As a replacement for oil burning boilers used for out-of-season culture in greenhouse, we have developed a new-type greenhouse heating apparatus using woody biomass, which is lumber from thinning, since 2002. The result of this research will be reported in this paper. We have obtained a basic patent on the heating apparatus in 2007 (patent no. 4048488: application in 2003).
