Gas heating of a house with an attic - prices, calculation, a ready-made example

Attic heating

Attic is an attic-type room in residential buildings. Carrying out utilities and heating the attic are the necessary conditions for the comfortable use of the room as a bedroom, playroom, nursery, office. The attic heating system solves a number of tasks:

maintains a stable positive temperature in the cold season,
does not allow freezing of the room,
prevents the formation of ice and a decrease in the performance of building and finishing materials.

Correctly designed attic heating in the house consumes a minimum amount of energy, does not increase its consumption during the heating season, allows you to regulate the temperature in the room and is responsible for a healthy microclimate.

Heating the attic: modern methods

There are several ways to heat the attic in a bathhouse and a country house. The first of them is the connection to the common boiler room of the cottage. A pipeline is laid in the attic, radiators are installed through which the coolant circulates - water heated in the boiler room. When choosing the best way to warm up the room, it is recommended to take into account the following disadvantages of the attic water heating system:

The load on the boiler increases: if initially it was not designed to heat the attic, then the temperature in other rooms will drop, and fuel consumption will increase.
The attic is removed from the boiler: the coolant reaches the attic with a low temperature, having already given off heat to other rooms. This reduces the efficiency of heating the attic, or leads to the need to install a large number of radiators.

Benefits of using solar energy for attic heating

Autonomy.
Solar heating equipment does not need to be connected to the mains or use any other fuel.
Ease of installation.
Products are installed on walls or roofs. Installation is simple and quick, no complicated project documentation is required.
Effective work.
The devices maintain a positive attic temperature throughout the autumn-winter period.

Attic heating with solar energy is used in residential buildings in the USA, Canada, Russia, Europe and the CIS.

What type of heating (heating) to choose for the attic of the house?

There are many modern home heating options. Heating options can be roughly divided into two groups. The first one is based on the type of fuel used in the heating system:

• Gas. The system is based on a gas boiler, gas to which is supplied from the main (belonging to the cottage village, DNT, SNT, etc.) or from a gas tank (a specially equipped tank that is installed on the site near your house and refueled by gas delivery services to your home ) or cylinders (ordered at regular intervals by the owner of the house). This option, as a rule, is the most common because of the ease of maintenance of the system and low costs for the purchase of gas.

• Electrical. The electric boiler is responsible for heating the coolant when choosing this heating option. Ease of operation and minimal labor costs for heating maintenance in this case are combined with a fairly high power consumption. At the same time, the cost of heating directly depends on the current electricity tariffs.

• Heating with solid or liquid fuel.In modern country houses, this heating option gives way to easier-to-use and popular heating options - gas and electric. When deciding on the choice of a heating option with a solid fuel boiler, it is recommended to carefully evaluate the time and effort required for self-refueling of the boiler with fuel (wood, pellets, diesel fuel, etc.). The cost of maintaining the system in this case will depend on the price of the selected fuel option.

• Alternative (from the heat of the earth, solar or wind energy) - the least popular heating options among our customers, due to the high cost of equipment, its installation and adjustment and, as a result, a long payback period of the system.

In cases where the country house temporarily does not have the ability to connect gas or electricity, you can choose the option of combined heating, in which it will be possible to configure the initial use of a reserve type of fuel, and later - the main one.

For a comfortable stay in the house, you can supplement the heating system with various automation options, which will help maintain the optimal temperature level, reduce heating costs and even provide you with the possibility of remote control.

The second conditional group of heating options - according to equipment options that directly transfers heat to the room:

• Heating with radiators (or floor convectors) is a classic, more economical option for heating a country house. As a rule, radiators are placed near windows. If a country house is glazed with panoramic windows, instead of conventional radiators, we install floor convectors - hidden in the floor, a more aesthetic version of radiators.

• Heating with underfloor heating. This option will allow you to more evenly heat the room and to refuse from radiators, which will simplify the arrangement of furniture in the premises.

• Combination of radiators and underfloor heating - this option allows, depending on the type of room, to use the advantages of both types of heating equipment.

To choose the best heating option for your home, you should take into account many factors that influence the formation of the choice of the heating principle and the system diagram:

• The area of the house, the material from which the house is built, the characteristics of its insulation, foundation

• Premises of the house, their layout and features, the number and location of windows and stairs

• Availability of connection to the main gas or power grid (taking into account the available kilowatts), the possibility of installing a gas tank

• Seasonality of residence in the house, the number of residents

• Your preferences regarding heating options, equipment and materials

• Budget for system installation and maintenance

Insulation of the attic floor with sawdust

Sawdust - finely ground wood.

naturalness;
lack of toxic impurities;
light weight;
availability of material.

