    Overview

    Introducing the Rinnai 400L 4.8kw Hotflo Electric Hard Water Single Element Storage System. This storage system is equipped with a twin element feature, ensuring efficient heating of water. The vitreous enamel lined steel cylinder stores water and is heated by two thermostatically controlled heating elements. One element is situated at the base of the cylinder, while the other is located near the top. The bottom heating element effectively heats the entire contents of the cylinder, while the top heating element, also known as the booster, operates during high demand periods to heat the upper portion of the cylinder's contents. With this system, you can enjoy a consistent supply of hot water, even during peak usage times. The Rinnai 400L 4.8kw Hotflo Electric Hard Water Single Element Storage System is designed to meet your hot water needs efficiently and reliably.
