The sale of components on the site implies a factory warranty. Valid for the buyer affordable prices on collectors for radiator heating, because We have established our own channels of cooperation with manufacturers.

Design and types of collectors

Radiator heating distribution combs consist of two main parts - supply and return manifolds a. The first serves to regulate the supply of coolant, and the second serves to proportionally heat the premises by balancing the pressure in each branch. The distribution into types is conditional and implies the assembly of the unit:

automatic air release valves for water drainage;
electronic mixers and valves to maintain a given temperature;
automatic thermostats - maintaining the pressure in the system within the normal range;
coolant supply control units;
pressure and temperature level sensors.

The price of the unit will depend on the configuration and number of circuits. The device is equipped with shut-off valves to shut off the flow along each branch.

Collectors are designed for distributing liquid from the main line through additional circuits, for mixing and uniformly distributing flows from parallel pipeline branches, as well as for return collection during circulation. Collectors for radiator heating improve the properties and characteristics of heating systems in buildings for various purposes.

Collector design

The design of a collector for a heating system is quite simple: it is a piece of pipe with a certain number of end and side outlets for connecting individual circuits. There are devices equipped with a security group, mixing unit, air vent, automatic or manual flow regulators. Such equipment is used only in circulation closed systems heating and provides automated control them.

Types of collectors for heating systems

Depending on the design features and purpose, collectors are divided into 4 types:

Distribution manifold

The most common type that separates coolant flows among heating devices. It consists of 2 distributors (combs), at the ends of which devices are installed for connecting to the supply and return lines. Along the body there are fittings for heating devices(underfloor heating circuits or loops, heating radiators). Through the first distributor, the coolant flows to the heating devices, and through the second, it is discharged back to the boiler. The connection of radiator-type heating through the distribution manifold is carried out in parallel, and not in series, as in one- and two-pipe schemes.

Hydraulic manifold or thermohydraulic distributor

Designed for hydrodynamic balancing of the heating system complex type(With several heating circuits). Equalizes the temperature and pressure of the coolant in different circuits, while the flows can be mixed to the required extent. This ensures a stable temperature in the premises, as well as gentle operation of the equipment.

With pump

The thermo-hydraulic distributor allows you to achieve optimal performance heating systems in a large building when each circuit is equipped with a pump. This type of collector is different large diameter and is installed vertically in the boiler room.

Solar

Directs solar energy for economic needs. As a main source of heating, it is suitable for heating water in water pipes located in areas with sufficient levels of sunlight. Fittings of this type differ in design from a conventional collector and often serve as a heat exchanger.

Installing a collector for radiator heating will allow you to use the system as efficiently as possible, which will ensure rational heating of the premises.

Manifolds for radiator and underfloor heating

Today the most common way to achieve effective functioning heating systems is the use of distribution manifolds, the main task of which is the proportional distribution of the coolant and regulation of its parameters: volume, temperature and supply pressure. The efficiency of the heat supply system depends on the amount of coolant passing through the pipes, the volume and speed of its movement.

According to Federal law No. 261 on “Energy saving and heat metering”, it is necessary to implement heat consumption metering for each apartment, which is most easily implemented by systems with collector distribution of coolant.
Advantages when installing collector systems:

It is possible to use hidden pipelines.
convenient for installation, since there are no pipe connections in the floor.
ease of adjustment of individual loops of the heating system.
the ability to turn off the radiator along with the supply pipes without turning off the entire heating system, that is, the ability to replace a separate section during the operating mode of the system.
ease of installation of water heated floors. The warm floor is connected as a separate independent circuit. This is due to the fact that the temperature of the coolant in the underfloor heating system is lower than in the heating system, which is ensured by installing a special mixing circuit.

Distribution manifold heating system is equipped with many terminals intended for connecting heating devices and consists of two interconnected parts: supply and return manifolds, combined into a single block. The first directly controls the feed hot water to the circuits, and the reverse proportionally distributes the coolant to heat each room in private houses. If the house has two or more floors, then collectors are installed separately on each. Such a system is very convenient, because it allows you to regulate the temperature on each floor and in each room, and in case of emergency it is enough to simply turn off the necessary circuit without turning off the heating in the rest of the house.

In the case of using radiator heating in conjunction with warm floors the absence of a distribution manifold can lead to the fact that the coolant will flow unevenly into different circuits of the system, and, for example, there will be a hot floor and cold radiators, or vice versa. Thanks to this distribution, the radiators heat up evenly, since each has a separate supply pipe.

