Infrared heating is rapidly becoming one of the UK’s most efficient and affordable ways to heat a home in 2025. Unlike gas boilers and heat pumps, infrared delivers targeted warmth, lower running costs, faster installation and intelligent energy control that adapts to your lifestyle. In this complete guide, we break down how infrared heating works, what it costs to run, how it compares to other systems, and the real savings UK households can achieve with smart automation.
This article blends trusted facts, expert insights, and real-world considerations with a balanced perspective designed for both homeowners and professionals. It also reflects the benefits seen in advanced systems such as those offered by specialist infrared heating and insulation suppliers like iHelios.
1. What Is Infrared Heating?
Infrared heating uses radiant heat — the same type of natural warmth you feel from the sun — to warm surfaces, objects, and people directly, rather than heating the air like traditional convection systems.
How It Works
- Panels or infrared film emit long-wave radiant heat.
- The heat is absorbed by walls, floors, furniture, and people.
- These surfaces then re-radiate warmth evenly back into the room.
- This creates stable, comfortable heat without drafts or cold spots.
Because infrared does not rely on blowing or circulating air, it avoids the heat loss associated with convection heating and delivers a more efficient, more comfortable experience.
2. Why Infrared Heating Is Becoming Popular
Infrared heating is increasingly chosen for homes, rental properties, garden rooms, offices, and low-carbon new builds because it offers several clear advantages.
Key Benefits
- Up to 30–50% lower energy use compared with traditional electric heating.
- Even, comfortable radiant warmth with no air movement or drafts.
- Fast installation — often within a single day per room.
- Zero maintenance (no boilers, pumps, filters, or servicing).
- Long lifespan, typically 20–50 years or more.
- Full compatibility with smart controls, zoning, and automation.
- Helps reduce condensation and damp by warming surfaces.
- Works exceptionally well with solar and battery systems.
3. Is Infrared Heating More Efficient?
Infrared heating can be significantly more efficient than convection heating because it focuses on heating people and surfaces rather than constantly reheating moving air.
Why Infrared Is Efficient
- Less heat loss: Warm air rises and escapes quickly. Infrared heat stays in the room via warmed surfaces.
- Lower power requirement: Infrared systems typically require 30–40% less wattage for the same comfort level.
- Faster comfort: Rooms feel warm sooner because radiant heat acts on people, not just air.
- Zoning: Only heat the rooms being used, with precise control and schedules.
- Better heat retention: Warm surfaces release heat slowly, so rooms stay warm longer after switch-off.
Advanced systems with smart sensors, open-window detection, occupancy monitoring, and zoning can further improve real-world efficiency.
4. Running Costs: Is Infrared Heating Cheaper?
Running costs depend on energy prices, insulation, and user habits, but infrared consistently performs better than conventional electric heating.
Typical Running Cost Advantages
- Uses around 30–50% less electricity for equivalent comfort.
- Requires lower wattage heaters than many convection systems.
- Does not need to run constantly to maintain a comfortable temperature.
- Heat is stored in the building fabric rather than quickly lost in the air.
- Smart automation and zoning cut wasteful energy use.
For many households, this translates into meaningful monthly savings, especially when upgrading from older electric radiators or storage heaters.
5. Is Infrared Heating Good for Homes?
Yes. Infrared heating is highly suitable for a wide range of domestic applications.
Ideal Applications
- Living rooms, bedrooms, kitchens, and bathrooms.
- Renovations, refurbishments, and extensions.
- New-build properties targeting low-carbon or net-zero standards.
- Garden rooms, home offices, and studios.
- Loft conversions and attic spaces.
- Homes with solar PV and battery storage systems.
- Properties affected by damp, condensation, or mould.
Because radiant heat keeps surfaces warm, it naturally reduces the moisture that leads to condensation and mould, which is a key advantage over many convection-based heating systems.
6. Installation: How Much Does Infrared Heating Cost?
Infrared systems are typically cheaper to install than gas central heating, heat pumps, or storage heaters, particularly in existing properties.
What Makes Installation Cost-Effective
- No pipework required.
- No boiler or flue.
- No pumps, valves, or radiators.
- Minimal disruption to the property.
- Quick installation, often completed in a day per room.
Underfloor infrared film systems are especially cost-effective for retrofits because they are thin, lightweight, and can fit under most floor types without significantly raising the floor height when designed correctly.
7. What Size Infrared Heater Do You Need?
Correct sizing is essential for comfort and efficiency. Oversizing can waste energy; undersizing may leave rooms underheated.
General Sizing Guide
- 50–120W per m² for underfloor infrared film, depending on insulation and room use.
- 300–800W infrared panels for most typical rooms.
- Higher wattage in poorly insulated or very exposed spaces.
- Lower wattage in modern, well-insulated homes.
A dedicated heat-loss calculator is recommended to obtain accurate sizing tailored to your property, room-by-room.

9. Is Infrared Heating Safe?
Infrared heating is considered safe when installed and used correctly and has been used for decades in homes, healthcare environments, and industrial applications.
Why It’s Safe
- Uses far infrared, a long-wave form of heat similar to natural radiant warmth.
- No combustion, fumes, or on-site emissions.
- No moving parts and no fan-driven air circulation.
- No risk of leaks or pressure-related boiler issues.
This combination makes infrared heating suitable for families, older residents, and people with allergies or respiratory sensitivities.
10. Infrared Heating for Landlords & Developers
Infrared heating is particularly attractive for landlords, developers, and housing providers looking for a low-maintenance, efficient electric heating solution.
Key Advantages
- No annual servicing or boiler certification.
- Low running costs support tenant affordability.
- Can help improve EPC results when combined with good insulation.
- Minimises callouts linked to boiler or radiator issues.
- Long product lifespan reduces replacement cycles.
- Smart controls can limit wasteful energy usage in vacant periods.
11. Infrared Heating and Sustainability
Infrared heating fits well with the UK’s long-term transition toward net-zero and all-electric heating.
Environmental Benefits
- Zero on-site combustion and no direct CO2 emissions.
- Low power draw, especially in well-insulated properties.
- Excellent compatibility with solar PV and home battery systems.
- Long service life with minimal resource use for repairs or replacements.

- Occupancy detection to reduce heating in unused spaces.
- Open-window sensors that temporarily pause heating to prevent waste.
- 7-day schedules and advanced programming options.
- Integration with solar, battery systems, and energy monitoring tools.
In many homes, smart automation can reduce energy use by an additional 10–25% compared with simple manual control.
13. Maintenance & Lifespan
Infrared systems typically last between 20 and 30 years, making them one of the lowest-maintenance heating technologies available.
Maintenance Benefits
- No system flushing, bleeding, or pressure checks.
- No boiler servicing, filters, or pumps.
- No moving parts to wear out.
- Extremely low risk of breakdown when installed correctly.
Over the lifetime of the system, these factors can represent a significant saving compared with conventional heating maintenance costs.
14. Common Myths About Infrared Heating
“It only heats what it touches.”
In reality, radiant heat reflects and re-radiates around the room, warming surfaces and people to create a comfortable overall environment.
“It’s expensive to run.”
When sized and controlled correctly, infrared typically uses less energy than many alternative electric heating solutions.
“It dries out the air.”
Infrared does not dry the air because it primarily heats surfaces rather than blowing hot air into the room.
“It’s only suitable for new builds.”
Infrared can work very effectively in both new and existing properties, as long as system design takes insulation and heat loss into account.
