" Sentinal stuff seems rated by by pro-plumbers, certainly power flushing with x-800 worked well and moved a lot of muck out. So I am trusting to use the same brand for inhibitor based on the performance of the cleaner.
Time will tell if it was a wise choice. "

" 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!

By DIYDicky
, 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! "
