As the working fluid in heating systems, the most widespread, due to its availability and low cost, as well as its special physico-chemical properties, was water. However, its use as a working fluid has a number of noticeable shortcomings, in connection with this, a new type of coolant has recently appeared, called "antifreeze for the heating system."
Advantages of non-freezing fluid
- First of all, you need to pay attention to the problems that may arise when using water in the heating system. The main disadvantage of this coolant is such a moment - if you do not turn on the heating system in time in the winter, then water may freeze and, as a result, rupture of the pipelines, which threatens with expensive repairs. This problem is especially relevant for rooms in which accommodation is seasonal.
- The use of water in the heating system as a working fluid over time can lead to the formation of scale in pipelines, radiators and a boiler, which impairs heat exchange processes, after which the efficiency of the system may decrease by 30%.
- With a decrease in efficiency , fuel consumption increases, which significantly increases heating costs.
- The coolant antifreeze for the heating system is much better, since it does not have such drawbacks, because it contains various additives that can reduce the crystallization temperature to about 15-40 ° C.
Recommendations for use
These substances can be sold both in ready-to-use form and in concentrated form. Antifreeze for the heating system in the form of a concentrate contains only the main component - propylene glycol or ethylene glycol. For our climate, the standard proportion of concentrate dilution will be: one volume part of the concentrate is taken for two volume parts of water.
- Ready-to-use non-freezing fluid contains water and is a 45% solution of a concentrated base substance. Such antifreeze for home heating systems is designed for use at temperatures up to -30 ° C.
- Before filling the heating system with non-freezing liquid, it is preferable to dilute the concentrate with settled, filtered or distilled water.
- A safe concentration of ethylene glycol in water is considered up to 1 g / l. In such a concentration, it is not able to harm the environment.
- You should also pay attention to the aspect that antifreeze for a heating system, in comparison with water, is characterized by a lower coefficient of the tension surface. This leads to the fact that non-freezing fluid penetrates into cracks and pores more easily, and also has a greater fluidity.
- Rubber in ethylene glycol swells more slowly. Therefore, if water is replaced with antifreeze in old networks, leaks may occur.
Overview of manufacturers and prices
Let us consider as an example some modern antifreezes for heating systems, which are based on various chemicals.
- DIXIS -65.
- "Defreeze."
- "Hot Blood-65 Eco."
- "Stugna-N".
DIXIS -65
This antifreeze for the heating system is a solution based on monoethylene glycol. In addition, it includes a wide range of additives, among which it is worth noting anti-corrosion, heat-stabilizing and anti-foaming agents.
This brand is characterized by a crystallization temperature of -68 ° C, which allows it to be diluted with plain water.
Non-freezing fluid of this brand is available in containers from 10 to 50 liters, also on sale you can find barrels of 200 liters. The retail price of this mixture for 1 liter will be from 70 to 90 rubles.
Defreeze
The basis of the Defreeze non-freezing liquid is bischofite. Also, it included a package of additives that reliably protects pipelines from the appearance of scale.
This mixture is realized in containers of 10 and 50 liters. The cost of antifreeze per 1 liter on average is 55-100 rubles.
Hot Blood 65 Eco
This antifreeze is an antifreeze liquid for heating systems, the basis of which is propylene glycol. The concentration of propylene glycol is a kind of guarantee that the crystallization temperature does not exceed -65 ° C, which allows in practice to dilute it with plain water twice.
It is fireproof and non-toxic antifreeze for the heating system. Its price for 1 liter will be 75-90 rubles. It is sold in containers of 10, 20 or 50 liters, and packaging in the buyer’s packaging is also possible.
"Stugna-N"
This version of non-freezing fluid is based on glycerol and is considered environmentally friendly. The freezing temperature of this mixture is approximately -17 ° C.
A special additive package protects the heating system from salt deposits and corrosion. In 50-liter cans or 10-liter containers, you can purchase this antifreeze for the heating system. Its price for 1 liter ranges from 70 to 150 rubles.
Reviews of specialists
So, the antifreeze for the heating system, the reviews of experts has the following:
- This coolant is perfect for the unpredictable everyday life of our country. If you pour it into the heating system, then in your absence you can be sure of its safety.
- Non-freezing liquid should be purchased only in specialized stores to prevent the possibility of buying a low-quality product or a fake.
- In order to establish perfect heating with the use of this coolant, it is enough just to choose powerful pumping equipment and radiators.
- Non-freezing fluid is safe for human health and life, it can be used not only in private households, but also in medical and educational institutions.
- With the correct use of this type of coolant, it will be able to serve you for at least five years.
- It makes sense to use non-freezing fluid for the heating system only in cases where there really is a chance that water inside the network can freeze.
