Page 7: Boiler Connection
The condensate from the WWK 300 is Reheat with boiler channelled to a drain via a hose (½” dia.). Where necessary, install a condensate pump (for part no., see page ). Connecting a circulation line to the cylinder The heat losses incurred in the circulation line and the electrical power consumption of the circulation pump, reduce the efficiency of the system. The cooled down water in the circulation line mixes with the cylinder content. Where possible, avoid installing a circulation line. Where that is not possible, control the circulation pump thermally or by a time switch. 3.4 Boiler connection (WWK 300 SOL) Pipe bends with union nuts are supplied with equipment which has heat exchangers Cold water installed, to enable easy connection to a safety assembly boiler.
