Instantanoous multipoint water heaters : These provide hot water to multiple taps or appliances at the same time. when the hot tap is turned on, a powerful gas burner in the heater ignites. The incoming cold water is heated as it flows through a large heat exchanger located above the gas burner. The heat ecchanger heats up a large volume of water very rapidly. They do not supply hot water to a cental heating system. Combination boiler : These provide hot water to the central heating system and instantanious hot water to the tap. when the hot water tap is turned on all the heat is diverted to the heat exchanger to give a rapid responce. hope this is of some use. austin mod 6
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.

the boiler.
Labor alone for a residential boiler would be around $800 while a water heater would be around $210-$300. These are typical rates for Connecticut anyway.
A hydronic heater works by using a boiler system to heat the water and then is pumped throughout the house in order to heat the specific area of a home.
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
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.
Boiler mountings are different fittings and devices which are necessary for the operation and safety of a boiler .e.g. pressure gauge, safety valves , steam stop valve etc Normally these device are mounted over boiler shell .Boiler Accessories are auxilary plants or parts required for steam boilers for their proper operation and to increase efficiency of the boiler .e.g.feed pumps, super heater , economiser etc
