Reference to WRC-NSF Test Procedure 1.50.220 using a 30 kW boiler. Time to reheat water store by
55°C - 25 minutes. Reheat time for 70% of store - 18 minutes
Note: Copper or Stainless Steel pipe MUST
be used between the cylinder, drain back
unit and collector. Solder connections
MUST NOT be used on the circuit between
the drain back unit and the collector
