Every detail matters when it comes to maintaining a safe and effective home heating system. A crucial element that is frequently disregarded is the addition of a security group to your heating system. This crucial configuration aids in pressure management and shields the system from a number of typical problems that could result in expensive repairs or even system failure.
The security group is a compact but essential assembly in your heating system that usually includes an air vent, a pressure gauge, and a safety valve. Together, these parts allow the heating system to maintain safe operating pressure levels, release excess air, and guard against overpressure-related damage. Although it may sound technical, this simply serves to maintain the safe and efficient operation of your heating system.
Installing a security group will increase the longevity and efficiency of your heating system in addition to adhering to safety regulations. It assists in maintaining the ideal operation of your heating system, guaranteeing that your house remains warm without needless energy waste or damage risk. It does this by monitoring and controlling internal pressures. Any homeowner would be wise to think about adding a security group, whether they’re upgrading an existing system or installing a new one.

Device and assignment of a security group
This basic component essentially consists of three distinct devices that are mounted on the general collector. The latter has three seats in the shape of threaded holes and is constructed of brass or stainless steel.
A threaded coupling is installed beneath the collector to connect it to the heating system. He is being screwed by those above:
- manometer;
- automatic air vent;
- A resetting safety valve.
Consequently, the heating security group performs three roles; we will go into greater detail about each of them now. The pressure gauge provides visual control over the system’s overall water pressure as well as the pressure in the boiler tank. In the event that the heating system is shut off, he is also crucial in maintaining pressure and filling the network of pipelines.
The air sprayer’s primary purpose is servicing. Inside is a camera that has a float attached to a valve that opens when there isn’t any water. The device’s job is to extract air during operation and when coolant is being poured into the boiler and system. The initial parts of the steam that form in the boiler tank when it overheats are released, which is an extra function.
A safety valve is an emergency device that releases steam, water, or a combination of both in the event that the installed pressure threshold is exceeded. It turns out that the boiler security group’s basic mode of operation is to regulate and avert emergencies related to boiling the coolant in the heat generator’s water jacket. Ultimately, what is going on? The manometer records the increase in pressure first, followed by the pairs that emerge and travel through the air span. A safety valve is then used to release the water or steam-water mixture from the system.
Absence of the security group in the heating system would unavoidably lead to overheating and an explosion of the unit’s shell, with all the associated repercussions. The discharge valve will therefore empty the water until the pressure reaches the allowable framework if you do nothing. While some boiler plants have a maximum working pressure of 1.6-2 bar, the majority of boiler plants have an upper pressure threshold of 3 bar.
The scope of application
It turns out that the heating security group is not always necessary, but it can be added to any system as insurance at the homeowner’s request. For instance, heat generators that run on electricity and natural gas or diesel do not require additional safety measures. The boilers possess a high degree of safety and can abruptly cease heating in response to a rise in pressure or temperature.
Note: The security group is typically installed in closed heating systems with gas or electric boilers for ease of control and maintenance.
Hard fuel heat sources, however, have a high moment of inertia and cannot be stopped quickly. Fuel that enters the combustion zone takes some time to burn, even in automated pellet boilers. And picture a furnace brimming with firewood? When a temperature rises in the shirt, the thermostat or controller will immediately block the growth, but the process won’t stop right away. The firewood will continue to smolder instead of going out, raising the water’s temperature a few degrees. A security group is an essential component of solid fuel heat generators because it is the only thing that can stop boiling and explosions in these boilers.
Remark: The majority of manufacturers finish their solid fuel units with a security group at first.
Instructions for installation
A wood or coal boiler that does not have a security group installed can be purchased separately and put together without any issues. Selecting the appropriate gadgets for your heat generator is crucial in this situation. The automatic air ventricle’s technical features don’t really matter, but the manometer and emergency valve are chosen based on the boiler’s maximum working pressure as stated in the instructions.
Generally speaking, installing a security group in a heating system is not difficult and can be completed by anyone using a basic set of locksmith tools. There are two methods for carrying out installation:
- setting on a "native" fitting leaving the boiler;
- inserting into the supply pipeline at the output of the heat generator.
