how does a boiler Agent heat water

Boilers Explained | Worcester Bosch

A combination or 'combi' boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won't need a hot water storage cylinder or a cold water storage tank in the roof space.

Hot Water Cylinder Guide - Mr Central Heating

The hot water once it passes through the heat exchanger moves back out of the cylinder back to the heating source to repeat the process. The water from the boiler and the cylinder itself are therefore kept separate. As water passes through the heat exchanger it heats up the cold water in the cylinder.

Water Handbook - Preboiler & Industrial Boiler

2021-1-19 · Steam blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall. Under this condition, insufficient water reaches the tube surface for efficient heat transfer. The water that does reach the overheated boiler wall is rapidly vaporized, leaving behind a concentrated caustic solution, which is corrosive.
