Hydro-Quip 26-0011-7S-K Heater, 5.5KW, Cal Spa, XL 5.5, Aftermarket

The Hydro Quip 26-0011-7S-K heater assembly is an aftermarket replacement for Cal Spa OEM XL heat exchangers (5.5KW).

This is not a heat exchanger (the old inefficient technology with the element wrapping around the outside).
Instead, this drop-in aftermarket replacement has a newer design using an inline wet element inside the flo-thru tube (better efficiency).

It has two thermo grooves (with cover), a pressure switch tap and an aluminum metal box.
Pressure switch and sensors are not included.

The heating element is a 5.5KW standard element (not titanium).
With proper water chemical balance, standard elements can last a very long time.

This replacement may come with two additional wires with male and female terminal ends that are usually not utilized.
If your system normally doesn't use the additional wires, it is ok to conect them together, otherwise connect them they way your system noramlly uses them.
