Many heat pump suppliers use outdated sizing formulas, leading to under powered units that struggle to maintain temperature. If your customers are frustrated, it’s because their heat pump wasn’t sized correctly from the start.
❌ Common Industry Sizing Mistake:
Most brands use the formula: Pool Litres ÷ 1,800 = kW Required
👉 This method doesn’t account for seasonal temperature changes or heat loss.
✅ How CHR Heat Pumps Gets It Right:
🔹 We factor in climate, pool usage, and heat retention.
🔹 Our AstroMax models have higher COP ratings (up to 20), ensuring faster heat-up times and energy efficiency.
🔹 We guide builders on choosing the correct model to minimise running costs and customer complaints.
💡 Bigger is Better: A larger, correctly sized heat pump runs fewer hours per day, heats more efficiently, and lasts longer.
