ukrainian conflict that has sent the gas prices soaring in the international market. We respond to this challenge with a sense of urgency by proposing a solution that minimizes the wastage of natural gas in water heating, which consumes about half the gas supplied to residential consumers in the country. Our solution replaces the mechanical control of the water heater with an IoT-inspired, electrical retrofit design combining hardware and software for smart control through user-defined schedules or machine learning, while solving several challenges that arise from replacing a mechanical control system with an electrical one. Empirical results demonstrate 70% reduction in consumption. © 2022 ACM.
