is high efficiency gas boiler worth the investment? what's ...

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).

Furnace - Wikipedia

The most efficient arrangement for high-efficiency furnaces includes PVC piping that brings fresh combustion air from the outside of the home directly to the furnace. Normally the combustion air (fresh air) PVC is routed alongside the exhaust PVC during installation and the pipes exit through a sidewall of the home in the same location.

Dec 27, 2013 · I learned that high efficiency gas furnaces use two heat exchangers to suck as much heat out of the exhaust as is possible and send that heat directly into your home. This is good because you don't like sending warm air out of your house as exhaust. During this process, the water vapor condenses and has to be drained out of the furnace.

Plastic Vent Pipes for High-Efficiency Condensing Furnaces

High-efficiency condensing furnaces have two-stage combustion to extract as much heat energy as possible from burning gas. After the first stage, the hot exhaust gasses are cycled through a second combustion stage, resulting in exhaust with very little heat. This process creates condensate, or moisture, from the furnace's heat exchanger.
