The history of the Vaillant Group dates back to 1874, when Johann Vaillant set up a master fitter's business. In 1894 Johann Vaillant patented a new "closed-system" gas-fired bathroom boiler. [3] This was the first device that made it possible to heat water hygienically, without contaminating it with combustion gases.
Smithies boiler: A development of the pot boiler with added watertubes, used for model steam locomotives. [52] The boiler was invented by F. Smithies in 1900 and developed by Greenly. It consists of a cylindrical water drum hidden inside a larger drum that forms the visible part of the model.
Many models sold in the UK have introduced a small heat store within the combination boiler to address this issue. This "keep hot" facility considerably improves the standard of hot water service, which some people otherwise find unacceptably poor with a combination boiler, but it uses considerably more fuel especially in summer.

erosion of a boiler's plates from the internal water space, particularly where there is a step inside the shell. This was a problem for early boilers made from lapped plates rather than butted plates, and gave rise to many boiler explosions. In later years it was a problem for the non-circular water drums of Yarrow boilers. Handhole
A vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation. Vertical boilers were used for a variety of steam -powered vehicles and other mobile machines, including early steam locomotives .
Babcock & Wilcox-type boiler designs become popular in new installations. 1881 (): Alexander C. Kirk obtained the necessary high pressure boilers for the first practical installation of a triple expansion marine engine in SS Aberdeen.
