Select a relevant time
We would normally suggest selecting
a time at the end of a DHW time
block so the DHW can be utillised for
the next DHW time frame. Usually
better timing during the day so there
are higher ambient temperature so
the heat pump can raise cylinder
temp most of the way without
needing to use back up heater.

As a guide only, to ensure the heat pump can re-heat the cylinder is one cycle so heating is not compromised. Times may
need to be shortened if heat loss is high for the property so heating performance is not compromised. Maximum is 120
mins for this parameter.
