The Rated Condenser Inlet Water Temperature for the Coil:WaterHeating:AirToWaterHeatPump:Pumped object has to be more than 25°C (from Input Output Reference Guide, p. 1871: "Values must be greater than 25 °C. If this field is left blank, the default value is 57.5 °C"). Why this rule? I have a technical datasheet where the air-to-water heat pump (for SHW) is evaluated for water temperature between 10°C (entering, since it's coming from the municipal water-main) and 52,5°C (exiting).
