How is the heating system flushed?

In order for any heating system to function properly, it periodically needs to arrange a preventive examination and cleaning. This is especially true for individual heating systems, in which the conditions for using the equipment are rather stringent. Washing of the heating system is needed especially if the quality of the coolant is poor quality hard water. All admixtures, as well as calcareous deposits settle on both the internal parts of the boilers and on the pipes.

Such impurities can significantly reduce the heat transfer of equipment. Flushing the heating system helps prevent the contamination of heating equipment, and also contributes to the continued use of heat exchangers and pipes.

In general, the procedure is carried out using a circulation pump and a tank with a special washing liquid. The pump and the tank are connected to the heating system, the cleaning liquid enters it. Washing of the heating system is carried out until all the impurities are washed from it. Perhaps, the procedure will have to be carried out more than once. Further, the washing liquid is drained and the system is rinsed with hot water. Then the water is drained and a solution is injected, which covers the internal walls of the elements of the system with an anticorrosive layer. After the pipes are rinsed, the heat exchangers are flushed.

In the water used to flush the system, you can add chlorine, which disinfects all internal surfaces. An acid solution is used as washing liquid. After it, the system needs to run a liquid that neutralizes acid residues.

Ideally, the heating system should be flushed every 3-4 years. The presented method flushes out all contours of the system. After this, you need to try to fill the system with better water. Before each heating season, a by-pass flushing of the system takes place, in which water is not needed to drain.

Almost any heating system, even air heating, requires such a cleaning. Air heating systems are constructions from heat generators, for the operation of which liquid fuel or gas is used. In such a system, not water but air is heated. Most often, this design is used to heat large rooms: gyms, industrial facilities, warehouses, service stations and other premises.

The main advantage of this system is its economy, since its performance is very high, and the heated air enters directly into the room. The thermostat can be adjusted in it, so it is easy to maintain the required temperature indoors. Absence of an additional coolant, small thermal inertia makes such heating popular.

But here, too, periodic cleaning of the burner, air ducts and filters is necessary. The combustion chamber of the air heater must also be periodically cleaned of soot or other deposits. Cleaning such a system is quicker and easier, since washing pipes and radiators is not necessary (they simply do not).
