The radiator is a necessary link in the heating mechanism of a private dwelling or apartment. He is responsible for keeping the room comfortable and warm. Therefore, when choosing it, it is necessary to take into account not only the cost and external performance, but also specifications one product or another. After all, if the characteristics declared by the creator of the radiator are not the same in reality, then the device will soon wear out and break down simply inevitable.

Main characteristics

In a private house, unlike high-rise buildings, an autonomous heating mechanism is being installed, that is, a system that does not depend on a conventional boiler room in any way. For this reason, the temperature of the coolant, as well as the network pressure, will be completely different.

When you choose heating batteries to be installed in a private house, a number of factors should be taken into account:

• In buildings of this type, the pressure on the coolant, tanks and radiator pipes will be significantly less. In fact, radiator batteries will not experience such loads, which is why you can pick up any model, even with thin walls.
• In buildings of this type, the length of pipes from the heat source to the radiator is small when compared with multi-storey buildings. For this reason, heat losses are practically zero, and the heat carrier will heat up more. That is, in a private house, models should be installed that will withstand such temperatures.
• It takes quite a bit of liquid to fill such a heating system. If desired, ethyl alcohol and antifreeze can be added to it. So you can make protection for radiators and pipes if the boiler does not turn on for a long time.
• Even the slightest possibility of the occurrence of so-called water hammers is excluded. True, in private-type houses, a problem may appear, expressed in the freezing of water in pipes. This will cause the batteries to simply burst if a person forgets to drain the water from there before leaving.

When choosing heating radiators for a private house, you should start from the main parameter - the area that you are going to heat. In the same cottages, the space requiring heating will be large, and so will the energy costs. It is best to install such batteries that will allow for high-quality heating with a minimum of heat costs.

Kinds

It should be said that heating batteries are various kinds. And here we are talking not so much about their shape and size, but about the material from which they are made. After all, it is no secret to anyone that various metals have different indicators heat transfer, due to which the coefficient useful action batteries can vary greatly.

If we talk specifically about the types, then there are radiators:

• from cast iron;
• aluminum;
• bimetallic;
• vacuum;
• of steel;
• quartz.

Now let's talk about each type in more detail.

Cast iron

The models in question have been installed in our homes for over a hundred years. They are still in great demand today due to the fact that they provide high-quality space heating. They were also among the most popular in the USSR.

If we talk about their advantages, then we should name:

• long operating period;
• excellent thermal performance;
• high strength, since batteries can easily withstand high pressure inside and easily endure mechanical stress;
• work even with poor quality coolant;
• are resistant to corrosion.

At the same time, cast-iron models have a number of disadvantages:

• large dimensions, which significantly complicates transportation, maintenance and installation;
• low thermal conductivity due to the massiveness of the metal and the fact that its surface is porous;
• batteries need systematic and constant care - painting and maintenance;
• walls should be good mounts for their installation;
• occupy a large area.

In addition, cast iron models are not very attractive. appearance, which almost always distinguishes them from the interior is not in the best way. Therefore, it is often necessary to put additional decorations on such radiators.

Steel

If we talk about this type of radiators, then they are divided into three categories:

• panel;
• from sections;
• from pipes.

Steel panel batteries are also called convectors, because heat is supplied precisely with the help of the convection process. They usually have a rectangular shape, which is formed by two welded panels. The coolant moves between them through special channels. Such a radiator has a small weight, small dimensions, which makes it possible to heat up for short term and maintain a good temperature.

If we talk about the shortcomings, then the main problem is poor resistance to mechanical damage and not very good pressure indicators. In addition, such models are very susceptible to corrosion.

In terms of characteristics, steel batteries from sections are somewhat similar to cast iron batteries, although they have a number of serious differences:

• the pressure inside here is at the level of 16 atmospheres;
• due to the presence of welded joints, radiators have increased strength;
• long service life - up to 50 years.

This type of radiators is not very common, because their significant drawback is high price. Tubular steel batteries are similar in functionality to sectional and panel radiators, but their price will be even higher. main reason This is that they have a rather pleasant appearance, which allows you to find a model for the interior. Yes, and on such batteries it is extremely convenient to dry things, which will be important for families with small children.

