High Efficiency and Standard Efficiency Boilers Boiler

High Efficiency and Standard Efficiency Boilers. Efficiency in boilers isn't about how quickly the boiler heats your home; it's about how much of the heat energy from gas you pay for is used to heat your home and how much is wasted in the flue gases. And it's not just about energy costs. It takes a certain amount of heat to keep our homes warm.

Boiler Efficiency: Introduction and Methods of Calculation

Combustion Efficiency. The combustion efficiency of a boiler is the indication of burners ability to burn fuel. The two parameters which determine the burner efficiency are unburnt fuel quantities in exhaust and excess oxygen levels in the exhaust. As the amount of excess air is increased, the quantity of unburnt fuel in the exhaust decreases.
