No power consumption, mainly affected by three aspects
1.The size of the area,
2. The warmth of the steam room design,
3.The steam room has a certain voltage.
1. The larger the area, the higher the power consumption. This does not require analysis. A 100-square-meter steam room and a 10-square-meter steam room will consume a lot of electricity no matter how you use it.
2. The degree of warmth in the design, whether the sealing of the door is good enough, whether there is a thermal insulation layer, and whether the material is used enough are all very important.
As a rough calculation, a 1000W sauna will use about 1 kWh (1 kW/h) of electricity. So, you can calculate the cost by multiplying the energy used by the sauna by the 1 kWh fee charged by the power company.
