The Global Storage Water Heater Market was valued at USD 22.2 billion in 2025 and is estimated to grow at a CAGR of 6.3% to reach USD 40.6 billion by 2035.
Growth is driven by technological advancements, including superior insulation materials, smarter control systems, and more efficient heat exchanger designs that enhance the performance and usability of large-capacity units. Rising adoption is further supported by stricter domestic and international energy efficiency standards, as well as increasing investments in sustainable water heating solutions. Businesses are prioritizing energy-efficient, environmentally friendly water heaters to meet corporate sustainability targets, while government incentives, rebates, and tax credits are motivating commercial and residential upgrades. Integration with smart grids and renewable energy sources, such as solar thermal and geothermal systems, enables optimized energy use, lower costs, and reduced reliance on fossil fuels. Urbanization, rising living standards, and electrification in emerging markets further bolster adoption, positioning storage water heaters as essential in both residential and commercial applications.
The residential segment is expected to grow at a CAGR of 5.5% by 2035, driven by increased household energy demand and a need for reliable hot water for daily use. Energy-efficient models, equipped with enhanced insulation, smart thermostats, and home energy system integration, are reducing utility costs while improving convenience and performance.
The 30-liter category is projected to reach USD 4 billion by 2035, favored in smaller households, apartments, and space-constrained areas. These units are ideal for point-of-use applications, including kitchens and bathrooms, where quick heating and limited hot water requirements are common. Growth is supported by rising urbanization, compact housing trends, affordability, and expanding electrification in emerging economies.
U.S. Storage Water Heater Market reached USD 3 billion in 2025, with growth fueled by energy storage integration and strong investments in renewable energy projects. Solar-plus-storage adoption is increasing, driven by the demand for reliable, sustainable hot water solutions.
