Tankless water heater market seen reaching $7.7 billion by 2033

By AI, Created 12:10 PM UTC, May 21, 2026, /AGP/ – The global tankless water heater market is projected to grow from $5.0 billion in 2026 to $7.7 billion by 2033, driven by energy-efficiency demand, rising electricity costs and adoption in homes and businesses. Asia Pacific leads the market with about a 46% share, while North America and Europe remain important growth regions.

Why it matters: - Tankless water heaters are gaining share because they cut standby energy losses and can lower utility bills. - The market is expanding alongside global pressure to use less energy in homes, hotels and commercial buildings. - Asia Pacific accounts for around 46% of the market, underscoring how adoption in Japan, China and South Korea is shaping global demand.

What happened: - Persistence Market Research values the global tankless water heater market at US$ 5.0 billion in 2026. - The firm projects the market will reach US$ 7.7 billion by 2033. - The forecast implies a compound annual growth rate of 6.3% from 2026 to 2033. - The report was published in London on May 21, 2026. - A free sample of the study is available here. - Report customization is available here. - The complete report is available for purchase here.

The details: - Tankless systems heat water on demand, which removes the continuous energy use common in storage water heaters. - Rising electricity costs are adding to demand for efficient heating systems. - Residential buildings remain the largest end-user segment. - Homeowners are replacing traditional storage heaters with tankless units to save space and improve efficiency. - Commercial demand is rising from hotels, hospitals and office buildings that need continuous hot water with lower operating costs. - Electric tankless water heaters are becoming more popular in homes because they are easier to install. - Gas-based systems remain common in high-demand commercial settings because they heat water faster. - Product development is centered on improved heat exchangers, smart temperature controls and Wi-Fi enabled monitoring. - Online and ecommerce channels are gaining traction as consumers look for convenient purchasing and installation services. - Report segmentation covers condensing and non-condensing technology, electric and gas energy sources, three efficiency bands, multiple sales channels and six regional markets.

Between the lines: - The market is being pulled by two forces at once: consumer interest in convenience and policy pressure to improve energy efficiency. - Smart controls and connected monitoring suggest tankless water heaters are moving from a basic appliance category toward a more digital home and building product. - High upfront installation costs and maintenance needs remain a drag on faster adoption. - Competition is likely to intensify as manufacturers compete on efficiency, durability and smart features rather than price alone. - The named companies active in the market include A O Smith, Ariston Thermo, Bradford White, Haier Smart Home, NORITZ, Rheem, Rinnai, Robert Bosch, Bajaj Electricals, Kyungdong Navien, Whirlpool, Stiebel Eltron, EcoSmart Green Energy Products, Hubbell Electric Heater, Vaillant Group and Paloma.

What’s next: - Market growth is expected to continue through 2033 as residential modernization and commercial construction broaden use cases. - Smart home integration should create new demand for advanced water-heating systems. - Emerging markets in East Asia, South Asia and Oceania, Latin America, and the Middle East and Africa offer room for further expansion. - Manufacturers are expected to keep using partnerships, mergers and product launches to expand reach and defend market share. - Continued investment in energy efficiency and lower-carbon systems will likely shape the next round of product development.
