How can you prolong the life of your boiler?

Checking up on your radiators

The air might become trapped inside your radiators during the functioning of your boiler. While it may appear harmless at first, it can hinder your boiler from operating at maximum efficiency. This is because trapped air inside your radiator causes chilly patches to form over its surface, which the hot water cannot reach.

You can follow these simple steps:

  • Turn on your heating system to see which radiators need to be bled.
  • Turn off the heat and wait for it to cool down.
  • Using the radiator key, turn on the bleed valve.
  • Close the valve once the hissing has stopped and water has emerged from the hole.
  • Restart the heating system.

Avoid overworking your boiler

Each boiler’s design is based on the need to produce constant hot water whenever it is required. Keeping this in mind, try to avoid using the boiler until necessary because it will help to maintain the expectancy of a boiler. If the pressure is adjusted too high, it will be subjected to a great deal of wear and tear over time. Above all, keep in mind that a boiler chosen with the correct guidance and support will have already taken into account available space and should have no trouble meeting hot water demands for a long time period.

Setting your boiler off in summer

It may sound a bit odd but turning off your boiler in the summers is one of its kind of a way to extend the life of your boiler. Turning off the boiler can turn on the chances of your boiler working longer than expected. Allowing your boiler to operate during the summer allows you to:

  • Assist in preventing sludge from forming in any given area.
  • Break down the muck that has already built up in your system.
  • Boost the flow of water inside your pipes.

Many modern boilers feature a summer setting that you may activate to ensure that your heating is only used during specific seasons. During this time, though, it’s still worth running the boiler now and then to keep it going.

Keeping your pipes insulated

By ensuring that these pipes are lagged, you can minimise boiler leaking and guarantee that you are properly insulated over the winter. This is also a regular occurrence with condensate pipes, which play a vital role in the heat recycling process.


The majority of people believe that their boiler should be replaced every ten years but if you will keep taking boiler services then it will increase the expectancy of a boiler. After all, that’s when productivity begins to dwindle. Machines, on the other hand, aren’t like perishable foods. They can outlast their “expiration date” if properly cared for. Instead of deciding on a replacement based on its age, look for these telltale symptoms of a faulty boiler:

  • Gas/fuel bills that are too high
  • The boiler and radiator are making a lot of noise.
  • Replacement parts are difficult to come by.
  • Breakdowns are common.
  • Inadequately heat your home and water

You may be due for a replacement when these signs become commonplace and you have your engineer on fast dial.
