No, you typically do not need to have all the zones of your underfloor heating system on simultaneously. Underfloor heating systems are often divided into different zones, allowing you to control and heat specific areas independently. This zoning capability enables you to adjust the heating in different rooms or sections of your home according to your preferences and usage patterns.
By using a thermostat or control panel that manages the different zones, you can activate or deactivate specific areas as needed. For example, you might want to heat the living room during the day while keeping the bedroom or other areas turned off to save energy.
Controlling the heating zones individually offers flexibility and efficiency, allowing you to tailor the heating system to match your comfort requirements and save on energy costs by only heating the spaces that are in use.
