A high efficiency gas boiler (>90%) must have the flue gas condense in order to achieve that efficiency. The flue gas will only condense when the return water temperature is 120 degrees or less. An ordinary system has return water temperature much higher than this, because this is the temperature for which your radiators are sized (typically 180 supply, 160 return).

Traditional gas boilers burn natural gas or propane to heat the water in a home heating system. These boilers are vented to the outside via a chimney flue or vent pipe. Traditional boilers typically operate at higher temperatures, which means that a portion of heat is vented to the outside during the combustion process. Depending upon its age and type, a traditional non-condensing boiler will typically be 80% to 85% efficient. Condensing boilers, are extremely energy efficient because they

May 29, 2019 · What are condensing boilers? Gas boilers work by combustion: they burn carbon-based fuel with oxygen to produce carbon dioxide and steam—exhaust gases that escape through a kind of chimney on the top or side called a flue. The trouble with this design is that lots of heat can escape with the exhaust gases.
