HUUM Drop 4.5: a wall mounted electric sauna heater for rooms from 106 to 247 cubic feet
The HUUM Drop 4.5 is a wall mounted electric sauna heater made in Estonia, rated at 4.5 kW for small rooms from 106 to 247 cubic feet. Shaped like a drop of water, its rounded stainless steel bowl measures about 15 inches wide, 13 inches deep, and 23 inches tall and weighs only 24 pounds. The design won Europe’s Red Dot award. Even at this size, it holds 122 pounds of stones, more than many wood stoves. The stones sit directly on the heating elements, so the heat comes from the rock 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 in one order? See the HUUM Drop 4.5 heater package. The HUUM Drop 4.5 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What size sauna does this 4.5kW heater fit?

How big is the heater itself?
It is a compact wall-mounted unit measuring 15.4 inches wide, 13.2 inches deep, and 23.3 inches tall, weighing 24 pounds before stones. Mounting on the wall keeps the floor clear, which is a real advantage in the small rooms this size serves.
