Is it common for high-efficiency boilers to have problems with the cabinet?

High-efficiency boilers are designed to operate with increased energy efficiency by utilizing heat exchange processes that can condense water vapor in flue gases. However, due to the operation at lower temperatures and the condensation of moisture, these boilers can experience specific issues related to their cabinet.

For example, moisture from condensation can lead to corrosion or rust within the cabinet if proper drainage and materials are not considered during installation. Additionally, the design of high-efficiency boilers often requires tighter seals and more sophisticated components which, if not properly maintained, can also lead to problems.

Factors such as inadequate ventilation, maintenance neglect, or installation errors can compound these issues, making it not uncommon for the cabinet of high-efficiency boilers to suffer from various problems. This highlights the importance of regular inspections and preventive maintenance to ensure the longevity and functionality of these systems.
