* 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.
