I got a Largo 8-10gpm 115v vertical, and with 60 degree water I am only seeing 124 (64 degree rise) with my 8gpm, and I can get about 175 (115 degree rise) if I hook up my 4gpm. I bought it about 3 years ago and have only used it 5 times or so, but I was skeptical right from the beginning so I finally decided to measure today. I am trying to get a hold of them but no luck yet, any ideas on what’s going on? Should I not be able to hit about 130 degree rise with my 8gpm?
