Q: Is the titanium heat exchanger worth it?

A: Absolutely! Titanium is highly resistant to:

• Salt water corrosion (essential for saltwater pools)
• Chlorine and pool chemicals
• Mineral deposits and scale buildup
• Temperature stress and thermal cycling

This translates to longer lifespan, consistent performance, and lower maintenance costs compared to copper or stainless steel exchangers.

Technical & Compatibility

Q: What size pool pump do I need?

A: Your pool pump should provide the nominal flow rate of 5.0 m³/h (5,000 litres/hour) through the heat pump. Most standard pool pumps easily exceed this. Ensure proper sizing for your complete pool circulation system, not just the heat pump.

Q: Can I use this with a saltwater pool system?

A: Yes! The titanium heat exchanger is specifically designed to resist corrosion from saltwater chlorination systems. The Vertigo Fi 125 is fully compatible with salt pools and features the industry’s best corrosion protection.

Q: What’s the R32 refrigerant and is it safe?

A: R32 is a modern, eco-friendly refrigerant with significantly lower Global Warming Potential (GWP) than older refrigerants like R410A. It’s:

• More efficient (better heat transfer)
• More environmentally friendly (68% lower GWP)
