ABSTRACT:
Provided is a sauna heater comprising an upright casing including an upper open receptacle for rocks to be heated and a burner at the bottom of the casing. An air intake communicates with the burner for the supply of air thereto. A heat deflector plate of planar configuration is disposed in the path of the gases within the combustion chamber and such that gases from the burner past the plate end and onto the top and thence downwardly toward a flue. The top of the burner is provided with an arcuate cover plate supporting the piled rocks. Upon heating the rocks, water is poured thereon to provide steam at a desired level. Excess water not absorbed by the heated rocks is drained in a free flow from the cover plate and directed to passage ways isolated from the combustion chamber and extending from the extremities of the cover plate to a point well below the bottom of the burner.
