balboa heating elements

[Kathio]

I have a 4kw balboa heater on my hot tub. Can I replace just the element or do I have to replace the entire silver tube? Thanks for any help.

Most Balboa heaters have replacable elements. The non replacable elements would be welded in the manifold, the replacable elements would have two bolts holding the element in place which would be visable.
