MATHEMATICAL METHOD
You can determine your heater power and also weather elevation rate for a given
heater by applying this formula:
•
How to establish the heater power:
Power (KW) = K (W/°Cft²) X temp.diff. (°C) X surfpool. (pi²)
1000 (W/KW)
K: Conversion constant: 5.715 W/°ft²
Temp. Diff.: Temperature spread between water surface and
ambient air. Normal use is generally between
5°C and 8°C.
K:
•
How to determine temperature elevation rate:
Elevation (°C/hour) = K (°Cft³/KWH) X Power (KW)
Surf.pool (ft²) X av.depth (ft)
