Water does not expand with heat the way hydrocarbons do. Thus, from an expansion perspective, the water level will not change as the temperature increases. *To correct the answer listed above without deleting it, as I'm new here :) : Water is one of the few elements that expands in its liquid and solid states. The overall expansion is approximately 4%. There are two basic types of boilers used for hydronic heating, water and steam. The level of water in a steam boiler will drop when fired; as the liquid water becomes a gas, less liquid remains in the boiler. Any water boiler used for heating will be constantly "full" as it is essentially a sealed system. Due to the expansion of the water when heated, all liquid water heating systems use expansion tanks to account for this change in volume. correcting the answers listed above without deleting them Initially when a boiler is fired the water is heated and the steam starts to generate. During this time large amount of ebolution is taking place as the steam is trying to rise up through the water. This causes a swell in the water level and we actually sea a rise in the water level. when fired always waterlevel surges,it is seen practically
a boiler (a device for heating water) that is powered by gas
externally fired
wholly or partly surrounded by water
== == It is accomplished by adding an indirect fired water heater and controls.
there are two water level indicators usually mounted in front of boiler to ascertain the level of water inside the boiler am explain construction and working on next page
Effect of low water level in the boiler is rapid increase the temperature of the metal tubes, causing a collapse or rupture.

A gas fired boiler is a product used to heat your water for homes as well as swimming pools, they are very ifficient and save energy thus lowering your electric bill. There is a down side to having a gas fired boiler being as the costs of gases has gone up greatly it would be harder to keep a gas fired boiler going for a middle class person
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
I would look up your boiler specs or maybe contact that boiler brand and they would be able to help you because your question can be for many different situations.
the water goes up in vapor leaving behind the solids in the boiler.