Attic insulation technology with sawdust

before proceeding with the insulation with sawdust, they need to be prepared. Namely, mix cement and water with sawdust in a ratio of 10: 1: 1.

Pour the attic floor with the ready-made mixture and level it. It is worth noting that sawdust can be used as insulation without using a frame only in a non-residential attic. Otherwise, when walking on the floor, the sawdust will be compressed, and the concrete screed will collapse.

build a cellular structure from a bar. Pour a solution with sawdust into each cell. The advantage of this method is that a sub-floor can be laid over the timber. And the attic will be usable

Attic finishing

Internal work attic decoration start by closing the rafters with materials, which will then become the basis for the application of decorating materials. As a covering of rafters, you can use wood, as well as drywall, gypsum fiber, fiberboard or chipboard.

If you want to quickly finish the attic in relation to the walls, drywall is suitable. It is quite easy to install and also affordable. It is attached either to a steel (wooden) frame, or directly to the truss structure in 1-2 layers using screws.

Painting can be done with special water-based paints that do not smell, dry quickly, do not fade, and they can also be easily washed with various cleaning agents.

If you plan to decorate with wallpaper, then you should carefully choose their pattern or even limit yourself to options without patterns. The fact is that the beveled surface of the attic, as well as the presence of corners, can distort the image. If you want to paste over the ceiling as well, then experts advise you to start with horizontal sections, then only move on to inclined ones, and, finally, to triangular ones. It will be convenient to use latex-based glue in this work - its setting time is no more than half an hour.

Installation of a heating boiler in the attic

Is it generally possible to install heating boilers in the attic and second floor of the house? According to experts, this is not the best option, but in extreme cases, if there is no other way out, you can go for it, observing certain conditions;
Which boiler can be installed above the first floor of the house? With a closed combustion chamber! It is much safer than the traditional one, although it costs half as much. Condensing boilers are suitable in which the combustion chamber is always closed. In this case, there will be no risk of carbon monoxide poisoning, and the room will not cool down during the operation of the boiler;

It's clear about a closed combustion chamber, but still, which boiler is ideal for installation in the attic? Wall gas, up to 30 kW. Such boilers are compact, do not take up little space, they do not need a separate room. The specified capacity will be quite enough to provide heat in a cottage designed for one family, that is, relatively small. The main thing is that the wall can support the weight of the boiler. However, we solve this issue even in frame buildings;

And if the boiler runs on solid or liquid fuel, not gas, can it be installed in the attic? In theory, yes. However, think about how you will service the solid fuel boiler on the top floor? You will have to constantly carry briquettes, coal and firewood up the stairs. Yes, and solid fuel boilers weigh a lot, it will be necessary to strengthen the floors. Liquid fuel boilers make noise and give off an unpleasant odor, so they are categorically not suitable for installation on the upper floors;

What should be the chimney if the boiler is installed in the attic or on the second floor? There may be problems here. In general, the height of the chimney for a gas heating boiler should be at least four meters. Imagine if such a pipe will rise above your roof. This can ruin the look of your home. You can get rid of the need to build such a high chimney if you choose a boiler with a closed combustion chamber, which has a coaxial pipe. For boilers up to 30 kW, which we recommend for installation in attics and second floors, you can lead the chimney directly through the outer wall. In this case, the pipe outlet should be located at a height of 2.5 meters from the ground, but in the case of an attic, this is not a problem. The nearest window from the chimney that goes through the wall must be at least half a meter;

What should be the heating system if the boiler is installed above the first floor? Closed! This is a prerequisite.With an open heating system, when the circulation of liquid in the system occurs naturally, all heating devices are located above the boiler itself. In the case of installation in the attic or second floor, this condition for the normal operation of the heating system cannot be met. Therefore, it becomes mandatory to install a circulation pump, which will become part of a closed home heating system;

Will there be enough natural ventilation for the boiler in the attic? In general, yes. But for greater reliability and safety, experts advise making an unclosed hole 30 centimeters from the floor. An exhaust vent is made under the ceiling. The total area of such ventilation should be at least 200 square centimeters.

