Fancy a cuppa? Who doesn't... especially to start and end a long day of camping activities! This Portable Woodburning Stove Water Heater holds 3 litres of water. It wraps around the bottom flue section and sits on top of any of our Portable Woodburning Stoves. Once the water has boiled the water heater can be turned around and hang from the bottom flue and fill those flasks.
