Every home owner in the heating device is faced with important issues.What kind of sink to choose?How to calculate the number of sections of the radiator?If you build a house for professional staff, they will help to make the calculations, the distribution of heating duct in the building was rational.However, this procedure can be carried out independently.Necessary for this formula can be found below in the article.
Types radiators
Today there are these types of batteries for heating: bimetal, steel, aluminum and cast iron.Also, the radiators are divided into panel, sectional, convector, tubular and design radiators.Their choice depends on the coolant, the technical capabilities of the heating system and the financial ability of the owner of the house.How to calculate the number of sections of the radiator to the room?It does not depend on the type of heating the battery.This takes into account only one indicator - the radiator power.
Payment Methods
to the heating system in the room worked efficiently and in the winter it was warm and comfortable, you need to carefully calculate the number of sections of the radiator.For this purpose, such methods of calculations:
- Standard - is based on the provisions of SNIP, according to which the heating capacity of 1m2 will require 100 watts.The calculation is performed using the formula: S x 100 / P, where P - power branch, S - area of the selected room.
- exemplary - for heating 1.8 m2 apartment at ceiling height of 2.5 m, will need a radiator section.
- volumetric methods - heating power 41 W is taken to 1m3.Taken into account the width, height and length of the room.
as necessary for the whole house radiators
How to calculate the number of sections on the radiator room apartment or house?It performs calculations for each room separately.According to the standard, the thermal power per 1m3 volume of the space that has one door, window and exterior wall, is considered to be 41 watts.
If the house or apartment, "cold", with thin walls have a lot of windows, the house is not insulated the attic, and the apartment is on the ground or top floor, for their heating must be 47 watts per 1m3 instead of 41 watts.For a house built of modern materials with different insulation for walls, floors, ceilings, has plastic windows.You can take 30 watts.
to replace cast iron radiators, there is the easiest method of calculation: the number should be multiplied by 150 W, the resulting number - Power of new devices.Buying aluminum or bi-metal batteries to replace, the calculation is carried out in the ratio one to one edge of the iron aluminum.
Rules for calculating the number of branches
How to calculate the number of sections of the radiator to the room?To do this, follow these rules:
- Increased capacity radiator takes place: if the room has one end and the window - 20%;two windows - 30%;windows facing north, also require an increase by 10%;battery installation under the window - 5%;closing heater decorative screen - by 15%.
- power required for heating can be calculated by multiplying the size of the floor area (in m2) of 100 watts.
Tips for installing radiators
The passport is indicated by the manufacturer for the products of specific power, which makes it possible to calculate the proper number of sections.Do not forget that heat affects the power separate section, rather than the size of the radiator.Therefore, the establishment of accommodation and in the room a few small appliances more efficient than establishing a single large.The incoming heat from all sides evenly him warm.
Calculating the number of branches of bimetallic battery
How reliably calculate the number of sections of bimetallic radiator for a room?It requires such raw data:
- Dimensions of the room and the number of windows in it.
- locate a specific room.
- presence of unclosed openings, arches and doors.
- heat capacity of each section labeled by the manufacturer in the passport.
Stages of computation
How to calculate the number of sections of the radiator, if all the necessary data is recorded?To do this, define the area, the number of the derivatives meters width and height of the room.Using the formula S = L x W, calculated joint area of the adjacent rooms, if they have unclosed openings or arches.
further conduct calculation of the total thermal power of the battery (P = S x 100) using a power of 100 W for heating one m2.Then calculate the proper number of sections (n = P / Pc) by dividing the total heat output to heat one section indicated in the passport.
Depending on the location of the calculation of the required number of rooms branches bimetallic device made taking into account the correction factors: 1.3 - for a corner;using a coefficient of 1.1 - for the first and last floor;1.2 - used for the two windows;1.5 - three or more windows.
Example:
Performing calculations in the end sections of the battery room, located on the first floor and has two windows.Dimensions of the room 5 x 5 m. Heat transfer of one section of 190 watts.
- room area is calculated: S = 5 x 5 = 25 m2.
- expect thermal power in general: P = 25 x 100 = 2500 watts.
- perform calculations required sections: n = 2500/190 = 13.6.Rounded up, we get 14. Take into account the correction factors n = 14 x 1.3 x 1.2 x 1.1 = 24.024.
- Section is divided into two batteries and set them under the windows.
We hope that the information stated in the article will tell you how to calculate the number of sections of the radiator for home.To do this, use the formulas and perform relatively accurate calculation.It is important to select the power section, which is suitable for your heating system.If
independently calculate the required number of batteries for homes you can not afford, it is best to seek professional help.They will perform a competent settlement, taking into account all the factors affecting the performance of the installed heaters, which provide heat in the house during the cold period.
