What do people think of these devices. Are they worth bothering with? Which would you recommend? The Spirovent appears to be the better quality and do more.

I'm just having a Atag system boiler with Santon tank pressurised system. The radiators have been replaced but I think the runs to the radiators are the same. The plumber has said he has flushed the system (I take it was to clear the old pipes he has reused to the radiators.)

Also do you normally have inhibitors etc. in pressurised systems? I'm reading quite a lot online but just getting more confused.

Thank you,

Si

Magnaclean > Spirotech imho, and independent testing seems to back that up.

Chemical inhibitors are vital to prevent limescale build up and galvanic corrosion, in the same way that you wouldn't run a car engine with just water in the coolant system due to the resultant internal corrosion and limescale deposition. This applies equally to vented and pressurised systems.

In a domestic heating system, your steel radiators will become the sacrificial element in the presence of copper, and slowly dissolve leading to a build of up hydrogen gas and magnetite sludge, both of which will reduce the efficiency and life expectancy of the system.

Thank you for the quick response. I am not quite sure how independent that test is considering it appears to be chosen by the company that make the Magnaclean. Still they are impressive results.

What is the difference between the two Magnacleans? When would you pick one over the other?

The twin-tech filters out non-magnetic particles, but is more expensive.

Imho, if you didn't want to splash out on that, then the standard version is still going to be very beneficial when it comes to keeping your system free of magnetite build up which is the more serious issue, especially if you're using chemical dosing and having had your system flushed already.

The twin-tech means you've covered all the bases though for peace of mind and for keeping your system running as efficiently as possible, and for the sake of ~£40 over the standard magnaclean it's not huge sums, but £40 is £40.

I've installed a few magnetic filters and Magnaclean impressed me the most. Easy to take a part and clean and seem to be made of better quality plastic than others.

Just make sure you don't do what I've seen some idiots do and not leave enough clearance above the filter to withdraw the magnet for cleaning!

Magnacleans always seem to have trapped dirt everytime you take them apart, problem is they leak if you look at them! spirotech feels like a much more quality product and makes draining very easy problem is every time you empty one you either just get water or a few tiny particles. In theory both are a great idea and if the magnaclean was a quality, reliable product would win hands down, trouble is they're not.
The "independant testing" is rubbish because Spirotech say theres holds the same and is superior!
Although Ive been tempted to fit a magnaclean on my own boiler I would always need to keep a bucket under it and also make sure everytime I cleaned it I would have to replace the seals to be on the safe side and re-check it every day for a month for fear it would be leaking.
This is all my own experience from fitting many magnacleans and spirotechs, and also from repairing leaks on more magnacleans than I can remember!
