Scheme of a boiler room with a hydrostrelka

Maintaining a cozy and energy-efficient home requires setting up an effective boiler room, especially in places where wintertime lows can occur. In addition to keeping your house warm, a well-designed boiler room lowers energy expenses. A vital element of sophisticated boiler configurations is the hydro separator, also referred to as a "hydro arrow." This gadget is essential to improving the longevity and efficiency of the heating system.

The primary job of the hydro separator is to control the water flow between the home’s heating circuits and the boiler. This is especially helpful for systems that have several circuits that need to run at different temperatures, such as radiators and underfloor heating. It functions by returning colder water to the boiler for reheating while simultaneously directing hot water from the boiler to where it is most needed. This prolongs the life of the boiler by preventing overwork and optimizing the heating process.

Although installing a hydro arrow in your boiler room may seem intimidating, it is worthwhile once you realize its advantages. Your heating system’s efficiency is increased by the hydro arrow, which guarantees a balanced flow and temperature distribution. As a result, your home will heat more evenly throughout, respond to temperature changes more quickly, and be more comfortable overall. Furthermore, because it lessens the workload your boiler must perform, it can result in significant energy bill savings, making it a wise decision for any homeowner wishing to upgrade their heating system.

Hydrostrelka with a manifold: manufacturing scheme, drawing, features of use and reviews

February 27, 2016.

Many modern inquirers want to know how to attach a collector to a hydrostrelka (manufacturing scheme below). In addition, a growing number of experts are beginning to realize that connecting boilers with specialized hydraulic dividers is a reasonably efficient way to greatly increase the installed heating system’s efficiency.

Problems of old technologies

Many people know that boilers without connected pumps are often directly connected to the collector, and it is instead of such a variant, such a hydrostrelka with a collector is most often used (scheme of manufacture below). From boilers with pumps, these devices were simply removed, and therefore installed on each separate heating circuit, but in fact, this option can not be used in all situations, because, if at this point on the boiler still has a warranty, then in this case it will not be possible to remove the pumps, and if we are talking about a cast iron boiler, in the case of such a dismantling of its components in the first switch on the heating can burst even separate sections of the boiler, not withstanding such a temperature difference.

What gives this technology

Today, a specialized hydrostrelka with a collector is used to get rid of all of this (the manufacturing scheme is presented in the article). More specifically, this device isolates the boiler from the rest of the heating system by separating the hydraulics. For instance, a hydrostrelka with a manifold (the manufacturing scheme is shown) can support a single boiler pump, but multiple additional units of varying powers are installed in the system.

How it works

Such equipment has a very basic mechanism. We will not be disassembling any fancy gadgets just yet; instead, we will focus on the primary ways in which this technology can be applied.

Generally speaking, all that is needed is a regular piece of pipe, which serves as the basis for the hydrostrelka (hydrodivider). You can determine the ideal materials to use for the construction of such a device and what fundamental features it should have by calculating the hydrostrelka.

What is its purpose

Initially, designers attempt to work from the knowledge that the arrow is specifically meant for the separation of hydraulics. Nowadays, most manufacturers attempt to create boilers with built-in pumps, and these are pretty strong units.

Boilers featuring a closed combustion chamber, for instance, can have integrated pumps installed within. These devices have a maximum power of 300 watts, but if the object needs to be powered by 1000 m 2 for any reason, that power will not be sufficient to fully squeeze the heating system. and this is the typical heating region that such equipment is roughly intended for.

In this sense, using combined systems and installing extra pumps are required. In this case, hydrostrelka (purpose, calculation, manufacture – about this further in the article) can be used, as it will simply interfere with the boiler’s original pump rather than aid it. However, it’s important to keep in mind that most high-power equipment of this kind comes with a factory hydrostrelka already assembled, or at the very least comes with fairly detailed instructions on how to connect it.

The story is essentially the same if you use smaller boilers, but you will have to make it yourself in this instance.

Where it is installed

For floor boilers without an integrated pump, Hydrostrelka is installed to effectively protect the boiler from significant temperature fluctuations when the heating system is first turned on. For instance, standard steel boilers can be shielded from the generated condensate by this equipment, and cast iron devices can be shielded from the potential for individual section failure.

Such unpleasant circumstances are avoided by using a specialized hydrostrelka. In this instance, the boiler room plan and drawing are crucial because it’s important to select the appropriate equipment based on the characteristics of the heated object. The only thing to keep in mind is that different floor standing boilers require the use of an additional pump.

