Correct installation of heating radiators in a private house. DIY heating radiator installation

Knowledge of the nuances of competently carrying out the process of installing heating radiators will provide reliable, high-quality and durable heating premises.

At self-assembly batteries, it is important to follow the installation rules and SNiP norms.

General rules for self-installation of batteries

Applicable to all batteries, regardless of type:

• necessarily produced calculation of the amount of coolant that the battery can hold;
• water in the heating system overlaps, then using a pump, the pipes are blown;
• availability is required torque wrenches;

Attention! Tighten and secure parts at your own discretion unacceptable! The circulating fluid is under pressure, so improper fastening of the parts leads to unpleasant consequences.

• initially thought out and selected suitable connection option batteries;
• radiators are mounted at a certain angle to prevent the accumulation of air masses in them, otherwise they will have to be removed through the air vent;
• in private houses, pipes from metal-plastic, in apartments - from metal;
• protective film only remove from new heating devices after the end of the installation.

Stages of installing a heating radiator in an apartment with your own hands

Installation consists of the following steps.

Instrument preparation

You will need:

Choosing the right place

• location heater selected in the center of the window opening;

Important! The battery must cover not less than 70% of the opening. The middle is marked, and from it the lengths are laid to the right and left and marks are made for the fasteners.

• clearance from the floor not less than 8 cm and not more than 14 cm;
• to exclude the sinking of the thermal power indicator, the battery must be located from the windowsill at a distance about 11 cm;
• from the rear wall of the radiator to the wall not less than 5 cm, this distance will provide good heat convection.

More precise margins are calculated with the perfect choice of a specific type of battery and the calculation of the number of sections.

Preparing to connect

Examine the walls for possible defects. If there gaps and slots, they are laid cement mortar ... After drying, fix the foil insulation.

The variety of wall decoration options is quite extensive.

Choosing a wiring diagram

Exist 3 connection options radiators to the heating system:

• bottom way, fastening is made at the bottom of the heating source, on its different sides;
• lateral (one-sided) connection, most often used with a vertical type of wiring with entry into one of the sides of the battery;
• diagonal connection implies the location of the supply pipe on top of the battery, and the return pipe on the opposite side from the bottom.

Subsequence:

Reference! At this stage, as an additional element, you can install thermostats, allowing you to control the flow rate of the coolant.

• fixing the radiator on brackets;
• accession outlet and supply pipes performed by threading, welding, pressing and crimping;
• the control assembled system: water is supplied under low pressure to check for possible leaks and assembly flaws.

How to properly install different types of radiators

The installation of each type of battery has its own nuances.

Cast iron

The difference from the standard circuit is that for batteries of this type the sections are initially formed using a radiator key.

Nipples are impregnated with linseed oil and fixed by hand for 2 threads... In this case, a gasket is necessarily used. Then the radiator keys are inserted into the nipple holes and tightened.

Important! The collection of sections must be carried out with an assistant, since simultaneous rotation of nipples can lead to skewing.

After crimping the battery, a layer of primer is applied to it and painted.

Aluminum

Passes according to the standard scheme of one of three options connections.

The only caveat is aluminum batteries fixed both on the wall and on the floor. For the latter option, use special clamping rings on legs.

By adjusting the indentation of the radiator from the wall, floor and window sill, you can increase or decrease the level of heat transfer from the battery.

When installing aluminum heating sources are guided by the attached instructions. If the recommendations indicate the use of a coolant, then it is necessary to use it exclusively.

Mounting the screen in front of the radiator will increase the degree of efficiency.

Such batteries are suitable for installation in private houses with autonomous heating.

Steel

An important point in connection - horizontal check batteries. Any deviation will reduce work efficiency.

In addition to wall brackets, floor stands for additional fixation.

Otherwise, standard connection schemes are used.

Bimetallic

In such batteries, it is allowed building or removing unnecessary sections. They are already painted. The sections are pulled together in stages from the bottom and from the top, without distortions.

Attention! In the place where the gasket under the nipple is located, do not clean sandpaper or file.

As with the standard scheme, it requires Preliminary processing walls.

The need for a competent installation of heating radiators arises both when replacing a single device and when installing the entire system. Exactly last option it is reasonable to consider in detail and in detail.

