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.

Hot Flush

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.

Scale Reducer

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.

Regular Servicing

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.
