A large proportion of homes, buildings and premises are heated by electricity, either as the only source or in combination with biofuel or a heat pump. Radiators or convectors are often used in these contexts. What should you choose and what is what?
By far most people still choose traditional radiators over floor heating, for example. The advantages are that they are practical and easy to adjust, and easy to replace if necessary. They are also efficient, stylish and useful all at the same time, as long as they are positioned and designed correctly. Contrary to what the name implies, only a small part of the heat transfer is via radiation. The majority of the heat is transferred by convection. Convection is the term for the rotating movement of air that develops in a room where the air is acted on by a heat source. Convection works well because it evens out temperature differences in the room, and counteracts cold drafts at windows or hot air collecting under the ceiling, for example. Convectors offer an even greater proportion of the heat transfer via convection than conventional radiators. For convectors, the heat transfer via radiation is almost negligible. Forced convection means using a fan for example to increase the air flow rate.
Conventional, oil-filled or fan – that is the question
A choice the consumer faces is whether to choose a conventional electric radiator, an oil-filled radiator, or a fan convector. All three have both advantages and disadvantages. Below we have compared the standard variants of electric radiators and oil-filled radiators with Frico’s fan convector PF Smart.
PS! Do you know why our fan convector is called PF Smart? Because you can control it via an app on your smartphone so that your country cottage will be already warm by the time you arrive. We think that’s smart!
