When people are shopping for heating systems to install in a new house, one of the points of comparison they make between different models is their estimated service life. In this column, the boiler has a large advantage over the gas furnace, electric furnace, or heat pump. A boiler usually outlasts any of these other heaters.
But a boiler can’t run forever. Once you’ve gotten a good number of years of warmth from your home’s boiler and it’s more than repaid its initial investment, you should consider having it replaced. There are a number of ways to tell that you have a boiler that’s ready for a retirement; we recommend you call on HVAC professionals to help you with the choice if you’re uncertain if your boiler can go for a few more years or not.
