How Infrared Panels and Heat Pumps Work: The Core Differences

Infrared Panels: Direct Heat, No Frills

Infrared panels work by emitting long-wave infrared radiation, which heats objects and people directly-like sunlight, but without warming the air first. They’re typically mounted on walls or ceilings and powered by electricity. Key features:

  • Instant heat: Panels reach full temperature in 5-10 minutes.
  • No moving parts: Silent operation and minimal maintenance.
  • Zonal heating: Ideal for heating specific rooms (e.g., a home office or bedroom) rather than the whole house.
  • Low water content: No risk of freezing or leaks.

However, infrared panels don’t heat the air itself, which means:

  • Rooms can feel cooler if you’re not in direct line of sight of the panel.
  • They’re less effective in poorly insulated homes, as heat is quickly lost through walls and windows.
  • They don’t provide hot water, so you’ll still need a separate system (e.g., an immersion heater or gas boiler).

Heat Pumps: Whole-Home Heating with a Catch

Heat pumps (air source or ground source) extract heat from the air, ground, or water and amplify it using a refrigerant cycle. They work like a fridge in reverse, transferring heat into your home. Key features:

  • Whole-home heating: Can replace gas boilers entirely, including hot water.
  • High efficiency: For every 1 kWh of electricity used, they produce 3-4 kWh of heat (vs 1 kWh for infrared panels).
  • Works in cold weather: Modern heat pumps operate efficiently even at -15°C (though output drops in extreme cold).

But heat pumps have key limitations:

  • Slower to heat up: They work best with low-temperature radiators or underfloor heating, which take longer to warm a room.
  • Higher upfront cost: Installation is more complex, often requiring new radiators, pipework, or insulation upgrades.
  • Outdoor space needed: Air source heat pumps require an external unit, while ground source systems need garden space for trenches or boreholes.

Key takeaway: Infrared panels are a plug-and-play solution for small spaces, while heat pumps are a long-term investment for whole-home heating-if your property is suitable.

Upfront Costs: Infrared Panels vs Heat Pumps in 2026

Infrared Panel Costs: Low Entry, Limited Scope

Infrared panels are cheaper to install but only heat individual rooms. Here’s what to expect:

ComponentCost (2026)Notes
Panel (per unit)£200-£600Prices vary by wattage (300W-1000W) and design (basic vs designer).
Thermostat (per room)£50-£150Smart thermostats (e.g., Hive, Nest) add convenience but cost more.
Installation£100-£300 per panelSimple wall/ceiling mounting; no pipework or radiators needed.
Total for 3-bed semi£1,500-£4,000Covers 4-6 panels (enough for living room, bedrooms, and home office).

No grants available: Unlike heat pumps, infrared panels don’t qualify for the Boiler Upgrade Scheme or other UK incentives. However, some local councils offer small grants for energy-efficient upgrades-check your area’s Energy Saving Trust page for details.

Heat Pump Costs: High Upfront, Long-Term Savings

Heat pumps cost significantly more upfront but can replace your entire heating system. Here’s the breakdown:

ComponentAir Source (ASHP)Ground Source (GSHP)Notes
Heat pump unit£6,000-£10,000£10,000-£18,000GSHP costs more due to groundwork (trenches/boreholes).
Installation£2,000-£5,000£5,000-£10,000Includes labour, pipework, and electrical upgrades.
Radiator upgrades£1,000-£3,000£1,000-£3,000May need low-temperature radiators or underfloor heating.
Hot water cylinder£800-£1,500£800-£1,500Required for storing hot water (not needed with infrared panels).
Total before grant£9,800-£18,000£16,800-£32,500
Boiler Upgrade Scheme-£7,500-£7,500GOV.UK Boiler Upgrade Scheme covers ASHP and GSHP.
Total after grant£2,300-£10,500£9,300-£25,000

Hidden costs to watch for:

  • Insulation upgrades: Heat pumps work best in well-insulated homes (EPC C or above). If your home is poorly insulated, you may need to budget £1,000-£5,000 for cavity wall, loft, or floor insulation.
  • Electrical upgrades: Heat pumps require a dedicated circuit and may need a new consumer unit (£500-£1,500).
  • Planning permission: Rarely needed for ASHPs, but always check with your local council-especially for listed buildings or conservation areas.

