Radiator Size Calculator

One of the most commonly asked questions is “how powerful an infrared panel heater do I require for my room?”. As we have mentioned many times on the website, our technology is 3x as efficient as conventional radiators, so you will probably be surprised by how little power you require to warm your room.

You’ll also probably be surprised to find out just how easy it is to work out the output required for your room. In short, the wattage output required is the cubic volume of the room in meters squared multiplied by 25.

To give a working example:

Room size, in meters = 2.5 x 2 x 2.4m, therefore the cubic volume (multiply the three dimensions together) is 12 meters squared.

Multiply this number by 25 and you get 300, so for this room you would need a 300 watt infrared radiator. This would make our smallround at 310w ideal for this space. Remember that unlike convection heaters our radiators can also be mounted anywhere you like within the room (including the ceiling) without any effect upon heating efficiency.
