Choice for every taste and budget: diagrams of the most efficient connection of heating radiators
Heating systems are used to maintain heat in buildings. Most include radiators, which are mounted in several ways. The options depend on the structure of the harness and the batteries used.
At first glance, there are few differences in the schemes, but It's better to leave the choice to a professional. A specialist will help to draw up a competent project that will not only take into account the owner’s wishes, but will also work efficiently.
How to connect radiators to a one-pipe heating system
It is widely distributed due to cheapness and ease of installation. In most apartment buildings, the piping is done in this way. In private buildings, it is less common. Radiators include in the wiring in series. The coolant makes a circle from the boiler, visiting each battery in turn. From the extreme section of the circuit, the liquid returns to the return inlet.
Such a system has a couple of disadvantages:
- It is impossible to adjust individual radiators. Installation of a controller is possible, but only the complete chain can be controlled.
- Serial connection leads to deterioration of heating in distant areas piping, since the working fluid loses heat along the way.
The Best and Worst of a Two-Pipe System
Unlike his partner, has a forward and a return pipe, the purpose of which, respectively: to supply hot water, return cooled water. Each battery of the system connected in parallel. This increases heating of distant areas chains. Two pipes allow you to install regulators in front of each radiator, with the help of which the required temperature is set.
The disadvantage is complexity of installation and increased costs.
Reference. Price increases almost twofold, compared to a one-pipe heating system.
What is the most efficient battery connection diagram?
Distinguish three ways radiator installations.
Diagonal
It is considered the most effective and is used in most cases.
Photo 1. Four options for diagonal connection of a radiator to the heating system, for one-pipe and two-pipe systems.
This associated with high efficiency:
- The coolant enters the battery from the upper corner.
- The liquid is distributed throughout the entire available volume.
- It flows out at the opposite point.
This is the scheme used testing systems in factories.
Lower
It is less common than others because it has lower efficiency. Both pipes are connected to the bottom of the battery. Middle losses amount to 15%.
Photo 2. One-pipe and two-pipe method of lower connection of the heating battery. In the second case, more materials are needed.
On the plus side It is necessary to highlight the possibility of installation in the floor, which hides the piping. And to compensate for the low efficiency, it is recommended to install a more powerful radiator.
Should not be used a similar scheme in a harness without a pump, since a vortex phenomenon occurs. The flow heats the surface of the pipes, increasing heat transfer during natural water circulation. The phenomenon has not yet been studied, so the possible consequences are unclear.
Lateral or one-sided
True to its name, the pipes They are included from one side: at the upper and lower corners. A similar installation option is used in buildings with vertical mains, for example, in apartment buildings. This diagram not used when connecting the coolant from below, since installation becomes much more complicated.
Photo 3. Both single-pipe and two-pipe systems allow for lateral connection of the battery. In the first case, a bypass is required.
Possesses high efficiency, slightly smaller than the diagonal scheme. This applies to radiators with 10 or less sections. Long batteries warm up worse, since the working fluid has to travel a long way in one direction.
Important! This factor does not affect panel heat exchangers, into which special rods are placed to improve feed.

How to make the best choice
In private houses It is recommended to use two-pipe piping, although it is more expensive and more difficult to install. Among the radiator connection schemes, you need to choose according to the desired result. The best warm-up provides diagonal, A from an aesthetic point of view is in the lead lower.
