iHelios IR Heating Film vs Radiators

Load video: See the difference between Infrared heating film and radiators


Picture two neighbouring rooms, each heated in a different way. In the first, iHelios infrared heating film is fitted in the ceiling, sending gentle, radiant warmth straight to people and surfaces below. The effect is like basking in natural sunlight – everything warms evenly, without unnecessary heating of the air. In the second, a traditional radiator system pushes warm air upward, leaving cooler zones at floor level. Heat takes longer to reach the occupants, while circulating air stirs up dust. Side-by-side, the difference is clear: infrared delivers fast, even, targeted comfort, while conventional convection heating can be slower and less consistent.

Infrared heating transfers heat to surrounding surfaces and occupants through radiant energy while also warming the room air indirectly. Because the heating element covers a large surface area, the system can operate at relatively low surface temperatures when correctly designed.

Heating performance depends on the property’s heat loss, installed output, available heated area, insulation, controls and chosen floor or ceiling construction.

Our advanced electric ir heating systems combine the efficiency of radiant infrared technology with modern ease of installation. Designed for underfloor or ceiling integration, the iHelios system is sleek, silent, and unobtrusive—perfect for any living space.

Fully certified with the UKCA Declaration of Conformity for Health, Safety, and Environmental Protection, iHelios represents a breakthrough in sustainable home heating. It’s the ideal choice for those seeking energy-efficient, environmentally friendly heating solutions that are compatible with smart home technology.