Key takeaway: Infrared panels are cheaper to install but only heat individual rooms. Heat pumps cost more upfront but can replace your entire heating system-and the £7,500 grant makes them far more affordable.

Running Costs Compared: Which Saves You More?

Infrared Panel Running Costs: Simple but Expensive

Infrared panels are 100% efficient (all electricity is converted to heat), but they don’t benefit from the high efficiency of heat pumps. Here’s how the numbers stack up for a 3-bed semi-detached home in 2026:

FactorInfrared PanelsNotes
Annual electricity use8,000-12,000 kWhBased on heating 4-6 rooms for 6-8 hours/day (October-April).
Electricity cost (OFGEM cap)28.6p/kWh (Jan-Mar 2026)OFGEM price cap for Q1 2026.
Annual running cost£2,288-£3,432£190-£286/month during heating season.
Supplemental heating£300-£800/yearMany homes need additional heating (e.g., portable heaters) in winter.

Real-world example: A homeowner in Bristol with 6 infrared panels (total 4.5 kW) reported £1,800/year in electricity costs-but only heated 3 rooms consistently. The rest of the house relied on portable heaters, adding £500/year.

Heat Pump Running Costs: Efficient but Dependent on Insulation

Heat pumps are 3-4x more efficient than infrared panels, but their running costs depend on:

  • Heat pump efficiency (SCOP): Seasonal Coefficient of Performance (SCOP) measures efficiency over a year. A SCOP of 3.5 means 3.5 kWh of heat per 1 kWh of electricity.
  • Home insulation: Poorly insulated homes lose heat faster, forcing the heat pump to work harder.
  • Hot water demand: Heat pumps also heat your water, adding 1,000-2,000 kWh/year to electricity use.

Here’s the breakdown for the same 3-bed semi:

FactorAir Source (ASHP)Ground Source (GSHP)Notes
Annual electricity use4,000-6,000 kWh3,500-5,000 kWhGSHP is slightly more efficient due to stable ground temperatures.
Electricity cost (28.6p/kWh)£1,144-£1,716£1,001-£1,430
Hot water (extra)£200-£400£200-£400
Total annual cost£1,344-£2,116£1,201-£1,830£112-£176/month during heating season.

Real-world savings: A 2023 Energy Saving Trust study found that UK homes switching from gas boilers to heat pumps saved £300-£800/year on energy bills. However, this assumes:

  • The home is well-insulated (EPC C or above).
  • The heat pump is properly sized (not oversized, which wastes energy).
  • The homeowner uses smart controls (e.g., weather compensation, zonal heating).

Key takeaway: Heat pumps save you money long-term, but only if your home is insulated and the system is designed correctly. Infrared panels are cheaper to install but more expensive to run-and they don’t replace your entire heating system.

Efficiency and Performance: What the Numbers Really Mean

Infrared Panels: 100% Efficient, But Limited

Infrared panels convert 100% of electricity into heat, but this doesn’t tell the whole story. Here’s why:

  • No heat storage: Infrared panels stop heating as soon as they’re turned off, unlike heat pumps, which can store heat in radiators or underfloor systems.
  • Direct vs indirect heating: Infrared heats objects and people, not the air. This means:
    • Faster perceived warmth (you feel warm even if the air is cool).
    • Less heat loss through draughts (since air isn’t being heated).
    • But: Rooms can feel cold if you’re not near the panel, and humidity isn’t reduced (unlike with heat pumps, which dehumidify slightly).

When infrared panels make sense:

  • Small spaces: A home office, garage, or annex where you only need occasional heat.
  • Poorly insulated homes: If your home can’t be insulated (e.g., listed buildings), infrared panels waste less heat than a heat pump.
  • Supplemental heating: Pairing infrared panels with a heat pump can reduce running costs by heating only occupied rooms.

Heat Pumps: 300-400% Efficient, But Dependent on Conditions

Heat pumps have a Seasonal Coefficient of Performance (SCOP) of 3-4, meaning they produce 3-4 kWh of heat for every 1 kWh of electricity. But this efficiency varies by temperature:

  • Above 7°C: SCOP of 3.5-4.5 (very efficient).
  • Below 0°C: SCOP drops to 2-2.5 (still better than infrared panels, but less efficient).
  • Extreme cold (-15°C): SCOP can fall to 1.5-2 (similar to electric resistance heating).

