"Does a good job of keeping the system healthy. Best to clean with X400 (or X800), flush and then put X100 into the system. Add X200 for additional protection and improvement in heat transfer properties of the water"

Slap it in!
23-Nov-2012
By
, Staffs
"Bostin' stuff this. Slap 2x bottles in for good measure (you can't over-dose) + a bottle of scale inhibitor and prepare to be blown away! Maybe not quite, but this will make your boiler shut up faster than a hungry dog at tea time. A bit pricey, but hey, you only do it once!"
