The answer to 'how to maintain boiler' is to perform regular maintenance and inspections to keep your boiler running efficiently and safely. This includes tasks like checking the pressure, cleaning the burners, and inspecting for any leaks or damage. It's important to follow the manufacturer's recommended maintenance schedule and address any issues promptly to prevent more serious problems down the line.
Boiler maintenance should be done at least once a year, ideally before the heating season begins. You'll want to have a professional HVAC technician perform a full inspection and tune-up to ensure everything is working properly. They can also provide guidance on how to do basic maintenance tasks yourself between professional visits.
