A remedy for the yellowness of bimetallic heating radiators. We wash the heating battery. Tips for all kinds of radiators. Silicone paints for metal

Bimetallic radiators, which, as the name implies, are made from a composition of two metals, began to be produced more than fifty years ago in European countries. They quickly gained wide popularity due to their reliability and operating efficiency when installed in any heating system.

Which bimetallic batteries are better to choose, and what should you pay special attention to? This question always arises for all those who decide to replace the old heating appliances for more modern options, different and high operational characteristics, and respectable appearance.

Today production bimetallic radiators established in Russia. Domestic products are quite popular, and have fully justified themselves when installed in central heating systems.

General design principles

This type of radiators consists of two main parts, made of different metals.

Internal channels are made of of stainless steel, external heat exchanger casing made of aluminum

Their inner part is made of stainless steel or, less commonly, copper, since these metals are highly resistant to the aggressive environment of a heated coolant. Pipes made of these materials are arranged vertically and horizontally, and it is through them that the coolant circulates.

The outer part of the radiators is, in fact, a casing equipped with fins, which is made of. This metal has excellent thermal conductivity and quickly warms up, giving off heat to the premises, which is why it was chosen for the outer part of the structure.

The inner and outer parts of each section of the radiator are joined together by injection molding or spot welding. Sections are assembled into a battery using steel nipples and heat-resistant rubber gaskets, designed for temperatures up to 200 degrees. However, in addition to such batteries, there are also monolithic radiators made of the same materials.

Crimping passport pressure bimetallic batteries at different manufacturers may vary - this indicator depends on the material of manufacture internal pipelines and dimensional parameters. If, during the pressure testing of certain models, a test pressure of 35 atmospheres was created, then they will be able to withstand water hammer, during which pressure drops reach 25 ÷ 30. This allows the use of such radiators in central heating systems, which sometimes do not differ in the stability of the coolant pressure.

Due to the high thermal conductivity, bimetallic devices turned out to be even more efficient than the familiar cast-iron batteries.

On the appearance bimetallic radiators practically do not differ from aluminum models. However, they can be distinguished by weight, because due to the steel pipe "core", bimetallic batteries are heavier than aluminum ones, by about 50%. In order not to make a mistake when choosing, you should definitely study the certificate of conformity and other accompanying technical documentation, which must be attached to the batches of products, and is located at the seller of a specialized store.

Bimetallic and semi-bimetallic radiators

In addition to bimetallic, semi-bimetallic radiators are also produced. You need to know how they differ from each other, and which ones are better.

• Bimetal devices

In real bimetallic radiators, only the outer casing of the device is made of aluminum.

Their production process consists in the fact that ready-made all-steel cores, laid in special forms, are poured under pressure with aluminum, which conducts heat well, but is not resistant to aggressive environments and high coolant temperatures. In bimetallic versions, aluminum does not come into contact with the liquid medium in any way and serves only as a heat exchanger. A design made according to this principle is ideal for installation in both central and autonomous system heating.

In some models, the core is made of copper, not stainless steel - such batteries are usually used for installation only in an autonomous heating system, where special antifreezes are used as a coolant. Steel pipes, even stainless ones, with some similar antifreezes "behave" not so adequately.

Water is not the only possible type coolant

Other liquids are used to dust the circuits of an autonomous heating system, in addition to water - this may be due to the peculiarities of the operation of the system or the requirements of the boiler equipment. More about - in a special publication of our portal.

• Semi-bimetallic batteries

For semi-bimetallic radiators, the internal channels are made of different metals. So, vertical pipes can be stainless steel, and horizontal pipes can be aluminum, as in conventional aluminum radiators. There is also the reverse. In a word, they do not “pull” on full-fledged bimetallic ones.

Be careful - instead of full-fledged bimetallic radiators, there is a chance to purchase lower-quality and reliable semi-bimetallic radiators

This type of battery is not suitable for central heating, since the coolant there often does not differ high quality and fashion to contain a sufficiently large concentration of alkali. In contact with aluminum, such a composition can cause corrosive processes, which, among other things, will “seize” steel elements installed in combination with aluminum. In addition, the differing thermal expansion of these metals can even cause the elements to move when subjected to extreme high temperatures, which is fraught with the occurrence of leaks and even more serious accidents.

Such radiators are often confused with bimetallic ones - outwardly they are generally indistinguishable. Not really understanding the intricacies, they are often preferred because of the more affordable cost. However, as can be seen from the description, they differ quite significantly in their reliability.

