Heat wave heating: power consumption is lower than with electric heaters

Electric heaters are still considered by many to be very expensive, not least because of the high electricity prices, and are therefore not an alternative. Heat wave heating also works with electricity, but on the contrary, the operating costs are very low here. Read more here.

The technology makes the difference

Heat wave heaters are also powered by electricity, but they work fundamentally differently than conventional electric heaters or fan heaters, and the technology here also makes the difference when it comes to consumption.

Classic electric heaters work on the convection principle, which means that they suck in cold air and release it back into the room when it is warmed up. This requires a lot of energy, because the amount of air that is in a room is quite considerable, and the air also cools down quickly, that is, has to be warmed up again and again.

With heat wave heating, on the other hand, the amount of air in a room is not heated, but only the solid bodies in the room are irradiated - the air remains at its original temperature and at the same time moist and cool. The effect is roughly the same as when you stand on a glacier on a sunny winter's day, where the heat radiation from the sun and the reflection of the glacier mean that you can endure it in a T-shirt, even when the air temperature is close to freezing point lies.

Consumption depends on the device

The power consumption of a device always counts for the consumption values. A heat wave heater with an output of 500 W also consumes half a kilowatt hour of electrical power per hour, which it then converts into heat.

The difference in consumption is only in the fact that heat wave heaters must actually run constantly in the most allest cases. Usually a few minutes per hour are completely sufficient, especially if the heater is running at regular intervals. By the short heating time compared to classic heaters, this is not a problem.

To heat a large room with a 500 W strong heat wave heating, which runs for about ten minutes per hour, costs only round 2 - 3 kWh of energy per day. Rarely used rooms, as the bathroom, can thus be heated up shortly before use.

Tips & tricks are important in the operation of infrared black beams or heat wave heaters, above all, the regular honeycomb intervals. A timer at the socket does a good job here, another, but usually more difficult alternative is control via the room temperature.
