What is the water temperature in the gas boiler

What to do if the boiler is constantly working and does not turn off

When operating a gas boiler, you can often encounter the problem of its excessive heating. Why is a hot gas boiler we will figure it out in this article. If you find that the body of the device has become warm or hot, it means that there was a malfunction. It must be eliminated as quickly as possible. First, you should immediately check the functionality of the burner. Its settings probably lost. As a result, a powerful flame appears, from which the heat exchanger overheats, as well as the upper part of the boiler. In this case, it is required to reduce the power of the flame.

In addition to this reason, heating may appear with self.discharge of gas boilers settings. Units are made in accordance with the power of the burner. Exceeding the recommended power leads to violations in the operation of the boiler unit. In this case, you should immediately resort to the help of a specialist.

Attention! Self.re.equipment of boilers is illegal and can lead to fires or explosions.

How the heating system works

The functioning of the heating system in a private house is ensured by the fact that water/antifreeze is heated in the boiler to the set temperature. The fluid is directed to the batteries from which the room is heated by the room. After that, the already cooled liquid comes back, where it is again subject to automatic heating.

The scheme of the heating system

The principle of operation of a double.circuit heating boiler

On the example of a gas unit, we consider the principle of operation of a double.circuit boiler. The design of the unit is a system of blocks, the work of which is interconnected and controlled by a security system, which includes various sensors. The main blocks are a gas unit, where ignition and burning occur, a hydraulic unit, which regulates the supply and pressure of the liquid, a smoke exhaust unit, diverting gas combustion products.

When the boiler is turned on, the circulation pump is originally launched, then gas is supplied using a gas valve. Automatic ignition lights gas, the heat exchanger heats up during the combustion of the gas, heating the coolant passing through it. In this mode, the unit will work for some time until the parameters that are regulated by sensors change.

Sensors control the temperature in the room, in the reverse stream, gas pressure, pressure in the system, traction flow, flame. Temperature sensors can adjust the temperature at the input or at the output of the heating circuit. If there is a sensor at the return when the installed temperature reaches the thermostat, the thermostat sends a signal to the electronic fee, which processed it, turns off the gas supply.

In this case, the circulation pump will work for some more time to cool the heat exchanger. This is done so that the remains of heat in the heat exchanger do not bring the coolant to boiling. After cooling to a given water temperature in the system, the electronic board will launch the pump, the gas valve will open the gas and the entire cycle of the double.circuit boiler will repeat.

When the tap with hot water is opened, the duct sensor is triggered and the control board switches the three.way valve to heating the secondary heat exchanger. Heating hot water in the system is a priority, t.e. Immediately after you opened the tap with hot water, the entire system will only work on heating this water.

When the crane closes, the reverse process occurs. the board transmits the signal to the three.way valve, it closes the hot water system and the unit again begins to work on the heating circuit. It should be remembered that the unit will need some time so that hot water flowing from your tap.

Some devices are equipped with the Fast Start or Comfort function. This function allows the boiler to switch the three.way valve from time to time and heat water in the secondary coolant.

The effect of temperature on the properties of the coolant

In addition to the above factors, the water temperature in heat supply pipes affects its properties. This is based on the principle of operation of gravitational heating systems. With an increase in the level of water heating, its expansion occurs and circulation occurs.

However, in the case of the use of antifreeze, the excess of the norm in the temperature in heating batteries can lead to other results. Therefore, for heat supply with a coolant other than water, you should first find out the permissible indicators of its heating. This does not apply to the temperature of the radiators of centralized heat supply in the apartment, since such systems do not use antifreeze fluids.

Antifreeze is used if there is a probability of a low temperature on the heating battery. Unlike water, it does not begin to move from a liquid state to crystal.shaped when 0 ° C reaches. However, if the heat supply is included in the norms of the temperature table for heating in the larger direction, the following phenomena may occur:

  • Foam formation. This entails an increase in the volume of the coolant and, as a result, an increase in pressure. The reverse process when cooling antifreeze will not be observed;
  • Formation of lime plaque. The composition of the antifreeze includes a certain number of mineral components. In case of violation of the rate of heating temperature in the apartment, their precipitate begins to a larger way. Over time, this will lead to suction of pipes and radiators;
  • Increase in the density.Circulation pumps may be observed if its rated power has not been designed for such situations.

