ABSTRACT:
A wood burning stove includes a water circulating grate within the stove fire chamber which includes horizontally extending, vertically spaced, first and second tubular manifolds. Fuel supporting pipes, including bottom portions which define a "V", physically and fluidly interconnect the manifolds. An inlet pipe extends throughout the majority of the length of the bottom manifold, and the top manifold is connected--through a container having a larger cross-sectional area than the cross-sectional area of the manifold--to an outlet. The inlet to and outlet from the manifold are connected up to a hydronic space heating system. The container supports a heat exchanger comprising a finned copper tube, so that the heat exchanger extends generally horizontally and within the first manifold. The heat exchanger is connected up to a domestic hot water supply. The container also supports one or more electric resistance heating coils, which heat liquid within the container in emergency situations.
