5 ideas build improvised electric heater

idea №1 - Compact model for local heating

easiest way, which will make the electric heater is exactly this.To begin, prepare the following materials:

• 2 identical rectangular glass, an area of ​​about 25 cm2 each (for example, the size of 4 * 6 cm);
• piece of aluminum foil whose width is no more glasses width;
• cable to connect the electric heater (copper, two-wire, with plug);
• paraffin candle;
• epoxy adhesive;
• sharp scissors;
• pliers;
• wooden bar;
• sealant;
• several ear sticks;
• clean cloth.

As you can see, the materials to build a home-made electric heater is not scarce, and most importantly - all may be at hand.So, make a small electric heater with your hands can be according to the following steps below:

1. Carefully wipe the glass with a cloth from dirt and dust.
2. pliers, gently grab the edge of the glass and fire one side of the candle.Soot must uniformly cover the entire surface.Similarly, you need to burn and one side of the second glass.To better soot deposited on the surface, it is recommended to assemble the electric heater to cool the glass.
3. After the glass blanks cool, carefully using a clean ear sticks edge no more than 5 mm around the perimeter.
4. Cut two strips of foil, width corresponds exactly to the area of ​​the sooty glass width.
5. Apply glue to the glass across the burnt surface (it is conductive).
6. Place the pieces of foil, as shown in the photo below.Then apply glue to the other half and connect them.
7. then seal all joints.
8. With a tester, measure the resistance of your own home-made heater.Then calculate its power, using the formula: P = I2 * R.To learn how to use a multimeter, we are told in the corresponding article.If the power does not exceed the permissible values, go to the end of the assembly.If the power is too large, it is necessary to alter the heating element - to make a thicker layer of soot (resistance becomes smaller).
9. Glue the ends of the foil to one side.
10. Make a stand from the bar, setting her pads connected to the electrical cord.

Here on this technology can be made small electric heater with your hands.The maximum heating temperature is around 40 °, which would be sufficient for the local heating.However, this homemade for room heating will, of course, a little, so below we provide better options for home-made electric heaters.

idea №2 - Mini-heater from banks

Another original model improvised electric heater that is suitable for local heating in the garage or room.All you need to build it:

• Bank out of coffee;
• transformer 220/12 V;
• diode bridge;
• cooler;
• Nichrome wire;
• PCB, an area roughly the diameter of the banks;
• drill with a thin drill bit;
• soldering;
• cord for connection to the network;
• pushbutton switch.

This statement is even easier and make the electric heater out of the jar with your hands can be 1-2 hours.To start with the PCB need to remove the foil and cut in the middle of it, as shown in the photo below:

Then, using a drill hole must be made on the diagonal.By the way, this can be done and make a homemade mini drill according to our instructions.The anchoring holes Nichrome wire, then solder the wires.

combined in one circuit transformer, diode bridge cooler, Nichrome wire and switch.

Mount the fan into the jar, using glue, and then fasten the PCB as shown in the photo:

placed in a jar all the elements of an improvised electric heater, drill in the lid holes and check the efficiency of the device!

If you want to make a more powerful device with spiral, we recommend to view video tutorial below:

idea №3 - Cost-effective infrared device

So we turn toElectric heaters, more powerful, which you can easily make yourself at home.For the production of infrared heater, we will need the following materials:

• 2 sheets of plastic, each area of ​​1 m2;
• graphite powder, ground to a flour fraction;
• epoxy adhesive;
• two copper terminals;
• cord with plug for connection to 220 volts.

So make room infrared heater with your hands can be according to the following instructions:

1. Mix graphite epoxy glue in the ratio of 1 to 1.
   
   
2. Apply ready-conductive mixture on one side of the plastic zigzag asIt is shown in the diagram:
3. glue the second sheet on top and wait until the glue dries.
4. Attach both sides of the electric heater terminals.
5. Connect the power cord to the terminals and proceed to checkout homemade.

By the way, in order to design was stronger, it is recommended to put the infrared heater in a wooden frame, which can also be done by hand.Do not forget to check before connecting the device to calculate the resistance and power!

idea №4 - Oil device

Another model of the device, which is recommended to collect for heating garages or other outbuildings in the country.All that you need - the old battery, tubular heater, butter and jam.You will also need welding machine, welding skills and some spare time.The photo below shows one of the options of self-made oil heater.

bottom left installed a tubular heater at the top drain plug / oil inlet.Simple design electric heater, which is enough to heat a small room.

idea №5 - Automotive electric

Well, the latest version of a homemade heater - a device operating on 12 volts, which can be used to heat the interior of their own cars.For assembly you will need the following materials:

• old power supply from your computer;
• Nichrome wire;
• remnants of floor tiles;
• fasteners: bolts, angles, plates.

himself to make an electric heater for the car is not so difficult.The assembly process is recommended to view the master class in the photo examples:

disadvantage of this heater - the increased risk of fire in the car, becauseNichrome wire is practically not protected.In addition, you need to properly calculate the power of the device, so as not to damage the car wiring.

's all ideas on assembling improvised electric heater.As you can see, a simple electrical device can be easily manufactured from a variety of materials at hand, it would wish.If you like workshops, share the recording with your friends, so that they know how to make their own hands a heater for the home, garage or car!
