Electric Underfloor Heating vs Infrared Heating Panels – Which Is Cheaper to Run?
A practical buyer’s guide comparing running costs, comfort, installation and the best rooms for electric underfloor heating and infrared panel heaters.
Buyers comparing electric underfloor heating with infrared heating panels are usually asking the same core questions: which is cheaper to run, which feels better, which is easier to install and which is best for the room they want to heat. Both systems can be excellent, but they behave very differently.
This guide explains how each system works, where each one performs best, and why the right answer often depends more on room use, build-up and control strategy than on headline wattage alone.

How Electric Underfloor Heating Works
Electric underfloor heating uses cables, mats, foil or carbon film installed beneath the floor finish. When powered, the floor surface warms and then releases heat upward into the room. The result is a gentler, more even warmth that many buyers prefer in kitchens, bathrooms and open-plan living areas.
The system type depends on the floor finish and build-up. For example, foil systems are usually chosen for floating floors, while heating mats, loose wire and DCM-PRO are more commonly used beneath tiled floors.
Electric underfloor heating is often strongest where buyers want whole-room warmth, invisible heating and comfortable warm floors.
How Infrared Heating Panels Work
Infrared heating panels work differently from both radiators and underfloor heating. They emit radiant heat that warms people, walls, furniture and surfaces directly, rather than relying mainly on warming the room air first. That is why buyers often describe infrared warmth as feeling a bit like sunshine.
This targeted heat delivery is one reason infrared panels are popular in bedrooms, home offices, churches, studios and hard-to-heat spaces where fast perceived warmth matters. They can be wall mounted, ceiling mounted, mirrored, glass-fronted or designed as picture panels depending on the room style.
Infrared panels are often strongest where buyers want faster perceived heat, simpler retrofit installation and more targeted zone heating.
Running Cost Comparison
Running cost is never just about wattage on paper. It depends on insulation, thermostat programming, room usage, heat loss, heated area, floor build-up and how long the system actively runs.
Underfloor heating often runs as a background comfort system, especially in bathrooms, kitchens and larger open-plan areas. Infrared panels often perform best when they provide targeted heating for occupied areas or for rooms that are not used all day.
| System | Typical Output | How It Usually Runs | Common Cost Pattern |
|---|---|---|---|
| Foil / Carbon Film UFH | Usually around 100–160W/m² | Cycles to maintain floor temperature | Often efficient in insulated floating-floor rooms |
| Heating Mats / Loose Wire | Usually around 150–200W/m² | Faster tiled-floor warming with thermostat cycling | Can feel very cost-effective in bathrooms and kitchens |
| Infrared Panels | Usually around 300–800W per panel | Often used in shorter targeted heating periods | Can be cheaper in intermittently used rooms |
For underfloor heating, good insulation and floor sensing are crucial. For infrared, correct panel placement and room sizing matter enormously. That is why cost comparisons should be based on real room use, not just raw power numbers.
Comfort: Which One Feels Better?
Different Heating Feel, Different Strengths
Creates an even feeling of background warmth and warm floors underfoot.
Deliver faster perceived warmth directly onto people and surfaces.
Often feels calmer and more uniform across the whole room.
Often feels more immediate and more targeted in occupied zones.
Buyers who love warm floors usually lean toward underfloor heating. Buyers who want faster personal warmth, simpler room-by-room control or heating in spaces with higher ceilings often lean toward infrared panels.
Installation Comparison
Installation is another major deciding factor.
Electric Underfloor Heating Installation
Underfloor heating installation varies by floor finish and system type. Foil heating and carbon film are usually the most renovation-friendly for floating floors. Heating mats are quicker for regular-shaped tiled rooms, while loose wire is better for awkward layouts.
Infrared Panel Installation
Infrared panels are often simpler to retrofit because they are mounted to a wall or ceiling rather than buried beneath the floor build-up. That makes them particularly appealing when buyers do not want to lift floors or alter floor height.
If you are already replacing the floor, underfloor heating becomes much easier to justify. If you want a more straightforward retrofit, infrared panels often have the edge.
Best Rooms for Each System
| Room Type | Usually Strongest Choice | Why |
|---|---|---|
| Bathroom | Electric underfloor heating | Warm tiles underfoot make a big comfort difference |
| Kitchen | Electric underfloor heating | Even whole-room warmth and good use of floor area |
| Bedroom | Infrared panels or foil/carbon film UFH | Depends on whether you want targeted heat or hidden floor warmth |
| Home office | Infrared panels | Fast warmth in intermittently used spaces |
| Open-plan living area | Underfloor heating | Consistent background comfort across a larger floor area |
| Church / studio / high ceiling room | Infrared panels | Targeted radiant heat can outperform air-based heating comfort |
Which Is Cheaper Overall?
