The time it takes to boil water on a wood stove can vary based on several factors, including the type of wood stove, the efficiency of the stove, the size and type of pot or container used, the amount of water, the type of wood being burned, and the intensity of the fire. As a rough estimate, it may take anywhere from 10 to 30 minutes or more to boil water on a wood stove.
Wood stoves can have varying heat outputs, and some are designed for more efficient heating than others. Additionally, hardwoods tend to burn longer and produce more heat compared to softwoods, so the type of wood being used can also affect boiling times.
It's important to monitor the water closely while it's on the wood stove to prevent over-boiling, especially if the water is in an uncovered container. Once the water reaches the boiling point, it will remain at that temperature until most of it evaporates or until you remove it from the heat source.
Remember, safety is paramount when using a wood stove. Make sure to follow all safety guidelines, keep a close eye on the stove while it's in use, and use appropriate fire-resistant cookware or containers to boil water.
