Squareback Style, 26"x14", 1" Tube, Titanium Element, 4.0kW, 115/230V, 26" cord Pigtail Ends and P-Switch Tap

This square back type heater was used in 2004 Islands spas and other hot tubs and they are back again!

Note that the new heater will may not fit around some older spa packs and in that case it is remote/separately mounted.

There will be discrepancies between the new and old unit.  

The new heater will have 3 wires, not 2.  Black and White go to the circuit board, and Green goes with the ground wires.
Also, the water connections may not be the same size depending on the original plumbing configuration of the individual spa. Any kind of reducer, such as a small piece of clear pipe set around the smaller connection will correct this.  You would then slip the larger connection over it.
