Types of electric hot water systems

According to Sustainability Victoria, there are two common types of electric hot water systems to consider based on your needs.

Storage Hot Water Systems

In storage hot water systems, the water is heated using electric elements and kept in an insulated tank until needed. The systems are made to work at a range of pressures, including the more typical mains pressure and the less typical gravity-fed pressure. Moreover, they are available in various sizes. Also, some systems use off-peak electricity to heat water at night, minimising energy costs. They also have a boost element for additional heating as needed.



  • Provides a steady, ready-to-use supply of hot water throughout the day.
  • By using off-peak electricity pricing, larger systems may be more economical during certain hours.
  • Tanks can be placed indoors or outside, depending on available space.
  • Adelaide hot water system is available in a range of sizes to accommodate the needs of different types of households, including small apartments and large family homes.


  • Even when hot water isn’t being pulled, energy is still used since heat is lost through the tank walls. Smaller families, where the percentage of wasted heat is larger than the usage, may find this to be very expensive.
  • Requires enough room for the tank; thus, small places might not be the best fit.
  • In general, these systems are more expensive upfront than tankless systems, particularly for larger tank variants.
  • Make necessary routine maintenance to guarantee effective functioning and to stop problems like corrosion or silt buildup.

Instantaneous Hot Water System

Instantaneous hot water systems, often referred to as tankless systems, are a type of electric hot water system that heats water immediately without the need for a storage tank. Equipped with a powerful electric element, this heats the cold water as soon as it is demanded—whether cold water is entering through a pipe or a hot water tap is turned on. This efficient process ensures you have a steady supply of hot water, helping you keep track of electric hot water system prices Adelaide without the need for storing hot water.



  • Since a heated tank does not need to be maintained, these systems avoid the energy losses associated with storage systems. Wherein this could lead to a decrease in the amount of energy used in comparison to traditional storage systems.
  • These devices are compact and don’t require a large space for a tank. They are ideal for little homes or apartments.
  • This unit ensures that you never run out of hot water by providing it on-demand as long as the system is operating at maximum capacity.
  • Tankless systems are usually less prone to corrosion and sediment buildup, and they typically have a longer lifespan than tank systems.


  • Although instantaneous systems minimise operating expenses, they may still initially cost more to buy and install than a traditional tank system in the hot water Adelaide market.
  • With this system, you may find it difficult to provide enough hot water for many purposes at once, such as running the dishwasher and having a shower. This is because the heater is operating at its maximum flow rate.
  • Unless they are augmented by a renewable energy source, such as solar panels, operating costs might be higher during periods of use because they frequently operate on peak electricity rates.
  • It may require modifications to plumbing and electrical systems and requires professional installation, especially in homes upgrading from a tank system.

Benefits of electric hot water systems in Adelaide
