Magnetic System Filter Costs [Supply & Fit]

Why your heating system needs a magnetic system filter

Your heating system is made up of various metals. Over time, the metals degrade and circulate through radiators, towel rails, pipe work, and eventually the boiler. Not good.

A system filter is designed to catch any magnetic materials before they circulate through the boiler.

It helps to prevent blockages in pipework, radiators and crucial parts of your boiler (such as the heat exchanger and pump). These parts are extremely expensive to fix and a system filter is the best way to protect them.

Why a filter is not an alternative to inhibitor

Inhibitor works on breaking down non-magnetic materials in the system (copper for instance). Any build up is known as sludge. If there is excessive sludge build up, you’ll start to notice a range of problems. The most common being that certain radiators won’t be getting hot.

Many engineers will recommend a powerflush to combat this problem. There’s a big problem powerflushing. It puts an immense amount of stress on soldered joints (copper elbows etc) and on old systems can lead to leaks (more problems).

A hot flush or a manual flush is usually a much better option for old systems.

Inhibitor should be used in conjunction with a magnetic system filter.

Top 4 Magnetic System Filters [and what they cost]

After speaking to a few engineers (and checking best sellers from a local merchants) there are 4 filters that constantly come top of class.

Prices below are for 22mm filters. Some gas runs will be 28mm. 28mm filters are slightly more expensive.

Fernox TF1

For such a well-known brand, the Fernox TF1 filter is a great buy. Check out our Fernox TF1 Boiler Filter review here.

Worcester System Filter

If you have (or are having) a Worcester Bosch boiler installed, it’s wise to go with their own brand filter. It will increase the warranty offered by 1 year.

Instinct Eco-Mag

Comes with a 2 year warranty and is an excellent budget filter.

The MagnaClean range from Adey

Price: from £70 for the MagnaClean Micro, and £85-90 for the MaganaClean Professional Chemical Pack. We’ve created a guide to MagnaClean Filters here, and a review of the MagnaClean Professional 2 here.

Adey are one of the most well-known brands in this space. And their prices are reasonable. The Micro (small) filter is one of the cheapest on the market. It’s worth going for the larger filter in their range (Professional Chemical Pack) if budget allows.

Cost of installation

The total cost is going to be affected by your filter choice (and depends on whether you have a 22mm or 28mm gas run) as well as how accessible the installation area is.

Expect to pay around £90-125 for the installation with the total cost (including the filter and relevant chemicals) usually £200-250.

Filter maintenance

If you already have an annual boiler service, ask your engineer to include filter maintenance as part of the deal. All filters come apart quite easily and it’s a simple case of cleaning them out and checking for any wear and tear.

If you don’t already have an annual boiler service, it’s something that’s worthwhile and will help to protect your heating system. You can learn about the costs associated with a boiler service here.

If you need a Gas Safe engineer to assist with a boiler installation or magnetic system filter installation, call one of our guys at Heating Force.
