Everything about infrared

Heating with infrared is perfect for homes, offices, restaurants or even warehouses: Infrared heating panels can be used flexibly in many ways. Read here how they work, how they are constructed and what makes them so special compared to conventional heating systems.

What is infrared?

The Latin component of the name "infra" means "below", so infrared is strictly speaking "below red". This refers to its frequency within the electromagnetic spectrum. Besides the colors visible to humans, which are within the spectrum, the low-frequency UV light as well as the high-frequency infrared radiation is invisible to humans. However, this does not mean that we do not perceive infrared radiation: For example, the cosy warmth of a tiled stove or the warming rays of the sun on the skin on a cold winter's day are just a few examples of how we perceive its warmth as pleasant in nature and in everyday life.

In contrast to UV radiation, infrared radiation is not harmful to us. For our infrared wall heaters as well as infrared heating panels, infrared C, that is far infrared radiation, is used in which people can stay absolutely safely without restriction.

How does an infrared heater work

In general, infrared heating panels consist of a heating element through which electricity flows and a housing. At the same time, this heating element is an electrical resistance: In principle, 100% of the electrical energy is converted into heat and radiated in the form of infrared radiation.

This has many advantages compared to the widely used convection heating. With an infrared panel, the ambient air is not heated first, which can lead to air and dust turbulence and a very uneven temperature distribution in the room, but it has a direct effect on objects and people in the room. The heat is stored by the objects and walls of the room, which is why even when ventilating the room does not immediately cool down completely. This in turn has the pleasant side effect of effectively reducing and combating mold, as damp walls are dried by the infrared panels.

One of the highest radiation
efficiencies on the market!

To determine how efficient an infrared heating panel is, it is worth looking less at the wattage and more at the radiation efficiency. It describes how much of the electrical energy supplied is actually delivered to the surfaces of the room as infrared radiation power.

Security as a quality factor

Since its foundation in 1883 - in a time of rapid development and spread of electrical engineering - the ÖVE Austrian Electrotechnical Association has set itself the goal of ensuring the safe use of electrotechnical devices and systems. In line with this goal, the association issued the first safety regulations for electrical engineering as early as 1889.

Today, more than 130 years after its formation, the founding goals of the ÖVE are still valid: With its core areas of electrotechnical standardization and certification, the association stands for safety and technical advancement and thus also for economic advancement. With its activities, it supports the economy in the global market and objectively and independently ensures compliance with national as well as international standards and guidelines.

4 easy steps

How do i plan my infrared heating?

Which heating panels you need and where they can be placed depends on the conditions of the room or building you want to heat. In addition to the size of the room, its quality is also relevant (for example: How is the room insulated? Are there many window fronts?) and what room temperature should be reached with the heating.

1. Determine demand

In order to determine the optimal dimensioning of an infrared heater for your needs, you must first calculate the heating load. With our calculator you can quickly and easily perform a heating load calculation according to DIN EN 12831.

A basic room height of 2.60 m is
used for the calculation.

no insulation 150-250 Watt/m²
bad insulation 100-150 Watt/m²
medium insulation 50-100 Watt/m²
good insulation 10-50 Watt/m²
passive house 0-10 Watt/m²

2. Place heating panels correctly

In principle, you can install the panels on the ceiling, as well as on the walls. A stand is also possible in order to place the infrared panel flexibly in the room.

However, when placing, pay attention to the following:

  • Do not install the infrared panels opposite reflective surfaces such as glass or windows. Due to the reflection, the heat cannot be stored well and energy is lost. The same applies to glazed tile surfaces, such as those found in some bathrooms.
  • The radiation from the panels should not be obstructed by curtains or furniture that is too close together, such as a couch.
  • In older buildings or rooms with a damp outer wall, installation on the inner wall is a good idea. As a result, the outer wall is directly irradiated and dried.
  • If you choose to mount the infrared panel on the ceiling, do not position it directly above a seating area. Some find the direct radiation from above unpleasant.

3. Choose product

Once you have determined your needs and found a suitable position for your heating panel, you now have to decide: square, oblong, small or large? In our assortment you will definitely find an infrared panel according to your imagination.


With our panel assortment you are flexible: We offer you a diverse range of sizes and of course there are also matching ISOLED light frames.

4. Planning the control

The control system that is best suited for your heating solution depends primarily on how many infrared heating panels you are using. If you want to control several panels, our room thermostats are suitable in combination with our switching actuators (also flush-mounted).


How does a thermostat work?

In principle, a thermostat compares actual and set temperature. This means that if the actual temperature is lower than the target temperature, the infrared heater switches on until the specified target temperature is reached. Thermostats have various functions for optimized heating operation for individual needs, e.g.:
  • Night reduction
  • Daily or weekly programs
  • Party mode
  • Frost monitor
With the daily or weekly program, you can configure exactly what temperature you want your rooms to have at what time. For example, it can be set that at 7:30 when leaving the house, the infrared panel stops heating and the temperature is lowered by 4°C as long as the apartment is empty. These daily programs significantly reduce the switch-on time of the infrared heater, which has a positive impact on electricity consumption.

Control via a SmartHome system is particularly practical for this, as the settings of the infrared heating can be accessed from anywhere and changes can be made if necessary.

Place thermostats correctly

Not only the placement of the infrared panels, but also the thermostat is essential for efficient heating. Because: the temperature is measured where the room thermostat is placed. Therefore, care should be taken to ensure that the thermostat is not too close to the heater or other heat sources. Otherwise the temperature measurement of the thermostat can be falsified and the desired room climate cannot be achieved. The same applies to very cool places like window sills.

Unsuitable places for a thermostat are also

  • Places which are permanently exposed to strong solar radiation
  • behind curtains
  • in or behind furniture

Heating with electricity has a bad reputation and is considered to be very expensive. However, with infrared heating panels it is possible to heat efficiently and inexpensively. The investment in infrared pays off in several ways, because compared to conventional heating systems, the acquisition costs are significantly lower (up to 70%) and there are no maintenance or additional costs. In connection with a photovoltaic or wind system, heating with infrared is also 100% ecological.
Also in view of the uncertain future of conventional heating systems, it is worth switching to infrared. In Austria, all existing oil-fired heating systems must be replaced by 2035, and gas-fired systems by 2040. In Germany, too, oil and gas heating systems will no longer be allowed to be installed from 2026 onwards, as every new heating system must use 65% renewable energies. Similar developments can also be observed in Switzerland. A low-energy house with 120 m² and an electricity price of 0.2 € per kWh were used as the basis for the following calculations.

A major advantage of infrared heating compared to the water-bearing heating systems shown in the diagram is the fact that the electrical energy is converted directly at the point of use without any line losses. Depending on the condition and insulation of the pipework, water-bearing heating systems cause line losses of up to 30% of the energy used.

Uniform heat development and more space!

Infrared heating panels primarily heat surfaces and walls instead of air. This effectively prevents condensation from warm air on cold walls and combats mold growth. It is therefore also ideal for the hobby room and rooms that are rarely used or are usually cool.
