How to make the boiler with his hands?

The water is heated for a long time does not require any tricks, thanks to excess heating appliances as electric kettles, boilers, coffee machines, and other devices. But there are situations when they are not at hand, and boil or warm up water should be right now. In this case, you can raise the boiler with his hands from suitable for this improvised.

Safety warnings.

Set out in Article methods for someone to become a nostalgia for the student's age or military service. But it should be clearly understood that such improvised devices are a potential threat from the point of view of electric shock, and from the point of view of fire and explosion. Therefore, their actual use as possible should be minimized, and the continuous operation to replace the factory units. Next, we consider the simplest options that can even assemble an aspiring electrician without any skills or knowledge.

Kettle of razor blades

This option has already become a classic for the people who lived in the period of the national deficit. Over the years, there was plenty of variations of these heating appliances and a decent experience in their implementation, so consider this model in more detail. The blades are not the only one for the boiler electrodes, but they are used most frequently and it is caused by several important reason:

• High quality steel - the electrolysis, the water column flowing an electric current generated by electrons of the metal is isolated from the electrodes. Because of the resistance of a liquid, not all the particles pass from one electrode to another, and precipitate as metal is significantly altering the taste of water. Razor blades are made fairly high quality, so the percentage of sludge from such a boiler will be minimal.
• The optimum ratio of geometric and physical parameters - despite the fact that no one blade invented as an electrode under the heater, they provide a relatively high heating rate liquid.
• Mass distribution - can be found in virtually every home, garage or workshop, because of which are constantly at hand.

Materials for the boiler of the blades

Before the production, you need to get these elements:

• The blades themselves - for quality work of the boiler does not matter firm and status of cutting surfaces, you can even take a blunt blade. It is important that they be of the same design, it is best if you take them out of one package.
• Dielectric insulation for one blade in the boiler on the other - it is possible to use any available to you items (plastic caps, plugs). If nothing comes to mind, it is best to isolate heating elements apart use regular matches.
• Material for fixing the electrodes in the boiler - the most commonly used strings. Definitely not worth the bonding glue, and even more so, it is not necessary to resort to the wire and other metal products - they'll short circuit blades.
• The power cord with plug - you can use any version with stranded copper conductors, which will be convenient to fasten around the blade.

This is the minimum, you may want to complicate the design using crocodiles to connect wires to the blades or installing plastic block as a base.

The procedure of manufacturing

To get the boiler of the blades, it is desirable to have on hand, such tools: pliers, knife or side cutters, electrical tape. The manufacturing process is as follows:

• strip the wires on the power cord with mains plug, you will need about 2 - 3 cm of bare conductors;

  

• Fasten each end of the wire to the blade, note, do not try to solder - it's useless, you need to tightly fasten the wire, if it is impossible to manually take the pliers;

  

• lock the blade at a distance from each other by a dielectric, in this case matches are used;

  

• Wrap the water heater resulting thread, so that it did not break up during operation, if it holds true, can do without the thread.

  

Homemade heater ready, it should be noted that the distance between the blades and the parameter determines the power consumed from the network, and the heating rate. Therefore, the most rapid heating you get at a distance of 2 -3mm (matches in thickness) at a distance of 2 - 3 cm in proportion to the heating time increases.

But the amount of electricity consumed for boiling water, for example, in a half-liter jar, will be the same for both cases.

Do not forget that all home-made boilers, electric current is passed through a heated the liquid can not be immersed in a metal container, they will be under potential and can hit shock. Suitable only utensils made of dielectric material - glass, polymer and others.

Of PETN kettle

Also, the heater can be collected from unnecessary electric kettle, provided that the heating defective heating element. In this case, nothing more to invent not necessary - you need self tan and cord with plug. First check the integrity of both items of electrical apparatus with a multimeter.

Rung cord and heating element, if they are correct, it means that they can be safely used in the manufacture of the boiler.

To connect the pins PETN is more convenient to use screw terminals, but if there are not at hand, you can use a conventional soldering iron.

For the manufacture of the boiler, perform the following sequence of actions:

• disassemble the kettle and take out the heater, do the same procedure with the stand and remove the cord from it if the cable is long enough, you can simply cut it at the base.
• using a knife or pliers to remove the insulation from the wire edges;
• fix the screw terminals on the heating element contacts with a screwdriver;
• on the other hand to terminals Connect the stripped wire cord;

  

• check multimeter reboiler circuit and the resistance between the plug and the housing.

Kettle is ready, it can be used for heating service water and drinking for boiling. By its parameters work, he is no different from the classic kettle or boiler, so it can be used in metal containers. Due to the fact that the heating device is used PETN factory, you get quite a powerful boiler.

of nails

For this you need a boiler 6 nails in length of 8 cm, thick piece of wood, about 2cm, which can be installed on the edge of the capacity of non-conductive material, the finished cord or wire pair with fork. To work you need pliers and a drill with a drill of the same diameter as the nails.

The principle of the creation of the boiler is as follows:

• drill a hole in the board at a distance of 5 mm from each other;
• insert nails into the holes, leaving free distance above the board in 2 - 3 cm, it was convenient to wind the wire;

  

• zachistte cable edge 5 - 10 cm with a knife or wire cutters, you must remain bare metal without varnish and other insulation;
• screw loose strands to the nails for the most caps - 3 nails for each of the wires, note that the reliability of electrical connections depends on the density fit, so they need to be tightened as much as possible stronger;
• hammer nails to lock pliers, but be careful not to weaken the mechanical effect electrical contact location.

Boiler ready, pour water into a glass jar or plastic bowl, set top bar so that the sharp edges of nails immersed in water. Turn on the heater in the network and wait for boiling. Not on your nelly not attempt to check the temperature of hot water with a finger or a hand, because when the boiler you will get an electric shock.

of the spoons

For this boiler, you will need two metal spoons, two or three-wire cable, plug, glass jar and two pegs. The manufacturing process of the boiler consists of the following stages:

• remove the insulation from the cable and wires to get loose strands of 2 - 3 cm on each side;

  

• attach one end of the cable plug, and concluded the other end, attach the spoon;
• place the spoon in a glass jar with opposite sides and lock pegs, spoons thus should not be in contact;

  

• fix the cable on the outside of the banks by means of an adhesive tape.

  

Kettle ready - enough to pour water in the jar and insert the plug into the socket. Note that moving the bank enabled device is not safe, so pre disconnect the boiler from the mains.

Kettle 12 Volt

Claimed device for many automobile owners allowing heated water away from civilization, using power from a car battery. The most difficult is the selection of the heating element, which is calculated according to the formula: P = U²/ R

where P - power of the boiler;

U - nominal supply voltage;

R - resistance of the circuit.

For example, when the impedance circuit 1 ohm reboiler power feeding source 12B, 144Vt amount. Accordingly, the nozzle heating time be about 10 - 15 minutes.

As the heating element can act ceramic resistors or nichrome filament wound on the PCB. Connect them to the two battery terminals and the boiler is ready. The main condition - the capacity of the heating must be of a dielectric material.
