I'm getting quotes for a new boiler and one of the RGIs has said he would use a magnacleanse to clean the system rather than a chemical clean or a powerflush. The magnacleanse appeals to me as it promises to remove a decent amount of sludge, but is a lot more gentle on the pipework than a powerflush - my pipework is about 30 years old, and downstairs is all under chipboard flooring, so wouldn't want to rip this up if a powerflush does any damage. The main downside of the magnacleanse as I see it (yet a touch of genius from Adey) is that the RGI would need to install fitments for the magna clean in order to fit a magna cleanse, so the customer has to buy and upkeep a magna clean.
Has anyone ever had a magna cleanse without having to have a magna clean fitted afterwards? Surely there'd be a way of connecting it to a system without using the Adey valves? Another thing is he said they normally fit new boiler then magna cleanse afterwards, which souds like madness to me. Why risk any magnetite going round your brand new boiler when you could do it on the old system beforehand. I don't want the magna clean to be fitted afterwards as I don't see the point in them. I'm getting mostly all new radiators as part of the work anyway.
On a side note, another RGI said a powerflush wasn't necessary (although he didn't test any system water) and just said to lob in a cleaner a week before he'd do the job. This sounded a bit too laid back for me!