Types of heating collectors

Unregulated collectors
When precise adjustment of flow in a heating or water supply system is not required, it is enough to simply mount a distribution manifold without valves and connect pipes of the required diameter to the outlets. For this purpose, unregulated manifolds with a diameter of 3/4" and 1" with a distance between taps of 36 mm can be used. Such collectors can be of pass-through or end-type.

End manifold
An end-type manifold is a manifold with an inlet on one side only, and the other side has no passage, eliminating the need to install a plug and the possibility of additional risk of leakage at that location.
If it is necessary to shut off the flow, it is better to use manifolds with a distance between taps of 50 or 100 mm, which will provide the possibility of installing ball valves sized 1/2” or 3/4”. The diameter of the collectors with a distance between taps of 50 can be 3/4”, 1” or 1 1/4”.

Depending on the size of the outlet
- one manifold outlet with a diameter of 3/4”, 1” or 1 ¼” with center distance 36 or 50 mm has a throughput of 5 to 9 m3/hour and can provide a flow rate of ~ 1 m3/hour at a flow speed of 1 m/sec. Such collectors are mainly used for floor or apartment distribution;
- one collector outlet with a diameter of 1”, 1 ¼”, 1 ½” or 2” with a center distance of 100 mm has a throughput capacity of 7 to 17 m3/hour and can provide a flow rate of 1 to 2 m3/hour at a flow speed of 1 m /sec.
Collectors with an increased distance between taps (100 mm) are recommended to be installed in main distribution areas: in cottage boiler rooms or in house water supply input areas. These manifolds have diameters ranging from 1”, 1 ¼”, 1 ½” or 2” and outlet sizes of ½”, ¾” and 1”.

1” diameter manifolds can be threaded or flanged. The flange connection of the collectors ensures 100% location of the collector outlets in the same plane.

Manifolds with built-in control and shut-off and balancing valves.
Regulating manifolds allow not only to completely open/close the flow, but also to accurately regulate the flow rate for each consumer. They are installed in hydraulic systems with pressures up to 10 atm and temperatures up to 100°C. Manifolds with built-in control valves can be installed on the flow and return lines. Flow control is carried out without using special tools. The sealing ring (made of EPDM) on the valve seat ensures reliable operation of the valve over a long period of operation.
End control manifolds with an inlet on one side only (the other side has no passage) eliminate the need for a plug and the potential for additional risk of leakage where the plug connects to the manifold.
The valve control handle and lockable shut-off cap are located on the front surface, providing the user with ease of service without the need for special tools.

Underfloor heating manifolds
Shut-off and balancing manifolds with built-in vertical valves can be installed in the water supply or heating system (on the supply and return lines).
Shut-off and balancing manifolds, equipped with a flow meter, allow you to measure and shut off the flow of liquid and balance the branches of underfloor heating and cooling supply. Based on the flow meter readings, the required flow rate can be set. The flow can be completely blocked by tightly twisting the handle.

Thermostatic manifolds.
Installed in the heating system on the return line if necessary manually or automatic adjustment room temperature.
Automatic adjustment is ensured by installing electrothermal heads instead of adjusting knobs. The electrothermal head, depending on the thermostat signal, provides the opening/closing value of the coolant passage and is intended for installation on thermostatic valves as a two-position (open/closed) control servo drive. Electrothermal heads operate on the ON-OFF principle (open/closed) from the electrical signal of an external thermostat with voltage alternating current 220V or 24V. Automatic maintenance of the required thermal conditions (room temperature, heated floor surface, etc.) can be carried out using thermostats. When voltage is applied, the thermal material heats up and the valve stem moves. When there is no voltage, the valve is in the closed position.

The comb can additionally be equipped shut-off valves, circulation pumps, thermometers and pressure gauges, deaerators, which together provide complete control over the movement of the coolant.

note what if you plan to use collector heating, then keep in mind that it will not be able to work without a circulation pump!

When purchasing a collector, you should pay attention not so much to the material from which it is made, but to its technical specifications: maximum permissible pressure, number of outlets, level bandwidth, the ability to add additional circuits if the number of radiators increases, the presence of automatic auxiliary devices.
Today, manufacturers offer many models of such devices, among which you can find devices that have a maximum set of elements: flow meters can be mounted on the supply part, which regulate the flow of the coolant in each loop, and temperature sensors can be installed on the return part to automatically control the temperature of each heating device. The price of such a collector will, naturally, be much higher.
