Benefits of power flushing

and why it's essential for keeping your heating system in top condition.

Maintaining a clean and efficient heating system is crucial for the comfort and well-being of your home. Over time, dirt, sludge, rust, and debris can accumulate within your boiler and radiators, reducing their performance and potentially causing expensive repairs. Power flushing is a highly effective method of cleaning your heating system, offering a range of benefits that can significantly improve its efficiency and longevity.

Enhance Energy Efficiency

One of the primary benefits of power flushing is the significant improvement in energy efficiency. Over time, dirt, debris and sludge can build up within the system, reducing the flow of water and impeding the heat transfer process. This can lead to uneven heating, cold spots in radiators, and an increased workload for the boiler. Power flushing removes these blockages, allowing the water to circulate freely and maximizing heat output. As a result, your heating system operates more efficiently, saving energy and reducing your heating bills.

Increase Lifespan of the Boiler

Regular power flushing can help extend the lifespan of your boiler. Accumulated debris, sludge, and limescale can cause corrosion and damage to internal components, leading to breakdowns and costly repairs. By flushing out these contaminants, power flushing prevents corrosion, reduces stress on the boiler, and ensures it operates at optimal performance levels. As a result, your boiler's lifespan is prolonged, saving you from premature replacement expenses.

Improve Heating Performance

Over time, the accumulation of sludge and debris in your radiators can restrict the flow of hot water, resulting in cold spots and an uneven distribution of heat. Power flushing effectively removes these obstructions, allowing hot water to circulate freely throughout the system. As a result, your radiators heat up faster and provide consistent warmth throughout your home. Improved heating performance means greater comfort and a more enjoyable living environment for you and your family.

Quieter Operation

If you've noticed strange noises coming from your heating system, such as banging, knocking, or gurgling sounds, it's likely due to the presence of trapped air and debris within the pipes and radiators. Power flushing eliminates air pockets and dislodges trapped debris, significantly reducing these annoying noises. Enjoy a quieter and more peaceful home environment once your heating system has undergone power flushing.

Enhance Reliability

Power flushing can greatly enhance the reliability of your heating system. By removing blockages and reducing the risk of component damage, power flushing helps to prevent system failures and breakdowns. You can have peace of mind knowing that your heating system is running smoothly, especially during the cold winter months when you rely on it the most.


Regular maintenance and cleaning guarantee that your heating system working safely and efficiently. If your heating system is not cleaned regularly, it is at higher risk of breaking down and costing you more money.

Power Flushing Process


We ask you about all your heating system details, for eg. the type of heating, boiler model, number of radiators, etc. After that, we will book a suitable date for you. Upon arrival, our specialist will survey your central heating system and select the best place to connect the dedicated power flush equipment.


The process of power flushing does not take much time and it can usually be carried out in as little as a day on most residential properties. However, larger systems and commercial premises may take longer to power flush.


After connecting the power flush machine to your heating system, a solution of water, chemicals and rust inhibitors is introduced to the system.


The solution loosens the black iron oxide sludge and lime scale and pushes it through the system, as the solution passes through the system a special magnetic filter captures the iron oxide and limescale, removing it from the system and allowing only liquid to pass back into the central heating system.


Once all iron oxide sludge and lime scale have been removed from the system the power flush is complete, allowing water to once again freely circulate around the central heating system.
The chemicals and inhibitors are left in the heating system to help protect your system from future build-ups.

The lads from IntHome are the top notch. I had a brilliant experience with flushing service at my home in Blanchardstown. Jarek honestly was excellent at explaining the issues and great conversation on other matters. My radiators were working perfectly once finished.

After a month with no heating in the flat and almost a week after the last attempted repair by another company left us with no hot water, we received Rafal and his coworker's visit. The main goal was to flush the circuit to try and remove a blockage that prevented filling it and the boiler from being functional. Lads are dogged and did a great job of the power flush of blocked pipe and seven radiators.

We used IntHome to clean our heating system and I found them punctual, polite and knowledgeable about the process. After seeing what came out of the system I’m glad We did! Jarek the engineer was very professional, tidy and friendly. We would recommend this company to all our friends and family.

A magnetic filter is a central heating system filtration unit, capable of capturing virtually 100% of the Magnetite within a system.

Magnetite is the official name of system sludge, it’s made up from Iron Oxide the result of a chemical reaction between the different metals and air ingress into the heating system.

The main benefit is an improvement in system efficiency. System Sludge creates cold spots within your radiators, which in turn reduces the efficiency and thermal output of the heating device. Removing these cold spots, the system will return back to its right purpose.

The magnetic filter works so well because the steel sludge is attracted to the magnet. Corroded steel debris passes through the system and gets caught in the filter, allowing the newly cleaned water to continue through your pipes. The purpose is designed to remove sludge from your heating system.

Magnetic filters protect and maintain both new and existing central heating systems. Even a small build-up of iron oxide in a modern efficiency boiler will result in substantial efficiency loss and fuel wastage.

Magnetic filter is designed to maintain and protect all domestic central heating systems from the damaging effects of iron oxide sludge build up. This protection lasts throughout the lifetime of the boiler and helps to reduce central heating energy bills by up to 6%.

Magnetic Filter installation cost €199
