For many homeowners, keeping their house warm and comfortable throughout the winter is of utmost importance. While having a heating system that works is necessary, making sure it does so effectively is also crucial. Installing a bypass is one way to increase your heating system’s efficiency. We’ll discuss what a bypass is and its advantages for your heating system in this article.
Firstly, let us define what a bypass is in clear terms. In essence, a bypass is an additional path in your heating system that permits hot water to pass through specific regions when needed. By doing so, you can ensure even heating distribution throughout your house by controlling the temperature in various areas. Consider it your heating system’s relief valve, guarding against any problems that might result from high pressure or temperature fluctuations.
What makes a bypass an attractive addition to your heating system, then? Yes, there are a number of advantages to doing this. First off, by using less energy, a bypass can help your system operate more efficiently overall. Allowing hot water to go through zones that don’t need to be heated will help you save energy and eventually reduce your utility bills.
Additionally, a bypass can increase how long your heating system’s component lifetime is. You can lessen the amount of wear and tear on your boiler, pumps, and other parts of the system by preventing overheating in specific places and making sure that hot water flows through the system more consistently. Long-term, this can save you time and money by reducing the need for repairs and replacements.
You can also have more control over the temperature in different rooms of your house by installing a bypass. Through the use of a bypass, you can adjust the heating distribution in rooms that are prone to extreme heat or cold, resulting in the best possible comfort throughout your living area. Furthermore, thanks to technological developments, you can now remotely control and keep an eye on your heating system from your tablet or smartphone with smart bypass systems.
To sum up, installing a bypass on your heating system is an easy yet effective method to increase comfort in your house, increase efficiency, and prolong the life of your equipment. A bypass is definitely something to think about if you want to lower your energy bills, have more control over your heating system, or just make sure that the temperature in your house is constant.
Why is a bypass
A bypass is a guide, a regular highway segment that ought to be erected at the circuit’s essential crossroads. It is important to remember that single-pipe schemes are the only ones that use the bypass for heating. A single highway is used for coolant circulation in a single-pipe heating circuit, whereas two highways are used in a two-pipe system. It begins and ends in the boiler room, where the water travels through the radiator chain, transferring some of its heat to each one.
The separation of the feed and return flows is the primary feature that sets apart a two-pipe system. Thus, in a two-pipe heating system, bypass is just unnecessary. The feed and return in a single-pipe circuit, however, are one single stream and cannot be separated. The circuit is set up in contours with a single pipe that can be found in various planes:
This means that the heating system’s bypass installation is likewise unique. In structures with multiple stories, vertical contours are installed. Horizontal: in apartments and single-story homes. Examine the contour’s behavior at various installation points to comprehend its basic working principle. Where can one install a bypass?
- on the pump, which oven the flow of the coolant;
- on radiators.
In both scenarios, the bypass route ensures that even in the event that the aforementioned equipment breaks down, the heating circuit’s circulation continues. What does the heating system’s bypass mean? By using this reserve channel, the coolant keeps circulating along the curve, preventing pressure surges in the heating system. Let’s examine the counter’s working principle for each of the aforementioned installation options in turn.
Installation on the pump
Circulation pump bypass using a ball crane
Why is there a bypass in the heating system near the location of the installed electric pump? It will be stated, more accurately, that the pump is mounted directly on it. This is done by placing an electrical supercumber in a gravitational circuit, where gravity acts as the circulator. As a result of the increased flow rate, the contour’s efficiency rises. This is because the coolant reaches an extreme radiator with reduced heat losses at a faster speed.
Installing a bypass for the circulation pump comes in two flavors:
- on a new circuit;
- on the already existing contour.
There’s no installation variation. The presence of shut-off valves between the rod pipe on the central highway is what you should be aware of. This is required to prevent the creation of the reverse flow and to ensure that the coolant passes through the bypass for the circulation pump.
It is imperative to precisely install the ball valve—instead of the check valve, as some plumbing systems do.
We will examine how it functions in stages to comprehend why:
- When the pump works, it gives the coolant acceleration;
- Water from the maintenance enters the highway and begins to move in both directions;
- In one direction (the necessary) it goes unhindered, and in the second side it turns onto the check valve;
- The valve closes and thereby prevents circulation in both directions.
In other words, because the coolant behind the pump will be moving more quickly, the water after the pump presses the valve harder against the plate than it did before. Anticipatedly, the coolant stops crushing on the check valve and does not overlap it when the pump is turned off. As a result, the water on the highway is able to flow naturally without entering the circle. In actuality, a check valve bypass for heating does not function as needed.
