If your boiler is not efficient enough, this can cause your gas bills to skyrocket and your home to not heat up as well as it should.

In addition to this, if your boiler is working inefficiently over a long period, this can even cause the boiler to break completely. Not only is this expensive, but it will take time to fix too.

If the efficiency of your boiler is a concern, there are a few things you can do to improve this. While some of these tips may only be minor adjustments, you will be surprised by how much they can help improve your gas bills. These will also improve how eco-friendly your boiler system is.

Bleeding Your Radiators

One of the main reasons your home may not be heating up as well as it should is due to your radiators needing to be bled.

It is fairly easy to find out if your radiators need to be bled. If they remain cold at the top while being warm at the bottom when the heating is turned on, they need to be bled.

Bleeding a radiator consists of removing the excess air found in the radiator. Once removed your boiler system will be significantly more efficient, and the radiators should be warm throughout.

This will help to reduce the cost of your energy bills and improve the heat efficiency of your boiler system.

Increasing The Boiler Pressure

The pressure within your boiler system can drop without you realising. If the pressure is too low, the efficiency is decreased.

You should check your boiler regularly to ensure that it has a good amount of pressure. A good boiler pressure will sit in the green zone of the gauge. If the indicator is below this, your boiler does not have the correct pressure.

If the pressure is too low, your boiler will not heat up efficiently and you may find some of your radiators are not as warm as they should be. This can be caused if you have a small leak in your boiler system, or if the radiators have just been bled.

To increase the pressure of your boiler, you will need to turn the pressure valve to allow more pressure into the boiler until it reached the green zone. This will help to improve efficiency and reduce your gas bills.

Cleaning Your Boiler

This is something that you may not have considered before, but keeping your boiler clean can improve its efficiency.

When you are cleaning your house, you want to ensure that you are dusting your boiler and its surroundings to keep it dust-free. This will stop the pipes from becoming clogged and dirty, which will improve its overall efficiency.

When you are cleaning the boiler, you should only clean its outside, the inside of the boiler can be cleaned when it is serviced. This should only be cleaned by a professional.


If your boiler system is losing a lot of its heat from its pipes, this is not only more expensive when it comes to bills, but it is not very efficient or eco-friendly.

When a lot of heat is lost from the pipes, your boiler has to work harder to compensate for this. This is why it is important to insulate your heating pipes where possible.

You can do this by using foam tubes made for this purpose. This will help to prevent heat from escaping and will keep your pipes warm and insulated. This is fairly easy to resolve and will make a big difference to the overall efficiency of your boiler.

Regular Service and Maintenance

It is important to regularly check your boiler and your boiler system to ensure it is working efficiently. The sooner you resolve boiler issues, the better this is for efficiency and overall costs.
