About us

Crafting Comfort with Expertise.

We are a Taiwanese team that has spent 25 years perfecting the art of crafting storage water heaters. We don't just see showering as a daily routine but a special moment to relax and rejuvenate. 



Our passion for innovation has led us to develop heating technology recognised by global patents from the US, Germany, the UK, China, and beyond.

With our dedicated R&D team and manufacturing facility, we oversee every step, from innovation and component selection to quality assurance and optimisation. Our goal is to provide every family with a water experience that not only meets their needs but also brings a touch of care to everyday life.

Caring for Your Well-being Today, Innovating for Tomorrow.

John, the founder of Esio, was driven to transform the narrative around water heaters after witnessing his father's scalding injury during his childhood. His observation of the market's safety and quality imbalances, especially during his construction career, prompted him to conduct in-depth market research. 



He discovered that many storage water heater brands are lacking innovation and essential features. Key components like the heating element, thermostat, insulation foam, and inner tank material were often neglected, leading to premature aging and frequent breakages.

Motivated by this, John founded Esio, a brand emphasising the importance of every aspect of a water heater. Despite lucrative opportunities for original equipment manufacturing from reputable global brands, John insisted on operating Esio independently. 


This decision allowed the brand to meticulously oversee every detail of product manufacturing and quality assurance. Ensuring that every family receives a safer and professional hot water experience.
