Infrared vs Convection Heaters: Which Is Better for Your Home?
Infrared heaters and convection heaters both use heat to make a room comfortable, but the way that heat reaches you is very different.
Convection heating primarily warms the surrounding air. Infrared heating uses radiant energy to warm people and surfaces within the heater's effective coverage.
That difference can affect how a room feels, where heaters are positioned, how quickly occupants perceive warmth and how a heating system is controlled.
It does not, however, mean that every infrared heater will automatically use less electricity than every convection heater. Running costs still depend on wattage, operating time, controls, room heat requirement and electricity price.
Quick Answer
What's the Difference Between Infrared and Convection Heating?
Convection heaters warm the air, while infrared heaters transfer radiant heat towards people and surrounding surfaces.
Convection can be useful when the aim is to raise the general air temperature throughout a room. Infrared can be particularly useful when radiant comfort, individual room control, silent operation and targeted heating are priorities.
The better option depends on the room and how you intend to use the heating.

| Running cost | Depends on wattage and actual operating time | Depends on wattage and actual operating time |
How Convection Heaters Work
Convection heating works by transferring heat to the surrounding air.
As air is warmed, it moves through the room and cooler air takes its place. Some heaters rely on natural convection, while others use a fan to increase air movement.
Over time, this process raises the general air temperature of the room.
This makes convection a familiar approach for whole-room heating, but its performance depends on factors such as room size, insulation, draughts, ceiling height and the heater's location.
How Infrared Heating Works
Infrared takes a different approach by transferring energy through infrared radiation.
Instead of relying primarily on warming the room's air first, radiant energy travels from the heater towards people and solid surfaces within its effective coverage.
Those surfaces can include walls, floors, furniture and other objects within the room.
You can learn more about the principle in our science of infrared heat guide.

Energy & Running Costs
Is Infrared Cheaper to Run Than Convection Heating?
Not automatically.
For direct electric heaters, the starting point for calculating maximum active electricity cost is the heater's rated power:
Heater output in kW × operating hours × electricity price per kWh = maximum active electricity cost
A 1.5kW electric heater drawing full power for one hour uses 1.5kWh of electricity whether the heat is delivered primarily through convection or infrared radiation.
Where real-world consumption can differ is in the amount of heating output installed, how long the heaters operate, thermostat behaviour, zoning and how effectively the system matches the room's heating requirement.
Infrared can therefore create opportunities for targeted or room-by-room heating, but it should not be assumed that radiant heating automatically guarantees a lower electricity bill.

Radiant Warmth vs Warm Air
The biggest practical difference between infrared and convection heating is often the way the warmth feels.
Infrared
Radiant Heating
- Directs radiant energy towards people and surfaces
- Does not require a fan to distribute heat
- Fixed panels operate silently
- Can be positioned according to the required heating area
- Suitable for individual room or zoned heating strategies
Convection
Air Heating
- Primarily raises surrounding air temperature
- Heat circulates naturally or with fan assistance
- Can provide general whole-room air heating
- Portable options are widely available
- Performance is influenced by room heat loss and air movement
What About Dust, Allergies and Air Quality?
This area needs a little more nuance than many heating comparisons suggest.
Fixed infrared panels do not use a fan to distribute heat, so they do not create forced airflow from the heater itself.
Some convection heaters also operate without fans and rely on natural convection, while fan-assisted heaters deliberately move more air around the room.
It would therefore be misleading to claim that all convection heating actively “blows dust around” or that infrared heating treats allergies or respiratory conditions.
If avoiding fan-driven air movement is important to you, a fixed infrared panel is one heating option worth considering.

Installation and Maintenance
Installation requirements depend on the specific heater rather than simply whether it is infrared or convection.
Portable convection heaters can be straightforward to position and use where the manufacturer's instructions permit.
Infrared heaters are available in several formats. Depending on the model, they may be wall mounted, ceiling mounted or used with a suitable freestanding arrangement.
Fixed installations can have product-specific electrical and mounting requirements, so the manufacturer's instructions should always take priority.
Likewise, maintenance varies by heater design. Cleaning, electrical checks and other servicing requirements should follow the instructions supplied with the product.
See our infrared heating troubleshooting and maintenance guide for more information.
When Might a Convection Heater Make More Sense?
Convection heating can still be a practical option.
It may make sense where:
- You want to raise the general air temperature throughout a room
- You need an inexpensive portable heater for occasional use
- The heater needs to move between different rooms
- A permanent wall or ceiling installation is not suitable
- An existing convection system already heats the room effectively
Replacing a functioning heating system should therefore be considered on the basis of the complete room and usage pattern rather than technology alone.
When Might Infrared Heating Make More Sense?
Infrared becomes particularly interesting where:
- Radiant rather than primarily air-based heating is preferred
- Rooms need independent heating control
- Silent operation is important
- Wall or ceiling mounting helps keep floor space clear
- You want heating designed around individual rooms or occupied areas
- Several portable heaters are currently being used as a regular heating solution
Our infrared heating panels provide one fixed-heating option for suitable rooms.
Wattage Matters More Than the Heater Label
Whichever type of heating you choose, correct sizing matters.
An undersized heater may struggle to provide the required comfort, while installing substantially more heating output than the room requires can increase electrical demand unnecessarily.
The heating requirement should account for the room dimensions and building characteristics rather than relying on a generic heater-per-square-metre assumption.

Infrared vs Convection Heater FAQs
What is the main difference between infrared and convection heaters?
Convection heaters primarily warm surrounding air, while infrared heaters transfer radiant energy towards people and surfaces within their effective coverage.
Is infrared cheaper to run than a convection heater?
Not automatically. Running cost depends on heater wattage, operating time, electricity tariff and controls. Infrared may change how heating is zoned or operated, but the technology alone does not guarantee a lower electricity bill.
Does a 1kW infrared heater use less electricity than a 1kW convection heater?
If both draw their full rated 1kW continuously for one hour, each uses 1kWh of electricity. Actual consumption over a longer period can differ because of thermostat operation, controls and usage patterns.
Do infrared heaters heat the air?
Infrared heaters primarily transfer radiant energy to people and surfaces. Those warmed surfaces can subsequently transfer heat to the surrounding environment, so room air can also warm as part of the overall heating process.
Do convection heaters circulate dust?
It depends on the heater. Fan-assisted convection heaters deliberately move air, while natural-convection heaters do not use a fan. It is therefore inaccurate to treat every convection heater as a fan heater.
Which is better for a bedroom: infrared or convection?
Both can be suitable depending on the room and required heating pattern. Fixed infrared panels offer silent operation without a fan, while portable convection heaters may appeal where flexibility is more important. Product suitability and installation instructions should always be considered.
Infrared or Convection: Which Should You Choose?
There is no single heater type that is automatically best for every room.
Convection heating is a familiar way to raise the general air temperature and can be practical where portability or occasional heating is the priority.
Infrared provides a different heating experience by directing radiant energy towards people and surfaces. It becomes particularly attractive where you want silent fixed heating, room-by-room control, wall or ceiling installation or a heating system designed around occupied areas.
The important comparison is not simply “infrared vs convection”. It is whether the heater's output, position, controls and operating pattern are appropriate for the room you are trying to heat.
