Adding a magnetic filter to your central heating system can prevent build-ups of sludge, extending your boiler's lifespan and saving you money. Over time, debris and rust can build up in the pipes and radiators of your central heating system. This can lead to a range of issues, from making your heating system less efficient to causing boiler breakdowns. To help prevent these problems from arising, you should be considering using a magnetic filter in your central heating system.

As water passes through the metal pipes, radiators and valves in your central heating system, rust can form. This rust can then break off and, when combined with other debris and dirt, it can form a mud-like substance often referred to as sludge or magnetite. This sludge travels through your central heating system and can start to settle in certain places, leading to a range of potential problems.

For example, when it builds up at the bottom of radiators, it can cause cold spots, meaning your heating won’t function as efficiently as it should. The substance can also start to clog up components within your boiler, such as the pump or heat exchanger. This could result in breakdowns and mean you need to have parts of the appliance replaced.

Magnetic filters are designed to catch this sludge and therefore prevent these problems. The fact that they are magnetic means they are effective at attracting and removing the corroded iron and steel material within the sludge. Designs that include a gravity filter also remove non-ferrous debris.

Bear in mind that if your heating system is heavily blocked by sludge, fitting a magnetic filter won’t be enough to clean it. You’ll need to powerflush your system first.

We can supply and fit a magnetic filter to your system for only £100 if you have booked a powerflush.

We can supply and fit a magnetic filter to your system for only £200 as a stand alone job.
