How long do boilers last?

#Buying Guide

Boilers should last 10-15 years on average. If your boiler is approaching this timeframe, or has exceeded it, you may want to consider a new boiler that is likely to be more reliable, energy efficient and safe.

The lifetime of a boiler depends on whether it has been regularly serviced throughout its lifetime. Regular servicing and maintenance help protect the boiler and identify potential issues that may get worse over time and cause a malfunction.

How often should a boiler be serviced?

Boilers should be serviced every 12 months. A regular service check-up can help spot any potential issues with the boiler. A general check-up might see the boiler engineer maintain and keep the boiler clean of dust, rust or any other potentially harmful debris.

Your boiler should only ever be serviced by a Gas Safe Register engineer to ensure that the servicing is carried out in a thorough and safe manner by an experienced professional.

What does it cost to replace a boiler?

The cost of replacing a boiler depends on numerous factors - the size of property being heated, the level of work required to remove and place the old boiler, the manufacturer model and any other additional technology supplied with the boiler e.g. a smart thermostat.

Traditionally, it has been the case that a sales person has had to visit the property to provide a quote (much to the inconvenience of the property owner/dweller). BOXT's online Find-a-Boiler tool has revolutionised boiler replacement. BOXT customers can answer a few questions online or via the phone, and a start-of-the-art technology system can quote the best price for your property and heating needs. All costs are inclusive everything you need - installation, thermostat, boiler, delivery. In many instances BOXT can deliver and replace a boiler within 24 hours.

When should you replace a boiler?

There are many instances when it may be advisable to replace a boiler, including;

  • No heating - The most obvious reason to replace a boiler is because the boiler is no longer properly heating the heating system or water supply.
  • Winter weather - In the colder months we tend to see a higher rate of boiler failures and replacements. This can often be down to extreme over usage of the boiler as the temperature plummets. Furthermore, many property owners often turn their heating off at the end of winter and only turn it back on some 9 months later when it gets colder again (during which time a number of problems or faults could have occurred).
  • Soaring heating costs - Many older boiler models, especially those found in older properties, are energy inefficient. As such, they use a higher amount of energy to heat a property compared to newer boiler systems. Investing in a new energy-efficient boiler can help property owners reduce their costs over time.
  • If you've neglected regular servicing - Due to increasing heating energy costs, many property owners often skip or ignore servicing to cut costs. The downside of this is that the failure to spot potential issues or keep the boiler maintained can shorten the lifetime of the boiler. Sometimes the cost of repair can be more than simply replacing the boiler entirely.