When heat pumps shine:

  • Well-insulated homes: Heat pumps work best in homes with low heat demand (e.g., EPC B or above).
  • Whole-home heating: Unlike infrared panels, heat pumps can replace gas boilers entirely, including hot water.
  • Long-term savings: Even with higher upfront costs, heat pumps pay for themselves in 7-15 years (vs 20+ years for infrared panels).

Key takeaway: Infrared panels are 100% efficient but limited in scope. Heat pumps are 3-4x more efficient but require a well-insulated home to perform at their best.

Comfort and Practicality: Which Feels Better in Your Home?

Infrared Panels: Instant Warmth, But Inconsistent

Pros:

  • No noise: Unlike heat pumps (which have a quiet outdoor unit), infrared panels are completely silent.
  • No draughts: Since they don’t heat the air, there’s no forced convection (unlike radiators or heat pumps).
  • Aesthetic options: Panels come in mirror, picture, or glass designs, blending into your decor.
  • No maintenance: No moving parts means no servicing (unlike heat pumps, which need annual checks).

Cons:

  • Spotty heat: Rooms feel warm near the panel but cold in corners or behind furniture.
  • No humidity control: Unlike heat pumps, infrared panels don’t dehumidify, which can lead to condensation in poorly ventilated homes.
  • No hot water: You’ll still need a separate system (e.g., immersion heater or gas boiler) for showers and taps.

Best for:

  • Small spaces (e.g., a home office, bathroom, or garage).
  • **Homes with limited outdoor space (no room for a heat pump unit).
  • People who want instant heat without waiting for radiators to warm up.

Heat Pumps: Whole-Home Comfort, But Slower to Heat

Pros:

  • Consistent warmth: Heat pumps maintain a steady temperature, unlike infrared panels, which create hot and cold spots.
  • Hot water included: No need for a separate boiler or immersion heater.
  • Dehumidifies: Heat pumps remove moisture from the air, reducing condensation and mould risk.
  • Works with smart controls: You can zone your heating (e.g., warmer in the living room, cooler in bedrooms).

Cons:

  • Slower to heat up: Heat pumps work best with low-temperature radiators or underfloor heating, which take longer to warm a room (30-60 minutes vs 5-10 minutes for infrared panels).
  • Noise: Air source heat pumps have an outdoor unit that hums (around 40-60 dB, similar to a fridge). Ground source heat pumps are quieter but require more space.
  • Maintenance: Heat pumps need annual servicing (£100-£200/year) to keep them running efficiently.

Best for:

  • Whole-home heating: If you want to replace your gas boiler entirely.
  • Well-insulated homes: Heat pumps perform best in homes with low heat demand.
  • Long-term savings: If you’re planning to stay in your home for 10+ years, heat pumps pay for themselves.

Key takeaway: Infrared panels offer instant, silent heat but only for individual rooms. Heat pumps provide whole-home comfort but require more planning and upfront cost.

Grants and Incentives: Maximising Your Savings

Infrared Panels: No UK-Wide Grants (Yet)

As of 2026, infrared panels don’t qualify for the Boiler Upgrade Scheme or other national heat pump grants. However, you may find local incentives:

  • Local council grants: Some councils offer £200-£500 for energy-efficient upgrades. Check the Energy Saving Trust’s grant finder.
  • VAT relief: Infrared panels are zero-rated for VAT (5% instead of 20%) if installed as part of a home energy efficiency upgrade.
  • Smart Export Guarantee (SEG): If you pair infrared panels with solar PV, you can sell excess electricity back to the grid (typically 3-5p/kWh).

Key takeaway: Infrared panels are cheaper upfront but don’t qualify for major grants. Your best bet is local council schemes or pairing them with solar PV.

Heat Pumps: £7,500 Off with the Boiler Upgrade Scheme

The Boiler Upgrade Scheme (BUS) offers £7,500 off the cost of an air source or ground source heat pump (until 2028). Here’s how to qualify:

  • Property eligibility: Must be in England or Wales (Scotland has separate schemes).
  • Installer requirements: Must be MCS-certified (find an installer here).
  • No new-builds: Only existing homes qualify (not self-builds or new developments).
  • No hybrid systems: The heat pump must be the primary heating source (not paired with a gas boiler).

