Hard water contains calcium and magnesium ions. When hard water is heated these salts form as hard scale inside hot water appliances and adjoining pipe work. The build up of scale will continue as more and more salts are deposited and will this lead to blocked hot water heat exchangers, particularly in Combination Boilers. Descale A is formulated as a heavy duty acid based descaler for boiler systems , pressure washers etc. It removes contaminants and lime scale build up which can cause failure of systems through the build up of scale. Add Descale A to the system and run until all contaminants are removed. Drain down and repeat if necessary. Fully flush the sustem with fresh water after use. In sealed systems add an inhibitor to the system to prevent further build up of scale Descale A cleans corrosion deposits
from radiator systems and main heat exchangers of a boiler and removes hard
water deposits out of a combi boiler. Descaling is needed when a heat exchanger accumulates a significant thickness of calcium on it's surface, enough to insulate the water from the heat source and impair performance. This effect usually only occurs on heat exchangers that carry fresh tap water. Sealed systems such as radiator circuits usually contain an inhibitor. There will be a small amount of calcium that was contained in the initial fill of water but once this has precipitated there is no more left to deposit. Fresh tap water particularly in hard water areas, will constantly deposit calcium resulting in very thick layers of scale which can virtually seal off all water flow in extreme cases. Combi boilers and thermal stores suffer from this in particular. Symptoms of scale build up include reduced water flow, reduced temperature, wildly fluctuating water temperature, or any combination of these. |
