I have a boiler that is over 20 years old, should I upgrade to a high-efficiency boiler?
Boiler technology has changed significantly in the past 10 years. Most older cast iron and sectional boilers are less than 80% efficient and don’t modulate to meet changing heating needs. A new high-efficiency boiler often has between 10-15 heating stages, and can modulate output to meet heating demand. Additionally, high-efficiency boilers can translate to significant energy savings. For example,
say your current boiler has an efficiency rating of 70% AFUE, and you pay about $1400 a year in fuel heating bills. If you upgrade to a 90% AFUE boiler, you can expect to save about 20% on your heating costs, or about $280 a year. Plus, by using less natural gas, you are reducing your carbon footprint!
