Helo WT Tank for Havanna and Rocher Heaters (SP0043273)

Helo WT Tank for Havanna and Rocher Heaters (SP0043273) is a Helo-WT passive steamer designed for electric sauna heaters. It uses the heater’s radiant heat, so no separate power connection is needed. By adding steady humidity, it creates a softer and more comfortable steam during the entire sauna session. The more humid air can feel warmer on the skin, which often lets you start bathing already around 55–60°C.

The tank holds about 2 litres of water and typically begins to boil after 12–15 minutes of heating. A full tank usually provides steam for roughly one hour, making it ideal for regular sauna use. For the best performance, fill the tank with clean drinking water and avoid very hard water if possible. Overflow holes help prevent overfilling, and the lid includes a dedicated recess for sauna essence. Add only a small amount of essence at a time to keep the scent pleasant and controlled.

This Helo WT Tank is compatible with Havanna and Rocher heater models and fits neatly between the heating elements when installed correctly.

Installation (Helo-WT)

• Mount the heater on the wall, following the heater manual.
• Place the Helo WT Tank between the front and middle heating elements.
• Correct height: the lid top edge must sit at least 10 mm above the element curves.
• If needed, add a few small stones under the tank for proper position.
• Remove the white protective film from the lid.
• Fit the lid so the filling opening faces the side you will use.
• Fill the remaining element gaps with sauna stones.
• You may also place stones on the lid grille.
