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.
The compressor for cold water surges briefly at startup, while the hot water heating element draws stable, consistent wattage.