The heating season in our country lasts at least six months, so a lot depends on the heat circulation system: not only the comfort of living quarters, but also human health, the cost of heating and the relevance of its repair. Consider the main schemes for supplying heat to apartments and residential buildings:

• Cast iron radiators. Massive classic appliances, "guests from the past". They are used on a leftover basis and are no longer produced by modern industry. They are characterized by low heat transfer and appearance, which has to be decorated - curtains, slats, etc. Which further reduces the circulation of warm air in the room;
• Sectional type aluminum radiators. Lightweight, reliable and efficient devices for the heating system. Approximately 50% of the energy of the coolant falls on convection into the room (for cast-iron counterparts, this figure barely reaches 25%). Equipped with convenient pressure / flow regulators and attractive design;
• Steel sectional radiators appearance very similar to aluminum ones - but at the same time much more massive and somewhat more expensive in price terms. The main advantage of the steel heater circuit is its high resistance to corrosion. If the water in the heating system is hard, contains acidic or alkaline impurities, it is wise to choose such batteries. Installation steel radiators heating should take into account their significant weight;
• Bimetallic radiators - have the best performance characteristics and the highest cost (about 20% higher than aluminum sections) Withstand high pressure in the system, operate in the range from 20 to 40 atmospheres. All other types described above can function at a water pressure in the system of 15-25 atmospheres.

Standard service life bimetallic radiators is up to 25 years, steel and aluminum - at least 20 years. In reality, they can last up to half a century. Of course, under the obvious condition - if the system is selected and connected correctly.

When replacing a single heater (for example, cast iron sections are leaking), it is important to pay attention to the center distance, hole diameter and thread pitch. It is best to measure these parameters with a tape measure and a caliper. There are many types of heating devices on the market and in stores, their design features differ from each other. You can purchase a device that looks like a failed battery - but it will not work when installed.

When the entire system is changed, or the heating is installed again (for example, in a new house or apartment), a correctly drawn up project is important:

• As pipes - direct and reverse - it is best to choose plastic with a metal layer used for hot water supply. In the specifications, the permissible water temperature must exceed the temperature in the system by at least 10 ˚C;
• The best places to install the selected heating radiators are under windows or on one side of long blank walls. This ensures the best circulation of warm air in the apartment / house;
  
• The sectional arrangement of the batteries allows you to vary their length, and therefore, the power of the heating system. Correct connection provides for the presence of 6 (minimum) to 15 (maximum) sections for one radiator;
• Average standard for 1 square meter of the heated room is 0.7–1.1 sections of aluminum, steel or bimetal. Installation is recommended in rooms with an area of ​​more than 15–20 m 2;
• In addition to the main pipes and the batteries themselves, you should stock up on the required number of connecting fittings, corners, brackets and other accessories. To drill holes in ceilings and walls, you will need a perforator with a long drill and a special "iron" for welding PVC pipes.
  

Of course, all the batteries to be installed must be of the same company (and preferably from the same batch). Similar requirements apply to the piping system. How to install a heating radiator and connect it after installation, we will consider in more detail.

The site masters have prepared a special calculator for you. You can easily calculate the required number of sections.

Installation and connection of radiators - step by step instructions

The installation of new heating radiators should be divided into several stages:

How to install and connect heating radiators with your own hands - a step by step diagram

Step 1: Batteries come first!

When installing radiators on a wall, the first thing to do is to install the batteries. This is done on two (with more than 10 sections - three) brackets, pre-hammered into the wall. Water inlet and outlet pipes are protected with special plugs. It is important to accurately align each radiator both horizontally and against the wall. This will not only give the entire system an attractive design, but will also increase the service life of the heating circuit.

The brackets must be able to withstand heavy loads. They are buried into the wall by at least 10 cm. The backlash and vibration of the brackets should be minimal (a few millimeters 20 cm from the wall).

Step 2: Well, pipes - only later

Some new homes have special holes in the floor slabs for piping systems. If these holes are not there, they are punched with a puncher, with a double margin of diameter. For example, for two pipes with a diameter of 20 mm, a common hole of at least 50 mm is punched. Pipe cutting is performed with a grinder, with a small amount of work - with a hacksaw.

The location of pipeline schemes strictly vertically is a condition for their long-term and trouble-free service. First, the entire riser is welded with an "iron", then it is attached to the wall with special clamps. We use a level and a perforator (as with the heating radiators themselves). Further, the branches are made to the batteries themselves.

