What is an elevator node in the heating system

Ever wonder how well your home’s heating system distributes heat to various rooms? The "elevator node" is an essential part of a heating system that makes this possible. This essential device makes sure that every part of your home has the ideal amount of heat by regulating the flow and distribution of hot water.

In essence, an elevator node in a hydronic heating system is a control point. Hydronic heating systems are effective and adaptable for home heating because they transfer heat through the use of water as a medium. By directing hot water from the boiler to various zones or areas within your house, such as particular floors or rooms, the elevator node functions as a traffic regulator.

Consider the elevator node as a dispatcher responsible for distributing the ideal amount of heat to every area of your home. Thermostats placed in different zones provide input to it. A thermostat will send a signal to the elevator node to open or close valves that regulate the flow of hot water when it senses that an area needs to be heated.

Precise temperature zone control is one benefit of incorporating an elevator node into your heating system. The elevator node lets you modify the temperature according to the needs of each individual room rather than heating the entire house at the same time. In addition to improving comfort, this zoning feature lowers energy consumption in vacant spaces by cutting back on needless heating.

You can maintain and maximize the comfort and energy efficiency of your home by making informed decisions based on your understanding of how the elevator node of your heating system works. You can extend the life and performance of your hydronic heating system by making sure this important part is operating correctly and efficiently.

Heating system elevator node: what is it

The primary heat supply networks have three modes of operation that are measured in degrees and look like this:

The feed temperature is indicated by the first value, and the opposite pipeline is indicated by the second. Due to energy loss from the frequently considerable distances to boiler houses, the number must be adjusted to account for outside weather. In order to reduce fuel consumption, these three options were created.

The purpose of the elevator node

This crucial component of the system is intended to reduce pressure and stabilize coolant temperature. The pipeline is filled with colder water from the heating circuit to carry out the process.

As per the widely recognized hygienic guidelines, the fluid in radiators must not surpass the 95-degree indicator. Here are some apparent details about this moment:

  1. The most heated devices in the apartment can harm the child after touching.
  2. Cast iron radiators in this situation will become vulnerable to mechanical damage and fragile, aluminum specimens can fail.
  3. Plastic pipes used in the wiring of the premises are not designed for very high temperatures and may lose aesthetic appearance.

They choose an elevator to stop these overuses of the heating main; apartment buildings cannot function without a component of this kind.


You should learn more than just the details about this component, which appears to be a kind of metal or cast-iron structure with three holes and flanges on each to connect the unit to the system that the elevator node is made of. I was much more intrigued by the internal structure, which requires that I first disassemble each component individually. It looks like this:

  1. Frame.
  2. Nozzle.
  3. Mixing camera.
  4. Innings.
  5. Reverse highway.
  6. Output to the system.

The maximum pressure is detected during the presentation when the diffuser’s exit pressure is lower, and the lowest pressure is detected in the rear system when the liquid temperature is lower. An upright jumper collides with a case at an angle of less than ninety degrees.

The scheme of the elevator node

Even though the device is fairly basic and resembles a pump that delivers a liquid under a certain pressure, the heating elevator cannot operate effectively without a proper binding. I will examine this topic in more detail.

The water that is the hottest enters the input pipe and advances because of pressure. Because of Sopl, an injecting effect is produced that forces the liquid into the receiving chamber and creates a discharge area.

Water is drawn out of the pipe, which is connected to the pipeline on the other side, as a result of the pressure dropping. These adjustments cause the coolant to enter the elevator’s neck, where hot and cold flow combine.

The heating unit scheme looks like this: the normalized water, which has been taken into account for all safety standards, is returned to the system through the diffuser and distributed through the radiators in the apartments.

The principle of operation of the unit in the heating system

The heating elevator’s working principle, in my opinion, is comparable to that of a water pump, which runs entirely on internal energy.

Because of its affordable and straightforward design, this element is used in the majority of heating points found in apartment building systems. However, it should be expected that every unit will function as intended, barring unforeseen circumstances that prevent work interruptions.

The heating elevator features three holes with fastener flanges: the first connects to the supply pipeline, the second supplies liquid to the radiators, and the third receives the opposite flow. The pressure differential between the supply and reverse flows must be greater than the hydraulic resistance of the heating system in order for the network to function properly.

Elevator with automatic adjustment

Because of its reliance on outside sources, I do not think this kind of device is as practical as it can be, but it is a very modern device that merits consideration. The design calls for an automated adjustment mechanism to replace the nozzle’s section.

An elevator node’s operation is linked to a mechanism inside the elevator casing that was created specifically for this purpose. Depending on the system’s liquid temperature, this part is in charge of causing the throttle needle to move forward and backward.

The lumen is impacted by the mobile element in the snot, which modifies the coolant supply and consumption. Variations in the liquid’s patency control the heating system’s water movement velocity in addition to the pipes’ internal temperature. This results from the coefficient changing when hot and cold streams are mixed together. I explained to you why the main pipe’s temperature is fluctuating due to the heating elevator scheme.

