Varieties of appliances for heating systems are constantly being improved. Naturally, each new product causes contradictory feelings: mistrust, suspiciousness, doubts about the appropriateness of use and many, many others. After all, to various "innovations" and "upgrades" we are already so accustomed to that in many ways we began to trust only ourselves.
There is no sense in explaining how infrared heaters are arranged-not the topic of the article, although some features of the text will be noted. We must immediately stipulate that it is wrong to assign certain properties to the instruments of the whole group indiscriminately. Much depends on the specifics of the application, as well as on the type of product."Infrared" are produced in 2 versions - in the form of panels and films. In addition, they are divided into gas and electric, stationary and portable. Consequently, the same characteristics apply to different models in different degrees.
We will mainly focus on electrical, since gas supply is not available everywhere. And we will talk about film( PLEN), because they are more convenient and cause the greatest number of questions. There are many articles on the Internet in which advantages are described, shortcomings are noted( sometimes casually).It's no secret that many materials are just hidden advertising, and articles are initiated by interested persons( as well as "groaning" products - often the work of competitors).Let's try to summarize all this and assess the veracity from the point of view of the "cautious philistine with an engineering education".
Than good
Small size and convenience of installation
With this it is pointless to argue. First of all, the fact that installation of many heating devices is associated with strict compliance with certain requirements. For example, boilers of high power need a separate room. For example, good ventilation, grounding, and appropriate fire-fighting measures should be provided. Whoever uses the boiler, he knows all these "delights."
IR heaters have NO limitations in terms of installation."Film" can be mounted even under the lining, so that "the eyes do not callose".And regardless where - on the ceiling, walls, in niches and so on. In general - where it is more convenient to owners.
To save energy, you can organize "point heating".For example, if in a country house in winter only 1 - 2 people live and at the same time do not use all the rooms. There are many options.
It remains to add that for the installation of "IR" will not have to issue permits and other documents.
Cost of works
Speaking about the comparative prices for traditional devices and "IR", you need to take into account that infrared heaters need a little, and in each room. And this increases the costs. But do not forget that in the classical system of heating, except, for example, a boiler, there are many other things - a pump, a hydraulic accumulator, a pipe system with shut-off valves. If you sum up all the expenses, then a decent amount of money goes. Plus - the installation fee.
Maintenance in service
Ironically, there is no such thing as the maintenance of infrared heaters. We will not recall the list of routine works for boilers. Even if there is another, less complicated device, then there is still a highway. You need to clean the filters, for example.
In addition, the absence of pipes removes such a "sick" problem from the agenda as periodic leaks and their consequences. And the "IR" pipes do not have - and problems too.
Cost-effectiveness of
Perhaps, this is the most advertised advantage. Calculation that a constant increase in tariffs forces people to look for ways to minimize payments. And involuntarily recalled the school, where in physics lessons we were told about the law of conservation of energy. The question immediately arises: how can one get the same amount of heat by spending different amounts of electric? After all, the room is alone, nothing changes in it? And energy does not disappear anywhere, it is transformed, and only. Probably, here it is necessary to talk about several other criteria.
Heating efficiency
According to this indicator, IR heaters outperform, probably, all analogs. The fact is that the other heating appliances work on the principle of heating the air, which, in turn, raises the temperature of objects. But warming up the air masses is inefficient. In infrared devices, the principle is different - about 90% of the heat energy they give to the objects in the direction of which they are directed, and only about 10% goes to heat the environment. It should be noted that this method provides a more even heating of the room, as heated walls, floors and ceilings themselves become radiators of heat.
. Energy consumption of
. Such devices consume a little energy. But you need to consider how many of them will be installed in the house. One heating will not provide. Although, given the efficiency of heat transfer, they are more economical.
Speed
The room heating is largely determined by the location of the pipes, the number of radiators. To bring the temperature to the desired value, the boiler must be properly "driven"."IR" heaters are much quicker to cope with the task.
Do not dry air
This is particularly the case with different air heaters, reflex lamps. In this respect, the "IC" instruments do not exert any influence on the microclimate.
Comfort
If, for example, mount on the ceiling, the floors will always be warm. Opinions are often expressed that IR radiation has a positive effect on the human body. But here the final word for the doctors. Noiselessness in the work-as they say, without comment.
Reliability
Firstly , a significant service life.
Secondly, , voltage surges, phase misalignments will not cause such devices to fail.
How bad is
Mounting - stationary
You can not move such a heater if you want it - it is fixed at the place of installation( with the exception of small floor models).
Minimum of
services Unlike different types of boilers, such devices do not have different functions. Only heating and disconnecting( if a timer or thermostat is installed).
The cost of the devices lies in such limits that it makes no sense to indicate. On average, PLEN for heating 15 m² will cost about 2,500 rubles( at a minimum).
Pin
"IR" heaters really have many advantages over traditional appliances. But you still need to consult with specialists. The main question is the ratio of the "quadrature" of the room with the power of radiation and in the arrangement of "IR" products. Details on the choice of such heaters you can read here.
And yet - no heating device will not provide proper comfort, if the dwelling is not additionally insulated!
