    It tastes divine

    I fell in love with this product at first sight. It wasn't only her reputation that attracted me to her, it was the affordable price and the fact that she would simply show up at my front door. Within a few days she was here asking to be undone and I took no time at all in getting to grips with her undoing. She's now coursing around my system performing her amazing feats, defying corrosion and silencing her critics. It's wonderful having her on board and I will be eternally in your debt. Many thanks for everything.

    System clean out and flush.

    Sentinel inhibitor x100 is marked with a quality guaranteed endorsed logo attributed to: BAXI, Worcester / Bosch, Ideal and The Energy Saving Trust. - So if the x800 cleaner is of a similar quality, then what more can anyone add?

    Heating Maintenance

    X100 help's to quieten down and prolong the life of pump's and boiler's it can be added with X200 (X200 is for noisy kettling boiler's) and your system should be good for a few more year's.
