Articles about real estate | Autonomous house: to live outside the city and no one could depend on Life outside the city - not just the fresh forest air, but also a lot of problems. Communication laid decades ago, often can not cope with the influx of wanting to live close to nature. That maintenance work, then crash, then a new neighbor is connected to the mains and leave for several hours without electricity the entire quarter. And somewhere there is no such benefits: a transmission line is not paved, gas lines away, and the local water utility in no hurry to reach new horizons. It is time to think about housing, which will not depend on the central communications. Own gas, electricity, running water. Is this possible? And anyway, how to make suburban life as independent of external factors?

Give power!

The main question - electricity. From it in varying degrees, depend all communication.

Some owners of cottages to decide whether the independent power generator purchase. Since this will be the sole source of supply of energy at home, walk to a choice must be seriously. It must be reliable, safe to consume an optimal amount of fuel and, of course, produce a minimum of noise.

The main two types of generators - gasoline and diesel. Continuous running GASOLINE - less than 12 hours, power - a maximum of 15 kVA (13.5 kW). Usually they are kept in cottages "just in case" and run only when electricity is turned off.

For constant power supply at home will suit the diesel generator. He is more powerful than gasoline and has a greater share of work. Diesel engine fire safe. Absolutely silent to call it, of course, impossible, but it hums noticeably quieter than its gasoline counterpart. The main advantage of diesel-powered mini-power plants (both are called generators) - this is an opportunity to save on electricity. Diesel fuel is relatively inexpensive, at least, cheaper than gasoline. Maintenance of diesel generators require minimal, and its service life - over 20 years. So for owners of suburban housing diesel power - solution to the problem.

You can go to the issue of energy supply cabin even further - to install mini-CHP. Thermal power plants are turbines, gas-piston and a mini-turbine. First applied to power large industrial enterprises and entire neighborhoods.

For home energy fit the latter two options. Places such CHP took a little bit. Construction is about two meters in length and approximately 1.5 meters in width and height. Set it in the back room or next to the cottage, under a canopy. Over the next computer system, so that the hiring of a special operator is not necessary. CHP can be equipped with sensors of gas leaks, fire and security systems. This makes them as safe. The term of operation of mini-CHP - 25-30 years.

What advantages does its own CHP compared to social networks?

* First, independently of the central power station.
* Second, in addition to its direct "duty" - to generate electricity, CHP will provide another cottage and hot water. The fact that the production of electricity generates heat, which is on the powerful central power plants is simply discarded. Thermal energy CHP is directed to heating and hot water at home. Thus, heating homes and hot water user CHP will do for free. Quite significant bonus, is not it?
* Third, its heat is cheaper. Cost of CHP is commensurate with pay to connect to the central power grid. For example, in Moscow to connect to the network is 45 000 rubles per 1 kW of installed capacity. Within a few years (from 2 to 6) the cost of installation of mini-CHP will be repaid, since the annual expenditure on its maintenance is much lower than the charges for electricity to local networks. According to specialists, you can save up to 50 cents from every 1 kWh. Given that electricity prices are constantly rising, own electricity would not want.

Insulation - a step toward independence

The logical conclusion: the less energy consumed, the less dependent on its source. It is not about saving energy by limiting its consumption, this principle does not correspond to the notion of "comfortable life". The question is another: how to keep warm in the house?

The warmer the walls, roof, floor homes, the less heat goes out. Hence, fewer resources required for space heating. In Europe and the U.S. about energy efficiency (minimum consumption of heat and electricity), buildings began to think quite a long time. Gradually, this trend has reached and to our country.

The main factor energy efficiency of the building - a quality insulation. About her need to be concerned in advance, even before construction begins.

Facade, roof, pipes, floors, windows and doors - to minimize heat loss at all sites are well insulated with them.

The first thing that you should pay attention to when choosing insulation material - thermal conductivity. The lower it is, the better. Important and hydrophobicity - the ability to not absorb moisture as well as reliability, durability, fire resistance, environmental friendliness, ease of installation. And in some cases, we choose the material with minimum weight.

