Every year, residents of Russia experience how severe the local winter can be. This leads to the need for fixed costs for the modernization of heating systems, which will make it possible to survive the cold much easier. And before each energy consumer, the question arose at least once about how to save. When vacuum heating radiators appeared, it became much easier to answer.
Features
The main advantage of such a solution is the unique coolant circulation system. He does not need to move up, as he moves exclusively down the heater. In the remaining part of the radiator is a special lithium boron mixture. To heat one of its sections requires no more than half a liter of hot water. 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 fast and high-quality heating of devices such as vacuum radiators.
In addition, such batteries will never suffer from air jams, corrosive processes and slagging of pipes. Vacuum heating radiators get into operation quite quickly. This does not require large energy and time costs. Heat transfer starts from the first minutes of the full functioning of the system.
Advantages
Vacuum radiators, the price of which starts from 650 rubles per section, are characterized by very high heat transfer. Such a battery can work from a boiler, boiler, stove, solar collector. With their help it is possible to heat rooms of a larger area using boilers of lesser power. In this case, you do not need to heat too much coolant. However, you should not expect that you will need much less energy. You will feel the savings, but you still can’t get rid of the bills.
Vacuum radiators, reviews of which show their high efficiency, began to spread quite rapidly. In this regard, a number of obvious advantages of such a solution can be noted:
- the volume of the used heat carrier is reduced by 80%;
- the amount of heat consumed from centralized systems decreases significantly - this indicator sometimes reaches 50%, here the benefit becomes obvious if meters are used for accounting;
- consumption of electric energy is reduced by 30-40%;
- the installation process of devices is quite simple and completely different from installing traditional batteries;
- Outwardly, it is difficult to distinguish them from conventional devices;
- vacuum radiators are not susceptible to corrosion processes, there will be no problems with airing of sections of the heating system;
- a small amount of coolant will circulate much easier due to the fact that the resistance of the mass of liquid will be reduced;
- boiling boron-lithium mixture provides high heat transfer.
The properties
Most consumers of heating devices of various types pay attention primarily to the appearance of appliances. An important criterion is the heat transfer. Longevity is another significant factor. Many are convinced that metal devices will last the longest. The safety of the heater is one of the most important factors that not many consumers pay attention to when buying. Of course, cases where 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 on recovery. At the moment, only consumers who have already encountered such a nuisance are thinking about security. From this point of view, vacuum heating radiators, the price of which is usually higher than the cost of other types of appliances, are safe. This is achieved due to certain aspects of their work:
- Minimized the number of connections. The devices are not equipped with plugs, nipples, gaskets, Mayevsky cranes and other similar elements. Structurally, this is a monolithic housing having a pair of threaded connections for connecting a heating system. It is rather difficult to depressurize such a device.
- Vacuum radiators are characterized by the fact that there is very little traditional heat carrier in them. Even with mechanical damage, you should not be afraid of a flood in the room.
- The hydraulic pressure in these devices is only at the bottom. Here a through pipe passes through which the coolant is supplied. The pressure in the battery in the region where the secondary heat carrier is located is very low.
It turns out that in the event of accidental depressurization of the system, the device itself will fail.
Battery Installation
Vacuum radiators, reviews of which demonstrate all their advantages, are quite simple to mount on their own. To do 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 you need to remove the old batteries. However, it is important to first drain the coolant. Then you can mark the mounting locations of the new radiators. It is required to fix brackets on the indicated areas, on which the batteries themselves will then be mounted. All fasteners should be as stable as possible. Now with the help of sealant and tow you can proceed to the installation of ball valves. The main pipes will then be connected to them . The same materials are used as sealant.
In the end, it is required to test all joints for leaks. To do this, the heating system must be filled with water. Abrasive materials must not be taken to clean all abutting surfaces. Metallic inclusions may remain after them, which are dangerous for the used sealing materials and circulation pumps.
The result of installing such radiators will be not only the presence of innovative devices in your home and energy savings, but also faster and better heating of the room than in the case of using traditional heating systems.
How to choose a vacuum radiator
Since lithium bromide mixture is a toxic substance, before buying such batteries, you need to check the degree of their reliability and compliance with established technical standards. High-quality production of vacuum radiators provides several of their significant features:
- the battery should not have an excessive amount of lithium-bromide mixture, that is, when rocking, a light rustling sound should come out, and not overflowing;
- tightness depends on how smooth the welds on the radiator will be;
- the solvent must not remove polymer powder paint;
- the seller must have a certificate of conformity for the product.
The products of EnergyEco are mainly represented on the market, in the model line of which there are suitable options for any room. The heaters of this brand are made of carbon steel, the thickness of which is 1.5 mm. One section is characterized by a heat transfer index of 169 kW, a working temperature of 110 degrees Celsius and a pressure of 0.6-1.3 MPa. With the high efficiency of such devices, they have one drawback - high cost. However, this fact did not affect the demand for vacuum radiators, which is increasing at an enviable rate. They began to be used not only in apartments and private houses, but also in offices, in factories.
Owner reviews
Practice shows that the use of such radiators in autonomous heating systems results in a 50% reduction in consumption for solid fuel boilers and 2.5-3 times for electric boilers. This type of appliance well replaced the old cast-iron radiators, saving energy very efficiently. All user reviews testify in favor of a high degree of cost-effectiveness of vacuum radiators in comparison with traditional options.
Varieties
At the moment, there are already electric vacuum heating radiators. The principle of their work is that the flow pipe was replaced by an electric heater, supplemented by a thermostat.
Vacuum radiators have advantages and disadvantages, as already mentioned. It is important to note that if necessary, they quickly have no room to warm the room, but if the temperature needs to be increased, then lowered, then cast-iron batteries will be much better.
conclusions
As a result, we can say that installing vacuum lithium-bromide radiators is in apartments that use heating meters. This option is also good for autonomous heating systems. This is a suitable option for those cases when the boilers do not give too high a temperature, since a small indicator is required to start the reaction.
