Quick Overview

The latest innovation of Helo for the accumulating.

Rondo is one of Helo’s accumulating, ever-ready type sauna stoves. The stove is round and its patented lid turns 360 degrees, which gives you entirely new possibilities to design your sauna interior.

Rondo is controlled by its own control unit, installed inside the sauna room. You can choose the standby temperature and decide the type of sauna bath you wish to achieve by adjusting the temperature of the stones. Rondo’s optimised insulation shell retains effectively the heat produced by 90 kg of stones, letting you enjoy saunas at a moment’s notice. Heat accumulating stoves work very well even with one heating – including the times when the sauna is not in regular use.

The stove is supplied with an easy-to-use handheld controller that can be installed in the sauna (humidity level IPX4). The length of the controller cable is approx. 3 m, extendible by 2 m.

Rondo is a freestanding stove but it can also be integrated into the benches. The safety distances required around the stove are only 10 mm and a 1040-mm clearance above.
