How much does a powerflush cost?
We often hear people saying that a Power Flush is expensive. Try asking Scottish Gas for a quote. I am confident that the price they quote will not be to your liking. Also in addition to us using a Kamco CF90 Power Flushing unit, the recognised best in the industry, we have invested in thermal imaging technology, which helps to identify problem blockages in central heating systems accurately.
Even a small system normally takes a few hours to powerflush. The specialist equipment takes time to set up and needs to be constantly manned. We offer a free no obligation quote for all powerflushes, but for most jobs we use the following formula.
Powerflush a system with up to 7 radiators is £350.00 (this is our minimum charge even for a smaller system)
Note. To avoid confusion, towel rails and hot water cylinders are counted as if they were a radiator.
For each additional radiator, towel rail, indirect hot water cylinder etc add £25.00
Example, a system with 7 radiators and 1 towel rail would cost £375.00 inc.
Example, a system with 8 radiators, a towel rail, and a hot water cylinder, would cost £425.00 inc.
In the event that for technical reasons, we offer an alternative quote to our standard rates, the quote is free with no obligation to accept.
What is a powerflush?
A powerflush is a means of removing sludge and other harmful products from central heating systems wiith the aid of chemicals and mechanical means with a powerflushing machine. We only use a Kamco CF90 Power Flushing machines,in conjunction with our Kamco Combi Mag filter. In our opinion Kamco machines are the best units in the industry. The end product being a clean system and boiler water wise. At the end of the job, the system must be treated with inhibitor, so as to avoid the system returning to its original condition.
Why do some central heating systems require a powerflush?
Boilers and central heating systems can suffer from sludge and contaminants restricting flow and efficiency. Common symptoms are cold spots in radiators, excessive requirements to bleed radiators, boiler kettling, and pump failure. Fluxes and jointing compounds used in installing central heating and pipework are highly corrosive. Boiler manufacturers will not repair problems or damage caused by sludge.
What can a powerflush achieve?
Like an athlete that gets rid of most of their fat and cholesterol, a system that gets rid of most of its sludge and contaminants will be more efficient, deliver better results, and be less likely to suffer pump and system breakdowns.
What cant a powerflush achieve?
Whilst a powerflush will remove most of the sludge and contaminants from a sysytem it cant achieve 100% removal. That said it gets it to a negligible level, that wont effect the system performance from sludge or contaminants. It cant however make a radiator heat up to its full potential if it is fed with undersized pipework. This is often the case when a large radiator is piped with microbore pipes. Even if the pipework and radiator are totally clear of sludge, the flow of water into and out of the radiator will be less than is required to heat up the whole radiator to is maximum potential.
Other common problems that are more due to system design, other than blockages and sludge are. Radiators with thermostatic control valves fitted at top entry level to a radiator. Whilst this is popular with elderly customers to allow adjustment of the thremostatic radiator valve without bending down, the hot water pumped into the radiator will naturally travel in a ski slope motion to the outlet valve at the opposite bottom side, leaving the missed area cold.
Twin entry valves, whilst not so common today are found in a lot of old systems. This is where both the pipes for the flow and return enter the same radiator valve at the same side on a radiator. A powerflush will not overcome these design flaws, and they must be rectified prior to carrying out a full system power flush.
Can a powerflush damage my system?
If a part of your system has a pinhole with rust holding it together, or a poorly made joint or fitting, then a powerflush may bring forward a leak that will happen in the long run. Customers should consider this possibility, but this has happened on only two occasions in all the 15 years we have been powerflushing. As we were on site at the time, the situations were handled with ease.
What if after having a powerflush, the original symptoms return?
We will re powerflush a system at no charge within 3 years of the powerflush, extended to 5 years if an Adey Magnaclean filter is fitted in conjunction with the power flush, providing the following conditions have been met. The central heating boiler must be serviced annually, within at least 13 months of each prior service. If the system is drained for whatever reason, when re filling the system either Kamco, Sentinel or Fernox inhibitor must be added to replace the inhibitors lost.
We recommend that new inhibitor is added to every system at every second year service to keep the system inhibitor potency at its maximum benefit. We cant offer any warranty to any system that has black truwell or microbore pipes in any part of the system.
For added protection, you could also have a Professional Adey Magnaclean Filter installed in your central heating system. This helps to filter out sludge and debri from entering your boiler. It is not however a substitute for a system requiring a powerflush. Once again, we offer a free no obligation quotation for Magnaclean filters.
Like a top of the range car manufacturer, you wouldnt expect to see the likes of BMW recommending the use of a supermarkets own branded oils or lubricants. Likewise our policy is only to use quality chemicals for cleaning and chemical inhibition protection, such a Kamco, Fernox, Sentinel etc.
