Unlike instant water heaters, which heat water on demand, storage water heaters maintain a reserve of hot water, making it readily available for multiple uses, such as showers, laundry, and dishwashing. These heaters come in various tank sizes, typically ranging from 10 to 100 liters or more, depending on household requirements. They use electricity or gas to heat the water, and the insulation helps minimize heat loss. Storage water heaters are ideal for homes with higher hot water demands.
