A Guide to Energy-Efficient Heating and Cooling

Inspect the flue piping for rusting and any disconnections or evidence of back drafting. Check all gas (or oil) connections, gas pressure, burner combustion, and heat exchanger. Improper burner operation can be caused by a dirty burner or a cracked heat exchanger—either can cause the equipment to operate less safely and efficiently.

Condensing boiler - Wikipedia

The lower the return temperature to the boiler the more likely it will be in condensing mode. If the return temperature is kept below approximately 55 °C (131 °F), the boiler should still be in condensing mode making low temperature applications such as radiant floors and even old cast iron radiators a good match for the technology.