In the old days, it was problematic to install heating radiators on your own because of the welding work, which was an integral part of the installation. Modern materials allow you to do without special devices, which makes it possible to install heating radiators in the house with your own hands.

To carry out similar events in the apartment, it is recommended to involve plumbers of the service company, since it will be necessary to completely disconnect the system from the mains and drain the water. Not everyone knows how to do it correctly, and a poor-quality connection can turn into a flood hot water.

Determining the location of radiators

If we are talking about replacing old structures with new ones, then the question of location disappears by itself. In the case of planning a circuit diagram, it is necessary to take into account important factors, according to which the batteries must create reliable thermal protection. No matter how high-quality modern double-glazed windows are, they are still sources of a cold air stream. That is why batteries are installed in almost all rooms below the window. But it should be borne in mind that the radiator must cover at least 70% of the window opening. Only then will its functioning be effective.

- the distance from the window sill to the top of the heater should be within 9-14 cm;

- from the bottom of the battery to the floor, a gap of 7-12 cm is required;

- leave a distance of 3-5 cm between the radiator and the wall;

- place the heating structure in the center of the window opening.

Based on the listed requirements, we can summarize that the installation site should precede the choice of the model. Only in the presence of certain parameters, the power and equipment of the sections are selected.

Radiator connection options

The diagonal method involves connecting the supply pipe to the upper part of the heater, and the return from the bottom, but with the location on the other side;

The bottom connection is carried out at the bottom of the battery on opposite sides;

The side or one-sided method is more often used with a vertical wiring diagram with a connection to the right or left side of the radiator.

Stages of installing heating radiators with your own hands

1. Preparatory work includes the dismantling of old structures, if necessary. The water must be completely drained from the disconnected system beforehand. On the wall, you will need to install special fasteners for the batteries or check the strength and correct installation of existing hooks. You should also do a study of the wall surface for integrity. Often, cracks and gaps form under the windowsill over time. They must be sealed with cement mortar, and foil insulation should be fixed on a dry surface. Among other options for wall decoration: plaster with a special insulating compound, plasterboard cladding with an insulating layer, etc.

2. The complete set of the radiator includes: installation of an air vent, screwing the plugs into the unoccupied openings of the collectors. If the diameters of pipes and collectors do not match, the connection is made using adapters.

3. Next, the shut-off and control valves are installed. To do this, at all inputs and outputs are placed Ball Valves... They will allow subsequent repairs to be carried out without completely shutting down the heating system. Thermostats do not belong to required elements, but their use saves the consumption of the coolant on warm days. Therefore, regarding additional devices, each owner makes a decision independently.

4. When hanging radiators on mounts, it is recommended not to remove the protective film from new models. It will protect the surface of the batteries from contamination until finishing work is completed.

5. The connection of the supply pipe and the outlet pipe is made sequentially by one of the existing methods: threaded, crimp, press, by welding.

6. The next step is pressure testing. Water into the system should be opened at a low pressure, a sudden start can provoke a water hammer, as a result of which the shut-off valves will fail.

To increase heat transfer and save heat resources, it is worth fixing a sheet of foil insulation on the wall on the back of the radiator. Penny costs will save up to 10% on heating.

Are you planning to change the heating appliances in your own home? For this, knowledge about the types of battery wiring, how to connect and place them will come in handy. Agree, because its efficiency directly depends on the correctness of the selected scheme for connecting heating radiators in a particular house or room.

Correct connection of the batteries is a very important task, because it is able to provide a comfortable temperature in all rooms at any time of the year. It's good when the fuel consumption is minimal, and the house is warm on the coldest days.

We'll help you figure out what it takes to get the most out of your radiators. In the article you will find many useful information on the methods of connecting batteries and on their implementation without the involvement of specialists. There are diagrams and videos that will help you clearly understand the essence of the issue.

An efficient system heating is able to save money on fuel bills. Therefore, when designing it, you should make a balanced decision. Indeed, sometimes the advice of a neighbor in the country or a friend who recommends such a system as his is not at all suitable.

It happens that there is no time to deal with these issues yourself. In this case, it is better to contact professionals who have been working in this field for over 5 years and have grateful reviews.

The first option involves the use of physical laws without buying and installing additional devices. Suitable when water acts as a coolant. Any non-freeze will make it worse to circulate through the system.

