The Sunamp Solution

Sunamp thermal batteries use advanced Phase Change Material (PCM) technology to solve these challenges.

  • High Density

    Stores 4x more energy than water in the same volume.

  • Instant Hot Water

    Delivers high-flow hot water on demand.

  • Grid Balancing

    Enables "Peak Shaving" by storing cheap/green energy for later use.

  • Zero Emissions

    Works seamlessly with heat pumps, solar, and wind.

  • Long Life

    Material tested to 43,000 cycles without degradation.
