The effectiveness of our heating systems is essential to maintaining a warm and comfortable home. A horizontal two-pipe heating system is one common way to heat homes. The purpose of this system is to provide comfort during the cold winter months by distributing heat throughout the house in an even manner.
But how does this system operate, and what is the significance of hydraulic calculation? Let’s dissect it. Hot water is delivered from the boiler to the radiators via pipes that are parallel to one another throughout the house in the horizontal two-pipe heating system. Here, balance is crucial. Hydraulic calculation allows us to maintain the perfect balance of hot water for each radiator, ensuring a constant temperature.
In essence, hydraulic calculation is the science of figuring out pressure losses and flow rates in a pipeline system. To guarantee uniform heating throughout the house, it entails figuring out the best flow rates for each radiator in a horizontal two-pipe heating system. The size and quantity of radiators, the length and diameter of the pipes, and the required temperature in each room are all taken into consideration during this process.
What makes hydraulic calculation crucial, then? Now picture a situation where certain rooms in your house are excessively hot or cold. This imbalance wastes energy and raises heating expenses in addition to having an impact on your comfort. Your heating system’s hydraulics can be accurately calculated to prevent problems like these and guarantee smooth operation.
Additionally, hydraulic calculation increases the longevity of your heating system. Each radiator works more effectively and puts less strain on the system’s components when it gets the proper amount of hot water at the right pressure. By doing this, you lower your heating system’s environmental impact in addition to saving money on repairs and upkeep.
To sum up, hydraulic calculation plays a crucial role in the design and upkeep of a two-pipe horizontal heating system. Ensuring appropriate flow rates and pressure levels contributes to uniform heating, enhances energy efficiency, and extends the system’s lifespan. So, don’t undervalue the significance of hydraulic calculation when building a new home or updating an old heating system.

Where to start calculating hydraulics for a horizontal two -pipe heating system?
In a literal sense, you must begin your computations "from the stove." The two-pipe heating system’s hydraulic calculation can only be carried out once it has been decided which fuel the installed boiler will operate on.
Following that, you can start the actual computations, the primary objective of which is:
- Determination of the required number of heating devices and pump power.
- Clarification of the amount and total length of the pipelines, their required diameters.
- Determination of probable heat losses.
The heating scheme that was previously drawn on the scale, to which all of its components should be applied to the last tap, is the basis for all calculations. You can easily find basic formulas, specialized calculating tables, and the appropriate program online. In addition, you will need it.
The procedure for completing calculations
On specialized websites, there is an example of a hydraulic calculation for a two-pipe heating system.
We shall examine the series of computations under the following supposition in this article. Permit us to install a two-pipe horizontal heating system in our facility. When arranging from private residential buildings with a total area of up to 150 m2, the specified option is most frequently found.
In the case that is indicated, you should use the CO pipeline’s ring when it is operating at its maximum load as the calculated object.
The necessary pipeline segment and the possible pressure loss throughout the circuit are then identified. Next, we calculate the optimal heating device surface area by taking into account the entire surface area.
The program and table mentioned above are used to perform the hydraulic calculation of the two-pipe heating system, which includes all of the calculations mentioned above. The outcomes will aid in determining:
- All probable resistances that may take place in the future heating circuit;
- accurate temperature characteristics;
- hot water consumption in each part of the system.
Actually, you can optimize your plan even at the design stage thanks to the hydraulic calculation of the horizontal two-pipe heating system. What will shield against overindulgence and unavoidable changes otherwise.
Calculating the system’s hydraulics while accounting for the pipelines that are currently in place.
The scheme of the heating system with an open expansion tank and a built -in circulation pump
The hydraulic calculation for this horizontal two-pipe heating system will necessitate an understanding of the primary hydraulic system parameters, such as the resistance generated by the hydraulic reinforcement and the pipes themselves, as well as the hot water consumption and movement speed. The corresponding table and the unique program that was previously mentioned are also essential.
Let us explain why it is impossible to overlook these indicators. The hydraulic resistance indicator in the pipes will automatically increase if the flow rate of hot water through them increases. Both of the aforementioned indicators will rise at the same time as hot water consumption increases.
The internal diameter of the pipelines and t.P. are inversely proportional to the coolant indicator’s movement speed, ceteris paribus, of the main hydraulic resistance.
Through the process of analyzing the identified parameter relationships, the hydraulic calculation of the two-pipe horizontal heating system provides a trustworthy image of the future dependability and efficiency of the chosen heating scheme.
And as a result, you will be able to lower the price at which you buy the necessary supplies and parts. It is crucial to remember that all hydraulic characteristics are variables when performing calculations, necessitating the use of specific nomograms.
Hydraulic calculation of the option of a diagram of a two -pipe system
The incorrect estimate of the expected hot water consumption is part of the hydraulic calculation for the two-pipe heating system with lower wiring, which is one of the system’s potential configurations. The latter is directly impacted by the heat load present at the moment of motion. The aforementioned program and the table (henceforth referred to as reference materials) both contain the specified criterion.
As part of completing the aforementioned computation, the hot water consumption level in relation to a specific area is ascertained. Specifically, the one where the water consumption and the pipe’s constant internal diameter fix the station.
Let us explain the example. We have a branch with ten radiators of 1 kW. The hydraulic calculation of the two -pipe heating system with the upper wiring in this case requires the calculation of water consumption, taking into account that the transfer of 10 kW of heat will be carried out.
When calculating, the precise location is the radiator’s detachment from the heat generator, which is determined by the coolant’s initial course. but only if the diameter of every pipe in the section is the same.
In between the first and second radiators is the next section. The transfer is computed for 9 kW and t.P. in this region.
The scheme of the heating system with EC
Here, we calculate the hydraulics of a gravitational heating system with two pipes. Resistance is taken into account for the pipeline’s straight line and reverse branch in the example given.
The hot water consumption is computed using a unique formula provided in the reference materials.
Heat supply of existing distributors
The minimum hot water speed required for the hydraulic calculation of the two-pipe dead end system in the given scenario is (0.2-0.26) m/mm in order to determine the threshold value. Air starts to escape at slower speeds.
High chance of traffic bottlenecks, which can result in a rejection. The hot water’s maximum speed is limited to a value between 0.6 and 1.5 m/s. Hydraulic noise arises when C exceeds the designated indicator. The range of (0.4-0.7) m/s contains the ideal speed values.
System scheme from distributors
The value of pressure loss in the highway at a specific location is known as hydraulic resistance. By adding up the local values and coolant friction losses in the pipeline, the total resistance is determined.
Additionally, reference materials contain a special formula to calculate the specified indicator.
