How does a condensing boiler work? Your boiler will use either gas or oil as fuel and it will begin to burn when lit. As it does so, it inputs the heat from the burner into a primary heat exchanger. The hot air travels through the heat exchanger and is kept here for as long as possible to bump up the temperature. It will then take this heat
A condensing boiler works on the principle of recovering as much as possible of the waste heat which normally leaves through the flue of a conventional (non-condensing) boiler as water vapour. The best high efficiency condensing boilers convert more than 95% of their fuel into heat, compared to 78% for conventional types.
How does a condensing boiler acheive such high efficiency? The first thing to remember about conventional boilers and condensing boilers is the heat input from the burner is the same. Roughly 250-300 degrees celsius. It is important to understand how a conventional boiler works in order to compare the two. A conventional boiler has one heat
Boiler Control (Not Shown): An electronic module that monitors the safety limits and general operation of a condensing gas boiler. These systems work together in balance to control the combustion process and heat input into the hydronic system. At the heart of the system, the premix gas blower, constantly modulating and adjusting to meet the
Good condensing boilers can attain energy efficiency of 90% or more. Boiler Efficiency Ratings. A boiler’s efficiency is measured by annual fuel utilization efficiency (AFUE). This is the ratio of the boiler’s annual heat output compared to the total annual fossil fuel energy it consumes.
Condensing boiler work by condensing water vapour in exhaust gases which recover latent heat that would otherwise have been wasted or vapourised through the flue. Condensing boilers are also known as high efficiency boilers and achieve in excess of 90% efficiency.
How does a condensing boiler work? Facebook Twitter Email Print It's a device that enables the water for a central heating system (and/or hot water for domestic use) to be heated through the combustion of natural gas, by recovering and utilising all the heat from the exhaust fumes.

How Does a Condensing Boiler Work? If you’re new to boilers, read our boiler buying guide. As fuel (natural gas, propane, or oil) burns inside your boiler system, it produces exhaust in the form of carbon dioxide and water vapor. In a traditional boiler, this exhaust escapes out …
U.S. Boiler includes outdoor reset on our high efficiency modulation/condensing boilers. In fact, to achieve maximum efficiency of a condensing boiler, you must use OD reset. We also offer optional OD reset cards that simply plug into most of our cast iron boiler control systems.
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.
The main reason why condensing boilers are better than non-condensing models is that they are at least 25% more efficient. Their level of efficiency is achieved by using waste heat in flue gas to preheat the cold water entering the boiler , capturing more heat from the outside rather than the inside of a room.
