If you’re not sure whether you should replacing your boiler rather than fixing it, this guide is going to help.
We’re going to cover exactly how long boilers last, how to prolong the life of your boiler, when you should be repairing it, and when it’s time for a replacement.
Want to jump right ahead and get your boiler replaced? You can get competitive prices from BOXT, a company part owned by Bosch – they offer excellent deals on Worcester boilers, complete with a 10-year warranty.
How Long Does a Boilers Last?
Typically, you’d expect the lifespan of a boiler to be in the region of 10-15 years. This can be less for unreliable brands, and those with incredibly short warranties. This lifespan applies to all fuel types such as oil, lpg and gas, as well as all types including combi, system and regular boilers.
How Long Should A Worcester Boiler Last?
Worcester Bosch boilers tend to last between 12-15 years. However, we’ve seen Worcester Bosch boilers that are 22+ years old and still going strong.
When Should You Repair Your Boiler?
If your boiler is less than 5-years old, and there are only 1-2 parts needing repairs costing £300 or less, the economic option, is to repair it rather than replace it.
When Should You Replace Your Boiler?
When your boiler is over 10-years old, out of warranty and you’re facing bills of over £500, we’d suggest going for a replacement. You can get prices for a replacement here.
How much does it cost to replace a boiler?
Combi boiler installations typically start around £1,800 but can be much more expensive for large properties. You can get fixed prices on screen here, or read our full guide to boiler installation here.
Making Your Boiler Last Longer
There are ways to ensure your boiler lasts as long as possible. As we’ve mentioned, we’d typically expect boilers to last in the 10-15 year range, but this isn’t going to happen unless you follow the steps below.
Buy Boilers With A Long Warranty
If you’ve read any of our boiler reviews, you’ll know we don’t recommend boilers with less than 10-years in warranty. The warranty on offer gives an indication of what that brand thinks of their boilers quality, but it also gives a timeframe where you’re not eligible for expensive repair bills.
Currently, the best deals on boilers with long warranties come from BOXT. You’ll be able to get a 10-year warranty on a Worcester Bosch boiler. And, you can get prices on screen within 90 seconds, without inputting any personal details.
If you do get your boiler replaced, it’s worth having a hot flush. This involves cleaning out your whole heating system of heating sludge, which is a build-up of rust that breaks off radiators, towel rails, pipe work and boiler parts. Heating sludge can cause damage, which can sometimes be terminal.
Magnetic System Filter
Alongside a boiler installation, you’ll want a magnetic system filter. This will collect the heating sludge mentioned above. And, your boiler service company can clean it out with each annual service. If it’s full, it won’t be able to remove sludge from your system.
For those in hard water areas, we’d also suggest having a scale reducer fitted. This combats limescale, which helps your boiler to operate at optimum efficiency.
Central Heating Inhibitor
After a hot flush with chemicals, and a new boiler installation, you’ll want your boiler company to dose the system with central heating inhibitor. This allows central heating sludge to be broken down into manageable chunks. Your magnetic system filter can then remove these chunks of heating sludge from your heating system.
Regularly servicing will allow your Gas Safe engineer to spot problems with your boiler, before they’re terminal, saving you money on expensive repair bills.
More to the point, most boiler manufacturers require proof that annual services have been completed by a Gas Safe engineer, otherwise they won’t honour their warranty.
