The Harvia Forte electric sauna heater is an always-ready solution designed for frequent sauna users who value immediate heat, safety, and energy efficiency. With its innovative heat-storing design, the Forte allows you to enjoy a relaxing sauna experience at any time by simply lifting the cover and throwing water on the hot stones.
The Harvia Forte offers exceptional flexibility, allowing you to enjoy anything from an extremely humid steam bath to a hotter and drier sauna session, depending on your preference. It is equipped with a separate splash-proof control panel, making it especially suitable for embedding into a bench while keeping controls easily accessible. Designed with family safety in mind, the heater automatically switches off if the cover is left open, and the control panel includes a keypad lock to prevent accidental adjustments. Additionally, the ECO mode helps save electricity by maintaining the heater at a very low temperature without completely turning it off, ensuring the sauna is always ready while remaining energy efficient.
