How long does a boiler last? March 21, 2022 One of the more costly purchases you'll make in your house is purchasing and installing a new boiler. When doing this, you will naturally want to know how much value you are receiving for your money from their boiler, which also makes you question how long it will last. What is the average lifespan of a boiler? The majority of boiler manufacturers and installers use a similar timeframe for when you should get a new boiler installed, which is typically every 15 years. If 15 years appears like a short period of time, it's probably because you grew up with a dependable old boiler that continued to provide hot water for the entire family, despite the number of times it has been repaired. What you're not considering is how effective it is. Boilers, especially modern ones, can theoretically last for more than 15 years however that's roughly about how long it takes for it to become so inefficient that buying a new one is more cost-effective and environmentally friendly. When you take a look inside a boiler, it consists of various parts and components such as pumps, valves and expansion vessels. All of these components, regardless of their quality, wear out at different times over the years. In addition to this, boilers alternate between hot and cold, which means it's continuously expanding and contracting, causing pipes and joints to become fatigued and stressed.
