Great best quality product. Recommended by most boiler engineers
Improved heat output on radiators and boiler became almost silent after using the Sentinal Descaler liquid.
I’ve been asked to review this product , well here goes , I don’t know , I put it in and ….. that’s it , how do I know what it’s doing . Simple answer . I won’t know whether it’s work until much later down the line . Maybe amend my review in a couple of years . Ciao for now
I always use this when needed. Write details on container to leave with boiler.
This product is easy to install as described on the instructions
My central heating doesn't have trapped wind any more.
Sentinel have always provided good quality products and this one does the job.
Does the job! Always a welcome addition when draining a heating system or cleaning out the MagnaClean filter.
Good product. I got a flexi tap connector and drilled through the cap and put the one end on the connector and the other on the radiator.
i have used this,yearly,for a number of years...seems to do its job..
Put in a system after I'd drained it. Quick tip for the DIYers out there. If you have a magnaflow or similar magnetic filter then use that to introduce this to the system.
Using sentinel x100 every year on my central heating system. Work well preventing radiators rusting inside.
Does exactly what it is meant to do and works well
Added to my radiators and forgot about it.
Not found any issues, no leaks, just seems to work.
time will tell but if it works as it claims for what it cost you cant go wrong
Not sure how to rate this product without draining the heating system to check whats in the water. I'm sure it foes what its supposed to do.
Sentinel X100. Good stuff, does the job.
Excellent quality.
Great stuff quieter system since I put it in. I'm convinced it makes my central heating system run more efficiently.
The product was reduced in price as tool station do from time to time, plus as always easy to order of the app and then go collect.
As you can’t see this stuff working it’s difficult to say if it’s good or not, do I have black water in my rads, no do I have a lot of gas coming out of my rads, no so I assume it’s working ok.
