What engineering networks may be present in a wooden house

Engineering networks are one of the most important stages of construction country house. The quality and ease of use of your future home largely depend on them. Today there is a huge variety of materials for every taste and budget. To understand the issue, it is necessary to understand the components in more detail.

HVAC: heating, water supply, sewerage, underfloor heating and boiler room.
Integral systems in a residential building, possibly with the exception of underfloor heating. A variety of modern heating and cleaning systems, generators can solve any difficulties faced by the owners of future homes.

EOM - power electrical equipment and electric lighting.
This section includes lighting devices, socket groups, switches, power engineering equipment. Automation is also possible engineering networks, installation of an intelligent system "smart home" and visual interactive control. The EOM section also includes on-site networks: architectural and landscape lighting, backup power.

SS - low current networks.
This section is very diverse and basically contains modern systems control, security, communication and entertainment. The main groups of networks: fire and security alarms, video surveillance, intercom, TV, Wi-Fi, Internet, multi-room and others.

V&K - ventilation, air conditioning and humidification.
In fact, ventilation wooden house- it's everyone's choice, like air conditioning. Ventilation is always present in the house in the form of necessary things (hoods from the control room, dressing rooms, kitchen), or it can be a supply and exhaust. In this case, a system of channels for inflow and intake of air from the premises is bred in the ceilings; the channels, in turn, are connected to the ventilation unit, through which the required air exchange rate is maintained.

As for the installation of automatic humidification in a wooden house, this is extremely useful thing. Stable indoor humidity has a beneficial effect on the quality and durability of all wooden structures. Air conditioning in a wooden house is conveniently performed in the form of a VRV system, distinctive feature which is the possibility of servicing several executive units (air conditioners) at the expense of one outdoor module. In other words, there are many air conditioners inside the house, and there is only one outdoor unit - stationary, and can be located at some distance from the building.

Pool equipment.
The presence of a pool in a wooden house is not uncommon today. In order to choose the right size and type of equipment, the first thing to do is to decide on the purpose and frequency of use: is the pool for swimming or for relaxation, or maybe for refreshing procedures after the sauna? Do you need countercurrent or hydromassage? How often will you use the pool? All calculations and selection of equipment occur at the design stage. Installation of pool systems is carried out sequentially, in parallel with the finishing work.

To start the installation of engineering systems, several conditions must be met: a constant temperature above +10 degrees indoors, the presence of basic supporting structures to which each of the systems is tied in the literal and figurative sense, and, most importantly, the project. A quality project is 50% success. The installation of systems always takes place in stages and is divided into the installation of routes and terminal devices.

The cost of engineering systems for a wooden house

The total costs of engineering networks are directly dependent on two factors: the complexity of the systems, as well as the price category of the materials used and the end devices used in the installation. Eg:

• A heating radiator can cost 60€ or 400€ (depending on the type, material and manufacturer);
• A pipe for heating distribution can cost 2€/m.p., or maybe 4€/m.p.;
• The equipment of a pool of the same area can cost 1,000,000 rubles, or maybe 6,000,000 rubles.

And so in everything. But for convenience, you can rely on the following figures: for a simple wooden house, using middle-class materials, the cost of engineering systems will be from 160 € / m2 of living space (including installation work). This cost will include the necessary networks, such as water supply, sewerage, heating, boiler room, underfloor heating in the necessary premises, routes lighting fixtures, socket groups, switches.

The possibilities of technological progress have saved a person from having to make a painful choice between an organized existence in a metropolis and a free life in nature. Today, you can create comfortable conditions anywhere, and country houses are equipped no worse (and often better) than urban housing.

Engineering communications of a country house include electricity, cold and hot water supply, heating and sewerage. Even if the house is located far from centralized networks, there is nothing fundamentally impossible in organizing a well-thought-out engineering infrastructure.

Overview of engineering systems

Often the owners suburban area there is no possibility of connection to the main heating main and water supply. Then they face the need to organize their own, home life support systems. In a modern country cottage, all the main engineering systems are laid; if their design and installation is carried out without errors, the owners will not have problems during operation.

Water supply

Centralized plumbing systems reliably and constantly provide Vacation home clean water. The vast majority of private buildings are located far from such a convenient source of water. If the main systems are not available, the construction company will develop an autonomous water supply system. A country cottage can be provided with clean drinking water in two ways:

Individual well. A simple and fairly budgetary way of individual water supply. A well is dug if the depth of the aquifers is small (up to 30 m), a pump and a filter are installed.

