How do condensing boilers add efficiency? - HeatGeek

Mar 24, 2021 · This means that the boiler efficiency rate can reach up to 90-91% at full condensation (80% from fuel burning and 11% from steam condensation). In a condensing boiler high-performing heat exchanger, the released gases are cooled to a temperature level that is almost equal to the water temperature from the reverse loop. Therefore, the coefficient of efficiency approaches the 91% mark,

Condensing boilers in practice : Dr Paul Bannister

Just as striking, is how much more efficient the boiler is at low load (25% input) than at full load ( input). This is because the reduced flows of gas and air through the boiler mean that the condensation process can happen more efficiently. As a result, the combustion efficiency of condensing boilers improves markedly at low load.

Is a high efficiency, condensing gas boiler the best

Aug 13, 2018 · An ultra-high efficiency boiler is able to keep more heat in the heating system, but the side effect is condensation. So, back to the word condensing. As previously mentioned, the byproduct of harvesting more heat from the flue gas is the formation of condensate in the heat exchanger.

Condensing boiler - Wikipedia

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.

What temperature should a condensing boiler be set at

For the boiler to work at its most efficient, the heat exchanger needs to be equal to or below the dew point temperature. The dew point temperature is a measurement that determines the humidity of air and is the temperature at which water droplets form in the heat exchanger. For gas boilers, the dew point is

Next we must understand state or phase change. Every time H20 changes phase from solid to liquid or gas, it either absorbs (Endothermic) or releases (Exothermic) whats known as latent heat. The values vary depending on source and other conditions such as pressure but generally at atmospheric pressure the following applies Melting: absorbs 330,000 J/kg of latent heat Evaporation
