What is a smart thermostatic tap (or smart thermostatic head)?

A smart thermostatic valve is an innovation in efficient home temperature control, offering users a higher level of convenience and energy savings. This advanced device replaces traditional radiator valves, allowing precise temperature regulation in every room.

Its operation is based on smart technology and connectivity to the local network or internet. Using a dedicated app on a smartphone or tablet, users can set and control individual temperatures for each room or zone. This allows comfort to be customised according to preferences and needs.

A key aspect of the smart thermostatic head’s operation is the built-in temperature sensor, which constantly measures room temperature. Based on these measurements, the thermostatic head automatically adjusts the flow of water to the radiator to maintain the desired temperature. This prevents overheating or underheating, helping to save energy.

Another notable feature is automatic programming or creating custom programs. For instance users can set heating programmes according to schedule or preference. This ensure a comfortable environment when needed and saving energy during periods of inactivity.
