a power flush is where chemicals are circulated around the system using a machine which pumps it round at speak and under slight pressure. this is best used when the system is in a bad condition where radiators are partially blocked etc. a chemical flush is where a cleaning chemical is added and it is circulated under the control of the system itself. I would use this as a system maintenance program where the heating system was circulating ok but the water was dirty.

A power flush is using a powerful machine that runs high pressure water with chemicals and sometimes high temperatures to clear out any stubborn sludge buildup. The machine flushes the system many times to clear the sludge from the system. A chemical flush doesn’t use a machine to flush the chemicals around the system, it uses the boiler. This system is usually combined with a Magna cleanse which is a strong magnet that traps the sludge stopping it from getting caught up in the system when draining.

A powerflush uses a machine which incorporates a pump, you remove the boiler from the system, add chemicals and sometimes heat, some machines have a immersion, you can push the water round your heating system at high pressure and flow and also reverse the flow to unsettle any stubborn dirt. Power flushing is expensive but sometimes is required. On a new boiler install if the system is really dirty then a powerflush could be required. A chemical flush is just that, you add chemicals to the system and then flush it out this is more than often followed by a mains flush. This will normally be performed when a new boiler is fitted and where a powerflush isn’t required.

A power flush is also a chemical flush but much better. (power flush also uses chemicals) The power flush is normally set up by removing the c/h pump and attaching the machine to it. The machine is able to change the direction off flow coursing the the build up off sludge to be distributed and removed from the system.

Several hundred pounds is the financial difference. I would always look at putting a chemical cleaner in the system first, this is often sufficient to remove the problems. A reputable plumber would suggest trying the cheaper chemical option first and if that was not satisfactory, the would take the cost of the chemical clean away from the price of the power flush.

A Chemical Flush is like the Powerslush's baby brother. A Powerflush used a powerful pump to send water and a chemical clear around your heating system to dislodge and take away all of the dirt / rust and sludge that has accumulated. A chemical Flush essentially does the same thing on a less powerful / small scale

we try add a chemical a few days before doing a powerflush & ask customer to use as much as they can to help powerflush. when powerflushing , we have adey magnets on pipes coming back onto flushing machine to attract the sludge , which speeds up powerflush process, instead circulating dirty water around system. we find powerflushing system works alot better.

Powerflushing uses a pump and dosing bucket, this circulates the chemical around your heating system, one radiator is flushed at a time when they’ve all been flushed both directions then the system is done again using fresh water and dumping the sludge down the drain. System cleanse you just add the chemical for a few days and drain the system down, Not as affective as a Powerflush and may not remove all the chemical from your system, this then could cause other problems.

Powerflush requires equipment with a higher velocity pump and dosing bucket, it can also include a magnaclease, the equipment is attached to a suitable part of the heating circuit and flushed with chemicals to individual radiators, lastly the chemicals are flushed out of the system with clean water and inhibitor protection is introduced. A chemical flush is less efficient where chemicals are introduced to the heating system and left for a few days before draining system, refill and vent. BoilerOne recommend you instruct a gas safe registered engineer to powerflush your heating system.

Chemical flush is just putting chemical in your heating system and then just running the boiler in heating mode and getting all the radiators hot a few hours then draining down the system to change the water and fill up heating system and test that’s it. With a power flush machine. You put chemicals in far the power flush and you pump it around with a much stronger pump and you do every single radiator on the system by shutting all off apart from one at a time. And also the power flush machine should have magnets to catch all the sludge that builds up in the heating system. And you can keeping changing and flushing the heating much more quicker using a power flush machine.
