|Description=A condensing boiler extract heat from the otherwise wasted exhaust gases. It has a larger or a secondary heat exchanger which causes the hot exhaust gases to lose much of their energy during the combustion process. This pre-heats the water in the boiler system in a highly energy efficient way, extracting more energy from the fuel than conventional boilers. At its peak efficiency, the vapor produced condenses back into liquid form (the condensate), thereby releasing the latent heat of vaporization. There are boilers fired by gas and other fired by oil.
 
|Advantages=Energy efficient: Operating efficiencies of 90% or better can be achieved
 
|Disadvantages=The condensate is slightly acid and needs to be piped to a drain or soaked away
