A country house, cottage or cottage will become warm and cozy when they have a normal, full-fledged heating system. Due to the fact that equipment for water heating is widely represented on the market today, there is no difficulty in installing and organizing an autonomous heating system for your own home! There remains an important question that owners of suburban housing often face, how to increase the durability of a working water boiler, pipelines and radiators! What happens if antifreeze is poured into the heating system of a house?
The topic of antifreeze when it comes to the efficiency of a hot water heating system?
Traditionally, it is considered that it is better to fill a water heating complex with water, which is the most common and affordable coolant. It takes into account the fact that water can be found everywhere and always. Water has ideal physical properties, among which heat capacity, heat transfer and viscosity are the main ones. Despite the apparent advantages, water has a significant and significant drawback — it freezes at low temperatures. During the heating season, this is fraught with big troubles. If you do not adhere to the operating conditions of the water boiler and the entire heating system in the winter, freezing of the coolant threatens with catastrophic consequences. For our climate, severe frosts are not uncommon, as a result, frozen water in the heating system of the house breaks pipelines and disables radiators.
It should be remembered: The presence of water as a heat carrier in the heating system of a country house requires a constantly operating boiler to maintain a positive temperature in the system. Heating must be constant, even in the absence of household needs, which leads to significant fuel overruns and financial costs.
A comfortable country house, equipped with a water heating complex, needs constant supervision. An unexpected failure of the boiler automation, power outages will cause a complete defrosting of the entire system. The consequences can be the saddest. Not only will we have to change most of the pipes and radiators, but in some cases also eliminate the consequences of the flood.
A warm house after such an emergency is ready to turn into a cold and frozen room, unsuitable for living. Antifreeze for home heating will help solve the problem, a substance that successfully resists low temperatures and does not lose its basic physical properties. How to pour antifreeze into the system, in what proportion to add it to water or use a concentrate, can be found on the websites of numerous companies involved in equipment and installation of autonomous heating.
The heating system in this case will remain functional throughout the entire period of operation, ensuring that your warm home will be reliably protected from frost. Properly selected coolant will provide high performance and technological characteristics of the water boiler. In each individual case, it is necessary to choose a specific brand of antifreeze, which includes the necessary components and additives that ensure reliable heating operation. Switching to non-freezing liquid in the heating system as a coolant is the right step and quite justified.
If you decide to increase the protection of your autonomous heating system with antifreeze, you need to carefully and balancedly approach this issue.
Antifreeze as a coolant. Main properties and characteristics
For water heating in a private house, the main aspect is the compliance of the coolant with the basic requirements. The substance poured into the system must:
- fully ensure efficient heat transfer;
- for a long time not to lose their basic physical and chemical properties;
- not form scale and other by-products of operation as a result of heating;
- withstand low temperatures, preventing freezing.
Evaluating water as a coolant, judging by the characteristics described above, the conclusion suggests itself — ordinary water is not very suitable for these purposes. A warm house with such a coolant becomes unreliable. Despite the fact that water has a high heat capacity and good fluidity, water has a high corrosive effect and quickly loses its basic physical properties under the influence of low temperature. For heating, the quality and composition of water is of great importance. A large percentage of calcium and magnesium content in water causes scale formation as a result of prolonged heating to temperatures above 800C. If the water quality is poor, the water boiler, the pipes in the system are covered with scale from the inside, which significantly affects the quality of heating. Antifreeze for the heating system of a country house in this case compares favorably with water, significantly increasing the operational capabilities of an autonomous heating system.
Antifreeze is known to most of us thanks to its use in automotive technology. The name already says that the main quality of this substance is the absence of a reaction to the effects of low temperatures. The freezing point of this liquid can reach ‑650C. Only when the temperature drops below ‑700With comes the process of crystallization of the substance. The reason for this behavior of the liquid is the high concentration of active components in the substance itself.

Due to its properties and good interaction with water, antifreeze can be added to the water heating system, thereby adjusting the freezing temperature of the entire coolant. The non-freezing composition added to the water in a ratio of 50/50 provides it with the necessary fluidity even at a temperature of ‑400C. The boiler and the piping system in this case are reliably and well protected from freezing during a rapid decrease in the temperature of the atmospheric air. The higher the percentage of antifreeze in water, the lower the freezing point of the coolant and, accordingly, the higher the boiling point.
Today, antifreeze of various brands is quite widely represented on the market. The main qualities and characteristics depend on the type of additives used in the fluid. Each additive endows the substance with certain properties, allows it to better perform the tasks assigned to it. For example, to improve the efficiency of autonomous heating, additives are often used that provide:
- protection of metal components from corrosion;
- dissolution and removal of by-products of heating the coolant;
- protection of various kinds of synthetic gaskets and seals from premature destruction.
Water heating in a house based on antifreeze is an effective tool to ensure the safety of heating during the cold period, to increase the life of the main elements of the heating system. A heating complex filled with a coolant with the addition of antifreeze will make a warm house reliable and comfortable.
Important! Having given preference to antifreeze as a coolant for home heating, it is necessary to use a substance that meets the technological requirements of a water boiler and other parameters of the main elements of the heating system.
How to choose antifreeze for your home heating system
Currently, domestic industry and foreign manufacturers produce various types of antifreeze. The main difference in each brand is the base component. For heating, the best option is antifreeze, which is based on a saline solution, an alcohol base. There are more expensive brands that use propylene glycol or ethylene glycol. When choosing the most acceptable brand, it is important to pay attention to the additive that is part of the liquid. It is necessary to choose a liquid, taking into account the parameters of the water boiler, in the user instructions of which the manufacturer usually indicates the existing restrictions and requirements for the brand of antifreeze.
This type of antifreeze is available as a concentrate or as a ready-to-use solution. As a rule, these antifreezes are called household.
At the household level, propylene glycol-based antifreezes are successfully used. According to its physical properties, this substance has the characteristics necessary for an ideal coolant. The only drawback is the relative high cost of this brand of antifreeze. The priority advantage of propylene glycol antifreeze is the environmental safety of the main components and harmlessness to the human body.
A cheaper option would be to use ethylene glycol-based antifreeze. The substance does not freeze at ‑600C. These grades meet all the necessary technical requirements for coolants, including fluidity and good heat transfer. Nevertheless, heating a country house with antifreeze on ethylene glycol has lost its relevance today due to the toxicity of ethylene glycol. The low cost and rather high technological characteristics of the substance, in comparison with the threat to health safety, are no longer a priority. Which antifreeze to give preference to, you choose. In any case, the choice is associated with the need to compare a number of technical parameters.
There are also antifreezes on sale based on a solution of bischofite and glycerin, which have an absolutely neutral state with respect to the external environment and are not aggressive.
Having familiarized yourself with the advantages of antifreeze for an autonomous heating system, you should not rush headlong into the store and make a premature purchase. With all the apparent advantages of using antifreeze, there are a number of negative points that must be considered.
Before pouring antifreeze into the heating system, you must remember! You should never pour pure antifreeze into the heating system, which only contains propylene glycol dissolved in water. The absence of additives in the liquid will create additional difficulties for you in the future.
Neglect of safety measures and technical instructions will lead to the fact that the piping system at the joints may leak. Rubber exposed to pure propylene glycol tends to warp. Additives prevent the occurrence of chemical processes, the result of which is damage to the connecting seals. With the help of additives, you can also avoid the rapid formation of scale and foam in the system.
Competent and rational use of antifreezes in the operation of autonomous heating systems will allow you to forget about defrosting batteries forever. With the use of additives, as part of antifreeze, you will significantly increase the life of the water boiler and all other components of the heating system of a private house.
