Heating batteries, which are often installed by consumers on their own, must be selected correctly, taking into account the number of sections and material. Only in this way will it be possible to create a heating system that will be distinguished by efficiency.
Radiator wiring methods
There are several wiring methods, among them - side one-way connection, bottom, diagonal, as well as serial and parallel. The first option is the most common, it involves the connection of the supply pipe to the upper pipe. Whereas the outlet pipe is connected to the lower one. This approach provides high heat transfer. If the coolant is supplied from below, then the supply pipe must be connected to the lower branch pipe, while the power will be reduced by 7%. When using multi-section radiators that are connected according to a one-sided side principle, the last section will not be hot enough. In order to prevent this trouble, you need to additionally mount an extension of the water flow.
Features of the lower and diagonal connections
Heating radiators, which you can install yourself, can be connected with the bottom connection. Such wiring is used in cases where pipes must be hidden under the plinth or in the floor. This connection method is the most suitable from an aesthetic point of view. The return and supply pipes should be located at the bottom, and they are directed to the floor vertically.
If you want to install multi-section radiators, it is best to use a diagonal connection, as it will be the most rational in this regard. The principle of tying in this case is that the hot coolant supply pipe is connected to the upper pipe on one side of the radiator. On the reverse side, the return line is discharged through the lower pipe.
Features of serial and parallel connection
If you have purchased heating batteries, the installation of these elements of the system can be carried out by specialists, but you will have to pay extra for these works. Whether you decide to do the installation yourself or with outside help, you first need to choose a wiring diagram that can be sequential. At the same time, water moves under pressure, and it is best to use a Mayevsky crane to remove excess air. This connection has one drawback, which is the need to completely turn off the heating system when you need to replace orrepair radiator. In cold weather, such work will be rather inconvenient.
Through the heat pipe built into the heating system, water enters when connected in parallel. Withdrawals are made on the same principle. The outlet and inlet taps will make it possible to replace the batteries without shutting down the entire system, but such wiring also has one drawback, which is expressed in insufficient heating of the batteries at low pressure in the system.
Determining the location of the radiator
Heating batteries, which were installed in accordance with all the rules, will work as efficiently as possible. To do this, it is important to determine the distance from the upper grille to the window sill. The same applies to the distance between the lower edge of the battery and the floor surface. In order for the heated air to be able to circulate normally, which has a positive effect on the heat transfer of the heat source, it is necessary to provide a distance of 5 to 10 centimeters from the window sill to the radiator grille. About 8-12 centimeters should remain to the floor. The radiator should be removed from the wall by 2-5 centimeters. If the surface is to be supplemented with heat-reflective insulation, then the standard fasteners may not be long enough. At the same time, you can purchase locking hooks, which have a more impressive length.
Calculate the number of sections
Do-it-yourself installation of a heating battery should be carried out only afteryou will be able to determine the required number of sections to create an efficient heating system. When calculating, you need to be guided by the rules that provide for the use of one section for every two square meters of area. At the same time, the height of the ceilings should not be more than 2.7 meters. If during the calculations the figure turned out to be not round, then it needs to be changed upwards. It should be borne in mind that heating an insulated cottage and a corner apartment can be considered two big differences, so it is recommended to calculate the required number of sections individually, taking into account the technical characteristics of the batteries and specific conditions. Among the latter, one can single out heat losses on especially cold winter days.
Preparation of tools
The installation of radiators in a private house is carried out using a certain set of tools and materials, namely: pliers, tape measure, screwdriver, pencil, impact drill and a wrench for twisting pipes. To install the sections, a special key will be required, so the assembly and connection of the sections should be ordered from the store. When using bimetallic radiators, do not use a file or emery when cleaning the surfaces to be joined.
Work technology
Installation of radiators is carried out in a certain sequence, it provides for the dismantling of old radiators at the first stage. Next, you can make a markup for installing fasteners. The next step is to mount the brackets and installradiators. The master must assemble the installation kit, as well as fix the taps and valves under the thermal head. To bleed air, a Mayevsky crane should be installed. At the final stage, you need to connect the heating pipes.
Specialist recommendations
Installation of radiators can be done by you yourself. Before starting work, it is necessary to shut off the heating circuit, and then drain the water from the system. The pump will help to qualitatively cope with this task. Using the level, you should analyze how correctly the battery was installed on the supports horizontally and vertically. Plugs are unscrewed from the equipment, and then a bypass equipped with a valve is installed. It should become part of a single-pipe circuit. For connection, use a squeegee with a valve attached to it. Using a threaded sleeve, the radiator can be connected to the system, and it is recommended to use a tow-type sealant to seal the joints.
Conclusion
It is worth remembering that the installation of radiators in the apartment must be completed by removing the packaging shell. After pressure is carried out, for which you need to use the services of a plumber. After all, it makes no sense to purchase a device for carrying out these manipulations at a time. You can independently equip a system that is responsible for heating the house. Installing batteries will be one of the steps in the process. They can be used as products made of cast iron, which, although not so common lately, is still used by consumers. Before installation, you need to unscrew the battery and adjust the nipples, and then reassemble it.
