The upper and lower wiring of the heating system

Heating for one and two pipe

upper wiring of the heating system is that the supply line is in the attic or under the ceiling.From the supply pipe risers are laid down with the tubes attached to them, which in turn are connected to the radiators.The return laid on the floor or in the basement.Such a system of polypropylene pipes is the undisputed choice for arrangement of the heating system without circulation pump.

In other heating circuits circulating pump should be present without fail.Furthermore, when the heating system on top of the device with the wiring must be installed in the attic expansion tank, to protect the system from pressure changes and air vent.

Bottom routing characterized in that the straight pipe runs parallel to the return pipe on the floor of the first or ground floor or in the basement to the ceiling.Such a layout using polypropylene heating pipe is used for the organization of the coolant flow in each riser.

Heating is one- and two-pipe, as seen in the number of pipelines extending from the backbone.Installing pipe systems, we are aware that in this scheme there is the alternate connection of the pipe system for each device.Moreover, from one radiator to another, the farther the system, the coolant temperature becomes.This system is used for large houses, where he first connected to heating residential premises, and then subsidiary or business.

pipe system is designed so that the hot exhaust flow and have gone to different pipelines - for forward and reverse.In this case, each radiator coolant will be delivered at the same temperature.The great advantage of two-pipe heating system with radiators connected to the polypropylene pipes is that in case of emergency, you can disable the problematic riser, without depriving the whole house heating.

Bussing heating for horizontal and vertical type

Vertical type of wiring it is usually done in high-rise buildings, where the coolant has to pass through the risers from floor to floor.With this system it is possible to fix a separate riser without disabling others.

horizontal layout - is the main riser and floor branching in the one- and two-pipe versions.This scheme is more modern and used in new apartment blocks, where each apartment is given its own wiring.

is horizontal type and perimeter beam in turn.

Perimeter heating system

This system is connected to the central riser and heat transfer fluid moves sequentially on all radiator batteries located around the perimeter of the apartment or floor.This scheme has its drawbacks:

• when repairing a radiator is necessary to turn off the entire perimeter;
• difficult to drain the coolant, because the wiring is located on the same level horizontally.

advantages of the perimeter of the system is the possibility of hidden highways mounting in the floor.

Collector-ray

heating circuit Similarly to the previous system is connected to the central riser.The main difference of such a scheme - a distributing pipe for individually rooms like the rays of each radiator.Unified system piping is formed in the manifold near the riser.The disadvantages of this system are similar to the perimeter, and dignity - the ability to turn off one heating branch, without depriving others of efficiency.

choosing the optimal heating system, it should take into account the climatic conditions of the place of residence, number of floors premises on heating load devices separately, the possibility of emergency stop.
