Determining what is in your saddle can be tricky, but itâs important to know what youâre riding on. Wool flocked saddles will often have what is known as rear gussets (the seam along the back of the panel), although some foam saddles can have gussets to allow them to fit a broader backed horse.
Furnaces and boilers represent the two largest categories of heating systems used for houses and for buildings in general. The main difference between these two heating appliances is what they heat: Furnaces heat air that is distributed by a ductwork system. Boilers heat water that is used in different hydronic heating systems. So-called combi-boilers are designed to supply hot water for washing as well as for whole-house heating. Furnaces and boilers usually burn gas, propane or fuel oil. Less frequently, you'll find units that burn wood, pellet fuel or coal.
Thanks for your reply. In recent years there has been a lot of confusion about the differences between kilns and furnaces. The apparatus for powderglass beadmaking, used in West Africa, is often called a kiln, while I believe furnace is more accurate. Kilns and furnaces have several characteristics in common, but are used differently. A kiln is usually charged (filled with stuff), then heated to fuse the stuff, then cooled, and the stuff removed. A furnace is usually heated first, then charged, then the stuff removed, and the furnace eventually cooled (though not always).
