How To Improve The Longevity Of Your Boiler

How To Improve The Longevity Of Your Boiler

Gas boilers are heavy duty appliances which can last up to 15 years under normal use. However, the longevity of your boiler can be impacted by how you operate and maintain it. Treat your boiler well and you may get 15 years from it, treat it poorly and it may fail well before its 10th birthday.

Because replacing a boiler is so expensive, it is a good idea to be aware of the steps you can take to extend its lifespan. In this post, I’ll share some tips for prolonging the lifespan of your boiler and avoiding the unnecessary expense of premature replacement.

If you have any questions on boilers or would like to book a boiler repair, give Quantum Gas Engineering a call on 0203 633 2322.

Improving Your Boiler’s Lifespan

Use Central Heating Inhibitor
Corrosion is one of the most common causes of the premature boiler failure. The high temperatures and stresses affecting boiler metal can cause corrosion to spread throughout a heating system surprisingly quickly.

One of the simplest ways to reduce the risk of corrosion destroying your boiler prematurely is to use a corrosion inhibitor. It is a solution that slows down the rate of corrosion and protects the boiler against limescale buildup.

It can be applied directly to a radiator or via a water central storage tank. To use it:
1. Turn off the pump and boiler
2. Drain your radiators slightly, so the bleed pin can be opened without water spilling. Use a funnel to add corrosion inhibitor according to directions
3. If using a filling loop, drain a sufficient amount of water to make room for corrosion inhibitor.

If you don’t have time to add corrosion inhibitor, give Quantum Gas Engineering a call and we will take care of this important maintenance task for you.

Only Run The Boiler As Much As Necessary
The harder you work your boiler, the shorter its lifespan will be, so look for opportunities to reduce its workload.

If you are going to be out for the day or away for a weekend, lower the thermostat so it your appliance won’t be working hard to maintain a high temperature. You can also turn the thermostat down at night, as the building’s occupants will be in bed and under a layer of blankets.

Turn It On Over Summer
One of the reasons why homeowners love summer is that their boiler doesn’t need to be turned on, which reduces energy bills. However, you should still use your boiler periodically to prevent grit accumulating in the boiler pump.

All you need to do is turn the boiler on for a few minutes every 3-4 weeks. This will push any grit out of the pump. Set a reminder on your phone’s calendar to ensure this task is completed.

Understand Warning Signs Of Boiler Malfunction
Look for any signs that indicate your boiler is having issues, including:
• Not enough heat
• Water leakage
• Unusual noises (banging, clanking, gurgling, hissing, whistling)
• A metallic odour

Addressing these issues early on means you can avoid these problems worsening to the point where the boiler is irreparably damaged. It also ensures your home remains comfortable and your boiler is safe to use.

Bleed Your Radiators
Over the course of a year, small amounts of air can enter your radiators. There is a valve which is designed to remove this air, but it’s still common for a small amount of air to float to the top of each radiator. Unfortunately, having air in your system can impair its heating performance and cause the boiler to work harder — which shortens its lifespan. Having oxygen in your heating system can also encourage corrosion.

If the top of your radiators is cooler than the bottom, this usually means you have air trapped inside. Fortunately, getting rid of it is simple. All you need to do is use a radiator key to open the bleed valve near the top of the radiator. You will hear a hissing sound as air escapes the system. Have a cloth ready to absorb any water that escapes.

Install a magnetic filter
A magnetic filter consists of a plastic housing containing a powerful magnet. It is attached to the pipework of your heating system to remove any magnetic particles in the water. This action prevents the magnetic particles forming a sludge that clogs up boiler components, eventually shortening the lifespan of your boiler.

Have Your Boiler Regularly Serviced
Get a professional boiler maintenance technician to inspect your boiler at least once a year. They will be able to identify any minor issues before they worsen and cause severe damage to your appliance. Regular maintenance will also ensure that your boiler is running efficiently, which means a more comfortable home and lower energy bills.

Some of the maintenance tasks which should be performed include:
• Visual inspection
The boiler engineer will take a close look at the condition of the boiler, boiler casing, and boiler seals. They will look for any corrosion, leaks, and indications of boiler malfunction.
• Working pressure test
This test is used to confirm that the boiler’s pressure meets manufacturer’s recommendations.
• Gas rate test
The amount of gas reaching the boiler is checked to make sure it meets the manufacturer’s instructions
• Safety device check
All safety devices are checked and tested.
• Combustion analysis
A gas analyser is used to check that the rate of combustion matches the manufacturer’s instructions
• Controls
Al boiler controls are tested to ensure they are operational.
• Condensate trap is cleaned
If you have a condensing boiler, the engineer will clean the condensate trap
• Clean magnetic filter
If a Magnetic Filter has been fitted, the engineer will remove any gunk it has collected.