We state: a wall-mounted gas boiler with a closed combustion chamber and a circulation pump, in addition, can be safely installed and used in the attic or second floor of a private house. published by econet.ru

Installing a fireplace for heating the attic

Please note that the arrangement of a fireplace is fraught with certain difficulties and peculiarities. First of all, if the fireplace was not provided for by the project of the house, you need to focus on strengthening the floor. The fact is that the mass of a brick fireplace will be quite significant, and during kindling, a mass of fuel will also be added to it. In this regard, for the attic, it is preferable to choose either a lightweight version of the fireplace with light pipes, or to stay on an electric appliance. It is worth noting that the electric fireplace is the easiest and most convenient to use, and it is also much safer.

Attic life under the roof

Usually the attic becomes such a favorite place in the house that there is a desire to spend time in it not only in summer, but also when there is a severe frost outside the windows. Therefore, often the owners of attic houses have a need for heating in the upper part of the house. There are different ways to provide good heating, not forgetting that the attic must already be insulated.

Connection to the heating system of the lower floor

In this case, one system will heat the whole house. If before that the parameters of the pump and the boiler were calculated only for their use on the same floor, the equipment should be replaced with a more powerful one. In the attic from the basic heating system, the necessary components are additionally brought out - pipes and radiators, and in case of air heating - air ducts.

Electrical devices

It is not economical to use old-style electrical appliances due to the high energy consumption, which is not cheap. Modern electric convectors can reduce costs. Their installation is straightforward: you just need to choose a place for the device and connect it to the mains. Energy saving is carried out due to the fact that the convector does not work constantly.

Wall-mounted electric convector for your attic

The owner sets the temperature indicator to which the air should be heated. When the device's sensors record that the temperature has reached this level, the convector switches off until the indicators drop.However, it must be borne in mind that for heating the attic, such a device may need more than one, and this will create an additional load for wiring and increase costs.

Heating by fireplace

Having decided to use this heating option, you need to remember that the weight of the fireplace is not small. Consequently, the floor at its location will have to be strengthened. To reduce the pressure on the floor, it is recommended to use a fireplace with light pipes in the attic.

The fireplace in the attic also performs a decorative function.

You also need to be prepared for the fact that using a fireplace as a heating agent in the attic, you will have to constantly bring heavy fuel to the attic floor and take down its waste, making additional efforts.

Heating system

The method consists in creating a system intended only for heating the attic. This option is suitable for attic conditions, especially if a stove is used to heat the first floor, or it is not possible to connect to the main heating main of the house.

In a heating scheme of this type, the main place is occupied by a boiler that runs on any available fuel. Other elements of the system are pumping equipment, a complex that provides air intake and removal of waste products, pipelines, and the necessary fittings.

The heating boiler in the attic looks pretty good

It is important to decide on the type of circulation. If it is natural, then it is assumed that there is no pump that consumes energy, which is an advantage

But at the same time, this option has many disadvantages, including the increased diameter of the pipelines, the immutable observance of the slopes, certain difficulties in control.

It is most convenient to use a two-pipe scheme in the attic with a pump that provides forced circulation - it will contribute to optimal heat distribution.

Warm floor

This system is based on the property of warm air to rise upward. This way you can make your attic floors truly functional! Heating is carried out due to the uniform distribution of heat transfer components in the floor space. These can be electrical cables or pipes containing heated water.

Cables are installed with any type of coverage. If the floor is wooden, a layer of thermal insulation is placed between the logs, and a mesh with a laid cable is suspended above it. A covering is laid on top. Cable heating is a good option for use in an attic room.

Installation of underfloor heating in the attic

The water method of heating the attic is used less often. This is due to the creation of a large load on the floor. To support the weight of the entire heating system, the ceiling must be concrete. The boiler is used as a source of water. Such a system is more often used for autonomous heating.

Thus, attic owners have the opportunity to choose the appropriate way to maintain heat, which will contribute to the creation of coziness and comfort.

Types of heating attic baths

Based on the budget or personal wishes, heating the attic can be organized in the following ways:

Connection to a common system
... In this case, the boiler and pump will require more power. If the heating was not designed during the construction phase, then the equipment will have to be replaced.
Installing a fireplace
... The construction of a classic structure will have to be abandoned due to its weight. The best options are electric models or fireplace inserts.
Underfloor heating equipment
... Such a system can operate on infrared, water or electric heating. Installed during the construction phase or overhaul.One of the most functional heating methods, since in this case the room heats up evenly around the entire perimeter, and warm air rises from the bottom up.
Autonomous heating
... This method is most popular if heating is planned to be done in an already built attic. It is also used when heating a bath with a traditional stove. It assumes a completely separate heating of the attic room.

