Central Heating Power Flushing

For over two decades, A Brassett has been a trusted provider of Central Heating Power Flushing services. But what exactly is power flushing, and why is it essential for central heating systems? Let's explore the significance of power flushing and how A Brassett has been serving London residents with top-notch services.

Power flushing is a process designed to give your central heating system a thorough internal clean, resulting in improved performance and potential savings on gas bills. Whenever a new central heating system is installed, it is crucial to undergo pre-commission cleansing in compliance with BS:7593 and Benchmark standards. This process eliminates flux residues, excess jointing compounds, mineral oil, and other contaminants that may be present in the system after installation. These impurities can adversely affect the system's performance and even lead to component failure if left untreated.

Moreover, when installing new boilers into older systems, it is vital to remove all sludge from the system. Failure to do so could cause the sludge to accumulate in the new boiler and lead to premature failure. In areas with hard water, existing systems may have accumulated limescale and corrosion deposits in the heat exchanger, which can decrease boiler efficiency by over 5%. Power flushing is the most effective and efficient method for thoroughly cleansing a central heating system.

The power flushing process involves creating a powerful flow of fresh water under controlled conditions to remove debris from the system. By connecting the power flushing unit to the heating circuit in place of the system pump, boiler, or radiator, the circuit can be thoroughly cleaned of limescale and corrosion debris. When paired with a Fernox cleanser, a typical power flush can be completed within 3-4 hours.

A Brassett offers an extensive in-home service network, catering to housing associations, letting agencies, private landlords, and individual homeowners. The team is committed to providing timely assistance, aiming to send an engineer to your location within 48 hours of your call. With various service time slots available, including 7.30am to 9.30am, 8am to 2pm, and 12pm to 4pm, A Brassett ensures convenience and professionalism throughout the repair process.

In the diagram below, we illustrate a typical heating system and highlight potential problem areas that power flushing can effectively address. It is particularly crucial to ensure your system is clean before installing modern high-efficiency boilers. Following installation, the system should be treated with an inhibitor during commissioning, adhering to the approved standard known as Benchmark to validate the manufacturer's guarantee.

Problem Areas: - Blockage in radiator valve: Leading to incorrect operation and no flow in the radiator. - Pump seizure and failure: Black oxide sludge increases shaft and bearing wear, causing pumps to stick or fail. - Cold spots: Build-up of black sludge sediment restricts flow and reduces heat in radiators. - Top of radiator is cold during operation: This could indicate air or hydrogen build-up due to electrolytic corrosion (caution required). - Pinhole leak: Potential water damage. - Black sludge in underfloor pipework: Reduced flow or blockage in pipework. - Scale (limescale/iron oxides) in the boiler: Leading to reduced efficiency, increased emissions, higher fuel bills, and boiler noise.

With A Brassett's expert power flushing services, you can ensure the optimal performance and longevity of your central heating system, backed by the professionalism and satisfaction of their team.
