Overview
Why choose the Electroheat Ultra
The Electroheat Ultra range is engineered for cold climates. Hot-gas de-icing clears frost from the unit automatically, so it keeps heating efficiently when temperatures drop — where a standard heat pump would struggle. It draws heat from the air to keep your pool warm through the coldest months, making true year-round swimming possible in cooler regions.
True year-round heat
Keeps your pool warm through the coldest months for genuine year-round swimming in cooler regions.
Efficient heat-from-air
Draws free heat from the air all year — far less energy than gas or electric heating.

The technology
How a pool heat pump works
A heat pump doesn’t burn fuel to make heat — it moves it. It draws warmth from the air and concentrates it into your pool, using a fraction of the energy of gas or electric heating.
Draws heat from the air
A fan pulls outside air across the evaporator, where refrigerant absorbs the latent heat — even on cool days.
Compressor raises the heat
The compressor concentrates that warmth to a much higher, usable temperature.
Transfers it to your water
Pool water passes through the titanium heat exchanger and picks up the heat from the refrigerant.
Warms the pool, then repeats
The warmed water returns to the pool and the refrigerant cycles back for more — around the clock.
Choosing a model
Standard inverter or Ultra?
If your winters are mild, a standard inverter heat pump may be all you need. The Ultra earns its place in colder regions.
Standard inverter
Mild to temperate climates
An inverter model such as the ECO-V heats efficiently and holds temperature well in most Australian conditions.
Electroheat Ultra
Cold & frost-prone climates
Hot-gas de-icing keeps the Ultra heating reliably through frost and cold, where output on a standard unit would drop.
What's in the system
Key components
- 01
Titanium heat exchanger
A dual-coil titanium exchanger transfers heat to your water and resists salt and chlorinated water for a long service life.
- 02
Cold-climate compressor
Paired with hot-gas de-icing to keep delivering heat efficiently in cold, damp conditions.
- 03
Blue-fin evaporator
A large, hydrophilic blue-fin evaporator captures more heat from the air and adds corrosion protection — ideal for coastal sites.
- 04
Smart control
Set-and-hold temperature control for dependable year-round operation.
- 05
Weatherproof cabinet
A UV-resistant, sound-dampened cabinet rated for outdoor installation keeps operation quiet and durable.
Tailored to your pool
Installation, step by step
1
Site assessment
Your Zane dealer checks the equipment area for airflow clearance, a level base and suitable power, plus the run to your pool’s plumbing.
2
Sizing to your pool
The unit is sized to your pool volume, climate, how you use it and whether you run a cover — so it’s neither under- nor over-powered.
3
Professional installation
Trained technicians connect the plumbing and power, commission the unit and set it up on the control panel or app.

Keep airflow clear
Keep the space around the unit clear of leaves and obstructions so it can breathe and run efficiently.
Annual service
A yearly check by a qualified technician keeps the unit running at peak efficiency and catches anything early.
Pool chemistry & a cover
Balanced water protects the titanium exchanger, and a pool cover markedly cuts running costs, especially in cooler months.
