Test result preview
The Stilform sauna heater fulfils all the essential test criteria and impresses with its robust, stable construction and very good workmanship. The visual design of the heater is neutral and appealing, while the controller supplied is functional but less modern in comparison. However, a digital version can be selected for a more aesthetic control. The packaging of the stove shows sustainability aspects. There is no unnecessary packaging waste, although the plastic film could be replaced with more environmentally friendly alternatives. In terms of heat output, the oven delivers a reliable temperature that corresponds to the manufacturer’s specifications and the temperature control is extremely precise. All cable connections and plugs are in perfect condition and free from damage and there was no excessive heat build-up during the test. The user interface of the controller is intuitive to use and responds immediately to inputs, which optimises the user experience. In addition, various sauna stones were tested and found to be fully compatible with the heater under all conditions. As only high-quality materials were used, the heater shows potential for longevity, even if no specific sustainability certificates are available. Overall, the testing institute confirms the high quality and user-friendliness of the Stilform sauna heater in all tested aspects.

Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?
