Ring wall II

Quick Overview

Helo Ring Wall II is the ideal stove for home saunas. The stove is mounted on the wall and is therefore a real space-saver, as well as easy to install. Helo Ring Wall II is an excellent choice for those who appreciate practicality, classy design and the soft pleasant steam of a natural stone stove. This stove delivers what is expected, topped with a great price-quality ration.

The stove is available in two models: Ring Wall II STJ is supplied with an integrated thermostat and timer (9 + 3 h), and Ring Wall II D is controlled by a separate controller.

Helo Ring Wall II only takes up less than half a square metre of floor space in the sauna, as its safety distances are only 50-100 mm and both controllers are located on its narrower side.

Helo Ring Wall II stoves are suitable for saunas with a capacity of 4-13 m3 and a minimum height of 190 cm.



Smoothly soft steam

And when you pour water on the stove, the 37 kg of hot natural stones creates a pleasant and smoothly soft steam.

Control options

Ring Wall II STJ incorporates an integrated 12-hour switch and a thermostat. The timer offers a pre-heating time range of 9 hours and a running time range of 0-3 hours. The controls are clear, easy to use and located on the narrower side of the stove.

Several controller options are available for Ring Wall II D: The stove can be controlled by the Digi 1 or Digi 2 controller, together with a WE 3 contactor box. Alternatively, you can use the OT 2 PS-3 controller, or the OT 2 PUi controller, together with the EK 5 P weekly clock.
