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.

New for 2020, the Thermotec Eco Inverter range of pool heat pumps offer an excellent inverter driven heat pump at a low cost with high value for money.

The Thermotec Eco 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.

The ability to adjust the output of the heat pump allows the Thermotec Eco Inverter to deliver greatly reduced running costs with COPs of up to 12.5. This means that for every 1kw of electricity used by the heat pump, 12.5kw 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.

2. Features

  • Fully inverter driven with variable speed fan and compressor to deliver the lowest running costs with maximum heat output
  • High efficiency with COPs of up to 12.5. This means that for every 1kw of electricity used by the heat pump, up to 12.5kw of heat is returned to the pool.
  • Equipped with an easy to use touch screen display / control panel.
  • Top quality Mitsubishi variable speed inverter compressor
  • Brushless variable speed DC fan motor – very efficient with extremely quiet operation
  • Control panel is lockable to prevent tampering with the pool set temperature (useful for rented properties)
  • Five different models: 7kw, 9kw, 12kw, 16kw, 19kw
  • All models use single phase power (ie 220v to 240v)
  • Provides cooling and heating of pool water
  • Suitable for pools, swim spas, hot tubs and koi ponds etc
  • Soft start with reduced electrical startup requirements for properties with sensitive or limited power supplies
  • Low noise, variable speed fan.
  • Corrosion resistant case
  • Microprocessor controlled
  • Automatic hot gas defrosting.
  • Built in timer and clock
  • Set Temperatures for this model are 15-43 degrees

3a. What size heat pump do I require for my pool?

The sizing guide for a covered pool is:-

Model Kw Above Ground Pool

Max Pool Volume

In ground Pool
Max Pool Volume
In Ground
Absolute Max Pool Volume
Thermotec Eco Inverter Horizontal 7kw 18m3 25m3 35m3

Thermotec Eco Inverter Horizontal 19kw 55m3


4. COP And Performance

By using the latest inverter technology, the Thermotec Eco 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 Eco 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 -5c

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 12.5. This means that in these conditions, 1kw of electricity consumed by the heat pump will output 12.5kw of heat to your pool !

5. Extremely Quiet Operation

The Thermotec Eco 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.

6. Controls



The Thermotec Eco Inverter display will show:-

  • The current pool water temperature
  • The mode (e.g. heating or cooling)
  • Clock/time
  • 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
  • There is a protective flap over the display to protect it from the weather and UV rays from the sun
  • Inlet water temperature
  • Outlet water temperature
