I have hoped not to write this review. On 1/25 Freewater installed a Navien tankless water heater. I had them come out several times for leaking and then for thumping sounds on the wall. They gave me a 6 mo. warranty on their work. ($4,100) The owner was irritated that I kept calling. Little did I know that was the least of my problems. Then recently the water was not staying hot even though the temp was set at *165. (From the beginning) The second plumber wouldn't touch it and said I should just wait until it fell off the wall because it was already 1/2" from wall and rusted. Then sue the company. I just had the third plumber in to reinstall the whole water heater. Freewater had not installed it correctly. I had to spend another $2,300. The water temp is now at *125. The thumping is gone. The leaking and copper piping completely replaced. Then mounted safely on wall. Nightmare over. read more
