Thermotec Inverter Heat Pump for Koi Ponds

The Thermotec Inverter range of pool heat pumps really do offer the best in terms of efficiency, performance, reliability and low noise operation.

The Thermotec Inverter range are fully inverter driven. This means that they automatically adjust the speed of the fan and compressor to precisely match the heat demand from the pond.

The ability to adjust the output of the heat pump allows the Thermotec Inverter to deliver greatly reduced running costs with COPs of up to 13. This means that for every 1kw of electricity used by the heat pump, 13kw of heat is delivered to the pool. This delivers reduced running costs compared with other heat pumps on the market.

In addition the inverter technology has a reduced electrical startup requirement, making them ideal for properties with a sensitive or limited electrical supply.

COP And Performance

By using the latest inverter technology, the Thermotec Inverter can out perform traditional on/off type heat pumps as well as many other inverter driven models.

Even as the outside air temperature falls, the Thermotec Inverter will still perform well, delivering heat to your pool.

The Thermotec Inverter heat pumps can work well with outside air temperatures as low as -15c

The COP (Coefficient of Performance) is the ratio of the amount of heat (in kw) that the heat pump delivers to your pool compared to the electricity that the heat pump uses (in kw)

By using the latest inverter technology, the Thermotec Inverter has COPs up to 13.6. This means that in these conditions, 1kw of electricity consumed by the heat pump will output 13.6kw of heat to your pool !

Extremely Quiet Operation

The Thermotec Inverter range work very silently thanks to a unique internal ventilation system and the inverter technology.

Both the fan and compressor automatically adjust their speed to match the pool heat demand, therefore once the pool is up to temperature, the unit can operate with reduced power consumption and noise.

Colour Touch Screen Controls

The Thermotec Inverter have a unique 7 inch colour backlit touch screen control/display panel

The display will show:-

In addition, the display can show:-

A graph of the temperature of the pool over time so that you can see how the pool temperature is being maintained by the Thermotec Inverter heat pump. A graph of the power consumed by the heat pump over time. The colour display is backlit making it easy to read in low light conditions and also in bright sunlight.

Wi-Fi Control

The optional Wi-Fi module allows the Thermotec Inverter to be monitored and controlled from a smartphone or any internet web browser.

Using the app you can:-

Note: A a wifi signal is required at the location of the heat pump in order for the wifi module to be able to connect to your wifi. Please test the strength of the wifi signal eg with a laptop or your smart phone before purchasing the wifi module.
