ABSTRACT:
A novel semi-instantaneous, modulating and condensing gas fired water heating system having a very high dynamic response for supplying potable water on demand at a substantially constant, controlled temperature having a maximum output of approximately 1,000,000 BTU/hour is provided. The device includes combustion means, heat exchanger means, and temperature control means having thermal measuring means and controlling means for controlling the rate of heat transfer in anticipation of changes in BTU requirements. The heat exchanger includes a combustion chamber open at its bottom to receive the combustible mixture of air and gas burned by the combustor. Enclosing the combustion chamber is a water chamber having a channel defined by the walls of the combustion and water chambers. Through the channel flows upwards the liquid, preferably water, to be heated. A plurality of tubes extend through and from the top of the combustion chamber along the outside and length thereof, preferably in helical fashion, to form a conduit for the hot fluids to pass in counterflow to and in heat exchange relation with the liquid. The gases are cooled in traversing the counterflow heat exchanger below the due point of the gases causing the vapor in the gases to condense.
