Vacuum radiators: description, principle of operation, device, prices and reviews

The inhabitants of Russia every year experience how severe the local winter can be. This leads to the need for constant costs for the modernization of heating systems, which will make it easier to survive the cold. And before each consumer of energy resources, at least once the question arose about how to save money. When vacuum radiators of heating appeared, it became much easier to answer it.

Features

As a main advantage of this solution, we can note a unique coolant circulation system. It does not need to move upwards, as it moves exclusively down the heater. In the remaining part of the radiator there is a special boron-lithium mixture. To heat one section of it, no more than half a liter of hot water is required. Compared with traditional steel or aluminum batteries, this figure is 7 times less. If we consider this mixture from the point of view of heat exchange, then it has unusual properties. Its boiling point is 35 degrees Celsius, which leads to a rapid and qualitative heating of devices such as vacuum radiators.

In addition, such batteries will never suffer from air congestion, corrosion processes and slagging of pipes. Vacuum radiators are switched on quickly. This does not require much energy and time. Heat output begins with the first minutes of a fully functioning system.

Advantages

Vacuum radiators, whose price starts from 650 rubles per section, are characterized by very high heat emission. Such a battery can work from a boiler, boiler, stove, solar collector. With their help, it is possible to heat larger areas using smaller boilers. In this case, it is not necessary to heat too much of the coolant. However, do not expect that you need much less energy. You will feel the savings, but still you will not get rid of the bills.

Vacuum radiators, reviews of which show their high efficiency, began to spread quite rapidly. In this regard, we can note a number of obvious advantages of such a solution:

- the volume of coolant used is reduced by 80%;

- the amount of heat consumed from centralized systems is significantly reduced - this indicator sometimes reaches 50%, here the benefit becomes obvious if counters are used for accounting;

- Consumption of electric energy is reduced by 30-40%;

- the process of installing the instruments is quite simple and does not differ from the installation of traditional batteries;

- outwardly it is difficult to distinguish them from the usual devices;

- Vacuum radiators are not subject to corrosion processes, there will not be any problems with the blown-up parts of the heating system;

- a small amount of coolant will circulate much more easily due to the fact that the resistance of the mass of the liquid will be reduced;

- Boiling boron-lithium mixture provides high heat transfer.

Properties

Most consumers of heating devices of different types pay attention first of all to the external appearance of devices. An important criterion is heat transfer. The length of service life is another significant factor. Many are convinced that metal devices will last longer. The safety of the heater is one of the most important factors, which is not very noticeable to consumers when buying. Of course, the cases when the low quality of the heating radiator leads to the fact that its elements do not withstand the pressure of the system or the aggressiveness of the coolant are quite rare, but they do happen.

How not to get into trouble?

When this happens, you need to spend a pretty decent amount for recovery. At the moment, only those consumers who are already faced with such a nuisance think of security. From this point of view, heating radiators are vacuum, the price of which is usually higher than that of other types of instruments, are safe. This is achieved through certain aspects of their work:

1. The number of connections is minimized. The instruments are not equipped with plugs, nipples, gaskets, Mayevsky cranes and other similar elements. Structurally it is a monolithic body, having a pair of threaded connections for connection of the heating system. It is quite difficult to depressurize such a device.
2. Vacuum radiators are characterized by the fact that there is very little traditional heat carrier in them. Even in the presence of mechanical damage, there is no need to fear the flood in the room.
3. The hydraulic head in these devices is only at the bottom. There is a through pipe through which the coolant is supplied. The pressure in the battery in the area where the secondary heat carrier is located is very low.

It turns out that in case of accidental depressurization of the system, only the device will go out of operation.

Installing Batteries

Vacuum radiators, reviews of which demonstrate all their advantages, it is quite easy to mount it yourself. For this, there is a certain sequence of actions that should be followed. If we are talking about the reconstruction of the existing heating system, then first we need to remove the old batteries. However, it is important to pre-drain the coolant. Then you can mark the places of fixing the new radiators. On the specified sites it is required to fix the brackets, on which the batteries will be later mounted. All fasteners must be as stable as possible. Now, with the help of sealant and pakli, you can proceed to mounting ball valves. To them then the main pipes will be connected . The same materials are used as a sealant.

In the end, you need to test all joints for leaks. For this, the heating system must be filled with water. To clean all surfaces to be joined, do not take abrasive materials. After them, metal inclusions may remain, which pose a danger to the sealing materials and circulating pumps used.

The result of installing such radiators will not only be the presence in your home of innovative devices and energy savings, but also faster and better heating of the room than in the case of traditional heating systems.

How to choose a vacuum radiator

Since the lithium-bromide mixture is a poisonous substance, it is required to check the degree of their reliability and compliance with the established technical standards before purchasing such batteries. The qualitative production of vacuum radiators provides several of their significant features:

- in the battery there should not be too much lithium-bromide mixture, that is, when swaying, the sound of a slight rustle should come out, and not overflow;

- the tightness depends on how smooth the welding seams on the radiator are;

- the solvent should not remove polymer-powder paint;

- the seller must have a certificate of conformity for the product.

The market mainly represents the products of the company EnergyEco, in the model range of which there are suitable options for any room. The heating devices of this brand are made of carbon steel, the thickness of which is 1.5 mm. One section is characterized by a heat output of 169 kW, an operating temperature of 110 degrees Celsius and a pressure of 0.6-1.3 MPa. With high efficiency of such devices, they have one drawback - high cost. However, this fact did not affect the demand for vacuum radiators, which increases at an enviable rate. They began to be used not only in apartments and private houses, but also in offices, in industries.

Owner feedback

Practice shows that the use of such radiators in autonomous heating systems gives a reduction in consumption by 50% for solid fuel boilers and 2.5-3 times for electric ones. This kind of devices has replaced old cast iron radiators, allowing to save energy very effectively. All user feedback testifies to the high degree of efficiency of vacuum radiators in comparison with traditional variants.

Varieties

At the moment there are already electric vacuum radiators. The principle of their work is that the flow tube was replaced by an electric heater supplemented with a thermoregulator.

Vacuum radiators have advantages and disadvantages, as already mentioned. It is important to note that if you need to quickly warm up the room, they have no equal, but if the temperature is then to be increased, then lower, then the cast-iron batteries will do much better.

conclusions

As a result, we can say that it is necessary to install vacuum lithium-bromide radiators in apartments where heat meters are used . This option is also good for autonomous heating systems. This is an appropriate option for those cases when the boilers do not give too high a temperature, since a small value is required to start the reaction.
