Single-pipe heating system for residential buildings

Heating systems of apartment houses are improving more and more. The development of new, but at the same time simple in use, heating devices is being carried out. The most common are the two-pipe and single-tube equipment designs. The single-pipe heating system has several advantages over the two-pipe system, namely:

• The greatest stability of the hydraulic system;
• Reduction of pipe footage, hence - the mass of the material used;
• The ability to unify parts and nodes for typical and high-rise buildings.

One-pipe heating system is advantageous for the cost of production due to the reduction in the length of the material. In addition, the preferred factor for this heating option is the possibility of producing separate units of the same size. This significantly reduces the cost of manufacturing parts and simplifies the production process. Such advantages are relevant for high-rise and standard houses. In the same apartments are installed the same heating systems.

The single-pipe heating system has hydraulic stability. The amount of coolant passing through the appliances remains unchanged. In connection with this factor, there is no need to carry out commissioning work when the system is put into operation. Single-pipe heating system can be of several types: vertical, horizontal, with bottom and top wiring.

Single-pipe heating system with bottom wiring - vertical

The backbone (feed and reverse) of the vertical system with the lower wiring is located below the level of the placement of the heating devices. The system has the form of risers "U-shaped". Each riser is equipped with an ascending and descending part. In the heating system of this type, the following units are used: flow, with a closing section, flow controlled. Heating systems with one pipe and bottom wiring are used in multi-storey buildings (3-7 floors) without lofts, with a basement space.

Single-pipe heating system with top wiring - vertical

In a single-tube heating system with an upper wiring, the supply mains run above the heating devices, and the return line is located below the heating devices. This scheme has become widespread in multi-storey (9 and more floors) buildings. A heating system with a top wiring in our time implies one-way connection to risers. The connection points of the heating devices can be flowing, with a closing section and flow controlled.

Single-pipe heating system - horizontal

The heating system of the horizontal type has been used in buildings with elongated openings of the luminous flux. The presence of openings requires the installation of devices in the form of rows located under the windows in order to eliminate cold descending flows, as well as to create a comfortable atmosphere in the room. The nodes for connecting heating devices in a single-tube horizontal system can be controlled with closing bypass sections and flow-through unregulated ones. The advantage of this configuration is the possibility of its use for periodic heating of individual building floors.

In modern residential buildings in our time, mainly two-pipe heating design is used. However, single-tube heating is not inferior to it as much as possible to create comfortable conditions. As a rule, in cottages use a heating system of horizontal type with the integration of several devices into one "chain". Which option to install the system for a particular apartment building depends on the economic indicators and the type of project.