Vital. One important thing to keep in mind when installing the element is that you cannot install any reinforcement or connect any other devices using the tee on the location between the unit’s output pipe and the security group. Devices should ideally be positioned close to the boiler itself, keeping the length of this site as minimal as feasible. The complete list of these infractions is displayed beneath the image:
You should position the group on the feeding line in such a way that the boiler room entrance permits a clear view of the pressure gauge’s testimony. Installing a security group on a vertical pipe segment or a unique bracket fastened to the wall may be necessary in certain situations. The hose (preferably transparent) should be connected to the safety valve’s output pipe before being lowered into a sewer or plastic canister. The first option is advantageous because you can always tell when the boiler is operating in critical mode while you are away because there is water in the container.
Conclusion
Safety group in the heating system
It is the responsibility of individual heating system users to make independent checks to guarantee the safe operation of heating equipment. Installing a security group in the heating system is necessary for this purpose, t. To. All devices will be fully functional since it will avoid undue strain and reduce the chance of fostering. This group consists of a collection of components that enable trouble-free network operation and working fluid pressure control.

The primary reasons behind a water supply system hydraulic blow
We previously discussed the causes of it as well as preventative measures for a hydraulic system in the heating system; in addition to this piece, we recommend that you familiarize yourself with the details by reading this article.
Design elements of the device
Any security group consists of these kinds of devices inside a metal case:
- safety valve;
- manometer;
- air vent.
We will ascertain the composition and function of every component.
Element No. 1. Supporting valve
The purpose of this kind of valve is to shield the heating system from pressure that is too high. This device is made to work with a specific pressure indicator; when that indicator is exceeded, an operation is initiated and any excess is disposed of. In theory, an expansion tank is used to compensate for pressure loss during heating. As the liquid warms up, the excess heat enters the tank, maintaining a constant pressure within the network without causing any damage to the system itself. The working fluid’s total volumes stay constant, which is characteristic.
However, occasionally the tank stops working. It is specifically for situations like these that a protective valve that removes extra fluid from the network is needed. Connecting the hose that is visible in the sewer is required to prevent water from spilling onto the floor and into the thread. Another inference that can be made from this is that the boiler room has to have a sewage system.
Note: If antifreeze is being used as a coolant in this situation, you should never pour it into the sewer system.
There is a handle (typically red) in the upper portion of the valve that is used to check the device’s performance. To accomplish this, simply turn the handle in the direction shown by the arrow, and the water should start to flow. If the water stops flowing before the handle is released, the valve is functioning properly. If the water flow persists, you will need to open and close the valve multiple times before things usually return to normal.
The valve needs to be changed as soon as possible if the water does not want to stay in it. If the valve is not "sitting" firmly enough in the saddle, another liquid may escape. It is important to remember that fuses work on the assumption of different pressure indicators, so the pressure at which your heat generator is designed should be taken into consideration when selecting a specific option. A three-atmosphere valve, for instance, is required for a private residence.
However, what would happen if the necessary fuse for the heating system’s security group was missing from the sale? In these situations, it is preferable to buy each device separately and gather the group yourself when you get home (more on this a little later).
Element No. 2. Manometer
The manometer’s primary function is to modify the highway’s pressure. For optimal operating comfort, they can be made to accommodate different pressure indicators, just like the fuses mentioned above. You only need to closely examine a device’s body to learn about its testimony (usually this is quite enough).
The device needs to be made for a maximum pressure of 4 atmospheres because private homes typically have pressures of 2 or 3 atmospheres.
The device itself has two arrows: a red one that is required for control and a black one that indicates it is also operational. It is necessary to manually install the second arrow on the designated mark. Generally, floor installations for heat generators require two atmospheres; however, the technical documentation specifies the specific indicator. Additionally, if the black arrow "went" redder while operating, it meant that the pressure had gone up too high.
Element No. 3. Automatic air vent
The security group must be installed in the upper part precisely due to the air vent-the fact is that it should be located at the highest point, where air bubbles are directed. In fact, this is another variety of Maevsky crane, capable of functioning on the machine. You do not need to tighten or unscrew it, t. To. Air is assigned in automatic mode. In the case of an emergency, this device is truly indispensable. For example, a temperature controller can suddenly stop working, which is why the working fluid in the heat generator can boil. And at this time, air may be released, which with a 100 % guarantee will violate the integrity of the entire system.
Additionally, it will be carried out to divert air with the assistance of the air vent, which is a component of the heating system’s security group.
