Thermotec Neo Inverter Heat Pumps with Wi-Fi for Swimming Pools 5kw to 24kw Extended Season Use

The Thermotec Neo Inverter range of pool heat pumps offer an excellent inverter driven heat pump at a low cost with high value for money. 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 Thermotec swimming pool heat pumps.
The Thermotec Neo 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 pool. 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.
The ability to adjust the output of the pool heat pump allows the Thermotec Neo Inverter to deliver greatly reduced running costs with COPs of up to 10. This means that for every 1kw of electricity used by the heat pump, 10kw of heat is delivered to the pool. This delivers reduced running costs compared with other heat pumps on the market. 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).
In addition the inverter technology has a reduced electrical startup requirement, making them ideal for properties with a sensitive or limited electrical supply. The Thermotec Neo 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 Neo Inverter will still perform well, delivering heat to your pool.
The Thermotec Neo Inverter heat pumps can work well with outside air temperatures as low as -7c
For koi ponds, we recommend using the Thermotec Inverter Pro models due to higher heat output in cold weather, however the Thermotec Neo range can be used for koi ponds if used in conjunction with an electric backup heater. The electric heater can provide additional heat in very cold weather.
The Thermotec Neo Inverter range work very silently thanks to a unique internal ventilation system and the inverter technology.

The wifi module:
Is included FREE OF CHARGE with the Thermotec Neo models

Once this module is connected, it allows control and monitoring of the heat pump using the Aqua Temp app
it also allows us to provide remote support if required

The Neo Inverter 5kw, 7kw, 9kw and 12kw can be run from a standard 13A UK Plug, larger models need to be hardwired as they can exceed 13A. The 5kw, 7kw, 9kw and 12kw come with a free 3m plug and play cable kit. This is a heavy duty piece of round flex cable with a 13A UK plug on the end.

For above ground pools, you can also use one of our pre-made Connection Kits. These allow the Intex type hoses with grey nuts to be connected to the heat pump.
Please call us if you are unsure which fittings you need.
The sizing guide for a covered pool is:-
| Model | Kw | Above Ground Pool
Max Pool Volume |
In ground PoolMax Pool Volume | In GroundAbsolute Max Pool Volume |
|---|---|---|---|---|
| Thermotec Neo Inverter Horizontal | 5.4kw | 13m3 | 20m3 | 28m3 |
| Thermotec Neo Inverter Horizontal | 7kw | 18m3 | 25m3 | 35m3 |
| Thermotec Neo Inverter Horizontal | 9kw | 25m3 | 30m3 | 50m3 |
| Thermotec Neo Inverter Horizontal | 11.5kw | 35m3 | 40m3 | 60m3 |
| Thermotec Neo Inverter Horizontal | 13.2kw | 40m3 | 45m3 | 65m3 |
| Thermotec Neo Inverter Horizontal | 15.5kw | 45m3 | 50m3 | 75m3 |
| Thermotec Neo Inverter Horizontal | 18.4kw | 55m3 | 70m3 | 95m3 |
| Thermotec Neo Inverter Horizontal | 24kw | 70m3 | 85m3 | 110m3 |
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:-
| Model | Max Pond Volume |
|---|---|
| Thermotec Neo Inverter 5.4kw | 2200 gallons |
| Thermotec Neo Inverter 7kw | 2600 gallons |
| Thermotec Neo Inverter 9kw | 2800 gallons |
| Thermotec Neo Inverter 11.5kw | 3400 gallons |
(Note: This assumes that the pond is covered in winter and that a temperature of +12c is to be maintained over winter)
Note: If the Thermotec Neo heat pumps are used on a koi pond over winter then an electric backup heater should be installed to provide additional heat in cold weather
For koi ponds, we recommend using the Thermotec Inverter Pro models due to higher heat output in cold weather, however the Thermotec Neo range can be used for koi ponds if used in conjunction with an electric backup heater. The electric heater can provide additional heat in very cold weather.
For more information on using a heat pump on a koi pond, please see our Koi Pond Heating Guide page.
All pools and ponds should be covered to prevent heat loss and save on running costs by preserving the heat in the water.
Pools should be covered with either a solar cover (outside) or a Thermal Blanket (indoor pools) for approx 20 hours a day to maximise the savings from energy wasted by heat loss from the surface of the pool water.
For outside pools the solar covers absorb energy which is passed to the pool through conduction, while the transmission properties of the bubble layer allows for Infrared Radiation (IR) wavelengths to pass through the material and be directly absorbed by the water. The material provides a barrier to evaporation, giving the pool the ability to preserve water and reduce heat loss through evaporative cooling. Prevention of evaporative losses has the largest impact on maintaining a pool’s temperature, responsible for 70% of the heat loss from the pool. EnergyGuard Selective Transmission has been tested to prevent over 98% of evaporative losses.
