Before choosing a heater, it is necessary to determine the necessary minimum heating power for a given room.

Formula for calculating the required heat output

V – volume of the room to be heated (W x L x H) q m³

ΔT – temperature increase required (°C)

K – thermal insulation coefficient

K=3,0-4,0 Simple building made of wood or corrugated sheet - Non-insulated

K=2,0-2,9 Simple structure, single layer of bricks, straight windows and roof - Poor insulation

K=1,0-1,9 Standard construction, double layer of bricks, few windows, standard closed roof - Medium insulation

K=0,6-0,9 Advanced construction, double insulated brick, few double windows, solid foundation, roof of well insulating materials - Good insulation

Example: heat output required

144 x 23 x 4 = 13 248 kcal/h

• 1 kW/h = 860 kcal/h
• 1 kcal/h = 3,97 Btu/h
• 1 kW/h = 3412 Btu/h
• 1 Btu/h = 0,252 kcal/h

Now you can choose the device that best suits your needs.
