Pool Heat Pump Sizing Calculator: Get a Directional Answer in 30 Seconds
Use this free calculator to get an approximate sizing recommendation for a pool heat pump on your Adelaide pool. Enter your pool dimensions, target temperature and target swim months, and get a recommended heat pump capacity (kW) and matching Guardian range.
The calculator uses the same sizing methodology Beasley’s team applies during quoting, drawn from 45+ years of installations across South Australia. Results are directional. A free quote with our friendly team confirms the final specification based on your pool, equipment area and electrical setup.
IS THIS THE RIGHT TOOL FOR YOU?
Who This Calculator Is for
A quick, free way to get a directional answer on heat pump sizing before you talk to anyone.
This tool is for you if you:
Are researching and sizing a heat pump
Get a realistic kW capacity for your pool before you start comparing quotes or models.
Are preparing for a quote conversation
Walk into your free consultation with a directional number already in hand.
Are weighing up year-round swimming
Year-round operation changes the sizing. The calculator recognises it as a target and adjusts accordingly.
Worth knowing before you calculate:
Electrical requirements aren’t covered
Single-phase versus three-phase and switchboard capacity aren’t part of the calculator. These are confirmed during the phone consultation, and any electrical work is included in your fixed-price quote.
Unusual or commercial pools
The calculator factors heat loss assumptions for typical pool construction. Unusually constructed or commercial pools may need different sizing, so get in touch directly for a tailored discussion.

For guidance only. It uses the same sizing methodology our team applies during quote building. It’s a starting point rather than a substitute for working through your specific needs. Our knowledge and experience in dealing with all factors such as specific pool construction, equipment area, and electrical setup will give you the most accurate quote. Call us today.
For a properly sized inverter heat pump on a covered Adelaide pool, running cost is typically $30 to $80 per week in peak season to maintain swimming temperature. Running cost depends on size, target temperature, pool cover use, and swim usage. The calculator gives a range based on your inputs.
This is case by case dependent. Bigger units can heat your pool more efficiently, and do not have to work as hard to maintain consistent temperatures. The calculator gives the right-sized recommendation for your sized pool. Call our friendly team to achieve your goals.
Yes, pool cover is a key input. A thermal pool cover dramatically improves the efficiency of the heat pump. The calculator adjusts accordingly.
The calculator recognises year-round as a target and sizes the heat pump accordingly. Year-round operation typically requires a larger unit, or a unit from the Lux V range, or potentially multiple heat pumps, plus a thermal pool cover to keep running costs reasonable.
Calculate the approximate rectangular volume enclosing the pool. For a more accurate measurement, get in touch. We can use aerial photography to accurately measure the dimensions of your pool.
No. The calculator is free, takes about 30 seconds, and doesn’t ask for an email address or any contact details.

What Owners Say About Getting the Size Right
An undersized heat pump never quite gets there and costs more to run. These customers had theirs sized on site.
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."
