What people like
Pros
- Integrated Water Tank: The built-in twenty-liter reservoir allows for convenient water heating directly on the unit, which is ideal for traditional washing rituals without extra plumbing.
- High Build Quality: Constructed with thick steel and a robust cast iron door, the unit is praised for its durability and long-lasting performance in high-heat environments.
- Quick Heating Performance: Reviewers note that the stove reaches optimal temperatures rapidly, efficiently heating both the stones and the sauna room itself.
- Atmospheric Fire View: The glass window in the door provides a pleasant view of the flames, significantly enhancing the sensory and aesthetic experience of the session.
Cons
- Water Boiling Concerns: Users have noted that the water in the tank can begin to boil and create excessive steam if the stove is operated for long periods without drawing off the hot water.
- Hot Metal Tap: The tap used to dispense water from the reservoir can become dangerously hot during operation, necessitating the use of gloves or extreme care.
- Clearance Space Requirements: The unit requires significant safety distances from combustible materials, which may limit installation options in smaller structures without purchasing additional heat shields.
- Heavy Unit Weight: Due to its sturdy construction and the attached water tank, the stove is quite heavy and can be challenging to maneuver and install without assistance.
