Heat Pump 5


Our heat pump 5 is another brand-new model released in April of 2022. our 5kw rated air source heat pump comes with a titanium heat exchanger, r32 eco-friendly refrigerant, auto defrost and is extremely quiet. This model is rated at only 33db. A smaller compact model this 5kw Air source heat pump is an ideal solution. 

With an operating ambient air temperature of minus 5°c to plus 43°c and able to heat your hot tub water to 40°c, this on – off air source heat pump is a far more cost-effective way to heat your hot tub. Not only is this more friendly to your wallet but is also more friendly to the environment.

Capable of heating a large volume of water up to 15,000, this air source heat pump is an excellent choice for use in a hot tub. (For swim spas we would recommend the heat pump 7 or 9)


  • Electrical requirements – The heat pump does not need any additional electrical installation on site as the unit will take its power from the hot tub. 
  • Planning – Each installation will vary, and we will undertake a site survey to review and discuss the best fitment and location for the heat pump. This survey is free of charge to our local clients and is a fantastic opportunity to discuss the best option for the installation of the heat pump.
  • Installation – The heat pump can be installed up to maximum of 10 metres from the hot tub and will need a solid level area to be placed on. Our standard pricing includes installation 500mm – 1000mm from the hot tub. Positioning of the heat pump further than this may incur additional cost for materials and labour. Pipe lagging is not included but this can be added by the customer should they require. We would advise lagging of pipes for long distances of over 3 metres.
  • Fitment – We will undertake some basic modifications to your hot tub to plumb the heat pump into the heating system. There will be an inlet and outlet pipe plumbed into the hot tub base or cabinet to provide the circulation through the heat pump. 
  • Location – The heat pump requires a minimum of 450mm of inlet space and is recommended to have minimum 1500mm of space for the fan outlet.
  • Size – The unit measures L 505 mm – W 360 mm – H 545 mm
  • Noise – Super quite at 33db.
  • Operating range – The unit will operate with an ambient air temperature from as low as minus 5°c and will heat up the water up to 40°c
  • Guarantee – 2 years on the unit’s components and 5 years on the titanium heat exchanger
