Most Perth pools sit unused for more than half the year. A pool heat pump draws free warmth from the air and moves it into your water, so you can swim from early spring through late autumn without gas or element-heater running costs.
Key Takeaways

How Does a Pool Heat Pump Work?
A pool heat pump works like an air conditioner in reverse. It pulls warmth from the outside air, concentrates it, and transfers it into your water through a titanium heat exchanger.
Madimack’s inverter models deliver a COP of up to 16.4, so most of your heat is effectively free (Madimack), and the compressor holds your set temperature quietly instead of clunking on and off.
What Size Pool Heat Pump Do You Need?
An undersized unit runs flat out without ever holding temperature. Madimack’s residential range spans roughly 10 kW to over 30 kW (Madimack), and we size on four factors:
Factor | Why it matters |
Pool volume | More litres means more heating capacity needed |
Target temperature | Most families swim happily at 26 to 28 degrees |
Season length | Swimming into winter needs more capacity than spring to autumn |
Wind and shade | Exposed, uncovered pools lose heat faster |
A pool cover is the cheapest upgrade you can make. It cuts evaporation, where most pool heat escapes.
What Does a Pool Heat Pump Cost to Run in Perth?
Running costs depend on when you heat, not just how much. On Synergy’s Midday Saver plan, electricity is 8.85 cents per kWh between 9 am and 3 pm, against 55.33 cents in the evening peak (Synergy, 2026).
Madimack’s inverter technology also uses up to 80% less energy than a traditional electric element heater. Exact costs vary with pool size and season, so treat any figure as an estimate; we’ll give you realistic numbers when we quote.
The same midday logic applies to what a heat pump hot water system costs to run in Perth.
What's Involved in Installing One?
Installation is usually a single day. The unit needs a stable pad near your pool equipment, clear airflow, and a licensed electrician for the power connection. We handle the lot as CEC-accredited installers with WA licences PL10691 and GF22501, set up the WiFi app, and walk you through the settings.

Frequently Asked Questions
How long does a pool heat pump take to heat a pool?
From cold, expect a few days to reach set temperature, then it simply maintains it. Time depends on pool volume, unit capacity, weather and whether you use a cover.
Can I run a pool heat pump off solar panels?
Yes, and it’s a strong match. Running through the middle of the day soaks up the solar power your home isn’t using, cutting your effective cost to very little on sunny days.
Do pool heat pumps qualify for rebates?
No. Small-scale technology certificates apply to hot water heat pumps, not pool heating. If anyone quotes you a “pool heat pump rebate”, ask exactly what scheme they mean.
