Sawo 6kW Heater

A robust, high-capacity heater for 5–9 m³ saunas The Sawo Scandia 6kW is a wall-mounted electric sauna heater built for small-to-medium home saunas and residential wellness rooms. It's part of Sawo's Scandia range, one of the brand's most established heater lines, known less for flashy design and more for a heavier stone load and a body built to handle frequent, everyday use. Sawo Inc. is a Finnish-managed sauna manufacturer that has been producing heaters, sauna rooms, and steam equipment since 2000, shipping worldwide. The Scandia line reflects that manufacturing focus: fewer frills, more emphasis on stone capacity and heat retention, which matters most once you're actually running the heater session after session. Key specifications Power output: 6.0 kW Recommended room size: 5–9 m³ Suitable for: 3–6 person sauna rooms Housing: Robust stainless steel body, increased durability over lighter-gauge heaters Stone capacity: 18–22 kg (noticeably more than many heaters in this power class, which improves steam quality and heat-holding capacity) Stones sold separately Note: heavy item shipping rates apply for this item Control options: NB models: built-in control unit (timer/thermostat on the heater) NS models: no built-in controls; pairs with a separate Saunova or Innova control unit (including WiFi-capable options) Approximate dimensions: ~410–515 x 290 x 450 mm depending on model variant Mounting: Wall-mounted, hardwired Why the extra stone capacity matters Most 6kW heaters in this class hold somewhere around 15–20 kg of stones. The Scandia's 18–22 kg capacity gives it a real edge for anyone who throws water on the stones regularly (löyly) rather than just running dry heat: more stone mass means more thermal buffer, so the steam stays consistent instead of cooling the heater down between throws. This is the kind of detail that matters more in practice than on a spec sheet, and it's a big part of why the Scandia has stayed a popular residential choice rather than being replaced by newer, sleeker models. Built-In vs. separate controls: which to choose Choose an NB (built-in control) model if you want the simplest install: no separate control panel to wire and mount, controls live on the heater itself. Choose an NS (separate control) model if you want the control panel located outside the sauna room, or if you want WiFi/app-based scheduling through a Saunova or Innova controller. This is the more flexible option for anyone integrating the sauna into a smart-home setup, but it requires purchasing the control unit separately. Installation notes Like any 6kW sauna heater, the Scandia is a hardwired appliance, not a plug-in unit. Installation requires: A dedicated circuit sized for 6kW output Installation by a licensed/qualified electrician Correct circuit protection (RCD/MCB) per local electrical code Proper safety clearances from benches, walls, and combustible surfaces per the Sawo installation manual A safety cutoff switch is standard: the heater will shut off if an object (like a towel) contacts it or breaches the minimum safety distance Skipping a licensed electrical install isn't just a warranty issue; with a 6kW load, it's a genuine fire and shock risk. Always follow the manufacturer's manual and local code. Who it's for Homeowners who steam heavily and want more stone mass for consistent löyly Anyone replacing an older, undersized heater in a 5–9 m³ room Buyers who want the option of smart/app-based control (NS + Saunova/Innova) rather than being locked into a fixed built-in panel Care & maintenance Use Scandia-appropriate stones (e.g., olivine diabase) sized for good airflow between stones; don't substitute soft or undersized rock Restack loosely rather than packing tightly; tightly packed stones trap heat unevenly and shorten element life Check stones for cracking or breakdown every 6–12 months depending on use frequency, and replace as needed Wipe the stainless housing with a damp cloth only; avoid abrasive cleaners Ready to bring the Scandia's steady heat and consistent löyly to your sauna?
