R290 vs R32 Heat Pumps: Which Low-GWP Refrigerant Offers the Best Efficiency?

Introduction

Picking a heat pump isn’t like choosing a toaster. It’s an investment. And your choice of refrigerant can make or break long-term savings, carbon footprint, even safety. In our heat pump refrigerants comparison, we zero in on R290 and R32. Both are low-GWP, both comply with EU F-gas regulations, yet they play very different cards. Ready to find out which one wins in your home?

Why Refrigerant Choice Matters

Think of refrigerant as the lifeblood of your heat pump. Get it wrong, and:

• Your energy bills spike.
• Maintenance calls stack up.
• You risk non-compliance fines.
• Your carbon footprint balloons.

A robust heat pump refrigerants comparison empowers you to weigh:

• Efficiency (SCOP/COP figures).
• Environmental impact (GWP/ODP ratings).
• Safety protocols (flammability classifications).
• Running costs (energy consumption over seasons).

It’s a four-cornered ring where every factor matters. Skip one, and your champion falters.

What is R290?

R290 is simply propane. Yes, the same stuff you might use in BBQs—but ultra-purified for HVAC:

• GWP: ~3 (near-zero).
• ODP: 0.
• Latent heat of vapourisation: High (more heat absorbed per cycle).
• Safety: A2 (flammable).

Why it’s great: Excellent cold-climate performance. At –15 °C outside, it still packs enough punch to keep you cosy.
Why it’s tricky: Strict safety measures. Installers need gas detectors, venting plans, burner-proof components.

What is R32?

R32 goes by difluoromethane. A mild HFC with perks:

• GWP: ~675.
• ODP: 0.
• Volumetric cooling capacity: Approx. 87% better than R290.
• Safety: A2L (mildly flammable, lower risk).

Why it’s great: Smaller compressors, quieter operation, simpler install.
Why it’s tricky: Higher GWP than R290—so any leak hits the atmosphere harder.

Head-to-Head: R290 vs R32

In our heat pump refrigerants comparison, we slice through specs and jargon. Here’s what matters most:

1. Efficiency
   – R290: SCOP up to 5.66 at 35 °C. Stellar on frosty mornings.
   – R32: SCOP around 4.7 at 35 °C. Better for stable, milder climates.

2. Climate Performance
   – R290: King of the north.
   – R32: Prefers the south but holds its own up to 0 °C.

3. Safety & Installation
   – R290: Extra hurdles—sensor kits, ventilation, training.
   – R32: Fewer hoops, can slash installation time by 10–15%.

4. Running Costs
   – R290: Higher energy draw at moderate temps. But wins in deep cold.
   – R32: Lower bills year-round in mild zones.

5. Noise Levels
   – R290 units: Can hum louder under load.
   – R32 units: Smooth, whisper-quiet starts from 42 dB.

6. Environmental Impact
   – R290: Virtually climate-neutral leaks.
   – R32: Big leap from R410A but still a GWP 675.

7. Availability & Cost
   – R290: Premium price tag. Fewer suppliers.
   – R32: Broad supply chain. Competitive pricing.

Every point in our heat pump refrigerants comparison forces a trade-off. No magic bullet here.

NEWNTIDE vs. The Heat Pumps UK

You’ve probably seen NEWNTIDE’s R290 models marketed for their cold-climate prowess. They boast amazing SCOP numbers. But look closer:

• Installation leaps: You face extra permitting and specialist labour.
• Financing: Limited to standard loans, no green tariffs.
• After-sales: You might wait days for a service engineer.

At The Heat Pumps UK, we do things differently:

• Certified installation teams handle A2 flammability protocols.
• Flexible finance options: zero-deposit plans, green loans.
• Government grants support: we fill in your ECO4 applications.
• 24/7 support line and annual maintenance bundles.

So while NEWNTIDE dances around regulations, we lead the floor—no stumbles, no hidden costs. That’s real value when doing a heat pump refrigerants comparison.

Cost, Grants, and ROI

The headline price grabs you. But the true cost? It’s a story of grants, operation, and payback:

• Base unit + install: £6,000–£10,000.
• ECO4 grant: up to 50% off in certain regions.
• Running costs: £400–£600/year with R290 in cold zones; £300–£450 with R32 in milder zones.
• Payback: 4–7 years, depending on your energy prices.

We guide you through:

• ECO4 and local authority schemes.
• Renewable Heat Incentive (legacy claims).
• Landlord Energy Saving Allowance.

Our free home audit lays out the numbers in black and white—no guesswork.

Making the Right Choice

When wrapping up your heat pump refrigerants comparison, ask yourself:

• What’s my typical winter low?
• Do I need quiet operation near bedrooms?
• Is upfront capital a barrier?
• How quickly can I tap grants?
• Will I stay in the property long enough for full ROI?

If polar chills are your norm—lean R290.
If mild winters and swift installs appeal—opt R32.

Either way, with The Heat Pumps UK, you get:

• Tailored system design.
• Specialist installation.
• Flexible finance.
• Ongoing maintenance.

No jargon. No surprises.
