Boiler log records are probably the single best method to ensure a boiler is getting proper maintenance. The boiler logs provide a continuous record of the boiler's operation, maintenance and testing. Because operating conditions change slowly over time, a log is the best way to detect significant changes that might otherwise go unnoticed.
