No one likes to hear that they have to replace their boilers. As soon as this happens, most people assume it’s going to cost them a fortune. Unfortunately, you can’t put off replacing your boiler, as they can become hazardous if they don’t function properly. 

Luckily, there are ways around boiler replacements when you choose to trust the right supplier. Not all faulty boilers require an entire replacement. This guide will help you to better understand how often you should replace your boiler. 

The Different Types of Boiler & How Long They Last

There are several factors that affect how often a boiler should be replaced, one of which is the type of boiler you have. Here’s a breakdown:

Combination (Combi) Boilers

Combi boilers are becoming very popular in the UK as they provide both heating and hot water from a single, compact unit, making them ideal for spaces requiring minimal surface area usage. They also heat water directly from the mains, so there’s no need for a separate hot water tank, saving on installation time and costs. If maintained well, the typical lifespan of a combi boiler is 10-15 years, though exceptional care can make them last up to 20 years.

Electric Boilers 

Electric boilers generally require less maintenance than gas or oil boilers, as they have fewer moving parts and don’t require annual servicing. However, it’s still important to inspect them periodically to ensure they operate safely and efficiently. They’re a type of heating system that uses electricity to heat water, rather than gas or oil, meaning they run off the home’s mains to heat the elements. 

One of the main benefits of this type of boiler is that it does not produce carbon monoxide as it does not run off any kind of fuel. The usual lifespan of these boilers is between 10 and 15 years.

Biomass Boilers 

Biomass boilers are home and water heating systems that utilise organic materials such as wood pellets, chips, or logs to generate heat. They are a popular choice for those looking to reduce their carbon footprint and are considered more sustainable than fossil fuel boilers as they use renewable resources and have a smaller environmental impact. 

These systems can last between 10 – 15 years with a regular maintenance plan although they can also last up to 20 years when properly taken care of. 

Oil Boilers

Oil Boilers work similarly to gas boilers, igniting the fuel in a combustion chamber and using a heat exchanger to warm up cold water from the mains or a tank. Oil boilers require a separate storage tank on the property to hold fuel, while gas and electric boilers are connected directly to the gas or electric mains. 

Oil boilers are often used in homes that are not connected to the gas grid mains or that run off-grid. Oil boilers, too, can last up to 20 years.

When Should You Replace Your Boiler?

There are some signs that present themselves when it’s time to replace your boiler. Some of these include: 

  • The age of your boiler: If your boiler is approaching or older than 15 years, you should, at the very least, get it inspected by a gas-safe certified professional. They may advise you to replace you to replace your boiler.
  • You hear odd noises: If you hear sounds that closely resemble banging, gurgling, or clunking, then it may mean there are mechanical issues inside the boiler. This is often a sign replacement is needed.
  • You notice leaks: A leaking boiler can be problematic as it may increase water bills. Some boilers can also leak harmful gases, which can be extremely dangerous. Ensure you call in a professional as soon as you notice any leaks.
  • Your boiler turns off on its own: These are signs of internal issues that may mean your boiler needs to be replaced.
  • You notice increased energy bills: A faulty boiler increases energy bills are its declining efficiency, thermostat/valve issues, pilot light problems, and general wear and tear – all of which cause the boiler to consume more gas or electricity to heat the home. Replacing an old, inefficient boiler is often the best solution to reduce high energy costs.

How Often Should You Get Your Boiler serviced?

Your service frequency also depends on the type of your boiler, but it’s often best to get our boiler unit serviced at least once a year. For a more detailed explanation, Gas and oil boilers should be serviced at least once a year by a qualified professional. This is recommended by manufacturers and often required to keep the warranty valid. 

Electric boilers require less frequent servicing, but it’s still recommended to have them serviced at least once a year to ensure optimal performance and safety. Property owners should ensure they get their boiler serviced once a year.
