Treatment of Water Circulating Systems in Domestic Central Heating Systems as required by Boiler Manufacturer’s 1992.

All recirculatory water systems will be subject to corrosion unless an appropriate water treatment is applied. This means that the efficiency of the system will deteriorate as corrosion sludge oxides accumulate within the system. This sludge may damage the pump and thermostatic valves, cause boiler noise or induce circulation problems. For optimum performance the boiler and its associated central heating system must be flushed in accordance with the guidelines given in BS 7593:1992 “Treatment of water in domestic hot water central heating systems”. This must involve the use of a proprietary cleanser, such as BetzDearborn Sentinel X300, X400 or Fernox Superfloc. For long term protection against corrosion and scale after flushing it is recommended that an inhibitor such as BetzDearborn Sentinel X100, Fernox MB-1 or Copal is dosed in accordance with the guidelines given in BS 7593:1992.

"Failure to flush and add inhibitor to the system may invalidate the appliance warranty."

Method example.

Flushing and treatment process using CF30 electric power flushing unit using centrifugal motor with reverse flow and dump valves.

Seal central heating system and connect CF30 into the system via a radiator or heating pump. With all valves open, circulate at 50C for 30mins reversing the flow regularly. This dislodges loose sludge and corrosive debris which is then dumped to drain. At the same time system water is replaced with clean water. This takes approximately 3hrs.
1 litre of Sentinel X300 for new systems, or X400 for old systems, is then heated to 50C and added to the system via the CF30. The CF30 flushing unit chemically cleans the system circulating for 15 minutes to each radiator and circuit in turn. The flow of treated water is regularly reversed. This process takes approximately 4hrs.
Finally, the proprietary cleanser is flushed and dumped to drain. At the same time it is replaced with clean water and each radiator and circuit is flushed in turn. 1 litre of Sentinel X100 is then added via the CF30 and circulated for 15mins to be left in the system as protection against future corrosion. This takes approximately 2hrs.
