Abstract
The corrosion reactions that are likely to occur when bare steel is exposed to water in domestic central heating systems are discussed and the resultant effects are related to corrosion of radiators per se, and to the ancillary occurrence of hydrogen gas-locking in. radiators and to blockage of pumps by loose magnetite.
The suggested remedial measures include care in installation to prevent air ingress into and water leakage from central heating systems and the use of corrosion inhibitors.
