Did you know that a tankless heater like those south of 44 require MORE Maintenance than a tank heater?
The maintenance is isolation of the heater via the valves below it and running vinegar through it by a pump for 30 minutes. Unlike Retired guy and most everyone I maintain my water heater. I am surprised that no one seems to be aware of this. With no maintenance expect less than13 years from one, with maintenance expect at least 20.