Note: A professional installation is necessary for the security group to operate normally. The smallest mistake made during installation robs a group of its meaning, and in an emergency, that might not function at all.

The way that such a group operates
Imagine now, purely hypothetically, that the coolant’s thermal expansion—which is crucial to the operation of the entire heating system—was not compensated for by the expansion tank for any reason. In this scenario, the highway’s pressure will start to increase. Subsequently, the protective valve is activated; the spring inside is compressed because it can no longer contain the working fluid, leading to the valve and pressure being released.
How does all of this occur?
- The first phase. Excess air go through an air vent.
- The second phase. Excess working fluid descends through a special discharge in the protective valve.
Note: A special hose or tube is connected to the withdrawal, which needs to be brought to the sewer system, to prevent random burns when the valve is suddenly triggered and the excess fluids.
The main varieties of security heating groups
As was already mentioned, security block configuration might be the most varied. For instance, there is one such choice.
Alternatively, consider this alternative where every component is contained within a single case.
A couple more choices.
There are numerous alternatives for putting the security group on sale, but since all of them operate on the same principle, external indicators have no bearing in this situation. Again, you should select a specific model based on the pressure indicator that the protruding valve and pressure gauge are made from.
After discussing the primary categories, we will now familiarize ourselves with well-known producers and the approximate price ranges of their products.
Where to install a security unit?
With a wall-type heating boiler, you don’t need to worry about anything because the security group is already present either inside the boiler or on the back wall, indicating that the manufacturer has already taken care of everything.
However, blocks for floor-type boilers need to be bought separately and installed manually. Where exactly is that? At the closest possible distance from the heat generator—that is, no more than 100 to 150 centimeters—on the feed pipe. The manometer needs to be positioned such that all of its testimonies are easily observable. Prior to beginning installation work, it is also essential that the working fluid, which emerges from the protective valve, be made visible.
Features of installation
Initially, you should have a quick conversation about closing ball valves (you will learn more about this later). It is important to arrange a heating system carefully so that any component that breaks down can be quickly replaced or, if necessary, repaired without draining the coolant from the system as a whole. The installation of ball valves serves this function.
Say there is a battery leak. In this instance, all you have to do is block the cutting taps both before and after the battery, and then take it out. After this, the heating system will keep on working, which is crucial if the weather is sufficiently chilly. Should these cranes not exist, you will need to remove all of the working fluid from the roadway. More importantly, the system won’t function at this time, so this will take a lot of time and effort.
It is advised that these cranes be installed on all heating appliances, including the circulation pump, batteries, membrane tank, and so forth.
And the heating system now has a safety group. Here is a quick guide that will tell you which order the block should install in.
Step 1: The security group needs to be installed on the feed pipe, no more than 150–100 centimeters away from the boiler used for heating.
Step 2: Many people install this device without the necessary knowledge, placing it between it and the heat generator and shutting off the taps—or, alternatively, going straight to the group. This is how they explain it: a boiler that breaks down is easily replaceable or repaired. Here are two examples of how cutting cranes can be installed incorrectly.
The cranes in each example are not adjusted correctly, and if the heat generator breaks down, the seller will not honor the guarantee because the equipment was not installed properly. Cranes positioned in this manner raise the possibility of the system overheating, which could cause the boiler to malfunction.
Step 3: The cranes ought to be positioned behind the security group with skillful installation. That’s correct, but in this instance, nobody will turn you down.
How to Connect a Security Group in a Video
Production of a security group at home
Many are curious as to whether one can personally form such a group. It is feasible, but you will have to buy each component separately and connect them with tees, adapters, and other connectors. The block of the block can be cooked using polypropylene pipes and fittings; this will be far less expensive than a brass "store" option.
However, keep in mind that the polypropylene security group cannot be installed in batteries; rather, it can only be placed in highways with low working fluid temperatures (such as "warm floors"). This is because heating the liquid to ninety-five degrees will cause polypropylene to be destroyed, with potentially highly unpredictable results.

Safety group in the heating system
Accidents can be prevented with the aid of the heating system’s control devices.
