Vitcas Central Heating System Inhibitor 1L is a high‑performance treatment designed to protect domestic and light commercial heating systems from corrosion, limescale and sludge build‑up. One 1 litre bottle treats up to 100 litres of system water (around 10 standard radiators), helping to maintain efficient heat transfer, reduce boiler noise and extend the life of boilers, pumps and radiators. The inhibitor is compatible with mixed‑metal systems including steel, copper, brass and aluminium, and can be used in sealed or open‑vented fully indirect systems, including micro‑bore plastic pipework. Regular use helps prevent cold spots in radiators and reduces the risk of blockages and breakdowns, making it ideal for use after system cleaning or power‑flushing
