HUUM WaterEx Water/Heat Exchanger adds convenient hot-water capability to your HUUM wood-burning sauna stove by capturing a portion of the stove’s heat and transferring it efficiently to a connected water system.

Its versatile mounting options—rear or lateral placement—allow you to adapt the installation to your sauna layout without compromising performance.
