What is the purpose of a hydrostrelka

Insulation is essential for keeping our homes warm and comfortable during the cold months. However, are you familiar with hydrostrelkas? Although this word may not be familiar to you, it’s crucial when it comes to home insulation and heating. What then is the precise function of a hydrostrelka?

A hydrostrelka is essentially a specialty tool used during the home insulation process. Its main purpose is to make sure that the insulation is dispersed evenly throughout the walls and that there are no spaces or gaps that could reduce how effective the material is. Consider it the finely tuned device that guarantees your house remains comfortable and heated, even in inclement weather outside.

However, why is adequate insulation crucial in the first place? Insufficient insulation would cause your house to lose heat quickly, which would increase your energy costs and make it less comfortable to live in. In order to keep your home comfortable throughout the winter, your heating system may need to run longer during the colder months due to leaking walls.

The hydrostrelka is useful in this situation. Contractors can ensure that all of the nooks and crannies in your walls are filled with insulation by using this tool during the insulation process. This helps to maintain a more constant temperature throughout your house in addition to increasing its overall energy efficiency.

Therefore, knowing how a hydrostrelka works in the insulation process is essential, whether your goal is to save energy costs or just to make your home cozier in the winter. You can always have a cozier, more welcoming environment in your house by making sure it is adequately insulated.

Why do you need a hydrostrel in a heating system?

The hydrostrelka completely neutralizes the dynamic influence between the two independent circuits for heat transfer in a heating system. It serves two objectives:

• first – it eliminates the hydrodynamic influence, when switching off and on some circuits in the heating system, on the entire hydrodynamic balance. For example, when using radiator heating, underfloor heating and boiler heating, it makes sense to separate each flow into a separate circuit, to eliminate the influence of each on the other.(see )
• second – with a small flow rate of the coolant – it should get a large flow rate for the second, artificially created circuit. For example, when using a boiler with a flow rate of 40 l / min, the heating system turns out to be 2-3 times more in terms of flow rate (consumes 120 l / min). In this case, it is advisable to set the first circuit by the boiler circuit and the heating isolation system by the second circuit. In general, it is economically inexpedient to accelerate the boiler more than it is provided by the boiler manufacturer, in this case the hydraulic resistance increases, it either does not give the necessary flow rate, or increases the load of the fluid movement, this leads to increased energy consumption of the pump.

On what principle the hydrostrelka works?

The circulation of the heat transfer medium in the primary circuit is created by the first pump. The second pump creates circulation through the hydronic jet in the second circuit. In this way, the heat transfer medium is mixed in the hydrostrip. If the flow rate in both circuits is the same, the heat transfer medium flows freely from circuit to circuit, creating a single, common circuit. In this case, no vertical movement is created in the hydrostrip or this movement is close to zero. If the flow rate in the second circuit is higher than in the first circuit, the coolant moves from bottom to top in the hydrostrelka, and if the flow rate in the first circuit is higher, it moves from top to bottom.

A minimum vertical movement is required for hydrostatic jet calculation and adjustment. According to the economic computation, this movement shouldn’t be faster than 0.1 m/s.

Why to reduce the vertical velocity in the hydrostrip?

In addition, the hydrostrelka acts as a settling tank for system debris, which is extracted from the heating system when it settles there over time at low vertical velocities.

Formation of natural convection in the hydrostrelka, causing the hot coolant to shoot upward and the cold coolant to descend. In doing so, the required temperature pressure is produced. To ensure quick water heating, underfloor heating can be used to lower the secondary circuit temperature and raise the boiler temperature.

Lowering the hydrostrip’s hydraulic resistance,

Tiny air bubbles in the coolant are released, and the coolant is then removed from the heating system using the autovozdushnik.

How to know if you need a hydronic booster?

The hydrostrelka is typically installed in homes with more than 200 square meters of space.In homes having intricate heating systems. where multiple circuits are used to distribute the heat carrier. Such circuits should be isolated from other circuits in the overall heating system. With the help of the hydrostrelka, you can establish an incredibly stable heating system and evenly distribute heat throughout your home. With the use of this system, variations from the predetermined parameters are eliminated and the heat distribution throughout the circuits becomes precise.

Advantages of using hydraulic arrows.

The prevention of thermal shock in cast iron heat exchangers. In a traditional system, disconnecting some branches and then adding already-cold, cool coolant causes a sudden spike in temperature without the use of a hydraulic shooter. By maintaining a steady boiler flow rate, the hydraulic arrow lessens the temperature differential between the supply and return.

