This is a bit messy, but I was in a hurry to heat water to do some cleaning. I heated the water because it was COLD and WINDY that day.
There was no power or running water the first several nights we stayed, so I heated water for cleaning and bathing on top of a cast iron wood stove we removed from the house. This was a very effective little "stove top," and I kept the gang filled with hearty meals with it. I cleaned up quite a bit of the yard as I used the twigs, pine cones, and magnolia cones too. I shifted the top bricks to fit the size of the pan or pot I was using.
