Hot water, without interruptions current from the crane, is one of the signs of comfort of any room. However, the Russian reality is such that far from always people can use hot water all year round
Domestic inconvenience will help solve the installation of an economical gas water heater.
Gas water heater - This is a device for heating water from the water supply system due to gas combustion energy. At the same time, such an energy and balloon (liquefied) gas can act as a "supplier" of this energy.
1. Cumulative gas water heater ( gas boiler).
This type of gas water heaters is a container (reservoir), from which hot water pipes diverges to water-treatment points - cranes.
The reservoir of the accumulative gas water heater, depending on the model, has a volume of from 10 to 500 liters and is made either of the steel coated coated or glass fluorophore, or from stainless steel with titanium coating.
One of the main advantages of accumulative gas water heaters BAXI is an opportunity at one point to use a large amount of hot water even during a complete shutdown of the water supply system. At the same time, access to the water heater accumulated water is carried out without any delays in time.
Unfortunately, as in any technological device, a cumulative water heater has a disadvantage associated with the fact that hot water remaining in the pipes between the tank and the crane cools over time. For this reason, many users of cumulative water heaters are forced by opening the crane, wait until "go down" cooled water.
Solve this problem helps the installation of a circulation system, which consists of a small pump connected by a pipe of a small diameter with a system of pipes, along which water from the tank falls to the cranes. The pump pumps the remaining pipes, but not used by the consumer water back into the container, thereby preventing its cooling.
2. Flowing gas water heater ( gas column).
In fact, flow gas water heaters are high-speed heat exchangers having a form of copper spirals or stainless steel plates. The principle of their work is as follows: Cold water flow from the water supply system enters the body of the gas column, inside of which, due to heating, the water temperature rises. The temperature of the water is set by the consumer using a manual regulator, water heating time from 3 seconds to 2 minutes. Depending on the model, the flow gas water heater transmits the consumer from 10 to 27 liters of hot water per minute.
The main advantage of the flow gas water heater lies in the ability to provide hot water in an area not limited to the tank. Also, in contrast to accumulative gas water heaters, flowing relatively small and, as a rule, do not require specially equipped rooms.
However, when operating flow water heaters, it is necessary to pay attention to pressure drops in the water supply system. Insufficient water can lead to overheating of the heat exchanger and, accordingly, turning on the protection and blocking of the burner. Thus, while the pressure in the water supply is not normalized, water will be very difficult to heat.
Flowing water heaters consume fuel only during use, that is, direct heating, hot water, which makes them more economical than accumulative water heaters.
Gas water heaters, regardless of the water heating principle, are equipped with combustion chambers, which, according to the nature of the output of fuel, there are two types - closed and open. In the combustion chambers open type The process of combustion of fuel occurs under the action of natural thrust that the need to ensure the continuous inflow of fresh air into the room, where the gas water heater is located.
The main disadvantage of the water heater with an open combustion chamber is that after its installation in residential premises that are not equipped with additional ventilation, there is a lack of air, a sensation of stuffiness and carbon monoxide. For this reason, it is necessary to allocate for such equipment a separate room.
In gas water heaters using a closed combustion chamber, air supply is performed outside the room with the help of the so-called coaxial chimney, which is simple design "Pipe in a pipe."
During operation in such a chimney, gas combustion products are thrown through an internal, narrower tube, while air for the camera operation is on the outer tube. The movement of fuel and air combustion products is carried out using a small electric fan.
Gas water heaters use different kinds Gas hilt in the burner, which, in general, can be divided into 2 groups:
1. Poggig gas with duty phytyt.
A semi-automatic system (piezorozhig and electrojig) is used in water heaters with duty phytyt. The ignition in this case is carried out by one click of the button.
Water heaters with such a type of ignition consume more fuel, part of which burns in duty wick.
2. Poggig gas without wick.
In this case, the ignition occurs automatically with the help of hydrodynamic or electronic stages. With this signal to turn on and starting water heating, it will only be the opening of the crane consumer.
In general, the approach without wick is most convenient and profitable for the consumer, because it provides gas savings to 15%.
Automation.
Gas water heaters of various types are equipped with controlling and protective automation of different levels of complexity.
Protective devices, as a rule, are automatic valves that instantly cut off the fuel supply to the main burner. The protection of protection occurs automatically in the following cases:
- cessation of water flow through the heat exchanger or a decrease in pressure in the water supply system;
- failure or malfunction in the gas hilt system;
- Lack of or weakening thrust in chimney.
