NEW BOILER VS USED BOILER, WHICH IS BETTER?

In order to save money, users may consider used boilers, as the cost performance of used boilers seems to be very high, but in fact, buying a boiler needs to be considered from many ways. The following are the common problems of used boilers.

The maintenance cost is high
On one hand, used boilers have high maintenance cost. On the other hand, safety is not guaranteed, boiler accident news is often visible. Most of the problems are caused by old boilers.
01
It is easy to be damaged in the process of assembly
The boiler has high requirements on the installation and disassembly. Once the used boiler does not operate according to the specification, it is easy to damage some parts and equipment, which directly affects the use.
02
No after-sales guarantee for used boilers
When dealing with used boiler, sellers usually sell it at a low price. You have to pay by yourself if it breaks down and needs maintenance.

03
High failure rate due to maintenance not in place
Many parts and equipment may have problems, such as thermometer, water level gauge, pressure gauge, safety valve, oil pump and so on.
