Recommendations for replacing the coolant and caring for the heating system

In accordance with the regulatory documents of Ukraine, the design and installation of thermal systems must be carried out in accordance with SNiP 2.04.05. And further operation and maintenance, replacement of coolant for heating systems are carried out in accordance with the document networks” No. 71 dated February 14, 2007.

How a heating system is flushed.

Before describing the flushing process itself, it should be said when the heating system is flushed. The above normative document recommends flushing the heating system annually, after the end of the heating season. This is due to the fact that it is after the heating season that deposits and scale on the inner walls of the system become looser. Therefore, they are much easier and faster to remove.

Although these regulations apply to systems that are charged with ordinary water, it is recommended to follow them when filling systems with glycol coolants or replacing the coolant.

We also recommend flushing the heating system and checking the reliability of pipeline connections when replacing water in the heating system at glycol coolant. Because the anti-corrosion additives that are in the coolant can direct their effect on the dissolution of deposits and their inhibition in the system. Which, in turn, will lead to rapid deterioration of the coolant and incorrect operation of the entire system.

Benefits of flushing a heating system:

  • system is cleaned of deposits, scale, corrosion and other sludge
  • pipeline throughput increases
  • improves circulation in the system
  • reduced electricity or gas consumption
  • 30% reduction in thermal system efficiency
  • significantly increases the service life of the system and pumping equipment
  • saving material resources by increasing the heat transfer of the heating system.

1mm of deposits and sludge in the system reduces heat transfer by up to 25%. This can be compared to covering pipelines with thermal insulation material.

Ways to flush the heating system.

There are several technological ways to flush the heating system. These include: chemical or biological washing, hydrodynamic and pneumohydropulse. The choice of flushing technology depends on the modification and material of the heating equipment, as well as the pipeline. Hydrodynamic flushing is not recommended to be done by yourself. in order to avoid gusts and equipment failure, this should be done by specially trained people. You will also need special equipment.

The benefits of chemical (biological) flushing system:

  1. Economy
  2. The ability to do it yourself
  3. No additional hardware required
  4. Does not require dismantling the system
  5. Efficiency and speed of the cleaning process

When choosing a product for chemical flushing of the heating system, you should carefully check its composition and compatibility with the materials of your heating system.

Company Novokhim offers to buy chemical scale remover (anti-rust) based on glyoxal. Anti-rust is non-corrosive and can be recommended for a variety of metals including aluminium, copper and brass.

Anti-rust does not damage system gaskets and seals. In addition, it forms a protective layer on the treated surface, which prevents the re-formation of deposits on the inner walls of the pipeline system. The spent solution, depending on the degree of contamination, can be reused or washed down the drain. Does not require special disposal.

IMPORTANT!!! Carry out flushing of thermal equipment before replacing the coolant or when switching from water to glycol coolant for heating system .
After applying a chemical flush, thoroughly flush the system with water to completely remove chemicals.
Also, do not forget to check the heating system for leaks after installing the system, repairing the pipeline section, replacing the coolant, before and after the heating season.
Regularly maintaining a heating system in excellent working order is much more expedient and economical than spending money on periodic repairs and troubleshooting.

If you have any questions about flushing the heating system, choosing a coolant, for calculating the amount of antifreeze, please contact the Novokhim Company.
