HONEST COMPARISON
Solar Pool Heating vs Heat Pumps: An Honest Comparison for Adelaide Pools
We sell both solar pool heating and pool heat pumps, and they earn us roughly the same, so this comparison has no thumb on the scale. Solar is the most cost effective way to heat your pool provided you have adequate, non-shaded roof space. Heat pumps are a great option if roof space is limited, if you want year-round swimming, or if you have solar PV.
Here’s how they compare on cost, running cost, lifespan and season, drawn from 45+ years of installing both across South Australia.
WHO IT’S FOR
Who this comparison is for
A straight answer for your pool, not a sales pitch for either system.
This page is for you if you:
Are deciding between the two
You’ve heard the arguments both ways and want a straight answer for your pool.
Want to swim year-round
Year-round operation points to a heat pump, typically a larger unit or the Lux V range, plus a thermal cover.
Have limited or shaded roof space
Roof aspect and shading make or break solar. South-facing roofs need 20 to 30% more collector area; heavy shading usually rules solar out.
Have solar PV on the house
Running a heat pump off your own solar PV during daylight makes it dramatically cheaper to run.
The short answer
Choose solar if your roof suits
North, east or west-facing, largely unshaded, with area roughly equal to your pool’s surface. Lowest running cost by far: effectively just your existing pool pump.
Choose a heat pump if it doesn’t
Limited roof, heavy shading, year-round goals or solar PV on the house. Consistent set-and-forget temperatures, typically $30 to $80 per week in season on a covered pool.

OUR METHOD
How we’d decide for your pool
The same five checks we run on every quote visit.
Check the roof
Aspect, shading, available area, structural condition. This decides solar viability before anything else.
Measure the pool
Surface area drives solar sizing; volume drives heat pump sizing.
Define your season
Extended summer, or year-round? Year-round changes the recommendation.
Weigh running cost against upfront
Including whether you have solar PV to run a heat pump from.
Recommend honestly
Sometimes that’s solar, sometimes a heat pump, sometimes both together, and sometimes the cheapest option is the right one.
“We sell solar, heat pumps and DIY kits. They all earn us roughly the same. We recommend whatever genuinely suits.”

FAQS
Solar vs heat pump FAQs
Both have their benefits. Solar is the most cost effective way to heat your pool provided you have adequate, non-shaded roof space. Heat pumps are a great option if roof spaces are limited, or if you have solar PV.
Yes, and it’s a popular choice for the lowest running cost through most of the year plus the option to swim year-round. Solar carries the bulk of the heating whenever there’s sun; the heat pump tops up on cool days and through winter.
South-facing roofs need around 20 to 30% more collector area to compensate for reduced sun exposure. North, east and west all work without adjustment.
Yes, sized correctly. Year-round typically needs a larger unit or a Lux V range unit, plus a thermal pool cover to keep running costs reasonable.
Solar, clearly: the energy that heats the water is free. A heat pump typically costs $30 to $80 per week in season on a covered pool.
Solar: Zane systems carry a 25-year design life, often longer. Heat pumps: up to 15 years for a well-maintained unit.
It helps both equally: a thermal cover roughly halves heat loss, so whichever system you choose performs better with one.
IN PRACTICE
How the choice plays out
Three real-world shapes of the decision.
Solar retrofit, eastern suburbs
Season stretched by months
Heat pump replacing gas, southern suburbs
Year-round with a cover
Solar plus heat pump together
The best of both
BOTH SIDES
Owners of Both, on How Each One Held Up
Some of these customers went solar, some went heat pump, some ended up with both. Here is how each one has held up.
Keep Up the Great Work Guys
"Five stars for Henry and his team. They were great right from the process of provide quote (best price), site visit, equipment installation (modified their standard process to suit my property’s requirements at no extra cost) and, more importantly providing prompt after sales-service.
Everyone was punctual, respectful in behaviour and super helpful with general maintenance tips and advice. Keep up the great work guys."

Worked Without Fault
"Was doing an extension on my property at Unley and was in need of prompt service when building my pool and solar heating. John and his team were contacted, attend onsite and quoted and installed seamlessly and the system has worked without fault.
I have never had a problem in years and would highly recommend the business for anyone looking at solar or pool equipment in general as a first step."

Quality Was Amazing
"These guys just installed a solar heating system at my home in Walkley Heights. The service was great, the installation quality was amazing and the system works like a charm.
If your going to get solar heating use this great south Australian business, we looked at most companies and DIY kits this
system is much much better then we could of thought.
Thanks again."
