You are buying a 5.5KW Heater Complete Assembly includes Tube, Element, Metal Case and connecting wires. This unit features a high limit holding tab and a port for the pressure switchThis Heater Fits Cal Spa Hot Tubs and Is a Perfect replacement for the XL Heat Exchanger. The biggest difference is this Heater has a replacable element the XL Heat Exchanger doesn't you have to replace the entire heater when it fails. In the picture portion of this Item you will see an original heater mounted in the tub and burned on the left side this heater was engaged while there was no water in the tub and it caught on fire. A regular heater like the one you are purchasing will not catch on fire like that. The other two pictures are of the outside of an XL Heat Exchanger and the inside of one that burned and was tripping the breaker.

Note: The Company that was building these heaters originally has gone out of business therefore the heater available now no longer have and insulation wrap or a mechanical hi limit.. The reason is the element now is inside the water so you don't need either of those things like you did when the element was on the outside of the tube like the original heater you are replacing.. The great thing is in the future if you need to replace the element you can without replacing he entire housing..
