What is the most expensive part of a boiler?

Gas boilers can have varying costs for their components, which depend on factors such as brand, model, and age. Generally, the most expensive part of a gas boiler is the heat exchanger, as it plays the main role in transferring heat from burning gas to circulating water for heating purposes.

Heat exchangers can become damaged over time, leading to failures that are expensive to replace. Additionally, other costly parts of a gas boiler may include the burner, control module, and central heating pump.

When your boiler loses heat and hot water, you can tell your boiler has failed you. However, there are other causes of a broken boiler that should be brought to your attention. Please contact us if one of the below issues is causing your boiler to malfunction.

  • Loud clanking or banging noises.
  • Frequent water pressure changes, tend to be too high.
  • Excessive or high condensation in your room
  • Increased gas usage (you may notice your gas bill or smart meter telling you that you spend more on gas than you usually do). This shows that your boiler isn’t working efficiently as it should be.

If you are witnessing any of these signs, turn off your boiler immediately.

  • If your boiler is displaying an error code you should write it down. This code can be useful to us or an engineer as we try and fix your boiler.
  • Please make sure your boiler is correctly supplied with water, electricity and gas. Check if a gas appliance you already have like an oven or hob is working at your home. If not, you most likely have a gas supply problem and it can be fixed if you contact your gas transportation network.

  1. First, check your thermostat to see if it is set to the correct temperature. If it is, then the problem may be with the boiler itself.
