how long should a boiler last

A boiler typically lasts between 15 to 20 years on average with proper maintenance. Some boilers, especially steam boilers, can last up to 30 years if they receive consistent and high-quality care. Gas boilers generally last around 10 to 15 years, while modern types like combi and condensing boilers tend to have lifespans of 15 to 20 years. Proper installation by a licensed professional and routine maintenance, including annual servicing, are crucial for maximizing boiler longevity and keeping it efficient.
