Excellent, very pleased
Exact model. Replacement was a breeze. Excellent service!
Exact replacement. Very easy to install. The HotTub was back in service in no time.
The only problem was the heater came with a wiring harness attached to the power terminals. My application did not require the harness and I found the terminals were "locktited" on which made removal difficult and the terminals could have easily been damaged. The advertised heater assy. did not show a harness attached.
Quality customer service, ordered on Thursday, delivery on Saturday. Installed as per instructions. Spa in service same day., works like a charm. Very pleased.
The heater assembly came with two nuts on the studs where the power is hooked up. After installing the heater in place, I started taking the nuts off with the proper size wrench. The first nut came off no problem. Shortly after I started loosening the second nut, which was stiffer than the first, the stud broke off at the bottom where it meets the heater tube. I used very little force, and the nut did not turn very easy. The failure appeared to be as a result of the nut being partially seized on the stud from the factory, and the stud being very weak where it attached to the heater tube.

This part is working very well . Easy to install.
