Finnleo Laava 14.4 kW (208V 3PH) Sauna Heater

Finnleo Laava 14.4 kW (208V, 3PH) Sauna Heater

The Finnleo Laava 14.4 kW (208V, 3PH) is the highest-output configuration in the Laava heater series, engineered for extra-large residential and standard commercial saunas that demand fast, powerful, and consistent heat. This floor-standing heater delivers exceptional performance from a compact footprint, making it an ideal choice for spacious sauna rooms where efficient heat-up time and steady heat retention are essential. Built by Sauna360 in Cokato, Minnesota, the Laava carries on Finnleo's tradition of authentic Finnish sauna engineering, backed by rigorous safety testing and full North American certification.

Operating on 208V three-phase power, this heater configuration is well suited for commercial installations and facilities where three-phase electrical service is already in place, offering efficient power distribution and reliable performance for high-demand sauna environments.

Construction & Heating Performance

The Laava's floor-standing design uses a robust metal frame that houses the heating elements and rock chamber, promoting even heat distribution and durable, long-term performance in high-use environments. The heater's rock bed, approximately 132 lb, absorbs and radiates heat steadily, producing the soft, enveloping warmth characteristic of authentic Finnish sauna bathing while also allowing for classic water-on-rocks steam (löyly). At 14.4 kW, this model delivers rapid heat-up times and sustained thermal output, making it particularly effective for larger sauna volumes and commercial-use settings where recovery time between sessions matters.

Controls & Compatibility

The Laava requires the SL2-C control and a matching contactor box for safe and proper operation; these components are not interchangeable with other control systems. Buyers can choose a Heater Only configuration for use with an existing compatible setup, or select a complete package that bundles the SL2-C control (available in 60-minute or 24-hour Wi-Fi versions) along with the correctly rated contactor box for the 208V/3PH electrical configuration. The SaunaLogic2® ecosystem allows users to manage heater operation, lighting, and audio from a single connected app, streamlining the sauna experience from a single interface.
