  • The most common reason for condensing boiler breakdowns

    Jan 04, 2011 · Probably the most common reason for a condensing boiler to fail to provide heat is due to loss of pressure. The heating circuit on most condensing boilers is a sealed circuit. It is usually pressurised to one bar. Most condensing boilers are designed to stop providing heat if the pressure in the sealed heating circuit…Learn More

  • What Pressure Should My Boiler Be? | Vaillant

    A boiler's pressure gauge will usually sit between 1 and 2 bars when it is turned on. The exact recommended pressure level will vary depending on the boiler manufacturer, but generally, anywhere between 1.0 and 2.0 bar is ideal. The boiler pressure level will rise when heating a home or providing hot water. However, it should still stay below Learn More

    Process 4-1: Heat transfer to the working fluid as it flows at constant pressure through the boiler to complete the cycle. We will consider the Rankine cycle with water as the working fluid. Process 1-2: Assuming that bulk kinetic and potential energy and heat transfer are negligible, the power produced by the turbine is given by W t = m (h 1-hLearn More

  • What to do if your boiler loses pressure - British Gas

    A condensing boiler takes water from the pressure supply mains. The water is heated in the heat exchanger until it reaches the correct temperature. Then you pump it to the hot water tank, where it can stay hot for some time until you need it. This makes a condensing boiler a better option than a combi boiler, especially for a large home.Learn More

  • Condenser - Function & Working - Engineering Insider

    If your central heating system is turned off the boiler pressure should be between 1 and 1.5 bar. This means that the needle should still stay in the green area of the pressure gauge. Depending on the make of your boiler, the recommended optimal working pressure by most manufacturers is 1.3 bar.Learn More