The truth is that a strong hydraulic resistance of one meter is produced by the check valve plate. The coolant in the gravitational circuit will simply stop circulating because it cannot tolerate such a high valve resistance.
Thus, you must realize that installing the pump on the contour will not make sense before installing the bypass in the heating system with a check valve. Due to its great success, it was able to be installed right next to the highway, consciously forgoing the option of having the heating circuit operated independently. In this situation, do I need a bypass in the heating system? As it happens, the answer is no.
You can regulate the direction of water circulation along the contour by installing a regular ball valve in place of a check valve. Now let’s examine how to add a bypass to a heating system that will have a pump installed on it. This plan is made up of distinct components:
- carving nozzles that are welded into the highway;
- ball valves – installed on both sides;
- corners;
- Carriage filter – put in front of the pump;
- Two Americans, thanks to which the pump can be removed to check or repair.
It’s crucial to pay attention to the pump’s proper location if you manually create a bypass in the heating system. The impeller’s axis should be horizontal, and the terminal box should be visible. The terminal box’s location can be adjusted by unscrewing the four bolts on the case if, after proper installation, the cover points downward. This place is required to remove coolant in the event of a leak and to allow unrestricted access to the terminals that connect the power.
Installation on the radiator
Turn off the heating radiator.
The bypass in the one-pipe heating system is installed on the location of the battery so that water can freely flow along the contour in the event that the radiator’s circulation is stopped. Two pipes are used in the vertical scheme to connect the radiator and riser. Installed in front of the battery, the bypass on the heating radiator serves as a link between these nozzles. In order to eliminate the possibility of human error or the potential for circulation obstruction in the case of a crane malfunction, there shouldn’t be any shut-off valves situated between the central highway and the contour.
The counter’s purposes, which are situated in front of the radiator:
- ensuring continuous circulation along the main ring of the circuit;
- Regulation of the temperature of the coolant.
Coolant travels along radiators in single-pipe contours, contributing to the stream and providing some of the heat. As a result, the coolant gets slightly colder in each radiator after it.
By installing a heating by heating system, the battery’s temperature can be raised by combining the coolant from the central highway with the one that ran along it.
It turns out that the temperature will drop to roughly 70 degrees if it was 80 degrees before the first battery. When mixing liquids, the temperature of the total flow increases to roughly 75 degrees because the coolant that travels through the bypass does not carry this kind of heat loss.
Similar principles apply to the horizontal one-pipe heating scheme as well; the circuit is just positioned horizontally on the area beneath the battery. Simultaneously, the heating system’s desired bypass diameter must be selected for proper circulation.
Bypas diameter
The radiator’s bypass system’s pipe size scheme
Therefore, we already know why and where the heating system bypass is installed. Determining its ideal diameter is still outstanding. Due to varying requirements, the diameter of the heating system bypass in each case will vary, so we must take into consideration the options for installing it on the battery and the pump separately.
The diameter of the pump on the pump will be either the same or less than that of the main highway. In this case, how to make a fundamental difference in the heating bypass. Ultimately, its installation serves the sole purpose of allowing gravity to take over in the event that the pump is disconnected.
As a result, the highway itself cannot be constructed, and the diameter of the pipes that deviate from the contour is not important. Because circulation through the pump will be impossible when it stops working, the circuit will not alter the coolant vector even if the diameter of the highway is the same. Additionally, we just overlap the coolant path with a ball crane that is situated on the highway when we require water to flow through the pump.
However, the diameter of the bypas is crucial when installing them on radiators in a private home’s heating system. It ought to be one size smaller than the radiator-to-central highway nozzles. In this instance, the battery taps should likewise be smaller than the primary contour. How it functions
- water flows along the contour and reaches the site on which batteries are installed;
- Backing into the branching, the coolant changes the vector of movement in the direction where there is less resistance;
- part of the coolant continues to move as a former vector.
A small amount of water will fall into the batteries if the diameter of the pipes matches that of the circuit, lowering the radiators’ temperature. The battery’s circulation will completely stop if the pipes’ diameter is smaller than the contour’s diameter.
The coolant can travel along the radiator more vigorously when the diameter of the pipes is reduced in relation to the main highway. Water circulates throughout the battery at the same time, causing it to warm up uniformly.
Take the bypass device found in the polypropylene heating system, for instance. The cross section of the pipes that allow water to enter the batteries should be 25 mm if the main line has a diameter of 32 mm. In a scheme like this, the contour’s diameter should be 20 mm. In this instance, the coolant will travel along the required path with the least amount of heat loss up to the extreme battery. It will be simpler to balance the system in this situation.

The heating system’s bypass
Even the name of a technical device can be confusing and even frightening to an uneducated reader who finds it difficult to grasp the essence of the device.
