How Much Does It Cost to Run an Electric Sauna?
Thinking of getting a sauna but worried about the cost to keep it running? You’re not alone—many people imagine their electricity bill skyrocketing with a big, powerful heater inside. But don’t sweat it (pun intended)! Let’s break down the numbers and see just how much it really costs to use your sauna.
Key Assumptions
For this example, we’ll base our calculations on the following:
- Heater Power: 9 kW
- Usage Frequency: 3 sessions per week
- Session Duration: 1 hour
- Heat-Up Time: 1 hour
- Electricity Rate: $0.165 per kWh
Step 1: Calculate Energy Consumption per Session
Each sauna session involves:
- Heat-Up Phase: Heater runs at full power (9 kW) for 1 hour.
- Maintain Temperature Phase: Heater operates at half power (4.5 kW) for 1 hour.
Total electricity used per session:
9 kWh (heat-up) + 4.5 kWh (maintain) = 12.5 kWh
Step 2: Calculate Monthly Energy Usage
With three sessions per week, there are approximately 12 sessions per month:
12.5 kWh/session × 12 sessions = 150 kWh/month
Step 3: Calculate Monthly Cost
Now, to find out how much you’re really paying, multiply your monthly energy usage by the electricity rate:
150 kWh × $0.165/kWh = $24.75/month
The Bottom Line
So, there you have it! Running an electric sauna with a 9 kW heater, three times a week, costs about $24.75 per month. Not bad for a stress-relieving, sweat-inducing experience that you can enjoy regularly!
Think about it: For less than the cost of a few fancy lattes, you get to enjoy a personal wellness retreat in your own home. Pretty sweet, right? And if you’re looking for ways to save even more, consider a sauna with better insulation or a big sign on the sauna door: "PLEASE CLOSE THE DOOR".
