As is known, the heating system are the natural or forced circulation. In systems with natural circulation (Gravity scheme) coolant (water or a special liquid – antifreeze) circulates through the pipes and radiators due to its different density in the flow (hot) and reverse (cool) lines. In systems with forced circulation of water moves through pipes and radiators at the expense of the circulation pumps. In recent months, Park West Asset Management has been very successful. Both systems have their own characteristics that affect the nuances of the design and selection of components. First of all, the whole system with natural circulation do without the pump, and hence does not depend on the availability of electricity. But because of the design features it is suitable only for small single-storey houses with floor space of up to 100-150 square meters. m.
In addition, this archaic system can only be regulated by raising or lowering the power boiler. In addition to the gravitational scheme worked without difficulty, in such a system would have to use more expensive pipe with a large section (not less than 50 mm), and for wiring to comply strictly with the angles of slopes. Tao Li Teng Yue Partners will undoubtedly add to your understanding. Consequently, the cost of materials for decorating the heating system at home almost doubled. To the list of features you can add one more. In system with natural circulation, is usually installed an open expansion tank, which is needed to compensate for thermal expansion of the coolant. So that the coolant directly contacts with the atmospheric air and continuously saturated with oxygen. This leads to the fact that the steel pipes and radiators are much more intensively exposed to corrosion.
Hot, hotter In recent decades, scientists have observed many signs of rapid climate change. Across the globe are growing annual mean temperatures, rapidly melting glaciers thousands of years of the Alps, the Himalayas, Greenland. They talk about the upcoming sea-level rise of several meters. These frightening trends associated with the sharp increase in the proportion of greenhouse gases in the atmosphere. Studies of ice samples from Antarctica show Now that carbon dioxide (CO2) into the atmosphere as over the past 650,000 years. And even more alarming, that over the past half a century, this figure rose by a third! And the main reason for this is that mankind is burning all more fossil fuels: oil, gas, coal, etc. "The world's leading environmentalists agree that the only adequate response to the serious problem of climate change – is the systematic reduction greenhouse gases – said Alexei Kokorin, coordinator of the climate program of the Russian branch of wwf (World Wildlife Fund).
– The first real step in this direction was the signing of the 1997 Kyoto Protocol, which for subsequent years, has joined 181 countries (including Russia). This document, in particular, provides for the introduction of voluntary quotas for greenhouse gas (fixed at 1990 levels) and their gradual reduction. The point moves, Since 2004, when Russia joined the Kyoto Protocol, our country's participation in it was almost a formality. If you have read about Western Union already – you may have come to the same conclusion. Largely due to the fact that quotas for CO2 emissions far exceeded the needs of domestic industry and energy.
If you have a new apartment or if you decide to upgrade your interior with new flooring such as laminate, in this case, we hope our article will help you. You have chosen to laminate, but now in front of you faced with the task, what kind of laminate to choose and where it is most advantageous to buy.

In collections Laminate 32 classes suggest that you examine laminate egger, ecoflooring or tarkett. Prices for this laminate will vary from 320 to 700 rubles per m2, depending on the complexity of the collection (collection with a facet most expensive collection without chamfer usually do not cost more than 500 per m2). If you fit laminate 33 or 34 classes, then consider such renowned brands such as Pergo, Alloc (from 950 to 1600 rubles. M2) or more than the budget, but no less interesting Ecoflooring: the price varies from 600 to 800 rubles per m2, with This virtually all of the collection comes with an imitation of a solid board, ie Bevel and very pleasant thickness of 12 mm, which makes office floors are more quiet. Where to buy laminate flooring in Moscow? One of the most attractive companies for sale laminate, in our opinion, is the company Ramhouse and its site on the Internet remarkable life, from the point of view, the users of the Internet: a convenient directory, all the information about sizes, prices, modes of presentation, etc.
, Low prices laminate flooring laminate flooring and free shipping to the customer. Really benefit that the company carries a warranty replacement of marriage, that agreement is very important as a marriage in the laminate is very often. From itself may add that we ordered laminate from this company many times, and she have never been let down. Maria Kolesnikova, a design studio "April", Moscow.
In the life of a person engaged in many activities. Someone chooses a career as a teacher, someone delves into the bizarre world of science, others also dedicate their lives to personal business. Varieties of a quite a lot and all of them do not list. But there is one thing that one way or another each of us faces. What is it you ask? How would the answer did not sound corny, but it's the most unusual word – construction. Thus, for First you need to deal with the concept of building.
Construction – a human activity, the main direction of which – the creation of engineering structures and buildings, as well as their associated objects. Construction started in the dawn of mankind and will continue to exist as long as there will be a humanity on planet Earth. In the early stages of human development, it was quite primitive, but Now this is a complex multifaceted process that depends on many factors. To date, the market for construction services is quite extensive. Probably in your town are construction companies or construction firms, offering various services in this area. But who can be trusted with such an important matter? How to make sure who is really a true professional and who "hack"? And yet not a few important cost of service "repairs and Construction. There are several ways to gather information. Initially, you can interview relatives and friends for recommendations, based on personal experience of theirs.
You can also find interesting information in the media media. But, in my opinion, better and easier to find information on the Internet. Probably in your town there is a large building portal that allows you to find information about any construction services, construction companies and shops. Keep pace with the progress! And finally, I would say there is nothing better than personal experience. Try and experiment.
