Film floor heaters have obvious advantages over cable heaters:

1. Installation of a film heat-insulated floor is carried out in just a few hours.

2. There is no need to open the floor.

3. There is no need to make a screed.

4. The film heater can be installed under any coating: laminate, parquet, linoleum.

We examine the system of film insulation material for the floor. Its central thickness is approximately half a millimeter. A similar heater is made from glued dacron films. Between these films are conductors (silver or copper), and a heating graphite element ...

Hybrid cars are becoming increasingly popular all over the world. This is caused not only by their fuel efficiency, but also by environmental requirements, which are constantly being tightened, and hybrid cars reduce emissions of unburned hydrocarbons and nitrogen oxides into the atmosphere by 85%.

Most hybrids currently have two engines. This is an internal combustion engine (hereinafter ICE) and an electric motor. An electric motor, as a rule, has less power than an internal combustion engine, but still, it requires heavy batteries or fuel cells to operate. They take up a lot of space in the car and increase its weight. For example, Toyota Prius II, which is considered one of the best hybrids ...

A detailed description of the selection and installation of an electric water heater in the apartment

Disruptions in the supply of hot water to our apartments and houses often occur, and in some cities and regions it is simply regular and this causes great inconvenience to many families.

If the house has small children, then the lack of hot water from a small temporary inconvenience turns into a real problem. However, solving this problem is quite simple and not even too expensive by installing an electric water heater. To begin with, we will determine what principle of action needs a flow or storage heater. Instantaneous electric water heater costs less ...

The modern elemental base of electronics allows you to create devices simple in circuitry, but having a fairly wide range of functions. Previously, such devices were only available for use in complex and expensive professional systems, and now their use makes our everyday life more comfortable and easier.

This article will talk about devices that use sensors that respond to infrared radiation. Once such sensors were mainly used in security systems, now no one is surprised by the doors that open in front of each incoming person or the automatic inclusion of lighting in the entrance. And all these are infrared sensors! ...

This is my first article, I am just starting, so please do not judge strictly.In this article, I will share my personal experience and tell you how to conduct light on a glazed balcony. Simply, if it is not glazed, then why is there light?

When there is a window frame on the balcony, there are plans to sheathe the walls with a rail, to insulate the floor, light in this room is simply necessary.

So, you need to hold the light on the balcony. Where to begin? With an assessment of the situation. From which the bulb will be powered by electricity.

If the house is old, then all the wiring is in the ceiling plate and only there, look for the power cable and pull it from the balcony.As a rule, all ceiling twists, it is better not to touch, but for good, change the wiring completely in the whole apartment to copper. What to do? And let's eat from a regular outlet! Is there such a thing? Still not far from the balcony? Here is the solution! ...

Starting January 1, 2011, the household appliances we purchase must have a class designation of energy efficiency. That is, in the passport of the device or on the case, there must be a label of a certain color, with a letter indicating the class of energy efficiency.

The letter A, on a bright green background, marks the equipment with the highest energy efficiency indicator. Marking B, means lower energy efficiency and is shown on a light green background.

The letters C, D, F, G follow and the color scheme changes from green to yellow (D) to bright red (G), showing the lowest energy efficiency. Additional classes also exist. A +, A ++, these are devices whose energy efficiency is higher than that of class A...

The corridor switch is very familiar to older electricians. Now such a device is somewhat forgotten, so you have to briefly talk about the algorithm of its action.

Imagine that you leave a room in a corridor in which there are no windows. Click the switch near the door, and the light in the corridor lights up. This switch is conventionally called the first.

Having reached the opposite end of the corridor, before exiting to the street, you turn off the lights by the second switch located near the exit door. If someone else remains in the room, then he can also turn on the light with the first switch when exiting, and turn off with the help of the second. When you enter the corridor from the street, the light turns on with the second switch, and already in the room turns off the first ...

Surely you know the Veterok heater. By the way, “Veterok” is not a name, but the principle of operation of this device. Like oil or spiral electric heaters (calorifiers), Veterok has a higher efficiency.

An indisputable plus, when using this device, is, of course, its speed. After turning on the heater, it instantly begins to warm the air.

Why is the "Breeze"? The principle of action speaks for itself. A heating element (spiral), a fan, a regulator of heating levels, and a power regulator are mounted in a plastic case with holes for air diffusion.
