What is the hydraulic shotgun for

You most definitely do not require a hydraulic separator if installing a closed-loop, basic heating system in your home involves fewer than two circulation pumps.

In situations where there are three circuits and pumps, and one of them is intended to operate with an indirect heating boiler, a hydraulic shot is not necessary. When the scheme looks like this, it is necessary to consider the separation of heating contours:

Note: The cascade in this picture is powered by two boilers. However, this is not necessarily the case; the boiler is one.

Although the plan that is being presented does not include hydraulic shooting, its installation is obviously necessary. The same number of pumps with varying performances are valid in 4 circuits. The strongest one will increase pressure in the opposite direction and produce a vacuum in the supply collector. There is just not enough strength to overcome this vacuum and the pump won’t be able to take the coolant to his contour when it is operating at the same time as the less effective pump. Because of the pumps’ mutual interference, the branch will not operate.

Vital. The hydraulic resistance of the branches will always vary, even if the passport performance of the pumping units remains constant. Because of this, each circuit’s actual coolant flow rate varies, making it impossible to hang the system precisely.

The hydraulic rifle is incorporated into the circuit in order to remove the pressure differential ΔP that exists between the collectors and provide the appropriate amount of coolant to every pump. It is a calculated section hollow pipe whose job it is to establish a zero pressure zone between the heat generator and multiple consumers. The next section describes how this element functions in the boiler’s binding diagram.

Creating a hydrofoil for heating systems from polypropylene can be an efficient and cost-effective solution for improving heat distribution in your home. Polypropylene is a lightweight, durable, and flexible material that"s easy to work with, making it a popular choice for DIY projects. To make a hydrofoil, you"ll need to shape the polypropylene into a simple structure that directs heated air or water where it"s needed. This can be achieved by bending or cutting the material to create channels or fins, which guide heat flow more effectively. Be sure to use appropriate safety measures, like wearing protective gloves and eye protection, when cutting or bending polypropylene. With careful design and construction, a homemade hydrofoil can significantly enhance the efficiency of your heating system, helping to keep your home warm and reducing energy costs.

Binding diagram with a boiler

We suggest examining the hydraulic shootout’s strapping scheme with the boiler shown below in order to comprehend how it functions in the heating system’s multiple contours:

Both collectors are now linked together. As a result, each circuit will receive the necessary amount of coolant. The coolant flow rate from the heat generator must be maintained at the same time to prevent the consumer side’s temperature from dropping too low.

A hydraulic shotgun circuit, as seen above, is quite popular on the Internet and shows three different working regimes:

• the total flow rate of the coolant in the consumer contours and from the boiler is the same;
• Heating branches select more water than it is converted in the boiler circuit;
• The expense in the ring from the side of the heat generator is greater.

The hydraulic rifle, which is shown on the scheme under number 3, actually only has one mode of operation. Since thermostats constantly alter the hydraulic resistance of consumer branches, it is impossible to attain an ideal regime (No. 1), and it is impractical to pick up the pumps. Scheme No. 2 states that action is not possible since most of the coolant will turn away from consumers in a circle.

Because some hot water from the boiler will be mixed with the hydraulic rifle’s water, the temperature of the heating system will drop as a result. You will need to use a heat generator on maximum mode in order to raise this temperature, which isn’t good for the system’s overall stability. There is still Option No. 3, in which the collectors receive an adequate supply of water at the necessary temperature. And three-way valves’ job is to lower it in the contours.

The creation of a zero-pressure zone from which the coolant can remove any number of consumers is the sole purpose of the hydraulic shootout in the heating system. Making sure the heat source is being used as necessary is the most important thing. In order to achieve this, the boiler pump’s actual productivity needs to be marginally higher than the total amount of expenses incurred by each consumer branch. The video tells and illustrates more details about all the subtleties:

Scheme of the manufacture of a hydraulic shotgun with a collector

It won’t hurt to research this element’s device before purchasing a hydraulic shotgun or firing it manually. It’s very easy to understand: to connect the heating network, multiple pipes from different sides are installed inside the hollow pipe of the round or rectangular cross section. Additionally, the pipes that connect the feed and return are typically found in the upper and lower sections of the pipe, respectively.

