A boiler is a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil. (In North America, the term "furnace" is normally used if the purpose is not to boil the fluid.) The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation.

    Can't find my filling loop!

    I need to pressurise my Vaillant ecoTEC plus 618 Boiler, but can't find the filling loop! It's not under the boiler itself... (IMG_1696.jpg) And I'm uncertain about the pipes around the water tank upstairs (see pictures attached) -- can you see anything there? Where do you think it could be?
