When to replace a boiler system?

When people by heating systems to install in a new home, one of the points of comparison they make between the different models is their estimated useful life. In this column, the boiler has a great advantage over the gas oven, electric oven or heat pump. A boiler usually survives one of these other heaters.

But a boiler cannot work forever. Once you’ve received a good number of years of heat from your home’s boiler, and it’s more than paid back its initial investment, you should consider replacing it. There are several ways to know that you have a boiler ready to change it;

Base system age

The first question to ask when it comes to replacing the boiler is: “How long has the boiler been in service?” The average life of a boiler is between 10 and 15. We recommend that you replace a boiler over 15 years of age. At that age, any boiler has a greater risk of breakdowns, excessive repairs and energy consumption that is not worth keeping. It may appear that the boiler is still operating the way you want it. That can change in a flash. If your condensing boiler has standard maintenance, you can expect it to run for around 15 years. Cast iron boilers can last much longer, even up to 50 years, with proper boiler maintenance. If your condensing boiler is nearly 15 years old or your cast iron boiler has been on the way for 50 years, it might be time to think about an upgrade.

When To Replace A Boiler System


One of the big warning signs of a boiler ready to be demolished is rust and other types of corrosion. Modern manufacturers design boiler systems to resist corrosion for many years. As long as the boilers are serviced annually by the professionals, corrosion shouldn’t have a chance to resist. But leaks and broken valves that let air in or the reaction between the burners and the heat exchanger can eventually create corrosion. When this happens, it is best to have a new boiler installed.


A boiler that has worn out too much with age is subject to the development of leaks in the valves and connection points. The moment you see a build up of water around the boiler, call repairs to see what’s causing it. The technician can provide an informed opinion on whether to have a replacement system or the possibility of repairing the heater.

High energy bills

If your energy bills are on the rise or if you need to intervene on your boiler more frequently, it could be because it’s time to buy a new, more efficient boiler. A boiler that raises the cost of heating your home every winter is not the one you want to keep around. It is often possible to correct small price jumps at the beginning of the system’s life. But if the boiler has already passed that 15-year milestone, the rising costs mean the system has deteriorated too much. Getting started with a new high-efficiency boiler system helps you get started saving money right away. This provides you with a heater that should be trouble-free for many years.


If some areas of your home are too cold or too hot, and you can’t control them properly or find them comfortable, it could be that your boiler is no longer effective, and you may need to look into upgrade options.
