The longer/bottom heater will be used at night on economy 7 (if it still

If you run low you use the top one to heat a bit at the top on full rate
electricity.
We always have plenty of HW left at the end of the day. Perhaps I
should use the top one on economy seven to just warm half a tank?!
If there is enough it will save you money.
You can swap the wires and try it out.
