Adelaide summers are hot and dry. A pool can either be a major energy drain or remarkably efficient — design choices made at build time set the lifetime running cost. This guide covers the design and equipment decisions that have the biggest impact.
Pool size and depth
Larger pools cost more to heat, more to filter, more to chlorinate, and more to maintain. The smallest pool that meets your actual swimming needs is the cheapest to run. A 6m family pool is much cheaper to run than a 10m pool — and for many families a 6m–7m pool covers everything they actually use it for.
Thermal cover
The single highest-impact running-cost decision. Without a cover, a heated pool loses much of its heat overnight through evaporation; a good thermal cover keeps far more of it in. Specify a thermal cover at build time — manual or automatic-reel — for the lowest lifetime running cost.
Variable-speed pump
VS pumps run at the lowest speed that maintains adequate filtration, typically drawing much less power than a fixed-speed pump. Check the pump’s energy rating label, and make sure your quote specifies a quality unit from an established brand rather than the cheapest available.
Heat pump over gas (for shoulder months)
Electric heat pumps deliver 4–5 units of heat per unit of electricity input. Gas delivers 0.85 units per unit of input cost. Over 7 months of shoulder + summer use, the heat pump saves $1,200–$2,800/year vs gas. Gas is best for occasional ‘boost’ heating, not primary heat.
LED lighting
LED pool lights draw far less power than the old halogen lights for similar brightness, and last much longer. All new builds default to LED.
Solar pool heating + thermal cover combo
Solar collectors plus a thermal cover is effectively free pool heating for 9 months of the year in Adelaide. Roof aspect dependent — north-facing pitched roofs are ideal. Combined with a heat pump as winter backup, this is the gold-standard energy-efficient setup.
Specify on quote
Tell your builder you want energy-efficient defaults. Quotes can show the running-cost difference between basic and efficient builds — and over 10 years the difference adds up.
