What Do Homeowners Want to Know About Storage Water Heater?

For families that need hot water at multiple outlets or for consecutive showers, a storage water heater is the clear winner. It preheats and stores 10–25 litres in an insulated tank, ensuring zero waiting time between users. An instant geyser is more suited for single-point, low-volume tasks like kitchen sinks.

• How Many Litres of Storage Water Heater Does a Family of Four Need?
