Calculating radiator or central heating core length is a subject that everyone who is considering installing a heating boiler or combi boiler should have some knowledge of. A small calculation about the radiator core length calculation will ensure that the installation you will make and the heating boiler you will choose are selected correctly.

 

Basic Information for Calculating Heating Core Length

 

Practical radiator core length calculation: 22 types of panel radiators, 1 meter long and 60 cm high, heat an average of 9-12 m² area. When calculating practical honeycomb length, we can take this figure as 1 meter honeycomb for an average area of ​​10m².

 

How many calories does a panel radiator give off? A 22 type honeycomb with a length of 1 meter and a height of 60 cm gives 1800 kCal/h of heat. The heat given by the heater cores may vary according to the models.

 

Radiators selection with cubic meter calculation: Heating can be provided with an average of 45 kCal/h energy consumption per 1m³.

 

1 meter Radiators can heat the indoor area between 9-12m². The variability of this data is due to factors such as the location of each house, its north-south façade, whether there is a mezzanine or not. In addition, the calorie given varies according to the selected panel radiator brand and model. You can use the following calculations when determining the heater core prices.

 

The height of the apartments is generally accepted as 2.70 m. In high ceilings, volume calculation will give more accurate results instead of practical calculations.

How to Select a Heating Core with Practical Heat Loss Calculation?

 

When calculating heat loss, first of all, the sitting area should be calculated.

per cubic meter; One of the values ​​of 1st zone:30 kCal/h, 2nd zone: 45 kCal/h, 3rd zone: 60 kCal/h, 4th zone: 70 kCal/h is selected according to the zone condition of the flat where heat loss will be made.

If the area to be heated is BASEMENT, TERRACE or ROOF floor, 15 kCal is added to the values ​​selected above.

For example;

What is the heat loss of a 6×4 m² hall on the 2nd floor of a 4-storey building in Ankara (2nd district)? (Let's take the floor height as 3.)

 

Area: 6×4=24m²

2nd region value: 45kcal h=3m

Heat loss: 24x3x45=3240 kCal

 

Let's assume that Emtaş brand steel panel radiator will be used for the selection of radiators for the same area;

 

An Emtaş brand Type 22 PKKP 600x1000 radiator has a heating value of 1800 kCal/h for 70/50 °C.

3240/1800=1.8m. Well; TYPE 22 PKKP 600x1800 mm radiator is selected.

 

Heating Core (panel radiator) Selection with Practical Calculation Formula:

 

Ru=Radiator Length(m)

Oh=The Volume of the Room(m³)

Od=The Condition of the Room (If it is facing north: 60, in other directions 40 is taken.)

Rk=Radiator Calories (2300 if PKKP 600, 1850 if PKKP 500)

Ru=(Oh*Od)/Rk

 

For example;

If the room faces north and is 3 meters by 4 meters long, 3 meters high, and suitable for the use of 600 radiators;

 

Oh=3*4*3=36 m³

Ru=(Oh*Od)/Rk

Ru=36*60/2300=0.93, that is, 1 meter of radiator is sufficient.

 

*The calorie of the radiator may vary depending on the brand.

 

In general, in the most practical way, a 1 m long 60 cm high 22 type panel radiator heats 10 m² of space. You can evaluate the rooms, hall and living room of your house according to this calculation. Whatever the result is, you can provide a more efficient heating by calculating 20 cm long heater core length.
