With the mid-winter chill well and truly settling over Adelaide, energy bills are landing in mailboxes across the state. Naturally, most households are looking for clever ways to trim their power consumption. While you might have already turned down the heater or switched to energy-efficient appliances inside, there is one major energy guzzler lurking right in your backyard that many homeowners completely overlook: the pool pump.
A common misconception among pool owners is that your pool requires the exact same treatment in June and July as it does in January. Leaving your pool equipment running on its peak summer settings during winter is essentially throwing money directly down the drain.
The good news? Winter is actually the easiest time to slash your pool’s running costs without sacrificing water quality. Here is how you can optimise your setup to keep your electricity bills low and your water crystal clear all winter long.
1. Adjust Your Pump Timers (The Easiest Win)
During the scorching Adelaide summer, your pool pump needs to run for roughly 8 to 10 hours a day to properly circulate water, distribute chemicals, and filter out high levels of organic debris.
In winter, the pool layout changes dramatically:
-
The sun is lower, meaning UV rays aren’t destroying your chlorine as quickly.
-
Swimmers aren’t introducing bacteria or sunscreen into the water.
-
Algae growth slows right down in cooler water temperatures.
Because of this, you can safely scale your filtration time down to 4 to 6 hours per day. Halving your pump’s running time instantly slashes its energy consumption by 50% for the season.
2. Take Advantage of Off-Peak Tariffs
If you are on a time-of-use electricity tariff, timing is everything. Running your pool pump during peak afternoon periods (when everyone gets home and turns on their household heating) can cost significantly more per kilowatt-hour.
By shifting your timer to run your pool filtration during off-peak windows—such as late at night or mid-morning when solar generation is high across the SA grid—you take advantage of cheaper energy rates.
3. Upgrade to an Eco-Friendly Variable Speed Pump
If you are still running an old, single-speed pool pump, it operates like a car that only knows how to drive at 100 km/h. It consumes maximum power every single second it is switched on, even when it doesn’t need to.
Modern Variable Speed Pumps are the ultimate energy savers. Because water resistance drops dramatically at lower speeds, running a variable speed pump on a lower, quieter setting for a slightly longer duration uses a fraction of the electricity. In fact, making the switch can reduce your pool pump’s running costs by up to 70%, paying for itself in electricity savings over time.
4. Don’t Waste Money Over-Chlorinating
Just as your filtration needs drop in winter, so do your chemical needs. If your salt chlorinator or automated system is still pumping out chlorine at its summer output level, you are wasting energy, wearing out your salt cell prematurely, and over-sanitising the water.
Turn your chlorinator output down to a lower winter setting. You want just enough output to maintain a healthy baseline balance, protecting your pool investment without running up your bill.