Fibrous mineral wool insulation (glass wool, stone wool) - the most common category of products for private housing. Glass wool has low thermal conductivity, it's light and fireproof. But the glass is subject to shrinkage. Therefore, after a few years the quality of insulation can be affected negatively.

Stone wool shrinkage is not affected, environmentally friendly and, most importantly, durable. This is a non-combustible material. Rock wool fibers under the influence of fire does not melt, maintaining the temperature to 1000 ° C. Moreover, in case of fire, such insulation can significantly delay the spread of flames and keep the collapse of structures. So that the security is perhaps the best option.

For example, for the insulation of the fa?ade system can be used ROCKWOOL ROCKFACADE (the world's leading manufacturer of stone wool insulation). She not only performs its direct function - retains heat in the house, but also protects the outer wall of the building from heat, moisture, wind and cold. The fact that stone-wool has a high vapor permeability. Air with high humidity, which inevitably appears in the living room, through a layer of insulation freely come out. Thus, the wall will always remain dry and will last much longer.

If it is necessary to warm floors, pitched roof, attic, inside walls, floor on sleepers, suitable light plate ROCKWOOL LITE BATTS ™ technology Flexi. This new product has an elastic edge - one side of the material and tightened easily inserted into the frame, and then straightened it. To cope with warming could any housewife.

High-quality thermal insulation to protect the house and from the winter cold and the summer heat. In any weather at home will be a pleasant climate. CHP or purchased traffic kilowatts - whatever way was received warmly, it must remain with you. For the cottage in which the central role played by autonomous life support system, it is especially important.

And we have a cottage gas ...

Autonomous system of gas supply in some cases, not just the desire to make your home independent of the city gas services is a necessity.

Oddly enough, in our country where, according to expert estimates, reserves of natural gas will last for the next 100 years, there are still areas in which the trunk of the gas can only dream of. However, something where the pressure differences in the central conduit happen so often that it fit to think about their own gas storage.

It's real. Gas tank - capacity cylindrical volume of several thousand liters - buried under the ground at a distance of about 10 meters from the house. One - three times a year to replenish the reservoir of liquefied gas - propane or butane. Such a system is designed for 20 - 30 years of service.

The cost of installing the gas tank a few times or even dozens of times more expensive than connecting to the backbone. True, in some regions of Russia the price for connection to a central gas supply system are so high that own gas tank costs only slightly more expensive. Pays off its gas within a few years because it is cheaper to use electricity the central power grid.

... And your plumbing!

With a central water supply in the suburban towns of the case did not always fare better way. There are areas to which water utility networks have not yet have reached, and when the reach is unknown. But it does not hurt to provide the house with clean water. Not for nothing called the blue planet Earth: the water we have almost everywhere. We only need to drill a well of sufficient depth.

Neither well nor sandy hole depth of 30 - 35 meters will not provide the necessary quantity of water cottage, and the quality of such water will not be the best. These options are suitable only for summer cottages. For a modern country house needs a well in a few tens of meters. In the south of Moscow region groundwater at a depth of 40 to 70 meters in the northeast suburbs will have to drill to a depth of 200 meters. Which breed separates the site from groundwater - clay, granite, limestone, - also must be considered. Everything related to water and soil at the site, please contact your local companies engaged in drilling wells.

Since drilling - a costly process, it is better to think about the water supply at home even before it was built, and even before the purchased lot. Thus, the opportunity to get your water is. Hence, we can not depend on the availability of central water system, buying a house or land, even in the far corner from the bustle of the city.

Clean air, river and forest ... In recent years, more and more people are dreaming to settle away from the noisy and gas-polluted cities. In our country, with its vast territory, the opportunity to stay close to nature more than enough. The only problem: the more remote friendly green corner of the city, the lower the conditions for a comfortable life. But man - being stubborn: if the benefits of civilization is not ready, he seeks to create them. Therefore, their own electricity, gas and water are becoming the norm. Modern technologies that help make housing autonomous, give freedom to live where you want.