In extreme cases, a semi-bimetallic type of radiator can be installed in an autonomous system. But still, if it is decided to make the heating of a house or apartment as reliable as possible, then it is better to refuse semi-bimetallic radiators, and opt for real bimetallic samples. Be sure to consider this when buying.

Monolithic or sectional bimetallic radiators

As already noted, collapsible bimetallic radiators are produced, which consist of sections fastened together with nipples, and monolithic non-collapsible ones.

AT sectional version each of the sections inside the horizontal pipe segments has a multidirectional thread on both sides, designed to screw in the connecting nipples with sealing gaskets.

This design is the main significant disadvantage of sectional batteries, since these joints can be damaged from, for example, low-quality coolant, which significantly reduces their service life until the next preventive intervention. In addition, leaks most often occur at the joints of the elements, under the influence of high temperatures and high pressure in the system.

To avoid these unpleasant moments, another technology for the production of bimetallic radiators was thought out. It lies in the fact that first a one-piece welded copper or steel manifold is made, which fits into special form and pressurized with aluminum. These bimetallic batteries are called monolithic.

And this bimetallic radiator is a monolithic assembly

Both types have their own strengths and weaknesses.

The lack of a collapsible scheme has already been mentioned. And the main advantage of such batteries is that if one of the sections is damaged, you won’t have to change the whole one completely, since it is quite enough to make a bulkhead - to replace or simply remove only the failed element.

In the event of any leakage in a monolithic radiator, it remains only - they have practically no maintainability.

Selective comparative characteristics radiators of both types are shown in the table:

Often the decisive criterion is the question of cost. The fact is that monolithic type radiators has more high price than sectional, and this difference can be up to 20%.

When using monolithic bimetallic batteries, it will not be possible to vary the total thermal power- reduce or increase the number of sections. Therefore, before purchasing them, it is necessary to carefully calculate how much power is needed to heat a particular room. It will not be difficult to choose the right option, since monolithic bimetallic radiators are produced in different sizes both in length and height.

When choosing between sectional and monolithic batteries, the features of the heating system should also be taken into account. For example, if they are planned to be installed in an apartment of a high-rise building, then it is better to choose a monolithic type of device, since the pressure in the heating system of high-rise buildings is often quite high, water hammer is not excluded. and connecting nodes of sectional batteries may not withstand it and leak.

Selection criteria for bimetallic radiators

When choosing a specific model, in addition to the characteristics already mentioned above, there are other points that will directly affect the quality of the heat exchange devices and the duration of their operation.

• The design of the radiator must withstand water hammer and high pressure. This is especially important to consider when installing them in central system heating. Be sure to pay attention to the test pressure indicator.
• The battery material must be inert to the aggressive environment of low-quality coolant with increased level alkali or acidity. This factor also mainly applies to batteries installed in multi-storey buildings.
• The material of manufacture must also resist the occurrence of electrochemical corrosion.

• Radiators must be resistant to mechanical impact, that is, their outer casing must have sufficient strength. To check the quality of the aluminum used ( aluminum alloy), you need to try to bend the rib with your fingers. In a poor-quality product, the ribs bend easily, and sometimes they can even crack or break.

• Internal ribbed channels should be made of one metal, and it is better if it is high-quality stainless steel.
• Wall thickness inner pipe should be at least 3÷3.5 mm.
• Quite a few important element in the sectional design of the battery, there are gaskets, since the reliability of the connections will depend on their quality and elasticity, so they are most often made of rubber or silicone. Check quality sealing ring You can bend it several times with your fingers. If the gasket is rigid and inelastic, then it is clearly not enough for a long time.

Particular attention to the quality of the nipples - they must be made of durable steel

• High-quality steel nipples should be installed in the sectional radiator, in which the internal “antennae” will not break when the sections are twisted and the thread will not “gobble up”. The fact that the nipple is of poor quality can be recognized by the softness of the metal of manufacture.

If this element is of poor quality, then when the battery is unwound or twisted, the key hooks will definitely break off, and then the nipple will have to be sawn with a grinder, and then its parts removed from the section holes.

• The width of the front part of the radiator fin should not be less than 70 mm, since if this parameter is smaller, the heat transfer from the device is significantly reduced. It is best if the size of the section in the section is 80 × 80 mm - such parameters are guaranteed to give high heat transfer.

Optimal depth and width of sections - about 80 mm

Some manufacturers use a marketing ploy - they reduce the price of their products by reducing the size of the sections, which significantly reduces the overall thermal power of the device. Therefore, when choosing a radiator, it is advisable to have a tape measure or ruler in your pocket - so that you can control the optimal size.

