DIY infrared heater

Heating in the houses is turned on in late autumn, and it, unfortunately, turns off in the early spring, when low temperatures still stand outside the window. As a result, the apartments are cold, and the heat quickly leaves through the cracks in the windows. How to be in this situation?

Fortunately, there is a way out, and it consists in using an infrared heater, which can be made independently, without having professional knowledge. And in the material below we will talk specifically about the hand-made manufacturing of a heating device.

Features of self-manufacturing

Do-it-yourself infrared heater does not heat the air in the house compared to conventional appliances. In the process of operating such equipment, objects exposed to infrared rays are heated. And it is they who give off heat, and heat the air in the room.

Having decided to make a heating device with your own hands, it is necessary to take into account that its main elements are: a reflector (serves as a reflector) and a heating part (emitter).

Attention! To check the effect of the reflector, you need to take food foil, and hold it near your hand for 1-2 minutes. After this time, you should feel the heat, which will indicate the effective work of the part.

And also an integral part of the purchased devices is the controller, through which the necessary degree of heating of the emitter is established. In self-made installations, it may not be, but then it will not be possible to establish optimal temperatures.

But the main feature of self-made devices is their affordable cost. In fact, the user does not need to purchase expensive parts, since most of the components can be found in the garage, on the mezzanine and in the tool box.

There are three ways to make a heater at home, and now it's time to talk about them in more detail.

Glass and foil heater

How to make a do-it-yourself infrared heater? In addition to two identical pieces of glass and aluminum foil, you will need to prepare:

  • Paraffin candle;
  • Sealant;
  • Wire with plug;
  • Epoxy adhesive;
  • Clean napkin.

At the first stage, we clean the glass, and after that we move them exclusively on one side above the lit candle. You should get evenly smoked glass. They will become a conductor.

Important! In order for the soot to lie evenly, it is recommended to cool the glass a little before starting work.

Then we take a cotton swab and make a transparent frame around the glass perimeter, the width of which will not exceed 5 mm. From the foil we form 2 rectangles with a width equal to the width of the conductor layer. This foil act as an electrode.

At the next stage, the glass plate is placed smoked upside down, and copiously coated with epoxy glue. A foil is placed at the edges. At the same time, its ends should slightly extend beyond the boundaries of the glass.

The resulting structure is covered with the second half of the glass, smoked side down, and then seal the perimeter of the resulting component. After that, the resistance measurement of the conductor follows, and based on the data obtained, the power is calculated using the formula: N = R x I2, where N is the power (W); R is the resistance (Ohm); I is the current strength (A).

If the power indicator is satisfactory, we connect the device to the network and enjoy the optimal temperature in the apartment. In other cases, you will need to disassemble the device again and look for where the error was made.

The device from the old reflector

To get started, we need a nichrome thread, a reflector originally from the USSR, a steel rod and a refractory dielectric. Initially, we clean the reflector from contamination, and inspect the integrity of its elements. Then measure the length of the spiral on the cone.

After that, a steel rod is taken, on which a nichrome thread is wound with a step of 2 mm. At the end of this procedure, the resulting spiral is removed and laid on the dielectric. A current is connected at both ends.

As soon as the coil heats up, the voltage must be disconnected and placed in the groove of the heater cone. Then we connect it to the power terminals and begin to use a heater made by ourselves.

Laminated Heater

To make a heater, take:

  • 2 sheets of multilayer plastic 1x2 m;
  • Graphite powder;
  • Epoxy adhesive;
  • Wood frame;
  • Plug for sockets.

Initially, we make a solution, which includes graphite powder and glue 1 to 1. Then we apply it to the plastic in a zigzag manner from the rough side. This treatment will act as a conductor with high resistance.

After gluing two sheets of plastic with the sides where the prepared solution has already been applied. The fabricated structure is placed in a frame, and then terminals are connected to it on both sides. After the solution has completely dried, the wiring pops up to the terminals and the device is ready for connection to the network.