Other heat pump incentives:

  • 0% VAT: Heat pumps are zero-rated for VAT (5% instead of 20%) until 2027.
  • Renewable Heat Incentive (RHI): Closed to new applicants in 2022, but existing RHI payments continue until 2028.
  • Local grants: Some councils offer additional funding (e.g., £500-£1,000 for insulation upgrades).

Key takeaway: Heat pumps are expensive upfront, but the £7,500 grant makes them far more affordable. Always use an MCS-certified installer to qualify.

Environmental Impact: Which is Greener?

Infrared Panels: Low Carbon, But Dependent on Grid Electricity

Infrared panels are 100% electric, so their carbon footprint depends on the UK grid’s electricity mix:

  • 2026 grid carbon intensity: ~100 gCO₂/kWh (down from ~180 gCO₂/kWh in 2023, thanks to more renewables).
  • Annual emissions for a 3-bed semi: 800-1,200 kgCO₂/year (based on 8,000-12,000 kWh/year).
  • Comparison to gas boiler: A gas boiler emits ~2,400 kgCO₂/year for the same home, so infrared panels are ~50-67% lower carbon.

But:

  • If your electricity comes from renewables (e.g., solar PV), infrared panels can be near-zero carbon.
  • If the grid reverts to fossil fuels (e.g., during a cold snap), emissions rise temporarily.

Heat Pumps: The Lowest-Carbon Heating Option

Heat pumps are 3-4x more efficient than infrared panels, so they use less electricity-and thus have a lower carbon footprint:

  • 2026 grid carbon intensity: ~100 gCO₂/kWh.
  • Annual emissions for a 3-bed semi: 400-600 kgCO₂/year (based on 4,000-6,000 kWh/year).
  • Comparison to gas boiler: ~80% lower carbon than a gas boiler.

Additional benefits:

  • No local emissions: Unlike gas boilers, heat pumps don’t produce NOx or CO (which contribute to air pollution).
  • Future-proof: As the grid decarbonises, heat pumps will become even greener.

Key takeaway: Both systems are lower carbon than gas boilers, but heat pumps are the greenest option-especially if your home is well-insulated.

Illustrative Composite: The Thompsons’ 3-Bed Semi in Manchester

Illustrative composite based on typical UK installations.

The Thompsons live in a 1930s semi-detached home in Manchester (EPC D, 90 m²). They currently use a 20-year-old gas boiler (£1,500/year in gas bills) and want to switch to a low-carbon heating system. Here’s how the numbers stack up:

Option 1: Infrared Panels

  • Panels installed: 6 panels (total 4.8 kW) covering the living room, kitchen, and 3 bedrooms.
  • Upfront cost: £3,200 (no grant).
  • Annual running cost: £2,000 (electricity) + £500 (supplemental heating) = £2,500/year.
  • Carbon emissions: 1,000 kgCO₂/year (vs 2,400 kgCO₂/year for gas).
  • Comfort: Warm in occupied rooms, but cold in hallways and bathrooms.

Option 2: Air Source Heat Pump

  • Heat pump installed: 8 kW ASHP with new low-temperature radiators and hot water cylinder.
  • Upfront cost: £12,000 (before grant) → £4,500 after £7,500 BUS grant.
  • Annual running cost: £1,200 (electricity) + £200 (hot water) = £1,400/year.
  • Carbon emissions: 500 kgCO₂/year (80% lower than gas).
  • Comfort: Whole-home warmth, but slower to heat up than infrared panels.

The Decision

The Thompsons chose the heat pump because:

  1. Long-term savings: They’ll save £1,100/year on energy bills (vs £1,000/year with infrared panels).
  2. Whole-home heating: No need for supplemental heaters in winter.
  3. Future-proofing: They plan to stay in the home for 10+ years, so the higher upfront cost pays off.
  4. Grants: The £7,500 grant made the heat pump cheaper than expected.

But: They had to upgrade their insulation (£1,500 for cavity wall and loft insulation) to get the best performance from the heat pump.

FAQ

1. Can I use infrared panels and a heat pump together?

Yes! This is a growing trend in the UK, especially for homes with poor insulation or large, rarely used spaces (e.g., a guest bedroom). Here’s how it works:

  • Heat pump: Handles whole-home heating and hot water.
  • Infrared panels: Provide supplemental heat in specific rooms (e.g., a home office or bathroom).
  • Benefits:
    • Lower running costs: You can turn down the heat pump and use infrared panels in occupied rooms only.
    • Faster warmth: Infrared panels heat up instantly, while heat pumps take 30-60 minutes.
  • Cost: Adding 2-3 infrared panels to a heat pump system costs £1,000-£2,000 but can reduce running costs by 10-20%.