In addition to protective automation, experts are recommended to install stabilizers on gas water heaters, which help to control the power of water flow, maintain the temperature specified by the consumer, as well as to a large extent noise level of equipment.
The automation of controlling character, which is installed on the water heaters, includes thermostators and coordinatrollers. The thermostat is designed to control the temperature of hot water and usually represent an additional control panel on the water heater housing. But in some models of gas water heaters, thermostators have the form of a remote console with a moisture-repellent coating.
CommoditTrolls allow the consumer to set the temperature at specified time intervals and completely turn off the water heater when hot water is required. These devices are usually installed only on accumulative water heaters.
By purchasing a gas water heater, the consumer faces the need to prepare a point where the system will be installed. Depending on the type and dimensions of the water heater, it can be a separate room or a specially equipped place (part of the wall, angle, etc.).
The room intended for the installation of the water heater should have a ceiling height of at least 2.2 m, and the volume of at least 8 m3 for equipment with an open combustion chamber and at least 6.5 m3 for a system with a closed-type camera.
Regardless of the type of combustion chamber near the place to install the gas water heater, the ventilation canal should be located outside the room, or at least an indirect hole for air flow (gap between the floor and door, grille, etc.).
The room in which the water heater will be installed, must be heated and have protection against frost. Otherwise, water in watershed pipes and the tank will be frozen, which will damage the equipment.
The wall on which the water heater will be mounted should have a non-combustible coating so that heating does not lead to a fire.
In general, it should be noted that the most optimal place for the placement of gas water heaters of a small size is a kitchen or room near the waterproof points. For cumulative water heaters of large volumes, basements and semi-luminous rooms are best suited.
Manufacturers and suppliers of gas water heaters often require the installation of equipment to be carried out exclusively by the staff of their service service. It should be noted, such a requirement is quite reasonable, as the employees familiar with the models of the company's water heaters can perform high-quality and safe installation of the system.
Most of the operation when installing the gas water heater is to connect to the gas and cold water, as well as in the installation and adjustment of automation. Gas is summarized to the system with copper or steel pipesequipped with gas cranes and mechanical filters against contamination. On the pipe, which comes with cold water, the cutting crane is mandatory, overlapping during the equipment accident. In addition, the gas water heater system is mounted check valvewhich prevents the return of heated water into the water supply system.
The amount and equipment of the equipment that can be additionally installed on the gas water heater depends on its view, such as combustion system and fuel features (natural or liquefied gas).
Gas water heaters, like all sorts of complex technical devices, require periodic inspections to ensure their effective work. Service maintenance It can be done both by the Seller specialists and employees of the company providing this kind of service.
The frequency of technical inspections depends on the complexity of the equipment, but cannot be less frequently than 1 time per year.
Summing up this article, it is worth saying that gas water heaters are ideal for providing hot water on a permanent basis and is beneficial from others with their economy, convenience, durability and independence from electrical network. Gas water heaters are equally successfully used for both domestic and economic needs in the presence of a natural or liquefied (balloon) gas.
The Russian market presents a large range of equipment of domestic and foreign manufacturers with great choice models.
Acquire gas water heaters, it is necessary only in a new state, checking the availability of all certificates and permissions from the seller. Installation of equipment should also be entrusted to exclusively qualified specialists with licenses and work permits.
With flow heaters, everything is clear - gas columns work much more efficiently electrical analogs.
Yes, and from the point of view of payment of the accounts "Gas" hot water supply looks more attractive than the "electrical" option. Any homeowner will agree with this opinion.
However, in the case of cumulative heaters, boilers - such unity of judgments is not observed. Therefore, in this article we will try to find out what is better: a gas or electric boiler.
Gas water heaters
Any boiler consists of identical nodes:
At the same time, the gas boiler differs from the electrical cumulative water heater only with the design of the heating element. At the electrical appliance, a high-resistance tubular conductor is used as a heater, heated when connected to the network.
Heater gas device It works more difficult. It consists of a gas burner embedded in the cylindrical combustion chamber, which is "part-time" also with a gas duct, discharged combustion products beyond the housing. At the same time, the gas duct is embedded in the tank-drive - he permeates his through, like a samovar tube. That is, the burning gas heats the air in the gas duct, which, in turn, transmits the temperature of the water in the tank.
