Technologies | AERCO

Water vapor, which is a by-product of the gas-fired combustion process, contains significant energy. For every pound of water vapor that is forced into a liquid state, some 1,000 BTU of latent energy, in the form of heat, are released. Effective condensing increases the efficiency by about 10% – turning more of the unit's fuel into usable heat.

What is a heat exchanger in a boiler? | Viessmann

A condensing heat exchanger not only makes better use of the heat from the flue gases. The water that is produced during the combustion process is also condensed. The energy that is released preheats cold fresh water, for example. Alternatively, the heat is also used to preheat the water for other processes or to support heating applications.

This boiler may be arranged in the heating system as a stand-alone unit or stacked upon the heat exchanger to form a compact combination unit as shown in the diagram. In either case the boiler is a completely independent unit from the heat exchanger.

Flue gas and condensing heat exchangers from Bosch

The flue gas flows at the boiler outlet inherently have heat potential at a high temperature level. A flue gas heat exchanger is great to use in order to prevent unnecessary flue gas losses. This efficiency component extracts heat from the hot flue gas and, in return, preheats return water. Maximum efficiency gain when using condensing technology

An Update On Oil Fired Condensing Appliances | Beckett Corp.

"Condensing" furnaces and boilers are so named because they utilize an added "secondary" (typically finned tube) heat exchanger to extract additional heat from the flue gases, reducing flue gas temperature from a typical 500-600°F to around 100°F, and removing the "latent heat of vaporization", which is the heat required to hold

CONDENSATION | Sermeta

Our condensing heat exchangers are based on this principle. Before being evacuated via a chimney, the very hot fumes produced by the combustion of gas pass through the heat exchanger through which circulates cold return water from the heating circuit. The water vapour suspended in the fumes condenses on the tubes that recover the latent heat.

What is a Condensing Boiler and Why Should I Care?

A condensing boiler uses not just the heat from the combustion of natural gas, but also from this otherwise unused energy. Inside a condensing boiler, the vapor is converted back into water droplets, which surround the heat exchanger, which in turn extracts the heat and converts it into additional heating …

What is a Heat Exchanger? | Boiler Guide

The purpose of a heat exchanger is to transfer heat from one fluid to another, hence the name. In the case of a boiler, this means transferring heat from gas to the water that will be circulating around your home to the radiators and hot water tank. Non-condensing units are fitted with just the 1 heat exchanger, whereas modern condensing units
