HUUM CLIFF Electric Sauna Heater

Description

HUUM CLIFF Electric Sauna Heater

*stones & controller to be purchased separately*

 

(We recommend purchasing 5 x 15kg boxes of the Ø 3-5 cm of rounded olivine diabase sauna stones with this electric heater. You can find the suitable sauna stones here.)

 

About this HUUM Electric Sauna Heater 

The HUUM CLIFF is a slim electric sauna heater with remarkably small safety distances and an award winning design. 

The HUUM CLIFF electric sauna heater features a stylishly simplistic Nordic design. This sauna heater is a real space saver and perfect for smaller home saunas. Thanks to the well-optimized structure of the CLIFF, required safety distances from the sides of the heater body are only 6cm in the smaller models and 24cm in the more powerful models. 

CLIFF is also available in a wall-mountable model, which is suitable for even smaller sauna rooms. 

 

Controller: Depending on the controlling system you will opt for, the heater can be purchased either with the  UKU Local (an easy-to use controller without Wi-Fi or mobile functionality), or the  UKU Wi-Fi Controller (a remote-control option with Wi-Fi capabilities).  

 

Safety Distances: See the wider image bank of this heater for a diagram about this heater's safety distances:

6kW: A= 60 mm & B= 390 mm

9kW: A= 240  mm & B= 750 mm 

10.5kW: A= 240 mm & B= 750 mm

Product Specification

This heater must be installed by a qualified electrician. The CLIFF heater can be installed on both single-phase 240VAC and three-phase 400VAC power supplies. 

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.
