Heating System Filtration Unit
As water passes through the metal pipes and radiators 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. This sludge travels through your central heating system and can start to settle in certain places, leading to a range of potential problems.
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.