Scheme internal device Gas water heater
As you can see: the heating element of the electric boiler is simpler than the similar node of the gas instrument. but gas-burner It works for years, not burning and not rusting from water. Yes, and the surface area of \u200b\u200bthe gas plant is much greater than the similar parameter of the TEN.
As a result, the gas boiler works with greater efficiency than an electrical analog. While the tan is heated by a couple of liters, the water gas burner can boil 3-4 times the larger volume of the liquid.
So this round remains behind a gas boiler.
The dimensions and weight of an electric and gas boiler, designed to maintain the same fluid volume in the tank, are approximately equal. Therefore, the process of fastening the boiler on the reference surface will be absolutely identical in both "gas" and in the "electric" case.
Boyler's insert in a hot and cold water supply network is carried out by typical scheme, common and gas, and for electrical accumulative water heaters.
Installation of a gas water heater
But the connection of the "energy line" is implemented in completely dissimilar schemes.
The electric boiler simply "turns on" into the socket without asking for the permission of the energy company. The gas boiler is connected to the gas pipeline by enhancing the support of the appropriate service.
Moreover, both connection schemes are equally simple - even a beginner electrician or gas worker will be lit. However, due to excessive bureaucracy, the installation of the gas boiler will be much more complicated than the installation of an electric water heater.
Therefore gas cumulative boiler Loses this round "Perviously".
The electric boiler can be powder or explode due to the failure of a safety valve, which blends overheated steam. The gas storage can light up or explode due to gas leakage. So with the same bad problem, the owners of the electrical appliances and the owners of gas analogues will be.
Therefore, in the third round we have an obvious draw. Moreover, gas leakage from the burner is just as little likely, as well as the "breakdown" of electricity on the body of the tank.
Electric boiler Vaillant VEH 200/6
with a tank volume of up to 200 liters and a thermal capacity of 8.5 kW.
Electric boiler Vaillant VEH 200-6
Costs almost 80,000 rubles.
Gas cumulative boiler Vaillant VGH 220/5 XZU
Vaillant VGH 220-5 XZU
With a tank capacity by 220 liters and a thermal capacity of 8.5 kW.
Costs 90 thousand rubles.
That is, taking into account the 10 percent exceeding the volume of the gas heater over the electrical analogue, the price difference is carried out practically imperceptible.
However, on small volumes, the price difference is still noticeable. For example, a 150-liter boiler
ARISTON ABS PRO ECO PW 150V
ARISTON ABS PRO ECO PW 150V
there are no more than 20 thousand rubles.
Ariston SGA 150 R
Ariston SGA 150 R
it will cost 35 thousand rubles.
The difference in value is obvious. However, almost all "small" boilers - up to 150 liters - they work not only as water heaters, but also as boilers heating.
Boiler boiler gas Baxi. Nuvola 3 Comfort 280 Fi
Kothel wall-mounted Baxi Nuvola-3 Comfort 280 I
not only heats the room to 280 "squares" but also retains the supply of water to 60 liters.
Taking into account such a nuance price of 66 thousand rubles
no longer seems to be translated, because for 40-50 thousand (the residue less than the cost of a 60-liter boiler) of a decent boiler with a thermal power up to 28 kW can not be bought.
Consequently, after a stubborn struggle, having received unexpected reinforcements from manufacturers, the gas boiler takes leadership in electrical heaters.
It's time to consolidate success. Gas water heaters go to the offensive and knock out electric water heaters! Judge for yourself: to warm up the 150-liter tank to 45 degrees Celsius already mentioned Ariston ABS Pro ECO PW 150V spends 4.5 hours, spending 11.2 kW of electricity. That is, the cost of heating, taking into account the tariffs of 2015, will be 55 rubles.
A more expensive ariston SGA 150 R to warm up the same tank of 150 liters to the same temperature, spends a little more than an hour (71 minutes), consuming no more than 720 grams of liquefied gas or 0.8 cubic meters of the main fuel. That is, the cost of heating will be only 25 rubles.
As a result, the gas boiler Ariston SGA 150 R simply knocks out the electric aRISTON WATER HEATER ABS Pro ECO PW 150V, leveling the difference in cost for 600 hours of operation.
