How to wash radiators – Sometimes it happens that the radiators suddenly start to work is not too effective . In this case the neighbors and their temperature in the riser is much higher. This may mean that the radiators are clogged . In this situation , only one – washing equipment.
Cleaning the pipes in a city apartment
In town to wash the battery should only be at the end of the heating season. It can be done by yourself , but not highly desirable . The fact that even in the warm season in the central heating system and water can be stored in its dismantling the risk of flooding neighbors.
The very same flushing procedure did not represent a daunting . Master, in addition to standard plumbing toolkit will need aid for flushing radiators. Battery spun from the pipes ( input and output ) and remove . Next to it you will need to enter a special chemical solution to soften the hard deposits. Then washed with water from the radiator unit under pressure. If such equipment is not present, the surgery is performed through a hose attached to the faucet .
Cleaning the heating system in a country house
In the country house is a problem , as the blockage of pipes and radiators worth even more acute than in urban apartments . All the matter here in a dirty ( relatively solids) of water reservoirs or wells . In this case, self- flushing will be much more effective because you can not only clean the battery itself , but also all the pipes . In this case it is necessary , first of all, open the valves and let out the air , as to pull air from the battery correctly read the link above :
– The water inlet valve that feeds the firebox ;
– Feed valve reserve capacity ;
– Circulating valve jumper ;
– Crane pipe through which water flows into the radiator ;
– Crane near the distributor ;
– The handset reverse .
Of water to produce the boiler itself is not necessary. On the reverse link at the boiler inlet valve must be closed. Steam piping line on the rinsing closed. The water is fed into the system as long as the drains are not pour clean. In that case the house three circuits prior to wash the second and third valves are all close to the ground . Thus, the entire system is cleaned , including radiators.
Reagents for the dissolution of the solid raids heating radiators
To dissolve the solids inside pipes strikes and batteries can be used the following materials:
– Whey . After using additional equipment rinse water – washing agent for automotive radiators ;
– Concentrated alkali, for example, ” The Mole .” Leave for a day , then rinse with hot water .
Flushing heating equipment – operation is not too complicated , but requires accuracy . Most importantly – do not make a flood and ruin equipment .
Calculating the number of radiator sections – Not all residents of homes can boast that they have heat in the apartment. Quite often not heat radiators for sale in sufficient quantities so you have to freeze. Out of this situation : I have to replace old radiators with new ones.
In most old houses are cast iron radiators, which are durable . They can serve you for years, but since rust in the radiator heating system grind for many years , their heat output decreased significantly . Besides CHP not always heats water sufficiently , which directly affects the temperature inside the apartment. And if so , then it’s time to replace radiators with new ones, so you no longer have to freeze .
Today the market is the most popular are bimetallic and aluminum radiators . They have high heat , and thanks to the epoxy coating the inside of the radiator sections protected from oxidation.
How to calculate the number of sections of the radiator
When installing the radiator is very important to calculate the number of sections . Requires it to maintain a comfortable room temperature for you , you do not have any freeze or sweat out the heat.
When calculating the radiator sections do not take into account of what exactly the material it is made . Whether you’ve got a steel bimetal or aluminum radiator , always repelled from one section of the power and area of the room you want to heat .
Power radiator sections are always specified in its technical characteristics . On average, it is about 180 watts. Note that output sections of different manufacturers to be more or less, so the calculation should take into account these changes .
To calculate the required number of sections need to know the area of each room, which will change the radiator . Suppose we want to change the radiator in a room of 18 square meters. m
The third value that we need – is the thermal power needed to heat one square meter of space . For rooms with high ceilings 2.5-2.65 m , this value is 100 watts.
From these data , one can calculate the required number of sections . To do this, multiply the area of the room to the desired heat output and power are divided into one section :
18 x 100/180 = 10
The result will be a necessary number of sections for heating one room . In this case the sections 10 . If you got a non-integer , then it is rounded toward greater . When calculating the number of sections for the kitchen radiator resulting number can safely be rounded to the smallest.
Installing a radiator
When calculating the number of sections should also take into account some of the nuances of the characteristics of the radiator and space. For example, this calculation is valid for a room with a door and window . If there is no room in front of a glazed loggia or whether it is a corner , then to the resulting number of partitions you want to add another 20%. In the rooms with new windows from the number of sections obtained safely subtract 15%. In the case of the battery inserted in the same niche or screen heat losses amount to 15-20%.
As you can see , to calculate the required number of sections radiators per room is not so difficult as it might seem . And if you are not confident in their calculations , it does not hurt to consult a specialist .
How to choose a good radiator
Radiators for heating for many years enjoy a special prevalence in the market. And all because they allow you to increase comfort and coziness in the premises in the cold season. It should be noted that these devices are presented in a wide range. Therefore, before making a purchase, it is important to deal with some points.
First of all, I would like to talk about the materials for the manufacture of radiators. Of course, first of all, we should mention cast iron, which gives the finished products a special attractiveness and durability. If we talk about budget models, they are endowed with flat neat surfaces and compact dimensions. As for retro models, they, in turn, are equipped with a special pattern, due to which they become a stylish addition to the interior.

If we talk about the main advantages of cast iron radiators, corrosion resistance, heat retention for a long time and a long operating period deserve special attention here. But the disadvantages include the complexity of installation, as well as the excessive volume of the coolant.