All you need to do is understand the basic principles of how the device works and how its parts are supposed to work together. After that, everything should become clear and easy to understand, making it feasible to assemble the device on your own without the assistance of an expert. The word "bypass" is used in all of the above.
The word unknown is not Russian. However, what exactly is a bypass in a heating system? Let’s solve it together. As it happens, bypass is just a standard pipe installed in the proper location along the heating system’s contour.
This is a type of bypass channel that allows the coolant to flow through the pipe in the event of an unanticipated issue with the heating or water supply systems. A bypass valve stops pressure changes in the pipeline system and all of the associated problems.
Wherever the bypass is applied
Only single-pipe systems, where the same pipe travels from the point of the initial heat supply along the radiator links and returns to the same point, but in a cooled form, with part of its heat spent along the path of follow, are recommended to use bypass.
One-pipe bypass heating system
The usage of bypas in a two-pipe pipeline system is not appropriate. The coolant flows independently of one another and travels through the system in various directions.
The bypass is installed in both horizontal and vertical pipeline systems; however, there are differences in how the device should be installed. Let me remind you that multi-story residential buildings typically have a vertical pipeline system, whereas buildings with one story or less typically have a horizontal pipeline system.
In essence, the bypass functions as a circuit jumper, which is a specific-sized pipe used to connect a radiator to a single-pipe heating system or to power coolant circulation pumps.
Bypas ensures the system functions even in the event of an electrical power outage when it is installed and connected to the circulation pump.
The bypass also functions as a heat regulator when it is connected to a heating radiator. T.To. He channels "excess" water away from the radiator. The diameters and lengths of bypasses vary, and they include connecting reinforcement elements.
The primary purpose of this device, regardless of bypass size, is to guarantee the continuous operation of the heating and tap system in the event that the heating radiator or circulation pump needs to be replaced.
In this instance, the system keeps running because the heat carrier supply pipe’s diameter is greater than the eyeliner’s at the radiator’s input and output.
Bypas is also responsible for ensuring that the coolant distributes its heat evenly throughout the batteries without dropping below the required temperature. The coolant in both horizontal and vertical pipelines will direct the majority of its heat toward the initial radiators in the event that the devices are not installed.
An extra channel that connects the feed pipe and the reverse pipe allows water to circumvent the battery in order to stop this from happening.
Radiator baypass with thermostat
Perhaps a brief explanation of the "Bypass" device should be given here. It won’t be difficult for someone with some plumbing knowledge to understand this device. And even easier, I would say, for those who are only attempting to grasp the fundamentals of this science.
The heating radiator’s bypass
If you reside in a multi-story building, you should be aware that there is a jumper located between the two horizontal pipes that run from your heating radiator to a riser in the wall.
This is the same bypass; it cannot yet be referred to as a bypas because it lacks specific locking cranes. However, after they—these taps—are installed, the bypas resumes its regular operation. In total, there ought to be three taps.
This crane is mounted on the pipe itself if your home is equipped with a modern heating system. The crane No. 1 is positioned where the jumper and a reverse-orientation pipe meet if the heating system is antiquated, as is the case with buildings from the Soviet era.
Integrated into the contemporary heating system is a ball valve. Additionally, t.n. tee was a three-way crane in the past. The sole purpose of this crane, regardless of where it is placed, is to completely shut off or severely restrict the water supply to the system in the event of a variety of emergencies.
They are mounted on horizontal pipes that go behind the jumper and heat radiators: tap No. 3 is mounted on the pipeline supply pipe, and crane No. 2 is mounted on the reverse orientation pipe.
These taps overlap, ensuring that you won’t suffer the unpleasant effects of this fairly common occurrence if there is an unexpected water leak.
Aluminum radiator bypass
I hope it is now evident to you why the jumper itself serves no purpose, why these cranes are mounted on the pipes, and how many of them there should be.
Assume that the jumper does not have crane No. 1. In this scenario, you will leave your neighbors without heat from above and below in the event of even the smallest emergency—blocking the water in your apartment. If the crane is installed, the heating systems of other residents of your home will continue to function normally and your neighbors won’t be prevented from receiving heat.
Let’s now review some findings regarding the bypass’s practical applications, degree of necessity, and functions.
In this instance, the water system’s bypass is used:
– installing water meters; – installing the pumping system.
Thus, the bypass serves as the jumper’s sole performer in the watering system.
Regarding the bypass buds that are installed in the heating system, they are more numerous and significant in this context. In the case of an emergency, the bypass in the heating system serves as both a coolant temperature controller and a bypass channel for the coolant. How this occurs was previously mentioned.
