What are the disadvantages of infrared heating?

Infrared heating offers a modern, efficient alternative to traditional central heating and other convection systems—and at ARC Thermal, we’re strong advocates. But we also believe in transparency. Like any technology, infrared heating isn’t perfect for every situation, which is why it is important to know its limitations. So, what are the genuine disadvantages?

Let’s explore the practical considerations, clear up a few common misconceptions, and help you decide if tit’s the right fit for you space.

1. Infrared panels heat objects, not air, which is warmed indirectly by the thermal mass of a room (walls, ceiling and floor) absorbing the infrared and warming up

Infrared works by emitting radiant energy that directly heats people and surfaces—much like the warmth of the sun on your skin.

In practice, this “zoned warmth” is ideal for spaces where you want selective heating rather than wasting energy on unoccupied areas.

At ARC Thermal, we design heating layouts carefully to ensure even heat distribution through the room using well-positioned panels - especially in larger or more complex rooms.

Because while this delivers instant comfort and excellent energy efficiency, it means:

Less air movement

Great for air quality, but it doesn’t warm the air itself.

Targeted heating

Areas outside the panel’s line of sight may feel cooler.

2. Higher Upfront Cost vs. Conventional Heating

It’s true: high-quality infrared panels like our LAVA Basic 3.0 cost more to purchase than a basic convection heater or cheap infrared unit.

Bottom line: You may spend more upfront—but total cost of ownership over the 20 plus years is typically lower than convection systems.

But this needs context:

Our infrared panels are built to last

20+ years of service life, with no moving parts and minimal maintenance.

Lower running costs

Infrared is up to 60% more efficient than electrical storage heating systems.

No annual servicing

No water or boiler maintenance.

You may spend more upfront; but the total cost of ownership over the 20 plus years is typically lower than convection systems.

3. Needs Proper Positioning to Be Effective

For infrared to work its magic, panels need to “see” the area they’re heating. That’s why Arc Thermal provides tailored layout design and product specification - you you get optimal comfort and coverage from day one.

For proper positioning:

Wall and ceiling mounting must avoid obstructions like furniture or partition walls

Careful planning is needed in unusually shaped rooms or those with vaulted ceilings

That’s why ARC Thermal provides tailored layout design and product specification - so you get optimal comfort and coverage from day one.

4. Limited ‘Residual’ Warmth When Switched Off

Unlike storage heaters that release warmth slowly over hours, infrared only continues to heat for a limited period after it’s turned off.

There’s limited thermal inertia

from the infrared heater, but this comes from the thermal mass of the room - you feel warmth shortly after turning the infrared is turned on, but it only heats for a limited period after turning off.

This is actually a benefit

in zoned systems, allowing you to heat only the areas you need, when you need them.

Using smart controls and thermostats ensures temperature stability while keeping your bills low.

5. Surface Temperature Can Be Hot to Touch

Infrared panels reach surface temperatures of 70–120°C (depending on the product and where it is mounted), which can feel hot - though not dangerous.


Most are mounted safely out

of reach - on ceilings or high on walls.

ARC panels comply

with all relevant safety standards, and we provide clear guidance on safe clearance distances for people, pets, and furnishings.

6. Do not assume every infrared panel is the same

The quality and performance (efficiency) of infrared panels varies widely. Cheap infrared panels are less efficient and, in some cases, don’t even meet the standards that define what an infrared panels is!

You rarely win by buying cheap goods and infrared is no exception. The higher operational costs of ‘cheaper’ infrared panels quickly negates the purchase price differential.

Choosing a quality product will ensure:
-

the panel surface emits a higher proportion of infrared

the panel does not create an electromagnetic field (EMF)

But Let’s Be Clear — Some Common Concerns Aren’t Actually Disadvantages

❌ Infrared causes damp or condensation?
False - it actually reduces moisture and inhibits mould growth. That’s why it’s so effective in bathrooms, basements, and heritage buildings.

❌ Risk of fire or dangerous emissions?
Also false - infrared panels have no moving parts, no fuel, and no emissions. ARC Thermal panels are certified to the highest safety standards in the UK and EU.

Why Pay More for Premium Panels Like LAVA Basic 3.0?

LAVA Basic 3.0 is not your average infrared panel. If you’re investing in a heating system for the long-term, spending wisely upfront saves money and hassle over time.

Here’s what sets it apart:

Austrian engineered build

Consistent performance for decades

Slim, elegant design

Seamless integration into homes or studios

Suspended & ceiling options

when you have objects or furniture blocking line of sight

Ultra low maintenance

No filters, fans, or moving parts

Final Thoughts: Is Infrared Right for You?

Infrared heating isn’t perfect for every scenario - but when it’s designed well and installed properly, it delivers exceptional comfort, energy savings, and style. At ARC Thermal, we work with architects, developers, business owners, and homeowners to ensure the system is a perfect fit.