The system consists of a boiler that heats water, an expansion tank, supply and return pipelines, batteries. The water, heating up, expands and begins its movement along the riser, visiting in turn installed radiators... The cooled water from the system goes back to the boiler by gravity.

With this type of circulation, the horizontal pipeline is installed with a slight slope towards the direction of movement of the coolant. This system is self-regulating, because depending on the temperature of the water, its quantity also changes. The circulation head is increased, allowing the water to heat the room evenly.

With natural circulation, two-pipe and one-pipe schemes with an upper wiring are used, two-pipe with a lower one. Such methods of connecting radiators to the heating system are beneficial to use for small rooms.

It is important to equip the batteries with air drains to remove excess air or install automatic air vents on the risers. It is best to locate the boiler in a basement, so that it is lower than the heated room.

For houses with an area of ​​100 m 2 or more, the coolant circulation system will have to be changed. In this case, you will need a special device that stimulates the movement of water or antifreeze through the pipes. We are talking about . Its power depends on the area of ​​the heated room. The use of a pump for forced circulation allows the use of antifreeze as a heat carrier. In this case, you need to install a closed-type expansion tank so that the fumes do not harm the health of the inhabitants of the house.

The circulation pump is used in two- and one-pipe circuits with horizontal and vertical heating devices connection system.

In order for the installation of heating radiators to be completed as quickly and efficiently as possible, it is most rational to involve specialists in this. However, there are situations when the cost of services announced by professionals is clearly not affordable for the customer. And what to do in this case? Looking for cheaper workers, whose services are more affordable? But in a number of cases, the quality of the work performed by them is highly questionable. And then any customer comes to a logical decision - to install heating radiators on their own. It's doable. The main thing is to do everything carefully, having previously familiarized yourself with the simple rules and snip.

Installation of heating radiators

General description of the process of installing radiators

How to install a heating radiator correctly? The process of installing radiators is not as complicated as most of us imagine. More precisely, it can be difficult if the radiators themselves "try". Therefore, before deciding on any model, it is important to familiarize yourself with the rules for its installation. For example, any person, even if not a professional, will be able to perform an operation such as installing a heating radiator made of aluminum, since they do not require skills in use. additional equipment... However, the same cannot be said about cast iron radiators - in order to install them, you will have to master the rules for using a welding machine.

Before purchasing radiators, you should take a close look at the models available on the market.

In addition, it will not be superfluous to determine for yourself what exactly the characteristics of the radiators you need will be according to the following criteria:

• wear resistance;
• profitability;
• flowing;
• resistance to the environment.

And if you correctly determine these parameters and are able to select the appropriate radiators, then heating system in your home will delight you with warmth for many years. A significant role is played not only by the installation diagram of the heating batteries, but also by the material from which the radiators are made. The fact is that many modern models, made of ultra high quality and environmentally friendly materials, have exorbitant prices. Therefore, try to be realistic about your capabilities and needs. Hardly in country house you may need extra expensive batteries.

When self-installing heating radiators, you should be extremely careful and accurate.

In particular, when installing, you should take into account such parameters as the height of the radiator relative to the floor, the distance between the wall and the radiator. To a lesser extent, which wall the battery will be attached to - most modern models easily mounted on walls covered with plasterboard. However, remembering the characteristics that you should rely on is quite simple - the distance from the floor to the lowest point of the battery should not be less than 5 cm.The same distance (at least 5 cm) should be between the wall and back wall radiator.

It is very simple to carry out such an operation as installing heating batteries yourself. If you have never dealt with any such work before, then the necessary information and the complete installation process can be found on our website, where instructions and video materials are presented. In addition, today there is a large number of specialized forums and resources where professional masters share tips and show the optimal installation schemes for heating radiators. And, using the information from such a site, you can easily find out how to properly install the heating battery yourself.

Installation tools

If you've never practiced before renovation works and did not install radiators, it can be assumed that you hardly have the necessary set of tools. However, this does not mean that you absolutely need to run to the store and buy everything. Firstly, it is quite expensive, and secondly, it may not be useful to you in the future.

Therefore, the most rational thing to do before installing the heating battery is to simply ask around from friends - perhaps someone has what you need.

So, for the installation of radiators, you will need: an impact drill and a drill with a victorious tip, a screwdriver, pliers, a building level.

