The Alph Pros do have a CE listing, meaning it meets the requirements of the European Directives.  I suspect it is plenty safe, and possibly more scruntinized then UL requires? 

The manual included with the samples I have is printed in 26 languages.  Make me think there are plenty in operation, safely, across the world.

There was talk about bring them in with out UL?  Not many manufacturers like playing the waiting and money game with UL

Rumors I have heard indicated the long awaited Wilo ECO may in fact arrive without UL?  it’s been at least 2 years now that that circ is “on it’s way here”

I suspect Grundfos may be waiting to see how Wilo does with the sales of the ECO.  I have received mixed signals from Grundfos as to when and if the Alpha will be available.

Actually the Viessmann Vitoden uses a 15-62 VS Grundfos, 230V that I suspect is a close cousin of the Alpha pro.  Does it have UL?