Initially, a person in his home wants to get an almost perfect heating system, spending on it at the same time reasonable money, and in this case, everything starts exactly with the boiler. For a small private house, you can choose a standard two-circuit boiler with a closed chamber, which will be mounted on the wall. At the same time, it should be properly understood that in the majority of cases to ensure the normal distribution of the coolant in this system may require the individual manufacture of the heating manifold hydrostrelka. In such a situation, a quite standard question arises: whether their pumps will be used and what should be done with the device in the boiler?

It is understandable that many people in these circumstances would rather just take the boiler pump apart to avoid damaging the system’s installed hydraulics, but some devices are designed in such a way that this process is unlikely to work. Under these circumstances, connecting a hydrostrelka boiler to a collector proves to be the best course of action.

How in this situation the installation is carried out

First, the distribution manifold’s scheme is sketched. Take into account the following scenario, for instance:

• Two floor heating circuits.
• The system will use an indirect boiler circuit, two spare circuits for a heat pump or a separate electric boiler, as well as the circuit of the hydrostrelka, that is, 5 circuits.

The process of drawing a manifold diagram is not difficult in this instance; all that is required is a basic knowledge of how such a system operates.

Manufacturing and calculation

It is important to remember that you can independently modify the amount of power your hydraulic boom will possess. In order to determine the capacity, you must start with the unique features of your space and the equipment that you use.

It will be possible to make an arrow that is longer even though the diameter of the threads will be smaller if you are not using the power of the device you have purchased. In certain circumstances, it is best to reduce the total power of the purchased equipment by up to two times. For instance, not every home requires devices with a power of 80 kW, so in these situations, leaving the equipment at 40 kW is perfectly acceptable.

How to position it

Hydrostrelka is a device that some people who make it themselves like to install right next to the boiler, but many experts advise installing it on the collector as well. This way, you can end up with a well-thought-out, harmonious design that will be simple to use, inspect, and maintain down the road.

The boiler in this case can be mounted approximately three meters before the installation of the arrow, while the supply and return lines of the boiler can be mounted through the floor, if the house has a floor heating pie. Otherwise, there are no fundamental differences in where your arrow will be mounted, and the main thing in this case is the installation of equipment with a suitable capacity and necessarily in a vertical state. If you make a hydrostrelka for a heating system (scheme/calculation above), in which a boiler without a safety valve is installed, in this case it is recommended to weld an inch thread to the upper part of the device for mounting a special safety group.

It is also advised to weld a small thread in the lower section to guarantee proper drainage and arrow filling. Cutting specialized couplings into the system "boiler, hydrostrelka, and collector" in order to install thermometers is a necessary practical requirement. It can simplify your life in the process of continued operation by making it simple for you to keep an eye on the heating system’s condition.

In the design of a boiler room for a residential house, the inclusion of a hydro separator, often referred to as a "hydro arrow," is crucial for enhancing the system"s efficiency and longevity. Essentially, the hydro separator works by directing water flow within the heating system, ensuring that the water circulating through the boiler is separated from the water used in the heating circuits. This mechanism not only helps in maintaining an optimal temperature balance across different heating zones but also minimizes the stress on the boiler by reducing frequent cycling and wear. Integrating a hydro arrow in the boiler room scheme can result in more consistent indoor temperatures and a more energy-efficient heating system, ultimately leading to reduced energy costs and increased comfort in the home.

How to make it

In this instance, welding a complete hydrostrelka by yourself shouldn’t be too difficult if you have experience with standard welding equipment. On the other hand, you must accurately recognize that you will be considering a great deal of subtleties when carrying out this work.

These days, it is not difficult to locate a drawing of a hydrostrelka; however, it is important to recognize that each drawing is unique and does not follow a set template. Although each specialist has a different perspective on the hydrostrelka’s structure, there are some universally accepted guidelines.

The arrow is a metal container with spigots welded to it for supply and return connections as well as connections to the boiler. Branch pipes for consumers are also integrated into the system.

Spigots intended for an automated air vent at the top of the installed arrow are an optional feature. A faucet spigot is installed in the lower portion of the same to guarantee the removal of various dirt and sludge. One option is to add a spigot later on to supply water to the system, among other things.

First rule

The "rule of three diameters," which states that the diameter of the hydrostrelka you install must be three times larger than this spigot parameter, is the most crucial rule that must always be followed. In order for the hydraulic splitter to carry out all of its fundamental duties, which are as follows:

• Separate the sludge from the system;
• to discharge gases;
• to equalize the hydraulic difference;
• supply heated water to the boiler to ensure its greater durability.

Many people would rather save money by making their own hydrostrels out of polypropylene, but this is a completely incorrect choice that is primarily made by those who are unaware of the specific requirements for using such machinery.

