Gas condensing boilers represent the latest in boiler technology by reusing the 'latent' heat from the flue gases, reducing the flue temperature and toxic emissions (90% less CO and 80% less NOx). A Combi boiler may be the desired choice to supply both

The term "condensing boiler" refers to the fact that the boilers produce condense from time to time. Condensing boilers use heat from exhaust gases that would normally be released into the atmosphere through the flue. To use this latent heat, the water vapour …

A condensing commercial boiler operates at peak efficiency when the water returning to the boiler is lower than the temperature of the condensing flue gas—in the range of 45–50ºC. Otherwise the flue gases will not cool enough to recover the latent heat. If an existing distribution system is designed for high temperature water, look into

14/4/2020 · This latent heat is in addition to the sensible heat. Finally, it is also important to understand the effects of pressure and temperature on the physical state of water. When you boil water as part of a classroom science experiment, for example, you are boiling water at atmospheric conditions.

28/1/2016 · Some boiler manufacturers currently add a secondary heat exchanger or recuperator to improve the efficiency of conventional, non-condensing boilers. In this case, a secondary heat exchanger recovers the latent exhaust heat from the flue gases, condensing water vapor in the process.
