Decision Guide

Use this guide to quickly decide whether this product is the right fit for your room, installation type, and heating goals.

Product decision guide: This product is intended to help buyers decide if it is suitable for their room, project, installation type, heating expectations, and retrofit needs. It includes ideal use cases, non-ideal use cases, how it works, sizing guidance, installation requirements, comparison content, and frequently asked questions.

Best for

  • Complete room heating systems
  • First time infrared installations
  • Renovations and extensions
  • Garden rooms and loft conversions
  • Electric-only homes
  • Room-by-room zoned heating projects
  • All core components together

Not ideal for

  • Outdoor installations
  • Projects requiring very fast hot air heating
  • Areas needing temporary portable heating
  • Replacing a heating without heat design

How it works

This kit provides a full radiant heating system using carbon infrared film. The film heats walls, floors and objects directly rather than heating the air.

Because the building fabric stores heat, the room stays comfortable at a lower thermostat setting. The self-regulating PTC layer automatically limits temperature and works with an electronic thermostat for accurate scheduled heating.

Quick Decision Guide

Choose multiple zones rather than one large zone for better efficiency. For underfloor or ceiling install.
Do not install under fixed furniture or kitchen units.

Comparison

Compared to electric radiators this system is recommended when whole-room heating, even temperature and free wall space are required, but not recommended when the user needs instant heat or cannot perform installation work.

Compared to panel heaters this system is recommended for comfort heating in occupied rooms and when avoiding cold spots matters, but not recommended for temporary plug-in heating or rental situations where modification is not allowed.

Compared to heat pumps this system is recommended for apartments, retrofits, single-room heating, or properties without outdoor unit space, but not recommended where a full wet low-temperature system already exists.

Compared to water underfloor heating this system is recommended for fast retrofit, minimal floor height increase and zoned heating, but not recommended when a new concrete slab or high thermal mass system is planned.

What is an infrared heating film kit?

An infrared heating film kit is a complete electric radiant heating system that includes heating film, connectors, wiring and installation materials. It provides a ready-to-install solution for underfloor or ceiling heating without needing additional components.

What is included in this heating kit?

This iHelios kit is supplied with all essential installation components, including:

  • Infrared heating film (500mm wide)
  • Connectors and crimp lugs
  • Jointing and insulation tapes
  • Electrical wiring
  • Installation guide

This ensures a complete, system-based installation rather than sourcing individual parts separately. 

Can this kit be used underfloor?

Yes. The system is designed for underfloor infrared heating beneath suitable floating floors such as laminate and engineered wood, when installed with proper insulation and layout design.

Can this kit be used in ceilings?

Yes. The same system can also be installed as a ceiling infrared heating solution, making it ideal for retrofits or rooms where lifting floors is not practical.

Key Features

  • Complete Heating Kit: Includes film, connectors, wiring and installation materials.

  • Underfloor & Ceiling Use: Flexible installation for multiple applications.

  • Ultra-Thin Design: Minimal impact on floor height or ceiling structure.

  • Energy Efficient: PTC self-regulation helps reduce unnecessary power use.

  • Invisible Heating: No radiators, no pipework, no visual clutter.

  • Maintenance-Free: No servicing, pumps or water systems required.

  • Smart Control Ready: Works with app-based thermostats for zoning and automation.
