3 Ways to Cut Your Hot/Cold Water Dispenser Energy Bill

  • 🌱

    Turn off the hot water function at night and when away — the heating element maintaining temperature is the biggest energy draw.

  • 💡

    Use the energy-saving night mode if available, which reduces or turns off heating/cooling during set hours.

  • Place it away from direct sunlight and heat sources to reduce the load on the cooling compressor.