Aluminum

Aluminum belongs to the category of metals that conduct heat very well. For this reason, such radiators can provide full-fledged heating of almost any room.

Their advantages are:

• excellent thermal performance;
• small sizes;
• good pressure of the working type, which ranges from 12-18 atmospheres;
• small mass.

The coolant in radiators of this type circulates very well, which allows for excellent heat transfer. Such circulation is possible here due to the presence of free tubes of the inter-collector type. On the market, such models are quite widely represented.

The cost of aluminum batteries will depend on the manufacturer, but in general, it is quite affordable due to the low price of aluminum itself. In addition, such models have an attractive appearance, which makes it possible to consider them not only as a heating device, but also as part of the interior of the room. Thanks to its strict and neat geometric shapes, such a battery can easily fit into any interior.

But aluminum models also have their drawbacks:

• they are extremely sensitive to the quality of the coolant, which is why they require water filtration installations;
• very susceptible to serious pressure drops, so you need to constantly monitor its level;
• rather poorly resist the formation of corrosion, even despite the presence of a protective polymer-based coating;
• have a short service life - no more than 15 years.

In addition, the positive return of such batteries is not always an advantage. The good work of such a battery drives warm air up, which accumulates near the ceiling, which can cause a sharp temperature drop. Therefore, before buying such batteries, you should calculate the amount of heat needed for the room.

Aluminum batteries are divided into three categories, which will differ from each other in terms of device and capabilities:

• Sectional arranged. Their device makes it possible to replace plates that have broken.
• Whole. They have a solid construction and are flexible.
• Combined. They combine the best of the two categories mentioned above. Considered one of the best solutions for owners of their own homes. If you fully comply with the operating conditions, then such radiators can last 10-15 years and will really effectively heat the house when it is cold outside.

Bimetallic

Usually, inner part such radiators are made of steel or copper, which allows them to work well and enhance safety. And the outer side is usually equipped with aluminum fins. To date, bimetallic batteries are considered best solution in this domain. According to manufacturers, their batteries can last about 40 years. At the same time, they have a high cost, but still their characteristics have ensured them an excellent position in the market. It is advisable to buy such solutions if the issue of price is not the main one. But they will definitely pay back the money invested and will work for quite a long time.

vacuum

Began to gain popularity recently vacuum type batteries. When compared to other types, they have a number of advantages. For example, they require a smaller amount of coolant, which will come into contact through the wall with a special solution based on lithium and boron, which has a boiling point of +35 degrees. Also, these radiators have excellent safety features.

If you name other advantages, then it should be noted:

• reduction of the coolant level for the functioning of the mechanism by 80 percent;
• reducing the use of coolant from a centralized heat supply mechanism by a factor of three;
• if induction boilers are used, up to 40 percent of electrical energy can be saved;
• to carry out the installation of such batteries is quite simple even independently;
• in radiators there is absolutely no corrosion, as well as air jams;
• no need to use powerful circulation pump ny unit due to low local resistance;
• high heat output.

Quartz

Heating appliances made of quartz are a novelty in this segment. This type of battery can not be called high-tech, because it is an extremely simple option. Using batteries of this type, it is possible to make an efficient, reliable and economical heating mechanism in the room that will maintain heat in winter time. The quartz radiator will fit into any interior of the house.

Its design is simple and is a monolithic plate, inside which a heating element is built, made of a chromium-nickel alloy. The slab is made from a special solution based on quartz sand. The use of such sand is not accidental, because it can give off heat for a long time, which it previously accumulated. Even if such a radiator is disconnected from the heating network, it will be warm for a long time, which will significantly reduce electricity consumption.

If we talk about the advantages of this type of battery, then we should name:

• Profitability. A small consumption of electrical energy is the main advantage of quartz heaters, because other solutions consume significantly large quantity electric energy and their other advantages simply come to naught, because the price of electricity is quite high.
• significant heat capacity. A quartz slab has a rather serious thermal inertia. It heats up for a long time and cools down slowly, as already mentioned above.
• Durability. In this case, the heating element does not come into contact with the environment, which prevents it from oxidizing and significantly increases the service life.
• You can connect a thermostat, which allows you to get automatic control of the heating system.
• Quite a low cost when compared with electric-type water heaters or other heating devices.

