Electrode boiler with his hands

electrode (another name - Ion) boiler is one of the electric heating appliances variations.It is used mainly in country houses and differs in that instead of the usual heaters equipped with a set of electrodes that, in fact, engaged in heated working fluid. Such innovations will get rid of the shortcomings of the electrical - low productivity and short service life.Due to the simplicity of the design, you can make electrode boiler with his hands .But before proceeding to the assembly, should be familiar with the peculiarities of his work.

Features

from the constructive point of view of a boiler - it is a small all-metal tube with polyamide coated (it fulfills isolator function).To the body are connected input and output of the coolant, and power terminals.On one side the tube is inserted into a set of isolated electrodes, while the other is hermetically sealed.

consider the technical parameters of the factory models.

1. length - up to 60 cm in diameter -. Not more than 32 cm
2. power can vary between 2 and 50 kW, in other words, the boilers can heat the room up to 1,500 square meters.
3. They can also be single and three phase.In the first case refers to low-power devices used in private homes, in the second - boilers with high efficiency targeting of industrial type.
4. optimum value of power consumption is achieved at a temperature of the working fluid in 75ᵒS.If the above figure, the energy consumption increases, and if it is lower, it correspondingly decreases (at sub-zero temperatures the thermal conductivity of the liquid component deteriorates).

As a method of supplying coolant ionic devices may be of two types:

• open systems characterized by the fact that the heated fluid moves in a natural way, transfers the heat and sent back to the heat source;
• in closed also has a special pump and expansion vessel - they are necessary for the initial phase of the working fluid warming.

On the merits

1. maindignity ion boiler is a high efficiency (up to 98%), due to the relative simplicity of the instrument.
2. small size allow you to use them even in small homes.
3. electrode boilers have no "dry run."Fluid is a full "party" of the working process, so its absence does not cause overheating of the system - only the circuit opened.
4. surges in this case are not afraid - if it is to fall, the unit is turned off, it just earns less power.
5. Economy - another advantage of electrode boilers.
6. Finally, they quickly reach the desired temperature and also cool down quickly, enabling automatic control effectively.

On the shortcomings

But there its disadvantages, among which:

• inability to work on emergency power supply systems;
• high requirements for coolant conduction;
• need for grounding because of the high risk of electric shock;
• need special knowledge to control the operation of the device.

Also note that the ingress of air into the body may lead to quite rapid corrosion.

manufacturing technology.Instructions

After getting acquainted with the boiler device can try to make a similar device in the home.This process is not as difficult as it may seem, but it requires the utmost caution and care.Otherwise the finished product could be unsafe.

Step 1: Prepare all necessary

to operate such equipment required:

• welding machine;
• electrodes;
• iron tee;
• electrode insulation (polyamide);
• neutral conductor;
• clutch;
• ground terminal;
• respective pipe sizes of steel;
• insulation terminals.

Note!At the preparatory stage, should examine the scheme of work of such equipment.

Step 2: Assembling the ion boiler

boiler first understand a few important aspects.Thus, the boiler must be grounded ion, as mentioned above, and even zero cable must be fed exclusively to the outer tube.It is also worth remembering that phase should be supplied only to the electrodes.

boiler With appropriate preparation of the assembly procedure should not cause any difficulties.

Step 1. Initially taken premix tube (optimal size - length 25 cm, diameter 8-10 cm).On one side the tube is placed in a set of electrodes mounted on the other coupling for connection to the heating pipe.

Note!To mount electrodes require a tee by which will be input / output coolant.

Step 2. Near electrode insulator set, which in addition to its direct function will simultaneously for added tightness of the boiler.

Step 3. for manufacturing the insulator used thermo plastic high quality.But the device is not only important for leaks, but also the possibility of a threaded connection of the electrode to a tee.It is therefore recommended to entrust the manufacture of the insulator experienced professionals who will make the item in accordance with the desired dimensions.

Step 4. welded to the body a large bolt.Next to the bolt is fastened zero cable and the ground terminals.

Note!For greater reliability, the second bolt can be attached, similar to the first.

Step 5. After connecting to the heating system (this is done with the help of the clutch) can only cover the finished pot by a decorative covering.This coating is necessary not only for the purpose of aesthetics, but for safety, protection against electric shock.Do not neglect this, t. To. It is necessary to limit access to the boiler.

Step 3: Installation works

At this stage the mandatory installation of such system elements:

• air vent;
• gauge;
• fuse.

This valves installed after the expansion tank.More detailed connectivity features to help familiarize the above scheme.

Other important points in the installation.

1. boiler is installed only vertically, which is due to the peculiarities of the operation only.Fasteners must be separate.
2. entire heating system thoroughly rinsed before installing the device.For this clean water is taken, diluted with appropriate means (such as eg Rothenberger).If a contaminated coolant or highway was poorly washed, the ion boiler performance will be significantly reduced.

   Means for washing

3. for grounding a copper cable ø4 mm can be used (or more) with a resistance not exceeding four ohms.The cable is connected to the plug-zero, which thus is located at the bottom of the unit housing.
4. Heating devices (batteries) are selected in accordance with the volume of the system.The best option - kilowatt power unit corresponds to 8 liters total volume.If you exceed this rate, the boiler will function longer than necessary, resulting in increase in electricity costs.
5. In addition, the regeneration of the heating system should be preferred bimetallic alloy or aluminum.Unacceptable use other alloys because they have a lot of different impurities that affect the conductivity of the working fluid.
6. If an open system is installed, the battery used should in any case have a polymer deposition on the inner surface, thus preventing the access of air and, consequently, will prevent corrosion.In a closed-type systems such there is no shortage.
7. From cast iron products should be avoided altogether, because impurities contained in them in large numbers, will reduce the performance of the ion boiler.Also, these batteries too much volume, which will increase power consumption.

about the used coolant

electrode boilers do not need specially prepared coolant, this mayIt is used in ordinary water (with the proviso that it does not exceed the resistivity of 1.3 ohm / cm).In this regard, the water still requires some training.So, if you simply pour distilled water, then no it will not bring success, t. To. It does not conduct electricity.

preparation process is to conduct experiments, as a result of which the resistance increases (using the baking soda, for instruments made of aluminum - ASO-1) or decreases (added to the melt or rain water).

In conclusion

Now you know what is the principle of the electrode boiler and how to assemble a similar machine at home and save a lot of money.The main work - strictly follow the instructions and comply with safety regulations.In this case, no problem.
