Making Hot Water with a Rocket Mass Stove
As you can see from the rocket mass heater design - getting the firing chambers insulated to keep the burning as hot as possible (chimney fire temperatures) is as important as the fire technology itself.
When heating liquids using the design, any cooling prior to the burn disrupts the perfection of the burn so it is best to do it below the after burn. which is still able to exceed temperatures of 200 - 300 degrees F.
