Surface heating in the wall - Electronic / infrared on the rise

Surface Heaters Electronic / Infrared are currently being advertised like no longer. They also bring several benefits to homeowners:
The surface heating should generate a very pleasant heat. Because it creates a pleasant, constant indoor climate by uniformly heating all the bodies in the room through heat radiation. It consumes no oxygen and the heat is generated evenly and without drafts. The humidity remains constant, the heater generates heat where it hits. Since the body surface is also heated, this heat should be perceived by humans as particularly pleasant. Even with the same level of warmth one should manage with two to three degrees less temperature in the room. Whether this is the case, you would have to decide on personal warmth feeling. The fact that these two to three degrees can result in up to 70 percent heating savings, as some manufacturers claim, experts consider questionable.
In this type of heating no dust-laden air is circulated, the dust should even prefer to deposit on the heating surface. That would not only be beneficial for allergy sufferers, but would also speed up the dusting. The surface heating in the wall makes the unfavorable radiator history. Surface heating should be maintenance-free, maintenance costs such as chimney sweep, cleaning, exhaust gas measurements, tank or boiler monitoring are thus eliminated. Only one electronic component may fail.
Surface heating electronic / infrared - ecologically controversial and economically questionable
Of the
The key criticism of electric heating concerns the energy source, especially if the surface heating in the wall with conventional electricity (instead of green electricity) is operated. Electric heating generates electricity from electricity that comes from power plants. The largest part of the electricity is generated in Germany via fossil fuels and nuclear power. In 2010, lignite, hard coal and natural gas supplied about 55 per cent of the electricity from the power plants, and about 22 per cent came from nuclear energy. Fossil energy is finite, nuclear power is being abolished. Not only that these energies are indirectly used by an electric heater, they are also used very inefficiently. Because the power plants currently have the energy experts only an efficiency of about 38 percent. In order to obtain one kilowatt hour of electricity, the energy value of around three kilowatt hours of oil must be consumed, which can not be ecologically sensible. Of course, conventional heating also uses fossil energy such as oil or gas. The modern ones
However, condensing boilers also use a high degree of this energy for heat generation, as is the case when heating with electricity, around two thirds are not lost.
Economically, the electric heater is usually not recommended for heating the whole house. This can easily be recalculated on some manufacturer's website, which also provides a calculation program for determining the required calorific values: For a small model house with 6 rooms (4 rooms with a window, 2 rooms with 2 windows, a total of 100 square meters, normal isolated new building with a U value of 0.3) recommended the calculation program on the page Watt numbers per room, which would consume about 105 kilowatt hours of electricity in 24 hours (the heating of the corridors was not considered in the model calculation). That would result in a month with 30 days about 3,175 kilowatt hours of electricity consumption, which would cost € 476.25 with a favorable electricity tariff of 15 cents per kilowatt hour. In the month!
Surface heating with green electricity or own solar system / photovoltaic system
If you run the surface heating in the wall with green electricity, the environmental balance may look different. Whether a green electricity contract really comes from green power, must be checked for each individual power contract. Many providers mix conventional electricity from fossil fuels or nuclear energy, only special test labels provide security. If you
Generating your own electricity from solar or photovoltaic systems, you can be sure that the electricity comes from renewable sources. But even in this case, environmental experts refer to this stream as too valuable for burning, it should be better fed into the grid, to help reduce the proportion of problematic energy to the total flow. In addition, in this case, heating with electricity does not make economic sense, because you receive a feed-in tariff for self-generated electricity when you feed into the power grid. What feed-in tariff will look like from 1.7.2011 is still unclear. If you count on the lowest value expected by experts of around 24 cents, you will get: 24 cents per kWh of electricity you will miss if you use it for heating. That would be a very expensive heating.
Electronic / infrared heating can therefore only make sense as an additive.It is conceivable, for example from the viewpoint of increased comfort in temporary operations, to use the surface heating in the wall as additional heating within an overall concept.
