This company knows there’s an issue with there tankless water heaters and comes up with excuses after you send them requested pictures. My water heater is clearly inside so it can’t freeze but they stated that was the issue and they won’t warranty it. It appears the weld on the heating tube wasn’t properly welded from the manufacturer and it separated. I’m out of $485.00 having this unit for a very short time. This company is also affiliated with the company Rheem.
I will also show Lowes and Home Depot this issue with an engineer to show this is the case and why individuals are having water leaks all the time.
