Thanks to the highest modern technic, infrared heating solutions are also suitable for the optimisation of your private consumption by combinating photovoltaics, battery storage and energy management systems .


 


How does the infrared heating system work?

The infrared heating system is based on the principle of solar radiation. From a physical view, infrared radiation is an electromagnetic wave, which is situated below the end of the red light and which dispreads itself in free rooms with a wavelength of 780 nm until 1mm.

 

 

The heat radiation doesn't primarily heat the air, in reality ceilings, walls, objects and humans are absorbing the radiation heat. The environment saves the warmth and gives it off to the room again (secondary radiation).
Through the homogenous warming of the room there is a pleasant room atmosphere. The rising warm air avoids losses.

The combination of direct heat radiation and a higher temperature in the room (wall temperature) leads to a subjective heat sensibility, which is about 2 or 3 degrees Celsius higher than the actual room temperature.
That means, the temperature that you are feeling is higher than the actual air temperature in the room.
This phenomenon can also be observed on a cold winter´s day. Through the direct solar radiation the subjective heat sensibility is higher than the actual air temperature.

The basic rule is the following: the higher the wall temperature is, the lower is the air temperature of the room, with the same cosiness.

The comfort diagramm according to Bedford and Liese says, that, if the walls are warm, you feel the same comfort, although the the air temperature is less.
So, you can lower the air temperature of the room, and every degree less saves 6% energy.


Compared to other heating systems:  How does the infrared heating system distinguish itself?

A properly dimensioned electrical infrared heating system surpasses most of the other heating systems because as far as cosiness and comfort is concerned. It is clean, noiseless, and also maintenance-free. Via warmth radiation you can temperature living rooms very equally.

Through the exact positioning of IR-panels other comfort zones can additionally be provided with warmth. This leads to the fact, that the energy that has been fed can be used efficiently whereever it is needed. However, usual convection heating systems are using the air for the heat transfer.

The disadvantages are well-known. The rising warm air leeds to big temperature differences between the ceiling and the  floor. Whilst there is very much energy saved in the warm air layer below the ceiling, which is not accessable to the user, the cold air is situated near the floor. The user will be forced to boost the room thermostat, if he doesn´t want to suffer from cold feet.

Besides, the warm air flow whirls up dust and bacteries in the entire room, so that it is an additional burden for allergy sufferers.



 

On the contrary, infrared heating systems do not whirl up any dust or bacteries – that´s why they are very suitable for allergy sufferers and asthmatic persons. Due to the higher wall temperature, humidity gets out of the wall and rises up in the air. This lead to a better insulation as well as a better room atmosphere, prevents condensation and the formation of mould. The homogenous temperature distribution in the room increases the comfortable feeling. 

 

What are the advantages of the IR-heating system?

  • comfortable warmth – pleasant room atmosphere – no dry heating air
  • exact temperature control via modern single-room control
  • high flexibility through short heating time in comparison to central heating systems
  • easy to combine with the existing main heating system – also very suitable as additional heating system for rooms that are only used temporarily (bathroom, guest room, hobby room, holiday house, etc.)
  • allergy-friendly warmth – counteraction of mould formation
  • 100 % of the energy directly used in the room is transformed to warmth – so that there is no loss of warmth through transistion losses, buffer memories, or pipelines
  • high durability without maintenance costs (no wear and tear or corrosion)
  • quick and simple installation
  • low investment costs: compared to many other heating systems, the investment costs for infra-red complete solution are significantly lower.
  • low operating costs: through the increase of the surface temperature of the walls and the direct radiation heat the air temperature can be lowered by 2-3 degrees, at the same heat sensation. This effect is strengthened by good heat insulation which becomes better and better. Besides, the low connecting values speak for themselves: a room with 30 square meters in a new building (passive-house standard) can be heated with 900 watts. The electricity needed can be produced on your one by using photovoltaic system.

Using infrared heating systems: what are the incidental costs?

How do I recognize the capacity of a heating sytem?

The capacity of an heating system is not only visible by the power consumption, but above all by the proportion from the energy needed and the radiation emitted. So you can say that by using little electrical power a big surface should be warmed to the desired temperature .

As far as IR-panels is concerned, you should never forget to compare the size of the heating surface, not only the installed load. If you consider the physical basics (radiation law according to Boltzmann) you will see, that two panels with the same size, the same surface temperature and the same material compulsory emit the same radiation power. In this case we can say the following: the higher the installed load is, the higher is the proportion of radiation of the used energy.


