If you’ve had a browse on our website before, you may have come across certain electric heating terminology that left you drawing blanks. Convection, conduction, and radiation are the three methods of heat transfer, and we sometimes refer to them to describe our products. But what exactly do they mean, and why do they matter? Hold off on digging out those old schoolbooks… we’re going to do this the easy way.

Conduction is how heat transfers through solid materials. Particles in solids are tightly bound together, so when one particle is warmer than the rest, through a direct heat source, it starts vibrating with energy. This causes it to collide with its neighbouring particles, making them warm up too. Eventually, this warmth spreads throughout the entirety of the solid in question, raising its temperature.
Which type of heater makes use of conduction?
It’s pretty rare to find a heater that will primarily rely on this type of heat transfer, as it’s quite impractical, not to mention rather unsafe! As you have to actually be touching a hot object to absorb its warmth through conduction, it makes sense why heating manufacturers don’t exactly jump at the idea. It does explain why the surface of electric heaters tend to be hot to the touch, though, so most heaters do produce some amount of conductive heat - just as a by-product.

Convection uses the air to transfer heat – as cold air passes over a heat source, it warms, creating a convection current. This cycle repeats again and again as long as a heat source remains stable, constantly circulating warm air.
Unlike solids, particles in the air aren’t fixed in place, so they move around freely, gaining energy like tiny indetectable Duracell bunnies. Because the particles are more spread out, hot air tends to be lighter and less dense than its chillier counterpart, which is why it rises – just think of a hot air balloon! This can create an uneven distribution of warmth, leaving the bottom half of a room colder than the top half.

Which applications does convection suit best?
As convection works quickly, it particularly suits spaces which need a supplementary heat source that gets to work fast. Conservatories, home offices, garages, and draughty spare rooms are just some of the locations that benefit from convection heaters.

We know radiation can sound daunting, but don’t fret. From your car radio to the microwave in your kitchen, we’re surrounded by safe forms of it all the time - and we really do mean all the time! As humans, we’re constantly emitting and absorbing radiant warmth. Even the light you’re using to read this sentence is a form of it. When it comes to keeping homes warm, infrared radiation is one of the most versatile, safe and effective methods. Let’s run through how it works…
Radiant warmth travels in an invisible wave to provide a direct level of heat. When these waves come into contact with an object – a person, pet, or sofa for example, heat is absorbed and transferred seamlessly. This heat is then stored in the objects themselves without getting disturbed by air movement.
Even sinking into the walls of your property, this same heat is then re-radiated back into a space, creating a bubble of comfort that can be enjoyed for hours on end. This makes it perfect as a primary heating source, as well as for something more intermittent.

Which applications does radiant heat suit best?
Radiant warmth is so versatile, there’s pretty much a heater for any domestic application. If you’ve got a chilly garage, a far infrared heater will work wonders in offsetting those uncomfortable draughts. Infrared panels can slot into any room in the house - even bathrooms! Not to mention your classic radiator… and we all know how great they are.
