Operating a sauna heater can incur costs that depend mainly on electricity consumption. To get an idea of the operating costs of a sauna heater, various factors must be taken into account. First of all, the power of the heater is crucial. A sauna heater with a higher output (expressed in kilowatts, kW) consumes more electricity. Take, for example, a sauna heater with an output of 8 kW. The duration of use also plays an important role in calculating the costs. For example, if you operate your sauna for two hours, this means that your 8 kW heater will consume 16 kWh of electricity during this time (8 kW * 2 hours = 16 kWh).
The electricity price per kilowatt hour (kWh) is the next factor you should consider. This can vary depending on where you live and your electricity provider. In Germany, the average electricity price for private households was around €0.30 per kWh at the end of 2021. However, let's assume a price of €0.35 per kWh for this calculation.
To calculate the cost per use, simply multiply the energy consumed (in kWh) by the price per kWh. In our example, this would be 16 kWh * 0.35 €/kWh = 5.60 €.
So if you use your sauna once a week, the monthly costs are 4 weeks * 5,60 € = 22,40 €.
However, it is important to note that this is only a rough estimate. The actual cost can vary depending on how often and how long you use your sauna, what temperature you set and how good the insulation of your sauna is. In addition, electricity prices can vary.
