How Much Does It Cost to Run a Hot and Cold Water Dispenser in Nova Scotia? (2026)
Water coolers keep a tank of water hot and another cold around the clock. The hot side is the bigger draw, and the pair typically uses 300 to 600 kWh a year, more than many refrigerators.
A typical hot and cold water dispenser (150 W) costs C$0.030 per hour, or about C$3.60 per month at 4 hours a day in Nova Scotia. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (100 W) | C$0.020 | C$0.080 | C$2.40 | C$29.20 |
| Typical (150 W) | C$0.030 | C$0.12 | C$3.60 | C$43.80 |
| High (500 W) | C$0.10 | C$0.40 | C$12.00 | C$146.00 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 4 h/day ≈ 219 kWh per year.