What is the difference between an infrared heating radiator and an infrared heating system?

IR-radiators emit, if the core temperature is much more than 100 ◦C, primarily infrared radiaton A and B. Due to the high installed loads and the very intensive radiation cone with a reach of several meters these elements are used above all for the external areas and as hall heatings.

IR-heating panels are so-called dark radiators, which radiate infrared radiation C and which don´t emit visible lights. Because of the minimal connection and consumption values as well as the perfect proportion between the used electrical energy and the emitted heating capacity, infrared radiation C is used exclusively.

What does “heating load” mean?

The heating load calculation, which is the heat contribution needed for maintaining a certain room temperature, will me made according to the DIN EN 12831 standards and should be carried out by an architect. Thereby, every room or zone is considered separately. At the same time, when calculating, the lowest expected value of the outdoor temperature is relevant. The aim of the calculation is that there will be sufficient heating in all rooms of a building at defined outdoor temperatures. So, the heating power depends essentially from: building material, air exchange, outdoor temperature, inside room temperature. It is indicated in watts (w) or kilowatts (kw). To compare different values with each other, the performance refers to the heated area. Consequently, the relevant unit is W / m².

What does “heating demand” mean?

Heating demand (German abbreviation: HWB) is the calculated amount of energy that has to be added within the heating period per usable building are, to maintain the desired indoor temperature. The unit of the heating demand is defined in kilowatt hour (kWh). It refers to the area (m²), totalized for the period of one year (a): kWh/m²a. The heating demand primarily depends from: the “quality” of the building envelope (construction, isolation), the behavior of the user (presence, temperature of the rooms), hot water consumption and the weather. Generally, heating demand is a construction parameter and serves as a definition of the energy standards of houses.

What is the consumption of the IR-heating system?

The consumption of the IR-heating system essentially depends from the building envelope and the usage. If the IR-heating system is used as main heating system, the consumption is in the area of a modern gas condensing appliance. Although the kWh for electricity is much more higher than the kWh for gas, many saving potencials can be realized using the IR-heating system.

How does it come to energy saving?

In contrast to convective systems, infrared heating panels almost don´t produce rising warm air and thus reduce losses of warmth to the ceiling. When using a convective system for heating the room the temperature difference between ceiling and floor can be up to 8 ◦C, the temperature difference at infrared heating-systems is normally below 2 ◦C.

When letting air in the room, the fresh cool air will be heated again faster and with a minimal energy input because of the solid objects which are saved in the room shell. Through the increase of the temperature of the surface of the walls and the direct radiation heat, the room temperature can be lowered about 2 - 3 ◦C at the same heat sensibility. Thermal comfort zones can be built in a room (for example writing table, reading corner, winter garden, …) via radiation heat. Using convective systems, the whole volume of the room has to be heated completely. 

If you consider all this facts, you will note a savings potential of up to 30 % in comparison to assimilable systems when using as the main heating system. Making use of island heating solutions instead of fan heaters you can even save significantly more. It has to be remarked, that the comfortable temperature when using high quality infrared heating-systems through the direct radiation heat and the increase of the temperature of the surface of the walls (reduced heat flow from the body) is about 2 or 3 degrees lower than using common heating systems. Even if the temperature is lowered by 1 degree, the heating costs will reduce about 6 %.

Is it possible to heat an entire house with IR?

Yes. An IR-heating-system is a heating system of full value, which is very suitable for heating entire objects. What therefore is important is the proper and individual dimensioning. Infrared heating-systems of high quality are highly recommended as main heating systems for your main residence, because they offer the highest comfort. They offer the lowest acquisition costs, as well as the lowest total costs. The installation is simple, fast and clean.

Is it necessary to have my flat/house well insulated?

IR-heating systems are suitable as well as for new buildings as for (not) renovated old buildings. The important thing is the right, professional dimensioning, taking into consideration all relevant factors (amongst others the isolation,…). A good energetic building envelope helps a lot to reduce the loss of heat and to heat efficiently.

How and where can the panels be installed?

The panels are used as ceiling installation as well as wall installation. Mobile floor standing devices can also be used usefully. The important thing is that the heat waves can spread free in the room and that they aren´t misaligned by furniture or other furnishing objects.

up

Does the wall, where the heating-system is installed, become hot?

