Yes, a 20-year-old boiler should definitely be replaced. Most boilers have a lifespan of 10-15 years, so yours is well past its expected life. At this age, you’re likely experiencing reduced efficiency, higher energy bills, and increased breakdown risk. Modern boilers are 90%+ efficient compared to older models at 60-70%, meaning you’ll save significantly on heating costs.
