Product Specification

This heater must be installed by a qualified electrician. The HIVE heater can ONLY be installed on a three-phase 400VAC power supply. 

Please refer to the "HUUM Electric Sauna Heaters - Single Phase Connection" in the "Downloadable Files" tab if installing the electric heater on a single-phase power supply. 

Please ask your electrician to take photos when installing the heater for the first time in the unlikely case there are any issues with the heater further down the line. We will ask for these to diagnose the issue as best as possible.

* We recommend slightly overestimating the Computational Volume for commercial saunas.
