The Coil Kit
Wood-Fired Coil Kit
Already have a tub? We’ve got the coil covered! Heat your hot tub naturally and efficiently with our Wood-Fired Coil Kit, designed for a seamless, off-grid soaking experience. This kit uses natural convection and a process called thermosiphoning to circulate water through a high-quality, food-grade stainless steel coil, transferring heat directly from your fire to your tub — no electricity or pumps required.
Each Kit Includes:
Premium stainless steel coil — durable, corrosion-resistant, and built to last
Food grade, high-temperature silicone hoses – flexible and safe for hot water circulation
All necessary fittings & connections – easy, hassle-free setup
All you’ll need to get started is a drill for installation into your tub.
Perfect for backyard spas, cabins, and off-grid adventures. This setup provides steady, consistent heating. Just fill your tub, stoke your fire, sit back and let nature do the work.
Lead Time: 6-8 weeks
