Infrared Heating vs Air Source Heat Pumps: How Do They Work?

Infrared Heating

Infrared heating panels produce heat by emitting infrared radiation that directly warms objects and people in their path, much like the warmth felt from the sun. 

This makes infrared panels efficient for localized heating and instant warmth but less effective at heating large spaces evenly. Below are the pros and cons of infrared heating:

Pros
  • Quick, direct heat with no warm-up time.
  • Simple installation and low upfront costs.
  • Minimal maintenance required.
  • Ideal for supplementary or spot heating.
  • Silent operation with no moving parts.
Cons
  • Higher running costs due to electricity usage.
  • Inefficient for heating large or poorly insulated spaces.
  • Does not provide whole-home heating solution.
  • Limited to specific room heating; no integration with existing systems.

Air Source Heat Pumps

In contrast, air source heat pumps extract heat from the outside air even at low temperatures and amplify it to warm the indoor environment through radiators, underfloor heating, or warm air systems. 

They operate on electricity but deliver significantly more heat energy than the electricity they consume, making them highly efficient for whole-property heating. To learn more about how these systems actually function, read our detailed explanation of how heat pumps work. Below, we’ll briefly discuss the pros and cons of air source heat pumps.

Pros
  • Highly energy efficient with low running costs.
  • Suitable for whole-house heating and hot water.
  • Reduces carbon emissions significantly.
  • Compatible with renewable energy systems.
  • Long lifespan with proper maintenance.
Cons
  • Higher upfront installation cost.
  • Requires outdoor space and specific installation conditions.
  • Needs regular servicing and occasional repairs.
  • Performance affected by extremely cold weather (though improving with modern units). Read our article on how air source heat pumps work in colder climates.

Infrared Heating vs Air Source Heat Pumps: Which Is Better for Your Property?

Choosing the right heating system depends on various factors, including your property’s size, insulation, energy goals, and budget. All of this will impact what size air source heat pump you will need.

Let’s explore critical considerations to help you decide.

Energy Efficiency

Infrared heating systems have an efficiency close to 100% in converting electricity to heat, but this does not account for how the heat is distributed. 

Since infrared heat warms objects directly, it may not be ideal for uniformly heating large or poorly insulated spaces, potentially requiring higher energy use.

Air source heat pumps, however, can deliver 3 to 4 units of heat for every unit of electricity used (COP 3-4), making them 300-400% efficient in ideal conditions. 

They distribute heat more evenly through a building’s heating system, reducing overall energy demand when paired with good insulation. For a closer look at how performance varies, read our dedicated post on air source heat pump efficiency.

Air Source Heat Pump£7,000 – £13,000 (fully installed system)Moderate to high – system upgrade may be needed3–5 days

Infrared heating panels are comparatively inexpensive and quick to install, often costing between £300 and £1,200 per panel, depending on size and brand.

Air source heat pumps require a higher initial investment, averaging £7,000 to £13,000 for a full system, including the heat pump unit, installation, and any necessary system upgrades like new radiators or underfloor heating.

However, homeowners in England and Wales may be eligible for financial support through the Boiler Upgrade Scheme (BUS), which offers grants of up to £7,500 towards installation. For more on eligibility and available funding options, read our full guide on heat pump grants.

Additionally, you can find a full breakdown of heat pump costs, including installation and maintenance factors, in our guide.

Running Costs

Infrared heaters run entirely on electricity, which in the UK can be costly, especially during colder months when heating demand is high.

Air source heat pumps consume electricity too but are far more economical over time due to their ability to extract ambient heat, leading to lower energy bills and reduced carbon footprint. For specifics, we’ve broken down typical heat pump running costs so you know what to expect monthly and annually.