Therefore, it is much easier to monitor the temperature of the water in the heat supply system of a private house than to control the degree of heating of antifreeze. In addition, ethylene glycol compounds during evaporation, I release gas harmful to humans. Currently, they are practically not used as a coolant in autonomous heat supply systems.

What should be the temperature of the boiler heating according to current norms?

GOST R 51617-2000 is valid, according to which the rate of air temperature in residential premises in the heating season should be in the range of 18-25 degrees Celsius. Accordingly, you can try several operating modes of the boiler by changing the temperature indicator to choose the most suitable.

We recommend that you prevent frequent and noticeable changes in the temperature regime. This is poorly affected by health and can disrupt the work of boiler equipment. If you want to save a little, you can put an indoor thermostat with the ability to configure the work schedule. For example, to establish that at night the maximum temperature in the room does not exceed 18-20 degrees, and in the morning the air warmed up stronger. By adjusting the gas supply, you can save good for the heating season without sacrificing comfort.

You can choose the optimum temperature for yourself. just determine at what mode of operation it is comfortable and fuel costs are the most rational. You can also get a consultation with a representative of the manufacturer. Or by specialists “Professoros”. We not only sell and install boiler equipment in Kaluga and the region, but we can also give recommendations for working with different types of boilers. To get a consultation, contact the Profetel manager by phone number 7 (4842) 75 02 04.

So, you open the hot water crane, your heating unit turns on, and almost boiling water comes from the tap. What is the problem? After all, you set a normal comfortable temperature.

Let’s look at how your heating devices work. If you use a colonk or a boiler, they work on the principle of flow heating. Here lies the whole simple secret of overheating. Most often, overheating occurs when you already used it to open the hot water crane. What happened?

As soon as you closed the hot water crane, the water was finging to flow through the heat exchanger in which it heats up.

At the same moment, the automation closes the gas valve.

The flame in the burners begins to decrease, it takes some time until it is completely faded.

The metal of the heat exchanger continues to transmit the heat of the non.moving water inside it.

During these few seconds, the water in the heat exchanger receives excess heating, which leads to its overheating.

Now that you are opening the hot water crane again, the part of the water that was in the heat exchanger and was overheated, inexorably moves to the exit from the system and stirring from the tap still pleases you with its own temperature.

That is, it is almost impossible to reduce to zero such an effect. Of course it all depends on the closing speed of the gas valve. If you have a gas column, you can personally check how quickly your valve works. Just watch through the window of the fabric, how much time passes from the closure of the tap of hot water, to the complete fading of the burner. If this time is less than 1 second, you are all right and it will not be better. And if the burner goes out for more than 1 second, perhaps this suggests that you need to clean, make a valve stroke or check the density of its fit. Only a huge request. do not do this yourself, gas reinforcement is not a joke, it is better to ask for a specialist.

In gas boilers with a bittermic heat exchanger, this problem of overheating is even more aggravated. Why? All because of the heat exchanger device. Such a heat exchanger is a pipe in the pipe. Your water flows through the inner pipe into the DHW system (the one you wash the dishes swimming. ), and the coolant from the heating system circulates through the outer pipe. The coolant is usually very hot, about 80-90 degrees. As soon as you swell the hot water crane, it stops leaking in the heat exchanger, but the coolant continues to transmit its heat to it. Thus, water heats even more than in the columns. In addition, it remains hot longer than in the columns, because it is inside the heat exchanger and is surrounded by another pipe with the coolant.

I will find that nobody likes to be scalded, but you can completely level this effect only in systems with storage containers. How to fight? Just let this water drain.

By the way, somehow I had a chance to observe the Czech column of Soviet times, in which the paint melted in front of the burner precisely because of the poor operation of the gas valve. The water was closed, the gas continued to burn, the heat exchanger overheated and there was so much heat that it was transmitted to the column body in such a large volume. Therefore, do not forget to check the gas devices in time, demand from the servicing servicemen that.

