🏊 Pool Sizing & Heating Guide

Is This Heat Pump Right for Your Pool?

Recommended Pool Volume: 70–85 m³ (cubic meters)

How to Calculate Your Pool Volume:

Rectangular Pools:
Volume (m³) = Length (m) × Width (m) × Average Depth (m)

Circular Pools:
Volume (m³) = π × Radius² (m) × Average Depth (m)
Radius = Diameter ÷ 2

Oval Pools:
Volume (m³) = π × Length (m) × Width (m) × Average Depth (m) ÷ 4

Example Pool Sizes (70-85m³):

• 10m × 5m × 1.5m (avg depth) = 75 m³ ✅
• 12m × 5m × 1.3m (avg depth) = 78 m³ ✅
• 8m × 6m × 1.4m (avg depth) = 67 m³ (slightly small, but acceptable)
• Circular pool 10m diameter × 1.1m (avg depth) = 86 m³ (slightly large, but acceptable)

Important: Always use a pool cover when not swimming to reduce heat loss by up to 75%!

⏱ Estimated Heat-Up Times

These estimates are calculated using standard formulas and the heat pump’s rated capacity. Actual times may vary based on ambient temperature, wind conditions, pool insulation, and whether a pool cover is used.

Heat-Up Time Formula:
