The Ignis-S45 is a 45kW internal wood-fired hot tub stove built from high-quality, seawater-resistant marine aluminium. Designed to sit submerged beneath the waterline, it heats your hot tub from within — water circulates naturally between the stove and the tub through a dedicated channel, delivering efficient, even warmth without the need for an external heater unit.
Suitable for hot tubs up to 7.87 ft (240 cm) in diameter, the stove is loaded and fired from above, making it straightforward to use during a session. Marine aluminium conducts heat approximately 15× more efficiently than stainless steel, making this stove up to 30% more effective. The 3 mm thick shell is twice the thickness of standard stainless steel units, yet 30% lighter — and aluminium holds its shape over time, where thin stainless steel can warp with prolonged use. Every weld is completed using high-quality MIG technique and individually tested for impermeability before dispatch.
