"Non-frost" for heating: reviews, price. "Non-frost" for heating systems

It happens that the use of water as a coolant is not possible. In such situations, the proceeds come from "frost-freezing" for heating. This fluid has some requirements for operating conditions. It has characteristics different from water, which must also be taken into account when designing a heating system.

Appointment

It's not a secret that one of the most important components of a private house is the heating system. After all, only with the help of it can you endure severe frosts, from which no one is insured in our country, and in general, this is not a rare phenomenon in the winter. But, despite the consumer's readiness for frost, it is necessary to provide some surprises in advance. And, perhaps, the most dangerous of them can become a frozen heating system - not for nothing that this condition is considered emergency.

For the heating system, the emergency situation does not bode well. It is important to note that this can occur not only in the central boiler room, but also in an individual boiler. For this reason, when designing any system, it is necessary to consider the conditions for providing additional security.

According to experts, the most common problem in a private house is the failure of boilers, and, as a rule, this happens always unexpectedly. To prevent such unexpected surprises, as well as to exclude the failure of the heating system and its subsequent cooling, experts advise using an antifreeze liquid.

Composition

"Non-frost" for heating - this is the same antifreeze or antifreeze. The main property of this coolant is not to turn into ice when the temperature is lowered. This results in a thickening of the cooled composition. Any non-freezing liquid for heating systems is manufactured according to the same principle. It contains the following:

• Substances (additives) responsible for the characteristics of the composition;
• Substances (inhibitors) that prevent corrosion;
• The main active component;
• Alcohol (glycol) base.

Active component

Thus, the "non-frosting" a for heating is an alcohol substance. By itself, glycol is not dangerous, but some additives can harm your health. The active ingredient in the non-freezing liquid can be:

• Glycerol.
• Propylene glycol.
• Ethylene glycol.

Ethylene glycol

Heat transfer agent based on ethylene glycol is strictly forbidden to use in houses with permanent residence of people. Restrictions are caused by the fact that this "non-frost" for heating is very toxic and, if it gets on the skin, it can cause a burn. And getting liquid or gas inside the body can lead to severe consequences, even to death.

Tosol

All known low-quality antifreeze - machine antifreeze, which is sometimes also poured into the heating system - is made on an ethylene basis. However, if there is the slightest possibility of human contact with ethylene glycol, then its use should be abandoned for several reasons:

1. In double-circuit boilers, a mix is added to the hot water circuit.
2. Possible leakage.
3. Evaporation from an expansion tank of an open type is possible.

Do not use ethylene glycol non-freezing liquids for systems where a dual-circuit boiler is used as a heater.

Propylene glycol

The heat transfer medium based on propylene glycol is completely non-toxic. Of course, this does not mean that it can be drunk, but if you accidentally hit the skin in minimal doses or even inside, there will be no health problems.

Glycerol

Glycerin "non-frosting" for heating (the price is lower) has been flooded since the middle of the twentieth century and has been successfully used up to the present. Glycerin is a universal remedy, and unlike the previous two, it does not dry the rubber, but instead restores it. In other words, glycerin fluid acts on rubber as a restoring lubricant, as a result, one does not have to worry about the condition of the sealing gums.

Manufacturers overview

Among the Russian consumers, the most popular is the "non-frost" for heating houses of such brands as:

• "Hot Blood Eko."
• Stugna-N
• "Warm house".

When choosing antifreeze, it is important to remember that the content of propylene glycol in it indicates that the process of crystallization of the liquid occurs at a temperature of -60 ° C.

Tips and feedback from specialists

Of course, the liquid - "non-frosting" for heating has different properties, characteristics and feedback on the application, but the main condition is the lack of propensity to freeze. The composition of the antifreeze is determined by the temperature regime at which crystallization occurs. Naturally, you should choose a lower temperature, which is typical for your climatic zone.

The type of heating system determines what "non-frost" in the house heating system will be the most optimal. As already mentioned above, all antifreezes are created using various substances. The composition can contain ethylene glycol, this is a poisonous substance, so it can only be used in closed-type heating systems. The non-freezing liquid based on propylene glycol, according to experts, is less toxic.

Antifreezes contribute to the extension of the operating life of the entire heating system, including radiators. And most importantly, such a coolant prevents the formation of gas formation.

Non-freezing liquid is a mixture of propylene glycol with the addition of various inhibitory components. On average, the life of the antifreeze is 4-5 years.

Conclusion

Quality "non-frost" for heating systems should ensure the smooth operation of the system, even in emergency situations. Therefore, to save on the purchase of antifreeze is completely impractical. You can save only on diluting it with distilled water, but only in this case, if you do not panier to operate the heating system under extreme conditions, for example, in the northern regions of the country.