During the operation of a double.circuit gas boiler, each user will face certain problems associated with the operation of the hot water circuit. These problems are inevitable. They always appear, regardless of the boiler manufacturer and from its heat exchanger, from the features of the boiler design; It doesn’t matter if the boiler is wall or floor. Often the boiler begins to warmly warm hot water or not heat it at all. Especially when you use several points at the same time. Let’s talk in this material how to get rid of this problem forever.

Problems arising from the user

In any room where a double.circuit gas boiler is installed, whether it is an apartment, a country house or office, there are certainly several places that are points of water intake: a washbasin in the toilet, shower in the bathroom, washing in the kitchen. All these points are connected to the contour of the hot water supply of the boiler.

Double.circuit boiler is put on maintaining a certain temperature in the hot water supply circuit. When you turn on hot water at one of the points:

  • For some time, cold water continues to go from the tap, which stood in the pipe before its opening,
  • The heating of the boiler turns on, while a certain time is required so that it goes to a given temperature,
  • After a few seconds, heated water enters the pipe and begins to move to the fence point,
  • A few more seconds are necessary for hot water to reach the fence point,
  • An additional few seconds are necessary due to the fact that the received water seems to be too hot to the consumer, and it regulates the water supply to the mixer.

Thus, from the moment the hot water crane is opened to the moment the water supply that has a comfortable temperature begins at least a few seconds. The further the water fence point is located from the boiler, the greater this period of time.

All this time, the user cannot fully use water and he will be that the boiler does not warm normal hot water. He expects the moment of receipt of water having a comfortable temperature. Meanwhile, water that has a temperature that is not comfortable for the user simply goes into the sewer.

Unproductive water consumption can be from several liters to a dozen liters, depending on how far the water point is from the boiler.

Adjusting the temperature of a solid fuel boiler

The process of combustion of solid fuel is a complex and highly inertial process, and therefore it is very difficult to regulate. However, albeit rudely, but this process can be controlled by dosing the amount of air supplied to the combustion chamber.

The temperature of the solid fuel boiler is adjusted by changing the supply of air into the combustion chamber of the boiler. There are two ways of such adjustment:

water, temperature, boiler

Both methods have the right to life, but the first case is cheaper, and the second makes it possible to achieve high accuracy of regulation.

Regulation using a flap of air supply. this is a variant of passive power regulation. In this case, the air enters into the combustion chamber due to the traction (vacuum) that the chimney creates.

This method involves the presence of air supplies in the boiler. This damper can be located on the lower door of the boiler or in its posterior part. In addition to the damper, the boiler should have a place with an internal thread where the thermostatic traction regulator is screwed.

The traction regulator using the chain is connected to the air supply flap. This system works as follows. when the temperature of the water in the boiler approaches the temperature set on the traction controller, the rod of the sensitive element of the regulator is lengthened by the size sufficient to cover the damper within its working range.

However, the effectiveness of this method of controlling the damper cannot be high, and the regulator does not provide high accuracy of regulation. Since the process depends on many physical factors, for example, not every mechanical traction regulator can fully “lift” heavy cast.iron damper and t. P., Therefore, to achieve the accuracy and speed of regulation with such a system is almost impossible. The main advantages of this method are the low cost of the system and its energy dependence (no connection is required).

Practical recommendations for setting up the temperature of a solid fuel boiler using a thermomechanical traction controller

First you need to completely open the air supply flap (blown), melt the boiler and wait for the temperature to reach 60 ° C on the thermometer of the boiler. After that, it is necessary to set the gap of the air supply flap about 1-2mm using the adjusting screw.

Next, set a temperature of 60 ° C on the traction controller. either on a white scale or on red. depending on the mounting position of the regulator and pull the chain until it stops sagging (with a minimum stretch). Now you should experiment with the temperature on the regulator handle and the temperature supported by the boiler. Based on the results of tests, we adjust the length of the chain.