A little trick - when purchasing heating radiators, check in advance that all the elements are assembled. If this is not the case, ask the store to collect everything for you - this way you do not have to purchase an expensive and unnecessary key in the future.

How to choose the right size batteries

Before purchasing batteries, you need to correctly calculate what size they should be - how many sections they should consist of. Quite a lot depends on this, including the installation diagram of heating radiators. After all, an insufficient number of sections will not allow the room to warm up, and an excessive number will simply be installed in vain.

The size of the batteries is calculated according to a very simple formula - 1 kW of radiator power is needed per 1 m 2. In some cases, the power indicator must be multiplied by a safety factor of 1.3. This is done when the room has two external walls or there is more than 1 window.

Installing radiators

Such a process as the installation and installation of heating radiators can be divided into several points. First of all, it is necessary to correctly pack all the blanks, American women, Mayevsky crane. Further, if necessary, the old radiator is dismantled. If, along with the replacement of radiators, the heating element is also replaced, it is necessary to first remove the water from the system. To do this, turn off the water and use the pump to try to drain the water as much as possible.

The finished battery must be installed on the wall. The number of fasteners directly depends on the type of radiator and the principle of its installation.

If you plan to install cast iron heating radiators that will be welded into the system, then only two fasteners are enough. But if the radiator is connected to the system using polypropylene pipes, then there must be at least three fasteners. If the battery is small - 5-6 sections, then the fasteners should be positioned in this way - 2 on top and one on the bottom. If the number of sections is 10 or more, then there should be more fasteners: at least 3 in the upper part, and 2 in the lower part.

Using the building level, we determine the correct location of the battery. Next, you need to designate the places in which plastic pipe will connect with metal. After that, you need to wind up all the elements. It is important to pay special attention to the quality and tightness of the connections. If there is even the slightest error, expect a leak. To prevent this from happening, use torque wrenches of the required size. Be extremely careful - if you install bimetallic or aluminum radiators, carefully turn on the valve through which the air will bleed. A force above 12 kg cannot be applied to it. In order to tighten this valve correctly, torque wrenches will come in handy.

Features of the installation of cast iron radiators

Despite the fact that there are a huge number of types of batteries on the market today, many of us, when planning how to supply a heating radiator, ignore the new bimetallic and aluminum radiators, preferring the good old cast iron models.

Few people take into account that the installation of cast iron heating batteries is a more laborious and complex process.

However, the result is worth the time and effort spent. When installing, you should pay attention to the following factors:

• Before installing a cast iron radiator, it is necessary to adjust the nipples. To do this, the radiator is untwisted, the nipples are adjustable, after which everything is assembled back. The radiator is now ready for installation. It should be noted that disassembly must be carried out using special keys on the radiator workbench. In this case, it is advisable to unscrew both nipples at the same time - this way it will be possible to avoid skewing. Of course, it is most convenient to perform this action together. Pay attention - from different sides of the radiator the threads are directed in different directions. After the nipples are unscrewed - remove the section.
• All sections of the radiators are removed in this way. Next, we assemble the sections in strictly reverse order. The assembled radiator requires pressure testing - this way you can identify if there is a leak. And if it is, readjust the nipple.

• In brick and foam concrete houses cast iron radiators are mounted on special supports in the wall without any problems. But in the event that the battery is attached to a wooden wall, in addition to the standard supports, you also need floor supports.
• If the heating system is a one-pipe system, a bypass must be installed. In addition, the system must also have a Mayevsky crane, as well as shut-off valves.
• To connect the radiator to the pipeline, it is necessary to use threaded squeegees. It is important to remember that in no case is it recommended to use the welding machine in a house with wooden walls.

Of course, it is a private matter for each owner to independently install heating radiators in an apartment, or still entrust it to professionals. Many go to the installation radiator heating for a banal reason - replacing radiators for them is already too "expensive pleasure" and additional spending on hiring specialists can turn into a collapse for the family budget. However, if you are actually afraid to take on such work as installing a heating radiator, then it is better not to risk it. After all, specialists will be able to do everything really efficiently. But the only difficulty lies in the fact that you really need to find professionals who know the options for installing heating radiators and their subtleties, and not self-taught people who will install radiators for the second time in their life. Hiring such a “master” can have dire consequences.
