Rated 5 out of 5 by from Excellent value Not used Screwfix before but had a boiler with a kettling problem and thought give a try at this price. After just a few days the kettling has reduced to just a slight level that hoping will improve with time. Combined with the cleaner rads and hot water are warming up a lot quicker then before. Good stuff

Rated 5 out of 5 by from NO MORE "CHUGGING" My central heating system sounded like a steam train "chugging down the line" 2 bottles of inhibitor and 6 hours later, it was that quiet I had to check the pumps/boiler were on. All was well and very very quiet. . Yet another great product from screwfix!

Rated 3 out of 5 by from quieter boiler Selling house and thought I would be a good chap and service the boiler, including a drain down and flush, followed by inhibitor. As a result I ended up with a bit of kettling afterwards which I didnt have before. I added this and it quietend it down to acceptable levels, which should get better over time I hope. Har dto compar eit with anything else an dreliability isnt really approprite for this product. - It did the job at an affordable price.
