The Sauneco Ignis-V50 external wood-fired hot tub stove is built from high-quality, seawater-resistant marine aluminium — up to 30% more thermally efficient and considerably lighter than a comparable stainless steel furnace, while holding its shape for years rather than warping over time. Positioned outside the tub and fitted with a 2-metre stainless steel chimney, it circulates water using natural thermosiphon action, so no electric pump is required. Every welded seam is MIG-welded and pressure-tested for a leak-free, long-lasting build, making it a dependable choice for hot tubs up to 240cm.
