So you decided to come to pass on buying the water heater. It now remains to define in the selection Heater (columns). So, at what points should focus when choosing a water heater? How to choose water heater? 1.Vid ignition. By type of ignition gas water heaters can be divided into three types: with pezorozzhigom, with electric ignition and the ignition of hydro. The minus water heater pezorozzhigom include the fact that when disconnecting the column remains on ignition fuse (he subsequently provides the ignition of the burner). In columns with electric ignition inclusion is as you probably guessed from the spark obtained by electricity (batteries).
In water heaters with the ignition of hydro-electricity producing turbine, actuated water flow. 2.Moduliruyuschaya burner. When selecting and installing the water heater, please attention to this important element of both – modulating burner. Modulating burner will automatically adjust the height of the flame at different flow rates. This will maintain the desired temperature of heated water regardless of pressure fluctuations in the water that is not such a rarity. Need to pay attention to those who have the pressure of gas and water are not constant.
Especially it will be important at low gas pressure. Due to the fact that import speakers are tested at a gas pressure of 180-200 mm water column, but here it is, as a rule, below. As a result, the column can not issue a power referred to in the documents. Columns with modulating burners, natural more expensive, but in this case would be more reliable.
Private low-rise building on the monolithic housing construction differs slightly from his brother the giant multi-storey building. In the private sector and low-rise is not beneficial use of industrial technological methods, so building erected with the use of light concrete panel. After the end of this building serves as the casing and insulation. Technologically, the monolithic construction of houses concreting detail comes out in two stages. Constructing a special fence – the formwork, then it is placed rebar and pour concrete.
After that, wait until the concrete hardens, and the formwork is removed. Permanent formwork allows quickly get a pretty high-quality design, usually requiring no additional insulation of the building was built. This advanced technology allows you to build almost any houses – tiny cottages, small cottages, large houses and even flats (up to six – seven floors)! Furthermore, using permanent formwork can be built and public and non-residential buildings – office centers, restaurants, cafes, sports facilities and warehouses. Permanent formwork is composed of special units of polystyrene – very light (weighing 23 to 27 kg / cubic meter.) Hollow blocks, which can be installed by one person. The range of modules retained formwork for walls is quite large and allows to choose the elements necessary not only to generate direct sections of the wall and bay, but also pick up concrete panel units with the necessary thickness of the outer insulation in accordance with the specific climatic conditions.
Vertically between a dock such products through special projections (bosses), located on the upper surface of the product, such as children's building designers. Before the traditional techniques of construction of buildings in concrete panel has many advantages. Construction of private houses by this method is quick – two-storey cottage size of seven to eight meters can be traced for six weeks. The walls are relatively easy compared with the brick. Hence, the load on the foundation and the soil will be quite low. That is why the construction of such Technology is often a good solution for those owners who wish to build a warm and safe home in the area with poor soil. Also, construction technology with the use of permanent form suitable willing remodel the old house, for example, make a roof or on a standard add-storey single-story farmhouse. This will add little burden on the walls of the ground floor and basement. Expanded polystyrene is excellent retains the cold. Therefore, the structure will not have to heavily insulate with fiberglass or mineral wool slabs. To top it all Styrofoam does not rot, does not become wet and covered with mold. And do not even cause any allergic reactions. Another principal feature of the fireproof – referred to as self-extinguishing polystyrene foam materials.
Currently, the level of environmental contamination products of human activity in densely populated places reaches a critical point. This leads to the poisoning of water horizons. This problem is less acute in towns with sewerage. But in the villages who were unable to connect to a centralized sewerage system, the problem of biological wastewater treatment is in the first place. In currently in use several methods of cleaning waste water: – mechanical – chemical – biological.
The best way to waste water treatment – biological wastewater treatment. Bioremediation decides virtually all of the problems are not solved by the first two ways. It is recognized that the most effective technology for cleaning an aeration tank. All of the existing aeration tanks until recently been focused on large volumes of wastewater. The situation changed dramatically with the advent of plant range of the system 'YUBAS': 'Astra', 'CYCLONE'. These units are designed in Russia, based on experience of constructing and operating large-scale industrial aeration and fully comply with the conditions of operation in harsh Russian conditions.
In addition, purification of waste water a complete cycle, until the removal of nitrogen, and removed the activated sludge is stabilized in the aerobic conditions, it can be used as an excellent fertilizer (excellent solution to the problem of waste disposal). Plants were tested at the Research Institute of Human Ecology and Environmental them. AN Sysina and are the most effective of the entire series of purification systems presented in the present market. Reaching 98% of the treatment makes it possible to comply with all Russian standards for treated wastewater. Because of this Main Department of Sanitary and Epidemiological Surveillance recommend these settings for use throughout the Russian Federation. It only remains to add that the setup is extremely easy to use and require no maintenance of special equipment and spetspersonala. That is easy to install service makes the user. Installation is very durable, because body is made of polypropylene, which does not corrode and do not changing the structure of the sun. And the presence in the structure of the body panels foam layer contributes to the preservation of internal thermal energy of the biomass. The device operates without reducing the quality of cleaning in the winter Russian conditions. There is no need to put treatment plants near the access roads, and the appearance of the above-ground parts of the plant will not damage your YUBAS landscape. Perhaps making the installation of green-colored riding lawn. The absence of bad smells can be mounted close to the installation of structures, if necessary – in the basement. Flexibility and a unique set of characteristics needed to solve the problem of wastewater treatment makes installation of 'YUBAS' most versatile of all the system proposed in the Russian market.
