What is a powerflush?
A power flush is the process of cleaning out the debris from within your central heating system.
What are the benefits of a powerflush?
Flushing your central heating system can significantly improve long term protection.
- Heat will be distributed more evenly throughout your home
- Improved carbon footprint through better energy efficiency
- Saving money on your fuel bills
- Better performance and more reliable heating system
- Extended boiler and heating system life
Over time rust, sludge, and other debris build up in your central heating system and cause the system to become inefficient. In hard water areas the system has the added problem of limescale build up, just like kettles and this in turn accumulates within the system too.
The build of debris can impact significantly on the performance of your system, costing you money as you boiler works harder whilst still being unable to heat up your home.
When should I get a powerflush?
- If your boiler is noisy
- If your central heating pump is excessively noisy
- If your heating system takes a long time to get hot
- If some rooms in your home are colder than others
- If any of your radiators have cold spots
- If your radiators need frequent bleeding
- If you notice dirty water when bleeding
- If you are considering replacing your old boiler
You might benefit from a powerflush if you have any cold spots on your radiators, if you notice any dirty water whenever you bleed them, if your boiler is making loud banging noises or the central heating pump is making excessive noise.
If you are considering replacing your old boiler we recommend a powerflush. This is a precautionary measure to ensure that any debris in the heating system is removed so it doesn’t cause any damage to your new condensing boiler.
How does a powerflush work?
Our highly trained engineers will connect an industrial powerflush unit together with a powerful magnetic filter to your central heating system. This is achieved by removing a single radiator and connecting to existing pipework. Alternatively we may remove the central pump, allowing a complete system flush without the need to remove any additional radiators.
The system is flushed by sending high flow water mixed with chemicals containing strong cleaning agents through the system so that water flows at high pressure through the system and back through the magnetic filter which collects any iron oxide, sludge, rust and debris.
We measure the surface temperature of the radiators with infrared thermometers to detect any cold rust spots. We can then target the radiator individually with high-pressure flow to vibrate the radiators vigorously and removing any internal rust spots.
It could be the case that your entire system doesn’t require powerflushing. If only a few radiators are cold it might be possible to remove the culprit radiators and flush them separately. Call us now and speak to one of our expert advisors who can help diagnose your problem and provide the right solution.
How much does a powerflush cost?
To get the most out of your home heating system it’s important that it runs efficiently at all times. Although a powerflush can seem like an expensive commitment it can save money on fuel bills and should ideally be carried out with a full boiler service.
We have different tiers depending on your central heating system.
- Up to 4 radiators: £390 (£468 inc VAT)
- 10 radiators: £450 (£540 inc VAT)
- per additional radiator thereafter up to 30 radiators: £30 (£36 inc VAT)
How long does a powerflush take?
We generally arrive at 8 am in the morning to carry out your powerflush and depending on the number of radiators in your house the entire procedure can take up to a full day. We’ll provide you with a rough estimate of how long we should be on site at the time of booking.You can call us directly to book a convenient time for our engineer to visit or you might prefer to use our online booking facility to book your own dedicated time slot. We’ll call you straight back to confirm your appointment and take all the necessary details.
- We’ll use an infrared laser thermometer to detect any cold spots in your radiators
- Open the radiator valves (carefully protecting your floors from any leaks
- Disconnect your circulatory pump so that we can connect our powerflush machine
- We’ll also connect to the water supply (usually an outside tap)
- Using a clean magnetic filter attached to the system to collect debris
- Fill the powerflush machine with chemical that circulates through the system
- We also use a precision made radiator agitator device to dislodge sludge, blockages and hardened deposits from inside radiator
- Dislodged rust is carried through the cleaning system and collected in the magnetic filter chamber
- The dirty water is collected and dispersed with appropriately
- We then use the infra red thermometer once again to check the radiators
- We also use a TDS (Total Dissolved Solids) meter to test the levels between mains water and system water to ensure correct dosing of inhibitor or flushing chemical into the system.
- We also use a PH meter to tests the strength of chemicals after neutralisation to ensure that system water is neutral after the power flush.
- We can also show you the accumulated rust on the magnetic filet to give you an indication of how valuable a powerflush is in prolonging the life of your central heating system.
- Then we add alkaline neutralising crystals to the system as well as some scale and corrosion inhibitor before balancing your radiators and checking one last time with our infra red thermometer.
- At the end of the power flushing procedure we issue a certificate to confirm the procedure has been successfully carried out.
