At the Masonry Heater Association Annual Meeting of 2016, I was asked to lead a project which included a cooktop and a long heated bench. The project is based on fairly classic Rocket Mass Heater construction with the main innovation being transforming the primary quick heat exchanger from a recycled metal barrel toward a palatable and useful cooktop.
Here were our drawings for the project:
We used insulated fire brick for the heat riser and employed more of a “bell” than a strict cross-sectional flow approach to the design. The cooktop was produced by Dave Wilcox based on our cooktop plans.
