Central Wood Biomass Masonry Heater

Biomass wood energy is stored during a tree's growth. A central masonry heater, with a special refractory core and extended heat-exchange flue, absorbs heat from a relatively short and hot fire. Long-term radiant heat storage and distribution is accomplished with high efficiency and very low emissions. An hydronic heat exchanger is tied into the geothermal radiant heating system.
