An Infrared Heater Calculator can be used to work out the size of the heaters that you require.

It is easier and more accurate to do this calculation by hand. The formula is listed below.

We supply a wide range of infrared panels specially designed to heat up an array of different sized rooms and other spaces. There are a number of things to consider when you want to install infrared panels into your home or business.

When installing a panel it will be most effective if it is fitted to the ceiling.

If the room you are wanting to heat is quite long like a lounge/diner for example or it is an L shape room, then it is better to use two smaller panels evenly fitted on the ceiling or spaced along the wall.

Just remember that it heats up what is in the line of site of the panel.

Whilst it will heat up a whole room over time, anything not inline with the panels will take longer to heat up.

The panels will provide a more even heat if they are placed in the middle of the room or spaced at equal distances. However, it is perfectly ok to fit a panel closer to the seating area of a room if you want to get the most from the heater in the shortest time.

They can also be, but do not need to be, directly above the seating.

Objects absorb, radiate and reflect infrared rays. This differs depending on the object, Metals reflect more than walls for example and windows, whilst reflecting some rays will allow them to pass through losing the bounce effect that you get from other objects.

When fitting a panel to a wall, try not to fit a panel opposite a window as the infrared rays will pass through the glass, making them less efficient as the heat is not absorbed as well. If the room is poorly insulated or prone to drafts then it is a good idea to get a size bigger then the chart below suggests.

We can, of course, offer you detailed advice on this, and if necessary visit your home or other premises to discuss your specific requirements and suggest various options that would work for you.

Here is a general guideline to calculating the wattage of panel required to heat your space.

Size of the room in M3

Multiply the width and length of a room by the height to get the cubic metres.

Example L 3m x W 3m X H 2.4m = 28.8m3

Then multiply the cubic metres of the room by 25 to give you an average wattage required.

Example – Room space to be heated 28.8m3 X 25 = 720Watts

Poor Insulation

If the room is poorly insulated or has a lot of windows or large patio doors then you need to add between 10% and 20% to the resulting number above.

Example – poorly insulated room with large window – Basic requirement = 720 W + 20% = 864Watts required.

With a poorly insulated of difficult to heat room then it may well be better to use two smaller panels fitted evenly across the ceiling or spaced out on the walls than one large unit. Whilst the initial purchase cost is higher, they can often be more efficient at heating these types of room and therefore cheaper to run.
