This can give rise to microbiological corrosion of iron or steel compoents. Scale in the heat exchanger will bd7593 a detrimental effect on boiler heat transfer efficiency.
Powerflushing is a particularly effective method of cleansing existing systems, especially those containing a high level of black magnetite sludge. Some systems allow the boiler to be operated at the same time, others may include some heating capacity of their own.
Prior to flushing by any method there are some common preparation steps. Recommends best practice for preparing the primary circuit of wet central heating systems prior to initial commissioning or re-commissioning following major remedial work e.
