How to protect icing roof

The accumulation of snow and ice on the roof of the house negatively affects the roof - the load on the roof frame increases and its service life is reduced.

As practice shows, almost all spring drops from the ceiling of the room are not caused by damage to the integrity of the roof, but because of the snow, which formed an ice block on the roof.

In the modern world, this problem is solved very simply. It is necessary to provide the roof with a special anti-icing system. Installation of the anti-icing system should be done only in problem areas where ice is constantly appearing, creating a threat of damage to the roof or collapse of snow and ice ...

The article describes and experiences the use of various home-made and industrial mini-hydroelectric power stations.

Recently, due to the increase in electricity tariffs, renewable sources of almost free energy are becoming increasingly relevant.

From the well-known classical triad: solar panels, wind generators, hydro generators (HPS), the latter are the most complex. Firstly, they work in aggressive conditions, and secondly, they have maximum operating time for an equal period of time.

In the manufacture of a home-made hydrogenerator, you need to work harder and choose better materials to ensure its durability ...

LED lamp operating experience

We are living in an era of unbridled and unscrupulous growth of electric tariffs, and while Chubais’s thinking will dominate the economy, the situation will not change.

For example, we can recall that over 10 years, electricity tariffs have increased 20 times. Apparently, this is not the limit. The only way to counter, with the exception of theft, is to save energy.

Just a couple of years ago, everyone was hearing “energy-saving” lamps, i.e. conventional luminescent, only with an electronic starting and adjustment device and with the common base E14 and E27 ...

Cable heating: from underfloor heating to roofs without icicles.

Recently, cable electrical heating systems are finding wider application. The range of applications of such systems is becoming wider, their use is more economical, reliable and efficient. More recently, the scope of the heating cable was limited, perhaps, to the installation of underfloor heating.

Currently, the assortment of heating cables and even thermofilms has become much more extensive, which allows heating anything you want, from water pipes to roofs of buildings. But first, remember how it all began. The history of the development of the warm floor is rooted in the distant past and dates back several centuries, even if not millennia ...

Theory, practice, the current model of a wind generator and its industrial analogues with a description and price.

For those who often travels and stops for days and nights in nature, it probably occurred to me that it would be nice to have a recharge source for a car battery and batteries of other mobile devices: laptops, phones, gps navigators, lights, etc.

In addition, having a sufficiently powerful energy source of even 12 V, you can use a 12 - 220 V converter to get a full-fledged 220 V socket. This will further increase the level of comfort that all citizens are used to and increase the number of devices used to the usual level ...

Nowadays, people can not do without gadgets about which their parents did not even have an idea. Even when going on hikes and picnics, they take laptops, camcorders, gps navigators, televisions, music centers, etc. with them.

Electric sockets have not yet been integrated into the surrounding trees, and batteries have the ability to discharge. Therefore, renewable energy sources are becoming especially relevant. One of them is solar panels.

Choosing a home-made or industrial solar panel is a choice of cash expenses and a hobby. A man or woman whose hands are attached to the right place is quite capable of making a home-made solar battery in one two weeks ...

The appearance of infrared film underfloor heating in the services market is a clear example of how innovative technologies are becoming bolder in our lives, helping to create coziness and comfort in the house quickly and easily.

The fundamental difference and the main advantage of the infrared floor from other floors is the use of infrared radiation.

An ordinary warm floor, heating the air, creates convection currents in it, which rise up. As a result, you spend electricity to create a warm layer of air under the ceiling, and not in the part of the room where you are ...

The article talks about infrared heaters, which are an additional, and in some cases, the main source of heat to the room in the cold season.

The problem of insufficient heating of rooms by standard means of heating has always existed and remains relevant today, so new types and types of heaters are constantly being developed that can provide comfortable conditions for living and working.

Today, one of the best and most promising types of heaters is infrared. The most important advantage of infrared heaters over other types of heaters is their high safety ...
