HUUM DROP Sauna Heater | 9.0kW | Electric Review Summary
What people like
Pros
- Beautiful Aesthetic Design: The unique water-drop shape and polished stainless steel finish provide a modern, high-end look that enhances the visual appeal of any sauna.
- High Stone Capacity: Holding up to 120 pounds of stones, it delivers a much softer, more authentic steam experience compared to heaters with smaller stone reservoirs.
- Smart Remote Integration: The compatibility with mobile applications allows users to pre-heat their sauna from anywhere, ensuring it is ready exactly when needed.
- Efficient Space Saving: Its wall-mounted configuration frees up valuable floor space, making it an excellent option for maximizing the internal area of smaller sauna rooms.
Cons
- Delicate Heating Elements: Some owners have noted that the internal elements can be fragile and may fail if the stones are not packed loosely or handled with extreme care.
- Expensive Total Package: The premium price point is often increased further as the controller, Wi-Fi module, and stones are frequently sold separately from the main unit.
- Complex Stone Loading: Proper installation requires a very specific and time-consuming stone stacking process to ensure airflow and prevent damage to the electrical components.
- WiFi Connectivity Issues: A subset of users reported occasional difficulty syncing the controller with their home network or experiencing dropped signals with the mobile app.