How to construct a hand-made backpass for a circulation pump
Is it feasible to construct a bypass on your own even if you lack the necessary plumbing knowledge and experience? It turns out that’s feasible, but we’ll deal with you jointly and on an orderly basis from now on in this process.
The circulation pump’s baypass
If your pump is on the heating line, you must first remove it and rebuild the highway in a slightly different way by increasing the space between the thread ends that the pump is attached to.
Install ball valves on both sides of the pump and position a tee of taps whose diameter precisely matches the pipeline’s diameter behind the pump.
I would like to call your attention to the fact that tees are typically made of metal. However, if your tee is made of polypropylene, you will need to insert special combined carvings with carvings or collapsible couplings from "Americans" before installing the crane.
It’s time to try on your knot now. Cut a section of pipe to the appropriate length and install the assembled knot in the desired location. This can be accomplished by disassembling the completed node into its component parts, turning off the pump, and joining the two pipeline sections to the main pipe. Install the pump and grab the water pipe after that.
The pipeline needs to be raised high enough to avoid touching the pump. After that, it needs to be securely connected or oriented so that two nozzles meet in the middle, and a crane with a jumper needs to be installed. Similarly, you can DIY the assembly of the bypass for other plumbing devices as well as the heating system’s circulation pump. We view the film.

What is a bypass in the heating system
The term "Bypass" is probably familiar to anyone who has interacted with engineering networks in any capacity. To put it simply, this is a circuit that water can flow through under different conditions. We will examine these situations and determine the bypass’s function in the water supply and heating system in this article. If needed, we will also demonstrate for you how to correctly mount it using our hands.
A practical upgrade that improves system efficiency and aids in maintaining uniform heat distribution throughout your house is adding a bypass to your heating system. When radiators or heating zones are turned off, a bypass line allows water to go through an alternative path, avoiding pressure buildup and undue boiler wear. This configuration not only increases the lifespan of your heating system but also gives you the freedom to regulate heat output by room, so you can maintain a comfortable interior temperature while using the least amount of energy possible. Additional piping and valves must be installed during the process, which is best done by a professional to guarantee efficiency and safety.
Baypas functions in the heating system
To be clear, the bypass is a pipeline intended to be used as a water duct to avoid a specific portion of the line where equipment is installed. It appears in two locations in heating schemes:
- in single -pipe systems as a jumper on radiators;
- on the camshaft of water warm floors.
As you are aware, heat transfer from the first battery in a single-pipe heating system influences the operation of the next, and so on. This holds true for schemes that are horizontal and vertical. The radiators will turn on in series if the heating system’s bypass installation is not made. Consequently, the first one will choose the highest temperature, the second will choose everything that’s left, and the third will only be defended by chilled coolant.
The feed and return near each battery are connected by a jumper whose job it is to direct some coolant away from the radiator in order to prevent this from happening. In this instance, the bypass principle aims to lessen the reliance between the nearby and distant heating devices by transferring a portion of the heat to each. The following figure illustrates how this is accomplished:
Vital. The product is supplied in the vertical system depicted by the bypas so that the pipe’s diameter is smaller than the main line and is slightly off-axis. The intention is to stop the coolant from flowing past the radiator in a straight line against the force of gravity. The main pipe in the horizontal system functions as a bypass since it stays in the same place and has the same passing cross-section everywhere.
For batteries to receive consistent heat distribution and to be maintained or repaired, a bypass heating system is required. Simply cut off the two taps that are connected to the coolant’s input and output if you must disconnect and remove the heating device for any reason. After that, the water will pass through the jumper using the bypass route.
However, the purpose of the water floor collector’s bypass for heating is different. This circuit line has a three-way valve and is a component of the mixing unit. The node’s job is to heat the coolant to the proper temperature so that it can be supplied to the warm floors’ warming contours. As you can see, the water temperature in these contours stays below 45 °C, but it can reach as high as 80 °C in the supply line.
The three-way valve functions as usual, sending a limited amount of hot water from the system to a warm floor. The remaining coolant is recycled back to the boiler after passing through this automated bypass and combining with cold water from the collector. Due to the considerable temperature differential between the collector and the highway, the bypass line is always in use. It turns out that floor heating cannot operate normally without it.
Bypass in the boiler room
The bypass line is also required in the following two scenarios in the boiler cauldron circuits:
- like a bypass for a circulation pump;
- to organize a small circulation circuit for a solid fuel boiler.
Heating systems frequently have a pump installed on the bypass pipe, sometimes even without much use. The truth is that when the pump is turned off, a forced circulation heating system, whether single- or two-pipe, will never be able to operate. For this, she does not have steep slopes or larger pipe diameters. However, the purpose of the pump bypass is to allow water to flow freely in the event that the pumping mechanism malfunctions.
