HUUM Drop 7.5: a 7.5 kW wall heater for saunas from 230 to 441 cubic feet
The HUUM Drop 7.5 is a wall mounted electric sauna heater made in Estonia, rated at 7.5 kW for rooms from 230 to 441 cubic feet. Its rounded stainless steel body is shaped like a drop of water, a design that won Europe’s Red Dot award. It measures about 15 inches wide, 13 inches deep, and 23 inches tall and weighs 25 pounds. That compact body holds 122 pounds of stones. The stones rest directly on the heating elements, so the heat comes from the rocks and the steam lasts.
The box holds the heater, its wall bracket, and the manual. It needs a HUUM UKU control to run, and you add that on the page. Choose the Wi-Fi version and you can start the sauna from your phone. Sauna stones are sold separately, so add the 4 boxes it needs on the page. A safety rail, an embedding flange, and a bucket and ladle set are optional. Want the control and stones bundled in? See the HUUM Drop 7.5 heater package. The HUUM Drop 7.5 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