There is no universal winner. That mildly annoying answer is also the honest one.
Underfloor heating may be cheaper overall where the room is used frequently, the floor build-up is well insulated and the buyer wants long comfortable heating periods with even warmth. Infrared panels may be cheaper where rooms are used intermittently, zoning is important or the buyer wants fast personal warmth without heating the whole floor structure.
Choose the system that matches how the room is actually used. The cheapest heating system on paper can become the wrong system if it does not suit the room pattern.
Quick Comparison Table
| Feature | Electric Underfloor Heating | Infrared Heating Panels |
|---|---|---|
| Heat feel | Even whole-room warmth from the floor up | Faster radiant warmth onto people and surfaces |
| Best rooms | Bathrooms, kitchens, open-plan spaces | Bedrooms, offices, churches, retrofit rooms |
| Installation | More involved, depends on floor build-up | Usually easier retrofit installation |
| Visibility | Invisible | Visible wall or ceiling-mounted heater |
| Zoning | Strong with smart thermostats | Very strong room-by-room control potential |
| Comfort style | Background comfort | Targeted comfort |
Running Costs: What Buyers Need to Know
When buyers compare electric underfloor heating with infrared heating panels, the biggest question is usually not just “which uses less electricity?” but which gives the best value for the way the room is actually used.
Both systems run on electricity, but they deliver heat differently. Underfloor heating usually works as a whole-room comfort system, while infrared panels are often used as a more targeted heating solution. That means the cheaper option can vary depending on room size, insulation, how long the room is heated for and whether the system is being used as background heat or for shorter heating periods.
If you want steady comfort across the whole floor area, underfloor heating may be the better long-term fit. If you want faster, zoned warmth in occupied areas only, infrared panels can often be very cost-effective.
The main factors affecting running costs are:
- Total wattage installed
- Heated area or room size
- Electricity tariff
- Insulation and heat loss
- Thermostat programming and zoning
- How many hours the heating is actually on
Underfloor heating often feels very efficient in bathrooms, kitchens and open-plan living spaces where buyers want longer periods of even comfort. Infrared panels often feel more cost-effective in bedrooms, offices, studios and intermittently used rooms where heating can be switched on only when needed.
How Running Costs Are Calculated
The basic formula is the same for both systems:
System kW × hours used × electricity price per kWh = running cost
For example, a 0.6kW infrared panel used for 4 hours at an electricity rate of 26p per kWh would cost:
0.6 × 4 × £0.26 = £0.62
A 1.4kW underfloor heating zone used for 4 hours at the same rate would cost:
1.4 × 4 × £0.26 = £1.46
These are maximum-output examples. In real use, thermostats cycle the heating on and off once temperature is reached, so actual running costs are often lower than the headline number.

Frequently Asked Questions
Is infrared heating cheaper to run than electric underfloor heating?
It can be in rooms that are heated only when occupied, because infrared panels can deliver faster perceived warmth without heating the full floor structure. In frequently used rooms where buyers want longer background comfort, underfloor heating can be the better long-term fit.
Can electric underfloor heating replace radiators?
In many well-designed rooms, yes. Whether it works as the main heat source depends on insulation, heat loss, floor build-up and the specific system chosen.
Do infrared panels heat the whole room?
They can heat a room effectively when sized and positioned correctly, but they do so by warming people, walls and surfaces rather than relying mainly on warm air circulation first.
Which system feels warmer faster?
Infrared panels usually provide faster perceived warmth. Underfloor heating often feels slower initially but can provide a very comfortable steady warmth once the room and floor are up to temperature.
Is underfloor heating better for kitchens and bathrooms?
Often yes. Warm floors make a huge difference in tiled rooms, and many buyers strongly prefer that kind of comfort in kitchens, bathrooms and hallways.
Are infrared panels good for bedrooms and offices?
Yes. They are especially attractive in bedrooms, offices and spare rooms where buyers want responsive electric heat without lifting floors.
Do both systems need thermostats?
Yes. Good control is important for both systems. Underfloor heating usually needs a thermostat with a floor sensor, while infrared panels benefit from smart room-by-room control and scheduling.
Can I combine infrared panels with underfloor heating?
Yes. Some buyers use underfloor heating as the main comfort layer in kitchens or bathrooms and infrared panels in bedrooms, offices or high-ceiling spaces where targeted radiant heat makes more sense.
