| Notes: |
• Mini 2.5kW Model: Refers to the power input of the smallest variant in this series. For precise sizing, use the formula: Pool Surface Area (m²) × 0.15~0.20 kW/m². • All data measured under standard conditions (Air 24°C / Water 26°C / Humidity 80%). Performance may vary based on local climate. • All units are 100% factory-tested (72-hour continuous run) before shipment. Test certificates are traceable per serial number. |

FAQ — Frequently Asked Questions About Pool Heat Pumps
Q: How do I choose the right size (e.g., 2.5kW vs. larger models) for my pool?
A: A general rule of thumb is 0.15 to 0.20 kW of heating capacity per square meter of pool surface area. For example, a 15m² above-ground pool typically requires a ~2.5kW input unit. For larger in-ground pools (over 50m²), please refer to our BHP series models (15–160) in the spec table above. Contact us for a free sizing calculation.
Q: How much can I save compared to gas or electric heaters?
A: With a COP of 4.0~4.5, Blueway heat pumps deliver 4 to 4.5 units of heat for every 1 unit of electricity consumed. This translates to 60%~80% lower operating costs than gas or electric resistance heaters — verified by our long-term data from Hilton Hotels projects.
Q: Why is a titanium heat exchanger important for pool applications?
A: Pool water contains chlorine, salt, and other chemicals that corrode standard copper or aluminum coils. Our PVC-shell + Titanium-tube exchanger offers 100% corrosion resistance, ensuring a leak-free lifespan of over 15 years — even in saltwater pools.
Q: Can this unit cool the pool water in summer?
A: Yes. All Blueway pool heat pumps feature a reverse-cycle (4-way valve) system. In summer, it reverses the refrigeration cycle to act as a chiller, keeping your pool water refreshingly cool (down to 22°C) during heatwaves.
Q: How long is the warranty and what does it cover?
A: We provide a 1-year warranty on the complete unit and an extended 3-year warranty on the scroll compressor. This reflects our confidence in the durability of our core components.
Q: What is the production lead time?
A: Standard production is approximately 35 working days after receipt of payment and final technical approval. Stock units may be available for urgent projects.
