Disadvantages of Atmospheric Pressure Hot Water Boiler
Atmospheric pressure hot water boiler is boiler working no-pressure. because of small investment and floor area of it, Atmospheric pressure hot water boiler is widely applied in building heating. However, it also has some shortcomings inevitably, this text will analyze that in the following aspects for your reference:
System of atmospheric pressure hot water boiler is complicated
The heating of atmospheric pressure hot water boiler needs to add auxiliary machineries,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.
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.
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.
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, Romiter 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!
