What are Magnetic System Filters? Here’s All You Need to Know

What are magnetic system filters

Over time, rust and debris can accumulate in the pipes of your central heating system. This can result in several issues, from boiler breakdowns to your heating system working less efficiently. To help ensure you don’t encounter similar problems in the future, consider using magnetic filters in your central heating system.

Magnetic Filters for Central Heating Systems

What exactly are magnetic filters? How do magnetic filters work? Would it be a good idea to invest in them? 

As water passes through the radiators and metal pipes in the central heating system, rust can form. Oftentimes, the rust breaks off and combines with other dirt and debris. When it does, it forms a mud-like substance often referred to as sludge. 

Sludge travels through the central heating system and often settles in certain places. This leads to a range of potential problems in the long run.

Case in point: When sludge accumulates at the bottom of the radiators, it causes cold spots. In other words, it hinders your central heating system from functioning like it should. 

Sludge can also clog up components within the boiler like the heat exchanger or the pump. When this results in a breakdown, you’ll likely need some parts of the appliance replaced. 

Essentially, magnetic filters are designed to catch the sludge before any problems related to it develops. The fact that they are magnetic also means they can be very effective at attracting and removing the corroded steel and iron that’s in the sludge. 

Some designs that come with a gravity filter are also effective at removing debris that are non ferrous.

In the event where your heating system is already blocked by heavy sludge, fitting a magnetic filter would no longer suffice. Power Flushing the system first is required.

Magnetic Filters: Answers to Frequently Ask Questions:

What are the benefits of using a magnetic filter?

Magnetic filters (also known as boiler filters) are fitted to the pipework of the boiler to extract any debris flowing through the pipes. However, there are other amazing benefits of using a magnetic filter. Some of the enticing benefits you can’t miss out on include:

  • It lowers the energy bills
  • It reduces carbon footprint
  • It makes the heating system work more efficiently
  • It helps ensure the longevity of your boiler
  • It reduces the risk of needing costly repairs in the future

What happens if sludge is not removed?

If sludge is not removed, it can have a significant impact on the efficiency and longevity of the heating system. Some of the red flags that indicate something Is wrong include:

  • Radiator is taking too long to heat up
  • Water from the taps is cloudy
  • You hear excessive noise from the radiators or boilers
  • Boiler shuts down regularly

Eventually, your boiler would no longer function as effectively when these issues are not addressed accordingly. Expect that energy bills will also rise. In worst case scenarios, you might need to replace the boilers.

Where is the magnetic filter fitted?

Magnetic filters are typically added to the boilers during the installation. At times, the filters can also be fitted onto existing systems. However, this is not always feasible and will depend on the location of the boiler. 

If you’re unsure if there’s space near your boiler where you can add a magnetic filter to the return pipe, get in touch with us. We’ll be able to assess if it is possible and if it can benefit your central heating system.

How is a magnetic filter cleaned?

Just like other components of the heating setup, a magnetic filter will require maintenance for it to carry its work properly. When we perform annual boiler service, we also clean your magnetic system filters to ensure they remain up and running.

What happens if you don’t have a magnetic filter?

A magnetic filter helps ensure there is no buildup of contaminants before a blockage occurs. Without a magnetic filter, sludge can accumulate and your system might require a powerflush. 

This process can be tedious and can take between 6-10 hours. In worst case scenarios, the system can get so damaged that it would require replacement.

Is a magnetic system filter worth it?

The answer is yes. When you have a new boiler, you’d want to be able to rely on it to work efficiently for many years, won’t you? A magnetic can help ensure your heating can serve you for many years to come.
