How Much Does It Cost to Run a Aquarium (Heater, Filter, Light) in Newfoundland and Labrador? (2026)
An aquarium's cost is mostly the heater, which cycles on and off to hold temperature, plus a filter pump running all day and lights on for 8 to 12 hours. A 100 litre tropical tank uses roughly 30 to 60 kWh a month.
A typical aquarium (heater, filter, light) (80 W) costs C$0.013 per hour, or about C$4.61 per month at 12 hours a day in Newfoundland and Labrador. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (30 W) | C$0.005 | C$0.058 | C$1.73 | C$21.02 |
| Typical (80 W) | C$0.013 | C$0.15 | C$4.61 | C$56.06 |
| High (300 W) | C$0.048 | C$0.58 | C$17.28 | C$210.24 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 12 h/day ≈ 350 kWh per year.
One day of an aquarium (heater, filter, light) (1.9 kWh) is the same electricity as
- 11km in an electric car
- 19hours of TV
- 43hours of a laptop
- 213hours of an LED bulb
In Newfoundland and Labrador, with electricity at C$0.16 per kWh (source: Hydro-Québec 2025 comparison, 2025-04), a typical aquarium (heater, filter, light) costs C$0.013 per hour and about C$56.06 per year at 12 hours a day. That is about 14% more than the national average for Canada (C$4.03 per month), because electricity in Newfoundland and Labrador costs C$0.16 per kWh against C$0.14 nationally. Each C$1.00 of electricity buys roughly 78.1 hours of use.
How to lower the cost of running a aquarium (heater, filter, light)
- Put the tank away from windows and drafts so the heater runs less.
- Cover the tank. An open top loses heat through evaporation.
- Use LED lighting on a timer for 8 hours rather than 12.
