Steam Generator - an overview | ScienceDirect Topics
Boilers are essentially shell-and-tube heat exchangers, with water being boiled to steam or transformed to high pressure hot water. Heat is generated by burning a fossil fuel; the combustion gas can be ducted around tubes containing the water (water-tube boiler), or the hot gas can pass inside the tubes with the water being in the shell (fire-tube boiler).

Hot taps don't fire up combi | Screwfix Community Forum
2015/7/22 · For good measure (though now I realise maybe not so smart), I also ran the hot pipes part of the way from the boiler to the bathroom in 22mm, the rest in 15mm.
