We installed our first two heat pump water heaters this month, both in basements in Somerset County, and now my boss says we should both get the 608 "just in case." I always thought the 608 was strictly an HVAC thing.
From what I can tell the units come sealed from the factory and we're just doing the water, the condensate and the venting clearances (an electrician did the circuit). So when would a plumber ever need it? Warranty work? If the compressor side ever needs service? I apologize if this is obvious to the HVAC people here.

Thank you all. So: it's cheap enough to get anyway, and if one of these ever needs the sealed side opened, I'd rather be the one he sends. Signing up for Core and Type I.
