    What people like

    This wall-mounted unit is highly praised for its sleek, modern aesthetic and space-efficient design, making it ideal for small home saunas.

Its durable stainless steel construction and compatibility with advanced mobile controls are frequently mentioned as standout features that enhance the overall convenience and longevity of the sauna setup.

    Pros

    • Space-Saving Design: The compact, wall-mounted profile is ideal for small saunas where floor space is limited.
    • High Stone Capacity: It holds a large volume of stones compared to other heaters of its size, resulting in a softer and more pleasant steam.
    • Premium Build Quality: The heater is constructed from high-quality stainless steel, ensuring durability and a long lifespan.
    • Fast Heating Speed: It efficiently heats up small sauna rooms to the desired temperature in a short amount of time.

    Cons

    • Stones Sold Separately: Users often find that the necessary sauna stones are not included in the base price and must be purchased as an add-on.
    • Limited Heating Range: The 3.5kW output is specifically designed for very small spaces and lacks the power to heat medium or large saunas.
    • Requires External Controller: This model does not have built-in controls, meaning an additional control unit must be purchased and installed separately.
    • Professional Installation Needed: The heater requires specialized electrical hardwiring which usually necessitates hiring a licensed professional.
