Continuously Operated Re-Circulating Systems (Secondary Hot Water Circulation / Ringmain Installations)

 

A continuously operated re-circulating system is a water-replenished circulating system, which is maintained at a constant high temperature, to provide a continuous source of hot water. Continuously operated re-circulating systems are used to distribute constant hot water to draw off points that may be distant from the source, or hot water storage vessel. Continuously operated re-circulating systems are very different from conventional hot water supply and central heating systems found in domestic properties, for which our products have been tested to, under either BS7291 Class S or WRAS approval standards, and for this reason Pipelife products must not be used on any continuously operated re-circulating systems as they are not approved under the current version of these standards. The exception would be those systems which have been designed for domestic situations with intermittent temperature of less than a maximum of 65°C. This is in accordance with BS7291.

 

To summarize, a continuously operated re-circulating system is a hot water supply system which provides hot water to outlets, and incorporates all three of the following:

 

• Is maintained at a temperature above 60°C,

• Is replenished with an incoming water supply, to replace the water drawn to outlets,

• Is a pumped, circulating system.