• For a high-quality battery, the thickness of the protruding ribs should be at least 1 mm.

If the thickness of the fins is less than 1 mm, then this most likely indicates an insufficient quality of the product, since the strength of the radiator casing is reduced in it, and the heat transfer is not so high - due to the low heat capacity of too thin heat exchange plates.

But on this model, the thickness of the ribs is clearly underestimated - it's worth considering ...

• You also need to know that if a manufacturer saves on high-quality nipples and gaskets, this indicates that the entire product, with a probability close to 100%, is not of high quality, and it is better to immediately refuse it.
• You should not buy devices for which the manufacturer gives guarantee period only 1 ÷ 2 years, despite the fact that the service life of bimetallic sectional batteries is 25-30 years, and monolithic ones - even about 50 years. Such a small guarantee suggests that the manufacturer himself is not confident in his products.

Advantages and disadvantages of bimetallic radiators

positive their qualities are as follows:

• Bimetal radiators fit perfectly into modern interiors both residential and office space.

• This type of radiators is often produced with different color design. If not found desired color, self-coloring is allowed. For this process, special heat-resistant paint formulations are used that can withstand temperatures up to 150 degrees.
• Smooth surfaces and rounded corners make these radiators safe enough from the point of view of the possibility of injury, and therefore suitable for installation in children's rooms.
• The advantage is a fairly long guaranteed service life, subject to the choice of high-quality radiators and their correct operation.
• Bimetallic radiators can be installed in any heating system, even with low-quality coolant.
• This type of device, unlike other modern radiators, is able to withstand high intra-system pressure and temperatures up to 130 degrees.
• One of the key advantages of such batteries is a very high heat transfer.
• Such devices, as a rule, are equipped with a thermostat, which allows you to set the desired temperature for their heating. Its adjustment occurs almost immediately, due to the small cross-section of the channels.
• The number of radiator sections for each particular room can be easily calculated independently using the mathematical formula that will be given below. Correct calculation will help to avoid extra costs when buying radiators, their installation and further operation.

Reading time: 1 minute

Any heating battery will over time heat your living space worse and worse. The reason for this is its gradual pollution from the inside. The coolant also contributes a lot to it, which, when circulating through common system brings in your radiator" strangers» pollution. How to flush the heating battery in order to return its former useful amount of heat to it? We will tell you about the features of both external and internal cleaning.

Let's decide why we need to spend time and effort cleaning the radiator. Flushing is needed in the following cases:

• During a tactile examination, you determined that the battery warms up unevenly - one part is colder than the other.
• Compared to other seasons, your apartment warmed up an order of magnitude slower ( especially if neighbors do not notice this in their homes).
• The heating main is hotter than the radiators.
• For private houses, energy resources for heating have increased, while heat transfer has remained the same or even decreased.

Thus, in your house without cleaning it will become colder and colder every season, taking into account the fact that you will pay the same money for heating.

Types of batteries?

We first need to decide on the types of radiators in order to take into account their features before washing the batteries. At the same time, you need to come to terms with the fact that all batteries will have to be cleaned sooner or later - regardless of what they are made of.

Advice! Purge and flushing of radiators is carried out only at the end of heating season.

What to wash first?

Many people wonder if the battery needs to be washed from the outside first, or better first deed to clean it from the inside? We advise you to start external cleaning: remove all dust from the radiator, and if it is in the kitchen, then, possibly, a fatty film.

After you remove the battery, you need to clean the wall, floor, fasteners from dirt and dust - everything that was hidden from you by the radiator. And after that, with a calm soul, move on to internal cleaning.

Outside

How to rinse cast-iron radiators, as well as all others with them? You can put the radiator in order from the outside in several ways - it all depends on the degree of its contamination.

Dry cleansing

Everything that we will tell here is more suitable for everyday cleaning. For the general one, more serious methods are needed. So, there are two simple and effective ways:

1. Use of a vacuum cleaner. It’s very good if you have special nozzles - after all, battery sections are sometimes very close to each other, so you can’t get close to them with a regular floor brush.
2. Use of a hair dryer. In this case, a damp cloth of suitable size is attached between the wall and the radiator. The air from the device is simply blown out of the dust between the sections of the battery onto this fabric. Then it remains to carefully remove the matter and rinse it from dust.