Adjustment of the temperature of a solid fuel boiler using a fan and controller

The second method of adjusting the temperature of the solid fuel boiler is to use the fan and controller, and it can be attributed to the case of active control of air supply. The essence of this method is to direct dosing the amount of air entering the combustion chamber of the boiler. The executive mechanism in this case is a fan that pumps air into the combustion chamber. By changing the speed of the fan, you can smoothly and in a wide range change the volume of air entering the combustion chamber of a solid fuel boiler. The controller controls the fan. The essence of control is a smooth change in the power supply voltage, depending on the difference between the given temperature and the one that is now in the boiler.

Consider the parameters that the standard controller can provide:

  • The final temperature of the boiler is a given temperature that automation should provide;
  • The hysteresis of the fan is the difference in temperature from the given, within which linear control of the fan revolutions (proportional law) will occur;
  • The minimum fan speed is the minimum speed in the operating mode (minimum heat power of the boiler);
  • The maximum turnover of the fan is the speed in the maximum power control mode (maximum thermal power of the boiler);
  • Flooding time is time, automation includes a fan when the boiler has gained a given temperature so that the flame in the boiler does not fade;
  • the time of the pause between the purges. so as not to overheat the boiler when it gained temperature;
  • The temperature of the inclusion of the heating system pump. the pump will be turned on only when the set temperature reaches;
  • Pump hysteresis is a difference showing how many degrees from the given temperature of the water in the boiler can drop without turning off the pump. Determines the temperature at which the pump will turn off;
  • Correction of temperature indicators. if the sensor is not mounted correctly and its indicators are incorrect;
  • The boiler repayment temperature is the temperature at which there is no longer fuel in the boiler and the fan turns off;
  • The test mode allows you to check the operation of the pump and fan in manual mode.
  • Controller
  • Fuel boiler
  • Board fan
  • Emergency temperature sensor
  • temperature sensor
  • Pump c.O.
  • Heat receiver-radiator

As you can see, this method of adjusting the supply of air has the ability to more accurately provide a given temperature of the coolant in a solid fuel boiler. However, with sufficient sealing of the air supply door and blowing, this automation system can lead to a boiler attenuation in the absence of power supply, because the air groove valve is mounted on the fan when the fan does not work, the valve does not allow air to supply air in the combustion chamber.

What is the cloak of a gas boiler?

A gas boiler clocking is the incidence of heating the heat carrier. If the equipment does not connect external control devices, then the gap between the inclusions of the gas boiler can be no more than 10 minutes. By default, the interval is 3 minutes.

It is not recommended to include equipment often. The most economical consumption will be with the continuous operation of a gas boiler. If the equipment has been working continuously for a long time, it means that the regime was configured in which the heat losses in the house were compensated when the suitable heat carrier is maintained.

Residents of small apartments often face the problem of large gas consumption. This is due to the fact that the equipment was designed for heating and heating of water, so it has high power.

Different models of Baxi gas boilers differ in configuration parameters, so you need to study the instructions before setting up equipment.

How to set up a boiler with your own hands

Why do you need the correct adjustment of the technique:

  • To save resources.
  • To be comfortable in the room, use hot water.
  • To extend the service life of equipment.

You need to start with the right choice of the boiler, its power. Consider the features of the room: the number and area of ​​windows, doors, quality of insulation, wall materials. The minimum calculation is carried out from thermal losses per unit time. You will learn more about this in the article “How to calculate the power of a gas boiler”.

Gas boilers are divided into single.circuit and double.circuit. The latter perform heating on the heating circuit and hot water supply (DHW). Single.circuit units provide only heating. Therefore, to obtain hot water, indirect heating boilers are installed.

By the type of technique, it is floor and wall. Units placed on the floor have great power. Therefore, they are used for large areas (from 300 m²). Installation is carried out only in separate rooms (boels). These are BAXI models (“Baxi”), Buderus (“Buderus”), “Navien”, “Kuits”.

Hinged devices (Neva Lux, Arderia, Daewoo, Ariston. Bosch) perfectly fit in small apartments in the kitchen. Therefore, it is important to take into account all the nuances of the location. The comfort of the residents depends on the correct selection of parameters, as well as the durability of the boiler.

