What is a weather compensated heat curve?
A weather-compensated heating curve (often called weather compensation) is an intelligent feature found in modern heat pump systems. It automatically adjusts the temperature of the heating water based on the outside air temperature, raising it as it gets colder, and lowering it as it warms up. This ensures your home remains consistently comfortable while maximising energy efficiency and reducing costs.
How It Works
Traditional heating systems use a fixed water temperature regardless of weather, even when it's mild outside. However, weather compensation continuously adapts the flow temperature:
Colder outdoor temperatures → higher flow temperature to meet heat demand
Warmer outdoor temperatures → lower flow temperature to avoid overheating and wasted energy.
This responsive adjustment helps maintain a comfortable home and improves system efficiency.
Benefits of a Weather-Compensated Heating Curve
Energy Efficiency
Delivers only the heat needed for current conditions—minimising wasted energy.
Lower Heating Costs
By tailoring output to demand, running costs drop.
Consistent Comfort
Reduces temperature fluctuations, preventing under- or over heating.
Reduced Cycling & Wear
Gradual modulation means systems run steadier, reducing wear and tear.
