Heating curve (definition)

Heating curve (sometimes called a heating curve) is a graphical representation of the relationship between the outside air temperature and the required supply temperature of the heating medium in the heating system. It is used in weather-dependent heating systems for automatic regulation of the coolant temperature, ensuring more efficient energy consumption and comfort in the premises.

Heating curve and its characteristics:

• Temperature dependence: The heating curve shows how the supply temperature should change depending on the outside temperature. For example, when the outside temperature decreases, the supply temperature of the coolant increases, and vice versa.
• Adjustment: The heating curve parameters can be adjusted depending on the building characteristics, climate conditions and user preferences. This allows the heating system to be adapted to specific operating conditions.
• Energy saving: Correctly setting the heating curve helps to avoid overheating of the premises and reduces fuel consumption, making the system more economical.

Calculation in heating systems:

The calculated characteristic in the form of a graph is used in heating systems with automatic control, for example, in boilers with weather-dependent automation. It is especially relevant for systems with radiator or floor heating, where precise temperature control is required to maintain a comfortable microclimate.
