magnacleanse

[eclipse01]

getting a new combi boiler installed in a couple of weeks..it is replacing an old myson apollo boiler which is 20+ years old..i asked about flushing the system out and was told that a chemical flush was the best thing as power flushing could cerate leak problems due to the pressure..after reading up on a few sites it would seem that this has happend in the past..i then came across magnacleanse which only uses the system pump to circulate the water and remove the sludge..advice needed on best thing to do..ie chemicals power flush or magnacleanse..i would like to go for the magnacleanse as it sounds the safest bet..anybody know anybody who has the kit and can do it..medway area..many thanks

what does your engineer intend to do? its part of install to clean the system to get warranty, agree to his quote and leave it with him.

a powerflush wont cause leaks due to its pressure normally, your new combi boiler will put more pressure on your radiator circuit tbh. What tends to happen with old systems is when powerflushing is removing sludge/corrosion it can show up weak points in the system caused by corrosion and cause them to fail earlier than they would in normal use. This does not mean its the cause, it has brought the failure time forward.

the type of flush required depends on the condition of the system, if the system is fairly clean then a basic chemical/mains flush may be all thats required, if the system is heavily sludged up then a powerflush is the only/best solution really. You can also consider removing the radiators and flushing them outside on a hose pipe.

fitting a large magnetic filter like the magnacleanse or combimag can be better than a chemical flush on its own, if you concentrate on each rad and use a vibration bit. This is not going to be anywhere near as effective as a powerflush tho. With a powerflush machine the biggest advantage is its flow rate of water.

i take it you have had a couple of quotes? have any recommended a powerflush?

I agree with galaxy_plumbing. A flush is part of the work to be done at the boiler installation or before.

A Magnaclean is still a good idea as it is protecting your boiler/controls/pump as long as it get serviced along with your boiler. This may or may not be in the price you have been given.

Make sure to ask your installer to add one if not included already. It is worth the money.