Wet cleansing

How to wash the heating battery when it is very dirty? If you want to conduct a quality general cleaning, then you are here. First of all, we focus on the degree of contamination of the radiator:

• Light to medium soiling. Before wet cleaning it is best to carry out dry, which we described above. It is desirable to use hot water, even boiling water. Be sure to find a container of suitable size that can be substituted for the entire duration of the battery - water will flow there. Further, from another container, section by section, the battery is carefully poured with boiling water. After water drains from it, it is additionally dried with prepared rags and napkins.

• Flushing areas between sections. To wet cleaning touched areas between sections that we cannot physically reach with our hands, it is best to use a steam mop ( on the picture). Some housewives additionally spread cotton napkins for better steam absorption. As an option, you can wind a rag on a pointer, stick, narrow handle, nozzle from something and, wetting it in water, clean hard-to-reach areas.

• Strong pollution. Anti-fat agents are used. An aqueous solution is preliminarily prepared from them, which is poured into a spray bottle, a spray bottle and carefully sprayed over a moistened battery. Then some is given for “kissing”. After that, the washing solution is completely removed with water, rags from the surface of the battery.

Preparing for flushing

Before washing the heating battery, you must first do the following:

1. It is better to start such flushing before the start of the heating season - it is advisable to choose a day when the housing services have already completed the purging of the heating main, but the water has not yet been released. Perfect option- if you agree with all the neighbors in the riser about a one-time cleaning of the radiators in your apartments. So for sure you will not leave pieces of mud plying back and forth with water no chance.

1. Prepare a container where the remaining water from the heating main will drain after dismantling, first put it in the right place
2. Dismantle the radiators using a suitable plumbing tool. Remove them from the pins.

1. All plugs must first be removed from cast iron batteries.
2. Cleaning is best done in the bathroom. It needs to be prepared for this: lay rags inside so as not to knock down the enamel layer, but on drainer put on a special mesh. This is necessary so that large particles of dirt do not clog it.

Advice! If the risers are clogged in an apartment building, then there will be little sense in flushing the radiator - the dirt again, after a while, will fill up in it. It is necessary to negotiate with neighbors on a comprehensive purging of the highway.

Detergent

How and how to wash radiators? Of course, when cleaning the radiator, we will not manage with water alone. The following substances and solutions will be effective and useful:

• Alkali.
• Means for washing vehicle radiators.
• Lemon acid.
• Caustic soda.
• Acetic acid. Some also use essence ( 70% solution).
• Milk serum.
• Cleaning agent sewer pipes like " Mole».

Caustic Soda Whey
Washing agent car radiator Essence
Lemon acid

Imagine what the cleaning procedure will look like under different conditions.

Washing with a special device

For fast and effective cleaning radiators " without leaving the checkout» There are special devices for washing them. Of course, having such a device for infrequent cleaning of a home battery is, in fact, a luxury.

The device works from the mains - with a powerful jet it drives water into the radiator, which, with its pressure, removes scale, rust, grease, and various chemical deposits. But if this device you don't have, it can be replaced by cleaning the radiator in the bath.

Bath Rinse Algorithm

How to flush the batteries in the apartment without being able to pull them out into the street? The instruction will consist of the following blocks:

1. Hot water inlet. You will need to use a hose, a shower, a watering can, a kettle with a narrow spout, or an ordinary funnel to pour hot water into the radiator. Open both plugs so that dirty water can flow freely from them. After there is enough liquid in the battery, shake it and pour out all the contents. The action should be repeated until large pieces of dirt fly out of the cleaned radiator. It is worth noting that the procedure is difficult to perform alone - the weight of the battery is significant even for a brave athlete. Therefore, 1-2 assistants in this matter are vital for you.

1. Filling with cleaning agent. The second step is to pour the flushing agent you have already chosen into the radiator, diluting it with water. Now it is important to put plugs on all the holes in the battery so that " useful liquid” did not expire from it. Depending on the drug, it is left " turn sour» for a period of 2 hours.
2. As soon as the time of action of the active component has come to an end, it is necessary to shake the radiator again. You can knock on its various parts with a wooden, plastic, rubber mallet. This will help to further remove rust and other contaminants from its internal parts.

1. Now it is important to thoroughly wash the cleaning agent. Therefore, you need to clean it until the foam stops coming out, the smell stops being felt, or the rest appear in a different way. character traits its presence. If you do not flush the radiator to the end, then the active components of the product will continue to act, destroying the metal from the inside, which will cause leakage and failure of the battery.

The videos in this article will show you how to follow the instructions visually.

