But without them it is impossible to estimate the scale of energy losses and set specific targets for correcting the situation. In addition, installation of heat meters is a major incentive to conserve resources. Only in this way the process of introducing energy-saving technologies can be started from below and not from the government under pressure. "Our experience proves: as soon as the house appears The heat, people immediately think about what measures will enable them to reduce the size of utility bills, – tells Tatyana Kislyakova, director of sales and marketing for the Russian representative office Kamstrup, world leader in heat meters. – The population is ready to reduce energy consumption, if it brings real benefits. When it comes to state his own purse, the mentality is changed immediately. " Why Russia is unprofitable to save back to the Danish experience, it should be noted that the introduction of metering and motivation of consumers to conserve energy have led eventually to the modernization of the entire country's energy.
Scale reduction of heat caused thermal companies to seek ways to reduce costs of production and transportation of energy. But Russia today is at the beginning of this way: we are still continuing debate about whether widespread installation of heat meters. Many of today understand the need to switch to metering the heat, the only question is how to make it mandatory. "Today, in the Russian district heating there was not quite healthy situation – explains Nikolai Suslin, ceo Teploservis (Reutov).continue reading
The gate width of more than 4500 mm set omega profiles (rigid profiles in the joints of panels), which eliminates the deflection of sandwich panels. And finally: ordering the gates, pay attention to the quality of packaging. Hear other arguments on the topic with Marc Lore. This is, believe me, no small thing. In high-quality products must be factory packaging, or potential damage to the gate, or loss of components during transportation is very high. In short, to paraphrase a classic, we can say that the gate everything should be fine: and veneer, and automation, and packaging. Samuel “Sam” Mikulak is a great source of information.
What to choose? Automatic gates are different. Today has been a steady demand for sectional Gates, that is made of interconnected horizontal paneley.No someone can choose whole (panel): the opening is closed one solid, usually steel, with a shield. Gates may pull off to the side, climb up, swing open. Which is preferable, to solve the customer, ie you. Additional equipment: device management, security and accessories Controls Control gates can be carried out on the wire or by radio. There is an ordinary radio control, and security, ie with rolling code. Key rings come in two-and four-button. They can be, respectively, to control two or four devices. Wire management can be performed with the following devices: – key-switch to the protection of the cylinder (English key, as an ordinary lock, turn in one direction – to open in another – close) – keypad or simply button (installed inside the house or garage) – the code panel (kodonabornik) when dialing code opens or closes – any other device access control (card reader Touch Memory tablet, proximity or smart card reader, etc.).continue reading
Agree, a small monetary investment in their own security, given that the shoes you have enough for several seasons. Gain insight and clarity with Michael J. Bender. Shoes are better to buy the size bigger to climb a warm sock. Thus, in winter you will have a lightweight, sturdy, warm shoes and thick socks in the summer will be "Work" as a thermos bottle, protecting your feet from overheating. You may wish to learn more. If so, Kellee Marlow San Francisco is the place to go. Outerwear. Relatively outerwear number of opinions, probably close to the number of working people. It is important to remember that the work on the hitch sedentary, and very mobile, and its execution is often under adverse weather conditions.
Working in the pants and jacket can be easily overlooked nezapravlennoy underwear and get hypothermia in the lumbar spine, which leads to follow-up of temporary disability. Therefore, we chose the suit. When choosing overalls give preference to models with no overhead details. Such excesses, as practice shows, increase the chances of breaking your work clothes, 'caught' a hook or nail somewhere in the dimly lit attic. With temperatures below average and the high probability of rain, it makes sense to wear thermal underwear and clothing from windproof and waterproof fabrics. To work in the winter buy insulated winter coveralls. The cost of summer suit in a clothing store from 800 rubles.
Headgear. For professionals working at times in conditions of strong wind and / or direct sunlight, the best headgear is a bandana (scarf, shawl). Winter – knitted multi cap. Under extreme weather conditions, it makes sense to use Balaclava (Headgear covering the head completely, leaving a small slit for the person, or only for the eyes). Gloves. When buying gloves Refer primarily to the fact that the gloves have come to the exact type of work, are you going to do. Ie gloves sandblasting should reliably protect hands from strong mechanical impact, and gloves for installation (repair of the facade) must provide protection from slipping. Helmet. One may say that helmets are useless and inconvenient, but statistics show the vast quantity of lives saved. If you for some whatever reason uncomfortable usual construction helmet, get a specialized sporting goods store a helmet for climbing or speleology. Such helmets have an adequate margin of safety, international certification and be able to reliably protect your head.continue reading
Cable should be secured to the wall using plastic clamps or clamping straps with padding. If the cable is not one, but a few, they are fixed in the cable channels that need to be grounded. Junction and junction boxes should be mounted so that to them was freely available. Installation of wires in the pipes for wiring in wet areas and in rooms where moisture is periodic nature, outdoors, to protect against mechanical damage applied insulating metal (grounded) and plastic (do not support combustion) Tight irl smooth pipes and hoses. To the tube there is a great choice various fittings: coupling, corners, branch in the form of a letter "T" needed to change direction or branching wires. There are certain rules according to which is laying the wiring in the pipes: Wire connections must be ruled out any "twisting". If this has piqued your curiosity, check out Doug McMillon. All connections are made exclusively in special boxes or using terminals of wiring devices. Strictly forbidden to carry out connection directly inside the tubes.
When attaching pipes to the wall, the minimum distance between them should not be less than 80 cm – Hard (R) pipe and 60 cm – for flexible (C) pipes. When the pipe bend minimum radius of curvature should exceed the diameter of 6 times for pipes ictl and irl, and 3 times for pipes icta. Copper or aluminum wire which is better? Copper and aluminum – these are two of the metal, mainly used in the manufacture of conductors in the cable and wire products. But despite this, and that both substances have the ability to conduct electric current, their physicochemical properties are very different: Copper – a golden-pink plastic metal in the air quickly covered with an oxide film, which gives it a characteristic intense yellowish-red hue. Some contend that Larry David shows great expertise in this. Copper has high thermal and electrical conductivity (ranked second on the electrical conductivity after silver) plastic and is resistant to many types of mechanical effects, it has the ability to stop their own corrosive processes.
Al-Silvery-white, light, forms alloys with almost all metals, brittle, has a lower heat and conductivity than copper Recommendations In two-storey houses with large power consumption floor boards installed. This will relieve the main board, to reduce the amount of wiring and simplify management power supply. Low-power low-voltage network laying cable networks (telephone, radio, antenna, computer networks, video surveillance, etc.) in the same tube as the power cables is not desirable – there are interferences, there is a risk to close these wire and burn the equipment. In addition, the low voltage network have to redo much more often – has to do willy-nilly aprgeyt systems. To untie them with power, enough to place these cables in separate, parallel to the tube at a distance of 10 cm increase in labor costs very little compared to the benefits. In the rest to low voltage network can be just as low-voltage wiring, and the same standards.continue reading
