Create a warm sprouting bench, heated hoop-house, or wood-fired solar sauna, completely off-grid. This rocket mass heater design includes 30+ pages of detailed plans, beta-testing example projects, and tips on how to orient your sunroom for year-round or seasonal use.
These projects are based on our standard 8" rocket mass heater with J-style firebox, but use damp-tolerant detailing for durability in moist or steamy environments. Heat output from these designs can be enough for a small house, but may not be sufficient to produce tropical conditions in an un-insulated greenhouse in all climates.
