Almost any home can not do without heating radiators. They can be: cast iron, steel aluminum, bimetal. Their choice depends on several factors: the technical feasibility of the heating system, the quality of the coolant, as well as the individual choice of the owner, taking into account his idea of the quality of this product. The main purpose of the heating radiator is to provide a comfortable microclimate in a heated room.
Nowadays, bimetallic, cast-iron, steel heating radiators are in great demand, and almost every buyer who wants to replace or install heating radiators on their own faces the question of the number (size) of radiators. Let's take a closer look at this issue.
Firstwhat we need to know is that when calculating the type of radiator does not matter whether it is steel, aluminum, cast iron or bimetal. We are interested in only one indicator - this is the power of the radiator. Each manufacturer must indicate it. Last resort, knowing modelYou will always find this data on the Internet. Take note of the fact that some manufacturers may exaggerate this figure.
Second, we need to know the area of the heated room. It is important to know that the calculation should not be done for the total area of the apartment (house), but for each room separately.
Third, the formula for calculating the power of the radiator is wonderfully simple, and it can be used by any average person. According to SNiPu per 1 square. m of premises with an average ceiling height (2.7 m) accounts for 100 watts of thermal power. Therefore:
K = S x 100 / P
K - number of sections
S - area
R - power of the radiator.
: calculation of the radiator power for a room of 25 square meters with a standard ceiling height of 2.7 m. The average power of one section is 180 watts. (example, the power of the Mirado bimetal radiator is 185 W)
K = 25 x 100/180
K = 13.8 pcs
We round to 14, that is, 14 sections are needed. This calculation can easily be attributed to sectional radiators, as well as cast-iron (60 cm) from the calculation of 1 rib = 1 section.
:
The number of radiators depends on the number of window openings in the room.
If the room is angular or end, or there are frequent failures in the heating system, namely a decrease in the temperature of the coolant, add 20% to any indicator obtained (whether it is the number of sections or the capacity of the radiator).
