In hydraulic calculations, a constant pressure difference is generally used for group domestic hot water heaters. This is the maximum pressure loss expected within the unit when peak flow occurs.
The pressure losses to be expected at peak flow must be specified by the manufacturer of the group domestic hot water heater.
