HealthHQ Axion Wood Fire Sauna Heater Stove

Outdoor Wood-Fired Sauna Stove with Stone Cage There's something elemental about wood-fired heat. The HealthHQ Outdoor Wood-Fired Sauna Stove is built around that ritual — an exposed cage of glowing sauna stones, a live fire burning behind glass, and a wave of deep radiant heat that no electric heater can replicate. Designed for permanent outdoor sauna installation and delivering up to 18 kW, this 304 stainless steel powerhouse is engineered to handle New Zealand's outdoor conditions year-round and keep performing season after season. Features Exposed Stone Cage — Raw Heat, Full Radiation The open cage basket is the centrepiece of the design — fully loaded with sauna stones and fully exposed to the room. Stones absorb and radiate heat in every direction, delivering the deep, enveloping warmth that defines a true wood-fired sauna experience. Outdoor-Grade 304 Stainless Steel Body Built for permanent outdoor installation. Corrosion-resistant, moisture-resistant, and built to hold its form through temperature extremes — no rust, no maintenance headaches, no compromises. Glass Viewing Door — The Fire Is Part of the Experience Watch the flames work through the glass door. Functional, yes — but more than that, it's atmospheric. The visual warmth of a live fire adds a dimension no digital display can match. Internal Chimney Configuration — Clean Install, No Exterior Pipe The chimney routes internally through the cabin roof, keeping the exterior clean and the installation seamless. Includes a waterproof outdoor cover for a fully weather-tight finish. Universal Stone Compatibility Works with any sauna stones — Olivine Diabase recommended for optimal heat retention and longevity. You'll need approximately 4–5 boxes to fill the cage properly (stones not included). 1-year manufacturer warranty Specifications Material: 304 stainless steel Heat output: 15–18 kW Unit dimensions: 1800*2400mm Flue / chimney diameter: 115mm Stone type: Any sauna stones (Olivine Diabase recommended) Stone capacity: 100kg (5 boxes) What's Included Stove unit Internal chimney kit with waterproof outdoor cover Accessories pack Packing Dimensions Burner crate: 48 × 55 × 77 cm (plywood) Large chimney crate: 32 × 32 × 123 cm (plywood) Small chimney crate: 24 × 24 × 82 cm (plywood) Accessories carton: 63 × 24 × 65 cm Installation Designed for installation in outdoor sauna cabins.
