The Rondo is one of Helo’s super-insulated storage heaters. Rondo has a round shape and patented 360 degrees rotating hatch. The hatch can be choose to install at any angle during the installation phase. Thanks to the well-insulated shell of the heater, the 90 kg of stones retain heat extremely well, so you can enjoy a relaxing spur-of-the-moment sauna break. It is designed to be floor mounted, but it can also be integrated into the sauna benches.