A steel radiator for heating is also particularly common in the modern world. And all because it has a low cost, as well as a diverse and stylish design. In the presence of clean water in the system and optimal acidity, such batteries are able to serve faithfully for twenty years. Their indisputable advantage is minimal inertia.
Also recently, bimetallic radiators have begun to appear on the market, which have an aluminum shell and steel durable pipes. Thus, they easily withstand different pressures. In addition, unlike aluminum analogues, such devices are not subject to corrosion.
Whatever it was, steel radiators, which have a modern design, minimal weight and excellent heat dissipation, have a large number of advantages. In addition, they are presented in panel and tubular versions. In the first case, we have to talk about structures consisting of special welded sheets with oval recesses. At the same time, their number may be different. In fact, such panels are widely used in children’s and medical institutions, due to their ease of cleaning.
Tubular type radiators, as the name implies, consist of vertical pipes. They are distinguished by an increased pressure margin, high cost, as well as an interesting and original design.
What radiator choose? Aluminum or steel? – Steel panel radiators are in demand due to the optimal ratio of parameters such as price, thermal power and appearance.
One of the attractive features of this type of heater is compatible with virtually all materials used for the installation of heating systems, and multiplicity of applications.
This thermal appliances, It is nice for a working pressure of 8.7 atm, the test – 13 atm and a maximum flow temperature of 110 ° C. Especially often this type of radiator used in low-rise building individually.
Not recommended to use them in systems with multiple excess operating pressure: multi-storey buildings with central heating.
Branded steel radiator brand always takes 2-3 levels of processing and surface protection. He degreased and treated in zinc phosphate bath, passes the painting cataphoresis bath, then powder coated epoxy paint (on a scale of colors RAL 9010). Ends the process of drying and processing of high-bake paint.
Double zinc phosphate coating plus guarantees enamel surface protection against corrosion of the radiator and external influences. Increased thermal capacity of the steel radiator is achieved by spot welding to the convector coolant channels and reduced fin pitch panel.
The distances between the axes of coolant channels is not more than 25 mm. This improves heat transfer by 15-18% and reduce the cost per 1 kW of thermal power generated.
A wide selection of sizes of steel radiators allows you to choose them according to the installation conditions. Overall height is 300 to 900 mm. Overall length of 400 to 1500 mm in steps of 100 mm, and from 1600 to 3000 mm in steps of 200 mm.
Radiators, steel fasteners have a special system that allows you to install them so that the bottom connection fittings can be positioned on the left or right side.
Radiators can be connected to one or two pipe heating systems. They can be equipped with thermostatic valve. With their choice, be sure to learn a moment that they are sensitive to the content of oxygen dissolved in the coolant, so the range of applications only closed heating system. Corrosion of steel radiators increases sharply after draining the system.
Aluminum sectional radiators
This type of radiator is designed to work in systems with high pressure.
The main advantage of aluminum radiators – a material having a high thermal conductivity with low thermal inertia. Therefore, such a device responds quickly to heat loss in the room and well controlled thermostatic valve.
Aluminum radiators are made by injection molding. They operate flawlessly in such heating systems where no differences coolant acidity (pH of water is in the range of 7-8) and no surges of pressure and temperature. To exclude electrochemical corrosion at the connection points of aluminum sections with steel pipes should use special galvanized adapter.
Pleasant aesthetic feature aluminum radiators are their personal items with a convex line, producing the effect of light and shade. Therefore, these radiators look great in any design decision.
One of the reform for an apartment or House to replace the heating pipes. Harder than this, planning the installation of heating pipes of floor screed application. Ideally there should be no joints between lengths of pipe, according to experts. Usually the cost of installation of the heating system professionals. This fact can’t think about installing heating pipes.
The easiest way to install heating pipes
Installation on the wall of heating pipes in most cases the best technical and most economical when you refresh and renew. The most simple in implementation is the installation of polypropylene pipes. This distinctive feature is easy, flexible and polymeric composition. To install heating pipes by yourself will need bass: theoretical knowledge about the process in General, several video – instructions for installing pipe, steel welding, accuracy and a little patience.
And do not represent an increasingly complex process. First, you need to cut the pipe cutter, then heat the welding unit, then fix the connection, in the end, the cool layers related to the natural way. Business is not complicated, but requires attention and.
Installation of heating pipes. Types of heating pipes
Easy to install whatever the form room; both thermal and sound insulation in one safe, secure installation heating pipes. If you want to replace your heating system in an apartment, and then choose the type of pipe should be treated with the utmost responsibility. Is the main thing to look at articles that are made. In this case also takes business approach, as small literacy on the pros and cons of each material. So, for example, pp is the durability, steel, have the highest rate of heat transfer, attracting metal flexibility and simplicity in operation.
Plastic tubes. May require the installation of this type of professional skills. But the score multiplier, and will pay you half-forgotten problems with heating. Moreover, system maintenance will cost almost nothing.
Steel tube. Working with this type of pipe welding machine, means that carries its difficulties. You will also need a large number of connections and threaded connections, and today very unreliable. The installation is very time consuming, under power of experienced professionals. Another very heavy metal pipes, a big disadvantage, with the automatic installation of the heating system. Also this type of pipe has a limited lifespan and reduce the corrosion durability.
