Heating scheme of a two-story building. High-quality heating scheme in a two-story house. Pipes for heating

Thermal insulation is necessary in all cases where it is necessary to protect pipes from a decrease in ambient temperature. In areas with a predominantly cold climate, insulation of open sections of the pipeline is a necessary condition for their long-term uninterrupted operation. In air conditioning systems, on the contrary, it is necessary to minimize the heating of air and fluid. The insulation for pipes "Energoflex" will perfectly cope with these tasks.

Insulation features

Thermal insulation for pipes "Energoflex" is a flexible thermal insulator that can be used to insulate not only pipelines, but also various surfaces.

Tubes "Energoflex" by extrusion followed by foaming with butane-propane are made from high-pressure polyethylene (LDPE). The technological scheme of production determines the appearance of the finished product: it is an elastic tube with many air-filled pores. It is precisely due to the presence of micropores that the insulation of Energoflex pipelines has excellent heat-insulating properties.

Thermal insulation "Energoflex" is produced in the form of:

hollow tubes put on top of the pipes. The diameter of the products is in the range of 18-160 mm. Depending on whether a new pipeline is being installed or an existing one is being insulated, Energoflex insulation for pipes can be put on in its entirety or cut along and glued along the seam after installation.
Rolls– foiled or without foil. Such a heat insulator can both cover floors and wrap complex or hard-to-reach heating or water supply systems.
Sheets. Flexible thermal insulator plates are used to ensure the operation of fittings or pipeline sections with very large pipe sections.
Plates. Products are used for thermal insulation of floors and large areas of communications. Energoflex boards can only consist of foamed polyethylene or include a layer of foil (read also: “How to choose insulation for pipes made of foamed polyethylene - characteristics of the insulating material”). In the latter case, in addition to maintaining heat, water-repellent properties of the material are provided.

It produces Energoflex and self-adhesive tape for joining and final sealing of insulating materials.

Of course, the entire range of products offered by the company has quality certificates and meets safety requirements. Today, Energoflex pipe insulation is the best choice for home and industrial use.

Properties of heaters "Energoflex"

The properties of high-density polyethylene foam make it possible to use the products in almost any conditions, except for being under direct sunlight.

Technical characteristics of the insulation for pipes "Energoflex":

high quality organic thermal insulation - indicators in the region of 0.038-0.039 W / (m s);
range of permissible temperatures confirmed by certification – from -60°С to +90°С;
resistance to chemicals of almost any nature - high pressure polyethylene does not react with alkalis, acids, salt solutions and oils, protecting pipes from corrosion;
good water-repellent properties - absorbs no more than 3.5% of the volume of moisture;
service life with proper installation and use - up to 25 years;
an impressive size range of pipe products and an unlimited scope of Energoflex rolls.

Among the shortcomings of the heater can be noted:

instability to direct solar radiation;
low mechanical resistance - up to 0.3 MPa;
the upper temperature limit - +100°C - limits the scope of products.

Insulation installation

Due to the flexibility and low weight of the material, the installation of insulation is quick and without much physical effort. The only limitation is that the work must be done at a positive air temperature so that the glue does not harden.

The order of installation of thermal insulation:

Clean and degrease the surfaces of the pipeline on which it is planned to place the insulation.
Carefully lay the thermal insulator, leaving no bare sections of the pipe.
First, bent sections and fittings should be isolated, then straight sections of the pipeline.
To connect the parts, a special glue is applied to the surface.
The assembled thermal insulation should dry out within a day, after which the system is ready for operation.

If everything is done carefully and in accordance with the instructions, thermal insulation will last a long time, preventing unnecessary heat transfer and protecting pipes from corrosion.

Overview of thermal insulation Energoflex for pipes

Thermal insulation, as well as the installation of a shell for thermal insulation of pipes, is a necessary measure for the normal operation of the pipeline, which ensures the protection of pipes from freezing under the influence of negative temperatures in winter, and from loss of coolant temperature as a result of heat exchange with the environment in the rest of the year.

Thermal insulation for pipes Energoflex

This article will consider one of the best materials for thermal insulation of pipes - Energoflex. You will find out what strengths and weaknesses this material has, as well as get acquainted with the types of insulation, and their technical characteristics.

1 Advantages and disadvantages

Energoflex polyethylene foam has all the strengths and weaknesses of this material. First of all, it is necessary to highlight the complete resistance of the insulation to the liquid, which has a positive effect on the durability of the pipes, since they receive reliable protection against corrosion due to moisture.

This advantage is explained by the fact that tubular thermal insulation from Energoflex, like polyurethane insulation, has a structure of many closed cells that do not let water or steam through.

When completely immersed in liquid for 24 hours, the insulation absorbs no more than 0.5 of its volume of water, and then only cells on the outer surface of the material absorb liquid, which were cut when cutting sheets of foamed polyethylene when creating insulation sleeves.

The advantages of this material also include low thermal conductivity, which is 0.032 W / mk, which is comparable to more expensive mineral wool, which is considered one of the best existing heat insulators.

