Calculation Tables for Installations
Easily Calculate Your Heating Requirements
We provide you with a straightforward method to calculate the necessary wattage per square metre for heating each room with an approximate height of 2.5 meters.
Step-by-Step Guide
To perform your heating calculation, follow these simple steps:
-
Identify your location on the climatic map provided and note the letter that corresponds to your area.
-
Locate the relevant table based on the type of heater you wish to use and the insulation level of your home (guidance on identifying insulation type is available later).
-
Based on the number of external walls and the position of the room, find the intersection point with the climatic zone determined in step one.
-
Multiply the value obtained from the table by the area of the room you wish to heat. The resulting value will represent the heating power required for that room.
Identifying the Type of Insulation
Properties are classified based on their insulation levels as follows:
-
Low Insulation: These homes lack thermal insulation in their external walls and have single-glazed windows.
-
Medium Insulation: Older properties that do not have insulation in their external walls but feature double-glazed windows with thermal break are considered to have medium insulation.
-
High Insulation: Newly built homes equipped with thermal insulation in their external walls and double-glazed windows with thermal break are classified as having high insulation.
Important Notes
-
When calculating heating requirements for bedrooms, the resulting power can be reduced by 15%.
-
For kitchens, the heating requirements calculation can be reduced by 20% of the resulting power.
-
If the calculation is for heating in detached homes in non-urban areas, the final result should be increased by 20%.
