Hello, I have just had my 15year old Grundfos UPS 15 50 replaced with an Alpha 1 and the Alpha 1 seems quite a bit noisier than the the old one,
I have a new UPS3 sitting in a box and I am thinking of changing the Alpha 1 for the UPS3
if I understand it correctly, Alpha1 v UPS3
1. Alpha 1 is more energy efficient
2. Alpha 1 is noisier
3 Alpha 1 flow rate is much less
is this correct?
thanks
