    the boiler, the flue gases make 1, 2 or 3 passes through the water stored in the pressure vessel. For a 2-pass boiler, there is only one bank of tubes, for a 3-pass boiler there are 2 tube passes and for a 4-pass boiler there are 3 tube passes. After leaving the convective section of the boiler, the flue gases exit the pressure vessel at the stack.Learn More

    2.2.2 Water tube boilers Water tube boilers are designed to circulate hot combustion gases around the outside of a large number of water filled tubes. The tubes extend between an upper header, called a steam drum, and one or more lower headers or drums. In the older designs, the tubes were either straight or bent into simple shapes.Learn More

  • What temperature should a condensing boiler be set at

    The maximum temperature that we recommend you set your radiator output to is 80 °C. If you have a conventional boiler system, your water cylinder will have its own thermostat. This is usually fitted on the side of the tank. You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C.Learn More
