What Questions On Boiler Services Do JDF Maintenance Answer Weekly?
Hi, I’m John, founder of JDF Maintenance in Huddersfield. Over the years, I’ve worked on countless boilers, and one thing remains consistent: homeowners always have questions about their systems.
Trying to understand how boiler servicing works? Or troubleshooting a pressure issue? I’m here to help.
Every week, we get asked a range of questions about boilers and their maintenance. In this post, I’ll share the top questions we answer, explain these issues in plain terms, and give you advice you can rely on.
Does the boiler lose pressure when the heating is on?
Yes, it can. I do at times get calls about boilers losing pressure, and this is one of the most common problems homeowners face. A boiler may drop pressure while your heating is on for a variety of reasons, including a minor leak in the system or air trapped inside.
Typically, boilers are designed to operate between 1 and 1.5 bar pressure (you’ll spot this on the pressure gauge), but if the pressure dips below this, your heating may stop working efficiently—or altogether.
One common cause is expansion within the system as it heats up. However, if you notice a frequent or dramatic drop in pressure, I urge you to address it quickly. It might indicate a faulty pressure relief valve, a leak in the pipework, or even issues with the expansion vessel. These types of problems often go unnoticed until a boiler service is carried out.
The good news? If you’re unsure, we can help. Our servicing process includes checking your boiler pressure, identifying leaks, and resolving the issue before it worsens.
Does an electric boiler need servicing?
Absolutely, and this is a question I get far more frequently than you may expect! Many homeowners assume electric boilers don’t need servicing because they don’t use gas. However, electric boilers still require regular attention to ensure they’re performing safely and efficiently.
For instance, electric boilers have components like electrodes, heating elements, and pumps; all of which can wear down over time. Dust build-up, worn parts, or corroded elements can prevent the system from performing at its best, resulting in higher energy bills and potential breakdowns.
At JDF Maintenance, we believe prevention is better than cure. By servicing your electric boiler annually, we can check all the essential parts, clean out debris, and catch small problems before they lead to expensive repairs.
In such cases, it’s best to contact a Gas Safe engineer at JDF Maintenance on 07538 359 920 to investigate further.
Can a leaking radiator cause boiler pressure to drop?
Yes. If your radiator is leaking, it will almost certainly affect your boiler’s pressure. This is because water moves through a closed loop in your heating system—boiler, pipes, and radiators. When water escapes from a leak, less pressure builds within the system. This issue often results in radiators not heating properly and can make your boiler inefficient.
Leaks are usually caused by corrosion, faulty valves, or loose connections. If you’ve noticed damp spots on the floor, rust around your radiator connections, or that your radiator is underperforming, it’s worth giving us a call.
Fixing radiator leaks early prevents bigger system failures and keeps your boiler pressure steady.
When clients describe pressure drops to me, I always recommend they check for visible radiator leaks. Sometimes the damage is obvious, but other times, the leak may be hidden in pipework under the flooring. If it’s not immediately visible, I investigate during a service or call-out. From replacing faulty valves to patching worn connections, JDF Maintenance covers it all.
More Boiler Service Questions We Handle Regularly
Here are a few other questions I frequently hear from homeowners in Huddersfield:
How often should I get my boiler serviced?
I recommend servicing your boiler once a year. It ensures your system is safe, efficient, and won’t unexpectedly fail when the temperature drops. Plus, if your boiler is still under warranty, annual servicing is usually required to keep that warranty valid.
How can I tell if my boiler needs servicing?
Look for obvious signs: unusual noises, irregular cycling, unexpected leaks, and frequent pressure drops. Even if everything seems fine, it’s worth scheduling a yearly service to catch hidden issues before they develop into expensive repairs.
Why is my boiler making strange noises?
This is often a sign of kettling (caused by limescale build-up), trapped air, or loose internal components. Boilers shouldn’t make banging, clunking, or whistling noises. When they do, something isn’t right, and it’s better to deal with it early.
Does servicing my boiler improve energy efficiency?
Yes! During servicing, I check your boiler’s functionality, clean internal components, and ensure it’s running at optimum performance. A well-maintained boiler uses less energy, which means you save money on your heating bills.
