The Balboa M7 Heater Assembly is developed with patented M7 technology for reliability and quality construction. It features a stainless steel housing and is front mounted for simple serviceability. Measuring 15" length with 2" x 2" unions and it uses 4.0 KW for efficient and fast operation.
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.
Fit was great, works awesome
This part is working very well . Easy to install.
Exact replacement that fitted quickly and works as expected.
Shipping was fast, worked great, just keep the nuts for the heater terminals as it doesn’t come with them.
Part fit perfectly. Hot tub is up and running again. Love this company, they always go above and beyond!!
I’m not sure who was texting me to help me get the right parts but they were a perfect match. Super easy way to figure out what I needed. I was even able to send pictures
I was surprised how quickly the part arrived. As expected the part fit perfectly. I would not hesitate ordering replacements part from these folks in the future.
Works fine; easy to install.
