Controlling temperature and timing up to 230℉ and 3 hours, respectively, this heater offers ample stone capacity enabling effective heat storage and steam generation when paired with quality sauna stones from other options on this list.
Buying Guide: Choosing The Right Sauna Heater Rocks
When selecting sauna heater rocks, consider the following aspects to maximize sauna efficiency, safety, and longevity:
Material Composition
- Basalt Rocks: Known for superior heat retention and durability. They absorb and release heat gently without cracking.
- Natural Pebble Stones: Typically river-worn, these have smooth yet heat-resistant properties, safe for consistent use.
- Igneous Rocks: Volcanic origin rocks such as basalt and lava stones have natural heat storage and dispersion advantages.
Heat Retention And Steam Production
The ideal rocks retain heat longer and allow safe tossing of water to produce steam. Look for porous, jagged surfaces rather than smooth stones, as they provide more surface area to generate rich steam.
Size And Fit
Proper sizing (usually between 2 to 4 inches) ensures rocks fit snugly around heating elements. This improves air circulation and enhances heat absorption and retention without air gaps that reduce efficiency.
Durability And Safety
Choose stones rated for high-temperature resistance with no tendency to explode or crack under heat. Stones that discolor, melt or degrade can affect sauna performance and safety.
Weight And Stove Capacity
Match the stone weight recommendations specified by your sauna heater manufacturer. Overloading or underfilling can impair heater function and longevity.
Maintenance
Opt for stones that are easy to clean and maintain. Regularly inspect for cracks or dust buildup, replacing stones as necessary to maintain safety and performance.
Compatibility
Ensure stones are compatible with your sauna heater type — electric, wood-fired, or infrared heaters may have specific rock requirements or size limitations.