When installing autonomous heating, it is necessary to take care of the safe operation of the system. Professional installation, as well as control devices that will give a signal about problems will be able to ensure such work. Automation of control over the operation of the heating system is carried out using a group (or block) of security. It is easy to guess that with automated control over the state of the heating circuit, the risk of failure of expensive components is reduced. Especially relevant is the installation of a security group for closed heating systems. In some models of boilers, it is installed initially, in others it is mounted optionally, and sometimes acquired and mounted additionally. Let us consider in more detail what a security group for heating is, what does it consist of and how correctly mounted in the circuit. It is important not only to purchase equipment, but also to correctly install it.
To make sure your home heating system runs safely and effectively, installing a security group is an essential first step. By keeping the system’s temperature and pressure within safe bounds, the security group guards against possible dangers like overheating or excessive pressure buildup. Usually, it has safety features like an air vent, a pressure gauge, and a pressure relief valve. Together, these parts protect the boiler and pipes from harm, extending the life of your heating system and improving its dependability to save you money on future expensive repairs and improve the heating efficiency of your house.
What is a security group for heating?
Several control devices in the general building comprise the security unit.
A security unit is made up of multiple devices combined into one building. Usually, galvanized steel is used to make the case itself. Additionally, the gadgets are fitted to a brass base. Theoretically, fasteners can be made of any appropriate material for the construction and installation of a security group for heating with your hands. All that matters is that it endure the operating pressure and temperature within the heating system.
This device is designed to control the pressure inside the heating circuit. Sometimes the manometer is combined with the thermometer and has two scales – pressure and temperature. If it comes complete with the boiler, then it is unequivocally compatible with it. If it is purchased additionally, for the installation of a security group in the heating system, then you need to pay attention to the compliance of its scale parameters of the boiler. Household boilers are usually designed for working pressure in 1.5 – 2 atmospheres. Accordingly, do not purchase a pressure gauge with a scale of up to 50 atm. At least simply because the divisions will be very small, and you simply will not see a small pressure drop, which, nevertheless, may be critical for work.
Air vent
It is fitted into heating systems to release trapped air and stop air plugs from forming. It is advisable to install an automatic air vent in a security group for a heating boiler, even if there are Maevsky cranes on each radiator. First off, if the air bubbles have gathered elsewhere in the pipeline rather than in the radiators, this will assist in eliminating the contour. Furthermore, in contrast to Maevsky’s cranes, air removal from the system is accomplished automatically, instantly, and without human involvement with its assistance.
Obstacular membrane valve
If needed, the safety valve will assist in resetting the pressure.
Designed to reset excess coolant, for example, in the case of boiling. Particularly relevant when installing a security group in a closed heating system. Performs a very important function, as it helps to avoid emergency destruction and equipment breakdown. Indeed, as a result of exceeding the maximum permissible working pressure inside the system, pipe rupture, depressurization, as well as failure of the most important link – a heating boiler can occur. The amounts that will have to be spent on the repair and restoration of the system, and the price of the safety valve is not comparable. Therefore, the question is whether to install a membrane valve in a security group for heating is usually not even discussed. Definitely – yes.
To guarantee the effectiveness and safety of a home heating system, a security group installation is an essential first step. By controlling pressure and temperature, this configuration helps to avoid situations that can harm the system or jeopardize household safety. In essence, it serves as a safety measure against the frequent mishaps associated with heating system operation, like excessive pressure buildup or overheating, which may result in expensive repairs or even dangerous circumstances.
The installation of a security group improves the heating system’s performance and extends its lifespan. It guarantees efficient and even heating throughout the house by preserving ideal operating conditions within the system. When the system doesn’t have to work as hard to maintain the desired temperature, comfort and energy costs may both noticeably improve. Furthermore, it’s impossible to overestimate the comfort that comes from knowing your system is guarded against unforeseen malfunctions.
It’s crucial for homeowners thinking about installing a security group to speak with an expert to make sure it integrates correctly with your current system. The knowledge and skills of a certified technician are essential for choosing the appropriate parts and completing an installation that conforms with regional safety codes. By taking this precaution, you not only guarantee the stability of your heating system’s operation but also the validity of any warranties associated with it.
In conclusion, installing a security group in your heating system is a wise choice that benefits from increased safety, cost effectiveness, and efficiency. It’s an investment in your house that will pay off in the long run by keeping your heating system operating efficiently and your house safe and comfortable. A security group should unquestionably be taken into account as part of your overall heating strategy for anyone wishing to maximize their home heating system.
