Calculating the number of radiator sections - Not all residents of homes can boast that they have heat in the apartment. Quite often not heat radiators for sale in sufficient quantities so you have to freeze. Out of this situation : I have to replace old radiators with new ones.
In most old houses are cast iron radiators, which are durable . They can serve you for years, but since rust in the radiator heating system grind for many years , their heat output decreased significantly . Besides CHP not always heats water sufficiently , which directly affects the temperature inside the apartment. And if so , then it’s time to replace radiators with new ones, so you no longer have to freeze .
Today the market is the most popular are bimetallic and aluminum radiators . They have high heat , and thanks to the epoxy coating the inside of the radiator sections protected from oxidation.
How to calculate the number of sections of the radiator When installing the radiator is very important to calculate the number of sections . Requires it to maintain a comfortable room temperature for you , you do not have any freeze or sweat out the heat.
When calculating the radiator sections do not take into account of what exactly the material it is made . Whether you’ve got a steel bimetal or aluminum radiator , always repelled from one section of the power and area of the room you want to heat .
Power radiator sections are always specified in its technical characteristics . On average, it is about 180 watts. Note that output sections of different manufacturers to be more or less, so the calculation should take into account these changes .
To calculate the required number of sections need to know the area of each room, which will change the radiator . Suppose we want to change the radiator in a room of 18 square meters. m
The third value that we need - is the thermal power needed to heat one square meter of space . For rooms with high ceilings 2.5-2.65 m , this value is 100 watts.
From these data , one can calculate the required number of sections . To do this, multiply the area of the room to the desired heat output and power are divided into one section : 18 x 100/180 = 10
The result will be a necessary number of sections for heating one room . In this case the sections 10 . If you got a non-integer , then it is rounded toward greater . When calculating the number of sections for the kitchen radiator resulting number can safely be rounded to the smallest.
When calculating the number of sections should also take into account some of the nuances of the characteristics of the radiator and space. For example, this calculation is valid for a room with a door and window . If there is no room in front of a glazed loggia or whether it is a corner , then to the resulting number of partitions you want to add another 20%. In the rooms with new windows from the number of sections obtained safely subtract 15%. In the case of the battery inserted in the same niche or screen heat losses amount to 15-20%.
As you can see , to calculate the required number of sections radiators per room is not so difficult as it might seem . And if you are not confident in their calculations , it does not hurt to consult a specialist .
