    No Ordinary Heater Design

    Engineered and crafted in Northern Europe at the core of the awe-inspiring Model S4 lies its ingenious self-cleaning corrugated stove, a true marvel of ingenuity. Equipped with a secondary chamber, this innovative creation masterfully harnesses the heat emitted from the smoke, resulting in an unprecedented reduction in wood consumption of up to 50% when compared to conventional hot tubs. The brilliance of this design extends further, as the air circulating between the fiberglass lining and the wood exterior is ingeniously super-heated, accelerating the heating process to new heights.

    This incredibly efficient wood stove will heat 304 gallons of water from 40°F (5°C) to 95°F (35°C) in 1.5 to 2 hours – the fastest-heating wood burning hot tub available.
