How to Improve the Efficiency of Your Boiler Heating System

Boilers are an efficient way of heating a large space. They will only maintain their high level of efficiency if they are properly maintained and if the rest of the building is also energy-efficient. Learn how an annual New York City boiler inspection could identify some of the most common factors that reduce boiler efficiency.

Excess Air in the Combustion Chamber

The amount of air flowing into the boiler’s combustion chamber needs to be calibrated at multiple firing temperatures. This can be checked as a part of a routine boiler inspection. It can also be done when the boiler is serviced. When too much air flows through, the air absorbs some of the heat generated by the combustion process. That heat is diverted from the building, resulting in a drop in efficiency.

High Flue Gas Temperature

Another inefficiency that can be detected by a boiler inspection is a high flue gas temperature. If too much heat is being lost to the waste gases dispensed by the flue, it means that less of the heat is being used to generate steam and heat the building. An economizer could be installed to capture some of the heat and reduce the loss of efficiency.

Losses From Convection and Radiation

Air blowing across the boiler could result in a loss of efficiency because of convection. Air drafts in the surrounding area could decrease heating efficiency because of radiation of indoor heat to the outdoors. Sealing air drafts could lessen some of these losses. Controlling air movement in the area where the boiler system is located may also help. Some of these losses are inevitable, but they can be managed. An energy audit could identify the locations of air drafts.
