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 2018, 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 pool.

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.

3b. 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:-

 Pond Sizing Guide
Model
Max Pond Volume
Thermotec Inverter Horizontal 9kw 4500 gallons
Thermotec Inverter Horizontal 12kw 6000 gallons
Thermotec Inverter Horizontal 17kw
7500 gallons
Thermotec Inverter Horizontal 19.5kw

Thermotec Inverter Vertical 29kw
13,800 gallons
Thermotec Inverter Vertical 34kw
19,900 gallons
Thermotec Inverter Vertical 34kw (3 Phase) 19,900 gallons

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

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

4. COP And Performance

By using the latest inverter technology, the Thermotec Inverter canout 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 !

5. 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.

6. Colour Touch Screen Controls

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

This provides easy to use controls

Themotec Inverter Heat Pumps Colour display

The display will show:-

  • The current pool water temperature
  • The mode (eg 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

 The Thermotec Inverter Mobile Phone App  

 

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. 

If you do not have a wifi signal at the heat pump's location, then you can either:-

  1. Use a wifi signal extender to boost the signal in the area of the heat pump
  2. Use power lan adaptors plugged into mains sockets in the house and the pool shed. You can then connect a wifi extended to the powerlan adaptor in your pool shed. 

Please Contact Us if you need assistance with the wifi configuration

Please also see the user manual for the Wi-Fi module below for more information and installation instructions

19. Customer Feedback

David, I have sent the pictures of my installation under separate email. The pump is working well and I will run it for 36 hours to test the effectiveness but so far I am very impressed with the quietness of the unit. I have to be within 5-6 metres to hear it running!
I would also like to say how impressed I have been with your service and support. You have been most helpful and always available when needed. My thanks to the other staff in your office who have always been most knowledgeable.
I will let you know the final result when the unit gets the pool up to temperature.
Thanks again
Stephen Nobbs
