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.\u003c\/p\u003e\n\u003cp\u003eSuitable 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.\u003c\/p\u003e\n\u003cp\u003eAll prices are fully inclusive of VAT, UK customs fees, import duties, and shipping to the UK mainland.
