Each of us before the start of the heating seasonponders over the issue of installing more modern and, consequently, efficient equipment. Agree that the more efficiently heat is transferred from the radiator to the room, the better.
Можно говорить о том, что вакуумный радиатор heating is not a revolutionary discovery. He is known for a long time, another thing that gained popularity only in recent years. The device is quite simple. In appearance, we have a conventional sectional radiator, but not water but lithium-bromide solution is used as a coolant, which begins to boil at +35 degrees Celsius. To minimize the pressure in the system, it is necessary to completely remove air from there, hence the name - vacuum. At the bottom of the radiator water flows, which does not come into contact with the coolant. These liquids are contacted through the wall of the metal pipe. It turns out that the water warms up the coolant, and he quickly transfers heat to the radiator walls.
Since we have already met a bitdesign, I would like to better deal with the operation of the device. So, the system receives hot water, which transfers heat to the lithium-bromide solution. Due to the low boiling point, it quickly evaporates, then the condensate flows down and again turns into steam. For this simple reason, there is an intensive cooling of the lower wall of the pipe. The temperature difference contributes to an increase in heat flow.
In most cases it makes sense to think aboutpurchase of radiators of this type in the country or in a large country house. This is due to the fact that in rooms with a large area it is necessary to heat a large amount of heat carrier to a high temperature. And vacuum heating radiators can significantly reduce heating costs. Moreover, the room will warm up much faster. In addition, radiators have several sensors. When the desired temperature is reached, they will turn off themselves, and the boiler will go into standby mode. What else is interesting: absolutely any boiler will do. It doesn't matter if it works on solid or liquid fuels. Of course, one cannot say that such batteries do not have their own nuances and shortcomings, they exist. But we'll talk about this a little later. And now let's deal with the choice.
Before buying it makes sense to pay attention toproduct quality. It can be said that the liquid used as a coolant is poisonous. Therefore, you should not have any contact with her. Not to be mistaken, pay attention to the quality of the assembly, connections and tightness. Of course, the last moment is very significant, and it is almost impossible to determine it by eye, but when testing the system, everything will immediately fall into place. In principle, the amount of lithium bromide plays a role. It should not be too much. To check this, take a radiator in your hand and try to swing it. If you hear only a slight rustling, then everything is in order. When a transfusion is heard, this indicates its excess amount. Do not forget that vacuum heating radiators, the principle of operation of which we have already considered, must be completely sealed.
Согласно статистике, многие отдают предпочтение other types of heating. The reason is quite simple - the possibility of leakage from the vacuum radiator. Let it be negligible, but it is. Agree, such a device can not be put in the nursery. Well if a hole in the body is found immediately, and if not? Results may not be the best. This is perhaps the main drawback, according to potential buyers.
But there are those who respond very positivelyabout such radiators. Many say that it allows you to significantly save an average of 20-40% on electricity. You can believe this, because the boiling point of the coolant is quite low, and its heat transfer is at a high level. In addition, there are responses regarding the appearance of the slightest crack in the housing. You can be sure that in this case the room will quickly become cold. Depressurization will lead to the fact that the system will be atmospheric pressure, and this, in turn, will increase the boiling point of the coolant. In principle, these are all the advantages and disadvantages that, according to users, vacuum heating radiators have. Reviews, of course, largely depend on the manufacturer.
We can safely say that this is the mostFamous vacuum radiators of Russian-made heating. The company manufactures devices from carbon steel with a thickness of 1.5 mm. The approximate heat transfer rate of one section is 170 kW at an operating pressure of 0.6-1.3 MPa. In principle, the product can withstand a pressure of 2 MPa, and already at 5 MPa it is completely destroyed. Consumer products "EnerdzhiEko" almost no negative reviews, on the contrary, everyone is talking about the high quality of the assembly.
Can not say that such pleasure will costyou cheap Thus, a six-section battery costs about 300 euros, and a unit of 12 sections costs 550 euros. But, despite this significant drawback, electric vacuum radiator heating is acquired not only for apartments and country houses, but also for heating industrial buildings and offices. As noted above, this popularity is due to significant savings compared with cast iron and aluminum radiators.
If you do not want to pay specialists money forassembly, it is quite possible to do on their own. You may not have practical experience, but theoretical knowledge is better to get pre-typed. There is nothing difficult here, and all the work is carried out in several simple successive stages.
First you need to dismantle the old one.heating system, of course, if you have not done. For this purpose, the heat carrier is first drained. Then apply mounting points for vacuum radiators. Install the brackets and check them for stability and durability, and then hang the battery. If the mount suddenly fails, the radiator may fall and be damaged. At the next stage, ball valves are sealed. To do this, you can use a conventional sealant. It is necessary to connect the main pipeline to the cranes and re-seal the system. Please note that the abrasive cannot be used during the cleaning of joints. This is due to the fact that in the system metal particles are dangerous for the pump and seals. At the last stage the coolant is poured into the system.
Most of the advantages of such devices have already beendescribed. For example, a vacuum radiator can work both on wood, and on coal or gas. Electrical power sources are not an exception, as well as innovative solutions such as solar panels, etc. The amount of water in the system is reduced to a minimum of about 70%. It is needed only for heating the coolant. In addition, you can forget forever about what air traffic jams and rusting of the inside of the radiator. Most manufacturers have a declared service life of about 30 years, and device efficiency is 98%.
Вас наверняка интересует, почему же тогда vacuum heating radiators in Moscow, and, in fact, in many other cities of Russia are not too common? It's all about their high cost. However, in Europe, this method of heating the room is very popular, and there are not too many such radiators.
As you can see, this is quite an interesting way.heating. However, due to the high cost and possible poor-quality assembly, many consumers still prefer radiators, where water acts as the main coolant. By the way, during installation it is recommended to glue an isolon to the wall or foil, that is, a reflector. This will achieve even better effect in terms of heat transfer. As you can see, vacuum radiators have their strengths and weaknesses. But in any case, to buy them or not, it is up to you and only you. If you are confident in their security and you have free money, then why not?
