Savings: When used by a family, an ordinary electric sauna consumes about 1,000 kilowatt hours of electricity each year. This accounts for more than one tenth of the year’s electricity consumption. The best sauna temperature is 70 to 80°C. Heating a sauna to 100°C increases electricity consumption by 20 to 30%.
Remember this: It may be difficult for many people to break the habit of taking a sauna several times per week. Keeping a sauna hot when it’s empty is the most unnecessary waste.
Reducing your carbon footprint: Giving up one sauna visit each week reduces your carbon footprint by 1% per year. If a million Finns did this, it would save the equivalent of 9,000 carbon footprints.