According to the result of the five rounds in the account leads a gas boiler. It is more efficient than the electric heater (the water heating rate reaches 20 liters per minute), but harder in the installation (the official permission of the gas service is necessary). But on the security of the advantages there is no one model. For the price, with a small stretch - the cunning of manufacturers, united the heating boiler and the boiler - wins the gas device.
At the cost of operation, electric water heaters were explicitly losing - the gas boiler costs twice as cheaper, and heats the water four times faster. As a result, gas storage heaters win the electrical analogues of the "economic" knockout in the fifth round after leadership in the overall standing throughout the "match".
Gas non-volatile cumulative water heaterdoes not require connection to electricity. The possibility of working at low pressure of water and gas, the device does not have restrictions on the minimum water pressure, has low hydraulic resistance, the pressure at the point of the water treatment is almost equal to the input. The ability to connect the recycling line allows to reduce hot water supply time in remote water-based points. The capacitive design of the water heater (the large surface of heat exchange) reduces the process of formation of scale, allows for a long time to operate the device without preventive acting. Control of the presence of a flame is carried out by a thermocouple, which makes the gas disconnection when the flame is disappeared. The device is adapted to work with low quality water.
Among the equipment for heating gas, the most famous South Korean manufacturer has long and successfully offers its product line. Consider gas boilers Daewoo, let's study, what are their features, how to connect them, which they have problems.
Of course, like all that is done under the brand of DEU, boiler equipment This brand is also made on summit. In the design of the aggregates of DEU, the following advanced technologies applied.
All these advantages provide additional comfort to consumers and simplify the rules of operation of the Gas Boilers of DEU. Among the aggregates of the described Korean brand are common families as:
To finally make sure how high-quality, multifunctional and safe equipment produces Daewoo, we analyze two specific brands of boiler equipment in detail.
We picked up for studying two popular wall-mounted basic models with two heating circuits. That is, these devices are installed on the wall, they have two contours - for heating and hot water supply.
Consider the subtleties of the operation of these two copies of the brand, and at the same time we will analyze typical malfunctions Such gas dual-circuit boilers DEU. It should be first noted that the models that we selected are the most commonly sold among all modifications of the described Korean brand.
This gas double-circuit boiler Dae is attached to the wall, it provides for the heating of hot water supply, its capacity is 11.6 kW, and the area of \u200b\u200bthe room, which he is capable of arguing with heat - 130 kV. m.
Let's see what major qualities are inherent in it.
These advantages indicate that the equipment of DEU is really multifunction and comfortable in control.
Detailed instructions on the DEU gas boiler described contains all the necessary information on the operation.
The main provisions of the instructions are as follows.
There are also several innovations applied in this model.
It is clear that all these advantages cannot but affect the price, the cost of such equipment is also not small, but we will talk about it.
It is also a wall-mounted double-circuit unit with a closed gas combustion chamber, the power here is higher - 29.1 kW.
Accordingly, the room can be missed large Square, namely - up to 290 square meters. m.
The advantages of this apparatus, in principle, repeat those inherent in the previous model.
Instructions for use on this Gas boiler Daewoo, in fact, repeats the instructions for the previous model.
Here are the main features.
These codes indicate the characteristic malfunctions of the Gas Boiler DEU, at which the gas burning is most often blocked:
Now we will reduce the information on two DEU units to the following table. Here she is.
It is easy to understand from this table that the cost of the described equipment is not so great, if we compare it with the price of equipment of other eminent brands, in particular, German or Italian origin.
Now let's talk about the characteristic faults of the Gas boilers of DEU.
What is more common, and how to deal with it.
Most cases of appeal to repairmen, as shown years of operation of this technique, is associated with the wrong first launch. Therefore, this stage, when installing, you need to pay special attention. It is necessary to follow each letter of the instructions attached to the technique.
Although there are little breakdowns.
The gas column will not only allow you to use hot water from several sources in one house and do not depend on problems or failures in the central system.
Flowing gas most often have small dimensions, they are the perfect choice for small apartments. The device is connected directly to the cold water supply system, it works both on natural and liquefied gas.
The principle of action of the column is very simple: water enters the heat exchanger, where heats up from the combustible gas, and immediately fed into the mixer.
The accumulative gas column can accommodate a large amount of fluid, so it requires a large space. The heater warms a certain amount of water in the tank and keeps the temperature for a long time.
If the water cools, the column automatically warms it to the desired temperature. Water tank is well insulated, thanks to which the water remains the longer hot.
