There are no two ways about it, at some point you will need to replace your boiler. However, there are several things you can do to increase your boiler life expectancy and keep your central heating system running smoothly for as long as possible.
Get an annual service
We can’t stress enough the importance of an annual service from a Gas Safe Registered (GSR) engineer. A qualified professional will be able to check your boiler is running efficiently and spot early signs of damage to avoid costly repairs.
Even if you believe your boiler is running smoothly, an annual service is a sure way to increase its life expectancy by keeping it that way. For Vaillant installed boilers, an annual service is necessary to maintain your guarantee after the first year.
As with many systems, boilers are not insusceptible to the effects of rust and corrosion over time. This then carries the potential for damage to the boiler. The best way to prevent this would be to request that your Vaillant engineer adds an inhibitor to your system. This is a protective coating that will form around the metals, preventing limescale build up and corrosion.
Please be aware, however, that an inhibitor is not a solution to limescale build up, but a preventative measure. If your system is suffering with corrosion, sludge and limescale, you’ll need your engineer to perform a powerflush (detailed below).
Prevent sludge build up
Sludge and debris can build up within the pipes of the central heating system over time, causing damage to your boiler. By installing a magnetic filter, a small component which sits within the pipework of the system, sludge will be safely filtered before it reaches the boiler.
A GSR engineer can install and clean a magnetic filter during your annual service, which will ultimately prolong the lifespan of your boiler.
If you have an older boiler, you may already be facing limescale build up or excessive sludge. This can cause blockages and corrosion to the central heating system, leading to a boiler breakdown. Quite simply, sludge build up can drastically reduce the lifespan of your boiler.
A Vaillant installer can resolve the issue with a power flush which involves pushing a specialist cleaning chemical through the heating system at high-pressure. This can take anywhere from 8 hours to 2 days, but it is necessary if you want to get the longest life possible span out of your boiler.
