If you have a swimming pool, your pool's pump unit could be responsible for 20–30% of your energy bill. This would make it one of the largest users of electricity in your home. By making smart purchasing decisions and following our helpful operating tips, you can reduce your pool energy costs and still enjoy your swimming pool.
The energy rating label helps you to compare the energy efficiency and running costs of different pool pumps. To improve your household's energy efficiency, buy a pool pump that is participating in this voluntary labelling scheme, with a minimum of 5 stars. The highest efficiency models now carry a rating of 8 stars, with every star representing an additional 20% saving in energy costs. The more stars, the more energy efficient the pool pump will be, and the lower the running costs.
Compare the star ratings at the top of the energy rating label on the pump models, then use the number in the energy consumption box to find out the pool pump’s annual energy consumption. This figure is based on pumping 50,000 litres of water per day. Buying a high efficiency pump may cost a little more initially, but the energy savings will pay off in the long run.
The larger the pump, the greater the pumping and maintenance costs. Consult your pool pump supplier to make sure your pump is not oversized.
Pumps with the highest star ratings are likely to be multi-speed pumps, because they are often more efficient and use less energy than single-speed pumps. This is because they run slower for filtering, which uses less energy, but can be sped up to run pool cleaning equipment, which uses more energy. It is important to ensure the pump will work effectively with your filter pump and any cleaning equipment on these settings. You may also need to adjust the times you operate the pump to ensure you filter enough water each day.
The table below shows the annual running costs for pool pumps based on their star rating.
|Energy star rating||Annual energy cost*|
*Based on pumping 50,000 litres of water per day and electricity tariff of 28c/kWh.
Regardless of the type of pool pump you own, you can reduce your energy bills by running it efficiently.
Energy rating labels help you compare appliances so you can and choose the most energy and water efficient, and save money on running costs.
The Energy Rating Calculator and app allows you to calculate the energy consumption and running costs for an appliance before you buy it.
