    Pool Heater Sizing Guide: *

    Spa Heater Sizing Guide **

    5° Per Hour (Max) 10° Per Hour (Max) 20° Per Hour (Max)
    1000l 6kW 12kW 24kW
    1,500l 9kW 18kW 36kW

    * These values are calculated using the average temperature, humidity and wind speed in the location listed. The above table lists sizes for an extended season with a swimming temperature of 28 degrees Celsius.

    Calculations are based on average pool dimensions for an in-ground pool using a cover with a run time of 10 hours a day with an average wind exposure and standard shading.

    ** Spa temperature rises are based on an insulated spa with thermal hard cover & ideal conditions. Temperature rises are a maximum theoretical temperature rise for water and based on the maximum output of a heat pump.

    Where possible we recommend going at least one size above to avoid dissapointment. These tables are a guide to be used as a guide only and we take no responsiblity for innaccurate sizing, as there are too many variable to account for all scenarios.


    • Wifi APP control
    • COP up to 11 - (Air 27℃/Water 27℃/Humidity 80%) The Sensa-Heat ES will adjust the heating capacity according to the pool temperature. When running at 20%-25% speed, it reaches the highest COP11. With low-speed running philosophy, Sensa-Heat ES is more energy saving than a On/Off heat pump. 
    • R32/R410A gas - R32 is a new gen refrigerant for pool and spa heat pumps. Sensa-heat uses this in all models making for a more efficient heat pump with a lower environmental impact.
    • EEV technology - 10 times flexibility to adjust the gas flow and increase COP by up to 20%.
    • Twisted titanium heat exchanger - 40% higher efficiency than normal titanium heat exchanger.
    • Soft starting - Soft start technology smoothes out the start up power demend. And can reduce start up power demand by up to 70%
    • Hot gas defrosting - Saginomiya 4-way valve for quick & efficient deforesting.
    • Stable DC Inverter
    • Anti-rust ABS casing
    • Designed for 0℃ operation