• Fire safety. The temperature of such a battery will not exceed 95 degrees, due to which the ignition of materials that are near the heater is completely excluded. This allows you to mount the device on almost any surface, including wood, plastic and drywall.
• Electrical safety. Such a battery does not create serious loads on the power grid and can operate smoothly throughout almost the entire season.
• Just installed. The quartz battery is attached to the wall with brackets.
• They do not require maintenance and do not require serious maintenance. The only thing to do with such a battery is to wipe the dust off it.

Popular manufacturers and reviews

In the segment of cast iron models, the most famous manufacturers are the Chinese companies Tokio and Konner. not bad domestic model such batteries will be MS-140.

If we talk about steel panel solutions, then the products of Korado, Buderus and Lideya are considered to be of the highest quality. But tubular steel solutions are usually produced foreign companies. Among them, Zehnder, Arbonia and Delonghi products should be highlighted.

Aluminum batteries are produced by both foreign and domestic companies. Among them are well-known manufacturers like Global, Ferroli and Rifar.

Bimetallic models are produced by both foreign and domestic firms. If we talk about domestic ones, then we should name the Teplopribor brand, and if we talk about foreign ones, then these are products of the brands Polywarm, Sira, Royal Thermo Vittoria and the German company Kermi. When choosing ceramic batteries, you should pay attention to the products of the Teplako brand.

Now let's talk about the experience of using different types of batteries by users and their feedback. This is logical, because manufacturers often say one thing, but in practice we get something completely different. If we talk about cast iron radiators, then users note that even beautiful solutions not easy to install and they have a rather serious mass. In addition, they often require additional brackets to be installed.

Let's talk about aluminum radiators in more detail, having read the reviews of users of batteries of various brands. If we talk about aluminum batteries from Sira, users note that they heat up well and have an excellent appearance. Also, users note the good heat dissipation of models. But many are not very happy with the considerable cost of solutions from this company. Users also praise such batteries from Global and note that they heat well in combination with a boiler and have an excellent appearance. The same applies to solutions from Rifar.

Users also do not ignore bimetallic batteries and generally speak very flatteringly about them. For example, Rifar batteries look great in various interiors, are quite strong and can withstand a lot of pressure, as well as high temperature coolant. In general, it is impossible to make any clear rating of radiators, because they all have a number of their positive and negative sides. One thing can be clearly noted - in any case, it should be individually determined which batteries in a particular private building will be the best solution.

Which is better to choose?

If you want to choose an economical option for a country wooden private building, then it is best to install high-quality aluminum radiators. These solutions have everything you need: modern design, ease, affordable price, and their negative aspects are not so serious in the conditions of an autonomous heating mechanism of a private house.

If money is not such a serious matter, then it will great solution installation of sectional-type bimetallic batteries, especially when it comes to a copper-aluminum combination. And if there are small children in the house, then in order to protect them and the rest of the household, you can opt for convection options, completed with certain protection options. If it is necessary to hide the radiators, floor convection solutions can be used.

If the house has a stove with a water circuit, the simplest solid fuel boiler or your house is equipped with gas heating, then you can use time-tested cast iron batteries. Despite the fact that their choice entails difficulties with installation and weight, at the same time they can significantly smooth out temperature fluctuations and store heat for a longer time. And now you can easily pick up options with a nice design, if you can afford them.

Installation rules

Radiator heating in own house- a guarantee of comfort and coziness in autumn and winter. It is good when such a mechanism has already been connected to a centralized heating mechanism. If something like this is not there, then it becomes necessary to use autonomous heating. If we are talking about how to install the heating system with your own hands correctly, then it should be said that the most important element there will be a choice of options for connecting radiators in a house of their own construction.

A number of people do not even suspect that this plays a very significant role in the heat transfer of the heater, the circulation of the heat carrier inside it and the speed of movement. hot water. The above as a whole will have a significant impact on the effectiveness of the entire mechanism.

