  • Gas central heating boilers and furnaces - How do they work?

    Aug 09, 2020 · The gas jets play onto a heat exchanger connected to a pipe carrying cold water. The heat exchanger takes the heat energy from the gas jets and heats the water to something like 60°C (140°F). Photo: The gas jets inside a boiler fire up to heat the water. Natural gas burns blue when it has the right amount of oxygen.

  • Why Do Boilers Last Longer Than Furnaces? | ServiceMax

    Steam is an inexpensive and efficient way to transport heat. Not only is it easy to pump through a home (water weighs more and requires more effort to push throughout a home) it holds heat better than just air. A boiler heats up water, turns it into steam and pushes it throughout the home for heating purposes.
