What’s the Most Efficient Boiler Type?

September 20, 2023

Boilers, which were first introduced in the late 18th century as kettle boilers perched atop blazing fireboxes, have seen significant advancements. Today, when considering a new boiler installation in your Wheeling, IL home, you’ll encounter a wide range of choices, including gas-fired, oil-fired, and electric boilers. To assist you in selecting the right option, let’s delve into boilers and their efficiency.

Gas Boilers

When it comes to efficiency, natural gas boilers shine. These heating systems are known for their low emissions and fuel efficiency. According to the U.S. Department of Energy (DOE), gas boilers with Energy Star ratings boast an annual fuel utilization efficiency (AFUE) of 90%, surpassing the mandated minimum by 8%. In simple terms, 90% of the fuel they consume is converted into heat energy, with only 10% lost as exhaust gases. However, a key limitation lies in the availability of natural gas infrastructure in certain areas.

Oil-Fired Boilers

The federally mandated minimum efficiency for oil-fired burners is set at 84%. However, modern oil-fired boiler models can achieve efficiency levels as high as 90%. This marks a significant improvement compared to a decade ago when oil-fired heating systems were 20% to 30% less efficient.

Electric Boilers

Electric boilers outperform even the most efficient gas-fired boilers with impressive AFUE ratings of 99% to 100%. They convert almost all the electricity into heat, generating zero exhaust. While electric boilers are environmentally friendly, they are less cost-effective compared to alternative options, impacting operational expenses and carbon footprint reduction.

Where Your Fuel Comes From

When searching for the most efficient boiler, the source of your fuel plays a crucial role, especially concerning the environmental impact. While electric boilers can efficiently convert fuel into heat energy, the carbon footprint of electricity production is higher compared to the sourcing of fuel oil or natural gas. Additionally, electricity can be more expensive in many regions. So, even if electric boilers save you money, they might not be the greener choice.
