Solar Pump Sizing Calculator for PoolMasterPro™ Systems

This calculator will help you size up a conventional mains solar pump for your independent or booster/retro PoolMasterPro™ solar pool heater.

For our OKU Performance+™ panel systems please use the pump sizing calculator here.

† Note: this calculator sizes pumps for independent (or booster) systems only, manual systems don't have a choice on pump power as they are run using the main filter pump which is sized to the pool's volume.
* Doubling your manifolds can halve your strip run and significantly reduce the pressure drop across the collector array. Such systems have no strip loops - instead they have manifolds at each end of the collector array.
** Include all pipe runs from the pool and to the roof and back again.
§ If electrical energy usage is your priority, choose a low flow rate, the collector efficiency loss can be compensated for with a larger collector.
‡ Daily pool water turnovers less than 50% will require you to run your filter pump in the afternoon to help mix the warm water deeper into your pool. Turnover rates and flow rates greater than 200% and 5 L/min/m² for full length 25m tube runs are not only a waste of electricity but may over-pressurise tubes. Double manifold systems (with 12.5m tube runs) on the other hand can easily run at such volume turnover rates using a lower power pump without over-pressurising the tubes.
