Slimchance,The newer high efficiency motors operate alot warmer than older mid efficiency units so this becomes a hydro consumption vs. longevity issue. In my application at work I would much rather have the lower efficiency motor with big bulky windings that lasts 20 yrs than some of the newer motors out there.
Is it because the newer, high-efficiency motors are much smaller, and therefore spread the heat out over a much smaller area - and thus feel hotter?
If there is one thing I noticed that remained consistent regardless of what tub manufacturer I researched is that they all out source their pump motors, (AO Smith, Emerson, etc...). Since they play such an integral role in the overall enjoyment of your tub ie: hydrotherapy, noise, is there some advice on what to look for and what to stay away from? Is one brand more troublesome then the other? What do you look for to minimize the noise which was very important to me?
You're not going to get a straight answer on this question here. Because this site is mostly dealers, not technicians. The dealers will back the tubs they sell, regardless if the motors are prone to problems.
