This unit features a 5,5Kw Element, Tube with (2) M7 Sensors on either end with (2) Split Nuts and gaskets. This heater replaces the heater inside of the bottom of a Cal Spa Pack with the white insulation around it and the two sensors on each end that are pull tied onto the tube and plugged into the board because the element is welded to the tube.. That style has the heater element on the outside of the tube this style has the tube inside of the tube that is why this one has the M7 sensors inside the tube and not pull tied on.. See the last picture for what the original heater that this replaces looks like.. Shipping in The United States is Free. Please Choose with Care as We Do Not Accept Returns.
