HUUM Drop Electric Sauna Heater

5 reviews|1 answered question

Water and heated stones are the heart of every sauna.  Drawing inspiration from a single drop of water, the HUUM DROP is crafted to elevate the beauty and performance of these elements.  We think of HUUM DROP as a very functional piece of art, but it’s also been a reliable, trusted heater in since 2013 in Northern Europe, where it was awarded the prestigious Red Dot Design Award.

Each DROP features an exceptional stone capacity of 122 pounds for long-lasting steam that’s not smothering or oppressive.  Like it hot?  HUUM heaters are the only choice on the North American market designed to exceed 194°F and can reach 230°F.  Also unique to HUUM is the 18 hour timer, perfect for commercial saunas and those days you’ll want to share your sauna with friends, family, and neighbors.

Q & A

Is it true this can't be installed if temps are below zero F? Ron asked on

The heater itself can be installed in temperatures below -5F. The power unit and control however do have a minimum operating temperature and the lowest they go is -5. See below for specs of the main module and digital control.

In areas where it will regularly go below these temperatures, we recommend installing the equipment in the house and having your power runs come out of the main module in the house to the outdoor sauna. Another alternative to look into could be using heated weatherproof electrical enclosure, these enclosures will keep the ambient temperature in the enclosure to a certain temperature so that electronics can operate with no impact from the outdoor temperatures.

Temperature Rating: -4℉ to 145℉
Protection: IPXX (not protected)

Temperature Rating: -4℉ to 104℉
Protection: IP65
