Eco-Friendly R32 Refrigerant

The S21 series heat pump uses R32 refrigerant, making it an eco-friendly choice. R32 has a Global Warming Potential (GWP) of 675, far lower than the 2088 of traditional R410A. This low GWP means that R32 has a reduced impact on global warming, helping to fight climate change.


Using R32 refrigerant meets strict environmental regulations while delivering heating and cooling functions. This makes it easy to keep your pool at the perfect temperature all year round. Choose the S21 Series with R32 refrigerant to enjoy warm pool water anytime, while protecting the planet. It gives you comfort and peace of mind.

FAQ


Q1: How do I select the appropriate power level from the 7-35kW options for my pool?

A: Choosing the right size relies on your pool's volume and local weather. As a rule, 7-9kW fits small pools (20-30m³), 9-21kW handles medium ones (30-63m³), and 21-35kW covers large pools (63-105m³). Our team offers complimentary expert advice to guarantee peak performance.


Q2: Does this unit heat and cool the pool water?

A: Absolutely. Our R32 inverter pool heat pump delivers heating and cooling with smart auto-switching. It warms water between 8°C and 40°C, cools from 8°C to 28°C, and adapts to outside conditions for all-year-round swimming pleasure.


Q3: Just how much greener is R32 than older refrigerants?

A: R32 cuts greenhouse emissions by 60% versus R410A, boosts energy efficiency by 10%, and has no ozone impact. It's recyclable and easy to handle, so our heat pump is far more planet-friendly without sacrificing top-notch results.


Q4: How silent is 46dB running, and when does it kick in?

A: At 46dB, it's whisper-quiet, like a hushed library or gentle murmur. Silent mode engages once the pool hits your set temperature, slowing the compressor and fan to minimal speeds. Ideal for homes, it won’t bother neighbors or your downtime.