Best for: Homes where one or two rooms need extra heat (e.g., a conservatory or loft conversion).

2. Do infrared panels work in poorly insulated homes?

Infrared panels can work in poorly insulated homes, but they’re not ideal. Here’s why:

  • Heat loss: Infrared panels heat objects and people, not the air. In a draughty home, heat is quickly lost through walls, windows, and floors.
  • Supplemental heating: You’ll likely need additional heaters (e.g., portable radiators) in winter, increasing running costs.
  • Cold spots: Rooms will feel warm near the panel but cold in corners or behind furniture.

Alternatives for poorly insulated homes:

  • Heat pump + insulation: If you upgrade insulation first, a heat pump can heat your home efficiently.
  • Hybrid system: Pair a heat pump with a gas boiler (though this doesn’t qualify for grants).
  • Infrared panels + dehumidifier: If you must use infrared panels, a dehumidifier can help reduce condensation.

Key takeaway: Infrared panels are better than electric heaters in poorly insulated homes, but not as efficient as a heat pump + insulation.

3. How long do heat pumps and infrared panels last?

SystemLifespanWarrantyMaintenance
Infrared panels20-30 years5-10 yearsNone (no moving parts).
Air source heat pump15-20 years5-7 years (parts)Annual service (£100-£200/year).
Ground source heat pump20-25 years5-10 years (parts)Annual service (£150-£300/year).

Infrared panels:

  • No moving parts means no wear and tear.
  • Lifespan depends on build quality: Cheap panels may fade or crack after 10-15 years.
  • Warranty: Typically 5 years (but some brands offer 10 years).

Heat pumps:

  • Outdoor unit: Lasts 15-20 years (similar to a gas boiler).
  • Indoor unit: Lasts 20+ years (but may need refrigerant top-ups).
  • Maintenance: Annual servicing is essential to maintain efficiency (neglecting this can reduce lifespan by 5-10 years).

Key takeaway: Infrared panels last longer and require no maintenance, while heat pumps need annual servicing but provide whole-home heating.

4. Are heat pumps noisy?

Heat pumps do make noise, but modern units are much quieter than older models. Here’s what to expect:

  • Air source heat pumps (ASHP):
    • Outdoor unit: 40-60 dB (similar to a fridge or quiet conversation).
    • Indoor unit: 20-30 dB (barely noticeable).
    • Noise regulations: UK planning rules limit outdoor unit noise to 42 dB at 1 metre (check with your installer).
  • Ground source heat pumps (GSHP):
    • Much quieter: No outdoor unit (just a small pump inside).
    • Noise level: 30-40 dB (similar to a quiet library).

Tips to reduce noise:

  • Place the outdoor unit away from bedrooms (e.g., on a side wall or garden shed).
  • **Use a soundproof base (e.g., a rubber mat or concrete slab).
  • Check the dB rating before buying (aim for <50 dB).

Key takeaway: Heat pumps are not silent, but they’re quieter than a gas boiler’s flue. If noise is a concern, ground source heat pumps are the best option.

5. Can I install a heat pump myself to save money?

No. Heat pumps must be installed by an MCS-certified installer to qualify for:

  • The £7,500 Boiler Upgrade Scheme grant.
  • Warranty coverage (most manufacturers void warranties for DIY installations).
  • Building regulations compliance (heat pumps require electrical and plumbing work that must be signed off by a professional).

Why DIY is a bad idea:

  • Refrigerant handling: Heat pumps use fluorinated gases (F-gases), which require a certified technician to handle.
  • Electrical work: Heat pumps need a dedicated circuit and may require a new consumer unit (£500-£1,500).
  • System design: A poorly sized heat pump (too big or too small) will waste energy and reduce lifespan.

How to save money on installation:

  • Get multiple quotes (use our installer finder).
  • Upgrade insulation first (reduces the size of heat pump you need).
  • **Choose a low-temperature system (cheaper to install than underfloor heating).

Key takeaway: Never install a heat pump yourself. Use an MCS-certified installer to qualify for grants and ensure efficiency.
