The tankless water heater market figures in this report are based on a proven research process that combines executive interviews with secondary research from proprietary databases, company filings, and recognized regulatory and institutional sources. Market size is built through value-chain sizing - reconciling supply-side and demand-side estimates - and triangulated with bottom-up and top-down approaches. Every estimate passes multiple levels of expert validation before publication, with each tankless water heater segment quantified using the revenue-capture definitions in the table below.
Segment Definition
Segment - Type
Revenue capture definition
Electric
This segment covers the revenues generated through the sales of electric tankless water heaters that heat water instantly using high-powered electrical heating elements without the need for storage tanks. These systems are widely used in residential apartments, small homes, and point-of-use applications where space efficiency and easy installation are key requirements. Electric tankless systems eliminate standby heat loss and provide on-demand hot water with improved energy efficiency. Real-life examples include point-of-use bathroom heaters, under-sink instant water heaters, and whole-house electric systems used in compact urban apartments, smart homes, and energy-efficient housing projects.
Gas
This segment covers the revenues generated through the sales of gas tankless water heaters that heat water instantly using natural gas or propane burners instead of electricity, providing high-capacity hot water supply on demand. These systems are commonly used in large residential households, commercial buildings, hotels, and hospitality facilities where higher hot water flow rates are required. Gas tankless water heaters are known for their ability to deliver continuous hot water supply for multiple outlets simultaneously while maintaining lower operating costs in gas-available regions. Real-life examples include wall-mounted condensing gas water heaters, whole-home systems installed in villas and hotels, and commercial-grade units used in restaurants, laundries, and healthcare facilities.
