Can a boiler explode?

While historically, boilers would over-pressurise and explode with alarming regularity, modern boilers are manufactured to be able to withstand excessive pressure, and can typically handle an operating pressure of 20 PSI. When pressures increase beyond this level, the boiler can fail, which can lead to an explosion.

Can a boiler last 40 years?

Age: Condensing boilers haven’t been on the market for a long time and therefore it is hard to predict their longevity. Some of these boilers can last even up to 50 years or longer, but even with decent annual maintenance, their efficiencies are much lower than today’s cast iron boilers.
