When Should You Replace A Boiler Instead Of Repair?

The heating world is in a period of change and flux, with the potential for 2031’s central heating systems to look very different.

The government has previously proposed a staged transition away from gas boiler installation in favour of electric storage heaters, heat networks and hydrogen boilers for new build homes.

At present, whilst there are incentives for switching to renewable heat, there is no requirement to do so in the near future, which means that if you bought a boiler recently it should provide many years of comfortable, convenient heat.

However, if you are having issues or are worried about your boiler, here are some of the factors that will help you decide whether to repair or whether it is time to replace it.


The Problem With Age

Boilers last a long time, and whilst the average lifespan nears 10-15 years, they can potentially last for up to 25 years with care, regular maintenance and regular but not excessive use.

However, at around the ten-year mark, that efficiency can plummet quite dramatically, with a reduction of up to 30 per cent in their thermal efficiency, leading to more expensive heating bills.

Maintaining legacy boilers can also be increasingly expensive as parts and expertise get harder to come by, so if you are noticing that your boiler becomes less reliable over the years, it may be time to get a more efficient new model.


A Yellow Flame Or A Bad Smell

Whilst you often have a lot of time to mull over replacing a boiler if the issue is simply age, if you notice a distinct sour smell, or find that the bright blue flame has turned yellow, you may need to turn off your boiler and contact an engineer as soon as possible.

Both of these are a sign of carbon monoxide leaks or malfunctions, and if left on could put anyone in the home in danger.


Water Leak

Your boiler should never leak water. If it is, that is a sign of a broken valve or seal and can cause significant damage to your home or electrical systems if left unfixed.

When you spot a leak, switch the boiler off and get it checked.
