ABSTRACT:
A central heating system furnace includes a self-contained closed-system steam heating unit mounted in a housing having a cold air inlet and a hot air outlet. The unit includes a plurality of side-by-side radiators arranged above a boiler unit having an electric heating element immersed in a quantity of vaporizable liquid. Each radiator comprises a plurality of tubular, finned, heat exchange risers arranged in a row and extending between upper and lower manifolds. In order to distribute steam evenly among each of the radiators and to prevent unvaporized liquid from entering the risers thereof, a horizontal steam tube communicating with the boiler unit is positioned between the boiler unit and radiators and supplies steam to each radiator through a separate steam distributing member in the lower manifold thereof, each steam distributing member including a plurality of steam discharge tubes extending upwardly into the lower portion of different risers of the radiator to distribute steam evenly. A condensate return tube communicates each lower manifold with the boiler unit. A blower circulates air to be heated through the housing over the steam heating unit from the air inlet to the air outlet.
