Electric Water Heater Power Consumption

There are a variety of online tools you can use to calculate your electric hot water system power usage. This handy tool from the South Australian Government will help you get an estimate of all types of consumption (for both gas and electric heaters).

In fact, most brands have helpful calculators that can give you an even more accurate estimate of energy consumption. This tool from Rheem can help give a running cost estimate on all the different models of Rheem heaters.

Obviously, the make and model of your heater will affect the running cost. Before using an alternative tool, Google the brand and see if they have a running cost calculator on their website. Make sure you cross-check it with the government-run tools to get an unbiased comparison.

There is another tool from Sustainability Victoria that you can use to calculate electric hot water system power usage. Their estimates are affected by the energy star rating of the heater — that’s an important thing to take into account when you are choosing a heater.

Energy Ratings for Water Heaters

The energy rating label on your water heater is an indication of how efficient it is. Most products are assigned between one and six stars. The more stars your heater has, the more efficient it is.

The stars are given in relation to how efficient your model is in relation to other models of the same size. There will also be a sticker with an estimated usage of KW per year.

Look for a water heater with a good energy rating to reduce your power bills and minimise your impact on the environment. There are many factors that influence your choice of heater, but the energy rating should be high on the list.

The initial cost of a highly rated heater might be slightly higher than another, but it’s important to remember that it will save you money down the track.

For more information about energy ratings for water heaters (and a bunch of helpful fact sheets) take a look at the Energy Rating website.

Storage vs Instantaneous Electric 

As a general rule, instantaneous electric heaters are more energy efficient than storage heaters. This is because storage heaters need a constant amount of resting energy to maintain the temperature of the tank.

This is different to an instantaneous system where heating energy is only used when it is required.