Power setting

The heating force depends on the modulation of the gas burner. If you have chosen a device with electronic control, then it includes a thermostat that connects to a room thermometer. Adjustment occurs automatically: the thermometer measures the temperature in the room. As soon as it falls below comfortable, it gives a command to launch a burner or an increase in flame strength.

In normal mode, the thermometer controls the temperature in only one room. But if you install valves in front of each radiator, control will be in all rooms.

You can adjust the burner by hand by exposure to the gas valve. This is relevant for atmospheric boilers with an open combustion chamber. So, in the models of Protherm “cheetah”, “Bear’s Bear”, the valve is adjusted to the electric motor. To change the settings, you need to go to the service menu. Most often this is done by the specialist, and the user performs the actions specified in the instructions.

But still we will tell you how to call a hidden menu for adjustment.

Before you go to the menu and set up, do this:

Energy efficiency. combi boiler

  • Unscrew the taps on the batteries.
  • On a room thermostat, set the maximum values.
  • In the user settings, set the maximum temperature that you use in severe frosts. The burner always turns off when the indicators reach 5 ° C more than the installed. For example, at 75 degrees, the shutdown will happen after reaching 80 degrees.
  • Cool the coolant to 30 ° C.
  • Hold the Mode key on the panel. As soon as “0” appears on the display, set the value 35 by pressing “” and “.”.
  • Click Mode to confirm.
  • As soon as D lights up on the screen. 0, enter the number of the lines in the menu. Do this with the help of “” and “.” D.(room). To configure the maximum power of the burner, select D.53, minimum. D.52.
  • Use Mode to move to the choice of parameter. Change it “” “.”.
  • Installation receives automatic confirmation.
  • Return to the source menu. hold Mode.

During the regulation with the help of the panel, monitor the change in flame and increase the temperature.

For the Panther’s Panter, actions are different:

  • Click Mode for about 7 seconds.
  • Using keys 2 (see the picture on top), enter the code 35.
  • Confirm the input.
  • As soon as the left side of the screen appears.00, using buttons 2, enter the number.

Maximum and minimum temperature of the gas boiler: which is better?

It is worth making a reservation that an ordinary wooden house for two rooms with a total area of ​​40 m² was taken to calculate. The quality of the insulation is average, the boiler with a capacity of 24 kW works works. It is proposed that the rooms should warm up to 21 degrees of heat.

40 degrees

The most economically ineffective regime. Firstly, the boiler will lack rooms about a degree. Because of this, the pump and the burner will work constantly, which will lead not only to the overrun of the gas, but also to increased electrical consumption. Measurements show that electricity may need about 3 times more than in a mode of 70 degrees! Therefore, if there are problems with power supply or the boiler works from the generator, this mode should refrain.

In this mode, batteries begin to cool down literally a few hours. It is also worth noting that with high wear of the heating system, the high probability of condensate formation, which harms the boiler.

50 degrees

Typically, with such settings, the boiler shows the lowest gas consumption, however, the circular pump in this case works almost without stopping. Due to the high price of electricity, this mode is more expensive than the following.

Batteries cool much longer, the boiler completely warms up to the required temperatures.

60 degrees

Optimal settings for most boilers. At this temperature of the gas coolant, more than 50 degrees is required, but the pump works less often. The room is heated completely, the batteries cool for a long time, and the total costs are below other modes.

70 degrees

Electricity requires even less than 60 degrees, but much more gas is needed. Although at first glance it seems that such settings are more profitable, the danger lurks in another. With this operating mode, the battery will be offered to heat up, even with the boiler turned off. Thus, in the room, temperature surges are possible, which will negatively affect not only comfort, but also on the state of the entire heating system, in particular pipes.

80 degrees and above

Similar settings are not recommended. Firstly, such settings are needed in severe frosts if you live in the northern regions of the country. Secondly, due to the effects of high temperatures, the pipes quickly become unusable, and an unpleasant odor may also appear.

How to save when heating, and what temperature should be indoors?

According to regulatory requirements in residential premises, the air temperature should be in the range from 18 to 25 degrees of heat. Experiment with settings, switch modes, select a comfortable temperature for you.

Remember that at night the temperature is lower than during the day. In this case, the use of programmers who automatically regulate the operation of a gas boiler at temperature changes will be ideal. Thus, you will save without losing comfort.

