The HUUM DROP 9STU Pkg is a HUUM electric sauna heater made in Estonia, 9 kW, about 283–460 cu ft. DROP is the teardrop wall heater. A lot of stone for a compact wall unit — milder, longer steam than a tiny 3 kW box.
How it heats
Electric elements inside a stone cage. You need a HUUM UKU (or compatible) control — there are no dials on the heater. Round stones are what HUUM recommends. Licensed electrician, heat-resistant cable, no guessed breaker size from us. Glass and masonry: add equivalent volume when you size kW.
