Introduction
Hot water in Southeast Asia used to mean gas heaters or bulky storage tanks.
That picture is changing fast.
Compact, on-demand tankless electric water heaters are now transforming bathrooms across the region.

The Shift Toward Instant Hot Water
Urban homes in cities like Bangkok, Jakarta and Manila are getting smaller.
A wall-mounted tankless unit frees up valuable floor space by eliminating the storage tank.
Add rising middle-class demand for modern comfort, and the shift is clear.
Instant, endless hot water is quickly becoming the new normal.

Strong Growth Over the Last 3 Years
From 2023 to 2025, the Southeast Asian tankless electric water heater market grew at a CAGR of roughly 16–19%.
In 2022, urban household penetration was only around 18–22%.
By the end of 2025, that number surged to an estimated 33–38%.
Thailand, Vietnam and Indonesia are the main growth engines, driven by residential building and renovation booms.

Tankless Water Heater Coverage Across the Region
Coverage differs by country, but the trend points firmly upward.
In Thailand and Malaysia, tankless units now account for over 40% of new residential water heater installations.
In Vietnam and the Philippines, where uptake was slower historically, penetration has nearly doubled since 2022.
Even smaller cities and towns are seeing a rise, thanks to e-commerce platforms that make purchase and installation simple.

Drivers Behind the Surge
Several forces are pushing adoption higher.
New condominiums and apartments are installing tankless units as standard to save space and energy.
Expanding electricity access and improved wiring in rural and semi-urban areas are opening up new customer segments.
Hygiene habits adopted during the pandemic have led to more frequent warm-water bathing.
And governments are encouraging energy-efficient appliances, where tankless heaters have a clear advantage by heating water only when needed.

Looking Ahead
Forecasts suggest urban penetration in Southeast Asia could surpass 50% by 2027.
Smart-home integration and eco-conscious consumer habits will further accelerate growth.
