    Condensing gas combi boilers used to have two heat exchangers, as it's thought that this was more efficient. To begin with, the water was heated in the primary exchanger. As hot waste gases were produced, the water that returned from its circuit around the radiators was pushed into the secondary heat exchanger, which only used waste gas to heat the water.Learn More

  • 7 Best Condensing Boilers | Boiler Replacement Cost

    Condensing boilers are typically designed with a low burner turn-down ratio to 20% or lower. Some of the better boilers have turn-down ratios as low as 5%. If loads drop below the turn-down ratio, the boilers must cycle on and off to meet the load, which can significantly reduce the efficiency of the boiler. When boilers cycle, a pre and post purge of the combustion air in the burner and heat exchanger is required. As a result, every time a boiler is started, cold combustion air is blown through the heat exchanger at the maximum airflow rate for a minute or two; pulling heat out of the boiler and exhausting it. Purge losses are insignificant if boiler cycling is limited to 20 minutes or more, but are significant for fast boiler cycling, like every 5 minutes. We've seen boiler …Learn More

    Now if we can create condensing within a boiler heat exchanger, that's a lot of potential energy to be absorbed. It's also worth noting, on a factual basis, that this is not 'free' energy, this was energy that was within the gas but not transformed into heat during the combustion process.Learn More

    25/6/2016 · Condensing boilers achieve very high efficiency levels by recovering both sensible heat and water vapor latent heat from the flue gas. Research since the 1980's has focused on corrosion in such condensing heat exchangers related to the acidic condensate and material selection.Learn More

    16/12/2013 · In these older, conventional systems, the standard design was to maintain hot water supply temperatures upwards of 180 to 200 F with hot water return always above 140 F to prevent condensing in the heat exchangers. Similarly, conventional, noncondensing boilers were designed so that variable flow through the heat exchanger was unacceptable.Learn More
