Why maintenance
What maintenance prevents.
Problems like a sticking low water cutoff, a fouled tube, or a drifting fuel-air ratio develop over time. A scheduled visit finds them while the fix is small and the plant is still running.
A tuned burner also burns less fuel and helps keep emissions inside your air permit limits, and a clean, documented boiler is ready when the inspector shows up.
