The Guide to Installing iHelios Infrared Heating: How to Calculate Materials

iHelios Infrared Electric Heating Film Calculation: A Step-by-Step Guide

Infrared heating is a modern, efficient alternative to traditional systems.
Instead of warming the air, infrared radiation heats objects and people directly, leading to more uniform warmth and potential energy savings.

If you're planning to install an iHelios infrared heating film, understanding how to calculate your materials is essential for a smooth and successful installation.

Good news: we’re happy to offer you a free heating calculation — just contact us!

Step 1: Assess Your Heating Requirements

Before calculating materials, you need to assess the heating needs of your space.
Consider these key factors:

  • Room Size: Measure the length, width, and height to calculate the room’s total volume.

  • Insulation Quality: Evaluate walls, floors, and ceilings. Better insulation reduces heating needs.

  • Window Area: Calculate the total area of windows, since windows contribute to heat loss.

  • Occupancy: Think about how many people use the room and their activities, as this affects the heat demand.

Step 2: Calculate the Heating Load

The heating load is the amount of heat energy needed to maintain a comfortable temperature.
It’s measured in watts (W) and can be estimated using this formula:

Heating Load (W) = Room Volume (m³) × Heating Factor (W/m³)

The heating factor depends on insulation quality:

  • Poor Insulation: 30–40 W/m³

  • Average Insulation: 20–30 W/m³

  • Good Insulation: 10–20 W/m³

Example: For a room with average insulation and a volume of 60 m³:

Heating Load = 60 m³ × 25 W/m³ = 1500 W

Step 3: Determine the Infrared Heating Film Requirements

iHelios infrared heating films come in different sizes and wattages:

  • iHelios iH403: 30 cm width – 66W, ceiling installation between 40 cm joists

  • iHelios iH405: 50 cm width – 110W, ceiling installation between 60 cm joists

  • iHelios iH410: 1 m width – 140–220W, underfloor installation (laminate, engineered, or wood floors)

Choosing the Right Film

  • For floors: Cover about 80% of the total floor area to avoid cold spots.

  • For ceilings: Calculate based on your heating load and selected film wattage.

Film Length Calculation

Use this formula:

Film Required (linear meters) = Heating Load (W) / Film Wattage (W)

Example:
If your heating load is 1500 W and you select iH405 (110W):

Film Required = 1500 W ÷ 110 W ≈ 13.6 meters

Power Calculation

To check your system's amperage:

Current (A) = Heating Load (W) ÷ Voltage (V)

Assuming 240V mains:

1500W ÷ 240V = 6.25A

Important:

  • If your load exceeds 16A, you’ll need either two thermostats or a contactor.

  • Always ensure safe electrical design for your heating project.

Film Placement Guidelines

  • Leave at least 200 mm between the heating film and the walls.

  • Distribute the film evenly for uniform heating.

  • Avoid placing heating film under heavy, fixed furniture to prevent overheating.

Step 4: Calculate Additional Materials

Besides heating film, you’ll also need:

  • Reflective Insulation: To enhance heat efficiency.

  • Gateway: For remote control and smart system integration.

  • Thermostats: Choose thermostats suited to your control preferences. One thermostat can handle up to 16A.

  • Wiring and Electrical Components: Plan your wiring length carefully and use compatible materials.

  • Occupancy Sensors: Automate your heating system based on room usage.
