Inverter Heat Pumps
PV Solar Compatible Pool Heating

Enjoy a comfortable pool for longer, while keeping running costs down.

We install inverter heat pumps from Oasis, our trusted distribution partner, including the Oasis IX Series. Designed to work alongside your PV solar system, these efficient heat pumps help make the most of the energy your solar panels produce, providing lower-cost and more sustainable pool heating for you and your family.

COP of up to 20

Coefficient of Performance (COP) measures efficiency — our Oasis inverter heat pumps deliver up to 20kW of heat for every 1kW of electricity consumed. That's a massive reduction in running costs compared to gas or direct electric heating.

Quiet Inverter Operation

Modern inverter heat pumps run at reduced speeds when the pool is near temperature, meaning quiet, efficient background operation — not the loud on/off cycling of older fixed-speed units.

Year-Round Heating Capability

Our recommended heat pumps operate effectively down to 5°C ambient air temperature, making them suitable for year-round pool heating across Melbourne's climate.

Works with Rooftop Solar PV

Schedule your heat pump to run during peak solar generation hours and effectively heat your pool for free using electricity from your own rooftop panels.

All Major Brands Serviced

We service all major brands, including Oasis, Madimack, Hurlcon, Rheem and Hayward.

Frequently Asked Questions

How much does a pool heat pump cost to run?

Running costs vary depending on the pool size, target temperature and ambient conditions. As a rough guide, a quality inverter heat pump heating an average 50,000L pool in Melbourne typically costs $50–$150/month to run — significantly less than gas heating.

What size heat pump do I need for my pool?

Sizes are 9kW to 28kW on a single phase and 28, 32 and 36kW options on three phases. Use the calculator above for an estimate, or book a call and we'll confirm the right size for your pool.

How long does a pool heat pump last?

Quality inverter heat pumps are designed to last 10–15 years or longer with proper maintenance. Regular servicing helps maximise the lifespan and efficiency of your system.

Can a heat pump heat my pool in winter?

Yes — modern inverter heat pumps operate effectively in ambient temperatures as low as 5°C, which covers Melbourne winters well. On very cold days, the heat pump works harder and less efficiently, but it will still maintain your set pool temperature.
