Harvia Moderna is the royalty of electric sauna heaters. Moderna will heat up your sauna quickly – and thanks to the digital control, to the exact temperature you want, to the accuracy of a single degree. A separate electronic sensor maintains a steady temperature for as long as you need. Moderna’s digital Xenio XE control panel makes it extremely easy to use. All the functions are integrated directly to the Moderna heater, enabling easy installation whether you are building a new sauna or putting in a new heater in your old sauna.