According to the flammability class, Energoflex belongs to the G2 group - normally combustible materials, the operating temperature range of the material is from -40 to +90 degrees. The ignition temperature of the material is 306 degrees.

The manufacturer adds special additives to the composition of polyethylene, thanks to which Energoflex insulation has the ability to freeze-out, in the absence of direct exposure to fire.

Tubular thermal insulation Energoflex, like thermal insulation K-Flex for pipes, is sufficiently elastic, which allows it to take its original shape after any deformation, and guarantees maximum ease of installation on pipes of any shape.

Pipes insulated with Energoflex

Among the other advantages of Energoflex, the following factors can be distinguished:

Resistance to chemically aggressive environments, which makes it possible to insulate underground sewer pipes that are constantly in contact with groundwater;
High strength characteristics that guarantee a long service life of the insulation - from 20 to 25 years, during which the material does not rot and does not lose its thermal insulation properties;
Environmentally friendly as a heater for pipes made of foamed polyethylene - when working with Energoflex, there is no need to use any protective equipment, since foamed polyethylene does not have any negative effect on the human body.

1.4 Energoflex Black Star Split

Energoflex Black Star Split differs from the standard Black Star in that this material is intended for thermal insulation of air conditioning pipes located outside buildings.

This feature requires increased strength characteristics from the insulation, both in terms of resistance to mechanical stress and atmospheric influences.

To obtain the above properties, the manufacturer uses a special polymer coating that is applied over polyethylene foam. This coating guarantees effective protection not only against physical damage, but also against UV radiation.

Moreover, the polymer layer reduces the flammability of the insulation - Black Star Split belongs to class G1 (low combustible materials).

In terms of technical characteristics, this insulation is completely similar to Black Star thermal insulation.

1.5 Energoflex Brek Star Duct and Duct AL

Energoflex heaters from the Dact line are intended for thermal insulation of ventilation ducts, air ducts and similar large-diameter pipes.

Roll insulation Energoflex Dakt

Dakt heaters are produced in the form of rolls with a width of 120 centimeters. The length of the rolls can be 5, 7, 10, 20, and 30 running meters.

Black Star Duct has a self-adhesive surface, which makes the installation of insulation on air ducts of any shape extremely simple and fast. The coefficient of adhesion of the self-adhesive layer to metal surfaces is 600 g/cm - not every material has such characteristics.

In addition to thermal insulation properties, Black Star Duct has the ability to reduce noise, thanks to which the material is able to drown out the rumble of air transported through the ventilation system.

A feature of the Energoflex Dact AL insulation is the presence of an aluminum layer that performs a shielding effect.

The ability of the insulation to reflect heat guarantees the most effective thermal insulation of air ducts even under the most severe working conditions - these materials perform well even at the lowest possible temperatures, down to -40 degrees.

Energoflex insulation for pipes: types and features of the material, installation tips

Energoflex for pipes is a modern heat-insulating material produced by the Russian company ROLS ISOMARKET. When buying a heat insulator, it is important to correctly

Before every homeowner who has decided to make the right heating in his two-story house, the question of choosing the type of system initially arises. There are several options for traditional and new schemes, but in order to choose one of them, you need to understand the essence of the issue a little. The purpose of this article is precisely to consider what the heating scheme of a two-story house is, to reveal the pros and cons of each type of system.

Single pipe or double pipe?

As the name implies, these systems differ in the number of main pipelines that supply the coolant to the radiators. In a single-pipe scheme, all battery connections are connected to one common pipeline, which is both supply and return. A striking example of such a system is the famous "Leningrad", shown below in the figure:

With the apparent ease of installation and savings in materials, a single-pipe system has one serious drawback. Since each battery discharges cooled water into a common line, the coolant comes to the next radiator with a lower temperature, and so on, until the end of the branch. Because of this, the very last heater may be barely warm. What does it mean?

The room still needs to be heated, which means that you will have to increase the heat transfer of the battery, that is, increase the number of sections. It turns out that we saved on pipes and fittings, but spent money on additional sections. Add to this the difficulties with regulation in two-story houses and the impossibility of natural circulation.

The disadvantage of a two-pipe system is only that more materials are needed to assemble it, since in this case the supply and return manifolds are separated. That is, the coolant comes to all batteries through one pipe, and leaves through another. This scheme of the heating system of a private house has many advantages, and therefore is the most popular. This is a reason to opt for a two-pipe system.

Types of two-pipe systems

Currently, the following types of two-pipe schemes are used in private housing construction:

with natural circulation;
with forced circulation;
collector system;
scheme with a double-circuit boiler.

Each of the above systems has its own characteristics, advantages and disadvantages that determine its scope. Consider all the schemes in order and reveal their features.

