Electric hot water systems are a reliable and practical option for homes across Wollongong, Shellharbour, Kiama, Nowra and surrounding Illawarra suburbs.
At Illawarra Hot Water, we supply electric hot water heaters from leading brands including Rheem, Dux, Vulcan and Bosch, with systems available in a range of capacities and configurations.
An electric hot water system uses electricity to heat water, which is then supplied to your taps, showers and appliances when required.
The most common type is an electric storage hot water system. These systems heat water inside an insulated storage tank and keep it available for use.
Electric systems are available in different tank capacities and element configurations, allowing you to select a system based on your household’s hot water requirements.
Some electric systems can also be operated using off-peak electricity, depending on the model, electricity tariff and installation.
An electric storage system heats water using an electric heating element located inside the storage tank. Once heated, the water remains stored and insulated until it is needed.
When a hot water tap is opened, heated water leaves the tank and cold water enters to replace it. The heating element then heats the incoming water so the system can maintain its hot water supply.
An instantaneous electric system heats water as it passes through the unit rather than storing a large volume of heated water in a tank.
When a hot water outlet is opened, water flows through the heating unit and is heated before reaching the tap. This type of system can provide a compact solution where space is limited, although the system needs to be appropriately sized for the required water flow.
Electric storage systems maintain a supply of heated water ready for household use, making them a familiar solution for everyday hot water needs.
Electric storage systems maintain a supply of heated water ready for household use, making them a familiar solution for everyday hot water needs.
Storage systems are available in different tank sizes, allowing you to select a capacity appropriate for your household and expected hot water demand.
Electric systems can be suitable for a variety of residential applications, subject to the property’s existing electrical, plumbing and installation requirements.
You can choose between traditional storage systems and instantaneous systems depending on your available space and hot water usage.
Electric systems use established heating technology and can provide a simple solution for homes requiring a dependable hot water supply.
A wide range of manufacturers, models, capacities and configurations are available, making it easier to compare systems based on your property’s requirements.
An electric hot water system can be a practical choice for many homes, but the right system depends on how your household uses hot water and the requirements of your property.
The number of people living in your home is one of the main factors when selecting a storage capacity. Larger households generally require more available hot water than smaller households.
Consider how often your household uses showers, baths, kitchen taps, washing machines and other hot water outlets. High usage during the same period can increase the required system capacity.
Storage systems require sufficient space for the tank and associated connections. If space is restricted, an instantaneous system may be worth considering where the electrical supply and application are suitable.
Your existing electrical supply, plumbing, installation location and current hot water system can all influence which electric system is appropriate.
The purchase price is only one part of choosing a hot water system. Consider the system’s capacity, energy consumption, expected usage and long-term operating costs when comparing your options.
If you’re replacing an existing system, a like-for-like replacement may not always be the best option. Changes in household size, usage or energy requirements may mean another capacity or system configuration is more suitable.
Choosing the correct capacity is important for ensuring your household has enough hot water when it is needed.
For electric storage systems, capacity is generally considered alongside household size and typical daily hot water consumption. As a general guide:
These figures are only a general starting point. Actual requirements can vary depending on shower frequency, number of bathrooms, household routines, water usage and peak demand.
When selecting an electric storage system, consider:
For instantaneous electric systems, sizing works differently because the required output depends on water flow and the electrical supply available to the property.

The service life of an electric hot water system depends on factors such as the model, installation, water quality, maintenance and frequency of use. When a system reaches the end of its serviceable life, replacement may be more practical than continued repairs.
The appropriate size depends on household numbers, hot water usage, the number of bathrooms and your typical peak demand. Storage systems are available in different capacities, while instantaneous systems are sized according to their required flow and electrical capacity.
Running costs depend on the system’s efficiency, capacity, electricity tariff, household usage and how frequently the water needs to be heated. Comparing expected energy consumption and operating conditions is important when selecting a system.
A storage system heats and stores water in a tank, while an instantaneous system heats water as it passes through the unit. Storage systems are available in a broad range of capacities, while instantaneous systems can provide a compact alternative where the electrical supply and application are suitable.
In many cases, an existing hot water system can be replaced with an electric system, but suitability depends on the property’s electrical supply, plumbing, installation location and required capacity.
Frequent breakdowns, inadequate hot water, leaks, corrosion, unusual operation or an ageing system can indicate that replacement should be considered. A professional assessment can help determine whether repair or replacement is the better option.
Hot water consumption varies significantly between households. Shower frequency, shower duration, number of occupants, bathrooms, appliances and daily routines can all affect demand, which is why system capacity should be selected according to actual household requirements.
Different homes have different hot water requirements. The right system depends on factors such as household size, daily hot water usage, available energy sources, installation requirements and running costs.
Electric storage systems are a familiar and practical option for many Australian homes. They are available in a range of capacities to suit different household requirements.
Gas hot water systems can provide reliable hot water and are available as both storage and continuous flow systems.
Solar hot water systems use energy from the sun to heat water and can help reduce reliance on conventional energy sources.
Heat pumps use heat from the surrounding air to heat water efficiently. They can be an excellent option for households looking to improve energy efficiency.