If your house is connected to the gas line, then install the counter. So you can accurately control the fuel consumption and pay only for the spent volume, and not according to the norm.

Requirements for premises and air exchange

An important advantage of a private house, unlike city apartments, is the ability to allocate non.residential premises for installing heating equipment. The current regulatory documents provide a number of requirements for the size and arranges of such rooms. The main of them:

  • The total area of ​​4 m2 or more should provide the possibility of placing a boiler at a distance of 350 mm from the outer wall;
  • ceiling height of at least 2.5 meters;
  • floor level in the furnace not lower than the zero mark of the building;
  • The width of the front door is from 800 mm, while the sash should open out;
  • the mandatory presence of a glazed window, the area of ​​which is determined depending on the thermal performance of the gas boiler;
  • The lighting rate is set 0.03 l/m2;
  • The minimum cross.sectional area of ​​the air duct of the supply natural ventilation is 8 cm2 for each kW of the power of the heating unit.

When organizing air supply, it is necessary to take into account its amount used to burn gas and add three times the air exchange by volume of the room.

water, temperature, boiler

All walls and internal partitions should be built of non.combustible refractory materials with a fire resistance limit for at least 45 minutes. The layout of the room and the installation of ventilation ducts should not contribute to the spread of flame in case of fire.

The volume of free space not occupied by installed equipment is normalized depending on the power of the installed boilers:

Installation of a gas boiler in a private house with a total heat capacity of more than 200 kW is prohibited. In this case, the power of one unit should not exceed 100 kW.

The most economical mode of operation of the gas boiler

Forums have been overwhelmed by the topic for many years. how to make the boiler work, consuming less gas? It is necessary to understand the principle of operation of the gas boiler and, as mentioned earlier, it is necessary to track the rhythm of the burner.

Each time the burner is triggered, many resources are consumed. The more often it works in a day, the more disadvantage is. By putting a gas boiler at a temperature of 60 degrees, prevent constant ignition and accumulation of condensate.

boiler temperature. how to make your boiler more efficient.

Do not put low temperatures, especially if you often turn on hot water or heat the floor. In just one winter, save a lot of money, doing everything right. Follow the operating modes, delve into the frequency of inclusion and be interested in energy consumption.

When working at high temperatures in gas boilers, efficiency rises to maximum. Therefore, when you set the temperature below 60 degrees in the hope that you can save, the consumption on the contrary increases.

By turning on the temperature control mode by air (for this you need a thermostat), you can also save a good amount. Froze through the air more precisely than on the coolant.

The effectiveness of the proposed method

With relatively small cash costs, the installation of a water heater, expander and pump allows:

  • save up to 25 thousand. liters of water per year, if a family of four lives in the apartment,
  • use water of comfortable temperature even in case of simultaneous operation of several points of water fence,
  • reduce gas and electricity consumption,
  • extend the service life of a double.circuit boiler.

With forced circulation

Such a system is divided into two types:

The difference between them is quite large. The pipes are distinguished by the pipes, their number, sets of shut.off, regulating and controlling reinforcement.

According to SNiP 41-01-2003 (“heating, ventilation and air conditioning”), the maximum temperature of the coolant in these heating systems is:

The optimum temperature is from 85 ° C to 90 ° C (due to the fact that at 100 ° C, the water is already boiling. When this value is achieved, you have to use a special measures to stop boiling).

The dimensions of the heat given by the radiator depend on the installation site and the method of connecting pipes. Thermal return may decrease by 32% due to the unsuccessful location of the pipes.

The best option is a diagonal connection when hot water goes from above, and the return.below the opposite side. Thus, the radiators are checked in testing.

The most unsuccessful thing is when hot water goes from below, and cold from above on the same side.

Calculation of the optimum heating temperature

The most important thing is the most comfortable temperature for human existence 37 ° C.

When choosing a radiator, you need to calculate whether the thermal power of the device is enough to heat the room. There is a special formula for this:

  • where s is the area of ​​the room;
  • H is the height of the room;
  • 41. minimum power per 1 cubic meter m s;
  • 42. nominal thermal conductivity of one section by passport.

