Flow noise through valves

It is strongly recommended that the differential pressure across the thermostatic valves should not exceed 0.2 bar to avoid flow related noise. A differential pressure regulating device such as an automatic bypass valve should be used.

System Cleaning

To avoid damage to the valves and the heating system components, and the formation of scale deposit in the hot water heating system, the system should be flushed and a proprietary inhibitor needed.
