What common problem do high-efficiency boilers face regarding their ignitions?

High-efficiency boilers are designed with advanced ignition systems that optimize fuel use and improve efficiency. However, these ignition systems can be complex and prone to malfunctions due to various factors, such as the presence of moisture, dirt, or wear over time. Unlike traditional systems, which may use simpler ignition methods, high-efficiency boilers often incorporate electronic ignition systems that rely on precise electrical components and sensors.

When these components fail or become malfunctioning, it can lead to ignition issues, such as failure to light or inconsistent performance. This can ultimately affect the overall efficiency of the boiler and lead to operational problems, making ignition system malfunctions a common concern in high-efficiency boilers. Recognizing and addressing these issues is crucial for maintaining proper heating performance and ensuring safety in HVAC systems.
