Why is water - not the best choice for heating the coolant
Despite the good heat capacity and wide distribution, the water can not be considered the best option for country house heating systems. In its structure there is always dissolved substances that can have a negative impact on the pipeline elements. Salt and impurities as a sludge dropping reduce the transverse dimensions of the circuit and impair heat transfer. As a result of having to spend more energy to maintain the optimum temperature in each room.
For those who are resident in a country house may choose distilled water as coolantAnd from an economic point of view, such a choice would be fully justified. Provided that it is a closed system and there is no risk of freezing coolant.
If the system is not stable, the heating is switched off periodically - should buy a different composition. Elements belonging to it will prevent the freezing of the circuit when the temperature drops below zero.

What to fill in a private home heating system: requirements for the coolant?
Living in the house constantly, it is easy to monitor the status of the heating system. Those who in the winter will go and see the suburban housing only from time to time, it may be difficult to decide what to fill in private home heating systemTo prevent freezing of the circuit during the winter.
With this task well handle special coolant - antifreeze, which remains in a liquid state even at a sufficiently low temperature. Such compositions must meet the following requirements:
- safety for human health. In case of accidental contact with the coolant, for example, in the case of a leak, the composition should not harm the health of family members;
- safety for system components;
- efficiency. The composition should have sufficient thermal capacity to rapidly heat the indoor air;
- Long service life.
Despite the fact that these criteria fully meets the distilled water, often due to its freezing at temperatures below freezing most opts for anti-freeze. Such materials may have different compositions, which determines their possible area of use.

The main types of antifreeze for heating systems and their specifications
Antifreeze is often made on the basis of ethylene glycol and propylene glycol, which in its pure form is a rather aggressive environment. Introduction of special additives to prevent occurrence of foam and to protect the elements country house heating systems. Please find the main types.
Heat carrier "Propylene Glycol" for heating system
As a rule, on the package of anti-freeze can be seen the inscription "ECO". This is due to the absence in the composition of elements harmful to human health. It can be used for dual and single-loop systems. It has a characteristic green color. It has a high frost resistance. Depending on the composition, it is able to remain liquid at temperatures down to -35C or until -65S.
Manufacturers offer a "propylene glycol" coolant for the heating system in an already finished product. Its cost depends on the amount of additional additives. The introduction of some substances contributes to the durability of the heating circuit elements for a substantial period.
Ethylene for heating
The most common type through an affordable cost. Of red color. Implemented in a concentrated form solution ready for use and having a lower boundary crystallization -30 ° C. The concentrated composition is diluted with distilled water in a ratio that depends on the location of a country house. The final solution should remain in a liquid state at a minimum temperature for a specific region.
Ethylene glycol heating systems is not the best choice. To improve the performance of antifreeze, special additives are added to its composition. They help reduce foaming appearing at high temperature and protect metal parts from corrosion heating circuit.
Attention! Ethylene glycol is able to have a negative impact on the zinc coating, and therefore use the coolant in the system of a country house heating having similar elements, it is prohibited.
triethylene glycol
Rarely used type of antifreeze. Used in heating systems with a high operating temperature of up to + 180 ° C, and having a high level of thermal stability. It relates to compositions for special purposes. Depending on the percentage of the basic substance density of the solution may be 1.121 - 1.124 g / cc.
Attention! Opting for the TEG must be made at the stage of designing the heating system.
The advantages and disadvantages of a given antifreeze
Proposed compositions manufacturers have their own advantages and disadvantages. To discover the characteristics of each composition, before to give preference to certain.
The advantages of propylene glycol should include environmental safety. Suitable for dual systems. A small amount of hot water is not able to have a negative impact on human health.
Antifreeze has a large heat capacity, and therefore allows more efficient heat the whole room in a country house. Due to the lubricating effect it is possible to reduce the overall flow resistance. The result is increased efficiency of the heating system and reduces energy loss, to optimize the cost of a country house maintenance.
The disadvantages of propylene glycol antifreeze is attributed increased costs. Buy propylene Heating can be at a different price depending on the number and characteristics of the additives injected. Moreover, the composition should not be in contact with galvanized elements.
The main advantage of etilenglikolyavlyaetsya its availability. Buy antifreeze for heating systems are at an affordable price. However, such antifrizyavlyaetsya poisonous substance, and therefore to the tightness of the heating system are increased requirements. Even a small amount of the composition in the liquid or vapor phase could have a harmful effect on the human body.
