Do not waste your money or time.
Product did not work from the moment it was hooked up. It was installed by a contractor. The instruction manual is difficult to understand as it is written by someone that English is a second language. Sent back and ordered a REAL coates heater and it works beautifully! This was and expensive imitation. Dont waste your time and especially your money!

DID NOT WORK, I NEED TO CLAIM WARRANTY
IT NEVER WORKED, DOES NOT EVEN STARTS, AND IT WAS INSTALLED BY LICENSED ELECTRICIAN. THERE IS NO INFORMATION ABOUT HOW TO FILE A WARRANTY CLAIM. NEED THIS INFO.

Dont buy this!
This heater didn't even last a year. Pain in the butt from the start. You can buy cheaper as well.
