The most common today in most countries, including Russia, are heating systems filled with liquid heat carrier. This is a complex of equipment - complex or simple. In the latter case, we are talking about an open scheme. As part of such systems:
- boiler rooms;
- heat exchangers;
- pump equipment stations.
All nodes are interconnected by a pipeline. The quality and characteristics of the circulating fluid will affect the operation of the equipment, so it is so important to choose the right coolant, which will be discussed in the article.
What should be the coolant
If you are faced with the question of how to fill the heating system in a private house, then you must figure out what the coolant should be. The ideal fluid for this role has not yet been invented. This indicates that each of the known materials is operated under certain conditions.conditions.
An important factor is the temperature of the coolant, in violation of which the substance can change its properties, which leads to the shutdown of the system. The correct coolant should carry more heat in a short time, it should have a low viscosity, it should not cause corrosion and should not pose a danger to the inhabitants of the house. Among other things, when transferring heat, heat loss should be minimal, and low viscosity will be an indicator of pumping speed and increase in efficiency.
If you are thinking about the question of how to fill the heating system in a private house, you should know that this or that coolant can cause corrosion, as a result of which you will face restrictions when choosing mechanisms and parts of the system.
User safety
If we are talking about safety, then the coolant should not exceed the standards for toxicity, ignition temperature, the same requirements are also imposed on liquid vapor. An important factor when choosing is the cost. The price should be relatively low, otherwise the consumer should be able to use the coolant for a long time without replacing it.
Water use
Before you decide how to fill the heating system in a private house, you should consider the most common solutionsthis issue. One of them is water, the advantages of which are expressed in the highest heat capacity among all liquids, as well as a lower density. Thus, a kilogram of water, the temperature of which is 90 ° C, will cool down to 70 ° C, while releasing heat in the amount of 20 kcal.
When deciding what to pour into the heating system of a private house with an electric boiler, you can consider as an option water, which differs in environmental and toxicological properties from synthetic substances. It is safe for humans, and if a leak occurs, it will not cause additional trouble. Such a coolant can be easily obtained, with a lack of volume, fill the system with the right amount. This coolant has no competitors in terms of price, you simply cannot find a cheaper liquid.
For reference
If you are faced with the task of how to fill the heating system in a private house, you should consider that water in its usual form should not be used, because it is rich in s alts and oxygen. Over time, from such additives, scale will settle on the internal surfaces of the heating system and corrosion will appear. And in order for the system to work without interruption, the liquid must be softened before use.
To do this, you can use one of the existing methods. It can be thermal or chemical technology. In the first case, the technique is based on boiling. Water must be placed in a metal tank in which it must be heated. When boiling, carbon dioxide will be removed, and s alts will be deposited at the bottom of the vessel. Persistent compounds of magnesium and calcium will still remain in the water. The chemical method acts at the expense of reagents. With the help of soda ash, sodium orthophosphate and slaked lime, the s alts become insoluble and precipitate, becoming a precipitate. Subsequent filtration will eliminate the remnants of harmful substances.
Why many refuse water
If you are faced with the question of what to fill in the heating system of a private house for the winter, then most likely you will have to give up water. In this case, such a parameter of the coolant as the temperature regime plays an important role. If the temperature in the building drops below 0 °C, the liquid will freeze, and this will cause the heating system to break down.
Using antifreeze
When the cold comes, the so-called non-freeze becomes relevant, which is a special liquid for heating systems. If the pipes are filled with such a coolant, then even when the temperature drops to a critical one, they will not burst, which is very important for housing that is used irregularly. In this case, antifreeze is used as an energy carrier, which is designed to operate over a wide temperature range, ranging from -30 to -65 ° С.
When the question arises of what to fill in the heating system of a private housein winter, it is worth paying attention to this option, which does not harden, but acquires an altered state of the gel type when the temperature drops below 0 ° С.
Returning to its original state, the antifreeze will not lose its original properties and will not pose a threat to the heating circuit. To remove foci of corrosion or scale, manufacturers use additives in the form of special inhibitors. Thanks to this, the period of operation of the heating system can be extended by several years.
Things to consider before choosing an antifreeze
If you still cannot decide what to fill in the heating system of a private house - water or antifreeze, then you should take into account the moment that the last of the listed options is designed for only a few seasons of operation. It can be 5 years, or rather, 10 seasons. After this period, the coolant volume must be replaced. Manufacturers generally recommend using antifreeze for about 3 years.
Which coolant is suitable for aluminum radiators
Ethyl alcohol based coolant can be used for the aluminum radiator system, which can be easily prepared by yourself. In the end, it will be possible to obtain a liquid that will be a non-freezing mixture, which includes ethyl alcohol and distilled water. This liquid will have a slightly higher viscosity than normal water. However, this figure will be lower than that of the factoryantifreeze.
The fluidity of this liquid is less compared to antifreeze, which makes it possible to neglect the requirements for the tightness of the circuit connections. Such a liquid will not be able to damage the rubber seals of the system. When consumers think about the question of what to fill in the heating system of a private house with aluminum radiators, they try to choose just such mixtures, since they have one important advantage over other options, which is the ability to use compositions for metal radiators. This is due to the fact that alcohol will prevent the development of corrosion, and this is important for those systems whose destruction can cause unpleasant consequences. In this case, it is recommended to use hard water, which, together with alcohol, will prevent the formation of scale on the internal surfaces of the products. The precipitate will form in solid form and can be easily disposed of with a preventive wash.
Conclusion
Before choosing an antifreeze, it is recommended to pay attention to the fact that these compounds can have different purposes. Some are intended for cars, others for heating systems. They differ in composition, so they cannot be mixed. The raw material can be ethylene glycol or propylene glycol. Quite often, home craftsmen today decide what to pour into the heating system of a private house. Antifreeze, which is also called antifreeze, may differ in viscosity, freezing point and price category. Keep this in mind.