Boiler equipment becomes more dependable and long-lasting when it operates steadily and without temperature swings.

Lack of imbalance and development of the heating system’s hydraulic stability. It is very difficult to increase the additional coolant flow rate by installing additional pumps, but hydrostrelka makes it possible.

More commonly, the hydraulic divider is referred to as a hydraulic shooter. Its application shouldn’t raise any questions because it is so straightforward. Just glancing at the device will suffice to explain why you would need one.

The hydrostrelka is not a long, relatively large pipe; instead, it resembles an elongated barrel with branches that are smaller in diameter.

The hydraulic splitter is obviously required to maintain pressure equilibrium in all pipelines that are connected to it. In fact, the moment the supply and return pipelines are connected to this thick pipe, the pressure within them will instantly equalize because the device’s hydraulic resistance is negligible—experts refer to it as "zero."

But what use is that in real life? Under what circumstances will it be necessary to balance the pressure in the supply and return pipes?

In order to determine whether or not the hydrostrelka is required, let’s examine its usage in more detail as well as the factors that need to be taken into account in the heating system. Prior to that, though, there is something else we must comprehend: why are there so many interpretations and installation suggestions for such a basic device? Additionally, the legs extend from the $ to the u.е. т.е.

Where do the difficulties come from

Despite its straightforward appearance, the hydro-jet itself is not inexpensive. Instead of in the garage, the firm version costs $250. Its use also includes the less than $100 worth of piping (fittings, drains, and taps). Additionally, the total cost of installation for all of this is $400. In the branded version, the pipe is truly not inexpensive.

But this is not enough. If a simple system, under the sauce of "installation of the most useful hydro shooter", is transformed into a complex one, and stuffed with automatics (approximately as on the scheme below), t.е. take out from under the boiler pump 3 circuits (boiler, radiators, heated floors) and provide each its own pump group and connect it all to a branded manifold with this device, and install automation controller, then all this together can stretch to as much as 2500$. Here we get to the gold mine of "radiator installers".
And for what it is necessary to throw away such a sum? It turns out that you are welcome, because in the vast majority of cases hydrostrelka in the heating system is not needed, and does not play any special role. It is necessary only in really complex heating systems, with many circuits departing from the main line, provided with their own pumps.

In order to ensure that the adjacent circuits are not significantly impacted, it is imperative to maintain equal pressure on the supply and return lines. This is the time to use the hydraulic splitter along with all the accessories required to make it work.

In order to gain further insight into the necessity of a hydraulic splitter and its function, please refer to the diagrams below.

Peculiarities of application of the hydrostrelka

Consider a heating scheme with several pumps and with two boilers.

There might be a circuit for heating other distant locations, such as floors, a greenhouse, a garage, a sauna, or another house, from the supply (in red) branch. Other circuits include the warm floor, water boiler, and radiator circuits.

As you can see, different pumps are required for these circuits’ pumps. These circuits differ in terms of resistance and length. Whether we like it or not, turning on a strong pump in one circuit will alter the pressure at the parallel circuit’s boundaries. It has the power to completely overturn the jet, halt movement in the adjacent circuit, and lower the quantity of coolant flowing through it. The diagram that follows illustrates a way out of this predicament.

Currently, a hydraulic shooter connects the supply and return to the boiler. This indicates that the pressure within them is balanced and that the impact of the pumps within the circuits on the circuits adjacent to them is minimized. The system is now stable.

It is evident that the liquid will begin to flow through the hydrostrelka from the supply to the return. It travels from the supply to the return, meaning that the boiler self-short circuits to some extent. Is that not harmful? Is it not possible for the coolant to reverse the direction of movement?

How does a heating system with a hydraulic divider work?

When the fluid does not flow between the supply and return through the hydrostrelka, it is theoretically impossible for the heating system to operate in this manner. Because the supply and return circuits do not experience exactly the same pressure, this falls under the fiction category.

In theory, if the boiler circuit pump is malfunctioning or the boiler is too weak, the mode where the liquid switches from supply to return could occur.

The fluid can then circulate from supply to return through the hydrostrelka while being pumped by additional circuits. This is an emergency mode that needs to be turned off; it will be evident on the hot boiler and cold consumers. With this mode, the coolant in the circuits will be cool and the boiler will operate at maximum temperature.

In this instance, the boiler’s supply and return temperatures will differ significantly—in any case, greater than the manufacturers’ advised maximum of 20 degrees. This mode is bad for the boiler because it can cause the heat exchanger to malfunction or cause condensate to build up on the combustion chamber.

