Patent ID: 8032979

Claim:
A liquid heating system, comprising: a first pipe structured to convey hot gases from a first independent source of relatively higher temperature gases; a second pipe structured to convey hot gases from a second independent source of relatively lower temperature gases; a heat exchange chamber that is coupled for receiving a mixture of hot gases from the first and second pipes thereinto and having a heat exchange mechanism that is structured for passing pressurized liquid therethrough, the heat exchange chamber being further structured for exhausting the mixture of hot gases; a temperature sensor positioned within the heat exchange chamber; and a diverter coupled between the first pipe and the heat exchange chamber, the diverter being structured for diverting the hot gases from the first independent source of relatively higher temperature gases away from the heat exchange chamber as a function of a temperature of the heat exchange chamber, as measured by the temperature sensor, while the heat exchange chamber continues to receive the hot gases from the second independent source of relatively lower temperature gases; wherein the temperature sensor is structured to detect a maximum chamber temperature and a minimum chamber temperature, and wherein the temperature sensor and diverter are operable to prevent the heat exchange chamber from falling below the minimum chamber temperature and from rising above the maximum chamber temperature.
