1. Product Overview
At Highland Koi Ltd, we are proud to introduce the new Thermotec Inverter Pro Horizontal range of pool heat pumps, designed to offer exceptional efficiency, performance, reliability, and quiet operation. These state-of-the-art heat pumps are fully inverter-driven, automatically adjusting fan and compressor speeds to precisely meet your pool's heat demands. This innovative technology significantly reduces running costs, achieving COPs of up to 13, which means you get 13kw of heat for every 1kw of electricity used.
The Thermotec Inverter Pro Horizontal models are ideal for properties with sensitive or limited electrical supplies, thanks to their reduced electrical startup requirements. Their larger evaporators provide superior heat extraction at low air temperatures, making them perfect for year-round use, especially for koi ponds and indoor pools, resulting in higher efficiency and lower running costs.
 
Available Models:
Thermotec Inverter Pro 9kW, 12kW, 17kW, 20kW – Single Fan, Horizontal
Thermotec Inverter Pro 24kW – Twin Fan, Horizontal
We also offer the Thermotec Inverter Pro Vertical fan in 29kw single-phase and 34kw single and 3-phase models. Please click here for more details and pricing.

5. COP And Performance
The Thermotec Inverter uses cutting-edge inverter technology to outperform traditional heat pumps and many other inverter-driven models. It excels even as outdoor temperatures drop, with the ability to operate effectively down to -15°C. The high COP (Coefficient of Performance) of up to 13.6 ensures exceptional heat output compared to electricity consumption.
 
6. Extremely Quiet Operation
Thanks to a unique internal ventilation system and inverter technology, the Thermotec Inverter range operates silently. The fan and compressor adapt their speeds to match pool heat demands, reducing both power consumption and noise when the pool reaches its desired temperature.
 
7. Color Touch Screen Controls
The Thermotec Inverter boasts a 5-inch color backlit touch screen control panel, providing intuitive controls. The display shows vital information, including current pool water temperature, mode (heating/cooling), timer settings, fan status, time and date, outside ambient temperature, and fault codes if applicable. Graphs of pool temperature and power consumption over time are also displayed.
 
8. Wi-Fi Control
Included is a FREE Wi-Fi module that enables remote monitoring and control via a smartphone or web browser. The module connects easily to your heat pump, enhancing technical support speed and efficiency. With the app, you can turn the heat pump on/off, adjust temperature settings, set timers, change operating modes, and access detailed information.