Depending on the needs, you can choose a gas water heater with a liquid reservoir from 50 liters and above.
The semi-automatic type of columns is triggered only if you press the Piezorozaga button. Such a device increases the gas consumption, since the flame of the stobnant should always burn.
The burner with modulated power is automatically adjusted under water pressure and retains the initially displayed temperature.
Turbated devices are less popular because there is a risk of freezing of the tap low temperatures. In this case, you need to often tease the gathered water so that the heat exchanger does not explode.

A gas water heater for an apartment or a gasified house may not have the function of switching to liquefied gas. The main thing is that the security system is at the highest level.
For dacha the ideal option There will be flow models on a balloon gas, since the consumption of hot water is minimized.
The security system should include at least the most important points, for example, flame presence sensors, sensors from overheating and reverse thrust of the chimney.
The ignition system does not play a particularly important role. It all depends on your preferences and wishes. The same applies to size, colors and other external parameters.
The question is what low-temperature heating, many people occur. Typically, such systems are characterized by heating the coolant to 60 degrees Celsius. At the same time, at the entrance to the system, it has a temperature of about 40 degrees, and at the output - about 60. Consider how it is achieved.
Temperature mode heating systems Three characteristics can be described:
The boiler data must be indicated in the process of products in this sequence. The heating systems of the traditional type (including central heating) were calculated in such a way that water should have a temperature of about 80 degrees at a temperature of 60 degrees at the inlet. However, these days such indicators are somewhat outdated. The temperature can be reduced or heated, or by the user itself. European boilers, which today practically completely outlined Soviet heating analogs, work in several other schemes.
According to the European standard, the normal mode of operation of heating systems implies a temperature of 60-75 degrees Celsius. But here it is said about the concept of the so-called "soft heat", which involves the parameters of the system with a temperature of up to 55 degrees. And it is precisely this mode that can be regulatory in the near future, considering all tightening requirements for savings. In this way, installation of warm floors It is becoming increasingly relevant.
ABOUT " warm floors"Perhaps everyone heard. It is this system that acts one of the most striking examples of low-temperature heating. In addition, most of the owners of the private house today reduce the temperature of the boilers to "units", in order to bring the temperature of coolants to 50-60 degrees.
For installation of water warm floorsYou get the following advantages:
Eliminating the main sources of heat loss and wanting to reduce costs when after 5-10 years the system will pay off, household owners can start re-equipment of heating systems on more economical regime Work.
We build or reconstruct a private house, got involved in the boar of apartments. We equip the office, warm garage, heated room for other purposes. The heating system was thought out, the main equipment was picked up: the boiler and its strapping, a boiler, a warm floor system. Either, if it is an apartment, decided to replace the existing heating device More aesthetic and efficient, maybe add a few additional sections of the old battery. We assume that we have already made a choice of the type of heating instruments: a set sectional cast iron, aluminum batteries, bimetallic devices or ready-made panel steel radiators. Do not forget that the batteries must withstand the pressure of the coolant in the system, which in multi-storey building An order of magnitude higher than in the cottage. To achieve thermal comfort, it is important for us to correctly perform the calculation of heating radiators.
To ensure the necessary temperature in the room, the calculation of the power of heating radiators and the entire system must take into account the heat loss from each room and the climatic conditions of the region. Heat engineers in the manufacture of the project determine the thermal balance of the outer walls, roofs, the base of the building, window and door structures. Also taken into account air exchange in the ventilation system, the height of the premises, the movement of air flows and many other factors. The fundamental document prescribing the principles of designing the heating system - SNiP 2.04.05-91. Designers enjoy a number of regulatory acts (a total of up to two dozen), regulating the heating device for buildings and premises various destination.
The accurate calculation of the sections of heating radiators for all the rules is quite complicated, and make it yourself, without possessing special knowledge, not easy. During the construction of a serious country house, it makes sense to refer to the specialists and order a complete project of heating: rational solutions, thermal comfort and optimal fuel consumption are justified. If there is no such possibility, you can make an approximate calculation of heating batteries yourself.
