Device and principle of operation

DIY electrode boiler

A homemade boiling pot with two blades screwed to matches is a familiar object. The electrolysis process forms the basis of the electrode boiler’s same mode of operation. Because it contains salts of various metals, ordinary water is a conductor. When metal contacts submerged in water are subjected to a direct current, the charged salt particles, or ions, start to migrate and accumulate on the contacts. Ions in our network will change their direction of motion 50 times per second when the current is alternating at a frequency of 50 Hz.

The amount of salts in the water passing through the electrode boiler increases the intensity of particle movement and decreases the liquid’s resistance. Ohm’s law states that an increase in current results from a decrease in resistance at constant voltage. Water heats up quickly because it conducts electricity less efficiently than metals like copper or aluminum. Electrode heating boilers accomplish this by turning nearly all electricity into heat. The concentration of salts in the coolant determines the strength of the current and then the heater’s power:

P is equal to UI, where:

  • P – power value, W;
  • U – voltage in the network, for a single-phase network is equal to 220 V, for three-phase – 380 V;
  • I – current strength, A.

The electrode heating boiler that is typically used by manufacturers has a cylindrical body composed of a pipe segment with a round electrode inside. The phase wire is led to it as the initial point of contact. The housing itself serves as the second contact, and the neutral wire is attached to it. The device’s body must ground in order to prevent electrocution, and a third contact is provided for this purpose. The artisans utilize the identical blueprint to create electrode boilers by hand.

The order of works on manufacturing of the heater

The homemade electrode boiler drawing must first be studied; it shows a design that calls for the least amount of welding.

1 – Ø57 mm seamless iron pipe with internal thread; 2 – paint coating resistant to heat; 3 – Ø32 mm externally threaded inlet and outlet sockets for heating medium; 4-metal plugs on the side; Five: Ø25 mm internal electrode for boiler; Six: M6 threaded connection terminals for grounding and neutral wire; Eight: rubber or paronite gaskets.

If you have the skills of a welder and the appropriate equipment, you can change the design by welding instead of threaded plugs circles of metal. Some craftsmen make an electrode water heater with the coolant outlet upwards by installing a spigot instead of a plug. The inner electrode will need to be insulated from the housing, for this purpose you can use different fluoroplastic bushings or make the plug itself from fiberglass plate. That and good electrode heating boilers, made with their own hands, that there is a wide scope for improvements and modernization with the use of improvised materials. Only do not get carried away and make the device from different metals, they can form a galvanic pair, as a result on one of the electrodes will actively grow scale.

Yes, of course! The article’s central thesis is as follows: We’ll walk you through building your own electrode boiler in this guide so you can heat your house. You can build an economical and environmentally friendly heating system with easy-to-find materials and simple instructions. We’ll guide you through every step of the procedure, from comprehending the fundamental ideas behind electrode boilers to putting the parts together and making sure safety precautions are taken.

Assembly instructions

Once you have a basic understanding of how to construct an electrode boiler by hand, you can move on to part preparation and assembly by following these instructions:

  • Mark and cut pipes for the body and spigots, in them with the help of a bolgar to make spherical-shaped selections to fit the cylindrical surface of the body. Drill holes in it where the spigots are to be welded.
  • All threads can be cut using special taps and dies for pipe threads. If there are no such devices, it is necessary to turn to a lathe shop. You can also mill plugs, fluoroplastic sleeve and inner electrode at the same place.
  • Weld the ready-made spigots and terminals for connecting the wires to the housing.
  • Fix the electrode in the plug and install it in a homemade electrode boiler. Screw and tighten both plugs.
  • The finished product can be painted with enamel resistant to temperatures up to 120 ºC.

It is essential to check the permeability of the welds after assembly. It is insufficient to just fill the unit with water because the system can have an operating pressure of up to 2 bar and an emergency pressure of up to 3 bar. Slag should be removed from the seams and soap foam should be applied. Subsequently, use a compressor to inflate the body to a point where bubbles form in the non-welding areas. Following the completion of the check, the DIY electrode heating boiler can be installed in the furnace room and linked to the system by following this plan:

1. The electrical installation for the heating system; 2. The safety group, which includes a pressure gauge, air ejector, and safety valve; 3. The ball valve; 4. The heating appliances; 5. The expansion tank; 6. The emptying tap; 7. The strainer; 8. The pump.

Putting the heater into operation

The final steps include setting up the electrode boiler, adding water to the system, and connecting the power and ground wires. It will require changing the coolant’s composition in order to operate at peak efficiency. Typically, tap water is utilized; however, it contains several harmful inclusions that cause scale to form on the electrode surfaces. If distilled water cannot be obtained, then tap or rainwater should be used to initially fill the system.

Such tools and supplies are necessary for adjustment:

  • Current clamps or ammeter;
  • soda;
  • syringe;
  • stirring vessel.

Since the manually constructed electrode boilers in the above drawing will have a power of about 4 kW, the computation indicates that the circuit’s current should be 4000 W / 220 V = 18 A. To heat the water in the system, the ammeter is first connected to the power supply wires and then plugged into the network. At this point, a soda solution is created in the container, roughly 1/10 of the total. It is preferable to add it to the system using a syringe at an open expansion tank or another location.

After switching on, the first reading of the ammeter will be less than 18 A. Small portions, without hurry, a solution of soda is added to the coolant for electrode boilers. At the same time, the system must be fully heated. If distilled water was poured, the process will take a long time, you need to be patient. Addition should be stopped when the device shows 16-17 A, otherwise the concentration can be exceeded. This is fraught with boiling and steam ejection or rupture of plastic pipes.
