VI-WATT turns everyday water heaters into smart thermal batteries, unlocking grid flexibility, CO₂ reduction, and multi-billion-euro savings across Europe.
Scalable, software-defined, and pilot-ready — VI-WATT connects households, utilities, and the EU’s clean-energy goals.
A new level of energy saving
Control not just consumption - orchestrate flexibility
Dynamic Power Modulation
Real-time control of heater power (0–100%) turns ordinary devices into responsive thermal batteries
Grid & Utility Integration
Synchronize with DSO/TSO signals to absorb renewables and reduce peak demand
CO₂ & ESG Impact
Participate in flexibility markets, track CO₂ savings, and unlock carbon credit potential
70%
Water heating represents up to 70% of household electricity use
Energy tariffs and peak penalties continue to rise annually
Every kWh of wasted heat is lost flexibility and lost revenue
Utility & Platform Integration
Seamless API connectivity with DSOs/TSOs and energy platforms.