To install an autonomous attic heating system, it is necessary to think over not only the project itself, but also to understand the installation of individual elements: a boiler, pumping equipment, radiators, pipelines, fittings (fittings, shut-off valves). It is also important to immediately determine the supply of air and the removal of combustion products.

We heat the attic or how to make heating in a house with an attic correctly

There are two ways to use a country house - to live in it periodically, for example, only in the summer, or permanently. Today we will analyze the second option, in particular, we will focus on projects with an attic floor. In this case, effective heating will also be needed for the attic space, which can be autonomous or connected to the general heating system of the house. Let's consider it in more detail.

In the photo - ways of heating the attic floor

Training

In any case, we first need to properly insulate the attic, otherwise the cost of heating it will be very large. Since the floor is located in direct contact with the roof, it is imperative to carry out work on its thermal insulation.

mineral wool,
polyurethane foam,
polystyrene class G1,
foamed polymers.

Advice: treat the attic insulation with special attention, the better you do it, the more comfortable the living conditions on it will be, and also less money will have to be spent on additional heating. High-quality heating is impossible without proper roof insulation

High-quality heating is impossible without proper roof insulation

Heating system selection

If the house is just being built, it is necessary to provide for the heating of the attic floor at the design stage. However, as construction practice shows, most often the attic is turned into an additional living area after the completion of all work.

In this case, you cannot do without additional costs associated with the wiring of the necessary communications and the choice of the optimal option for heating the room:

underfloor heating system,
installation of a fireplace,
autonomous heating system, the price of which may be different,
connecting the floor to the finished heating system of the house.

What to look for

Whatever you choose, you must first develop a heating system project, in which you try to take into account all the structural features of the building, the need for materials, their cost and quantity.

The heating scheme for a cottage with an attic will make it possible to understand:

where to install the necessary equipment,
how to lay pipes so that you can get the maximum effect from the distribution,
in what place is it better to place ventilation.

General heating scheme for a house with an attic

Feel free to seek professional help to get a safe and effective system. Although, if you have certain abilities and the necessary materials, you can make heating the attic floor with your own hands.

boiler,
circulation pump,
pipelines,
systems of air supply and removal of fuel combustion products.

The heating boiler should be selected depending on the availability and ease of use of certain fuels. Its capacity must correspond to the size of the room. You can calculate them yourself or get them from specialists.

Advice: standard calculation of heating power - 1 kW is required for 10 m 2.In this case, the height of the ceilings is taken to be 2.5-2.7 m.

Stove or fireplace

An excellent option for a heat source in the attic, which can also become an interior decoration. It remains to solve the main question before arranging the fireplace - whether its floors will withstand, since the structure has a significant weight. It may be necessary to carry out work to strengthen them.

Using the fireplace as a heat source

Tip: The load can be reduced by using metal pipes and lightweight refractory bricks.

You can also purchase ready-made cast iron or steel structures. Such fireplace stoves are capable of making a comfortable room temperature up to 200m2.

objects of increased fire hazard,
the arrangement requires the use of non-combustible materials in the interior, correctly installed chimneys and high-quality ventilation.

Advice: to reduce the risk of fire, install structures from walls at some distance or place them in the middle of the room.

Using an electric fireplace requires little maintenance and is safer, although electricity will increase heating costs. To reduce them, you can install convectors that automatically turn off after reaching a certain temperature in the room.

Installation of a steel convector for hot water heating

A house with an attic floor has an excellent appearance and can be used all year round or from time to time. A properly executed heating system allows you to create a comfortable temperature in the room under the roof.

Training

To achieve the desired temperature in the room, first of all, you should take care of eliminating heat loss. Due to the fact that the space is close to the roof, it is necessary to organize the correct insulation of the roof. For this, materials such as foam, mineral wool, polyurethane foam and other foamed polymers are perfect. The higher and better the insulation is performed, the warmer and more comfortable the room will become, which will reduce the cost of heating the whole house.

Whichever option you choose, you should carefully plan the heating scheme, taking into account the specifics of the construction, the amount of materials required and their cost. Such a scrupulous approach will allow you to correctly determine the location of the necessary equipment, taking into account the most efficient placement

pipes

and radiators.

Sometimes, to ensure the correct and safe functioning of heating, the services of specialists are required, but if you have the right materials and certain skills, you can easily do it yourself.

