A standard boiler gives off waste gases through a flue and into the atmosphere at a high temperature of over 200 degrees, where this is significantly reduced in a condensing boiler. The heat input is pretty much the same at about 250 to 350 degrees, but a condensing boiler has a much more efficient way of working compared to other types.

Condensing boilers have a Flue Gas Heat Recovery System, not found in non-condensing units, which captures heat from waste gases to preheat cold water from the mains as it enters the boiler. In non-condensing units, this heat from waste gases would be lost, so by making the most of this heat, condensing units use less energy, become more

Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.

Condensing boilers are so much more effective because they are sealed systems meaning they extract heat from flue gases which would have otherwise been lost by a non-condensing boiler. Condensing boilers were not overly popular when they first hit the market, with early teething problems and a collection of myths about their reliability putting

Condensing boilers work to recover heat that a non-condensing boiler would have lost via the flue. This is called a flue gas heat recovery system and works by recovering heat by recycling exhaust gases (mostly hot steam with some acidic content) that older non-condensing used to waste.

A condensing boiler is one of the most efficient types of boiler. This is because it is able to recover virtually all the heat from the flue gases and use this to heat your home. For the boiler to work at its most efficient, the heat exchanger needs to be equal to or below the dew point temperature.

How does a condensing boiler work? With a non-condensing heat-only boiler, some heat is wasted in the form of hot gases released from the flue. A condensing boiler captures some of the heat from these gases and uses it to heat water returning from your central heating system. It therefore requires less heat from the burner and is more efficient.

The steam piping is directed through the flue gas path in the boiler furnace, an area in which the temperature is typically between 1,300 and 1,600 degrees Celsius (2,372 and 2,912 degrees Fahrenheit). Some superheaters are radiant type, which as the name suggests, they absorb heat by radiation.

May 06, 2020 · The gases exiting the flue of a condensing boiler typically have a temperature of 50-60°F, while the gases exiting the flue of a non-condensing boiler usually have a temperature of 120°. This discrepancy in temperature is an indication of the extra heat being extracted from the gases in a condensing system.

The ideal placement of a boiler flue depends on a number of factors. According to the boiler flue regulations, regard should be given to the following issues when determining the appropriate placement: Distance from windows and doors. A boiler flue should not be placed close to any part of your home that can open, such as windows or doors.
