What are the disadvantages of atmospheric pressure hot water boiler

2016-05-13

Atmospheric pressure hot water boiler is a boiler without pressure,it is widely applied in building heating because of small investment and floor area of it.However, it also has some shortcomings inevitably,this text will analyze that in the following aspects for your reference:

The system of atmospheric pressure hot water boiler is complicated

The heating of atmospheric pressure hot water boiler needs to add auxiliary machines,before entering the heating system,the hot water have to pass through many stages such as heat exchange,the whole system is more complex.Compared to the vacuum hot water boiler,the boiler proper of atmospheric pressure hot water boiler is cheaper than the vacuum hot water boiler’s,but,plus the price of auxiliary machineries,the atmospheric pressure hot water boiler is much expensive than vacuum hot water boiler.

The atmospheric pressure hot water boiler has a lower efficiency

The thermal efficiency of atmospheric pressure hot water boiler is generally only 82% or less,while the vacuum hot water boiler can reach 92%,the atmospheric pressure hot water boiler will produce scale in operation,so,its thermal efficiency will decrease year by year.

The atmospheric pressure hot water boiler have some restrictions on heating

The atmospheric pressure hot water boiler is only applicable to the heating of buildings below 7 layers,when used for more than 7 layers building heating, there are two options, one is increasing the circulating pump head to overcome the height of the buildings, another is increasing the heat exchanger and adopting the secondary water cycle scheme.

The service life of atmospheric pressure hot water boiler is short

In the above section,we have said that the atmospheric pressure hot water boiler will produce scale in operation,the scale will not only decrease the thermal efficiency of the system,but also shorten the service life the atmospheric pressure hot water boiler.

Through the above analysis,we can found that the vacuum hot water boiler has overcome many disadvantages of atmospheric pressure hot water boiler,such as,ZG vacuum hot water boilers have the advantages of long service life,high thermal efficiency,environmental protection,etc.The phase-change vacuum hot water boiler is more and more popular now,please browse its webpage or consult us for more details!

Fire tube steam boiler Advantage Introduction

2026-07-27

XHJ Boiler factory will introduction fire tube steam boiler advantage. Fire tube boiler may be used in steam or hot water applications. A fire-tube steam boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
