15 WAYS TO INCREASE BOILER EFFICIENCY
One of the easiest ways for a business to reduce operating expenses is to increase boiler efficiency. A great place to start lowering your bills is to look at how recently you performed boiler maintenance and how efficient your commercial boiler is. The boiler draws in cool air, heats it up, and sends it out the stack. A lower stack gas temperature is ideal because the higher the temperature, the more energy leaves with the flue gas

HOW FEED WATER AFFECTS BOILER OPERATIONS
It’s important to understand how your boiler feed water system functions, especially when trying to extend the useful life of your equipment. Low-quality boiler feed water contains impurities and gases that can damage the whole system. This will lead to a reduction in efficiency and, even worse, boiler leaks or system leaks.

MAXIMIZE CONDENSING BOILER EFFICIENCY
A condensing boiler is a water heating system designed to retrieve energy normally released from the boiler stack as waste. Latent heat is a significant source of energy. This means condensing boilers can potentially hold an efficiency rating of up to 98% in some cases. By comparison, a traditional boiler is generally between 70-85%.