Thermal power, heat transfer or heat flow of the heating device indicates the number of heat energy (in kilowatts or watts), which radiator or one modular element (section) is able to put into the room per unit of time (hour). Less often meets designation in calories / hour. One watt is 0.86 calories. The magnitude of heat transfer depends not only on the design of the radiator, its size, the material from which it is made. The parameters of the coolant are not less important: its temperature and the speed with which the fluid flows through the batteries. For most heating devices, thermal power is indicated with standard coolant temperature values \u200b\u200bat 60/80 ° C. Accordingly, when operating services from budget generaries are amenable to heat and launch boiling water into the system (rarely, but it happens), the heat transfer will increase. It will go a little warm water at low speed (it happens much more often) - drops. Significantly affects the magnitude heat flux and method of connecting the device.
It should be noted that not all connection schemes provide complete heat transfer of the heating device. The most common standard side (1), for other cases (3, 4), a downward coefficient is introduced during the calculation.
The heat transfer of one section in the traditional cast-iron radiator of the Soviet sample is 160 W. To determine the total battery power, multiply this digit to the number of sections.
Aluminum radiators are also sectional. The heat flux depends on the model, but with a standard inter-axis height of 500 mm, an average of 200 W for one section. That is, such aluminum sections will be required by about 20% less than cast-iron.
Aluminum radiator design. In the standard embodiment, the value A is 500 mm. Attention should be paid to distances from the external edges of the device to the floor and the windowsill. If they are less than the specified, heat transfer slightly down
Panel steel radiators are intimidable and have a fixed heat transfer. As an example: Depending on the design, a standard height panel and a length of 800 mm can give a heat flux from 700 to 1500 W.
In the central regions of Russia for the heating of the residential room with one outdoor wall in typical panel house It will take about 100 W thermal energy to one square meter of the square. This is a very estimated digit. If the apartment is located on the first or last floor, it is worth adding about 20%. For the corner room, increase the number one and a half times. Do not forget that there is a dependence on the connection scheme, if necessary, take into account correction factor. This is a battery of ten cast iron sections. Naturally, for Yakutia and the Krasnodar, the importance of heat transfer per unit area will differ significantly. Thus, for the Moscow region on a room of 16 m 2 in the standard "panel", 1600 watts will be required.
Modern house With walls from "warm" cellular blocks, and even with "thermoshube", energy-efficient glazing will have much smaller heat loss and the required radiator power should also be lower. Some sellers heating equipment Facilitate potential buyers the choice by placing a calculator on their website to calculate the number of heating radiators sections. With the help of this online service, it is realistic to make a more or less accurate calculation of the heating radiator on the room.
Radiators location plan, one of the plurality of the "right" project of the heating system. For each room, the design value of heat loss (numbers in a rectangle) is indicated. During the construction of expensive apartments to save on design work Not worth it
Preferably. You do not always get the coolant of the desired temperature from the HSA, so it is worth increasing the battery power by 20-25%. At the entrance It is advisable to put a heat regulator: a thermostat or a regular ball crane.
"Right" radiator installation (5). Thermostatic valve (4) Provides a permanent maintenance of a given temperature in the room, connecting parts (1-3) will help you quickly remove and install the battery back. Bypass (jumper between the supply and discharge pipe) will enable the heat carrier to circulate on the riser and when the device is removed, so as not to infringe the interests of neighbors around the house
In Europe, prevail, and in Russia modern low-temperature heating systems are increasingly used. They are built on the basis of energy-efficient condensation heating boilers, thermal pumps. To get the maximum economic effect for radiator heating, as well as for warm floors, use low temperature coolant - 40-55 ° C. The heat transfer of radiators is reduced by about 1.8 times. Accordingly, they must have greater power and dimensions. Despite the rise in the system, such an approach is justified: rationally designed, correctly mounted and competently adjusted low-temperature system makes it possible to achieve significant gas savings. BUT heat pumps Do not need fuel at all. To calculate such systems, all known manufacturers indicate the heat transfer of instruments for various parameters of the coolant. The calculation of the amount of heating radiators should also take into account the influence of warm floors.
The ratio of the efficiency of traditional and modern condensing gas boilers. To achieve this savings, the radiators should also circulate the coolant with a low temperature. Accordingly, the heat transfer of devices should be taken on the basis of indicators in 40-55 ° C
In conclusion, let's say that the heating device should not be closed with something: dense curtains, a solid decorative screen, closely the driven furniture will significantly reduce its effectiveness. If the fashionable windowsill completely closes the battery from above, the warm air passes the surface of the window glass, and it can be overlooked cold and "cry". In this case, the windowsill should be placed in the windowsill.
