*Measured under standard UK seasonal outdoor operating conditions at 26°C target water temperature.

Year-Round Heating Down to -15°C The Fairland InverX Horizontal heat pump range delivers reliable swimming pool heating across all four seasons. Designed to extract thermal energy from outdoor air in temperatures as low as minus 15 degrees Celsius, this heat pump maintains ideal water temperatures for swimming pools, swim spas, hot tubs, and large koi ponds throughout the UK spring, summer, autumn, and winter.

Three Versatile Operating Modes Using Fairland patented TurboSilence full inverter technology, the InverX offers three user selectable heating modes:

Booster Mode: Delivers a 120 percent heating boost to warm cold pool water quickly at startup.
Smart Mode: Automatically adjusts output between 20 percent and 100 percent capacity for efficient daily temperature maintenance.
Silence Mode: Operates quietly between 20 percent and 80 percent capacity, making it an average of 10 times quieter than standard pool heaters.

Soft Start and Digital Touchscreen Security Every unit incorporates soft start electrical technology, eliminating power spikes on startup and protecting sensitive home consumer units. The digital LCD touchscreen control panel features a screen lock function, making it easy to prevent unauthorized temperature changes in holiday lets or rental properties. Integrated Wi-Fi control allows you to alter pool temperatures and review performance remotely using your smartphone.

Titanium Heat Exchanger and Standard Accessories Built to withstand salt chlorination systems and chemical dosing, the internal titanium heat exchanger is completely corrosion proof. Each unit ships complete with anti vibration mount pads, hydraulic and electrical quick connections, a water flow indicator, and a custom fitted winter protection cover.

Tiered Long Term Warranty Package

3 Year Comprehensive Parts Warranty: Covers all internal electronics, sensors, fan motors, and control valves.
10 Year Compressor Warranty: Guarantees performance and reliability for the Mitsubishi twin rotary inverter compressor.
12 Year Titanium Heat Exchanger Warranty: Offers long term protection against corrosion and thermal fatigue.

Frequently Asked Questions

What warranty cover comes with the Fairland InverX Horizontal range?

Every InverX Horizontal heat pump comes with a tiered manufacturer warranty: 3 years on all components and parts, 10 years on the twin-rotary compressor, and 12 years on the titanium heat exchanger.

What accessories are included in the box?

Each unit comes supplied with a fitted winter protection cover, anti-vibration rubber mounting pads, a water flow indicator, and 50mm hydraulic union connectors.

Why is soft-start technology important?

Soft-start technology gradually ramps up electrical current when the heat pump turns on, preventing power surges that can trip domestic circuit breakers in home plant rooms.

Can the control panel be locked?

Yes. The digital touch screen control panel includes a built-in locking feature, preventing guests or unauthorized users from changing the temperature setpoint in holiday rentals or commercial facilities.
