Inhabitants of Russia every year experience for themselves 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 much easier to survive the cold. And every consumer of energy resources at least once faced the question of how to save money. When vacuum heating radiators appeared, it became much easier to answer it.
Features
The unique coolant circulation system can be noted as the main advantage of such a solution. It does not need to move up, as it only moves down the heater. The rest of the radiator contains a special boron-lithium mixture. To heat one of its sections, no more than half a liter of hot water is required. Compared to traditional steel or aluminum batteries, this figure is 7 times less. If we consider this mixture withfrom the point of view of heat exchange, 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 locks, corrosion processes and slagging of pipes. Vacuum heating radiators are put into operation quite quickly. This does not require large energy and time costs. Heat dissipation begins from the first minutes of the full functioning of the system.
Dignity
Vacuum radiators, the price of which starts from 650 rubles per section, are characterized by very high heat transfer. Such a battery can operate from a boiler, boiler, stove, solar collector. With their help, you can heat larger rooms using boilers of lower power. In this case, it will not be necessary to heat too much coolant. However, do not expect that you will 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:
- 80% reduction in the amount of coolant used;
- the amount of heat consumed from centralized systems is significantly reduced - this figure sometimes reaches 50%, here the benefit becomes obvious if for accountingcounters are used;
- 30-40% reduction in electricity consumption;
- the installation process of devices is quite simple and does not differ at all from the installation of traditional batteries;
- outwardly they are difficult to distinguish from familiar devices;
- vacuum radiators are not subject to corrosion processes, there will be no problems with the airiness of sections of the heating system;
- a small amount of coolant will circulate much easier due to the fact that the resistance of the liquid mass will be reduced;
- Boiling boron-lithium mixture provides high heat transfer.
Properties
Most consumers of heating devices of various types pay attention primarily to the appearance of devices. Heat dissipation is also an important criterion. The length of service life is another significant factor. Many are convinced that metal devices will last the longest. The safety of a heater is one of the most important factors that not so many consumers pay attention to when buying. Of course, cases when the low quality of a heating radiator leads to the fact that its elements cannot withstand the pressure of the system or the aggressiveness of the coolant are quite rare, but they still happen.
How not to get into trouble?
When this happens, it requires a pretty decent amount of money to recover. At the moment, only those consumers who have already had toface such a problem. 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 through certain aspects of their work:
- Minimized number of connections. The devices are not equipped with plugs, nipples, gaskets, Mayevsky taps and other similar elements. Structurally, this is a monolithic body with a pair of threaded connections for connecting the heating system. It is quite difficult to depressurize such a device.
- Vacuum radiators are characterized by the fact that there is very little traditional heat carrier in them. Even if there is mechanical damage, you should not be afraid of a flood in the room.
- Hydraulic pressure in these devices is available 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 itself will fail.
Installing batteries
Vacuum radiators, reviews of which demonstrate all their advantages, are quite easy to mount on your 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. After that, you can mark the places for attaching newradiators. Brackets are required to be fixed to these areas, on which the batteries themselves will then be mounted. All fasteners must 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.
At the end, you need to test all joints for tightness. To do this, the heating system must be filled with water. Do not use abrasive materials to clean all mating surfaces. They may leave metallic residues that are hazardous to the sealing materials used and circulation pumps.
The result of installing such radiators will not only be the presence of innovative devices in your home and save energy, but also faster and better heating of the room than in the case of using traditional heating systems.
How to choose a vacuum radiator
Because lithium-bromide mixture is a poisonous substance, before buying such batteries, it is necessary to check the degree of their reliability and compliance with established technical standards. Quality production of vacuum radiators provides several of their significant features:
- there should not be an excessive amount of lithium-bromide mixture in the battery, that is, when rocking, the sound of a light rustle should come out, and not overflowing;
- tightness depends on how even the welding seams are onradiator;
- solvent should not remove polymer powder paint;
- the seller must have a certificate of conformity for the product.
The market is mainly represented by EnergyEco products, in the model range of which there are suitable options for any room. Heating appliances of this brand are made of carbon steel, the thickness of which is 1.5 mm. One section is characterized by a heat transfer rate of 169 kW, an operating temperature of 110 degrees Celsius and a pressure of 0.6-1.3 MPa. Despite the high efficiency of such devices, they have one drawback - high cost. However, this circumstance 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 and factories.
Owner Reviews
Practice shows that the use of such radiators in autonomous heating systems reduces consumption by 50% for solid fuel boilers and 2.5-3 times for electric ones. This type of appliance has well replaced the old cast-iron radiators, allowing you to save energy very effectively. All user reviews testify to the high degree of efficiency of vacuum radiators in comparison with traditional options.
Varieties
At the moment, there are already electric vacuum heating radiators. The principle of their operation is that the flow pipe was replaced with an electric heater, supplementedthermostat.
Vacuum radiators have advantages and disadvantages, as already mentioned. It is important to note that if you need to quickly heat the room, they have no equal, but if you need to raise or lower the temperature, then cast-iron batteries will do much better.
Conclusions
As a result, we can say that it is worth installing vacuum lithium bromide radiators in apartments that use heating meters. This option is also good for autonomous heating systems. This is a suitable option for those cases where the boilers do not give too high a temperature, since a small indicator is required to start the reaction.
