The Vaughn VG-MP Grid-Enabled Featherweight Electric Water Heater brings utility-ready functionality in a lightweight, easy-to-install package. When paired with a grid-interactive control, a V-Grid electric thermal storage (ETS) water heater acts as a thermal battery. It can respond to price signals (LMP), work better with renewable energy sources, and help stabilize the grid. Its seamless thermoplastic tank resists corrosion and elevated temperatures without needing a sacrificial anode. The grid-enabled thermostat supports CTA-2045, Open ADR, WiFi, cellular, and BACnet for flexible integration with demand response programs.