Depth of the aquifer for different types water supply Source zen.yandex.ru

Individual well. The type of water well depends on the mode of use of housing. If they live in the house periodically, a sand well (up to 40 m) will be optimal. The depth of an artesian well reaches 200 m; water from such an aquifer is enough for a small village. To drill artesian well, you need a license.

A well-thought-out arrangement of water inlet to the house, wet rooms (kitchens, bathrooms, saunas) and wastewater outlet will help to avoid problems during operation. You should also take care of the quality of pipes and fittings; saving on these things is unacceptable.

A couple of decades ago, summer residents, in order to swim or wash, heated water with buckets. Modern hot water supply is much more practical. Hot water flows from the tap, and heats it up with a boiler, electric or gas.

Drilling a well for water

Sewerage

If it is not possible to connect to a centralized sewerage system, the civilized way out will be to equip an autonomous system for the removal and treatment of wastewater. practical way will be the installation of an individual septic tank, a facility capable of treating up to 20 m 3 of wastewater (depending on the model chosen) per day. The septic tank is placed taking into account the height of groundwater and sanitary requirements. The main technological options ( cesspool, as a morally obsolete option, we do not consider) is:

Arrangement of a concrete septic tank- a system of 1-3 wells that purifies wastewater to an acceptable quality. The output is industrial water suitable for irrigation.

Station biological treatment . An underground reservoir, most often made of plastic and consisting of 1-3 chambers. A more advanced and expensive option with a guarantee of long (up to 50 years) functioning and processing of a significant amount of wastewater. Purified water can also be used to irrigate the site.

Heating

No communications in a private house will be complete if it does not have its own heating. Autonomous heating is a popular engineering system, the features of which are:

Heat source. Heating is implemented in various ways, but the main element is always the heating boiler. It can run on diesel, gas, electric or solid fuel energy. Installation of gas or electric heating in a wooden house requires increased measures fire safety.

Device. For heating in the premises, radiators are installed. Most often, aluminum, steel, cast iron and bimetallic radiators are used.

Alternative. You can heat the house by adding (or completely replacing) heating radiators warm floors with liquid coolant; they are most often mounted in the hallway, in bathrooms or bathrooms. The system is preferred to be installed in the kitchen if there is a ceramic tile. Experts advise to arrange underfloor heating if the house is being built not on a strip foundation, but on reinforced concrete slabs. For the installation of underfloor heating, metal-plastic or polyethylene pipes are used; after testing the system, a cement-sand screed is arranged.

Manufacturability. Modern turnkey heating communications (including wood-fired boilers) operate in automatic or semi-automatic mode, which greatly simplifies management and saves money.

Variety of models. If the country cottage is small or used periodically, it is advisable to choose a compact wall-mounted model that is convenient to place in the kitchen. For a large house, a multi-circuit system is suitable, for which you will need to allocate a room equipped with ventilation and a chimney. It can not only heat water for household needs and warm the air in the ventilation system, but also heat the floors and water in the pool. A powerful system is able to heat neighboring buildings.

Ventilation system

An engineering system that is increasingly becoming necessary for a country house. Air circulation in a private house is organized in several ways: there is a natural, forced (using fans) and a mixed type. According to the principle of operation, there are supply, exhaust and supply and exhaust systems.

In modern country cottages, a forced supply and exhaust ventilation system is often implemented. Supply and exhaust ventilation is compact, economical and able to filter, heat or cool the air.

Gas supply

Natural gas, one of the most budgetary and affordable types of fuel, is used in everyday life in several ways. With its help, they heat the house and cook food, and recently they have also been used for design - gas fireplaces have become fashionable. The easiest way to gasify a house is to connect it to the central gas pipeline. Alternative option is the installation of a storage tank for liquefied gas.

Design of engineering systems of a country house: the nuances of preparation

Engineering systems and communications are a costly part of construction; their cost can reach 25-35% of the estimate. Such an expensive component requires special attention during selection and installation; otherwise, the cost of rework or repair will be too high. The best option arrangement of engineering systems is their planning and design simultaneously with the house and laying in compliance with the construction stages. Before starting the design, consider the following factors:

Budget framework.

Features of home operation. Whether the owners want to live in the house permanently or periodically. It is also important how many people will live in the cottage, and what home appliances will be installed.

Features of laying networks. A country house often has two floors and an area larger than a city apartment. The load on engineering communications will be higher, and more powerful equipment will be required. If backbone networks are not available, an alternative (stand-alone) solution will have to be developed.

After studying the conditions and wishes of the customer, the following is developed:

Preliminary design. circuit diagram, which includes the necessary systems.

