120 AC?DC water heater element
I have tried several DC hot water elements and so far none work as well as my test bench 120AC heater. I am using a standard 5 gallon hot water tank and wanting to use a 120AC element on top and a 48DC on the bottom. I have heard you can use 48DC directly on a 120AC but the efficiency will be very low. Is there any dual voltage operational hot water elements available that can use either AC or DC for equal performance?