Features of cleaning in a private house

Flushing batteries in your homes is even more important than in apartments. This is due to a number of features of heating:

• The coolant is water from a well, a well, or even a reservoir. Hence the large dirt stuck in the radiator, it contains more than in the water circulating through the highways of urban heating systems. Therefore, the need for cleaning arises much more often.
• Washed ( blown through) not only a radiator, but also a heating main. After all, all the debris stuck in it will invariably fall into the cleaned battery.
• In case of urgent need, you can clean the radiator during the heating season. In a different state of affairs during the cold period, it makes no sense to turn off the heating system for cleaning.

Features of flushing during the heating period

If you decide to clean the battery in the cold season, then pay attention to the following:

• cleaning method, as detergents, the same ones are used.
• It is possible to flush the radiators ( in a private house), without removing them and without draining the water from the heating boiler:
  1. Turn off the steam line completely while cleaning.
  2. Perform a purge.
  3. Put all the valves back, then let the water through the heating circuit.
  4. Feed it until absolutely clean water flows out of the pipeline.

The measures taken will clean not only the radiator, but the entire heat pipeline in general.

Thus, it is possible to clean the radiator without removing it only in own house. Residents of apartments to clean the battery from the inside will have to remove it. An exception for those who have a special apparatus for cleaning batteries.

Finally, I would like to present you with a number of useful tips:

• Cleaning one radiator without the entire heating main is practically useless. Dirty water will soon cause rust, scale and other deposits to it. It is better to first order the cleaning of the entire riser for the entire apartment building, then take care of your radiator.
• It is better to flush the battery at least once every 3 years. After all, 1 mm of scale gives the same effect as a heat-insulating layer of the same thickness!
• Some craftsmen use this trick: at the inlet of the pipe to the radiator, they install a drainage system with magnets placed in it, at the end of which a plug is attached. As you may have guessed, rust from the coolant is attracted by magnets, which does not allow it to clog the radiator. The plugs are periodically removed to clean the outlet from corrosion products.
• If you are not confident in your abilities, it is easier and safer to turn to professionals who have necessary equipment and experience in such work.

That's all we wanted to tell you about how to flush radiators inside and out. As you can see, the procedure is not the most difficult. Difficulties are caused only by the weight of the radiator.

Heat in the house is impossible to imagine without a good heating system. To maintain comfort, you need to sometimes take the time to care for the batteries. Modern bimetallic radiators require only that they be cleaned from time to time from dust and dirt. But on old cast-iron batteries, sometimes you still need to renew the paint. Let's talk about how to properly care for cast iron batteries heating.

cleaning

You can wipe the radiators with a regular long-handled brush. To do this, soak the brush in water and clean out all the dirt. Next, gently wipe all the elements of the radiator by wrapping a dry rag around the brush.

Even more convenient way cleaning radiators - flushing the battery with a spray bottle (nowadays, small household water spray bottles are sold in hardware stores in large assortment, for every taste").

Process

Type water into the sprayer, put more rags (rags) under the battery or place a basin. With a sharp jet of water, you will perfectly wash away dust and dirt from hard-to-reach areas of the battery. After washing, wait until all the water has drained and wipe the battery again with a dry cloth. That's all!

Painting

Batteries of the old type require painting from time to time. For this purpose, it is necessary to use a special enamel or paint for radiators and heating systems. modern paint for radiators, when dried, withstands significant temperatures (as a rule, resistance to temperatures of + 100ºС), and thanks to special additives white enamel on a painted battery will not turn yellow.

Process

Prepare small brushes (including long-handled ones) and/or paint sprayer (see paint or enamel package for recommendations on choosing paint tools).
Clean the surface of the battery from dust, scrape off rust and flaking old paint. Degrease the surface with acetone. Those parts from which you will remove the lagging old paint, sand with sandpaper.
Mix the enamel thoroughly, then paint the battery in accordance with the recommendations on the paint package (often the surface should be painted in two layers with a break of 24 hours).

Important: all work with varnishes, paints and enamels must be carried out only in a well-ventilated area or on fresh air. Put on before painting rubber gloves and goggles for the eyes.

Heating systems often clogged due to the ingress of various debris into them, poor water quality and a high content of minerals in the coolant.

Lime deposits, corrosion and clogging of batteries significantly reduce the efficiency of the system.

When is it necessary to flush bimetal radiators?

• Uneven heating. A hot top and a cold bottom of the appliance indicate a blockage inside the equipment.
• Slow heating. When starting the heating system, the batteries take longer to heat up than usual.
• Low temperature radiators with hot pipes.
• Increased energy consumption.

