Antifreeze for heating system: price, reviews

As a working fluid in heating systems, water has become the most widespread, due to its availability and low cost, as well as special physicochemical properties. However, its use as a working fluid has a number of notable shortcomings, in connection with this recently a new type of coolant, called "antifreeze for heating system."

Advantages of non-freezing liquid

• First of all, you need to pay attention to the problems that can arise when using water in the heating system. The main disadvantage of this coolant is this - if in winter time do not turn on the heating system on time, then there may be a freezing of water and, as a consequence, a rupture of pipelines, which threatens with expensive repairs. The given problem is especially actual for premises in which residing has a seasonal character.
• Using water in the heating system as a working fluid over time can lead to the formation of piping, radiators and a scale boiler, which worsens the heat exchange processes, after which the efficiency of the system can be reduced by 30%.
• With a decrease in efficiency, fuel consumption increases , which significantly increases the cost of heating.
• The coolant antifreeze for the heating system fits much better, as it has no such drawbacks, because it contains various additives that allow to 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 concentrate contains only the main component - propylene glycol or ethylene glycol. For our climate, the standard proportion of dilution of concentrates is: two volume parts of water are taken one volume part of the concentrate.

• The ready-to-use non-freezing liquid contains water and is a 45% solution of the concentrated base material. This antifreeze for the house heating system is designed for use at temperatures up to -30 ° C.
• Before filling the heating system with antifreeze liquid, concentrate is preferably diluted with standing, filtered or distilled water.
• The safe concentration in the water of ethylene glycol is considered to be up to 1 g / l. In this concentration, he is not capable of harming the environment.
• Also it is necessary to pay attention to the aspect that antifreeze for the heating system, in comparison with water, is characterized by a lower coefficient of the surface tension. This leads to the fact that the antifreeze liquid penetrates more easily into cracks and pores, and also has a greater fluidity.
• Rubber in the medium of ethylene glycol swells more slowly. Therefore, in case of replacing old water with antifreeze water, leaks may appear.

Manufacturers overview and prices

Consider as an example some modern antifreezes for heating systems, which are based on various chemicals.

• DIXIS-65.
• "Defries".
• "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 are anti-corrosion, heat-stabilizing and anti-foaming.

For this brand, the crystallization temperature is -68 ° C, which allows it to be diluted with simple water.

Non-freezing liquid of this brand is supplied in containers from 10 to 50 liters, also on sale you can find barrels of 200 liters. Retail price of this mixture for 1 liter will be from 70 to 90 rubles.

"Defries"

At the heart of the non-freezing liquid "Defries" is the bischofite substance. Also included in its composition is an additive package, which reliably protects the pipelines from the appearance of scale.

This mixture is realized in capacities of 10 and 50 liters. The cost of antifreeze for 1 liter on average is 55-100 rubles.

"Hot Blood-65 Eco"

This antifreeze is a non-freezing liquid for heating systems based on propylene glycol. The concentration of propylene glycol is a kind of guarantee that the crystallization temperature does not exceed -65 ° C, which in practice makes it possible to dilute it with simple water in half.

It is a fireproof and non-toxic antifreeze for the heating system. The price of it for 1 liter will be 75-90 rubles. It is sold in packs of 10, 20 or 50 liters, it is also possible to pack into the container of the buyer.

Stugna-N

This variant of the non-freezing liquid is made on the basis of glycerin and is considered environmentally safe. The freezing point of this mixture is about -17 ° C.

A special additive package reliably 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. The price of it for 1 liter ranges from 70 to 150 rubles.

Expert Reviews

So, the antifreeze for the heating system of the reviews of specialists has the following:

• This coolant is perfectly suitable for unpredictable everyday life in our country. If you pour it into the heating system, then in your absence you can be sure of its safety.
• Purchase non-freezing liquid only in specialized stores to prevent the possibility of buying a defective product or counterfeit.
• In order to establish the ideal heating with the use of this coolant, it is enough just to choose a powerful pumping equipment and radiators.
• Non-freezing liquid is safe for human health and life, it can be used not only in private households, but also in medical and educational institutions.
• With proper use of this type of coolant, it can serve you for at least five years.
• Non-freezing liquid for the heating system makes sense to use only in those cases when there really is a possibility that water inside the network can freeze.
