Excessive condensate from outdoor Bosch Heat pump

[Stude60]

Hello,
I am a homeowner that had a Bosch BOVB18 Heat pump installed Monday. This unit replaced a 25 year old Lennox unit. I have noticed the last two mornings with overnight temperature 30 degree's that I have standing water under the heat pump on the concrete. I looked inside of the unit and the accumulator and copper is covered with condensate and running out of bottom of unit. I never saw this in the 25 years with the Lennox. Is this a problem with the Bosch unit ? Any help appreciated, I am a novice.

It could be frost or ice coating the coils then it melts when the unit is off.

So is there an efficiency effect to that? I.e. the new more efficient unit extracts more heat per unit volume of outdoor air, and therefore causes condensation/icing to occur at higher outdoor temperatures, compared to the old unit?

Cheers, Wayne

Bosch unit uses thermistors and logic for the defrost cycle where your lennox didn't have any logic just was based coil and ambient temperature.View attachment 78373
