Magnetic Filters for Heating Systems: How They Work and What they Do

The pipes in your central heating system are prone to rust and debris building in them over time. This can affect the quality of heating and also give rise to several issues, such as boiler breakdowns. Luckily, prevention is possible and you can consider using magnetic filters in your central heating system to help prevent such issues from occurring and extend the lifespan of your heating system.

But what are magnetic filters and how do they work? We will discuss these here. If you want a quality magnetic filter for heating system, you can always connect with us for the best deal.

What is a Magnetic Filter?

A central heating system consists of metal pipes and radiators and when water passes through them, there’s a high chance of forming rust. This rust then breaks and combine with other dirt and debris to form a mud-like substance called sludge. This sludge then travels through your central heating system and can settle in some places leading to various issues.

For example, when sludge builds up at the bottom of radiators, it can form what is known as cold spots that restrict your heating system to function efficiently. It can also clog components such as the pump or heat exchanger of your boiler. This can, in turn, result in breakdowns.

Magnetic filters are designed to catch the sludge and thus prevent these problems from occurring. They are magnetic, meaning they can attract and remove the corroded iron and steel material from the sludge. Some designs include a gravity filter that also removes non-ferrous debris.

When Do You Need a Magnetic Filter?

Some signals indicate you should consider using a magnetic filter for your heating system. For example, if your radiators stay cool at the bottom but hot at the top, means there can be a sludge build-up and you need to install a magnetic filter.

Also, boilers making strange gurgling or banging noises can indicate a sludge build-up. Pump leaks and failures can also point to the same issue.

If you do not take care of these issues, the efficiency of your heating system will gradually fall and you’ll end up paying more in energy bills. Your carbon footprint too will increase. You may also need to repair your boilers and it affects the lifespan of your heating system overall.

So, if your heating system is showing such issues, or you want to prevent such issues from occurring, the best thing to do will be to install a magnetic filter.

Installing Magnetic Filters

Magnetic filters are fitted to the pipes that return water to the boilers. They can be installed when installing the heating system, in boilers. Or, sometimes, they can be fixed to existing systems. However, depending upon the location of the boiler fitting a magnetic filter into an existing system may not always be feasible.

If you’re not sure if a magnetic filter can be fixed to the existing system you can connect with a heating expert for solutions.

This was all about a magnetic filter for heating system. Just remember, like every other part of your heating system, you need to maintain your magnetic filters as well so that it can continue working efficiently. It is recommended to clean this piece of equipment every year by some professionals to make your heating system run efficiently.
