I have a large 6ltr teapot sitting on our wood burner during winter. It heats up to boiling in less than an hour and much quicker if I have it sitting directly on firebox. Woodsman Ebony are good. We use hot water for doing dishes and cups of tea and I have used it for a Filipino shower (warm water in a bucket with a scoop, get wet, soapy up, rinse off). Also the teapot is still warm in the morning after the fire going out over night so adds a few degrees to the inside temperature. A large pot with a tight fitting lid would do the same job but a bit harder to carry and pour.
