Boiler efficiency tuning is all about fine-tuning the combustion process to get the most heat from every drop of fuel. You tweak the air-to-fuel ratio, clean the heat exchanger surfaces, and check that everything from the burner to the flue is working in harmony. It cuts energy waste, lowers operating costs, and reduces emissions without needing a full system overhaul.
