To calculate your iHelios infrared heating film needs, first determine the room’s heating load in watts by multiplying its volume (m³) by a heating factor (10-40 W/m³ based on insulation). Then, divide the total heating load by the wattage per meter of your chosen film to find the required length. We are also happy to create a free calculation for you.
Calculating the right amount of iHelios infrared heating film is key for an efficient system. You’ll need to assess your room’s size and insulation to determine the total heating load in watts. From there, you can calculate the length of film needed based on its wattage. This guide walks you through each step, from measuring your space to selecting additional components.
Infrared heating is different from traditional systems. It uses infrared radiation to heat objects and people directly, while conventional systems warm the air. This direct approach can lead to more uniform heating and potential energy savings.
If you’re considering installing iHelios infrared heating film, understanding how to calculate the necessary materials is crucial. Here’s a comprehensive guide to help you through the process.
How to Calculate Your Heating Needs: A Step-by-Step Guide
Step 1: Assess Your Heating Requirements
Before you start, determine the heating needs of your space. Consider these factors:
- Room Size: Measure the length, width, and height of the room to calculate the total volume (m³).
- Insulation Quality: Assess the insulation in the walls, floor, and ceiling. Better insulation reduces the heating power required.
- Window Area: Calculate the total area of windows, as they significantly impact heat loss.
- Occupancy: Think about how the room is used, as this influences heat requirements.
Step 2: Calculate the Heating Load
The heating load is the amount of heat energy (in watts) needed to keep your space comfortable. Use this formula to estimate the heating load:
Heating Load (W) = Room Volume (m³) × Heating Factor (W/m³)
The heating factor depends on your insulation quality:
- Poor Insulation: 30-40 W/m³
- Average Insulation: 20-30 W/m³
- Good Insulation: 10-20 W/m³
For example, a room with average insulation and a volume of 60 m³ would be:Heating Load = 60 m³ × 25 W/m³ = 1500W
Step 3: Determine the Infrared Heating Film Length
iHelios infrared heating film comes in various sizes and wattages. Choose the film based on your calculated heating load and where you plan to install it (ceiling or floor).
- iHelios iH403: 30cm width, 66 Watts (for ceilings with 40cm joists)
- iHelios iH405: 50cm width, 110 Watts (for ceilings with 60cm joists)
- iHelios iH410: 1m width, 140-220 Watts (as underfloor heating film for laminate, engineered, and wood floors)
For floors, aim to cover 80% of the area to avoid cold spots.
For ceilings, calculate the required length of film by dividing the total heating load by the film’s wattage. For a 1500W heating load using iH405 (110W) film:Film Required = 1500W / 110W = 13.6 linear meters
To calculate power in amps (A), divide the total heating load by the voltage (V):1500W / 240V = 6.25A
If your required power exceeds 16A, you must use two thermostats or install a contactor.
Placement: Cut the heating film into lengths that will be at least 200mm away from the wall at both ends. Distribute it evenly for uniform heating.
Step 4: Calculate Additional Materials
Besides the heating film, you’ll need other materials for the installation:
- Reflective insulation
- Gateway
- Thermostats (one thermostat can handle up to 16A)
- Wiring and electrical components
- Occupancy sensors for automatic control
You can also choose our pre-packaged kits of electric heaters.

Frequently Asked Questions (FAQs)
What is the most important factor in calculating heating needs?
Room size (volume) and insulation quality are the two most critical factors. A well-insulated room will require significantly less power to heat than a poorly insulated one of the same size.
Why do I need to leave a gap between the film and the wall?
A: Leaving a gap (at least 200mm) at each end ensures proper operation and safety. It prevents the film from being damaged by fixtures or fittings close to the wall and allows for correct wiring connections.
Can I install infrared heating film myself?
While it is possible for a competent DIYer, all electrical connections must be made by a qualified electrician to ensure safety and compliance with regulations. We recommend professional installation for the best results.
How many thermostats do I need?
One thermostat can typically control a load of up to 16 amps. If the total amperage of your heating film in a single zone exceeds this, you will need to either split the zone across multiple thermostats or use a contactor.
Do I need special insulation for infrared heating?
Yes, using reflective insulation behind the heating film is highly recommended. It reflects the heat into the room, preventing heat loss through the ceiling or floor and increasing the system’s overall efficiency.