The first thing to deal with is piping. It can be called important point, because the residents of their own houses at the stage of their construction are rarely able to clearly and correctly calculate the costs that will be made to form the heating system, therefore, they have to make savings on various kinds of materials. Typically, the pipe connection method can be either one- or two-pipe. The first option is economical, in which a pipe is laid from the heating boiler along the floor, going through all the walls and rooms and which returns to the boiler. Radiators should be installed on top of it, and the connection will be made using pipes from below. At the same time, hot water flows into the pipes, completely filling the batteries. Then the water descends and through another pipe enters the pipe. In essence, it goes serial connection radiators thanks to bottom connection. But there is a minus, because at the end of such a connection in all subsequent radiators, the temperature of the heat carrier will be lower.

There are two ways to solve this moment:

• connect a special circulation pump to the entire mechanism, which allows you to distribute hot water evenly over all heating appliances;
• connect additional batteries in the last rooms, which will increase the heat transfer area to the maximum.

If we talk about two-pipe wiring, then for your own home, such a connection system will be more effective. But at the same time on initial stage the costs will be significant due to the fact that it will be necessary to carry out a divorce of two pipes. One must be installed to supply hot water, and the second must be connected to drain it.

When everything became clear with this issue, you should stop your attention on the scheme for connecting heating batteries. The most common will be the side. To make it, pipes should be led out to the side of the wall and connected to two battery pipes - top and bottom. From above, a pipe is usually connected that supplies the coolant, and from below - the output. A diagonal type connection will also be effective. To perform it, you must first connect a pipe supplying a coolant to the nozzle at the top, and a return pipe to the lower one, located on the other side. It turns out that the coolant will be transported diagonally inside the radiator. The effectiveness of such a mechanism will depend on how the liquid is distributed in the radiator. It is rare that several battery sections can be cold. This happens only in cases where the ability to pass or the pressure is rather weak.

Note that the connection of the radiator from below can be not only in single-pipe, but also in two-pipe versions. But such a system is considered extremely inefficient. In this case, it will still be necessary to install a circulation pump, which will significantly increase the cost of creating a heating mechanism and create electricity costs that are needed to operate the pump. If you say what you don’t need to do, then this is not to replace the water supply with a return line. Typically, the presence of this problem shows debugging.

When installing decorative screens, the visibility of the thermostat is blocked, which is not necessary. Batteries will take a long time to warm up. At the same time, you cannot mount the thermostat head in vertical position, because this will lead to its unstable operation.

Do-it-yourself installation of heating radiators in your own home is associated with a number of points, which do not give to say that this is an easy process. Its complexity also lies in the fact that in each individual case it is necessary to select batteries for a particular building, and also to know exactly how pipes pass in a private house that has already been built. Also, an equally important fact will be understanding the needs for heating and making all the necessary calculations.

In addition, we should not forget that there are various connection schemes and what may be inefficient in one house, in another will be a great solution. If you decide to do the installation of heating radiators yourself, then you should carefully study the theoretical points, and if possible, at least consult with a specialist who will tell you what you should pay special attention to during the installation of radiators and the heating system as a whole.

Installation and maintenance of a double-circuit gas boiler Ferroli Diva

Dual circuit gas boilers Ferroli Diva F24/C24 are designed for heating and hot water supply. Versions with open and closed camera combustion.

The heat exchanger of the heating circuit is made of copper, coated with a heat-resistant aluminum-based composition for long service life and against corrosion. The heat exchanger of the DHW circuit is made of stainless steel and allows for a high rate of water heating.

Location of the Ferroli Diva F24/C24 boiler

The combustion chamber of the device is hermetically isolated from the environment, which allows you to install the boiler in any room. However, the room in which the boiler is installed must have sufficient ventilation to prevent dangerous situations in case of even small gas leaks.

This safety standard is mandatory for all types of gas-fired equipment, including devices with a so-called sealed chamber.

According to the standard, the unit can be operated in a partially protected area at an ambient temperature of at least -5°C.

It is recommended to install the boiler under a roof slope, on a balcony or in a niche sheltered from the weather. In any case, the installation site must be free of dust, flammable objects and materials, or corrosive gases.

