Installation of heating radiators: norms and rules of
Installing a heating radiator is a crucial task, the quality of the implementation of which determines the operation of the entire system. To avoid a flood in the apartment and leaking connections, you should know the procedure and rules for the installation of heating appliances. We will tell you how to install a heating radiator.
Installation of heating radiators
Piping layouts
The rules for installing radiators may vary depending on the type of heating system and the method of connecting devices.
By type of system can be:
- Single pipe. Here, the products are connected in series to one pipe, which carries out both the supply and the return flow of heat carrier. In this case, the return flow of the previous convector is the flow of the next one, and each next node receives a slightly cooled coolant;
- Two-pipe. In this scheme, products are connected in parallel between two pipes: supply and return. In this case, the coolant of approximately the same temperature is supplied to all the nodes;
- Collector. Here there is a combination of the two previous methods: between two pipelines, supply and return, one-pipe circuits with one convector are connected in parallel. Since there are usually many such circuits, they are connected through collectors, which was the reason for the name of the wiring type.
Note! It is simple to distinguish one system from another: in a single-pipe system, only one pipe fits into each heat exchanger, in a two-pipe pipe there are two pipes, in a collector system, two pipes from each device go to a collector node.
The installation scheme of radiators has the main differences in the implementation of a two- or one-pipe system. The fact is that the installation of heating radiators in a one-pipe system according to SNiP requires a bypass, which prevents the circuit from breaking if one of the convectors breaks.
In the case of collector and two-pipe circuits, the batteries are connected in parallel, and the circuit does not break. Removal and installation of the heater radiator is possible without shutting down the system. To do this, simply shut off the taps installed on the inlet and outlet nozzles of the coolant.
Note! Two-pipe and collector wiring systems are considered more efficient and progressive, but their price is higher due to the greater number of pipes of the heating system and valves.
Battery Connection Methods
In addition to wiring, how to install a heating radiator is affected by the way it is connected to the pipeline.
There are three such methods:
- Side connection. In the houses of Soviet construction is most common, especially with vertical wiring, when one or two risers enter the room, two branch pipes, to which one side of the battery is connected, enter from the room;
- Bottom connection. This method is more typical of horizontal wiring, when the line goes along the floor or under it, and the device is connected to the lower collector axis to the nozzles;
- Diagonal connection. Can be used in both versions of the layout. Here, the delivery nozzle enters the upper opening on one side of the product, and the return one comes out of the lower opening on the opposite side.
Note! There are still disputes over which wiring diagram is correct. It can be said that the bottom connection is the least efficient, while the diagonal method heats the heat exchanger most evenly.
Installation rules
Before you install radiators, you should learn the basic rules and regulations for their installation.
There are rules that are rather recommendatory in nature:
- The battery is installed under the window. The central axis of the window opening must coincide with the central axis of the product. This avoids drafts and condensation on the glass;
- It is desirable to arrange the inlet pipes with a slight bias towards the movement of water. This will prevent the entry and accumulation of air in the heating unit and the associated loss of heat transfer.
There are also more stringent rules:
- The window sill should not completely cover the battery, otherwise convection currents will not heat the window glass, which can cause window misting and condensation on the window sill;
- The distance from the top of the convector to the window sill should be at least 5 cm;
- The distance from the bottom of the product to the floor should not be less than 5 - 10 cm;
- There should be a gap of at least 4 cm between the back wall of the device and the wall;
- The window sill can cover the device no more than half.
Note! Compliance with these distances will allow normal convection and circulation of air flow, which is a prerequisite for good heat transfer.
Battery installation procedure
If you want to install a heating convector yourself, you should know the order of work:
- Shut off the supply taps, then dismantle the old device;
- Mark up the mounting points of the brackets for the new product;
- Fasten the brackets to the wall with dowels or anchor bolts;
- We hang the product on the brackets, check the geometry with the help of the level: it should stand strictly horizontally, without distortions;
- We assemble an armature set: install the valve and valve under the thermal head, as well as the Mayevsky valve for air sgon;
- Connect the pipes from the main pipe to the heat exchanger.
Note! Installation of cast iron radiators requires more serious preparation and selection of fixing fittings, since their weight many times exceeds modern aluminum or bimetallic analogues.
Conclusion
The replacement and installation of heating devices should be taken seriously, since the quality of these works will determine the comfort in the house. To install correctly, you must follow the installation instructions and accepted standards. The video at the end of the article will help you avoid mistakes in your work.