Thus, the recommendation is to turn on the bypass pump when connecting a forced circulation system to a boiler. The coolant will stop flowing if the unit is disconnected and removed, which is why the pump is installed in a straight line.
A system designed for the flow of water naturally is another thing. In order to boost efficiency, a bypass system with a check valve installed in a straight line is frequently installed in addition to the pump. As shown in the diagram, this enables you to instantly switch to natural circulation in the event that the electricity is cut off:
The pressure from the pump’s working side packed the valve from the reverse side, preventing a straight flow of fluid. To restore the convective movement of water, simply turn off the electricity or block one of the taps. This will eliminate the pressure and open the direct path to the coolant through the Bypas valve. The system will not malfunction if you safely remove the pump or clean the mud; instead, it will switch to a different mode of operation.
A small circuit circuit circulation of a solid fuel boiler with a mixing knot is, in fact, the final application for bypasses. Here, in order to prevent low-temperature corrosion on the steel walls of the firebox, the heat generator can be heated to a temperature of 50 º using a jumper that is connected to a three-way valve. The bypass circuit in this instance appears like this:
The basic idea is this: the valve keeps cold water from the system from entering the boiler until the coolant running through the backpass line reaches the necessary temperature. Subsequently, the valve opens, allowing cold and hot water to mix in the circuit. Consequently, condensation does not form on the furnace walls, and corrosion does not happen.
The water supply system still occasionally has a bypass. For instance, taking out a heated towel rail in the bathroom to fix it or replace it. There will be a great deal of inconvenience during its dismantling because it is connected to the DIA riser in an apartment building. It is simpler to plan ahead for this and use a crane to install a jumper when installing the heater.
How to install a bypass correctly
There is a bypass line as part of the warm floor camshaft equipment, but that is a different discussion. Regarding the jumpers on the one-pipe system, their installation is extremely easy and is already done during the system installation process because the system will not function properly without them. Installing a bypass line and circulation pump with your hands is not that much more difficult. It suffices to review the plan and keep a standard set of tools:
Suggestions. To avoid dialing each component individually, you can purchase a pre-made assembly assembly, as depicted in the figure below:
A heated towel rail requires no complicated installation or bypass. You can get metal and plastic pipes for compounds, as well as cranes, tees, and taps. The assembly is completed in line with the plan:
| Step | Description |
| 1. Determine the Bypass Location | Identify where the bypass should go, typically around a pump or valve to maintain flow when the main route is blocked. |
| 2. Gather Materials | Collect all necessary materials such as pipes, fittings, tees, and valves suitable for your heating system"s specifications. |
| 3. Turn Off Heating System | Ensure the system is off and fully cooled down to avoid any accidents. |
| 4. Install T-junctions | Cut the main pipe where the bypass will connect and install T-junctions at these points. |
| 5. Connect Bypass Piping | Measure and cut the pipes that will form the bypass loop and connect them using the appropriate fittings between the T-junctions. |
| 6. Install Valves | Install isolation valves on the bypass so that it can be controlled independently of the main system. |
| 7. Check for Leaks | Turn the system back on, allow it to reach operating pressure, and check all new connections for leaks. |
| 8. Insulate New Pipes | Wrap the new pipes in insulation to maintain efficiency and safety within the heating system. |
The flexibility and efficiency of your home heating system can be greatly increased by adding a bypass. Better control over the heating flow is made possible by this small addition, especially in systems where temperature regulation and balancing are critical. You can keep your home comfortable and possibly save money on energy bills by making sure your heating system runs efficiently and consistently.
Knowing the fundamental operation of your heating system and the areas where a bypass works best is essential to installing a bypass. This usually occurs where the system divides to service various rooms or appliances. As a safety measure, the bypass valve makes sure that the water flow can be changed or allowed to continue past specific points without impairing the operation of the entire system. In the event of a partial system shutdown or during maintenance, this is extremely helpful.
It’s crucial that homeowners thinking about this upgrade speak with an expert. Though the idea may seem simple, the actual installation calls for technical expertise to install additional piping and valves correctly as well as exact knowledge of your heating system’s layout. This guarantees that the bypass complies with regional building codes and safety regulations in addition to ensuring proper operation.
In general, anyone wishing to increase the efficacy and efficiency of their home heating system would be wise to install a bypass. By reducing needless pressure and wear, it not only makes controlling heat distribution and maintenance simpler but also increases the system’s lifespan. You can have a heating system that is more responsive and resilient with the correct configuration and professional guidance.
