10 best heat transfer fluids for a heating system

According to user reviews, this is a very good, high-quality concentrated coolant that can be used in its pure form in the Far North or diluted in temperate climates. The manufacturer promises the preservation of properties for up to 20 heating seasons. A big plus is that the composition includes anti-corrosion additives on an organic rather than silicate basis.

The coolant is compatible with all materials used in heating systems, does not damage them, prevents corrosion, does not form foam when overheated. But some users prefer other options, as this one is based on toxic ethylene glycol.

A modern water-glycol based coolant is designed for pouring into autonomous heating systems. It is completely ready for use - it does not need to be further diluted, the concentration is optimal for the climatic conditions of the middle lane. The complex of inorganic silicate additives gives the substance anti-corrosion, antibacterial, anti-foaming properties.

The crystallization process begins at a temperature of minus 30 degrees, when freezing, there is no increase in volume, which eliminates the possibility of pipe rupture. Minus - antifreeze is made on the basis of ethylene glycol, a toxic substance. Therefore, before filling, it is necessary to carefully check the system for leaks in order to avoid the possibility of poisoning.

One of the best options for filling autonomous closed heating systems of private houses.The coolant is safe for humans and the environment, since it is made on the basis of glycerin. The complex of anti-corrosion additives protects the heating system; when freezing, the substance does not increase in volume, therefore, even when heating is turned off in winter, pipes and radiators remain intact.

A fluorescent dye added to its composition allows you to quickly detect even a slight leak of the coolant. It is also completely safe and contains no toxic ingredients. The coolant can retain the properties of up to eight heating seasons.

Even if trouble occurs and the heating stops working, all pipes and radiators will remain safe and sound. Freezing, the coolant does not increase in volume, it takes the form of a gelatinous mass. This is one of the most reliable, but at the same time inexpensive means for filling heating systems. It ensures the ideal condition of equipment, pipes, preventing the development of corrosion and protecting them from unexpected troubles.

In the reviews, users highlight other advantages of the coolant. This is the addition of a fluorescent dye to its composition, which allows you to instantly detect a leak, no need to flush the heating system after using other antifreezes (oil, alcohol). Minus - the toxicity of ethylene glycol.

The Aquatrust coolant is an order of magnitude more expensive than other means for the heating system, but, according to the manufacturer, it has improved characteristics.This is the latest anti-corrosion formula, three times longer service life compared to standard heat transfer fluids. It is made on the basis of propylene glycol, does not have an aggressive effect on metal, rubber, sealing materials, plastic.

By the combination of characteristics and safety, this coolant can be considered one of the best options for use in residential buildings, catering establishments. In addition to modern anti-corrosion additives, it contains antibacterial additives. The only downside is the high cost.

The modern technological coolant of the Italian brand Pipal, made on the basis of ethylene glycol, has a wide range of applications. It can be used in heating systems of residential buildings and industrial buildings, in the heat supply of passenger cars, as well as in refrigeration and air conditioning. It is produced in the form of a concentrate, which is diluted with distilled or simply softened water.

A balanced set of additives ensures long-term preservation of the properties of the coolant and protection of the elements of the heating system from corrosion, plaque and scale formation. The substance meets all quality and safety standards, for which it receives positive feedback from many users.

A safe coolant based on glycerin does not harm humans and the environment. It is equipped with various anti-corrosion and anti-foam additives that protect heating systems and prolong their service life.It is neutral with respect to any metals, sealing materials, plastic, does not damage them. The freezing temperature of the coolant is -20 degrees.

Compared to analogues, Warme ECO 30 costs a little less, but at the same time it has excellent quality. It can be used in any equipment except for electrolysis boilers. Another feature of the substance is the content of a phosphor dye in it, which makes it possible to immediately detect a leak in the heating system.

Concentrated coolant in residential heating systems is usually used in a diluted form. For heating elements and double-circuit boilers, dilution is mandatory. It is made from high-quality Russian-made ethylene glycol with a complex of various functional additives that prevent the formation of scale, corrosion, and foaming. The product is available in cans of 10.20 and 50 kg.

Heat carriers manufactured by Teply Dom are popular with customers. In the reviews, they confirm the manufacturer's statement that their continuous service life is 5 years. After that, the coolant remains just a non-freezing liquid, and the additives lose their properties.

DIXIS coolant is equally successfully used in heating systems of industrial buildings and private houses. Its main advantage is a very low freezing point down to -65 degrees. According to this indicator, he can be considered one of the best.If the heating system is operated in regions with a relatively warm climate, the coolant can be diluted to the desired concentration with plain tap water.

It is compatible with electric and gas wall-mounted boilers, prevents the formation of corrosion and scale, does not damage metal, sealing materials, plastic and metal-plastic. Complied with one of the main requirements for such means - fire safety.

The heat carrier for heating systems of private houses of the Russian manufacturer TermoTactic is made on the basis of glycerin with a complex of functional additives. It is designed for temperatures up to - 30 ° C, produced on the basis of high-quality European raw materials. This coolant can be safely recommended for use in residential buildings, as it is environmentally friendly and safe, does not harm humans and the environment.

Knowledgeable users also mention other advantages in the reviews - explosion safety, the possibility of mixing with distilled water in any proportions. The functional additive "corrosion inhibitor" eliminates the reaction of the composition with metal, plastic, rubber and other materials.
