Jet-stream Technology: Cold water, which returns from installation, are sent towards front side from rear section of the boiler by means of a jetting pipe. A pressure drop happens at the place where cold-water jet is sprayed in to the boiler. By means of this vacuum created by this pressure differential, some of hot boiler water, which stays within rear sections, is drawn towards downwards and a reverse water flow is created at this region. Hot water mixes with cold water at lower passages of the boiler and increases the temperature. Thus, cold-water jet is heated without contacting the cast surfaces, where fumes are collected, and main effect of condensation is eliminated.
