What is a boiler magnetic filter?
Magnetic filters are a relatively new product on the market for boilers. Boiler warranties have risen in popularity in the heating business.
A magnetic filter is a device that collects sludge that can accumulate in a heating system.
Rust particles that have corroded and come loose from inside pipes or radiators make up a large portion of the sludge. A magnetic filter consists of a huge magnet that attracts and filters these particles out of the system. This maintains the water moving through the central heating system and prevents obstructions. A magnetic filter is a device that collects sludge that can accumulate in a heating system.
So, what does the boiler magnetic filter do?
A magnetic filter is a simple product and that is undoubtedly a simple product, and this is undoubtedly one of its advantages. It has no moving parts and attracts metal trash from the heating circuit with a powerful magnet.
Steel radiators in a heating system corrode due to the presence of water and metal, resulting in minute metal particles that pile up and are referred to as sludge. This muck builds up in the radiators, limiting the amount of heat production and circulation.
Once a heating engineer has completed an annual service or inspection, the container may be isolated, the magnet removed, and the metal debris and ferrous particles easily removed and disposed of.
Why a central heating systems needs a magnetic filter
Corrosion and rust are common problems with iron and steel components in central heating systems. This creates a sludge that can clog various sections of the system, most notably the boiler heat exchanger, pump, and radiators.
Pipes made of cast iron used to be a few centimetres in diameter, but current piping is much narrower, making obstructions even more common. A clogged boiler will frequently overheat and shut off the system. An engineer may need to power flush your central heating system or rebuild the heat exchanger to clear a blockage, both of which are expensive jobs.
By catching any sludge before it reaches the boiler, a magnetic filter can help avoid these clogs and keep the system working smoothly. The debris is collected by a powerful magnet, which prevents it from damaging the boiler.
Are these magnetic filters worth it?
Every homeowner is familiar with the difficulties of maintaining a house boiler. The last thing you want is for your boiler to lose efficiency or shut down completely. However, it may appear that regulating the boiler is beyond our control at times — what is causing it to cease working without warning?
Because of the dust and debris that can accumulate in your pipes over time, this boiler nightmare can become a very real possibility. But, as a responsible homeowner, that doesn’t mean you have to sit there and accept that the disaster will occur. That’s why magnetic filters are so popular; they gather dirt and build-up before it clogs up your central heating system. You can ensure that your boiler continues to work normally and efficiently by using a magnetic boiler filter. What could be better?
You might be thinking to yourself right now, “Do I really need a magnetic filter?” It’s a reasonable question!
Boiler Magnetic filters for combi boilers are custom-fit to the pipes of your boiler. They remove debris from the running water that fills the pipes, ensuring that nothing builds up and disrupts the flow of water in the future. Here are a few reasons why adding a magnetic filter to your boiler system is a good idea:
Lowering Energy Costs:
Due to the ease with which water flows through your pipes, your home’s energy expenditures will decrease. When your pipes become clogged, your boiler must work extra hard to get the water from point A to point B.
Heat is essential for living comfortably throughout the chilly and damp autumn and winter months. Magnetic filters will offer a total efficient heating solution because your boiler is accountable for the reliability of your heating system.
Carbon Footprint Reduction:
By lowering the quantity of energy required by your boiler, you are also lowering the carbon footprint caused by energy demands. It’s an environmentally friendly option that everyone should think about.
Repairs are less likely to fail:
When your pipes become clogged, you’ll need an engineer to come in and solve the problem. This can be extremely costly, time-consuming, and aggravating. This will no longer be necessary thanks to boiler filters.
Boiler Life Expectancy:
You can reduce blockages on pricey equipment like your boiler’s heat exchanger or radiators by safeguarding and investing in the cleanliness of your heating system.
How can you install the magnetic filter?
If you’re getting a new boiler installed, your boiler engineer might suggest installing a magnetic filter as well. If a magnetic filter is fitted, certain boiler manufacturers may extend the warranty.
A magnetic filter can also be added to an existing system. The unit can be rather large, and it is installed near the boiler. This means that installing a magnetic filter isn’t always feasible – for example if the boiler is installed in a small cupboard.
Installation of magnetic filter on a boiler
Installing a magnetic boiler filter is quite a technical job and should only be undertaken by an experienced, gas safe registered, engineer. What follows are some basic details to help you understand what the engineer will need to do.
Isolate your boiler
Before the engineer starts they will need to make sure that the electricity is turned off and that they have something to cover up your flooring, make sure your boiler’s electricity is turned off and that you have something to cover up your flooring. This will prevent any debris or sludge water from spilling onto the floor from your boiler. Isolation valves should also be turned off.
Take off the lid
To remove the magnetic filter’s lid, you’ll probably have to unscrew it rather than pull it. Because your magnetic filter may be screwed shut for added security, you may need to use a little more force. Your installer may have additionally provided you a device to assist you in removing the lid. If you have any questions, please contact one of our engineers via live chat.
Remove the magnet
You’ll be able to spot the magnet and the filter once you’re inside. Sludge and grime will surround an unclean filter, making it obvious where you need to clean. Before you start cleaning, make sure the magnet is removed. Before you begin, you will be able to quickly slide out of position and place it somewhere safe.
Cleaning magnetic boiler filter thoroughly
Using a high-pressure hose to remove the rust and debris is the most effective approach for a cleaning magnetic boiler filter. Take extra precautions to properly clean everywhere, including the lid, to ensure that none of the debris is reintroduced into the system.
Replace the magnet and the lid
When finished, replace the cover as securely as possible and place the magnet back into the filter. Tighten the lid with your approved tool or a spanner to ensure it does not open up as new undesired material is deposited there. After that, replace the filter, reopen your valves, and turn on your boiler once more.
Advantages of a magnetic filter
There are numerous advantages to using magnetic filters in central heating systems. The biggest advantage is, of course, that it can assist your system in running more effectively and efficiently by removing junk and undesired waste elements. Your energy expenses will be substantially lower as a result of the efficiency than if your system was straining to perform properly. Furthermore, if sludge accumulates in the future, you’ll only have to clean the filter rather than the complete boiler system, making the process considerably easier.
When you consider the amount of damage you’ll avoid and the money you’ll save, installing a boiler magnetic filter is a no-brainer. You’ll be able to enjoy the following benefits once you have it:
- A system free of sludge and iron oxide deposits heating system
- Energy bill reductions on a yearly basis
- Longevity of the boiler
What is a magnetic filter on a boiler?
A boiler magnetic system filter catches metal deposits and rust particles that have accumulated in a heating system. Sludge build-up can cause cold radiators, unusual boiler noises, and even boiler leaks. Magnetic filters are often installed when a boiler is installed, although they can also be added to an existing system.
