Balance of a two -pipe heating system with your own hands

Ever pondered how to get the most out of your house’s heating system? Finding the ideal balance in a two-pipe heating system can make all the difference, regardless of whether you’re facing uneven heating or dramatically rising energy costs. Fortunately, you can take control of the situation and optimize your system for maximum comfort and efficiency on your own with a little know-how and do-it-yourself attitude.

The first step in attaining balance is comprehending the principles of a two-pipe heating system. A two-pipe system has separate pipes for the supply and return, in contrast to a single-pipe system, in which hot water travels through one pipe to radiators and returns through the same pipe. With this design, you can precisely regulate the hot water flow and guarantee even heating throughout your house.

Making sure that every radiator gets the appropriate amount of hot water to maintain a comfortable temperature is one of the main challenges in maintaining the balance of a two-pipe heating system. Unbalances can cause certain rooms to be overheated while others stay cold, which is uncomfortable and energy-squandering. Spending some time correctly balancing your system will get rid of these irregularities and provide uniform heating in every room.

Although the thought of balancing a heating system may seem intimidating, the typical homeowner can easily accomplish this task. With the correct resources and a methodical approach, you can confidently take on this project. You can use a variety of methods to fine-tune your system and attain ideal balance, from bleeding air from the system to adjusting radiator valves.

In this article, we"ll delve into the essential steps for balancing a two-pipe heating system all by yourself. Balancing ensures that every radiator in your house receives the right amount of heat, making your system more efficient and comfortable. First off, understand the basics: your system consists of a supply and return pipe for each radiator. Start by closing all radiator valves, then gradually open them one by one while measuring the temperature difference between the supply and return pipes. Adjust the lockshield valves until the temperature difference matches the manufacturer"s recommendation. Repeat this process for each radiator until they"re all balanced. Regular maintenance and monitoring ensure your heating system stays efficient and keeps your home cozy throughout the year.

Features of work with different types of wiring

The easiest heating systems to balance are those with one pipe. Everything is because the total duct through the binding bypass and radiator is constant and does not rely on the installed reinforcement’s throughput. Thus, in Leningradka-type systems, the focus is on the equation governing the heat released by the coolant in radiators rather than the duct balancing. To put it plainly, the primary objective of balancing in this situation is to guarantee that the water reaches the farthest radiator at a temperature that is high enough.

The idea behind two-pipe dead end systems is a little different. Every system radiator is a type of shunt that is placed later in the duct’s direction and has a lower hydraulic resistance than the others in the group. This means that while much less coolant is circulated further through the system, a sizable portion of the coolant flows through the shunt back to the heat unit. With these heating systems, the reinforcement’s capacity must be changed in order to precisely align the duct in each radiator.

Heating systems with two tubes passing through them don’t need to be balanced at all, but they also use a lot of material. The whole allure of the Tichelman loop lies in this: each radiator’s coolant circuit follows a nearly identical path, ensuring that the duct equivalency at every system point is automatically supported. Similar circumstances exist with radiation heating systems and water warm floors, where duct alignment is carried out on a common collector in accordance with floating consumables.

Temperature settings

Frequently, Uncle Vanya, the skilled welder, designed and assembled the system, and the homeowner has no design documentation. The only thing left to do is control the temperature of each battery.

In order to manually balance the heating system, you must install a specific valve, like the one in the picture, at each radiator’s output. An electronic thermometer that can measure the temperature on any surface is also necessary.

The process starts with the heating device that is the furthest away and has the strongest valve fully opened. A limited number of revolutions can be made on the remaining ones. For instance, if there are six batteries on one branch and the valve unscrews every five revolutions, we open the first radiator once, the second once, and so on, until the end. The goal of roughly balancing a private home’s two-pipe heating system is to maintain a constant temperature at each heater’s output.

Take a temperature reading on the valve’s metal body to accomplish this. If it’s low, open it; if it’s high, cover it slightly. In order to allow the temperature to stabilize following the change, the subsequent measurement needs to be taken ten minutes later.

Electronic system balancing

Temperature balancing is a laborious and drawn-out procedure. It is extremely challenging to accurately adjust complex heating systems in this manner. Using a smartphone with a specialized mobile application, extra electronics, and a circulation pump with balancing capabilities is much simpler.

