1. Description
Welcome to Highland Koi Ltd, your trusted source for premium swimming pool heat pumps. With our extensive industry experience, we've harnessed our knowledge to craft a distinctive range of swimming pool heat pumps.
Introducing the cutting-edge Thermotec Inverter Pro Vertical series of pool heat pumps, setting a new benchmark for efficiency, performance, reliability, and whisper-quiet operation. These latest models feature a refreshed case design and an updated color palette for a contemporary appearance.
The Thermotec Inverter Vertical series operates with full inverter precision, continuously adapting fan and compressor speeds to align with your pool's heating requirements. This dynamic control empowers the Thermotec Inverter Pro Vertical to deliver significantly reduced operational costs, showcasing impressive COPs (Coefficient of Performance) of up to 13. This translates to an astounding 13kw of heat delivered to your pool for every 1kw of electricity consumed, resulting in substantial savings compared to other heat pump options.
Additionally, the inverter technology in these models reduces the electrical startup demand, making them an excellent choice for properties with sensitive or constrained electrical supplies.
These heat pumps boast larger evaporators (fins), offering an expanded surface area for efficient heat extraction even at lower air temperatures. This exceptional feature makes the Thermotec Inverter an ideal selection for koi ponds and indoor pools used year-round, ensuring heightened efficiency and lower operating costs throughout all seasons.
 
2. COP And Performance
The Thermotec Inverter leverages cutting-edge inverter technology to outperform traditional on/off heat pumps and many other inverter-driven models. These heat pumps continue to deliver exceptional heating even as external temperatures drop, operating efficiently in conditions as cold as -15°C.
The COP (Coefficient of Performance) serves as a measure of the heat pump's efficiency, indicating the ratio of heat delivered to electricity consumed. With the advanced inverter technology, the Thermotec Inverter achieves impressive COPs of up to 20.04. This means that under specific conditions, 1kw of electricity results in an extraordinary 20.04kw of heat output to your pool.
The Thermotec Inverter series is classified as class A energy-efficient, boasting COP ratings of 5 or higher and receiving TUV testing approval in Germany. These exceptional COP ratings reach as high as 20.04, underscoring the remarkable performance of these heat pumps.
 
3. Extremely Quiet Operation
The Thermotec Inverter range operates with near-silent efficiency, thanks to a unique internal ventilation system and the advanced inverter technology. Both the fan and compressor automatically adjust their speeds to align with your pool's heat demand. As your pool reaches the desired temperature, the unit runs with reduced power consumption and minimal noise.
 
4. Color Touch Screen Controls
Fitted with a distinctive color backlit touch screen control/display panel, the Thermotec Inverter heat pumps offer user-friendly controls. The display provides vital information, including the current pool water temperature, operating mode (heating or cooling), timer status, fan operation, time and date, outside ambient temperature, and fault codes if relevant. It also features graphical representations of the pool temperature and power consumption over time.
 
5. Wi-Fi Control
For added convenience, we provide an optional Wi-Fi module that enables remote monitoring and control of the Thermotec Inverter from your smartphone or any web browser. The module is available in two versions and connects effortlessly to your heat pump, enhancing technical support capabilities and expediting issue resolution.
The Aqua Temp app, compatible with both Android and iPhone, grants you the ability to:
Turn the heat pump on and off
Monitor the current pool water temperature
Adjust the desired pool set temperature
Set timers
View the pool temperature history graph
Change the heat pump mode (heating, cooling, or auto)
Activate or deactivate silence mode for nighttime use
Access weather temperature and information
Display error codes and messages
Please ensure a robust Wi-Fi signal at the heat pump's location or consider signal boosters if required.
 
6. Thermotec Inverter 3G/4G Mobile Data Module (DTU)
For areas lacking Wi-Fi coverage near the heat pump, we offer a 3G/4G mobile data module. This module connects to the 3G/4G mobile data network, enabling control via the Aqua Temp app on your smartphone. It's a perfect solution for locations without Wi-Fi coverage near the heat pump's placement.
 
7. Installation
Installation is straightforward, and we offer installation advice and services if required. We recommend installing a bypass kit to facilitate winter drainage when the heat pump is not in use. Find installation guidance in our Installation Tips pages, view photographic examples of pool heat pump installations in our Photo Gallery, and consult our FAQ pages for additional information.
 
8. Multiple Heat Pump Installation
For larger pools requiring increased capacity, consider installing multiple heat pumps to ensure your pool gets the necessary heating capacity.
 
9. Availability
Our range of Thermotec Inverter pool heat pumps is readily available in the UK, with convenient 1 – 3 day delivery service to any UK address.
 
10. Delivery
