  • What is a Condensing Boiler and How Does it Work?

    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.Get Price

  • Benefiting from condensing the size of heating equipment

    In the case of condensing boilers, operating temperature and return temperature then come into play. Condensing boilers are most efficient when they 'are able to' condense. That's why it is even more important to have a wide temperature differential with low return temperature to ensure it is operating in condensing mode (e. g. 70/40°C).Get Price

    Feb 08, 2012 · Condensing B100 biofuel boilers achieve 92-97 per cent GCV efficiency. About 12 litres of air is needed for each litre of B100 biodiesel, so the volume of hot flue gases represents a substantial use of energy. This is partly in the form of sensible heat due to the elevated temperature of the gases, and partly as latent heat in the water vapour.Get Price
