What is an Electric Water Heater? - Rheem

Electric storage water heaters heat and retain a quantity of water in an insulated cylinder, ready for use. They provide hot water at mains pressure, and as they can deliver the whole stored quantity immediately it’s needed, can service many outlets at the one time. And it will deliver to them all at mains pressure. When emptied, it takes time to reheat to have you back in hot water, but they heat water quickly, especially with more powerful or twin elements, and can be run on lower cost off-peak electricity. Rheem’s range also includes adjustable temperature thermostats and 7 year and 10 year cylinder warranty options. They can be installed indoors or outdoors, and are available in small through to large capacities including small units that fit under a kitchen bench and heat a lot of hot water in a short time – ideal for apartments.
Installation is restricted in some areas and applications– ask your plumber what restrictions apply in your area.