Ethylene glycol is afraid of exposure to high temperature. When heated above the set temperature starts composition irreversibly degradation process. The solid formed insoluble precipitate can become a cause of clogging pipes. The liquid phase formed aggressive acids that can cause corrosion of metal surfaces fracture. Despite the presence of modifying additives, antifreeze begins effervescence that adversely affects the health of a country house heating systems.
Choosing antifreeze to the heating system of a country house: the ground rules
Availability of various compositions creates certain difficulties. Focusing on certain rules, it will be possible to pick up, fully meeting the requirements of the heating system.
What is the best anti-freeze to heat your home: Make your choice
Proposed compositions manufacturers will not allow the system to freeze in winter. However, due to the large range it can be difficult to decide what kind of antifreeze for heating the house better. Before you give preference to a particular mind, it is necessary to ensure that the use of such a composition is possible in principle. From "nezamerzayki" should be discarded if:
- an open system;
- Natural circulation loop;
- It has elements with a galvanized surface, which will be in direct contact with the coolant;
- seals are used, consisting of tow with oil paint;
- Boiler equipment can not maintain the temperature within a certain range.
If you decide to give preference nezamerzayku for heating private houses, should be the choice of:
- Check availability of additives and clarify their purpose. ethylene glycol solution without modifying elements will corrode inner surface.
- Make sure ekspluatatsiioborudovaniya conditions in a country house as desired.
- Check the expiration date. All formulations in the original packaging for a long time are able to maintain their performance.
- Make sure that the packaging material is allowed to keep operating properties.
- Check availability of quality certificate.
Antifreeze color - red, green, blue - what's the difference?
When selecting the composition of many guided by color. It depends on the chemical composition of the base and modifying additives. What is the difference mezhdukrasnym, green sinimantifrizom? In operating conditions, efficiency and effects on system components. Traditionally, green formulations are safer than red. The latter method is a negative impact on human health and places high demands on the equipment operating conditions.
for heating the liquid "Warm House", its main varieties, advantages and disadvantages
Antifreeze for heating systems "Warm House" should be used, taking into account a number of features that should be considered at the design stage and the choice of equipment. For the selected circuit tubes larger cross-section, and boiler - with more power. From the storage tank should be abandoned.
Liquid "Warm house" for heating may be in contact with all the materials except zinc coatings. In this case, there is a chemical reaction with the formation of white flakes. In other cases it will not be observed as a characteristic of the destructive influence of the metal, and the various polymers. The negative impact may take place only if the life of the composition is over. It should not buy, if used for heating country house electric boiler.
Attention! In case of overheating "Warm House" is losing its performance.
How to fill antifreeze closed heating system
If you want to fill the coolant system, many seek help from professionals. However, knowing how to fill antifreeze closed heating system, all the work can be done in-house. Should be prepared:
- screwdriver;
- pliers;
- adjustable wrench.
In addition to the antifreeze, it should be in the presence of the following materials:
- hoses for supplying coolant;
- clamps for fixing the hose in certain places;
- fum-tow or tape to protect threaded joints.
Filling the heating system in the following order:
- Drained the old coolant.
- Inside pour antifreeze system. Work is carried out with the use of hoses and circulating pump.
- Fixing one end of the hose at the outlet of the pump, and the second on the drain pipe by means of clamps include pump - antifreeze and begins to flow into the system.
- Air is removed from the system.
Attention! Care must be taken when the antifreeze in the canister end. Otherwise, the air gets inside contour.
Which is better to use radiators with antifreeze
Material heating elements is closely related to the composition used coolant. Before you buy antifreeze specific brand image, make sure that its structure allows the filling of batteries made of a certain material. It is important to understand how to choose a heat transfer fluid aluminum radiatorsAnd which is necessary to get to cast iron.
different types battery will react differently to the same anti-freeze:
- aluminum radiator It will be paired with an electrolytic brass stop valves or copper pipes;
- Cast iron radiators antifreeze will be an ideal choice, if, instead of the rubber seals between the sections to put the polymer;
- steel elements suitable for low pressure systems. However, the number of sections have to be increased;
- bimetallic products may contain electrolytic couples, but because of their setting should be abandoned.