The Ferroli Diva gas boiler is designed for hanging on the wall and is supplied complete with a hanging bracket. Fasten the bracket to the wall following the dimensions shown in the illustration on the cover of the manual and hang the boiler on it.

By special order, a metal template can be supplied to mark on the wall the points of enlightenment of the fixing holes. When mounted on a wall, the boiler must be firmly and securely fastened.

If the unit is to be installed among furniture or sideways to a wall, allow enough space to remove the cover and carry out normal maintenance work.

Hydraulic connections

The drain hole of the safety valve must be connected to a funnel or drain pipe to prevent water from spilling onto the floor in the event of an increase in pressure in the heating circuit. Otherwise, the boiler manufacturer will not bear any responsibility for the flooding of the room when the safety valve is activated.

Before proceeding with the connection of the Ferroli Diva F24/C24 boiler to the gas supply system, make sure that the boiler is set up to operate on the type of gas available and carefully clean all pipes of the system Make connections to the appropriate fittings according to the drawing on and in accordance with the symbols available on the unit itself .

In case the hardness of the water exceeds 5°, the water used must be properly treated to prevent the formation of scale in the boiler.

Freeze protection system, antifreeze liquids, additives and inhibitors

The use of liquid antifreezes, additives and inhibitors is permitted, if necessary, only and exclusively if their manufacturer gives a guarantee confirming that his products meet this species use and will not harm the boiler heat exchanger and other components and / or materials used in the construction of the boiler and system.

It is forbidden to use liquid antifreezes, additives and inhibitors that are not specifically designed for use in thermal installations and are incompatible with the materials used in the construction of the boiler and heating system.

Connection of the Ferroli Diva F24 / C24 boiler to the gas pipeline

The gas line must be connected to a suitable point, in compliance with current regulations, using a rigid metal pipe or seamless flexible stainless steel hose.

A gas valve must be installed between the gas main and the boiler. Check the tightness of all gas connections.

Electrical connections

The device must be connected to reliable system earthing, made in accordance with current safety standards.

The effectiveness of the earth loop and its compliance with the regulations must be checked by qualified personnel. The manufacturer does not bear any responsibility for damage that may be caused by the lack of grounding of the apparatus.

The internal electrical connections in the Ferroli Diva F 24 boiler have already been made; it is also equipped with a "Y" type power cord without a plug.

The electrical connection must be made in the form of a fixed connection, equipped with a two-pole switch with a contact spacing of at least 3 mm.

The section between the boiler and the power supply must be protected by fuses with a maximum current of 3 A. When making electrical connections, it is very important to observe the polarity (PHASE: brown wire / NEUTRAL: blue wire / GND: yellow-green wire.

The user is not allowed to replace the power cable by himself. In case of replacement of the electrical cable, use exclusively a 3x0.75 mm2 cable with an outer diameter of 8 mm or less.

Before proceeding with the installation gas boiler Ferroli Diva check that the diaphragm used is correct and that the maximum allowable length is not exceeded using a simple calculation:

Finalize the layout of the split ductwork, including accessories and outlet tips.

Determine the loss in meq (equivalent meters) on each component depending on its location.

Check that the total resistance value is less than or equal to the maximum allowable value.

If it is required to connect the boiler to a collective chimney or to a separate natural draft chimney, such chimneys must be designed by a professional, in compliance with the requirements of current legislation, and must be designed to work with units with a closed combustion chamber and a fan.

In particular, such chimneys must have the following characteristics:

Have dimensions calculated in accordance with current standards.

Ensure tightness and absence of leakage of combustion products, be resistant to the effects of combustion products and temperature, be impervious to condensate.

Have a round or square section, be laid vertically and have no bottlenecks.

Have chimneys that ensure the removal of hot products of combustion to the required distance from flammable materials or their isolation from them.

Be connected to no more than one unit on each floor.

Be connected to only one type of unit (all must be either forced draft or natural draft).

Have no mechanical means of suction in the main air ducts.

Have a vacuum along the entire length in stationary operation.

Have a chamber at its base for collecting solid residues or condensate, equipped with a hermetically sealed metal inspection hatch.