Keep in mind that the radiator set under the window in a deep niche will give almost 10% less heat. A decorative box will take 15-20%.

When you use a radiator to maintain the necessary air temperature in the room, you have two options: you can use small radiators and increase the temperature of the water in them (high.temperature heating) or set a large radiator, but there will not be such a high surface temperature (low.temperature heating).

With high.temperature heating, the radiators are very hot and you can get a burn if you touch it. In addition, at high temperature of the radiator, the decomposition of the dust that has settled on it, which will then be inhaled by people may begin.

When using low.temperature heating, the devices are slightly warm, but the room is still warm. In addition, this method is more economical and safe.

Cast iron radiators

The average heat of heat in a separate section of the radiator from this material is from 130 to 170 watts, due to thick walls and large mass of the device. Therefore, it takes a lot of time to warm up the room. Although there is a reverse plus in this. a greater inertia provides a long maintenance of heat in the radiator after turning off the boiler.

The temperature of the coolant in it is 85-90 ° C

Aluminum radiators

This material is light, easily heated and with good heat transfer from 170 to 210 watts/section. However, it is subjected to negative effects of other metals and can not be installed in every system.

The operating temperature of the coolant in the heating system with this radiator is 70 ° C

Steel radiators

The material has even less thermal conductivity. But by increasing the surface area with partitions and ribs, he warms still well. Heat output from 270 watts. 6.7 kW. However, this is the power of the entire radiator, and not of its separate segment. The final temperature depends on the dimensions of the heater and the number of ribs and plates in its structure.

The operating temperature of the coolant in the heating system with this radiator is also 70 ° C

Probably more profitable it is to install equipment with a combination of properties of aluminum and steel battery. bimetallic radiator. It will cost you more, but the life will be longer.

The advantage of such devices is obvious: if aluminum withstands the temperature of the coolant in the heating system only up to 110 ° C, then the bimetal is up to 130 ° C.

The heat on the contrary, worse than that of aluminum, but better than other radiators: from 150 to 190 watts.

Warm floor

Another way to create a comfortable temperature environment in the room. What are its advantages and disadvantages over ordinary radiators?

From the school course of physics, we know about the phenomenon of convection. Cold air strives down, and when it heats up, it rises up. Therefore, by the way, legs freeze. The warm floor changes everything. the air heated below is forced to rise up.

Such a coating has a greater heat (depends on the area of ​​the heating element).

The floor temperature is also spelled out in SNiP-E (“Construction Norms and Rules”).

In a house for permanent residence, it should not be more than 26 ° C.

In rooms for temporary stay of people up to 31 ° C.

Institutions where classes with children are underway, the temperature should not exceed 24 ° C.

The operating temperature of the coolant in the heating system of the warm floor is 45-50 ° C. Surface temperature on average 26-28 ° C

Dear Sirs! I purchased in the fall U, through dealers, convectors built into the windowsill. 3 pcs (one 3m, others 2 to 1.2m). Installed them in the windowsill of which the depth is 50 cm, the heating season began and it turned out that they did not even heat up. We have a town house 4 floors. I live on the fourth is supposed to be another 5th floor. There is a boiler. Summed with coal. I have a water heating in the floor. The floor is warm enough. But as for the convectors, they are slightly warm and accordingly do not cut off cold air. The temperature in the comb reaches a maximum of 51 degrees, and as your dealers explained to me, that this temperature is not enough for the convector, a minimum of 70 degrees, but unfortunately if our boiler is served 80 degrees, then it will be very hot in the lower floors. In this regard, I wanted to ask your opinion, which can be done in my case. Can get convectors and change them to electric, although the repair has already been made ? Then how much it will be more expensive when paying a check for electricity? It is possible to install an electric boiler on convectors although I have very little space in the boiler room and how much the check for electricity grows? can just install wall radiators? Understand me correctly, I was advised to put built.in convectors in the windowsill. Since the windowsill is deep. And I, in turn, refused wall radiators. At the moment, my convectors do not warm and there are no radiators that. Agree very disappointing.I write to you in the hope of an answer and to help. Thanks.