Technical task. Includes a scheme of engineering networks, detailed drawings for laying communications, a preliminary estimate.

When developing terms of reference Important details are taken into account:

Determined relative location of the house, outbuildings, a well (well) and a septic tank. This will help determine the length of external engineering systems, the method of laying them (open or closed) and winding into the premises.

Calculated water consumption. This is done based on data on the area of ​​the cottage, the number of residents, the method of heating.

Calculated power consumption at home (based on the calculation of the amount of consumption of household appliances and devices). Based on these data, electrical wiring and protective devices are selected, a place for mounting the switchboard is determined.

Method of supplying electricity. If the nearest pole is far away (more than 25 m), you will need to install an intermediate pole or run an underground cable.

Cottage engineering communications: automation and reliability

A country house has long ceased to be a place for summer holidays. Many families live outside the city all year round, so perfect work is required from engineering systems. If electricity goes out for several hours in a city apartment in winter, it will look like an annoying nuisance that does not seriously affect anything. If this happens in a private house with autonomous communications, the plumbing, heating and sewerage systems may freeze, which can only be called a disaster.

A new generation of engineering communications in a private house has a high level of automation. They are able to work efficiently and reliably, coping with the increased demands and pressures of modern life:

House area. In most cases, it exceeds the area of ​​urban housing, which implies an increased engineering load.

Number of equipment. In country cottages, not only dishwashers, jacuzzis and home theaters are installed. Often the house is decorated with an indoor swimming pool or a wellness center, and a security and fire alarm system monitors the order.

Automation greatly simplifies the management of home systems Source proexpress.com.ua

Increasingly, the automation of suburban housing is carried out in a complex way (the "Smart House" system), with maximum control and computer control. The equipment of the system is not cheap, but in the future it allows you to save time and money, as well as reliably solve several problems:

Choose the optimal load with which the systems will work.

Develop a dynamic system with the possibility of flexible management and modernization. The owners will be able to set the operating mode for alarms and CCTV cameras. It is not difficult to set an on and off schedule for lamps, blinds, household appliances, computer or music center.

Set up a disaster prevention system(cutting off gas or water) and danger alerts.

Installation of utilities in a turnkey private house

Profile construction companies offer services for the design and installation of engineering communications. The cost of engineering communications can be estimated after studying the design of the house; an integrated approach allows you to take into account all the technological nuances:

Correct connection to existing infrastructures, taking into account their proximity and capacity.

Design of home engineering systems with an assessment of safety, reference to the terrain, proximity to the routes and seismicity of the area.

Design of external networks. A project is being developed for the water supply and sewerage network, the supply of electricity and gas, drainage system. The type of heating, the design of the boiler room, external lighting, drainage system, communication are being considered.

Design of internal networks. The piping, electrical network, ventilation and air conditioning, filtration and purification systems are being thought out. At the request of the owners added fire alarm and security system.

Coordination. All projects are drawn up taking into account fire and sanitary standards and are checked for compliance with the rules of SNiP and GOST.

The optimal solution for the owner of a country cottage will be the order of all design and installation work in one construction company. This will save money and eliminate the need to find a contractor for each engineering system and subsequent control and coordination of work. A complex order of such complex projects guarantees high-quality execution and reliable functioning of all life support systems in your home.

Country wooden housing construction is constantly developing, and houses are becoming more and more comfortable. Gone are the rustic log huts with outdoor amenities and electricity as the only boon of civilization. Now wooden houses and baths are being built with all utilities: heating, water supply, sewerage, ventilation. But we must remember that the conduct of communications in a wooden house and a bath has its own characteristics and requires closer attention. Specialists of the company "Wooden Houses and Baths" know how to install engineering communications that will improve the quality of life and be 100% safe.
Already starting from the design of the house, it is necessary to think about the schemes for supplying and placing life support facilities. It is best when engineering communications in wooden houses and baths are included in the project of a house or bath. When arranging the foundation, it is necessary to take into account the entry points of the water pipes and the exit of the sewer pipe, so that later you do not waste time and effort punching channels in the foundation for them. Also, already in the process of construction, it is necessary to leave holes, channels, perform additional work for future internal pipelines and other highways. Thus, later it will not be necessary to complete or rebuild something, violate the integrity of what has been done, spend extra effort and money.
Engineering work is carried out only after the complete shrinkage of the house or bath, in order to avoid possible damage to communications due to ongoing shrinkage. Pipelines are laid hidden before the walls are finished or on top of already finished walls. Concealed wiring has the disadvantage that in the event of an accident or repair work, it will be necessary to disassemble the trim to access the required section of the pipeline.

