An automatic bypass valve should be fitted to all central heating systems and will help eliminate radiator hammer from noisy radiator valves, caused by excessive water velocity. This makes the heating system more efficient as well as removing irritating system noises. Radiator valve hammer can occur on all types of thermostatic radiator valves, but should never occur with a manual radiator valve.