It’s also crucial to keep in mind that you can control the pressure in the apartment’s pipes and radiators by using an essential component.

The device modifies the coolant in the heating circuit by directing the stream. Since the device’s design calls for the circulation of fluid, effective additions like distribution units frequently go there. These kinds of devices are only required in apartment buildings where multiple consumers reside concurrently.

Water is distributed by a collector or comb; once the coolant from the automatic elevator assembly enters this container, it exits the resident rooms via a number of outputs. The system pressure is unaffected by such manipulation; it stays constant.


Despite all of its advantages, the thermal unit’s design and the device itself have some drawbacks, which should be noted. These include:

  1. The dimensions of the components of the device are difficult to calculate, but if this is not done, then to ensure maximum productivity will not work.
  2. Providing the pressure difference on two highways, it is necessary to adhere to an indicator not exceeding 2 bar.
  3. For regulation, it is necessary to equip the unit with an electric drive.

The primary issue with the operation of the elevator node of the heating system, in my opinion, is that not all models of the device have such devices, which makes it necessary to adjust the nozzle’s diameter in order to control the temperature.

Technical characteristics of standard models

There are seven different types of structures found in factory specimens, each with a unique number and varying sizes. Two factors need to be considered in order to properly select a suitable solution and prevent issues during crimping: the diameter of the nozzle and mixing chamber.

With the second component, things are easier because the case is detachable and can be changed if needed. There are two variations of these actions:

  1. Details of the part after a certain time (development of abrasive particles).
  2. Changes in the coefficient of mixing, which is necessary to increase or reduce the temperature of the coolant.

I discovered a fascinating fact about how elevator units work: the diameter is calculated independently, so it’s common to find no mention of the nozzle section in the technical specifications. To precisely determine the size for a given heating system, the mixing and engineering chambers receive the most attention.

Calculation and selection of an elevator

With the aid of unique formulas The diameter of the mixing chamber must be calculated first, followed by the selection of the required heating elevator number and the nozzle size. Uncomprehensible kilocalories should be converted to common units right away; this is typically done by turning them into bars.

There is a formula for calculating the millimeters that make up the elevator nozzle’s narrow section. Although all of the operations seemed enormous when I looked at the notebook for records, the calculations were not difficult for me. Once the pressure at the central line exit has been determined, it is useful to use a different formula to find a diameter. I should be aware, though, that the outcome will be given in centimeters.

Installation of an elevator in the system

This device is typically found in the basement of the home, but before beginning any installation-related modifications, the space is examined for subtleties like:

  1. Lack of temperature lowering below 0 degrees Celsius.
  2. The room should be covered.
  3. The presence of exhaust ventilation, since after the formation of condensate on the pipes of condensate, the unit will quickly fail.

Models with integrated automatic mechanisms require a constant electricity supply; as a result, they will be dangerous if you don’t install an independent power source.

There will be many unpleasant moments if the temperature adjustment process is stopped when the supply of a resource that is essential to the resource’s operation is cut off. Condensation rectifiers must be installed in order to prevent voltage differences.

In conclusion, an elevator node in a heating system is an essential part that makes it possible for heat to be distributed effectively throughout a multi-story building. This node essentially serves as the entry point for hot water entering the building’s heating system from a central heating source, such as a boiler. From there, the hot water is routed through different pipes to different floors or zones within the building.

An elevator node’s main function is to control and balance the hot water flow throughout the structure, making sure that each floor is heated to the proper level based on its unique needs. Even in big or intricate buildings, the elevator node contributes to the maintenance of comfortable temperatures throughout the building by managing the distribution of heat.

The ability of an elevator node to control hot water flow in accordance with the heating requirements of various building areas is one of its primary features. Heat is directed to areas that require it most through the use of pumps and valves that modify water flow rates. Reducing operating expenses and maximizing energy efficiency depend on this flexibility.

Furthermore, safety features to guard the heating system against problems like pressure variations or abrupt temperature swings are frequently included in elevator nodes. By reducing the possibility of system damage and ensuring dependable operation over time, these safety features help reduce the chance of heating supply interruptions.

Conclusively, comprehending the function of an elevator node is crucial for the design and upkeep of efficient heating systems in buildings with multiple stories. Elevator nodes make a major contribution to the overall comfort, energy efficiency, and longevity of a building’s heating infrastructure by effectively distributing heat and controlling water flow.

In the realm of house heating and insulation, understanding the concept of an "elevator node" within a heating system is key. Essentially, an elevator node serves as a vital link between different floors or sections of a building, allowing hot water circulated from a central heating source (like a boiler) to be efficiently distributed throughout the building. This node regulates the flow of hot water to various parts of the house, ensuring each area receives the appropriate amount of heat. By controlling water pressure and temperature, the elevator node helps maintain consistent warmth across all rooms while optimizing energy usage. Essentially, it"s like a traffic controller for heat distribution, ensuring that every part of the house stays comfortably warm without wasting energy. Understanding this component is fundamental for anyone looking to enhance the efficiency and effectiveness of their home heating system.
