How to calculate the number of infrared heaters for a room

Content Breakdown: What this article covers?

  • Thermal transmittance (aka U Value): Understanding how heat moves throughout a building is vital, and this is quantified by the Thermal Transmittance, commonly known as the U Value. This value plays a crucial role in understanding how heat moves through a building. In the context of calculating the heating load for a home, it’s important to note that the U Value doesn’t directly determine the coverage area for an effective heating strategy. Instead, a house’s cumulative building envelope has a set amount of U values, which equates to the number of heating panels required.
  • Determining the number of heaters required: Once the power output of each heater is established, the article delves into the intricacies of calculating the total energy required to warm the room’s volume. This calculated energy value serves as the cornerstone for deciding the optimal number of heaters needed to achieve efficient and comfortable heating.
  • Heater Placement and Distance: Logical placement of heaters is a crucial consideration. Rather than clustering them closely together, the article emphasises the strategic spacing of heaters to ensure maximal heat displacement. The goal is to offer insights that optimise their effectiveness, promoting even heat distribution throughout the entire space.

Understanding Infrared Heating Principles

When it comes to efficient and effective heating solutions, understanding the principles of infrared heating is important. Unlike traditional heating systems that rely on convection or forced air to warm a space, infrared heating systems utilise electromagnetic radiation to transfer heat directly to objects and individuals within the room.

To grasp this concept, think of how the sun warms your skin on a cold sunny day. The sun emits infrared radiation which travels through the air and heats up objects it comes into contact with – including us. Infrared heating systems work on a similar principle, emitting infrared thermal radiation at a certain wavelength that warms objects in its path. This method of heating is not only energy-efficient but also provides consistent and comfortable warmth without excessively drying out the air or stirring up dust particles like forced-air systems do.

Did you know?

A 800W IR heating system installed in an 8m2 room can increase a room’s temperature to 18°C in 10 mins, while other heating systems (2000W convection heater and 1560W storage heater) took 15 and 17 minutes respectively. [R]

For instance, imagine you’re sitting in a chilly room with an infrared heating system installed on the ceiling. As the ceiling warms up, it emits invisible light waves that travel directly downwards. When these waves come into contact with your body or objects around you, they are absorbed and converted into heat. This direct transfer of heat eliminates any loss typically associated with traditional heating methods, resulting in maximum efficiency.

Selecting the Right Infrared Heating System: Factors to Consider

When it comes to selecting the right infrared heating system for your needs, there are several factors to consider. By taking these factors into account, you can ensure that you choose an infrared heater that will effectively and efficiently meet your heating requirements.

Firstly, you need to evaluate the size and layout of the area you wish to heat. Infrared heating systems are available in various sizes and heating capacities, so it’s important to select one that matches your space appropriately. Consider factors such as ceiling height, insulation, room area, and ventilation.

Next, think about the intended use of the space. Are you looking to heat a small office or a large workshop? Different infrared heating systems are designed for different applications, so understanding your specific needs will help guide your decision-making process.

Additionally, safety considerations are paramount. For instance, if you plan to use the heater in a commercial setting where people may be working close to it, it’s important to choose a system that doesn’t reach too high a surface temperature for safety reasons.

Did you know?

Did you know? Did you know? Conventional infrared heaters typically operate at temperatures between 90°C and 110°C, often leading to the discomfort of a ‘hot head, cold feet’ sensation. In contrast, our innovative PowerBoard panel is engineered to provide efficient heating at a lower and more comfortable temperature of 55°C. This not only ensures safety in both residential and commercial environments but also allows seamless integration by embedding the panels within walls and ceilings, which can then be plastered over. The lower temperature is gentle on plaster and paint, offering you an invisible yet effective source of warmth.

Calculating the Heating Power Required [A Real Life Example]

Achieving the desired heating outcome demands precision in determining the required quantity of panels. Guidelines based on house age, thermal transmittance, and power density calculations help in selecting the appropriate panels for the job.

Here’s a real-life example demonstrating the step-by-step process for installing our PowerBoard product in a given room.

To determine the heating load (aka w/m2 or 2/m3 in spaces with room heights exceeding 3.5Meters), we use the following general guidelines.

House kwh/m2*a Value W/m2 or W/m3 requirement
100kwh/m2*a 90w/m2 or 35w/m3
70kwh/m2*a 68w/m2 or 30w/m3
45kwh/m2*a 40w/m2 or 25w/m3

We have 2 types of PowerBoard IR panels, and below is how we determine which outputs to use!

House kwh/m2*a Value PowerBoard Heater Type
100kwh/m2*a Powerboard PB-S-250W
70kwh/m2*a Powerboard PB-S-250W
45kwh/m2*a Powerboard PB-S-180W and/or PB-S-250W

Calculating The Required Number of PowerBoard Panels

Now that we’ve determined the panel type and thermal transmittance, it is time to consider the quantities required in order to create comfort heating within your environment. This can be done by following these steps:

  • Begin by assessing the ceiling area. For flat ceilings, consider measuring the floor (a quicker means of estimation).
  • Determine the square meterage (m2) by multiplying the room’s width by its length. For example, a room measuring 4 metres by 5.2 metres results in a total area of 20.8m2.
  • Measure the ceiling height, denoted as h, which, for instance, could be 2.5 metres.
  • Calculate the room volume using the formula: Volume = Area x Height. For our example, the volume would be 20.8m2 x 2.5m = 52m3.
  • Select the appropriate power density based on the house age or by using the relevant U-Value to determine the heating load requirement. For a house built in 2001, the power density might be 25 watts per cubic metre (W/m3).
  • Calculate the total power required by multiplying the room volume by the chosen power density. In our case, it would be 52m3 x 25W/m3 = 1300 watts.
  • Finally, determine the quantity of PowerBoard panels needed. Assuming a house built in 2001, opt for Powerboard PB-S-180W due to its superior insulative properties.

Thus, the required number of boards required = 1300/180 = 7.22

Therefore, 8 PowerBoard-180W are required, as we always round up to ensure adequate heat load!

Placement Guidelines for Optimal Thermal Performance

Ensuring the highest level of thermal efficiency involves adherence to placement guidelines. Whether calculating heating load based on floor area or total volume, striving for even distribution, or considering heat losses and surroundings, these guidelines provide a blueprint for maximising the effectiveness of PowerBoard heaters. Practical constraints may arise, but these guidelines offer flexibility while maintaining efficiency.

  1. Calculate the appropriate heating load based on either floor area or total volume, depending on the ceiling height. For ceilings below 3 metres, use volume; for ceilings above 3 metres, use area.
  2. When positioning PowerBoard heaters within a room or building, strive for even distribution to achieve the most effective heating.
  3. Consider the heat losses of surrounding surfaces when placing PowerBoard heaters. It is advisable to position more heat-emitting surfaces near facades and windows to cover heat losses and mitigate potential draughts. However, avoid placing radiative solutions directly opposite windows, as this diminishes heating effectiveness.

The following instructions outline the theoretically ideal placement of PowerBoard. However, practical constraints such as ceiling beams, lights, or other installations may impede this ideal placement. Additionally, cost considerations may lead to a simplified distribution of heating panels, resulting in some reduction in heating effectiveness. 

  • Position the first panel near the outer wall, closest to the window, and place the PowerBoard 600mm from the wall.
  • Space subsequent panels 1.2 metres apart (measured from the centre) across the ceiling width.
  • Distribute PowerBoard-S heaters evenly along the ceiling length.
  • Exercise caution not to install any boards facing obstructing surfaces, such as slanted walls or suspended fixtures like chandeliers, as this can impede heating effectiveness.
