A hot water heater is the storage tank of water that is responsible for the supply of hot water to the many fixtures in the house, such as showers and sinks. It does NOT supply heat for the home itself. There are two basic types of water heaters, one that runs on gas or some other fuel and one that runs on electric. A boiler on the other hand IS responsible for the heating of a home itself. Water or steam in a boiler reach much higher temperatures than the water in a hot water tank and therefore its used for heating and not drinking water or potable water. In a steam system for heating, pipes run throughout the house from the boiler carrying steam that eventually gives off its heat at the many radiators. In a hydronic system for heat, smaller pipes carry hot water to various baseboards around the house that release the heat using circulator pumps to push the water through and back to the boiler.
The water heater is a domestic device that is used to heat water for domestic purposes. A boiler on the other hand does not just heat the water but makes the water boil and turns it into steam.
A hot water boiler is a hot water heater that needs to have its parts replaced form time to time as they tend to wear out. Parts to hot water boiler can be purchased at home improvement stores like Home Depot and Lowe's. The boilers can also be purchased at a local plumbing supply store.
In a fire tube boiler, the water surrounds a set of tubes through which the fire and the products of combustion travel (as opposed to a water tube boiler, in which the water travels through the tubes, and the fire surrounds the tubes).The HVAC Veteran
What you meant by this question is uncertain. If you are asking about the definition then Boiler steam pressure is the pressure developed by a water steam boiler, else if you are asking about the Rated boiler steam pressure then it is the safe operating pressure a boiler can operate, else if you are asking about Maximum boiler steam pressure then it is the maximum pressure that a boiler can produce with out failure.
bleed is amount of steam output from turbine through pipe and exit from final stage of turbine . this bleed enter to feed water heater (low and high) and deaereator to increase unit efficiency or rather bleed is the amount of steam drained out of the steam turbine during the expansion of steam and this rejected heat energy is used to heat the feed water supplied to the boiler...........
wholly or partly surrounded by water
A combination boiler provide hot water to a central heating system whereas the multi-point water heater does not. The multi-point water heater provides hot water to multiple appliances or taps at the same time.
NONE a boiler is a boiler and a water heater is a water heaterSEE ASME section IV or the NBBI
new boiler and hot water heater
Domestic coil in boiler better than electric water heater.
The water heater has an electric heating element that is responsible to make the water hot if submerged to water. While the Calorifier is composed of steam coil where the steam from boiler passes through, is responsible to make the water hot if it get contact to the steam coil.
A furnace heats air; a boiler heats water. --The HVAC Veteran
== == It is accomplished by adding an indirect fired water heater and controls.
A burner is the part of the boiler that creates and controls the flame that heats the water. If you meant difference between a boiler and a furnace, a boiler makes hot water and a furnace makes hot air.
The difference between the two is that the Water tube boilers are safer and last much longer than the fire tube boiler. Their size is also larger and have a faster recovery time. However fire tube boilers have a low cost.

It's because "hot-water" is a compound adjective, modifying "heater". It's not for heating water, it's for heating a house with hot water. There are many types of heaters that heat water, but only a hot-water heater is used for providing heated water for domestic use. A hydronic boiler also heats water, but it's only for use in radiators.The name "Hot Water Heater" is completely wrong for any use. There is no need to heat hot water. IT has always been "water heater". The term hot water heater has just been used for years because people don't realize the difference. It has always been WATER HEATER.The first answer is jibberish and makes no practical sense at all.
we can increase boiler efficiency by recovering the heat which is being carried by flue gases.by incorporating different things like Economizer, Air pre-heater , Super-heater and feed-water heater, we can there ll be notable increase in efficiency of boiler.
