How much electricity does your sauna heater consume per year? And how much does it actually cost you? Find out right here.
You might have already used our sauna heater size calculator and now want to find out about the heater’s costs. Please note, that even though this gets fairly advanced, it can still only get you an estimate. Every sauna build is different, and seasonal changes might affect it as well. There also might be differencies in energy efficiency between heaters.
We also created a comparison between an electric sauna vs. infrared, if that’s something you might be thinking about.
Sauna Power Consumption & Cost Calculator
Find out how many kWh your sauna sessions add up to — and what that costs
Time to bring the room up to temperature — runs at close to full power.
Once at temperature, the thermostat cycles the heater on and off — average draw drops well below the rated kW.
A heater doesn’t draw its full rated kW for the whole session — it runs hardest while bringing the room up to temperature, then cycles down to hold it. Adjust these if you know your heater’s real behavior; the defaults are a solid general estimate.
Enter your rate per kWh to see estimated cost. Leave blank to skip.
Do you also pay a regional electricity distribution fee / grid charge on top of your base price? If so, please also include that in your input amount.
Same routine, different heater sizes
