Warm air rises naturally. So why still use a SpeedComfort?

Bas van den Berg from Nijmegen admits that he was certainly not a high flyer in physics. He does remember one thing, though: warm air rises on its own. So why, he wonders, does he need a SpeedComfort that does the same thing? We are happy to explain.

You are absolutely right! You paid good attention in physics. That is the principle of a radiator: it draws in cold air at the bottom, after which the air slowly rises along the heating surface. This is called convection. You don't have to do anything; it happens automatically.

Accumulated heat

You can feel a ‘but’ coming on. Exactly. The rate at which this air circulation gets going is quite slow. Moreover, the warm air can accumulate at the top of the room. That is not very useful when you are sitting comfortably on the sofa.

Active air displacement is a good idea

That is why active air displacement is a good idea. This way, the heat spreads faster through the room. And the heat in the room is also distributed more evenly. With the SpeedComfort—which you place under the radiator—you give the air circulation in the room just that little extra boost. Without having to turn up the thermostat.
