To calculate the number of radiators in an apartment or in a private house, you will need to first pick up radiators. At the same time, the heated area is measured and other reference values taken into account. All temperature norms are indicated in the relevant SNiP.But it is not necessary to study all this, because a special program will save you a lot of difficulties.

power radiator Calculation: calculator and battery material
radiators calculation begins with the selection of heating devices themselves. For batteries on a battery this is not necessary, since the system is electronic, but for standard heating it is necessary to use a formula or a calculator. Distinguish the battery behind the fabrication material. Each option has its own power. Much depends on the required number of sections and dimensions of heating devices.
Types of radiators:
 Bimetallic;
 Aluminum;
 Steel;
 Cast iron.
Two types of metal are used for bimetallic radiators: aluminum and steel. The inner base is made of solid steel. The outer side is made of aluminum. It provides a good increase in heat transfer of the device. The result is a reliable system with good power. The heat transfer affects the interaxle interval and a certain model of the radiator.
The power of the Rifar radiators is 204 W at the interaxial interval of 50 cm. Other manufacturers provide products of lower productivity.
For an aluminum radiator, the thermal power is similar to that of bimetallic devices. Usually this index at an interaxial distance of 50 cm is 180190 W.More expensive devices have a power of up to 210 watts.
Aluminum is often used, organizing individual heating in a private house. The design of the devices is quite simple, but the devices differ excellent heat transfer. To hydraulic shock such radiators are not stable, therefore they can not be used for central heating.
When calculating the power of a bimetallic and aluminum radiator, the index of one section is taken into account, since the devices have a monolithic design. For steel compositions, the calculation is performed for the entire battery at certain sizes. The choice of such devices should be carried out taking into account their ranks.
Measurement of heat transfer of cast iron radiators varies from 120 to 150 W.In some cases, the power can reach 180 watts. Cast iron is resistant to corrosion and can work at a pressure of 10 bar. They can be used in all buildings.
Cast iron consoles:
 Heavy  70 kg weigh 10 sections with a distance of 50 cm;
 Complicated installation due to gravity;
 Long warms up and uses more heat.
When choosing which battery to buy, consider the power of one section. So determine the device with the necessary number of compartments. With an interaxial distance of 50 cm, the design capacity is 175 W.And at a distance of 30 cm the figure is measured as 120 watts.
Calculator for calculation of heating radiators by area
Calculator registers by area is the most simple way to determine the required number of radiators per 1m2.Calculations are made on the basis of the norms of the produced capacity. There are 2 basic rules of norms that take into account the climatic features of the region.
Basic rules:
 For moderate climates the required power is 60100 W;
 For northern regions the norm is 150200 W.
Many are wondering why the standards have such a large range. But the power is chosen based on the initial parameters of the house. Concrete structures require maximum power. Brick  medium, insulated  low.
All norms are taken into account with an average maximum height of the chalk 2.7 m.
To calculate the sections, it is necessary to multiply the area by the norm and divide by the heat transfer of one section. Depending on the model, the heatsink takes into account the power of one section. This information can be found in the technical data. Everything is simple enough and does not present any special difficulties.
Calculator for simple calculation of heating batteries for area
Calculator is an effective calculation option. For a room of 10 m square meters, 1 kW( 1000 W) is required. But this is provided that the room is not a corner and installed double glazed windows. To find the number of edges of panel instruments, it is necessary to divide the required power into the heat transfer of one section.
This takes into account the height of the ceilings. If they are above 3.5 m, then it will be necessary to increase the number of sections by one. And if the room is corner, then we add plus one compartment.
Take thermal power reserve into account. This is 1020% of the calculated index. This is necessary in case of severe cold.
The heat transfer of the sections is specified in the technical data. For aluminum and bimetal batteries, the power of one section is taken into account. For castiron appliances take as the basis heat transfer of the entire radiator.
Calculator for the exact calculation of the number of heating radiator sections
A simple calculation does not take into account many factors. As a result, the curved data is obtained. Then some rooms remain cold, the second  too hot. The temperature can be controlled with the help of stop valves, but it is better to count everything in advance in advance in order to use the required amount of materials.
For exact calculation, use reducing and increasing thermal coefficients. First you should pay attention to the windows. For single glazing, a factor of 1.7 is used. Double windows do not need a factor. For triple the indicator is 0.85.
Next, take into account the brickwork. For a wall in two bricks or with a sealant, a coefficient of 1. With a thermal insulation, 0.85 is used, in the absence of 1.27.
If the windows are single, and there is no thermal insulation, the heat losses will be quite large.
The calculation takes into account the ratio of floor area and windows. The ideal ratio is 30%.Then the coefficient 1 is applied. As the ratio is increased by 10%, the coefficient rises by 0.1.
Coefficients for different ceiling heights:
 If the ceiling is below 2.7 m, the coefficient is not needed;
 For indicators from 2.7 to 3.5 m, a factor of 1.1 is used;
 When the height is 3.54.5 m, a factor of 1.2 is required.
In the presence of lofts or upper floors, also applies certain coefficients. With a warm attic apply a rate of 0.9, a living room  0.8.For unheated attics, take 1.
Volume calculator for calculating heat for room heating
Similar calculations are used for rooms that are too high or too low. In this case, calculate the volume of the room. So on 1 m cube you need 51 watts of battery power. The calculation formula has the following form: A = B * 41
Decoding of the formula:
 And  how many sections are needed;
 В  room volume.
To find the volume, multiply the length by height and width. If the battery is divided into sections, the total demand is divided by the power of the whole battery. Obtained calculations are generally rounded up, as companies often increase the capacity of their equipment.
How to calculate the number of radiator sections per room:
errorsThe thermal power behind the formulas is calculated taking into account the ideal conditions. Ideally, the temperature of the coolant at the inlet is 90 degrees, and at the outlet  70. If the house maintain a temperature of 20 degrees, then the warm head of the system will be 70 degrees. But at the same time one of the indicators will necessarily differ.
professionals. First, you need to calculate the temperature head of the system. We take the initial data: the temperature at the inlet and outlet, in the room. Next, we define the delta of the system: we need to calculate the arithmetic mean between the input and output parameters, then take away the temperature in the room.
The resulting delta should be found in the conversion table and multiply the power by this factor. As a result, gets the power of one section. The table consists of only two bars: delta and coefficient. The indicator is obtained in watts. This power is used when calculating the number of batteries.
Features of calculating heating
It is often claimed that for 1 meter square is enough 100 watts. But these indicators are superficial. They do not take into account many factors that are worth knowing about.
Required data for calculation:
 Room area.
 Number of external walls. They cool the rooms.
 Sides of the world. It is important that the sun or shaded is the side.
 Winter wind rose. Where there is enough windmill in winter, the room will be cold. All data are taken into account by the calculator.
 Climate of the region  minimum temperatures. It is enough to take the average indicators.
 Wall masonry  how many bricks were used, is there any insulation.
 Windows. Take into account their area, insulation, type.
 Number of doors. It is worth remembering that they take away heat and bring cold.
 Battery connection diagram.
In addition, always takes into account the power of one section of the radiator. Thanks to this you can find out how many radiators to hang in one line. The calculator greatly simplifies the calculations, since many data are unchanged.

The number of edges per room is easily determined with the help of a calculator. To correctly calculate everything, you need to know how many squares are heated and some features of a private house or apartment. You can do everything according to the standard. On the basis of this, the selection of devices for heating is simplified. At the same time it is possible to deduce the necessary quantity of kilowatts and independently for the formula.
