How the iHelios Infrared Heating Calculator Works
Estimated heating requirement (W) = room area (m²) × ceiling height (m) × heating requirement (W/m³).
Actual example:
Example: 20 m² room × 2.4 m height × 32.5 W/m³ = 1,560 W estimated heating requirement.
Typical Infrared Heating Requirements
| Property / insulation | Indicative starting point |
|---|---|
| Very well insulated / Passive House | 10–25 W/m³ |
| Modern well-insulated home | 25–30 W/m³ |
| Average UK home | ~32.5 W/m³ |
| Older / higher heat-loss property | 35–40+ W/m³ |
Why and should infrared heating be calculated by m² or m³?
Room volume (m³) provides a better preliminary sizing method than floor area alone because two rooms with the same floor area can have very different ceiling heights and therefore different heating requirements.

Infrared Heating Calculation Frequently Asked Questions
The amount of infrared heating required depends on the room size, ceiling height, insulation level, and installation type. Most UK homes typically require between 25–40 W/m³. Our iHelios infrared heating calculator helps estimate the correct heating output automatically.
Infrared heating is commonly calculated using room volume multiplied by a heating factor based on insulation quality. Better insulated homes require less wattage, while older or poorly insulated buildings may require higher heating output.
Typical infrared heating requirements are:
- 20 W/m³ for passive or highly insulated homes
- 25 W/m³ for modern new builds
- 30–32.5 W/m³ for average insulation
- 35–40 W/m³ for older or less insulated properties
Yes. iHelios infrared heating systems are suitable for whole-house heating, including living rooms, bedrooms, bathrooms, kitchens, apartments, offices, and commercial buildings.
Yes. iHelios infrared heating is designed to replace radiators and wet central heating systems, creating invisible, space-saving heating without pipes, boilers, or bulky radiators.
Yes. Infrared heating is becoming increasingly popular in new-build homes due to its low profile, smart zoning capabilities, and compatibility with renewable energy systems such as solar PV and battery storage.
Yes. Ceiling and underfloor infrared heating systems are ideal for renovations because they can be installed without major pipework or wet heating infrastructure.
Ceiling infrared heating:
saves wall space
provides even radiant warmth
works well in open-plan rooms
avoids furniture blocking heat
allows invisible installation
Yes. iHelios smart thermostats allow individual room zoning, scheduling, occupancy detection, and remote control through smart home integration.
