Used this after fitting two new radiators as system was slow to fill ,run for over two hours and left in overnight ,drained and refilled using no nonsense inhibitor so far system running ok only used to heat water so far but it does seem to be hotter,system certainly quieter.

Sentinel X400 System Restorer
We had a serious problem with noise coming from the pump in our open vented CH system.
I used Sentinel restorer to give the system a really good cleaning and then took care to flush this out thoroughly.
I topped up with Sentinel 100 inhibitor and the results have been great.
The system can now run hotter than before increasing the efficiency of the rads and making the house much warmer.
I would recommend these products to all CH owners.

Sentinel X400 Sludge Remover
Have been having problems with some of my radiators not getting hot, put the liquid in and within minutes the problem was cured. Could not believe how quickly it worked.

For the size of our ancient one pipe CH system, I had to buy two bottles...so a little pricey.
But what a difference! The boiler is a lot quieter, the water is a lot hotter and several of the radiators that were only ever luke warm are now hot.
We should have used it 10 years ago when we first moved in this property.
