Global Residential Water Heater Market Growth, Share, Size, Trends and Forecast (2025 - 2031)

Residential water heaters are categorized into two main types: instant (tankless) and storage (tank-based) models. Instant water heaters, also known as tankless water heaters, heat water on demand as it passes through the unit, eliminating the need for a storage tank. These units are prized for their energy efficiency and space-saving benefits, making them particularly suitable for smaller households or locations where space is limited. In contrast, storage water heaters store a reservoir of hot water in a tank, which is continuously heated to maintain a set temperature. This type of water heater ensures a ready supply of hot water but may consume more energy compared to tankless models.

Capacity segmentation is crucial as it addresses varying household needs based on water usage and family size. Water heaters are classified into different capacity ranges: less than 30 litres, 30-100 litres, 100-250 litres, 250-400 litres, and greater than 400 litres. Smaller capacity water heaters are ideal for single-person households or as point-of-use solutions in kitchens or bathrooms where hot water demand is minimal. Medium-capacity heaters cater to small to medium-sized families, providing adequate hot water for daily needs. Larger capacity heaters are suitable for larger households or commercial applications requiring a substantial supply of hot water.

The choice of fuel for residential water heaters predominantly includes natural gas and liquefied petroleum gas (LPG). Natural gas water heaters utilize a gas burner to heat water stored in the tank or flowing through the unit, offering efficient heating performance and cost-effectiveness in regions with access to natural gas infrastructure. LPG water heaters operate similarly but use liquefied petroleum gas stored in tanks for heating water, providing flexibility in locations where natural gas lines are not available. Both natural gas and LPG water heaters are favored for their rapid heating capabilities and continuous hot water supply, catering to varying consumer preferences based on fuel availability and cost considerations.
