The Wood-Fired Hot Tub: A Definitive Design and Build Guide

THE COMPLETE GUIDE TO BUILDING YOUR OWN WOOD-FIRED HOT TUBImagine stepping outside on a cool evening and sinking into warm water while a fire crackles beside you. The air is cool, the water is warm, and the garden around you has gone quiet beneath the open sky.A wood-fired hot tub makes that possible with a surprisingly simple system. A fire heats the water, while natural circulation carries it through the heating loop without a pump. There's no motor, filter or complicated machinery, just heat, gravity and a carefully designed circulation system.This definitive guide shows you how to turn that simple principle into a working hot tub, with three build routes and a clear method for designing it around your own garden.Sam Blackwell is an experienced contractor who has spent years working with pumps, ponds and water systems. He has built and tested wood-fired tubs using natural circulation, developing the calculations and construction methods set out in this book. INSIDE, YOU'LL LEARN HOW TO: - Choose between three build routes, and understand the trade-offs of each- Size the vessel, heating coil, pipe bore and vertical rise, using a straightforward six-step process- Design the circulation system, including the dimensions and relationships that make natural flow possible- Build the heating system, with the coil, pipework and connections specified- Test the circulation before lighting the fire, using practical checks to identify problems before heating- Keep the water usable for up to two weeks, without chlorine, a pump or a filter- Build from a complete stock-tank example, with the materials, costs and construction sequence worked out- Winterize the tub completely, with a drain-down procedure that clears water from the entire system 28 schematic drawings show you the dimensions, connections, and construction details needed to build it yourself.A complete sample build, detailed throughout the book, gives you a practical reference to follow as you plan and build your own tub.
