Are Magnetic Filters Worth It? Boiler filters explained

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

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?

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?

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.
