Understanding these factors is the first step in optimizing the electricity consumption of your sauna. Being aware of your usage patterns, combined with efficient practices, can lead to both a fulfilling sauna experience and manageable electricity bills. In the following sections, we'll delve into the specifics of calculating electricity consumption and its cost implications.

Calculating Electricity Consumption

When determining the electricity consumption of a sauna, it's essential to familiarize yourself with a few key terms and how they relate to energy usage:

1. Watts (W) and Kilowatts (kW):

  • Definition: Watts measure the rate of energy consumption. Sauna heaters often come with a wattage rating, indicating their maximum power consumption.

  • Conversion: 1 kilowatt (kW) is equal to 1,000 watts. For instance, if a sauna heater has a rating of 2,500 watts, it operates at 2.5 kW.

2. Kilowatt-Hours (kWh):

  • Definition: This is the unit of energy most commonly used to measure electricity consumption. It represents the amount of energy consumed when running a 1 kW appliance for one hour.

  • Example: If you use a 2.5 kW infrared sauna for 1 hour, it will consume 2.5 kWh of electricity.

3. Average Wattage of Infrared Saunas:

  • Most infrared saunas on the market have a power rating between 1,000 and 3,000 watts, with some larger models consuming even more. Always check the manufacturer's specifications for accurate details. At 1Love, our saunas have a focus on reducing energy consumption. For even our largest models using a 1200W power supply, they're engineered to not be drawing full power when necessary so they use significantly less power than you would assume.

Cost Implications

Knowing the electricity consumption of your sauna is only half the story. To fully grasp its impact on your wallet, you need to understand the cost implications:

1. Average Cost of Electricity:

  • The price per kWh can vary significantly depending on your location, provider, and current energy market trends.

  • As of the last update, the U.S. national average hovered around $0.13 per kWh. However, this figure fluctuates, so it's essential to check your local utility rates.

2. Estimating Monthly Costs:

  • Formula: Monthly Cost=Electricity Consumption (kWh) per session×Number of sessions per month×Cost per kWh

  • Example: If you use a 2.5 kW sauna for 1 hour every day, and the cost of electricity is $0.13 per kWh, your monthly cost would be: 2.5 × 30 × 0.13 = $97.50

  • Luckily, our far infrared saunas don't nearly use this amount of electricity, but many cabin-style saunas do.

3. Tips for Managing Costs:

  • Optimize the duration and frequency of your sauna sessions.

  • Use the sauna during off-peak hours if your utility company offers variable pricing.

  • Ensure the sauna is well-insulated to reduce heat loss and, consequently, energy consumption.