Because of this, it makes sense to use only complete metal pipes, which enable you to fully utilize the potential of such technology and will manifest themselves throughout the system’s lifespan in a really effective manner.

Steel hydrostrels and manifolds have one advantage over polypropylene (PP) and that is their variety, as steel can be welded into any shape. I have given my clients a lifetime warranty on all connections, including the hydrostrelka, and I have not renovated or repaired anything in the past ten years. Only stainless steel should be used if it is made of steel. Additionally, the "black" steel powder painting is only attractive from the exterior. The disadvantages include rust, thin-walled spigots with threaded threads, and a two to three year operating lifespan. PP-glue between 90 and 110 mm, and then for a long while forgot. Those who wish to sell more of their products talk about the metal.

BAXI Forum

What is the boiler room piping scheme, may I ask?

A 280 square meter house composed of half brick and ceramic blocks.

Warm floors (bathrooms) on the second floor + underfloor heating on the first floor + radiators + batteries in the attic.

I purchased both a Premier Plus 200 boiler and a Baxi 1400in boiler.

My goal is to assemble the boiler room on my own.

I drew two schemes, one with and one without a hydro shooter.

I have two inquiries:

1) if any of the schematics are functional. 2) Which scheme will use a less-clocked boiler (I may be mistaken; the boiler seems a little too large)?

Many thanks to all of the professionals who are willing to lend their insights.

The original drawing was placed on Radikal with visible inscriptions (below)

However, since the boiler’s capacity has been overdone, I would recommend a scheme with a constant high temperature of heat generation, a mixing group on the radiator circuits, a boiler without priority, and a pump to increase the temperature of the return flow. If the CO hydraulics is calculated, both schemes are quite functional, but the first one is cheaper. In the second scheme, the boiler operation mode is simpler (just change the pumps).

As far as I can tell, you have the TP in "comfort" mode. So why are there two mixing groups?

Technical specialist Yaroslav Grabik BAXI, Ekaterinburg +7 912 647 1684

Will the TPs function as shown in the diagram? Thus, the boiler room houses the mixing unit. And already, the first and second floor TP receive water from it that has been cooled. TP drew two balancing valves in order to balance these mains.

2) I’m not quite sure what you mean by pumps:

BAXI-Ural wrote(a): Source of quotation in the boiler’s second, simpler mode of operation (just switch out the pumps occasionally).

3) Another point that is unclear is:

BAXI-Ural stated (a): The pump used to raise the return temperature is the source of the quotation.

Original artwork on Radikal

FastPerson penned(a): Quotation source Which of the following pumps do you mean? BAXI-Ural penned (a): Source of quotation for the boiler’s second, simpler mode of operation (which merely requires changing the pumps occasionally)

It refers to both the hydrostrelka’s pump and its predecessor.

FastPerson penned(a): Quotation source Another unclear point is this: The source of the quote pump for raising the return temperature was stated by BAXI-Ural (a).

If it’s unclear, move on and spare us the bother. The schemes you’ve presented are pretty feasible; I’m referring to additional optimization.

Technical specialist Yaroslav Grabik BAXI, Yekaterinburg +7 912 647 1684

Could you please confirm whether the last variant’s single-pump underfloor heating scheme is feasible?

The diagram you have given is a schematic hydraulic circuit diagram .
Now, the heating system is radiator – you have a radial with the installation of thermostatic valves. The question is whether you have made a real hydraulic calculation. Is the Kvs value calculated for valves and three-way valves?. The use of one pump for three different branches assumes the presence of automatic differential pressure regulators. which should be in front of each manifold .
You should have flow meters on the manifolds to adjust the design load per section (radiator) .
Installation of mixing unit on radiator heating assumes temperature schedule different from 80-60.
TP – the question will work or not, provided you calculate the resistance of the TP system and select a competent pump and adjust the hydraulics in accordance with the calculated data. it will work .
If thermostatic valves are to be installed, the pump must also be frequency controlled. Or installation of automatic relief valve with pre-setting .
For such a system, I consider the presence of automatic controllers to be mandatory !

It’s not a boiler room, either. heat-generating device The specifications for a boiler house are outlined in SP 89.13330.2012, if that’s still how you define it.

Oh dear. Oh my gosh, lecturer! Come on over and join us for a drink!

Plehan composed (a): The quotation’s original The pump should be frequency controlled if thermostatic valves are intended to be installed.

Responds to Viewers’ Most recent message

We have:

Baxi slim 62, boiler premier200.

the boiler is connected FOR the arrow (it so happened, to redo not an option, do not kick )

also there are many zone pumps.

