“I’m worried that the installer has installed the unit so that the bottom of the unit measures about 35cm higher up than the lowest hot water outlet. The instructions say that it ‘should’ be lower than the lowest hot water outlet. I just want to check if there are any likely consequences in terms of damage to the heater or if this is purely performance related? Does the unit need to be moved?”
Yes, we do recommend the Eemax water heater be installed BELOW the point of use (whenever possible) ….and also to improve time-to-temperature performance and to reduce water waste.
The unit does NOT need to be moved, but we do recommend the preferred mounting location for the reasons given above.
