Steam Boost 650

The Steam Boost 650— a passive steam intensifier that sits on top of the sauna stones. Water poured into the reservoir hits a heated distributor plate and vaporises instantly, producing a bigger, more sustained plume of löyly than throwing the same amount of water directly on the pile.

Turns a regular electric heater into something closer to the löyly experience of a proper wood-burning stove without any wiring changes.