The following has now been done:

1. the arrow pump is ALWAYS on

2. DHW boiler pump is connected from the boiler (as it should be) terminals 1,5 A8

3. all pumps are connected via contactors controlled by zone thermostats, which are generally energized from the boiler pump output. in this way the priority of DHW is realized. after a lot of struggling, like. Good day!

For background, here is my equipment selection thread .

Earlier I was planning to use a floor standing boiler, but now I am looking at LUNA-3 Comfort 1.310 Fi and BCN PREMIER Plus 300 + Three-way valve motor kit + DHW circuit water temperature sensor.

Can you please tell me if I need a hydrostrelka or I can do without it?.

Hint! If you can tell me the required nominal circulation volume and head losses in the CO for this circulation. geek:

And to make a long story short, – if the connection is made without narrowing, it should be enough. Good day dear forum members! Faulty board, after a thunderstorm the boiler stopped starting. When examining the board found

It is also necessary to change the optocouplers next to the ignition unit. It was written here. Advice required in connection with the conversion of a boiler to gas.

Before that there was a Wicker boiler connected through termovar with thermostat opening at 72 degrees.(analog of ladomat) with a 500 liters thermal accumulator is followed by a boiler distributor 80/60 for 3 circuits 221bb699c184e8c676516162d05f1888c9.jpg .

Thank you for your advice I have a Baxi Slim 1 in the boiler room.490 in, on the order of gas engineers made 1. boiler chimney: diameter as at the boiler outlet (I have 160 mm on the "mushroom"), stainless steel, inside the room insulated (sandwich), outside – stainless steel, around insulated independently 2. boiler room ventilation, 125 mm, is raised in the same brick channel as the chimney 3. inflow: a hole in the wall 100×100 "into the adjacent room" – into the garage, the area is 80 squares, there is a ventilation duct 160 to the garage. [quote="Igor-2 ":xjryz8bu] 33309 There are no miracles here Miracles do happen: today I noticed that the boiler room is suspiciously warm, the boiler is working and does not seem to blow cold from the ventilation.

I was not lazy, went to get a ladder, put a leaflet on it – it was almost pulled into the pipe. That means that the ventilation is now working as it should. I remembered – nothing has changed in the configuration of the inflow in the garage. The only thing that has changed:

– the temperature outside has risen to -3. -5 from -30 some more.

Hydraulic boom for heating – principle of operation, purpose and calculations

Without the use of specialized units, a traditional heating system may have some drawbacks. Without significant alterations and adjustments, its operation will become unbalanced. An appropriately positioned hydrostrelka for heating aids in balancing the system. It’s critical to use this node to lower the boiler’s internal temperature fluctuation level and facilitate the seamless operation of the circulation pumps. Under the current circumstances, most heating systems exhibit a need for hydraulic arrow. In terms of functionality, it serves as a compensation chamber that connects separate heating circuits.

Component	Function
Boiler	Heats up water to be circulated through the heating system.
Hydraulic Separator (Hydrostrelka)	Helps in maintaining proper circulation and separation of flow between the boiler and heating circuits, reducing interference.
Pumps	Circulate water through the system to ensure consistent heating.
Expansion Tank	Compensates for pressure changes due to temperature variations in the system.
Safety Valve	Releases excess pressure from the boiler to prevent damage.

Enhancing the efficiency and functionality of residential heating systems can be achieved by comprehending the layout of a boiler room using a hydro arrow. A hydro arrow, which is a hydraulic separator, is incorporated into the system to balance the flow between the boiler and the heating circuits. In addition to maximizing energy efficiency, this prolongs the boiler’s life by avoiding frequent on/off cycling, which is hard on the system.

Furthermore, the hydro arrow is essential for preserving a constant temperature throughout the house. It guarantees consistent and even heat distribution, improving comfort levels all around. This is especially crucial for larger homes or those with several heating zones, as these types of homes can have more noticeable temperature differences without this kind of system.

The long-term advantages of including a hydro arrow in your boiler room design may be of interest to homeowners thinking about renovations or new installations. These include better energy efficiency, which results in lower utility costs and a smaller environmental impact, and less wear and tear on the boiler. The initial cost of installing a well-designed boiler room with a hydro arrow is justified by these benefits.

In summary, adding a hydro arrow to your boiler room arrangement will maximize efficiency and boost dependability for your residential heating system. This configuration ensures that your heating system runs smoothly and effectively for many years to come by promoting a balance that lowers maintenance issues and operating costs. It makes sense to invest in these technologies for sustainable home management.
