A wood-fired boiler construction is shown having a firebox (15) mounted on a metal base (12) and concrete slab (11) in an insulated shed (13). The firebox is a generally box-like structure constructed from spaced, metal tubular members (16) of generally rectangular cross section, the tubular members each having the wider cross-sectional dimension thereof in the plane of a respective wall. The tubular members are interconnected to provide a free flow of fluid throughout the walls of the box-like structure, and spaces between the tubular members are covered by metal plates overlying and connected to the outer sides of the walls. A fluid storage tank (30) is mounted above the firebox and is interconnected to the firebox to provide a flow of fluid therebetween. The firebox is provided with a door and a chimney, both having dampers therein to control combustion.