Through the low heat wave emission of the heating element to the back, the wall behind the IR-heating system will be heated slightly. Due to the equal distribution of the heat waves in the room and the determined distance from the panel to the wall, the wall won´t be heated however, but reaches, with the entire heating of the room, almost the same temperature like the rest of the walls.

How is a heating panel navigated? How can I regulate the temperature? 

The navigation of the IR- heating panel can be made by radio thermostat, socket thermostat (quick and easy installation) or by a thermostat which is fixed.

Can infrared heating systems avoid mould?

When you use the IR-heating system, the temperature of the wall is higher than the air temperature. As a consequence, the formation of mould is avoided.

Why do some lamps shine red?

Infrared lamps (also called red light lamps or heating lamps) send infrared radiation A. As the infrared area borders directly to the visible light, these lamps emit visible red light. IR-lamps are used for medical purposes, for example.

Is infrared radiation dangerous for children, animals or our skin?

No. We are permanently confronted with the infrared radiation – also known as thermal radiation. Everybody that is warmer than 1 Kelvin sends electromagnetic radiation – depending on its temperature. If the temperature rises on the surface, the intensity of the radiation increases and the wavelength becomes shorter. Up to 600 ◦C approximately, the major part of the radiation is in the infrared area, so that its invisible for human beings. If the temperature keeps on rising, the radiation becomes visible and the het colour moves from light red to (850 ◦C) to yellow (1000 ◦C) and finally to white (1300 ◦C).

Only if the surfaces are even hotter, the amount of the harmful radiation, for example the ultraviolet light, increases more and more, so that there can be a certain danger for human beings. On the contrary, infrared heating systems, which work in the invisible spectral range beyond the red light do not send any harmful radiation.

Is there a risk of burns? Which surface temperature do the heating systems reach?

The DIN EN 60335-2-30 says, that the increase in temperature – based on the ambient air temperature – from heating systems with metallic surfaces  isn´t allowed to exceed 85 kelvin, whereas heating systems with surfaces of glass or ceramic isn´t allowed to be more than 105 kelvin.

That means, that if there is a room temperature of 20 ◦C, the surfaces aren´t allowed to be warmer than 105 ◦C respectively 125◦C.

If you touch the warm surfaces you won´t suffer any burns. However, we recommend to limit the surface temperature for example in the children´s room. There is no stipulated limit for heating systems which have to be installed at a non-reachable height  > 1,8 m.



Do the heating systems produce electric smog?

High quality infrared heating systems are almost free of electric smog and fall below the allowed maximum values, that’s why there is no harmful radiation exposure. Only from the cable connection (feeder cable) electronic smog will be produced in small quantities like other household appliances do as well.

Seen from a long-term view: Is heating via electricity useful?

The gas and oil reserves aren´t inexhaustible and are prior to strong price changes. The environmental pollution of several other heating systems is well known. Heat via electricity makes sense. You can get electricity via wind energy or photovoltaic systems. This means that you are independent if you produce your own energy. Infrared heating systems, combined with green electricity (for example by photovoltaic systems) spend a new CO2 neutral source of energy and can lead to the energy self – sufficiency of the household. The increasing electronic mobility as well as the desire to use the energy more and more efficient in a “smart home”  indicate the future importance of electric heating systems.

Is it expensive to heat with electricity?

The comparison of the consumption costs demonstrates, that heat with electricity due to the higher price that you have to pay for the kwH, compared to oil or gas seems more expensive. However, if you consider the capital commitment costs and the company tied  osts , an infrared heating system offers considerable economical advantages, primary in buildings which need few energy.

If you make use of old night storage heating in old buildings, the application of an infrared heating system leads to a lower consumption due to the better controllability. If an economic operation is possible depends fundamentally from the local rates for night storage heating systems and electric direct heating systems.

We highly recommend to compare the total heating costs, consisting of capital, consumption and company tied costs with the respective heating system.

up

Are there any studies regarding the high durability of IR-heating systems?

There are single manufacturers that are doing endurance tests and who permit external monitoring. We don´t know anything about official studies.  As there are no mobile parts installed in an infrared heating system, the durability merely depends from the temperature resistance of the materials used. Therefore, the durability can be much more than 20 years.
