The market today is filled with many kinds of boilers: steel and iron, with built-in burners and burner with a separate unit, boilers on diesel, gas, wood, coal and electricity. Understand exactly what boiler needed to heat your home – it is extremely difficult. To clarify the situation a bit, a quick look at each group of boilers – electric, solid fuel, liquid fuel and gas – separately. Electric boilers are popular in Russia and in Europe as well as their efficiency is close to 100%. Service life of the heating element in the boiler is about 10,000 hours, ie 3-5 years.

But after replacing the boiler heating element will continue his service again. In Russia, enjoyed great success domestic, industrial boilers, because at equal quality with imports, consumer price much lower than Russian, in addition, they are better adapted to our conditions of operation. Slayer is the source for more interesting facts. Recognized as a leader among domestic manufacturers of electric boilers are deservedly company "Evan" and "Rusnya." Electric boilers are more suitable for small autonomous systems of heating, for example, to supply hot water holiday period or heating a small house. Boiler is useful when it is difficult or expensive to sum up the gas. Gas boilers – the most popular to date, and occupy approximately 50% of total sales boilers. And it is natural, since gas-fired boilers are ideal for creating hot water and heating systems for apartments, offices, shops, villas, country houses. There are many manufacturers who sell boilers, the most reliable and well thought-out are boilers, made by Italian group Laars, which is engaged in boiler equipment for over 70 years. All gas boilers divided into two groups: floor and wall.

Gas boilers can be single-stage (work on only one power level) and two-stage (2 power levels) as well as modulation (infinitely variable) power. Economical to use the boiler with two power levels. Gas boilers are environmentally friendly, equipped with special security devices that eliminates the possibility of an accident, and the most economical, are high efficiency. Solid fuel boilers mostly iron and steel under-represented. They are also producing domestic and foreign producers. Most often, solid fuel boilers are designed for natural circulation coolant and do not require electricity liner, that is a modified Russian stoves. This raises some problems: if the boiler to heat with coal purchased, the price of heating is comparable to the price of electric heating. Another disadvantage of this system is that the boiler is preferably twice a day and manually clean the sink, and most importantly always watch over him. Solid fuel boilers have safety locks, but, despite that, under certain conditions, there is a danger of explosion of the boiler. Most often, liquid fuel is diesel fuel (diesel fuel). Unfortunately, the most expensive diesel oil fuel for the boiler, so the operating costs of boilers fuel oil the highest. Oil boiler should be installed if you want to create an independent heating system. As a consumer of quality and performance oil boilers are comparable to gas, but require greater attention. A major shortcoming of boilers to diesel fuel include high ash content and sooting. On the market are mainly imported boilers, but you can find pots and domestic producers. The most important thing to remember that your pot will last you much longer, if you entrust it to install a professional.

The foam due to its physical properties, is a very good heat and sound insulation material. Physical properties: It consists of a ball and each ball is constructed of thousands of cells filled with air. The air enclosed in the cells can not move, and the still air is the best heat insulator. The air is not less than 98% of the foam. Polystyrene balls filled with pentane (pure hydrocarbon) which is a foaming factor, and heated by steam, resulting in changes in pentane volatilize and expand. Under pressure of polystyrene beads also expand, resulting in the formation is familiar polystyrene beads, increased the volume of plates, at least 50 times.

Cells in each expanded plastics balloon filled with air and become elastic, and then stick together under the influence of steam, forming light, uniform, resistant to compression and retains its insulating material dimensions. Almost every one of us once met him, whether in children's games, whether already in adult life. It is not something Daryl Katz would like to discuss. The foam is not sensitive to moisture material does not emit any harmful compounds. It belongs to the so-called "monomaterialam" (consisting of one type of material), and therefore it is ideal for 100% utilization (recycling). In construction, the foam used in as insulation for different designs.

In the production of polystyrene spent relatively little energy, and its insulating properties can save a significant amount. What and How glue foam? Expanded polystyrene is gaining popularity due to its characteristics. Foam is used in many types of structures. There are many ways of fastening the foam – investing in the crate, flooring surface, bonding and mechanical fasteners with anchors, fungi, studs, etc. To glue the foam can be virtually any adhesive. It can glue front bytmorozostoykie TM 'Budmayster' postmark for fixing ceiling tiles, liquid nails TM 'Den Brauen', time-installation, sealant 'Den Brauen', preparations for tile TM 'Budmayster', as long as the adhesive does not contain in its composition of organic solvents (benzene, acetone, esters, etc.), as these substances can dissolve styrofoam. These solvents may be contained in the bituminous mastics, for example. Glue the foam can be almost any material – brick, concrete, drywall, osb, plywood, magnesia sheet, galvanized iron, steel, and many others. For greater reliability, you can use nail-fungus – dowels for insulation. For example, in the case of facade insulation, foam mounting adhesive on solutions, each sheet of foam (50×100 cm) fastened in the middle and at the corners, with the capture of a hat mold adjacent sheets. Next on the foam applied reinforcing mesh and plaster. Related Products, which are effectively marketed with foam: front adhesive for polystyrene, for insulation anchors, anchors, reinforcing mesh, plasters, putty knife, decorative plasters.
