Tools

The numbers a tech needs poolside — no login, fast on a phone. Outputs are indicative; read the note under each tool.

Pool volume

Litres from shape and dimensions — the number every dose starts from.

Volume

Freeform pools use a 0.89 shape factor. Round up when dosing sanitiser down.

Salinity

Salt to add to reach chlorinator operating range.

Salt to add

Check the chlorinator's rated range — targets vary by model. 1 ppm = 1 mg/L.

Saturation index (LSI)

Is the water balanced, corrosive or scale-forming?

Index

Carbonate alkalinity = TA − CYA/3. Balanced band ±0.3.

Heat pump sizing

Which Sensaheat suits this pool, how long it takes to bring up, and what it costs to run.

A full month-by-month heat balance for WA conditions — Perth, the South West, Mid West, Great Southern, Goldfields and Pilbara. Set the pool, the blanket and the run time, and it names the unit.

  • Recommended Sensaheat model across the TDX, PiX and ES series
  • Heat-up time and running cost, month by month
  • What a blanket is worth on that pool, in dollars and in kW

Energy saving

Annual running-cost difference when swapping the pump.

Saving per year

Assumes the same run hours year-round. Variable-speed pumps often allow longer, slower runs — savings shown are conservative.
