Before the cold season arrives where ever you may reside, preparing your boiler with regular preventative maintenance for the heating season is critical to efficient and safe operation. The frequency of common boiler issues, such as inefficient burner operation, cracking, dry fire, and pilot failure, may be reduced with proper attention. Their dependability and efficiency is contingent upon these tasks being performed both properly and regularly. With the rising costs of fuel and equipment it pays to be proactive in caring for your boiler. Following are some important tasks you and your qualified technician can perform to aid in safe and successful heating boiler start-up and operation.