Natural circulation system

The principle of its operation is based on the convective movement of water. The hot coolant leaving the boiler has a lower density and weight than the cooled water coming through the return line. The latter tends to sink down and displace the lighter heated coolant. Due to this, natural circulation occurs. For the normal operation of the system, several conditions must be met:

due to the low velocity of the liquid, the diameters of the pipes must be increased to ensure the necessary flow of the coolant;
the difference in densities and masses of water with different temperatures is small, therefore, a heating circuit with natural circulation should be mounted with large slopes of horizontal sections;
the pipeline network is under natural pressure, it is unacceptable to create excess pressure, otherwise the flow of fluid will stop. This means that the expansion tank can only be of an open type and must be installed above the entire system;
to withstand all slopes, the boiler often has to be placed in a small depression.

What does such a heating distribution scheme give us in a two-story house, where compliance with all conditions requires careful calculations and leads to a large consumption of materials and installation complexity? The answer is simple: the gravitational circuit, which functions in conjunction with a conventional solid fuel or gas boiler, makes the water heating of a two-story house independent of electricity. Sometimes this is a very important factor, for example, in areas with unreliable electricity supply. This is the scope of gravity systems.

Forced circulation system

Here, the movement of the coolant through the pipeline network occurs due to the operation of the circulation pump, which creates excess pressure in it. The introduction of a pumping device into the circuit made it possible to achieve the following advantages:

reduction of pipe diameters. The fluid flow rate has increased, and now a smaller flow area of pipes can be used to ensure the required flow;
improving work efficiency. If the forced circulation heating scheme is designed correctly, then high-temperature water will successfully reach both the nearest and the farthest radiators;
pipes can be laid in the most convenient way, which plays a huge role in interior design issues. The lion's share of highways can be hidden using boxes or floor and wall structures;
convenience and comfort in use. The fact is that forced circulation makes it possible to implement any projects to automate maintaining the climate in the house;
economy in energy consumption. The conclusion follows from the previous paragraph, since automation allows you to heat the premises according to the daily schedule at a time when there are people there;
the system is easily adjustable.

Note. In two-story houses where the old scheme with natural circulation is involved, you can always put a pump. This modernization will make it possible to realize, if not all, then the main advantages of the pressure system.

Installation of a circuit with artificial inducement is laborious, but relatively simple, it can be easily done by hand. Take at least an expansion tank of a membrane type, which does not need to be placed in the attic, and even control the water level, as with gravity. Its place is in the furnace room, near the boiler.

The most significant drawback of the circuit is its volatility. One has only to turn off the two-story house from the electricity, and after a while the heat in the rooms is gone. The ways to eliminate the disadvantage, although simple, are costly: the purchase and use of an electric generator or, at worst, an uninterruptible power supply.

As for the allegedly high cost of materials, we have already discussed this issue, speaking of a one-pipe system. Although it should be noted that the cost depends on the number of control valves and automation tools included in the heating project. In the budget version, the assembly of the circuit will cost a little more than a single-pipe one.

Collector heating system

This is one of the new trends in the field of heating private houses, which appeared relatively recently and originated from two-pipe pressure systems. Only in contrast to them, the collector heating system of a two-story house has many branches converging to one center - the distribution manifold. The circuit resembles a set of rays diverging in all directions, with a distributor inside, as shown in the figure:

As you can see, the radiant heating system provides for a separate connection of each radiator to a manifold directly connected to the boiler. In this case, the "beams" are completely hidden in the floor structure, and the distributor is built into the wall inside a special cabinet. Only the connections to the batteries remain in sight, and even a branch coming from the boiler.

It is unnecessary to convince someone that the collector heating scheme in a two-story dwelling is the most efficient of all. Each radiator is powered separately, they do not affect each other. Adjustment and automation can be implemented in any way. The rosy picture is spoiled by only one circumstance - the high cost. This fact is also well understood at one glance at the diagram. There is also a disadvantage that has been inherited - dependence on electricity.

Heating scheme with a double-circuit boiler

In fact, the heating scheme of a two-story house with a double-circuit boiler is no different from a conventional two-pipe system. The problem is somewhat far-fetched and its solution does not depend on heating networks in any way. The crux of the matter is that the double-circuit boiler is disconnected from the system during water heating and is exclusively engaged in hot water supply. If it takes a long time, then the building starts to cool down and it becomes cool inside.

A similar situation is a consequence of an incorrect selection of the boiler power, the installation of heating has nothing to do with it. The power of the heat generator should be determined taking into account the heating of water at the DHW. If this has not been done and the boiler has already been installed, then there is only one way out - to reduce the temperature of water heating and use it sparingly.

What is the best heating system for a two-story house?

The answer to the question depends on individual conditions and wishes. If you want not to depend on electricity, you will have to make a gravity system with all its shortcomings. When there is a desire and opportunity to build an efficient and economical scheme, then a system with a collector connection is at your service.

In practice, heating distribution in two-story houses is most often two-pipe with forced circulation. In terms of cost and efficiency, this is the best solution, it allows you to realize a lot of opportunities and economically heat your home, incurring costs of medium size. And for self-assembly, this scheme is quite convenient.