If the building already has a heating scheme, then for heat under the roof, it may be necessary to install more powerful boilers and pumps, a wide range of which is offered by the ALFATEP store, as well as the installation of additional radiators and pipe laying. If the floors are of sufficient strength and the desired design, the pipeline can be hidden in the floor. With air heating, care must be taken to provide auxiliary air ducts.

Autonomous heating

A very effective, albeit somewhat costly, method is the installation of an autonomous boiler unit, due to which a comfortable temperature regime in the room under the roof is ensured all year round. This option is more often used where there is no possibility of connecting to the main heat pipe or when using ovens.

The organization will require a pump, boiler, air ducts for pumping and removing gases. Such a method is good because the cost recovery is quick, and various types of wood, coal, light oil products and gas can be used as fuel. Such efficient and productive solutions will be Kiturami liquid fuel boilers and Plusterm solid fuel units.The capacity of the required equipment is determined by the area, and ALFATEP specialists will help to determine all the calculations and detailed data.

We offer you to familiarize yourself with Pellet consumption for heating

Temperature distributions are carried out by forced and natural circulation. The first method is more efficient, while the second does not require the installation of pumps and additional energy costs.

One of the most effective and modern heating methods is underfloor heating. When organizing such a complex, the air is evenly distributed over the entire area and rises evenly. This solution uses electrical cables or water pipes. The disadvantage of this method is the impossibility of installation in houses without a concrete floor, due to the large weight of such a system.

A fireplace installed in the attic can be an excellent decoration for the attic interior and a reliable source of heat. But before installation, you need to be sure of the strength of the floors or pre-strengthen the place of its location. The load can be reduced by using lightweight types of refractory bricks.

An electric fireplace can be used, which is easier to operate and safer. Here you should take into account the extra energy costs, which can be reduced by installing convectors with special temperature sensors.

You can use:

mineral wool;
polyurethane foam;
G1 class foam;
foamed polymers.

High-quality heating is impossible without proper roof insulation

If the house is just being built, it is necessary to provide for the heating of the attic floor at the design stage. However, as construction practice shows, most often the attic is turned into an additional living area after all the work is completed.

When a heating system has already been installed in the cottage, it may be necessary to install more powerful equipment to heat the attic. In this case, you will need a boiler, a pump, laying additional pipes and connecting radiators.If there are strong floors and design features in the house, the instructions allow for piping under the flooring. In the case of air heating installations, an additional duct system is required.

Autonomous heating method

Convenient, although quite costly method of heating. It makes it possible to maintain a comfortable temperature on the floor at any time of the year. This method is usually used when an attic floor is heated by a stove or when it is impossible to connect to a common system.

circulation pump;
pipelines;
systems of air supply and removal of fuel combustion products.

The heating boiler should be selected depending on the availability and ease of use of certain types of fuel. Its capacity must correspond to the size of the room. You can calculate them yourself or get them from specialists.

"Warm floor"

An efficient and modern heating method. In this case, the heated air rises evenly from below over the entire floor area. The technologies used in the creation of wooden flooring make it possible to conveniently use the system in a country house. You can use electric or water heating. In the latter case, due to its high weight, it is usually used in buildings with concrete floors.

Using an electric fireplace requires little maintenance and is safer, although electricity will increase heating costs. To reduce them, you can install convectors that automatically turn off after reaching a certain temperature in the room.

Installation of a steel convector for hot water heating

Features of the event

Usually, only the ceiling is insulated in a cold attic. Then the roof rafter system is left open so that it is possible to freely inspect it and correct any problems that have arisen. If you insulate the roof with mineral wool, then this already turns out to be an attic, which can be used for a different purpose than an attic.

It is very important that the insulation is done correctly, otherwise condensation will form. If it collects on the ceiling, moisture will seep through the ceilings

Mold and mildew may develop. And the rafters will rot from the inside.

When using mineral wool as insulation, consider its weight. The ceiling, floors must withstand the expected load with a margin, the structure must be reliable.

On the video insulation of the attic floor with mineral wool instructions:

When planning work, make calculations: how much material do you need to purchase? Its amount depends on the area on which the material will be laid and the number of layers. The thickness of the insulating layer depends on the climate of the region.

Step by step instructions

First, prepare the "territory", clear the floor from possible debris, thyrsa. Metal elements of the roof should be painted with oil paint to prevent condensation from accumulating on them.

Then a lining material is laid on the floor as a vapor barrier layer. If it is not there, the mineral wool will absorb all the moisture from the warm humid air that rises from the living rooms.

