The water in a hot water heating system remains in the lines at all times. The water in the heating unit lines heats and cools slowly, resulting in an even rate of heat production. When pressure is lost in the steam heating system, steam leaves the heating units resulting in a more rapid loss of heat than in a hot water heating system. In addition, the steam heating system has a longer recovery time in producing heat after the boiler is shut down. Boilers are used in both hot water heating
Below is a typical steam boiler diagram for dummy's to understand with name of each component or boiler part. First of all you should understand that there are many types and nomenclature of boilers. For example steam boiler, combi boiler, vaillant boiler, hot water boiler, gas boiler, electric boiler, weil mclain boiler, condensing boiler, oil boiler, burnham boilers, central boiler, lochinvar boiler, water tube boiler, system boiler, central heating boilers, buderus boiler, bosch boilers
The diagram below shows the general layout of an unvented hot water system: Instantaneous hot water heating systems This method involves using gas or electricity to heat the water to a useable temperature without the need to store the water. The electric versions use a coiled heating element to heat …
Conventional, Combi and System boiler systems explained
10. Mixing valves are recommended on all tanks if hot water temperature is above 119oF. 11. Expansion tank must be rated for use with potable water. 12. Use either indirect/tank sensor or system/pipe sensor mounted on common return to the boiler. 13. Aquastat or system/pipe sensor connects to DHW sensor input on boiler.

Hot water system zoning can also reduce energy cost because hot water heat zones which are not needed can be shut down thereby reducing boiler runtime to provide hot water heat for those specific zones. Zoning a hot water boiler system can be done by using these zone valves and separate thermostats for each zone.
