Magnetic Filter: Maximizing Heating System Performance and Extending Longevity

Heating systems play a crucial role in maintaining comfort within a property, but they are susceptible to various issues caused by sludge. Thankfully, boiler magnetic filters offer an effective solution by utilizing powerful magnets to attract and capture these contaminants, preventing them from circulating and causing problems. However, it is important to note that the boiler filter can become clogged over time, hindering its functionality. Regular cleaning and maintenance are necessary to ensure optimal performance. In this article, we will delve deeper into how the boiler magnetic filter function and discuss essential steps for keeping them in pristine condition.

How does a magnetic filter work?

The primary function of magnetic filters is to safeguard the boiler by preventing the accumulation of sludge, dirt, and debris in the heat exchanger. The presence of sludge in heating systems can lead to cold spots on radiators and inefficient heat distribution throughout the property. Magnetic filters effectively combat these issues through a simple yet highly effective mechanism.

The formation of steel sludge, a major concern for central heating, occurs when steel comes into contact with water and oxygen. This chemical reaction results in corrosion and the subsequent buildup of sludge, which then begins to circulate within the system. While chemical and power flushes can remove sludge during maintenance procedures, a magnetic filter excels in day-to-day maintenance by efficiently capturing and removing sludge and other unwanted substances. By employing magnets designed to attract these contaminants, the most need a magnetic filter can ensure that the whole central heating system operates at peak efficiency, ultimately reducing energy bills and extending the lifespan of the boilers and radiators.

8 Steps How Proper Clean Your Magnetic Filter on a Boiler

1. Safety Precautions:

Before starting to build up any maintenance procedures, ensure that the boiler is turned off and cooled down to a safe temperature.

2. Shut Off Valves:

Locate the shut-off valves on the magnetic filter and close them to isolate the magnet and magnetic filter from the rest of the boiler. This prevents water from flowing through the large magnet and filter during the cleaning process.

3. Drain the System:

Open the drain valve on the pipe with the magnetic filter to release the water flowing under the pressure. This step is essential to prevent water leakage from pipes and minimize the risk of spills during the cleaning process.

4. Remove the Magnetic Filter cap:

Depending on the installation of the magnetic filter it may be positioned near the boiler or elsewhere on the pipework. Carefully remove the boiler filter top cover. You should have a spanner supplied by the existing system manufacturer. Following the manufacturer’s instructions or any specific guidelines provided by the heating system manufacturer.

5. Inspect and Clean the Filter:

Examine the boiler filter for any signs of damage or excessive sludge accumulation. On the bottom of the magnetic filter open the valve and drain down the black water from the filter. Use a soft brush or a cloth to gently remove any visible sludge from the surface of the hard water area of the filter.

This is the time when you can fill an inhibitor to build up your filter.

7. Reinstall the Magnetic Filter:

After flushing and cleaning, reinstall the magnetic filter top back into its housing, making sure it is securely installed and properly tightened. Ensure that any seals or gaskets are in place and tightened correctly.

8. Open the Valves and Test:

Open the shut-off valve to restore water flow to the heating system. Check for any leaks around the seals and ensure that the whole system itself is functioning properly.
