ABSTRACT:
Steam heating equipment for the interior of a room recirculating heating fluid after it has condensed in a heat emitter for heating the room. The heat media liquid is sealed in an enclosed steam generator which supplies steam to the heat emitter via a steam conducting pipe. The heat media liquid which has condensed in the emitter by giving up its latent heat to the ambient air, is stored inside a condensed liquid vessel which is under atmospheric pressure. When the heat media liquid inside the steam generator has been depleted to a certain level, the heating of the steam generator is stopped. The heat media liquid which has previously been stored inside the condensed liquid vessel is then recirculated into the steam generator through a liquid circulation pipe which is separate from the aforesaid steam conducting pipe, by utilizing a pressure reduction action within the steam generator causing its cooling. When this liquid circulation has been completed, the cycle of heating up the steam generator again for sending out its steam, is repeated.
