What is Powerflushing?
This process removes rust and debris that builds up in every heating system over time. Water, special chemicals and flushing equipment used by our experienced plumbing engineers remove this unwanted ‘sludge’ from the complete system. The machine used has techniques such as 3-way valves to make sure your system is expertly made as clean as possible. Yes we can clean microbore systems, please alert us when making your enquiry/requesting a quotation and see the FAQs.
Our speciality is to restore, repair and maintain central heating systems, heat exchangers and associated pipework and radiators – including breakdowns, blockages, kettling and other failures. The engineers use a cleaning process with a water treatment called ‘powerflushing’ that removes contaminants and particles that prevent your system from working or reduce its efficiency. Our power flush machine is used in place of your circulating pump and uses pressure and heat to clear your system. After the process is complete we use a corrosion inhibitor to make sure that your system stays clean and efficient for as long as possible. Your heating system should be more reliable and efficient, less noisy and with fewer ‘cold spots’ after our treatment process.
Before and after our treatment process, our Engineers will inspect and report on your heating system and provide you with:
• A verbal and written report on findings and work carried out
• A certificate confirming the treatment and status of your system – useful if you are thinking of renting or selling your property
• A 5 year guarantee against blockages after our full service
• A clean and tidy area where we have been working
Our Promise:
• A competitive package price vs leading energy suppliers
• A visit time to suit you
Why might I need Powerflushing?
• Your pump may have failed completely or fails to circulate efficiently – this leads to poor heating of radiators and other issues with the boiler and thermostat such as overheating
• You may have blockages in the system which means that some radiators are not working or have ‘cold spots’
• Your system may be noisy with popping, hissing or banging – this is likely due to blockages, or even worse, steam trying to escape which can be dangerous
• Rust in your system, especially with an old boiler, or even with a relatively new boiler, can come from the radiators which are usually mild steel. This builds up as unwanted sludge
Finally, we will advise you on future maintenance of your system with corrosion inhibitor to help keep it running at its best capacity. Contact us now for a competitive quotation designed for your system and a service timing to suit you.
