I have lost count of how many crap water heaters I changed that make "Chinese products look good" .But there only 12000 pesos and yes the quality of Dominican water heaters makes Chinese products look good.
I got one with the threads on the connection holes miss-threaded and I wasted a couple hours trying to get it to work before I took it back. Only then the ferretería told me "yeah that brand has that problem".
I said "So why do you still sell them ?
Until I got one for the main house that was a US brand made in Mexico at JDL in Puerto Plata.
I never considered going with propane. Only my wife cares about hot water at all.
