The additional electricity cost added to a household that has an electric sauna can vary depending on several factors, including the type of sauna, its size, usage patterns, local electricity rates, and efficiency of the sauna unit. Here's a step-by-step approach to estimating this cost:
-
Determine Sauna Power Consumption:
- Find out the wattage (power rating) of your electric sauna. This information is typically provided in the sauna's specifications or user manual.
- For example, a typical electric sauna heater may range from 3,000 watts (3 kW) to 9,000 watts (9 kW) or more, depending on the sauna size and heating capacity.
-
Estimate Usage Duration:
- Decide how often and for how long you plan to use the sauna per session. Typical sauna sessions can range from 30 minutes to 1 hour.
- Determine the frequency of sauna use per week (e.g., 2 sessions per week).
-
Calculate Energy Consumption:
- Use the formula: Energy (kWh) = Power (kW) x Time (hours)
- For example, if your sauna heater is rated at 6 kW and you use it for 1 hour: Energy (kWh) = 6 kW x 1 hour = 6 kWh per session.
-
Estimate Monthly Energy Consumption:
- Multiply the energy consumption per session (in kWh) by the number of sessions per week and then by the number of weeks in a month.
- For example, if you use the sauna twice a week for 1 hour each session: Monthly energy consumption = 6 kWh/session x 2 sessions/week x 4 weeks = 48 kWh/month.
-
Calculate Additional Electricity Cost:
- Determine your local electricity rate per kWh (usually in cents or dollars).
- Multiply the monthly energy consumption (in kWh) by the electricity rate to estimate the additional electricity cost.
- For example, if your electricity rate is $0.12 per kWh: Additional cost = 48 kWh/month x $0.12/kWh = $5.76/month.
Keep in mind that this is a basic estimation. Actual electricity costs may vary based on specific usage patterns, local electricity rates, and any other factors affecting household electricity consumption, but as you can see, in general, adding a sauna to your home doesn't break the bank!
