Internal protection for central heating systems. Inhibits limescale and corrosion.

For the most effective results, systems should be flushed and cleansed.

A triple blend of Corrosion Inhibitors. Specific for steels, aluminium, copper and their alloys and most materials found in heating systems.

1 litre of H+1 INHIBITOR is enough to protect and preserve 100 litres of system water. Will protect and presrve up to a 10 radiator heating system. Must be left in the system!