Over time, it will lose its thermal insulation qualities. A budget option is to use glassine, a vapor barrier film will cost more.You need to lay it with a little overlap, fix the joints (glue it with tape or fix it with wooden slats).

Place mineral wool between the logs tightly, without gaps and crevices. The joints of the material also need to be glued with tape.

Put clean, dry, even boards on top of the logs. They will be the floor in the attic. And the mineral wool will be ventilated, "breathe" under them, dry in case of moisture.

Such installation is sufficient if waterproofing material is laid under the roof and there are no cracks in the attic.

If there is no waterproofing material under the roof, then it is worth covering the heat-insulating mineral insulation with a vapor barrier. The easiest way is to attach the plastic wrap with thin transverse beams.

Minvata is ideal for insulating wooden floors. You can use any kind: in rolls or in plates. Choose the material of the required density, follow the instructions when laying, then the room will be warm and comfortable for a long time.

Types and characteristics

The material is obtained from molten blast-furnace slag, stone (rocks) or glass. In structure, these fibers are thin randomly arranged villi, from 2 to 60 mm long. This insulation is produced in the form of mats or plates. So that the fibers are better adhered to each other, the plates are additionally impregnated with special oil (to repel moisture) and phenol alcohol.

Depending on the origin, they differ:

Glass wool. It is made from a molten mixture of broken glass, sand, limestone, soda. The fibers are 15-50 mm long, and their thickness is 5-15 microns. The material is chemically resistant, hardly flammable (withstands up to +500 o C).

Stone wool. For its manufacture, gabbro-basalt rocks are melted. The thickness of the fibers is 4-12 microns, and they are up to 16 mm long. It heats up, without igniting, up to 300 o C.

Insulation of a cold attic with mineral wool

A vapor barrier is placed under the mineral wool.

To insulate the ceiling of a cold attic with mineral wool, you can take material of any density, from low to high. In this case, it is still preferable to dwell on lighter materials so as not to create additional loads on the beams. Some experts are inclined to believe that glass wool is better suited for insulating an attic with rock wool than stone wool. The latter is too fragile, and its weight is considerable. Also read: "How to choose a heater for walls and ceilings."

As you already understood, the insulation of the cold attic of a private house with mineral wool is carried out by laying thermal insulation between the load-bearing beams directly on the rough ceiling of the first floor. Due to the high hygroscopicity of mineral wool, it is necessary to use a vapor barrier film. In principle, even plain polyethylene can be used. There will be no special loads on the film and with careful installation it will not tear. To be completely sure of the reliability of the protective layer, you need to use a polypropylene vapor barrier reinforced with fiberglass mesh.

Insulation of the attic with mineral wool, technology:

the bearing beams are sewn up from below - this is the rough ceiling of the first floor;
from the side of the attic, a vapor barrier is laid on the rough covering;
mineral wool is placed on top of the film.

The vapor barrier tapes should be overlapped, the joints are glued with double-sided tape. The minvata is placed by surprise so that there are no cold bridges in the places where the insulation is adjacent to the beams.

Thermal insulation of a cold attic with mineral wool is always preceded by calculating the thickness of the thermal insulation. In any case, the layer will be at least 10 cm. Mineral wool is produced with a thickness of 5 cm. It is better to lay the thermal insulation in two layers with an offset of the joints. This will eliminate the possibility of heat loss through the joints of the mineral wool sheets.

After insulating the attic floor with mineral wool, you can immediately lay the floor over the beams.It is advisable to close the insulation with waterproofing before that - a material that does not allow water to pass through, while allowing steam to pass through, but only in one direction

It is important not to confuse which side to lay the waterproofing on, otherwise moisture will accumulate in the mineral wool, as a result of which the thermal conductivity of the material will increase significantly

It is quite possible to use a fireplace to heat a country house. For this, a heat exchanger is built in above the firebox.

Thermal insulation of heating pipes in the basement Pipes and plumbing

House heating costs increase annually. Each owner is looking for ways to save money: the boiler turns on periodically, or constantly works only at a minimum, and so on. The use of such methods leads to a significant decrease in the temperature in the house. But few people think about how efficiently the residential area is heated, because most of the heat is lost on the way to it.

If heat losses can be minimized, then the rooms will warm up better and faster, accordingly, continuous operation of the boiler will not be required, and it will be possible to resort to savings without affecting the temperature. Since boilers are often located in basements and other utility rooms, we will consider how to insulate heating pipes in the basement and other possible places where the system passes.