The mode—a tiny excess of the boiler circuit’s flow rate over the total of the consumers’ flow rates—occurs when the liquid partially circulates through the hydrostrelka from supply to return.

This results in a decrease in the temperature differential between the boiler’s supply and return, which is normal for its operation and even helpful when starting a cold system. All that matters is that the downward flow through the hydraulic divider not be excessive, which could occur from a completely illiterate system installation or from circuit failures. An autonomous boiler will also shut down far too frequently, which is bad.

"Special features"

The hydrostrelka is attributed "miraculous" properties in the form of:
– "increase of boiler efficiency";
– "optimizing pump performance with increased pump life";
– "cleaning of the system from debris";
– "increase of motor life of the whole system";
– "normalization of hydraulic equipment operation."
– "temperature optimization of collectors, with integral connection of the intake with improvement of all connecting components of the system and integrated circuits, for optimal heating of organics by infrared irradiation";
– "removal of spoilage from tenants", – etc.
All of these are either an advertising fiction that has nothing to do with reality, or a replication in free interpretation of a previously invented nonsense. Following some statements can be detrimental to the system. A hydraulic separator is only needed to equalize the pressure between supply and return in complex systems.

Whether it is necessary to install

It is most likely not necessary to install a hydrostrelka. Ultimately, isn’t the system not intricate enough that one circuit doesn’t "clog" another?

If there is a usual set – boiler, radiators, boiler – there is no need for a splitter. If even the radiator circuit is provided with its own separate pump, when the boiler pump is periodically turned on, the radiator pump is switched off by automation (boiler priority) and the conflict of these pumps does not occur. And the conflict of only two pumps (pressure and flow difference), – floors and radiators – can be easily eliminated without a hydrostatic shooter.
As a rule, it is necessary to equalize the pressure if more than one boiler is connected in parallel (backup is not taken into account), or there are 4 or more pumps in the system. Т.е. There are many circuits – 1st floor, 2nd floor, 3rd floor, pergola, winter garden, workshop, sauna … then with such a complex system will have to splurge and on the hydrostrelka and related equipment.

In other situations, a hydraulic separator is not required. Additionally, a small bypass with a tap between the supply and return can be used to manually adjust the heating of the return in order to optimize the boiler (the difference being no more than 20 degrees), which will be "pennies" in comparison to the accumulation of superfluous hydrostrelka.

Hydrostrelka: principle of operation, purpose and calculations

What then is hydrostrelka in a private home’s heating system? A hydrostrelka is a temperature and hydraulic buffer that maintains an orderly maximum flow of coolant and facilitates the processes of correlation between supply and return temperatures. Why would someone use a hydraulic arrow?

Why a hydrostrelka is required in the heating system is very easy to explain. Private home owners are fully aware of the imbalance in the heat supply. Boilers made today have a more compact volume contour. The consumer’s flow rate during circulation is also lower at this time. To improve system dependability and quality of work, a hydraulic shooter can be used to isolate its operations from the secondary circuit’s heat generator.

System hydrosplitter for heating

To understand why you need a hydraulic arrow in the heating system, you need to name a number of advantages of heating systems with a hydraulic thermoseparator. First of all, the splitter is a prerequisite of equipment manufacturers to guarantee maintenance on a boiler with a capacity of up to 50 kilowatts and more. With the help of an auxiliary unit, the maximum flow with laminar flow of the coolant is ensured. The temperature and hydraulic balance in the heating system is constantly maintained. The hydrostrel and the heating circuit are connected in parallel. This creates minimal pressure, performance and heat losses. The supply and return pipes are arranged according to the knee principle. This ensures the temperature gradient of the secondary circuits. If you select the best possible hydraulic shooter for heating, you can protect the boiler from the temperature difference between the supply and return pipes.

Prevents thermal shock to the equipment. The boiler operates more efficiently thanks to the hydraulic arrow. Furthermore, a portion of the boiler circuit’s coolant is supplied with secondary circulation. saves electricity and fuel. The volume of boiler water doesn’t change. A splitter can be used to make up for any flow deficit in the secondary circuit, if needed. With a hollow separator, the impact of the large capacity pumps can be minimized. Both the boiler and the secondary circuit receive the load.

The hydronic shooter’s operating principle stabilizes the system’s hydrodynamic processes. Mechanical contaminants in the coolant must be removed as soon as possible to prolong the life of the pump. Furthermore, the lifespan of sensors, meters, and valves is extended. Hydrostrelka maximizes fuel combustion heat utilization at the division of flows (independent consumer circuit and heat generator circuit).