  • a circulation pump with an appropriate function (in some cases, a removable head of a pump intended for balancing the system is installed on the existing pump);
  • smartphone and special software;
  • Wireless communication module installed on the head of the pump.

There are four steps involved in the electronic balancing of the system:

Preparatory steps include attaching a communication module to the pump and installing a specific application on a mobile device. measuring the pressure and consumption in each radiator or warm floor circuit, as well as entering data into the system (such as the number of heating devices, the area of heated rooms, the coolant’s temperature, etc.) (performed using a mobile application). Balancing valves are used to maintain system balance in accordance with the mobile application (valves). Taking the communication module apart and keeping the balance report that a mobile application created.

Rather than concluding, let me say this: accurate configuration of the working heating parameters is possible with proper balancing.

In addition to giving every room the most comfortable temperature, this drastically lowers the system’s operating costs.

Security Group

The three components that make up the security group are linked together, or to a single instance:

An emergency safety valve that permits you to increase the system pressure and dump excess coolant. Reset can be taken out and placed in a clear container (like a plastic bottle). This will increase the device’s security and alert users to an emergency (even if no one was home). Automatic air vents remove coolant from the air, which could cause the system to stop working if it’s heating up. A manometer gives you visual control over the coolant pressure in the supply line.

As soon as the security group exits the heating boiler, it crashes into the submitting highway. The main reason for doing this is to safeguard the boiler, which has the highest temperature.

The security group is positioned exactly vertically, even though it ought to be higher than the heating boiler.

Installing an extra automatic air discharge valve at the system’s highest point is recommended. During the refueling process, air will undoubtedly enter the system. This device will help stabilize system operation, prevent coolant stagnation from air accumulation, and prolong the circulation pump’s service life.

Debugging in automatic mode

A certain golden mean exists between the two previously mentioned approaches. Specialized machinery for hydraulic heating systems’ automatic balancing enables quick and highly accurate configuration. For these purposes, the Grundfos Alpha 3 "smart" pump—which comes with a detachable transmitter and a branded mobile application—is currently the primary technological solution. The equipment set costs roughly $300 on average.

What is the project’s main purpose? The pump has an integrated consumer and can communicate with a tablet or smartphone to process data exchanged between the two devices. The application functions as a guide, showing the user step-by-step what adjustments need to be made above various heating system components. Simultaneously, distinct rooms with the designated quantity of heating apparatuses are retained within the application database; various radiator kinds can be selected, along with their power, required heating standards, and additional information.

The procedure is incredibly easy to follow and fully explains the program’s algorithm. To measure zero consumption, all radiators must be disconnected from the system after mating with the transmitter and getting ready for work. Subsequently, open the shut-off valves on each radiator in turn. Simultaneously, the pump’s flow meter records duct variations and ascertains the highest capacity of every heating apparatus. Each radiator is adjusted separately once it has been added to the program.

Real-time locking valve setup is done on radiators. There is a good chance that the application will be able to operate in difficult-to-reach areas. To achieve balancing, the locking rod must be finely adjusted to the point where the system’s current consumption equals the amount suggested by the program. After working with each radiator, the application creates a report that includes information on all of the system’s heating components as well as the coolant consumption of each one. Following the balancing, the Alpha 3 pump can be taken out and swapped out for a different one that has comparable performance specs. released on

Why do balancing

All heating systems, no matter what kind, need to make sure that the batteries receive the precise amount of coolant needed for them to be able to heat the room. Furthermore, only the necessary amount of hot water must reach each radiator. In all circumstances, neither less nor, ideally, more. All people are aware, though, that more water will always choose the easiest route.

In other words, if the heating system’s hydraulic balancing is not done, the batteries closest to the boiler will receive the most heat, while the batteries farthest from it will receive almost none. Certain rooms are hot, while others are cold. Simultaneously, the boiler operates at maximum capacity rather than in an efficient and gentle manner. The figure depicting the heat distribution according to the system is shown below in two versions: one that is imbalanced and the other that is set up as it should be.

Hydraulic balancing is therefore required for:

  • uniform heating of all heating devices;
  • the work of the boiler in normal mode and energy saving;
  • In order to avoid the noise of large volumes of water flowing through nearby batteries with high speed.