The connection method that is specified is important when installing a hydraulic rifle vertically. It can also be installed horizontally at the same time.

The most common type of separator used for heating is a hydraulic one, which has a mechanism to install a collector. They even come in sets and are constructed of the following materials:

• low -carbon steel;
• stainless steel;
• From polypropylene.

More sophisticated models come with liners for attaching control devices and sensors, as well as different nets and plates, in addition to the air vent and drain fitting. They separate flows and clean the coolant. This type of hydraulic shotgun, whose mechanism is depicted in the drawing, is reasonably priced and needs to be maintained on a regular basis:

Home masters typically make a hydraulic shot out of a metal pipe, but this trend is changing as a result of polypropylene’s widespread use and low cost. After all, the collector and the element derived from the PPR are highly expensive. As a result, making a polypropylene separator at home is becoming more and more popular than purchasing one from a store. To accomplish this, you will need two plugs, tees in the number of future pipes, and PPR pipe with the appropriate diameter.

Given that the pipe used to make a hydraulic shotgun has a fairly large diameter, a welding machine nozzle that can withstand soldering for an adequate amount of time must be purchased. Nothing complicated in theory—plugs are inserted from the ends of the pipe segments that connect the tees. Furthermore, not every system that can be used will have a separator like this, and it might not have a very attractive appearance.

The truth is that robust heat generators can frequently operate in their highest mode, which allows the water temperature to approach 90–95 °C. Naturally, polypropylene can handle it, but in an unusual circumstance (like when the power is turned off), the temperature at the supply can suddenly rise to 130 °C. Solid-fuel boilers’ inertia causes this, so everything that is strapped to them—including a hydraulic shotgun—should be metallic. If not, you’ll face the appalling consequences shown in the picture:

Calculation of a hydraulic shotgun

Any heating system’s separator is chosen or manufactured based on two factors:

• the number of pipes for connecting all circuits;
• diameter or area of the cross section of the case.

Calculating the hydraulic boost is required to determine the diameter if determining the number of pipes is not too difficult. It is done by using the following formula to calculate the cross-sectional area:

G / 3600 ʋ = S, where:

• S is the area of the cross -section of the pipe, m2;
• G – heat carrier consumption, m3/h;
• ʋ – flow rate, accepted equal to 0.1 m/s.

As a point of reference. Because a zone of nearly zero pressure must be provided, the hydraulic separator’s water flow is moving at such a slow pace. The pressure will rise in response to an increase in speed.

Based on the necessary thermal power for the heating system, the coolant flow rate is calculated beforehand. The hydraulic rifle’s diameter on the cross-sectional area can be easily calculated if you choose to purchase or pick up a round section element. To calculate the pipe’s size, we use the school formula for the circle’s area:

It is essential to arrange the pipes at a specific distance from one another when assembling a homemade hydraulic shootout, regardless of how it got there. Using one of the following schemes, determine the distance between the inserts based on the diameter of the connected pipes:

Polypropylene can be a great option if you’re planning to use hydrofoil to improve the heating system in your home. It is strong, lightweight, and resistant to melting or warping in the heat. It’s also reasonably simple to work with, which makes it a useful choice for both professional installations and do-it-yourself tasks.

Make sure you have all the tools and supplies you’ll need before you begin. Clamps to hold the polypropylene in place, a heat source to shape it, and some simple cutting tools are required. Vapors can be released when heating plastics, so make sure your workspace has adequate ventilation. Wear safety glasses and gloves, or any other protective gear, because your first priority should always be safety.

Work slowly and give the polypropylene some time to shape. This will assist you in shaping your hydrofoil to the proper shape without sacrificing its structural integrity. To make sure everything aligns correctly, it’s also a good idea to test fit the components before permanently fastening them.

You can install your hydrofoil in your heating system once it is ready and shaped. Make sure you adhere to any installation instructions tailored to your specific system. For effective heat transfer to occur and to prevent problems later on, proper installation is essential.

Make sure everything is operating as it should after installing your heating system by testing it. Look for any indications of trouble, such as leaks or strange noises. You should be able to enjoy a more effective and efficient heating system if everything checks out.
