Thermostatic radiator valves (TRV)

They automatically modulate hot water flow based on each room's temperature. No more overheated or underheated rooms: every radiator works at the right level.

Smart valves add remote control and automation: schedules, away modes, abnormal ventilation alerts and consumption monitoring from your smartphone.

Control via app (iOS / Android) from anywhere
Time schedules and comfort / eco / away modes
Alerts for open windows or unusual temperature drops
History and tracking to optimise heating over time
Possible integration with voice assistants or smart home hubs (depending on brand)
