How infrared heating works

1. What is the difference between an infrared heater and a conventional heating system?

Usually fossil fuels such as coal, gas, oil or electricity are used to heat the ambient air. The heated air then warms the people. With a traditional heating system, there is a constant circulation of air in the room, with warm air rising and cold air falling. Conventional heaters have a high energy loss, lead to dust floating around, dry air, mold and thus an unpleasant environmental climate.

Hoe infrarood verwarming werkt

Infrared heating provides radiant heat, similar to the effect of warm sun rays. People, walls or furniture are heated directly. Surrounding surfaces such as walls or floors reflect the heat into the room. People who are within 3 meters of the heating panel feel the heat immediately. A pleasant feeling is created, similar to a fireplace. Because the infrared C radiation penetrates deep into the skin, the temperature can be set two to three degrees lower.

The following example gives a better illustration: if we stand in the sun on a cool day, we become warm, but as soon as we stand in the shade, we become cold. While the air temperature is the same in the sun and in the shade. This phenomenon is caused by infrared radiation.

Infrared heating also offers other benefits for asthma sufferers and people with allergies, because without the air circulation generated by a conventional heater, dust particles do not float around in the room in question either.

2. More about infrared heating

Depending on the material, the front of the heating panel heats from about 85 to 100 degrees Celsius. Powder-coated steel has the best emission for infrared radiation. This infrared heating heats up very quickly and has a particularly good radiation effect. Infrared heating of natural stone takes a long time to heat up, but stores the heat for a long time and therefore radiates heat for a longer period. Our customer service team will be happy to advise you on the exact differences in surface material in order to find the right infrared heater for you.

You mount the infrared panel on the wall or ceiling. Thanks to our attractive designs, the infrared heater looks like a piece of furniture. You can connect the panel directly to the wall outlet or to the electrical network. 

Radiant heat cannot be easily measured by thermometer. Even if the room thermometer reads only 19°C and you are in the radiation area of the infrared heater, you will feel a warmth of 21 to 22°C. Because the infrared C rays penetrate deeper into the skin than just superficially heated air, a warm and pleasant body feeling is achieved.

3. What is the technology behind infrared heating?

The sun serves as the best example because it is the largest producer of infrared rays. There are 3 different types of infrared radiation.

Short wave infrared A radiation

Medium wave infrared B radiation

Long wave infrared C radiation (is used in infrared heating)

The radiation or heat wave of infrared heating consists of long wave C-radiation. Take the sea as an example. It heats up due to the infrared radiation from the sun. The air is not able to heat the air, it becomes warmer due to the heat from the sea. Like the sun, the infrared rays do not heat the air mass, but rather the surrounding objects.

4. Is infrared radiation harmless?

Life on earth would not be possible without the sun. The infrared radiation generated by infrared heating is the same long-wave C radiation emitted by the sun. This is beneficial to the body and the immune system. The surface temperature is approximately 95°C. There is no risk of burns if the surface of the infrared heater is touched. Safety sensors protect the infrared heater from overheating. Most panels are TÜV-certified and tested and therefore offer a high-quality standard.

5. Isn’t heating with electricity far too expensive and also harmful to the environment?

You can’t compare conventional heaters and direct electric heaters with our infrared heaters. These are different systems: One only generates hot air, which is also harmful to our health. The other, infrared heating, heats the walls of our homes (just as the sun heats a wall of a house). The latter is the undisputed healthier and more efficient heating method.

6. How many watts should I calculate for my apartment?

An experienced residential energy consultant will calculate the heat demand for your project (house/apartment) based on the following information:

Size of each room.

Material of the exterior walls.

Number of windows/window sections.

This calculation provides a rough estimate only, for the following reasons:

The personal heating and ventilation behavior of the occupants is different.

Usually there is no more precise information available on the thermal insulation properties of the walls.

Usually there is no technical, physical analysis of the rooms to be heated.

There are colder and milder winters, as well as longer and shorter heating periods.

If you choose our product, we will make an exact sizing of the infrared heaters based on your personal preference (how warm do you want it to be) and consumption. Because our residential energy consultant has many years of experience in this field, we can provide you with a very accurate calculation.

7. How do you heat with an infrared heater?

The indisputable feature of infrared heating is that it heats the objects and surfaces in the room, especially the walls. The walls feel warmer than the air in the room. With a conventional heater, this is just the opposite. Infrared heating uses the walls primarily as heat storage.

For example, if the infrared heater turns off or turns back by more than 2°C in the morning when you leave the house, the walls cool down too much and have to be reheated using a lot of energy. The same is true at night.

It is better and more effective not to change the temperature after it is set. Then you reach the so-called “stationary state”, that is, everything remains evenly warm (walls, ceiling, floors, furniture et cetera).

Infrared heating requires the least amount of energy to maintain a constant temperature. If you let it cool down permanently and have to warm it up again and again, it requires much more energy/electricity compared to the stationary mode. 

Compare this to cycling or jogging: if you jog or cycle at the same pace, you need much less energy than if you accelerate continuously (from slow to fast and vice versa). If you don’t believe this, try it.

Of course, there are exceptions such as the bathroom and bedroom. If the bathroom is only used for one hour a day, the temperature can be preset using a programmable thermostat.

For the bedroom, the temperature should not go below 14°C (risk of mold).
