Q: What is a CO₂ heat pump?
A：It uses CO₂ (R744) as refrigerant. Unlike normal heat pumps, it heats water up to 90°C and works well even at -25°C outdoor temps.
Q: Why is the price higher than gas boilers or standard heat pumps?
A：It uses CO₂ (R744) as refrigerant. Unlike normal heat pumps, it heats water up to 90°C and works well even at -25°C outdoor temps.
Q: Why CO₂ instead of R32/R410A?
A:CO₂ has GWP = 1 (vs. 2,000+ for others), is non‑toxic, non‑flammable, and meets strict EU/global environmental regulations.
Q: What’s the efficiency (COP)?
A：Typically COP 3.0–4.5. Best performance with low return water temps (e.g., 30°C return / 65°C supply).
Q: Where is it mostly used?
A：Hotels, hospitals, gyms, food processing, district heating – anywhere needing high‑temp sanitary hot water.
Q: Does it work in cold climates?
A：Yes. Full capacity down to -25°C –ideal for Northern Europe, Canada, and other cold regions.
Q: Is installation different from normal heat pumps?
A：Yes – it uses higher pressure (over 10 MPa), so pipes and components are heavier. Also, system design should use wide delta T (e.g., 30–40K) for best efficiency.
Q: Why is the price higher than gas boilers or standard heat pumps?
A:Higher‑grade compressor, stronger components, and advanced controls. But operating cost is ~70–80% lower than gas/electric systems – ROI is usually within 2–4 years.
Q: How much carbon can I save?
A;Up to 78% less CO₂ emissions vs. a gas boiler – helps with BREEAM, LEED, and green building credits.
Q: What’s the lifespan?
A:15+ years with proper maintenance – longer than most gas boilers.
Q: What are your delivery times and shipping methods?
A: For in-stock items, delivery takes 1–5 working days; for out-of-stock, 15–25 days depending on quantity. Shipping options:sea(30–50 days), air (5–10 days), rail (35–45 days), or express (5–7 days). We’ll choose the best method based on your order.
