Steam generator heater: feedback from owners. Steam-heater by own hands: drawings, device, principle of operation

Steam generator heater, which you will surely find interesting to read before purchasing equipment, is a modern heat-exchange unit that is very different from the known heaters. The principle of its functioning is that there is water in the system, which is heated by means of electricity. The water circuit is completely closed at the same time. This allowed us to create a fairly simple but very effective heat transfer scheme.

general description

The steam-heater, which you can read about below, is essentially a thermal battery that concentrates the heat transfer fluid with a high temperature. Even if the electricity is turned off, the coolant will begin to produce heat for some time. This is the main distinguishing feature of the described type of heater from other electrical analogs, which cool down after being disconnected from the AC mains. Steam-heater has internal coolant, the temperature of which can vary from 90 to 120 degrees. These modern devices have high-precision automatic units, through which it is possible to correct the temperature regime and operation of the apparatus. Automatics can be controlled quite simply, the user will be able to understand it independently.

Owner feedback

Steam generator heater, feedback about which will help you decide the choice, has many advantages. According to buyers, such devices are characterized by a long service life, which is set within 30 years according to the manufacturer's calculations. This quality is due to the fact that inside the metal enclosed structure, where there is liquid heat carrier and vapor, there is no air. All this indicates that the processes of corrosion of metals do not occur.

Among other things, this container can not explode, since there is a certain amount of water in it that does not fill the tank completely. Steam generator heater, the reviews of which will be interesting to read to any consumer, has another advantage, which is expressed in the absence of the probability of a device breaking when the heating system is switched off. Thus the electric heater can freeze, but it will not lead to negative consequences. According to buyers, this is due to a small amount of water inside, which can freeze when the temperature drops, and when the device is turned on again it becomes defrosted. After the water continues to circulate in a predetermined cycle.

Steam generator heater, reviews about which are often only positive, allows you to adjust and adjust the temperature in each room at the discretion of the owners. In each room, you need to install the device, which saves energy consumption. Customers choose this equipment also for the reason that it can be used in premises of a very different purpose. Most often they act as an additional heating system. If we are talking about buildings of small dimensions, the steam-heater can be used as a basic heating.

Home masters also like the fact that installing this device yourself is quite simple. Traditionally it is located under the window opening, although this is not the only option.

Device construction

Factory steam-heater are somewhat like tubular radiators, which are very close in size. The tubular structure is used for the reason that it has a shape in which the heat output is as efficient as possible. Through the tube, the coolant moves from the hot zone to the heat transfer region more easily. The device has a shape that resembles a conventional radiator made of pipes. This indicates a greater likelihood of making such a device with their own hands. The system has an electric water heater, which consists of a body based on a heat-insulating material. This part is provided with a thermally conductive top cover, in which there are U-shaped heating elements with conductive terminals.

Principle of operation

Steam-heater, the principle of operation of which should be known to you, if you are going to manufacture it yourself, functions by converting electrical energy in a closed cyclic space. Ultimately, the thermal energy is obtained by heating a limited amount of water. After it turns into steam, what happens in the hermetic cavity of the heating compartment. Steam condenses, gives off heat, and water flows down inclined inner surfaces, entering the heating element. In this part, the liquid is again converted to steam. In general, it can be noted that such non-tertiary heating systems are the estimated number of vapor-drop heaters distributed over the area of the premises. At the same time, the heating composition of the equipment is integrated into one electrical network, the operation of which is electronically controlled.

Preparation for work

In order to make a steam-heater, it is necessary to initially prepare some materials and tools, including a lid, stainless wire, a copper pipe, and a valve.

Nuances of works

A lid is installed on the metal pipe, to which a pipe of a not too large diameter is fixed. On the other hand, it is necessary to exclude air ingress. As a result, a design should be obtained that allows to regulate heat generation. The device can use not only water, but also other liquids as a low-boiling oil, as a heat agent.

The master must create a vapor-condensate sealed enclosure that is mounted on the support posts. You must create a heating chamber with a liquid inside which the body of the electric heating element with conductive terminals is installed. They should be fixed to the end wall of the housing, the heating chamber should be located at an angle to the horizon, so that the heating element is located in the chamber below the level of the surface of the heat agent.

Making a device yourself

Steam-heater with own hands (its drawings are presented in the article) can also be manufactured. The body of the home-made unit will consist of a pipe that is made of stainless steel, aluminum or copper. Filling the metal pipe is through the cover, which is fixed by a pipe of small diameter. The second end of this pipe must be tightly closed. A filling valve is installed on the filling pipe, which is necessary for gas analysis. These manipulations the owner of the dwelling carries out after resource tests.

Making a wick

When choosing a wick, it must be taken into account that the material in its base must be compatible with the working fluid. When a vapor-heater heater is made by hand, it should be provided with a wick. The wick is most often used as a woven wire mesh. This element can be braided from monel, copper or stainless wire. To make the wick is not recommended to use aluminum mesh, because it is difficult enough to weave.

Specialists recommend using a stainless steel mesh for making. The connection between the elements should be carried out by diffusion welding. This will allow to form a sufficiently strong solid wick, which is connected to the walls of the body of the metal pipe. The master should perform diffusion welding at a temperature of 1150 degrees in a vacuum oven. It is not always possible to create such conditions in everyday life, that's why if you decided to make a steam-heater by yourself, then the execution of several elements should be entrusted to specialists. The wick can be made of felt, as well as foam-like material. Metal and ceramic felt can be found on the market.

Conclusion

You should definitely study the device of the steam-heater, if you plan to manufacture it. This will make it clear that the slope of the heating chamber should be at an angle of 20 degrees, but not more. Its position should be such that it is facing towards the end wall of the body. This effect can be achieved if the support racks do different heights. They should be located at different ends of the body. Steam-heater, the feedback of owners about which were presented above, should have an electric heating element, fixation of which is made with the help of gaskets, union or union nut and nipple.
