Maximum Power. Minimum Cost.
The heavyweight champion of our range. Designed for larger spas and colder climates, it combines immense 12kW heating power with an upgraded winter protection system, ensuring your hot tub stays ready even in the deepest freeze.
Pay 1kW. Get 16kW.
This is our most efficient unit yet. By utilising a larger compressor and advanced air capture, the OL12HP can multiply your electricity input by up to 16 times. You pay for a fraction of the power, but get 100% of the heat.
PTC Winter-Safe System
Built for the extreme cold. Unlike smaller models, the OL12HP features a dedicated Bottom Plate Heater (PTC). This smart element actively prevents ice build-up in the tray, allowing the unit to run smoothly even when it's -12°C outside.
Whisper Quiet Technology
Big power doesn't mean big noise. Thanks to the DC Inverter fan, this unit ramps its speed up and down gently. It maintains a peaceful acoustic profile (approx 55dB), ensuring your garden stays tranquil.
Summer Refresh Mode
Perfect for heatwaves. With a simple mode switch, the OL12HP reverses its cycle to actively cool your water, transforming your hot tub or swim spa into a refreshing cool-down tank.
Universal Fit (Swim Spas Ready)
Designed for larger volumes. Whether you have a large 6-seater hot tub or a swim spa, the 12kW capacity ensures rapid heating recovery and integrates seamlessly with your existing filtration.
