An Old Favourite

I have used this product for over 30 years and it still does exactly what it should. Designed to be installed via the F&E tank, (another Fernox product is for injection via a red bleed valve), it prevents corrosion (and resulting gasses) and reduces boiler noise. Always keep some back to dilute with the final water stored in the F&E tank.