Heating and boiler room in a wooden house and sauna

Most often wooden heating, separately standing house carried out from an individual boiler. Regardless of the type of fuel with which the boiler is heated, heating and a boiler room in a wooden house and a bathhouse represent an increased fire hazard. The boiler must be installed on a solid foundation, in a room with supply and exhaust ventilation. Walls closer than 1.0 meters from the boiler are lined with heat-resistant non-combustible material.
Particular attention is paid to the passage of chimneys through the ceiling and roof structures. Today, in order not to violate the integrity of floors and roofs, more and more often chimney systems are installed on the outer street side of the walls and safe double-circuit chimneys are used. Manufacturers produce not only the pipes themselves, but also the necessary fittings and various fasteners, the use of which makes the heating system completely safe. Radiators in wooden houses are installed under the windows, but besides this, water-heated floors are often installed simultaneously with radiators in houses. To conduct heating pipes to heating elements, a wiring diagram must be developed, because heating is a complex engineering system.

Water supply wooden houses and baths

So that the installation of a water supply system in a wooden house and a bathhouse is not complicated by unforeseen work, already in the process of building walls, it is necessary to develop a scheme for the internal wiring of pipes from the input to the points where water will be used. According to the scheme, holes are made in the walls for pipes to pass through them, strobes are cut through. Water pipes are laid after the complete shrinkage of the log house or bathhouse, since with continued shrinkage, the pipes installed perpendicular to the log crowns will be deformed.
Water supply of wooden houses and baths from a well or a well is carried out by laying pipes at a depth of more than 1.2 meters, in a special Utility room. The room is equipped with an automatic pumping station, which creates constant pressure in pipes and water purification systems, from which water is delivered through pipes to places of consumption. The input from the centralized water supply is done directly into the pipes, divorced around the house.

Electrical wiring in wooden houses and baths

Electrical wiring in wooden houses and baths is carried out according to wiring diagrams, taking into account fire safety. In the case of hidden wiring, the wires are laid along the walls in a metal hose, junction boxes, metering devices and control panels must be installed so that they have free access, after completion finishing works. It is safer and more affordable to conduct wires from above, along already finished walls in cable channels, which today can be matched to match any finish. Considering the high humidity in the bath, the lighting of the shower room and especially the steam room is allowed only with special lamps with sealed fittings.

Sewerage in wooden houses and baths

The sewerage device in a wooden house or bathhouse practically does not differ from the same work in any other case. It is desirable, already in the process of building the foundation, to lay a large-diameter pipe leading to the septic tank into it, and the rest of the wiring of sewer pipes can be carried out at any time in the basement of the house. On the premises of the bathhouse, sewer pipes are diluted to the installation of wooden floors or to concreting the base for tiled floors. Sewer pipes from the second floor to the basement, if this is laid down in the project of the house, are laid through the ceilings and along the walls until finishing, so that during finishing work, they could be decorated.

Ventilation in wooden houses and baths

Wooden houses and baths differ from other buildings in that their walls "breathe" creating natural air circulation, so it is dry and healthy in them. The device of a forced ventilation system is necessary only in the boiler room, in the kitchen, in the steam room and in the sanitary facilities. To maintain a normal microclimate in other rooms, simple ventilation is often sufficient.
The installation of turnkey engineering communications by the Wooden Houses and Baths company improves the quality of life and contributes to the preservation of all structures that make up a house or a bathhouse.

After the annual shrinkage of a wooden house, it is time to carry out communication systems. Masters of the company "MariSrub" will perform a phased competent design of heating and sewerage, water supply and electricity. After the coordination and approval of the project, experienced employees will promptly and efficiently perform the installation of engineering systems.

Design

Design, calculations and drawing up diagrams are a necessary part of the installation of communications in a country house. The company's engineers will carry out the project in strict accordance with the established norms and rules. We perform the following works:

• Thermal calculation;

• Boiler project;

• Heating project;

• Ventilation project;

• Wiring project;

• Sewerage and water supply project.

The company's specialists will help you choose suitable and reliable equipment, calculate the required volume and cost of materials.

Installation of electricity in a wooden house requires special care and responsibility, certain knowledge and skills. In this case, the list of fire requirements is expanding. Experienced craftsmen"MariSrub" company will perform the installation of electricians in a wooden cottage, country house or a bathhouse in accordance with building codes and regulations (SNiP) and electrical installation rules (PUE).

We lay the introductory cable through the air and in the trench. We organize internal wiring open and closed. Install switchboards, electrical appliances, switches and switches, sockets.

