Understanding the Role of Sauna Stones in a Tylo Sauna Heater

At the heart of an electric Tylo sauna heater is its stone compartment—stones absorb heat from the elements, store it, and release it evenly. They also allow water to be sprinkled to generate steam (“löyly”), which enhances the sauna experience. As one manufacturer notes, optimum water sprinkling and direct contact between stones and heating elements lead to “perfect water vaporisation.”

Stone Behaviour in the Tylo Design

The Tylo sauna heater Sport 2/4 is built with a deep stainless steel stone compartment, ensuring good thermal mass without excessive bulk that would slow warm‑up.

The manufacturer emphasises that they ensure “the right quantity of stones” matched to the heater’s output. Too many stones can:

• Prolong heat‑up time
  
  

• Reduce responsiveness
  
  

• Increase energy use
  
  

Because the stones are designed specifically for the heater’s power output, you get quicker warm‑up and consistent steam performance—ideal in smaller spaces where responsiveness matters.

Getting the Stone Setup Right

Best practices for using and maintaining sauna stones in a Tylo sauna heater like the Sport 2/4 include:

• Use the correct stone type: Typically igneous rocks such as dolerite or black diabase that can withstand rapid heating and cooling.
  
  

• Fill the compartment properly: Load the stone compartment to the recommended level (usually just below the grid). Avoid over‑packing.
  
  

• Use the heater regularly: After the first few uses, stones may shift. Check and re‑position them if needed. Top up or replace damaged ones.
  
  

• Sprinkle water properly: Use small, controlled amounts rather than dumping large volumes. This ensures effective steam without straining the heater.
  
  

• Replace stones periodically: Over time, stones crack or deteriorate, reducing efficiency and steam quality.

Conclusion

Sauna stones might appear simple, but they’re a core part of the sauna experience—especially when using a Tylo sauna heater in a smaller room. With the right stone type, layout, and maintenance routine, you’ll maximise both heater performance and the authentic steam experience that makes saunas so revitalising. For compact environments, this attention to detail makes all the difference.
