When to replace your boiler?

16 December 2021


Property owners and facility managers frequently wait until a boiler is entirely broken down before replacing it. To make matters worse, these types of failures occur when there is a genuine need for warmth, and because the failure is unanticipated, emergency funds are rarely available to address the issue.

It is not enjoyable to be forced to spend unforeseen funds to replace a boiler that has suffered preventable damages. Implementing a regular maintenance and inspection schedule with a skilled plumber is the first step for owners to avoid this. Boiler system examinations should be done at least once a year.


What is the average life of a boiler?

The average lifespan of a boiler is between 10 and 15 years. However, if your current one is nearing the end of its useful life, it may be time to replace it before it forces you to do so. Not only should a good boiler heat your home efficiently, but it should also do so for a long period.

If you have recently purchased a new boiler, you won’t have to worry about finding a replacement boiler for several years. Modern boilers are significantly more efficient than older versions, especially those installed more than ten years ago. These boilers date from a time when technology and environmental concerns were vastly different. 

On the other hand, if your boiler was installed less than 5 years ago, it is likely to be far more efficient. You can keep these boiler systems working smoothly for a longer period of time with the proper maintenance.

How to extend the life of your boiler?

The majority of manufacturers say that their boilers will last 10 to 15 years. This does not imply that your boiler will survive indefinitely. If it does, it may not perform as well as it did when you originally purchased it. The following procedures will help your heating system last longer and stay in good working order:

  • Select a high-quality combi boiler: When looking for a new boiler, there are various manufacturers to choose from, each with a different price range. However, not all boilers are made equal. To save money, you might be tempted to buy the lowest quality model available. In the long run, this may be a bad decision as you may end up with a boiler that is not up to standards.
  • Make an appointment for your boiler to be serviced once a year: Having your boiler inspected by a professional at least once a year is recommended. Many manufacturers may void your boiler’s warranty if you do not have it serviced annually. A yearly boiler service will help extend the life of your boiler in addition to renewing the warranty.
  • Always choose qualified professionals: Many manufacturer warranties become void if they are not serviced regularly. Warranties are also nullified if someone who is not a qualified professional checks your boiler. Avoid chasing after cheaper alternatives because a professional is the proper person for the job. Installing, repairing, and servicing your boiler requires certifications.
  • Monitor your central heating: Central heating faults are usually easy to spot because it stops heating as efficiently. You should monitor your central heating system closely and take note of any strange changes. This can help you spot any problems early on and schedule an appointment with a plumber before a breakdown occurs.


When should I replace my boiler?

Even if your boiler is still working after 10-15 years, it is a good idea to start thinking about replacing it because its efficiency will have deteriorated. A new boiler could be able to supply you with improved quality of heating and hot water. You may even save money on your energy expenses by installing a new boiler that is more energy-efficient.


6 signs it’s time to replace your boiler 

What are signs it’s time to replace your boiler? 

  1. Your boiler’s age
  2. Corrosion
  3. Costly maintenance
  4. Reduced efficiency
  5. Unusual noises
  6. Leaks

1. Your Boiler’s Age

How long has the boiler been in service? This is one of the first questions you should ask yourself to determine when it’s time to replace your boiler. While most people are aware that their boiler will not last forever, many nonetheless handle it as if it will. Most boilers will last anywhere from 10 to 15 years on average. If your boiler is over 20 years old and in need of major repairs, it is probably time to replace it.

2. Corrosion

When you detect corrosion on your boiler, it’s one of the most obvious signals that it’s time to replace it. While most manufacturers design boiler systems to withstand corrosion for several years, air leaks and faulty valves can and will cause corrosion. The reaction between the heat exchanger and the burners can potentially produce corrosion.

Standard annual maintenance from professionals, on the other hand, can immediately detect these types of issues. These checks should identify the sources of corrosion before it becomes a problem. However, if your heating system is corroded, it’s usually advisable to replace it.

3. Costly Maintenance

To guarantee that your residential or industrial boiler continues to function effectively year after year, it needs to be repaired and maintained regularly. However, if the expense of keeping your boiler running continues to rise year after year, you may want to consider replacing the boiler. At some point, replacing the boiler with new equipment is a wiser investment than continuing to pay for the old boiler’s escalating repair costs.

 4. Reduced Efficiency

Even if your boiler continues to suit your demands, it may not do so as efficiently as it did when you first purchased it. When your boiler requires more energy than it did when it was first installed, it may be time to consider replacing it with a newer, more energy-efficient type. Today’s technology is far more advanced, so upgrading to a newer model will help you save money and energy.

5. Unusual Noises

Boiler systems are not designed to be silent. However, there are several noises that your boiler should never make. For example, if your boiler makes a clanging noise, a loud pounding noise, or any other form of startling noise, this is not a good indicator and may suggest that it’s time to repair your boiler. These noises could be the result of a pressure problem, a leak, or a blockage. Strange noises should be investigated by a certified plumber.

6. Leaks

It’s best to contact an experienced professional if you find your boiler is leaking. Leaks aren’t always an indication that your boiler isn’t working properly, but they could indicate that a disaster is on the way. If your boiler has grown excessively worn down with age, leaks at connection points and valves are more prone to occur. Your heating system may be nearing the end of its life if it leaks or needs more make-up water. You can reduce the risk of costly flooding, property damage, or catastrophic boiler explosion by replacing the defective boiler.

What are the main types of boilers? 

The main types of boiler found on the market are:

  • Electric boilers
  • Condensing boilers
  • Oil boilers
  • Biomass boilers

Electric Boilers

Electric boilers are a popular alternative. These work by drawing energy from the main house supply and using it to heat the boiler’s components. Water is heated as it passes over the elements, allowing it to circulate through the central heating system. These types of boilers do not burn fuel or emit fumes or gases like carbon monoxide so this is a safer form of boiler system. Electric boilers are easy to operate and maintain, and they can be installed quickly because they don’t require flume or fuel storage.

Condensing Boilers

A condensing boiler circulates hot gas through a central chamber, which heats water, and then circulates the remaining heat back into the heating system to warm water in a second chamber. There are a number of varieties of condensing boilers, with the combi-boiler being one of the most popular

A combi-boiler combines a hot water heater and a cold water tank into one unit, making boiler installation easier. A combi-boiler also offers a constant supply of hot water in the home, eliminating the need to wait for the tank to warm up.

Oil Boilers

Oil boilers are similar to gas boilers in that they use oil to generate hot water. The water is then pumped via the house’s radiators. Because the oil must be delivered, these boilers can be significantly more expensive than other types of boiler systems.

Biomass Boilers

A biomass boiler heats water by burning wood pellets, logs, or chips. They’re suitable for those whose homes aren’t connected to the main gas supply, just like oil boilers. A wood stove is a type of biomass heating equipment. Biomass heaters are often larger than gas or oil boilers, and installing one would necessitate the installation of a chimney, as well as obtaining planning approval.


Find out when your boiler needs to be replaced

Even if your boiler isn’t on the verge of collapsing, upgrading to a newer, more efficient system can provide plenty of advantages. Most importantly, you have control over the situation and can plan for change, which is preferable than dealing with a full-fledged emergency in the dead of winter.
