Infrared Heating vs Air Source Heat Pumps
Infrared heating and air source heat pumps are two very different approaches to heating buildings. Each system delivers heat in a distinct way and suits different building types, usage patterns, and installation scenarios.
This guide compares infrared heating with air source heat pumps in real UK conditions, helping you decide which option may be more appropriate for your property.
How the systems differ
Infrared heating
Infrared heating uses radiant energy to warm people and surfaces directly rather than heating the air. Panels are typically wall or ceiling mounted and provide warmth you feel quickly, without air movement.
Air source heat pumps
Air source heat pumps extract heat from outside air and transfer it into a building using a refrigeration cycle. Heat is distributed through water-based systems such as radiators or underfloor heating.
Performance and efficiency
Air source heat pumps can achieve high seasonal efficiency when designed correctly and run continuously in well-insulated properties. Performance depends heavily on system design, insulation levels, and operating temperatures.
Infrared heating performance is unaffected by outdoor air temperature. Because it heats people and surfaces directly, it can be particularly effective in rooms used intermittently or where zoned control is required.
Quick comparison
| Criteria | Infrared heating | Air source heat pump |
|---|---|---|
| Best suited for | Zoned, intermittent or single-room heating | Whole-home, continuous heating |
| Heat delivery | Radiant heat to people and surfaces | Warm air via water-based emitters |
| Installation | Low disruption, no pipework | Outdoor unit, pipework, system design |
| Maintenance | Minimal | Periodic servicing recommended |
Real-world usage scenarios
Intermittent or zoned heating
Spaces such as bathrooms, extensions, studios, workshops, and heritage buildings often benefit from infrared heating because warmth is delivered instantly to occupied areas only.
Whole-home continuous heating
Well-insulated homes that require steady, all-day heating may be better suited to air source heat pumps, where high seasonal efficiency can be achieved.
Installation and disruption
Air source heat pump installations typically involve outdoor units, pipework, and upgraded emitters, making them more suitable for new builds or major renovations.
Infrared heating systems can be installed with minimal disruption and are often chosen for retrofits, extensions, and buildings where invasive works are not practical.
Running costs
Running costs depend on how each system is used. Heat pumps can reduce electricity use per unit of heat when run continuously, while infrared heating can lower overall energy consumption by limiting heating to occupied rooms.

Which system should you choose?
Air source heat pumps may suit properties with high insulation levels and a requirement for constant, whole-home heating.
Infrared heating may be more appropriate where zoned control, faster warm-up times, and minimal installation disruption are priorities.
FAQs
Is an air source heat pump always cheaper to run?
Not always. For intermittent or zoned use, infrared heating can reduce total run-hours. For steady, whole-home heating in well-insulated properties, heat pumps are often more efficient.
Do infrared panels work with solar PV?
Yes. Infrared systems respond instantly and are well suited to using self-generated electricity in specific rooms or zones.
