High-efficiency boilers are designed to maximize energy efficiency and minimize the consumption of natural resources, such as fuel and water. They are typically used in commercial applications, such as office buildings, restaurants, and commercial storefronts to provide heat, hot water, and steam for a variety of purposes.
There are several high-efficiency boilers, and they are majorly characterized by having an AFUE of 90% or higher, using most of the energy produced.
Below, we explore how improving your boiler’s efficiency can lead to significant cost savings and improved operational performance for your business.
The Importance of Boiler Efficiency
Boiler efficiency is a measure of how much of the energy used by the boiler is converted into usable heat. It is important because it determines the amount of fuel that is needed to produce a given amount of heat, and thus affects the cost of operating the boiler. If the boiler is not operating efficiently, it will use more fuel than necessary, leading to higher fuel costs.
Boilers with higher efficiency ratings consume less fuel, which translates to lower operating costs for businesses over time. High-efficiency boilers are designed to recover heat from flue gases, meaning they use significantly less energy than traditional boilers. This helps companies save money on their utility bills while also helping them reduce their environmental footprint.
Additionally, high-efficiency boilers require little space due to their compact design, making them ideal for tight spaces or locations where space is limited. They also have shorter start-up times, meaning they can be operational much faster than traditional models.

Benefits of High-Efficiency Boilers
There are several benefits to using high-efficiency boilers in commercial operations:
- Cost Savings: High-efficiency boilers can significantly reduce energy consumption and operating costs, as they use less fuel and water than traditional boilers. This can result in significant cost savings for businesses over time.
- Environmental Benefits: High-efficiency boilers produce fewer greenhouse gas emissions, which can help businesses reduce their carbon footprint and meet environmental regulations.
- Improved Performance: High-efficiency boilers are more reliable and efficient than traditional boilers, which can improve the performance of business operations.
- Flexibility: High-efficiency boilers can use a variety of fuels, including natural gas, propane, and oil, which gives businesses flexibility in terms of fuel choices and can help them take advantage of fluctuating fuel prices.
Expert Tips on How to Improve Boiler Efficiency
Below are some expert tips to help you improve the efficiency of your commercial boiler.
Monitor and Control Excess Air
When excess air is present in the boiler for any reason, it can reduce its efficiency by increasing heat loss, fuel consumption, and emissions. To maintain optimal efficiency, the boiler should be regularly calibrated at various firing levels.
Clean the Fireside
Regularly clean and inspect the fireside of the boiler tubes. Soot buildup can reduce heat transfer and increase fuel consumption. Maintaining clean boiler tubes can improve overall efficiency.
Clean the Waterside
Keep the waterside clean and free of leaks through diligent water treatment. Regular inspections and cleaning of mud legs or mud drums can improve heat transfer. To prevent scale buildup, address high water hardness, use proper chemicals, and blow down the boiler regularly. If left untreated, scale can reduce efficiency and cause the boiler to overheat, leading to costly repairs and leaks.
Ensure Proper Combustion
Ensuring proper combustion is essential. A high flue gas temperature reduces boiler efficiency by wasting fuel that could be used to heat water or generate steam. Installing a flue gas economizer can help reduce heat loss and increase efficiency by capturing wasted heat from the boiler’s flue gases and using it to pre-heat incoming cold water.
Upgrading insulation on pipes, tanks and other components can help retain heat and reduce energy losses associated with thermal leakage from the system’s surfaces. In fact, proper insulation can help reduce the surface temperature of the boiler and lower heat loss.
Use High-Efficiency Burners
High-efficiency burners are designed to use less fuel and generate more heat, which helps increase boiler efficiency.
Maintain the Ambient Temperature
The temperature of the air entering the boiler can significantly impact the efficiency of an industrial boiler. A 40 degree change in ambient temperature can result in a 1% or more change in efficiency. To achieve optimal efficiency, it is generally recommended to maintain an ambient temperature of 70-80° F.
Monitor Radiation and Convection Losses
This refers to the heat that is lost from the surface of the boiler while in use. Although you can’t stop it, the good news is that there are two most effective ways to reduce them. First, through proper insulation of the boiler and its associated piping and secondly by controlling the airflow over the surface of the boiler.
Reduce Excessive Water Levels
Maintaining proper water levels in the boiler can help reduce energy losses due to evaporation and ensure an efficient system.
Install Heat Recovery Systems
Heat recovery systems capture wasted heat from exhaust gases and transfer it back into the system, increasing overall efficiency.
Reduce Steam Usage
To improve boiler efficiency, consider insulating piping and tanks heated by steam, implementing a high-pressure condensate system, and regularly servicing the burner, boiler, and steam
Consider the Fuel Specification
Different fuels have different energy content, combustion characteristics, and emissions profiles, all of which can impact the efficiency of the boiler. Natural gas with a higher methane content and lower proportions of other gases, such as ethane, propane, butane, and pentane, is more efficient due to the lower hydrogen content.
