Frequently Asked Questions
Which Harvia controller do I need for my sauna heater?
Match the controller to the rated power of the heater: the published CX180S controls up to 8 kW, the CX180M controls 9-10.5 kW and the CX180L controls 13.5-18 kW.
Do all Harvia heaters need a separate controller?
No. As published on the heater pages, models marked E require a separate control unit, while XE models and several standard models have controls built in. Check the control type on the heater product page.
