HUUM STEEL Electric Sauna Heater

Don’t be deceived by the HUUM STEEL’s minimalist elegance! This compelling electric heater carries an unexpected abundance of stones, delivering potent yet gentle, enduring warmth. Cleverly hidden within its streamlined design is a sturdy built-in air tunnel, promising swift and efficient heat, belying its compact form. Its stunning stainless steel shell provides a captivating contrast against the natural sauna stones, effortlessly elevating the aesthetic charm of your sauna room.


The embedding flange is made of stainless steel and covers the uneven wooden edges around the heater, creating a clean and smooth finish. The embedding flange is useful if you plan to install the sauna heater partially inside the sauna platform. The HUUM Flange CS was designed for use with installation of the Cliff or Steel Series sauna heaters.
