Radiation system of heating: calculation, pros and cons, reviews

The construction of a heating system is the most costly item in the capital repair or construction estimate. From the correct installation and features of all elements of this object depend on the operational characteristics, the costs of owners for energy resources in the winter.

постепенно вытесняет устаревающую тройниковую разводку. The radiant heating system gradually displaces the aging tee wiring. This is due to a number of its advantages. How to arrange such a wiring independently, as well as what are its main features, the master should know before starting the installation.

general characteristics

может быть выполнено при помощи различных разводок. Autonomous heating in a private house can be carried out with the aid of various spreaders. The ray system is also called the collector system. Each radiator in the building is fed to the distribution manifold. A separate pipe is delivered to the heating device. To the collector, each of them returns its own pipe. Radiators with this connection are a separate element. They do not depend on other network heaters and are connected to the collector in parallel.

The collector is an overall device. It is responsible for supplying the coolant to each individual circuit. If it is necessary to repair one battery, the heating system continues to operate in the same mode. Only one radiator is cut off.

по тройниковой схеме предполагает меньшее количество труб. Individual heating according to the T-scheme assumes fewer pipes. However, the installation costs pay off during the operation of the system. Particularly pronounced positive economic effect of the use of beam distribution in a large house or cottage with two or more floors.

Advantages and disadvantages

Some features are characterized by the radiation distribution of the heating system. такой организации необходимо рассмотреть перед установкой. Pros and cons of such an organization should be considered before installation. To the disadvantages should be attributed a greater number of pipes and fittings. This significantly increases the cost of repairs. The triple scheme is much less expensive for installation. Also, a large number of connections with improper connection can lead to frequent system failures.

However, all these shortcomings pale against the background of the merits of radiation organization of heating. In this case, the system quickly pays for its installation cost. The ability to regulate heating in each room significantly reduces energy costs. When organizing such a system, there are many joints and drifts. The master has easy access to them. Therefore, during the repair, this factor greatly facilitates the work.

Pipes of the radial system can be hidden under the floor, in the thickness of the wall or just behind the curtains. Correctly planned scheme allows you to remove from the field of view unattractive communications. The tee scheme does not provide such an opportunity to the owners of the house.

Elements of the system

состоит из нескольких обязательных элементов. Radial distribution of the heating system consists of several mandatory elements. The main one is the boiler. When calculating its capacity, consider the area of the premises, as well as the heat loss of the building.

The circuit includes a circulation pump. There are systems with a natural circulation of the coolant. However, they are less effective. Today practically all schemes of radiant heating have a pump in their composition. It causes the heated liquid to move along the contours at a certain speed. So it is possible to maintain the optimal mode of heating the room.

The collector is a distribution unit. He is responsible for the optimal nutrition of all circuits. This element can have in its composition various regulating and closing equipment. The presented devices are installed in a special cabinet. This allows you to protect the equipment and hide it from prying eyes.

Type of circulation

может использовать принцип естественной или принудительной циркуляции. The radiant heating system of a private house can use the principle of natural or forced circulation. In the first case, the coolant is distributed along the pipes and radiators by gravity. This requires the installation of large diameter pipes. This is a simple but less effective system. It is suitable only for a small one-story house, which is not supplied with electricity.

In modern construction, ray systems are used in combination with a pump. It provides forced circulation of the coolant. The pump is mounted on the supply or return circuit. It works with a certain power. Such a device is necessary for the heating system of a large or two-storey cottage.

Due to the mass of advantages, as well as the acceptable cost of circulating pumps, today such an installation option is used almost everywhere.

Design

выполняется еще на стадии проектирования. Calculation of the radiant heating system is carried out at the design stage. For this, a detailed diagram with dimensions must be drawn on paper. It indicates all the elements. If necessary, the drawing can be ordered in a special organization.

First you need to evaluate the existing features of the room. The rooms should not be finished. It is best to hide the pipes in the floor under the screed. Also on the plan are the radiators, their location (on the wall under the window). The number of sections and their internal volume depend on the material of the convector, as well as the thickness of its walls. In accordance with the parameters specified by the manufacturer, the heat carrier volume requirement for each battery is calculated.

по лучевой схеме характеризуется некоторыми дополнительными теплопотерями. Autonomous heating in a private house by the radiation scheme is characterized by some additional heat losses. Heated liquid is supplied to the batteries through pipes, the length of which will be greater than in the trigeminal scheme. This feature must be taken into account in the calculations.

The plan indicates the location of the pipes. To the equipment are added manometers, thermometers, shut-off and regulating armature. Before installation, you should carefully consider all the elements of the main and additional equipment. The sequence of their installation is also indicated in the diagram.

Selecting the collector

имеет в своем составе коллектор (гребенку). Radial heating system includes a collector (comb). This element has the form of a pipe. It has nozzles for the inlet and outlet of the coolant. For the beam scheme, two types of collectors should be installed.

The first of these will be the input comb. A pump is connected to it, as well as a coolant distribution valve. It can be three- or two-way. The valve has a thermometer. It is installed in the reservoir housing. The device transmits information to the valve. It opens or closes the flap, mixing the hot liquid into the circuit.

The output collector collects the cooled coolant, which returns to the boiler. The heater heats up again. Additionally, a balancing flow controller can be installed on this branch pipe. The collector group ensures the stability of the system. It is responsible for the optimization and balance of heating of the coolant in the system.

Pipe Selection

, которое монтируется по лучевой схеме, требует правильного подбора труб. Individual heating , which is mounted on a beam scheme, requires the correct selection of pipes. Communications must be flexible enough to avoid mounting a large number of connections. Best of all for this purpose fit pipes made of cross-linked polyethylene. Such products are sold in bays.

Polyethylene pipes that are suitable for radiant heating systems must have an airtight interlayer. When using conventional varieties, air enters the system. It leads to the development of corrosion of metal elements, the rapid failure of equipment.

To connect the collector to the boiler, ¾-inch pipes are used. To the comb, the radiators can be connected with ½-in. This is possible with the use of a circulating pump in the system. Otherwise, the diameter of the pipes may be larger.

Mounting Features

может быть смонтирована силами владельцев частного дома. The radiant heating system can be mounted by the forces of the owners of a private house. To do this, it is necessary to allocate a separate room for the arrangement of the boiler house.

After installing the heater immediately after it is mounted a comb. The equipment must be in a protective box. The collector must be freely accessible. A manometer and a thermometer are installed at the coolant outlet. Allow to stabilize the pressure in the system crane Maevsky and other safety devices.

Shut-off valves allow, if necessary, to prevent or repair equipment. After installation, the equipment is inspected. If everything is normal, the pipes are poured into the screed.

User Reviews

пользователей о которой представлены в большом количестве, считается сегодня одним из лучших принципов организации коммуникаций, по их мнению. Radiation system of heating, user reviews of which are presented in large numbers, is considered today one of the best principles of the organization of communications, in their opinion. It allows you to reduce the cost of paying for energy in the cold period. The effectiveness of such a scheme will be high if the construction of the house was carried out in accordance with all building codes.

If the owners used high-quality materials for insulation, there are no large heat losses in their house, the collector scheme allows to optimize energy costs. Otherwise, such a system will not be effective. The tangible effect of using such a scheme is determined in large or two-story houses.

а также особенности ее организации, каждый владелец частного дома сможет обустроить подобную схему самостоятельно. Having considered what the radiant heating system is, and also the peculiarities of its organization, each owner of a private house will be able to arrange such a scheme on his own.
