The heating medium for the heating system of a country house: the nuances of selection

In the current environment of reasonable alternatives to liquid heat transfer media does not exist. They are used in household and industrial objects with different types of radiators and heating equipment. To select the best coolant for country house heating systems You need to learn more all the options.

What is a heat transfer fluid

At first it is necessary to clarify the functions that perform the appropriate fluid in the heating system. Also useful compatibility with existing equipment records. Important factors evaluated in the aggregate:

• First carriers accumulate heat. Hereinafter - are used as the energy transport means is at a relatively short distance. Consequently, the necessary high enough heat capacity per unit volume. This will allow to operate with a smaller amount of liquid while successfully maintaining a comfortable environment indoors.
• Good heat transfer medium for a country house heating system should not exert negative influence of its components. Preference is given to chemically neutral substances.

• In the presence of sealing parts can be damaged by corrosive fluids impurities. Certain compounds of calcium and magnesium by heating to 40 ° C and above to form dense growths. Over time, they are able to clog the major technological channels. Such impurities should be removed.
• The cost of the liquid is also important. It is considered taking into account the estimated useful life before replacement.
• In the residential facilities is better not to use potentially dangerous to people, pets and plants substances. Otherwise it is necessary to take additional measures to ensure reliable sealing contours heating systems.

Separately it is necessary to study the temperature regimes. In the range (heating and cooling) fluid must retain their consumer options in good condition. Unacceptable in a solid and a gaseous state, a change in the chemical composition.

What parameters has quality coolant for a country house heating systems

The above are the general requirements for a suitable liquid. But in reality, you must also consider the features of the future operation. Least of all the problems occur when the year-round use residential facility. In this case, well suited plain water. It is enough to create the conditions that exclude the decrease in temperature pipe to a critical level. This means that the heat will have to be maintained at attic, In the basement, and other technical areas.

If you set electric heaterConnected to centralized networks, have to consider additional measures. In the event of accidents sluggishness repair services can create a dangerous situation. Eliminate possible trouble can be as follows:

• change boiler on models operating with a liquid (solid fuel).
• Install a stand-alone petrol or diesel generator.
• Pour into the freezing water heater country house heating system.

Important! Some manufacturers of heating equipment impose special restrictions on the type of liquid. The use of other carriers degrades performance. In some cases - terminates the formal guarantees.

Features various liquids

Based on the above information should be verified the possibility of using various heat carriers. A comprehensive assessment will help make the right decision.

Water

The following items should be noted in the study of the liquid:

• Clean water is inexpensive. Its reserves are easily replenished. When carrying out repair work, changing the pressure level the system no significant problems and costs will not.

• After heating and subsequent cooling water is able to pass when the temperature decreases to 1.06 - 1.17 W of heat energy per 1 liter volume. For this indicator, it is much superior to the alternative media. They contain additives that reduce the heat capacity.

• Not a contaminated water is absolutely safe. That it is the main component of the human body, present in most life processes. Damage to seals when using it - it's just a little damage, which is eliminated without special precautions.

When using the water coolant temperature in the reduction private home heating system level less than 0 ° C are not permissible. The liquid not only clog the duct. After transformation into ice will expansion agent. Not only plastic, but also rugged metal parts can be damaged. Especially dangerous are hidden inside accident concrete and other building structures. Their elimination is accompanied by a large amount of time and money.

The above-mentioned filling drinking water really should not be used. In such liquids mineral compounds are present, potentially dangerous for the heating systems. Some of them with little heat is converted into solid precipitation.

Water - good solvent, so it accumulates a variety of impurities. It contains oxygen. This gas activates oxidation processes damaging metals.

The transformation to a solid state unchanged determined laws of physics. But some of the other disadvantages of such coolant to eliminate without the high cost.

Note! The last figure shows a set of equipment for preparation of drinking water. Its performance is not high, so the set storage tank added. But it is sufficient for self-heating food. Multilevel not pass filtering particles larger than molecules of water.

Proper use of ethylene glycol

Using antifreeze for heating the price will rise. But in this case they will be excluded risks freezing of fluids in pipes. If you purchase a composition that is based on ethylene glycol, it will maintain the fluidity to -60 ° C. It should be noted that the crystallization starts at extreme levels. Gel-like material can not be used as a coolant. But it will not increase in volume, and after raising the temperature again becomes fully functional.

However, the extreme temperatures rarely observed even in the Far North. In the middle latitudes, they are not below -35 ° C. The concentrate was diluted with distilled water in view of data from this table:

Important! When the concentration of the active substance over 64%, the reverse reaction. Therefore, such actions are not suitable.

Such nezamerzayku for heating their own hands is not difficult to bring to desired consistency. But when it is used it is necessary to pay attention to the nuances of the following:

• Operating fluid term is defined in the manufacturer's instructions. It generally does not exceed 3-5 years.
• The viscosity of such compositions higher than the water. It requires a precise calculation. But in most cases it is necessary to install a more powerful pumping equipment. For systems with circulation under the influence of forces like gravity of the liquid are not appropriate.
• As noted in the preceding paragraphs, the water has better heat accumulation performance. Using antifreeze reduces the efficiency of the heating system.
• When heated, the relative expansion greater than water. It is necessary to make appropriate changes in the equipment.

With increasing temperature ethylene gas formation is activated. They are not output via bleed screw standard plumbing and other devices form the plug. A subsequent increase in temperature provoking expansion of the chemical compound to form a solid precipitate and acid components.

safe propylene

In order not to create unnecessary difficulties, propylene glycol is used. This connection is not able to cause harm. It can be used even in combi boilers.

The cost of such anti-freeze up. They, like ethylene glycol compounds decompose zinc compounds. We must take this into account when the heating system configuration.

Heat transfer fluid based on glycerol: the advantages and disadvantages of proven solutions

If you want to learn how to make anti-freeze in the home, experimenting better with this chemical compound. Glycerin is completely harmless to human body. He does not react with zinc, for a long time keeps the original specifications in an unaltered state. This coolant is inexpensive. But if it should move to increase the pump performance due to the high viscosity of the mixture. At about + 91 ° C compound decomposes with the release of gases, conversion to the jelly state.

Purchase of coolant

To find out the exact amount of fluid necessary to drain it using dimensional containers. The second method - addition volumes of pipes, radiators and other parts of the system. To simplify the calculations, you can use the calculators, which are available free of charge on the websites of specialized vendors.

Output

It is impossible to determine how best to use coolant in the heating system without taking into account the composition of the equipment, particularly its operation. For the correct decision must be analyzed in a complex given the advantages and disadvantages of each option.
