Product Overview

*Stones & Controller to be purchased separately*

(We recommend purchasing 4 x 15kg boxes of the Rounded Olivine Diabase Sauna Stones with this electric heater. You can find the recommended sauna stones here). 

The HUUM DROP electric sauna heater features high-quality materials with an award-winning design inspired by nature. 

The HUUM DROP sauna heater gets its inspiration from a water drop. The round design softens the angular interior of a sauna, giving it a touch of elegance. The compact wall-mounted DROP fits up to 55kg of stones, which guarantees a soft and long-lasting steam, similar to that of wood burning sauna heaters.  

HUUM heaters are manufactured in Estonia, where they are crafted from stainless steel and other high-quality materials. Combined with a stylish, minimalistic Nordic design, the HUUM DROP makes a statement piece in a home sauna.

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).  

Heat Diverter and Heating Elements Retainer (this Huum 'Upgrade Kit' is now included with the Drop 9kW model only):

The HUUM 9kW model includes an additional upgrade kit with a heat diverter and a heating elements retainer. These are NOT included with the 4.5kW and 6kW models. 

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

4.5kW: A= 4 in, 100 mm & B= 23.3 in, 590 mm & C= 17.1 in, 435 mm

6kW: A= 4.8 in, 120 mm & B= 24.8 in, 630 mm & C= 17.9 in, 455 mm

9kW: A= 5.9 in, 150 mm & B= 27.2 in, 690 mm & C= 19.1 in, 485 mm

 *SUFFICIENT AMOUNT OF STONES TO BE PURCHASED SEPARATELY 

Product Specification

This heater must be installed by a qualified electrician. The DROP 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.
