A hot tub drawing 3,000W and running 6 hours per day uses approximately 540 kWh per month. At Ontario rates, that costs about $55.62 per month. In winter, run time may increase to 10 or more hours per day to maintain temperature, pushing costs to $80 to $120 depending on your province and insulation quality.

Question 3

What is the most expensive appliance to run in Canada?

Accepted Answer

EV Level 2 chargers (7,200W) are typically the highest single energy consumer, costing $89 per month at Ontario rates for 4 hours daily use. Central air conditioning (3,500W) running 8 hours per day costs about $86 per month, and clothes dryers (5,000W) used 1 hour daily cost $15 to $24 per month.

Question 4

How much does air conditioning cost per month in Ontario?

Accepted Answer

A window AC unit (1,200W) running 8 hours per day costs approximately $29.66 per month. A central air conditioning system (3,500W) running 8 hours per day costs about $86.52 per month. These costs apply at Ontario average residential rate of 10.3 c/kWh. Using off-peak TOU or ULO rates can reduce these costs.

Question 5

Does a refrigerator use a lot of electricity?

Accepted Answer

Modern refrigerators are quite efficient. A typical model uses about 150W on average (the compressor cycles on and off). Running 24 hours a day, a fridge costs approximately $11.12 per month in Ontario and $8.10 per month in Quebec. Older models from the 1990s may use 2 to 3 times more energy.

Question 6

How do I reduce my appliance electricity costs?

Accepted Answer

Run high-draw appliances like dryers and dishwashers during off-peak hours (evenings and weekends on TOU, overnight on ULO). Use a programmable thermostat for space heaters. Switch to LED lighting. Ensure your fridge and freezer seals are tight. Consider replacing appliances over 15 years old with Energy Star certified models that use 25% to 50% less energy.
