3.11.4 DHW Cylinder Heat Up Test
A DHW cylinder heat up test must be completed for units in a system providing both heating and
DHW. The cylinder storage temperature should be set to maximum and the unit switched to DHW
‘ON’. The unit will now start up and begin heating the DHW cylinder. The unit will continue heating
the tank until it reached the setpoint or it can no longer get rid of the heat it is producing. If the
unit shuts down before the DHW storage cylinder reaches the desired setpoint, the heat
exchanger area in the DHW cylinder is too small or the flow rate is not high enough. The
maximum temperature that the DHW storage cylinder reaches should be recorded in the
commissioning certificate and the DHW cylinder setpoint should be set to 3 degrees below this
value. The thermal disinfection program will then need to be enabled to boost the DHW cylinder
temperature above 60°C on a weekly basis.
