How Much Does It Cost to Run a Electric Water Heater in Saskatchewan? (2026)
A tank water heater is often the single largest electricity user in a home without electric heating. The element only runs a few hours a day, but at 4,000 watts or more those hours add up fast.
A typical electric water heater (4,000 W) costs C$0.72 per hour, or about C$64.80 per month at 3 hours a day in Saskatchewan. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (3,000 W) | C$0.54 | C$1.62 | C$48.60 | C$591.30 |
| Typical (4,000 W) | C$0.72 | C$2.16 | C$64.80 | C$788.40 |
| High (5,500 W) | C$0.99 | C$2.97 | C$89.10 | C$1,084 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 3 h/day ≈ 4,380 kWh per year.
One hour of an electric water heater (4.0 kWh) is the same electricity as
- 22km in an electric car
- 40hours of TV
- 89hours of a laptop
- 444hours of an LED bulb
In Saskatchewan, with electricity at C$0.18 per kWh (source: Hydro-Québec 2025 comparison, 2025-04), a typical electric water heater costs C$0.72 per hour and about C$788.40 per year at 3 hours a day. That is about 29% more than the national average for Canada (C$50.40 per month), because electricity in Saskatchewan costs C$0.18 per kWh against C$0.14 nationally. Each C$1.00 of electricity buys roughly 1.4 hours of use.
How to lower the cost of running a electric water heater
- Set the thermostat to 120 F (49 C). Factory settings are often 140 F.
- Insulate the tank and the first few feet of hot water pipe.
- Fix dripping hot taps. A slow drip can waste hundreds of litres of heated water a month.
- A heat pump water heater uses about a third of the electricity of a resistive tank.
Frequently asked questions
How many hours a day does a water heater run?
Typically 2 to 4 hours of element time, depending on household size and shower habits.
Is a tankless water heater cheaper to run?
It avoids standby losses, saving 10 to 30 percent, but electric tankless units need very high amperage.
Should I turn off my water heater at night?
A timer helps if you have time-of-use rates. Otherwise the savings are small because a well-insulated tank loses little heat overnight.
