New York City Commercial Boiler Repair: Condensate .

But that was a waste of energy: boilers that didn’t condense the water out of the exhaust stream can’t rate much higher than 80% efficiency at best, and about 65% was more typical. To squeeze 90% or more of the heat energy out of a gas flame, you must condense the water vapor out of the exhaust into liquid form and recover the heat of ...

Aug 13, 2018· For example, a 30-year old boiler might be 70% efficient, meaning that for every dollar you spend on gas, 30 cents of heat escapes through the chimney or vent pipe. In comparison, a condensing boiler may provide up to 96% efficiency, which means that only 4 cents of heat escapes.

The efficiency of heat produced is directly linked to boiler efficiency. The percentage of excess air and the temperature of the combustion products are two key variables in evaluating this efficiency. The combustion of natural gas needs a certain quantity of air in order to be complete, so the burners need a flow of excess air in order to operate.

Condensing boiler - Wikiped

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
