Distribution manifold. What are the distribution manifolds

Any heating system of an apartment or apartment housewill work properly, if you establish this process, and do it really even yourself. However, each one is inclined to decide this question in his own way. The most popular way to achieve productive work of the heating system is the use of distribution manifolds, their main function is to proportionally distribute the flows emitted by the coolants. This technology has many features and advantages. They will be discussed below. It is noteworthy that you can set up the system yourself, as well as make a collector.

Description

In general, the distribution manifold representsa metal comb, which has a number of leads, they are intended for connecting home heaters, as well as for adjusting the volume of the temperature and the water supply pressure. This device centrally controls heating processes in a separate room in the living space. This element of the system can be adapted to radiators, warm floor, convectors and panel heating methods.

The device has two interconnected parts,which are combined into one block. The first of these is the supply manifold, while the second is the return one. The first is aimed at controlling the flow of coolant to the existing circuits, which can be closed by valves if necessary.

Need to use

The return collector is required for proportional heating of premises, which is provided by balancing the pressure level in the branches.

The distributor manifold is mounted oneach floor, if it comes to a large private building. The system is very convenient, because with its help you can adjust the temperature not only on each floor, but in every room. And when repair work will be enough to disable only one circuit, with the rest of the house will not be deprived of heating.

What are the collectors

Special variations of the equipment described abovedoes not exist, whereas the differences depend on the material at the base, the number of circuits and the built-in auxiliary devices. Production of combs can be adjusted using materials that are resistant to external negative factors, while the functionality and complexity of the equipment can be completely different.

Considering the above, the following types of reservoirs can be distinguished:

• brass;
• polymeric;
• copper;
• steel.

The number of loops can vary from 2up to 12 pieces. With increasing heating equipment, you can easily add the missing circuits to the common system. The level of complexity of the design can be different, so we should also highlight simple as well as improved types of distribution combs. The first do not have auxiliary parts to correct the operation of the device, while the latter have built-in control elements, a large number of fittings, special sensors and automation. The simplest version of the collector is a tube with a number of branches and a pair of connecting holes on the sides.

Complex collectors

If it is a more complex model, it can be equipped with:

• sensors;
• control units;
• automatic thermostats;
• electronic mixers;
• valves;
• automatic air release devices;
• valves for draining the water.

Sensors are required to take into account the level of pressure andtemperature. With the help of control units a coolant is supplied, but automatic thermostats maintain a certain level of pressure in the system, whereas when the admissible values ​​are exceeded, they reduce it. The pre-programmed temperature is maintained by means of mixers and electronic valves.

Collector production

Distribution manifold (collector) can bewas done by you yourself. First, you need to plan everything, but first you need to determine the components of the heating network. It is important to know the number of circuits, the number of heating equipment, as well as the number of additional equipment. As for the first factor, you should know where the coolant will be sent. If we are talking about heating equipment, then we must determine its power, water temperature, etc. In addition, if it is planned to incorporate heating elements into the system in the future, it is best to consider everything in advance, this also applies to heat pumps, and also solar panels.

You must calculate the amount of equipment fortype of valves, storage tanks, fittings, pumps, manometers, thermometers and other. You can make a comb for water. The distributor collector should be started only after determining the design of the device. It is important to consider where each circuit will take place, and from which side you will fail it. Experts advise paying attention to the nuances of connection. For example, electric or gas boilers are connected from below or from above to the collector. If there is a circulation pump in the system, the connection is only from the end of the comb. As for solid-fuel aggregates and indirect heating boilers, their insertion is carried out exclusively from the end. But the feeding contours cut from below or from above.

Advice of a specialist

The distance between the branch pipes of the return loop andflow should be in the range of 10 to 20 cm. It is not necessary to increase or decrease this value, since maintenance will be accompanied by difficulties. In the same range, it is necessary to arrange two compartments: a return and a feed.

Manufacturing procedure

If you will install a distributivecollector, the return and supply compartments must be made of a square and round tube. Some experts prefer the first option, since it is easier to work with. It is important to follow the sequence of work, it involves the preparation of appropriate materials, which should be connected to the drawing with a welding machine. The joints should be cleaned with an iron brush, if necessary - degrease.

The finished device should be tested fortightness, for which all the pipes are well closed, leaving only one. It should be filled with hot water. The distributor manifold was made correctly, if none of the joints flowed. At the next stage, the collector is colored and left to dry. The connection of all pipe systems is carried out at the next stage, as well as the installation of a stop valve. Some wonder whether it is easier to purchase a ready-made device. As practice shows, not always suitable for a particular heating system. Sometimes it is necessary to equalize the heat engineering indicators. For example, some resort to the decision to install an additional comb. This becomes a source of costs and creates an extra amount of work.

Place of installation of the system

Distribution manifold for underfloor heatingcan be installed on each floor, in this case a special collector unit is mounted. Usually it is a niche in the wall that is some distance from the floor. The niche should be located in a room, the operating conditions of which are not accompanied by excessive moisture. The device can be located on the wall, if it is a utility room. For this, collector cabinets for heating are also used. Usually they are made of metal and supplied with a door, and also with a stamping, which is necessary for piping in the side walls. Inside there may be mountings for the collector unit. Sometimes the cabinet is built-in or invoiced.

Price of collectors

The distributive manifold (2 circuits) canhave a different value, but if it is a manufacturer of Rehau, then it will have to pay 5500 rubles. Such devices are intended for radiator heating systems. If the basis is stainless steel, then the equipment will cost more, for this model on 2 circuits you will give 7300 rubles. The distribution manifold (3 circuits) will cost 5200 rubles, in this case it is the same company.

And if you are interested in the HLV 3 model, then youshould know about some of its characteristics. These devices are supplied with ball valves and are intended for radiator wiring. Coating does not have a casing, as a material of manufacture, brass is used. This manifold is tested in the process of manufacturing under high pressure and consists of two distribution pipes, the diameter of which is 1 inch. Connection is possible on both sides.

If you are interested in the distributioncollector HKV, then you should know that this device is an equipment with control valves. It is intended for a warm floor and has two exits. The basis is stainless steel, there are no flow meters in the kit. The brackets are galvanized and soundproofed, and the supply line is equipped with regulating valves. Such a collector of water distribution valves is equipped with cranes, so they do not have to be purchased additionally.

Which collector to choose

As practice shows, the widestThe range of collectors is represented by Oventrop. The equipment of this company can be designed for any kind of heat generator, the device can have a pump. The outlets and the Oventrop collector manifold are not made of plastic, but of stainless steel, this eliminates the deformation of the elements when exposed to high temperatures. Ball valves, sealing valves and nuts are made of corrosion-resistant brass, this significantly extends the life of the collectors.

Conclusion

If you do not want to spend money on heating unoccupiedpremises of the house, then you need to purchase a distribution manifold. Rehau and many other companies today offer such devices. Make the right choice, you can by reading the characteristics and prices, but if you do not want to spend, then this device can be performed independently.
