Vitcas Central Heating Boiler Noise Silencer 1 Ltr



Vitcas® Central Heating Boiler Noise Silencer is a non-acid boiler descaler which stays in the system for life; no need to flush. Noise Silencer is compatible with plastic tanks, microbore and all metals (including aluminium) used in central heating systems. Vitcas Boiler Noise Silencer is only suitable for fully indirect systems. Not suitable for use with PRIMATIC single feed cylinders. Knocking and kettling can be especially irritating in the early hours or at night. Noisy boilers are usually attributable to hard water lime scale and sludge deposit formation on the heat exchanger surfaces. These deposits also reduce heat transfer which increases fuel bills and reduces the service life of the boiler. Vitcas Boiler Noise Silencer will remove scale and baked on sludge deposits and prevent them from reforming, thus restoring heating efficiency while reducing the noise and extending the life of the boiler.
