1. Description

HeatPumps4Pools are the leading specialist supplier of swimming pool heat pumps. We have many years of experience in the market and have used our expertise to research and design our own range of swimming pool heat pumps.

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

The New Thermotec Inverter Horizontal 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 pool.

The ability to adjust the output of the heat pump allows the New Thermotec Inverter Pro Horizontal 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.

They have larger evaporators (fins) which gives more surface area to extract heat at low air temperatures. This allows the Thermotec Inverter to produce more heat than competitor heat pumps at low air temperatures, making them the best choice for koi ponds and indoor pools which are used all year round. The larger surface area also gives higher efficiency and reduced running costs all year round.

Thermotec Inverter Pro 9kW, 12kw, 17kw, 20kw – Single Fan, Horizontal	Thermotec Inverter Pro 24kW – Twin Fan, Horizontal

We also have the New Thermotec Inverter Pro Vertical fan 29kw single phase and 34kw single and 3 phase models. Please Click Here to see details and pricing

3. Key Benefits of the New Thermotec Inverter Pro Horizontal Range

• The Thermotec Inverter heat pumps have larger size evaporators (fins). This gives them more surface area and allows more heat to be captured from the air. This allows the unit to produce more heat at low air temperatures (down to -15c) than competitor products, making them the best choice for koi ponds and indooor pools which are used all year round.
• Colour touch screen controls – provides easy to use operation and programming of the unit. The colour display shows a graph of the running speed of the unit as well as information such as water inlet and outlet temperatures, ambient air temperature, current water temperature etc
• Programmable temperature accuracy to +/- 0.5c (or down to +/- 0.1c). This makes the Thermotec Inverter ideal for koi ponds  or where more accuracy is required over the temperature variance above and below the desired set point. No external thermostat is required.
• Electronic gas pressure sensor – allows the unit to more accurately control the compressor and fan speed resulting in higher efficiency and lower running costs
• Unique wifi platform allows remote support for the product if requried. Our technicians can check all settings and monitor performance of the heat pump remotely to provide you with the highest level of support and the fastest issue resolution.

4. What size heat pump do I require for my pool?

The sizing guide for a covered pool is:-

5. The sizing guide for koi ponds is:-

For a koi pond that is heated all year round with a winter temperature of around 12c and a summer temperature of around 20-22c, we recommend the following sizing:-

(Note: This assumes that the pond is covered in winter and that a temperature of +12c is to be maintained over winter)

For more information on using a heat pump on a koi pond, please see our Koi Pond Heating Guide page. This includes customer videos showing a Thermotec Inverter heat pump being installed and running on a koi pond

(Please note this picture shows the old colour casing)

All sizes of Thermotec Inverter heat pumps are available for standard single phase power (ie 220v to 240v) to suit most properties

For koi ponds the Thermotec Inverter range can be programmed to give a temperature control accuracy (swing) of +/- 0.5c or less without requiring a separate external thermostat.

Note: When using a heat pump to heat a koi pond, a backup heater should also be installed to provide additional heat in extremely cold weather and in the rare event that the heat pump does not function. A minimum pond water temperature of +8c is required in order for the heat pump to start.

6. 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 !

7. 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.

8. Colour Touch Screen Controls

The Thermotec Inverter have a unique 5″ colour backlit touch screen control/display panel

This provides easy to use controls

The display will show:-

• The current pool water temperature
• The mode (e.g. heating or cooling)
• If the timer function has been set
• If the fan is operating
• The current time and date
• The outside ambient temperature
• If there is a fault, a fault code is displayed to explain the problem

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

9. Wi-Fi Control

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

There are two versions of the wifi module:-

Wifi Module with 1 LED (Before Aug 2020) Uses the Inverter Temp App	Wifi Module with 4 LEDs (After Aug 2020) Uses the Aqua Temp App
