Vitcas - Boiler Noise Silencer 310ml

Vitcas - Boiler Noise Silencer

Size: 310ml

Vitcas Boiler Noise Silencer is a non-acidic central heating descaler that reduces annoying boiler noise caused by limescale and baked-on sludge deposits on the heat exchanger. It stays in the system for life and does not require flushing, offering long-term noise reduction and improved boiler performance. This silencer is compatible with plastic header tanks, micro-bore pipework, and all common metals used in central heating systems, including aluminium. Suitable for fully indirect systems only.

Boilers that produce knocking or kettling noises are often affected by hard water scaling or sludge build-up on internal surfaces. These deposits reduce heat transfer, increase fuel usage, and shorten the boiler's lifespan. Vitcas Boiler Noise Silencer eliminates these problems by removing deposits and preventing their return.

Key Features

• Reduces boiler noise, including knocking and kettling

• Removes limescale and baked-on sludge from heat exchanger surfaces

• Improves heat transfer and overall energy efficiency

• Remains in the system permanently - no need to flush

• Safe for use with plastic tanks, micro-bore pipes, and aluminium components

• Ideal for use in sealed, fully indirect central heating systems

Application Instructions - Concentrated Cartridge

Vitcas Boiler Noise Silencer stays in the system and continues to prevent further scale and sludge build-up. Always use in conjunction with Vitcas Central Heating System Inhibitor for optimal long-term protection.