Heating system installation

Install various systems heating depending on the type of building and location. For gasified areas suitable option will become water heating using a gas boiler. This is a rational and easy way to heat. We lay one-pipe and two-pipe systems.

If there is no gas in the area, it is rational to choose an electric heating system. Especially popular is the “warm floor” and the use of standard electric heaters. We will select and install the necessary equipment.

Installation of water supply and sewerage

The country house is connected to the central water supply or to autonomous water sources. Wells and wells are distinguished among such sources. For water supply equipment in a private house, you will need a pumping station, a hydraulic accumulator and a reservoir for storing water. In addition, it is necessary to install coarse and fine filters to protect the water source from contamination. To transport water to the house, steel, copper or polymer pipes are laid.

Sewerage requires a local installation with the principle of deep biological treatment. Such installations are environmentally friendly and do not require additional maintenance. They are practical and easy to use. Pipelines inside the house are mounted from pvc pipes, as it is a durable and inexpensive material.

Before installing water supply and sewerage systems, specialists will develop a network layout, measure the depth of the sewer pipeline and measure the height of groundwater. Install a well or well, a pit for the tank. The latter, by the way, is located at least five meters from the building.

Ventilation in a wooden house

The tree "breathes" and supplies oxygen to the room, but natural ventilation, even in a log house, is not enough for a comfortable life. The accumulation of condensation on the walls causes mold and fungus, which destroys the wood and spoils the appearance.

The company's masters will install a supply and exhaust (forced) ventilation system. Such ventilation guarantees stable and normal air exchange, eliminates unpleasant odors in the room. Special fans provide fresh air and, if necessary, heat the room.

During the construction of a wooden house, the issue of laying engineering networks and electrical wiring is among the priorities. Laying communications in a wooden country house is more difficult than, say, in a frame or brick one. The complexity is caused by the specifics of such buildings, their design features and wall shrinkage.

All technical issues related to the installation of engineering communications should be taken into account at the design stage, but even best projects wooden houses do not always fully reflect all the nuances, and very often you have to solve various non-standard issues, already building a house.

First of all, a wooden house requires a separate room, in which the main communications will be concentrated. Their wiring around the house should be carried out either in interfloor ceilings, or, if these are vertical risers, in boxes.

The wooden house has a very important point- this is the shrinkage of the walls, which in the first three years is approximately 3%, and therefore all communications should be divorced taking into account this feature.

Water supply, sewerage and heating of a wooden house

A country wooden house, as a rule, is cut off from centralized water supply, heating and sewerage, so these issues must be resolved even before construction. Water is usually supplied to a country house from a well or well, and equipment that creates constant pressure is installed in the house or in an additional technical room (boiler room). The issue of heating is solved by installing an electric or gas boiler, and the issue of sewerage is solved by installing a septic tank.

Since the run-up in prices for heating equipment, radiators, pipes, pumps, components, etc. is high, then the estimated costs for the installation of communications can differ significantly from each other.(based on a house with a total area of ​​120-130 m2) sewerage, water supply and heating deviceswill be 2,200 rublesexcluding costs: 1. For drilling and equipment of a well, wiring and insulation of pipes for supplying water to the house. 2. The cost of the heating boiler ( the cost of the water heater is included in the price per m2). 3. Shower cabins, toilet bowls, sinks ( connection is included in the price per m2) 4. Cost and installation of a septic tank.

Ventilation

A ventilation system is needed to remove unpleasant odors and supply of fresh air. It can be very simple: hoods in the bathrooms, in the kitchen and in the boiler room, while fresh air enters through the windows and ventilation ducts in glass panes. But it is also possible to make a system of forced supply and exhaust ventilation with fans and air ducts, which provides constant air exchange. In this case, at the design stage, it is necessary to provide a place for the distribution of air ducts.

Wiring in a wooden house

By Soviet standards, hidden wiring in wooden houses was unacceptable, but modern technologies made it possible to lay wiring even in a wooden frame. For this, a double-insulated cable is used, retractable into a metal hose. The cable, protected by a metal hose, is laid in interfloor ceilings and is conducted without connections and "soldering" boxes from a point to an electrical panel. Sockets, as a rule, are placed in the lower crown of the building, and switches are located near the door, pulling the wiring from the floor through a wooden jamb. When designing electrical wiring, you need to take into account the features of the design project, and clearly calculate all the necessary sockets and lamps, because, having built a house, adding a wire in a hidden way will be problematic .

Estimated price per square meter(based on a house with a total area of ​​120-130 m2) electrical wiringwill be 1,300 rubles.
