How Frequently Should You Replace the Stones in Your Electric Sauna Heater?
The frequency of changing the stones on an electric sauna heater can vary based on usage and maintenance, but it is generally recommended to replace the sauna stones every 1 to 2 years.
Key Factors to Consider
Several factors play a role in determining how often you should replace the stones:
Usage Frequency
If you use the sauna frequently several times a week, you may need to change the stones more often, maybe even after just one year. Regular and intense use can lead to quicker deterioration of the stones.
Stone Condition
Inspect the stones regularly for signs of wear such as cracking or disintegration. Any significant deterioration is a clear indication that it is time to replace them. Regular visual inspection can help you catch any issues early.
Type of Stones
Different types of stones have varying lifespans. For example, volcanic rocks are generally more durable than other types, but this still depends on usage and care practices.
Regular Cleaning
Regular cleaning can prolong the life of the stones. Removing dust and debris that can accumulate over time can significantly extend the lifespan of the stones. Use a soft cloth or brush to clean the stones, avoiding harsh chemicals that can damage them.
Manufacturers' Recommendations
Always check the manufacturer's guidelines for specific recommendations regarding stone replacement. Manufacturers often provide detailed instructions that can help you optimize the performance and longevity of your sauna heater.
Additional Considerations: A Finnish Perspective
In Finland, a common recommendation is to check the stones every year and to change them when they start to erode. This is not solely based on time but on the number of times they have been heated and subjected to cold water.
The rate of erosion can vary based on your usage patterns. For instance, heating the sauna 4 times a week versus once a month will lead to different rates of erosion. Different stone types will also erode at different speeds, making it impossible to give a universal timeline.
To ensure you are doing it correctly, start checking the stones at the bottom, as these often show signs of wear first. You may need to remove the top stones to see the condition of the lower ones and make an informed decision about replacement.
Conclusion
By following these guidelines, you can ensure that your electric sauna heater operates efficiently and provides a good sauna experience. Regular maintenance, including checking the stones and cleaning them as needed, is key to extending the life of your sauna heater and maintaining its performance.
