A relatively inexpensive solution to your hot water needs, electric water heaters are ideal for use with money saving off-peak tariffs and are available in a range of sizes to suit most needs. Whether you're a small family on a budget or a larger family with a big demand for hot water, we have the solution that is right for you. We are Rheem preferred stockists and prefer to supply Rheem electric water heaters due Rheem's longevity in this market; they have been manufacturing water heaters in Australia since 1939.
An Electric Storage Water Heater consists of an insulated storage tank where hot water is kept ready to be used. The water is stored at a pre-set temperature, typically 60-80°C. The water is heated in the storage tank by one or more electric resistance elements, which are located at the bottom and top of the storage tank. Each element is controlled by an independent thermostat.
Electric water heaters operate in the same way as an electric kettle heats water, but, unlike the kettle, an electric water heater keeps the water hot. Over time, the water temperature decreases through heat losses from the storage tank and from hot water draw-offs (usage). This results in the tank being refilled with cold water which in turn lowers the overall temperature of water in the tank.
An electric water heater is usually relatively cheap to buy and install, but is usually the most expensive to run, especially if it's on the continuous (full day) rate. Systems that run on off-peak electricity are much cheaper to run, but need a larger tank as the water heated overnight has to last you all day. And off-peak electricity isn't available to all homes. A four-person household typically needs a 125-160L tank for a continuous system or 250-315L for off-peak.
The new benchmark in electric water heater performance and durability. Rheem Stellar® Electric combines high thermal efficiency with the purity and performance of a stainless steel cylinder in a range of popular model sizes ranging from 50lt-315lt.
Rheem 250L-400L electric water heaters are designed and manufactured by Rheem. This new and improved range of products designed to deliver maximum performance and reliability, backed by a 10 year cylinder warranty. Available in 250lt, 315lt, and 400lt models
Whilst suitable for both indoor and outdoor installation, the Rheem electric water heater with dual handed fittings make it more convenient for installation. No matter which way the unit is rotated all the fittings are accessible, making it easier to install into those tight spaces. Available in 25lt-160lt models
RheemPlus® is the perfect choice for new homes or when replacing existing water heaters. RheemPlus® stores water above 60°C yet delivers water not exceeding 50°C so there's no need to install a tempering valve, making installations quicker and easier for the plumber and safer for the home owner. Available in 125lt, 250lt, and 315lt models
Instantaneous heaters, where water is heated on demand and not stored are also available, but are less common. Instantaneous or continuous flow water heaters are designed to deliver a steady stream of heated water for a bath, sink or shower. Each time a tap is turned on, water is heated instantly by electricity and then flows to the outlet.
An Instantaneous electric water heater typically requires high power inputs, particularly if more than one unit is running at once. In some cases three phase power is required, in others single phase power is adequate.
* Replacement of the same or similar, size and energy source system (ie: your existing 50L external electric storage, replaced with a new 50L external electric storage system in the same location). Existing hot water system must be located on the premises in compliance with relevant standards and by-laws. The cost does not include the supply and installation of a tempering valve if required.