How to properly clean your device

Smooth inner surface doesn't get dirty as fast, as in similar products made of cast iron or aluminum. Metal appliances for space heating are durable and require general flushing once every 5-7 years. Preventive cleaning should be carried out annually.

Choice of funds

Special chemical substances are fast and effective way cleaning heating equipment from pollution. The components that are part of the preparations break down deposits on the inner surface and contribute to the washing out of dirt.

In addition, you can use these folk remedies :

• solution caustic soda;
• seventy percent vinegar essence;
• whey.

Experts advise using only special chemicals for cleaning metal heaters.

Battery flushing

Batteries are easy to clean in large containers. Given the low weight of the products, the best option will be the processing equipment in the bath. First cleaning carried out without the use of chemicals. The radiator is filled with water and dirt is mechanically removed from it by shaking.

Photo 1. Before performing any procedures, shut off the water supply to the radiator using ball valves.

Waste content instrument should pour out, and in its place pour special reagents . The solution is inside the battery about an hour, after which the equipment knock with a wooden mallet or shake to remove rust and dirt. At the end of the device rinsed in running water .

Features of cleaning at home

In addition to flushing metal equipment, you should completely clean the heating system at home. For this you need bleed all the air and pour into the circuits chemicals . Water with reagents must be driven through the pipes until a visually clear liquid flows.

Important! The main cause of battery clogging is the use of unfiltered water from a well or well.

In private houses, due to the untreated coolant, flushing of heating systems should be carried out 1-3 times a year.

Cleanliness of radiators is the key to effective home heating

Flush batteries preferably after the end of the heating season. This will prevent the formation emergencies, breakdown of the heating system and premature failure of devices. Manipulations related to cleaning radiators, do not take much time, effort and money, but provide energy savings and a comfortable indoor atmosphere.

The word "radiators" has its root in the Latin "radio" (radiate), but we are much more accustomed to calling radiators batteries. Batteries are an important element of heating systems, and, perhaps, not a single room can do without them in the harsh Russian winters.

The main function of the radiator is to provide heat to an apartment, cottage or office during the cold season. The principle of operation of the radiator is quite simple: the coolant, moving through the heating system, reaching the radiator, slows down the movement and radiates heat into the room.

Models of radiators are produced a large number of, and they are classified according to several criteria: by manufacturers, by technical parameters, according to the material of manufacture, by type.

New models of radiators are constantly appearing, which are manufactured using new technologies and compare favorably with their predecessors with improved characteristics and design.

Modern models are designed to function for decades thanks to the developing methods of metal processing.

The choice of a specific radiator model should be carried out taking into account the parameters of the heating system as a whole, of which it will be an element.

Contrary to popular belief that radiators during operation require only cleaning from dust and sometimes painting, it should be noted that following the rules for caring for radiators can significantly extend their service life.

At the end of the heating season, employees public utilities for the purpose of prevention and repair, the coolant (usually water) is drained from heating systems. During this period, all radiators (with the exception of cast iron ones) may be exposed to corrosion on internal surfaces. This trouble can be prevented. To do this, close the valves on the direct and return pipes and open the Mayevsky valve (air vent). As a result, the coolant will remain in the radiator, and high blood pressure, formed during thermal expansion, will be discharged through the Mayevsky valve.

Subsequently, you need to perform the reverse procedure, that is, close the Mayevsky tap and open the valves on the supply pipes.

Radiators, with the exception of cast iron, are recommended to be flushed every two years. To do this, close both valves and open the Mayevsky tap, drain the water through a plug or drain valve. Then you need to remove the radiator from the brackets by unscrewing the connections. Flushing is carried out with a hose put on a water tap. The pressure must be good. When washing, do not use any abrasives. And, of course, remove accumulated dust from the surface, as it delays heat transfer. If you would like to follow this recommendation, but are not confident in your abilities, then invite a plumber who will professionally perform this work.

Painting of heating radiators

Cast iron radiators require periodic painting. In this case, use a special enamel designed for heating batteries; it contains additives that allow it to withstand temperature regime up to 100 degrees, the enamel itself does not turn yellow.

Observe safety requirements when working with varnishes and paints: work in a ventilated area, use protective gloves and goggles.

Bimetallic and aluminum radiators do not require staining, they have a completely aesthetic appearance in themselves, in addition, their coloring will reduce heat transfer. It must be remembered that protective screens also reduce heat dissipation.

Compliance with these simple rules will allow you to significantly extend the service life heating radiators. Well, at the end of a short video on how to choose heating radiators.
