🏆 R290 vs R32 vs R410A: Heat Pump Refrigerant Comparison Guide 2026
Answer: R290 (propane) is the best refrigerant choice for heat pumps in 2026 — it has the lowest GWP (3), the highest efficiency (SCOP 4.8), and is fully compliant with 2027 EU F-Gas regulations. R32 is a transitional option with GWP 675 (acceptable until 2028-2030 in most markets), while R410A is being phased out globally with GWP 2,088.
Based on our experience supplying 15,000+ heat pump units to European installers since 2025, and ongoing lab tests conducted at our R&D facility in China. Last updated: May 2026.

🔬 Deep Dive: Refrigerant Properties
🎯 Answer: Choose R290 if you want the lowest lifetime cost and future-proof EU compliance. Choose R32 if you need a lower upfront cost and accept future regulatory risks. Avoid R410A for new installations.
🌿 R290 (Propane) — The Future Standard
- GWP: 3 — lowest of any common HFC refrigerant, 696x lower than R410A
- Efficiency: 8-12% higher SCOP than R32 in our lab tests
- Compliance: Not affected by EU F-Gas quota phase-down
- Our experience: Since launching R290 units in early 2026, we've seen a 73% adoption rate among European installer partners switching from R32
⚡ R32 — The Transitional Choice
- GWP: 675 — 68% lower than R410A but still significant
- EU status: Pre-charged R32 imports face quota restrictions from 2027
- Best use case: Budget-constrained projects where installer is not concerned about 2030 compliance
🛑 R410A — The Retiring Standard
- GWP: 2,088 — highest of the three, subject to carbon taxation in EU
- EU status: Service-only from 2027 for most applications
- Our recommendation: We advise against new R410A installations. Existing R410A units should plan replacement by 2028

❓ Frequently Asked Questions
❓ Can I use R290 in a split heat pump system?
Answer: Yes, but only with outdoor installation of the R290 condensing unit. Most European building codes restrict indoor R290 installations to charge sizes under 150g. For monobloc systems, the entire R290 charge is outside, making them the simplest choice for residential retrofit.
❓ How long will R32 heat pumps remain serviceable?
Answer: R32 will remain available for servicing through approximately 2035. However, the price of R32 refrigerant is projected to rise 300-500% by 2030 due to the HFC quota reduction. New installations in 2026-2027 will have a 8-10 year service window before refrigerant costs become prohibitive.
❓ Does Kuding offer R290 heat pumps with DDP delivery to Europe?
Answer: Yes. All Kuding R290 units are available with MOQ 1 and DDP door-to-door delivery to any European address, including customs clearance and all import taxes. We ship from our China stock within 5-7 business days. Sea freight DDP takes 30-40 days to European ports.
