How To Estimate How Many IR Heating Panels You Need For Your Dining Room

Infrared heating is here to revolutionise the way you heat your home. It saves you money on your energy bills and provides cleaner, healthier heat.

New technology is exciting because of what it brings, but as with vastly different product entering a market, you may be unfamiliar with the technology behind it, or even how many of the product you need.

We’re going to clear that up here, focusing in on varying sizes of dining room and how many panels you would need.

Calculating The Number Of Panels For A Room

The theory behind working out how much heat you need is simple. You first need to measure the size of your dining area (length, width and height). Multiplying the length by the width gives you the amount of floor space. Multiplying this by the height then gives you the volume in cubic metres.

Then, you will need to assess how well insulated your property is. You can get a rough estimation based on when your home was built. The table below shows the suggested power per cubic metre.

Level of Insulation

Watts per m3 Required

Poor insulation (home built pre-1930)

30W per m3

Moderate insulation (home built between 1930 – 1980)

25W per m3

Good insulation (home built post 1980, or has been recently reinsulated)

20W per m3

Now that you have this information, you’ll be able to work out the total wattage required for your dining room by multiplying the volume by the suggested watts per m3.

Please refer to our guide on how to calculate the number of panels needed for any given room for a more detailed explanation of this process.

To put this into practice, let’s look at some varying sizes of dining room based on UK averages. We’ll be considering how many people will be sat at the dining table too.

Example 1: A Medium Sized Dining Area For 6 People

Our first example is an average sized dining area, where you would have a dining table that can seat up to 6 people. It measures 3.4 x 4.4 x 2.5m.

Multiplying these numbers together gives us a volume of 37.4m3.

Given that the home was built in the mid 1970s, so it’s reasonably safe to assume that it’s moderately insulated. We’ll need 25W per m3.

All we need to do now is multiply 25W by 37.4m3, which gives us 935W.

We’ve got a few options open to us here. A single 795 x 1195mm 900W Infrared Heater would be perfect for a dining area this size. You could even opt for our Setting Sun Image Infrared Panel, and add a splash of colour to the panel.

Alternatively, a set of three identical 595 x 595mm 350W IR Heaters would also work too. We have a wide selection of image IR panels in this size too, so it would be worth considering for a dining area.

Example 2: A Small Sized Dining Area For 4 People

The dining room we’re looking at now is relatively small, where you would typically find a table that cans eat up to 4 people.

The home itself was built in 1969, but only had the walls reinsulated last year, so we only need 20W per cubic metre.

The room itself measures 2.7 x 3 x 2.5m, so the volume works out as 20.25m3.

The total wattage required for the dining room is 20.25m3 multiplied by 20W, which equals 405W.

The best option here would be to install a single 595 x 595 350W Infrared Heater, as all other panels would exceed the required power by too large a margin.

Example 3: A Large Sized Dining Area For Up To 8 People

Our last example is a big dining room with a big dining table – it can seat up to 8 people. To accommodate such a table, the room has to be 3.7 x 4.9 x 2.5m.

The volume then, is 45.325m3.

The building itself is very old, from around the 1920s, so we’ll need 30W per cubic metre.

30W per m3 multiplied by 45.325m3 gives us a total wattage requirement of 1359.75W.

One option for this particular dining area is to install a set of two 595 x 1195mm 700W IR panels, as this provides 1400W of heat.

For a more personal touch, you could get a custom image printed on your 700W panel, which essentially hides your heater, as it will appear as a framed picture rather than a panel heater.

For those who’d rather stay cooler, an option could be our 995 x 1195 1200W IR heater. It can be mounted to the ceiling, or to a wall, giving you some freedom with where you want to place it.

Ordering Infrared Panels Made Easy!

The process of working out how many panels you need is much simpler than most people initially believe. The calculations take a few minutes, and the panels themselves will help lower your energy bills and require practically no maintenance too.
